The Lone Star of the Tang Dynasty

In such a situation, Lu Changgeng's heart swelled with a decisive aura: Even if the opponent may really have the help of immortals, we and other families will join forces to attack, and every move will not be resolved!

After thinking about it for a while, Lu Changgeng decided that he still had to take action, and he couldn't be sorry for the foundation accumulated by his ancestors for several generations!

When all the old men heard Wang Jing's statement, their eyes were focused on him, full of expectation.

Someone asked: "Brother Wang, among the five surnames and seven hopes, the Taiyuan Wang clan has the strongest power, how to deal with it this time, and ask Brother Wang to point out the direction!"

Wang Jing, who is usually silent, gave an unusually clear answer at this moment: "Pen, ink and paper, these are all things that Li Er can make or find substitutes for...... But what about the irreplaceable? Our most urgent task now is to start with these irreplaceables. "

After hearing this, everyone agreed.

Although Li Er was able to produce high-quality paper, even surpassing the Qinghe Cui clan, pen and ink seemed to be monopolized by Fan Yang Lu's family, but in fact, as long as there were items that could leave traces on the paper, they could replace pen and ink, and even poor scholars used rags dipped in rat blood to copy books when the price of pen and ink was high.

However, ......

What exactly is irreplaceable by Li Er?

This question weighed on their minds like a boulder, and became the key to the next strategy.

"Indeed, it is not easy to find resources that Li Er cannot replace. "

Lu Changgeng frowned and thought about it, looking around, "The various resources that our family has at their disposal are rich and diverse, even if Li Er is resourceful, it is difficult to fully compete with us. But what kind of resource is truly irreplaceable?".

"You don't have to rush. "

Wang Jing smiled leisurely, his voice was calm and powerful, as if it contained endless wisdom, "In fact, the answer is right in front of you, and that is ......."

"Iron!" he spat out word by word, and the room was instantly filled with a sound of surprise.

"Iron?" everyone wondered.

One of them interjected: "However, it is rumored that Li Er has been studying the method of forging a new sword recently, and the iron it refines is of excellent quality and extremely sharp, which is ......

."

Another old man was also worried: "I heard that Li Er seems to have mastered some kind of iron-smelting secret technique, if we rashly attack the iron, I am afraid that we will encounter unprecedented resistance." "

In this regard, Wang Jing still maintains that indifferent smile, with deep and far-sighted eyes.

"You misunderstood, I'm talking about iron ore, not finished iron. "

He explained, "No matter how proficient Li Er is in the art of iron smelting, he still needs to refine refined iron from ordinary rough iron. If we can control the supply of ordinary iron in circulation, then ...... How will Li Er deal with this situation?".

As soon as these words came out, the room instantly fell into a dead silence, and everyone fell into deep thought. After a while, everyone nodded secretly, and they all admired in their hearts: Clever plan! Even if Li Er has excellent wisdom, he can't conjure up iron ore out of thin air! Such a move to draw wages from the bottom of the kettle may be the key to restraining Li Er!

......

Zhuangzhong Laboratory ......

Li Changge's eyes were fixed on the clear liquid in the beaker, like a warrior examining his trophies, his face full of exhaustion and relief.

"It's finally working!" he whispered, the liquid was not ordinary, but sulfuric acid, which the world had heard of.

Sulfuric acid is often seen as the embodiment of sin in the world, and there are many cases in the news about it as a tool of crime. However, in the field of industrial production, sulfuric acid has an irreplaceable position, and it can even be said to be one of the most important raw materials, and it is not an exaggeration to remove "one". It is the cornerstone of the chemical kingdom, and through a series of redox reactions, countless different chemical products can be derived.

Previously, although Li Changge had also refined sulfuric acid, the purity had never been able to meet the standard.

The purity of standard industrial concentrated sulfuric acid is as high as 98%, and his attempts have been stuck below 50%. As spring turned to summer, after some hard work and unremitting efforts, Li Changge finally mastered the technology of making high-purity concentrated sulfuric acid in this sunny summer.

At this moment, concentrated sulfuric acid can not only be used to make high-quality glass, but also the key to unlocking the chemical industry chain.

Next, sulfuric acid will help Li Changge to further prepare nitric acid, which means that the explosives are no longer coarse black powder perfunctory, but genuine high explosives. In addition, nitric acid can also be used in the production of chemical fertilizers, bringing significant scientific and technological improvements to modern agriculture.

This series of achievements makes Li Changge excited, just like a student who has achieved good results in the college entrance examination or saved up to buy a long-desired sports car, he must see these achievements with his own eyes every day to be satisfied.

On this morning, Mian'er Ying'er had urged him to go out outside the door, and Li Changge, who was dressed in a black suit, promised them to have a holiday on the first day of the first day of April, go out hunting and play together, and enjoy the fun of team building.

Although the two maids are still unfamiliar with the word "team building", their expectations for going out to play are overflowing, and they get up early and carefully groom their makeup.

Time slipped away quietly, and it wasn't until three o'clock in the morning that they packed up and set off.

At the turn of spring and summer, the sun is shining and picturesque, and the three of them are galloping on the field outside Youzhou City, and they are in a very comfortable mood.

Li Changge encouraged the two maids to keep learning and improving, hoping that one day they would be able to drive a bloody horse, instead of the current dwarf horse.

At this moment, the sound of horses' hooves and shouts suddenly came from the forest, and several Turks with strong hair and leather armor appeared in view, fiercely shouting for looting and leaving the girl behind.

Mian'er Ying'er was so frightened that her face was pale, while Li Changge was calm, calmly took off the bow and arrow behind her back, and ridiculed each other in the face of threats.

Seeing that Li Changge was so calm and arrogant in his words, the Turks were stunned for a moment and couldn't believe it. But they were not intimidated by the bowing skills of the Southern Dynasties, and drew their swords to rush forward.

Li Changge sneered secretly, thinking that although he had not been an Orion for many years, this extraordinary archery technique might still have a place.

Just as the two sides were fighting each other, a loud shout suddenly sounded in the forest, and a burly man galloped out of the forest, and with only a few charges, all the Turks were cut off their horses.

Dahan put away the big axