I watched Er Chuang’s short video, and everything went numb!

[In addition, the harder the sword is, the better it is. ]

[It is better to have a combination of hardness and softness like the Han sword in Liu Sheng's tomb. ]

[Because for steel, the higher the hardness, the worse the toughness, which is an irreconcilable contradiction. ]

[And if the toughness is low, the sword will break in a collision. ]

……

Many dynasties and planes.

Many ancient blacksmiths nodded.

Too hard to break, this is the basic common sense of forging swords.

But insufficient hardness is not good either, so we must strike a balance.

……

[In the "Sword Forging Competition" which is very popular abroad, there was a scene of a broken sword. 】

[It's not because the hardness of the knife is not enough, but because it is too hard and not tough enough]

[And a broken knife is very dangerous. There are almost every year in the knife circle where the broken blade flies and cuts oneself. 】

……

Accompanied by narration and subtitles.

Some videos of the "Knife Forging Competition" were inserted into the high-altitude giant screen, and there were also cases of broken knives.

The plane of Emperor Taizong of the Tang Dynasty.

Looking at the high-altitude giant screen, Li Shimin became very interested in the "Knife Forging Competition".

People from all over the world compete with each other in knife forging skills to see who forges the better knife. He thinks it's interesting.

Suddenly.

He said to Li Jing:

"Pharmacist, what do you think about our Tang Dynasty also holding a similar competition? Can it help improve the level of Tang Dynasty's weapons and equipment?"

In his opinion, not only knife forging, but all kinds of weapons can be compared.

See who can make weapons with greater power and wider application range.

Although the future of the Tang army is definitely hot weapons.

But the industrial revolution will not be achieved overnight, and it will take a short or long process.

Therefore, Li Shimin thinks it is reasonable to improve the level of some cold weapons before that.

Hearing Li Shimin's inquiry, Li Jing immediately replied:

"Reporting to Your Majesty, I think this is a great thing."

Li Jing expressed his agreement with Li Shimin's idea.

Hearing this answer.

Li Shimin nodded slightly.

……

At the same time.

On the other side.

Many blacksmiths from past dynasties looked at the various metal processing equipment used by the participants of the "Sword Forging Competition" on the giant screen, such as power hammers, grinders, hydraulic presses, etc., and were very envious.

Compared to the forging equipment they use, these equipment 23 are simply too easy to use.

……

[Based on personal experience, modern steel can indeed be made harder. ]

[For example, the hardness of ATS34 stainless steel can reach 60HRC, the hardness of Damascus steel is 63, and the hardness of HAP72 steel can reach 70. ]

[However, these modern high-performance stainless steels with a hardness above 60HRC cannot be made separatelyTo make a qualified long sword. 】

[Because they are too hard and not tough enough, they are only suitable for making short swords within 30 cm in length. 】

[Because within this range, the toughness of the knife is not high. 】

[And to prevent the knife from breaking, you can also use the method of sandwiching steel or thickening the blade, and the weight of the thickened blade is also within the range of human tolerance. 】

[So, within this range, the performance of modern high-tech steel is basically crushing that of ancient steel. 】

[But you can't take a dagger to the battlefield, what's the difference between that and suicide? 】

The bullet screen flew out:

"Not really. Modern carbon steel contains rare metals such as silicon and manganese. It can ensure that the hardness is usable and the toughness can be very good. The blade can be bent 90 degrees without breaking in the test."

"Reply-Yes, modern stainless steel with a hardness of more than 60 is indeed too hard, but modern carbon steel is not like that. It has both hardness and toughness. Some high-level knives can even be bent 90 degrees repeatedly from left to right several times without breaking."

"Reply-because the ancients would not consciously add a small amount of other metals in the right proportion to make alloy steel. So in the field of carbon steel, modern times are crushing."

"..."

Many swordsmiths and blacksmiths in the past dynasties looked at the giant screen in the sky and firmly remembered the information that other metals can be added to steel.

However, they still lack more knowledge about these rare metals called silicon and manganese at this time, and need to slowly explore them later.

But no matter what, for them, this is like helping them open the door to a new world and pointing out a new direction for them in forging.

……

[More importantly, in cold weapon battles, weapons have better performance. Although there are advantages, they are not absolute advantages. ]

[Fighting skills are far more important than weapon performance. ]

[In the unarmored state, the most important thing to do in cold weapon battles is not to be hit. ]

[In this case, it doesn’t matter how hard the tip of the knife is. The key is to master superb fighting skills. ]

……

Many ancient generals in the past dynasties nodded.

This is indeed true.

In the cold weapon era, a weak person, even if holding a magic weapon, can’t exert much power.

However.

Then again.

If the strength is similar, the weapon advantage is still very important.

Therefore, it is also important to equip weapons with better performance.

……

[However, using modern alloys to make armor does have a greater advantage over ancient armor. ]

[Because now alloys can ensure stronger hardness while being lighter. ]

[Many people always think that armor should be stronger and have a larger protective area. ]

[But in fact, armor requires that it should maintain basic defensive power.Under normal circumstances, it should be as flexible and as light as possible. 】

[Because no matter how strong the defense is, if it is too heavy, it is just an iron coffin. 】

……

The plane of Emperor Chengzu of the Ming Dynasty.

Zhu Di nodded slightly.

This person from the later generations seems to have a certain understanding of cold weapons.

Except for those generals with natural supernatural powers and heavy cavalry, armor cannot be too heavy, otherwise it will reduce mobility on the battlefield.

In this way, the gains will outweigh the losses.

……

[In ancient times, whether in China or abroad, the weight of full-body armor was generally about 40 to 50 kilograms. 】

[Although there are some heavier armors, they are very rare. 】

[After all, even if you can bear the armor, you still have to consider the feelings of the horse. 】

【No matter how flexible the armor is, it is equivalent to adding 40 to 50 kilograms of weight to your body out of thin air, and your flexibility will also be greatly affected. 】

【There is a big difference between being able to make an action and being able to make an action easily. 】

【For example, wearing full-body plate armor, you can do the action of falling to the ground and getting up, but in fact, falling to the ground on the battlefield is basically close to death. 】

【After all, although you can make the action of getting up, but when you want to get up wearing 40 to 50 kilograms of armor, it is much more difficult than when you don’t wear armor. The enemy will not give you time to slowly get up. 】

【Although the materials now can make much lighter iron armor, but the defense is almost the same, this can really be regarded as a treasure armor in ancient times. 】

The bullet screen flew out:

"Modern titanium alloy plate armor is nearly half the weight of the same specification steel armor. It would be invincible in ancient times."

"Nowadays, it is not necessary to use steel to make armor. Use polymers, stab-proof fabrics, etc., and refer to explosion-proof clothing for upgrading."

"If it is cheap, fiberglass is the most suitable. It has strong plasticity, is light and tough, will not be weak in the face of cold weapons, and can also resist some blunt blows."

"Based on my experience in participating in modern full-armor fighting competitions, you can use armor made of titanium alloy and modern special steel, cloth made of modern fibers such as Kevlar, and built-in armed clothes also use modern fibers, built-in non-Newtonian bodies, artificial cartilage and other materials for buffering."

"..."

Many ancient people in all dynasties were really stunned by the various discussions in the bullet screen.

In terms of making armor, later generations are really far ahead.

The armor that can be made in later generations is not only more protective, but also lighter.

It is simply too strong.

Looking at the various material names mentioned by people in later generations.

Many ancient people sighed sincerely in their hearts:

"Science and technology are indeed the primary productive force."

...

[But, having such a treasure armor does not mean that you can be invincible. It depends on who wears it. ]

[And, don't say that only one set of armor is taken to the ancient battlefield.It is useless to have a field. Even if the armor is equipped in an organized manner, it can only be said to have an advantage in the war, but it cannot be said to be a sure win. 】

[In ancient times, there were many cases where the army with a higher armor rate was beaten to a pulp by nomadic barbarians with a lower armor rate. 】

[Equipment is important, but it is not just weapons and equipment that determine the outcome of a war. 】 (To read the novel, go to Fulu Novel Network!)

…

The plane of Emperor Taizong of the Tang Dynasty.

Li Shimin nodded.

The combat effectiveness of an army is related to many factors, such as the ability of the army commander, the number of army personnel, the military strength of the soldiers themselves, and the army's weapons reserves.

It is impossible to judge by a single element.

The outcome of a war is also affected by various factors such as the time, the place, and the people. Whether the weapons and equipment are good is only one of them.

Of course.

If it is a cross-level crushing of hot weapons against cold weapons, it is another matter.

In short.

The armor rate of the army has an impact on the combat effectiveness of the army. The higher the armor rate, the more chances the army has of winning in combat.

But to say that this is the winner of the war is obviously impossible.

……

[Finally. ]

[What will happen if modern swords are really used to cut ancient armor? ]

[In other words, can swords made of modern materials break the defense of ancient armor? ][]

[Has anyone really done this experiment? ]

……

Many ancient people in all dynasties looked at the giant screen in the sky with more concentration.

They are very curious about the results of this experiment?

……

[He used armor plates made of 304 stainless steel to conduct the test. 】

[304 stainless steel belongs to austenitic stainless steel and cannot be quenched. According to the national standard for hardness of 304 stainless steel: Brinell hardness: 187HB; Rockwell hardness 90HRB; Vickers hardness 200HV. 】

[This hardness is too soft, even lower than the lower limit of HRC, and this hardness is equivalent to unquenched soft steel. 】

[Basically, it can be equivalent to the relatively poor armor in ancient times. 】

[For the knife to cut the armor, he used a heavy machete with T10 steel covered with earth and burned blade. 】

[The hardness of the knife with earth and burned blade is at least 58HRC. 】

[Moreover, this heavy machete weighs about 1.6 kg, which is the weight of a two-handed sword. 】

[So, in terms of the power of slashing alone, it is better than a one-handed sword. 】

[Moreover, it is impossible to perform a powerful swing in battle, and the opponent will not give you this opportunity. 】

[The power of the powerful swing in the trial slash test must also be far greater than the swing force in battle. 】

[So for this test, the power will only be greater, not less than the power of a normal sword swing in combat. 】

[Result. 】

[He used a heavier, harder, and sharper machete to chop the armor at a vertical angle, and despite the huge hardness difference of more than 40HRC, he was unable to cut the armor plate, which was only hardened to soft steel. ]

……

Accompanied by narration subtitles.

The whole process of watching the armor experiment was played on the giant screen in the sky.

After watching the experimental results.

Many ancient people felt that the knives forged in later generations were not much stronger and could not break the armor.

But some ancient people felt that the knife in this experiment could not represent the highest level of knife forging in later generations.

After all, later generations were in the era of hot weapons, and they would not invest much energy in cold weapons.

The knife used in the experiment might be just an ordinary civilian knife.

So, the results of this experiment are not necessarily reliable.

……

[This result is enough to prove that modern knives cannot cause effective damage to enemies covered by ancient iron armor. ]

[It is obviously impossible to think that you can kill people in ancient times with a sword made of modern technology. ]

[Not to mention the old-fashioned sword breaking armor. ]

……

After a brief conclusion.

The video ends.

……

On the giant screen in the sky.

The video refreshes quickly.

A new video appears.

[Magic transformation of Confucianism, creating wonders? The origin and evolution of Neo-Confucianism! ]

……

Spring and Autumn and Warring States plane.

Confucius saw the title of this new video and his face changed slightly. 777

"What is Neo-Confucianism?"

This question popped up in his mind.

The eight words in the title "Magic Reform of Confucianism, Creating Wonders" are not a good evaluation.

This seems to indicate that this Neo-Confucianism has done bad things to Confucianism.

Thinking of this.

Confucius's eyes looking at the giant screen in the sky became more focused.

He became more interested in this Neo-Confucianism in later generations.

……

[In the winter of 1672, in Tancheng, Shandong, a woman named Wang and her husband Ren broke up. ]

[On the one hand, the husband had a habit of domestic violence, and on the other hand, Wang also had an affair. ]

[Later, Wang got her husband drunk with wine and eloped with her lover. ]

[However, life is not a novel, there is no such thing as a couple living together. She was soon abandoned by her lover and hid alone in a Taoist temple near Tancheng. ]

[Soon after, she was found by her neighbors and husband. 】

【Because of this incident, Ren was ridiculed by his neighbors and bore a grudge against Wang. 】

【So on a snowy night, he pressed his wife Wang on a newly bought straw mat, pressed her with his knees, strangled her to death, and then abandoned her body in the snow. 】

【This case was recorded in the "Tancheng County Chronicle" written by Feng Kecan in 1673. 】

【The famous historian Mr. Jonathan Spence also wrote his masterpiece "The Death of Wang" based on this case. 】

【If this case happened in modern times, Ren should be convicted of intentional homicide and sentenced to death, life imprisonment or more than 10 years in prison. 】

【But at that time, the local officials believed that Ren's killing of his unfaithful wife was justifiable based on the mainstream "Neo-Confucianism" classics at that time because his wife cheated on him and fled first, and released him. 】

……

Read the whole case.

Many ancient people in different dynasties felt that there was no big problem with this verdict.

The reason is also very simple, because the wife in the case cheated on her first, which was a very serious fault for women in ancient times.

In the eyes of many ancient people, the murder of the cheating wife was also her own fault and she deserved it.

Even in the laws of many dynasties, it was stipulated that killing a wife in this case was not a crime, or it was lightly sentenced.

The most outrageous one is the provision of the "Great Ming Law".

It stipulates that if a husband kills his wife and the adulterer on the spot, he is not guilty, but if he only kills his wife and not the adulterer, he is guilty.

……

[Why is this "Neo-Confucianism" so weird in solving cases? ]

[As a branch of Confucianism, has it been so harsh from the beginning? What kind of historical changes are behind this? ]

[If you want to figure out these questions, this video will give you the answers. ]

……

After watching the preface of the video.

Many dynasties before the Northern Song Dynasty.

Many ancient people continued to look at the giant screen in the sky.

Although the previous cases made them feel that there was nothing special, they were still very interested in understanding this Neo-Confucianism that was modified by the people in the future generations of monkeys.

After all, since the reign of Emperor Wu of the Han Dynasty, Confucianism has been the official orthodox doctrine of the ancient Chinese dynasties.

These ancient people wanted to see how he had changed Confucianism.

Why did people in later generations say that he had created something strange? .
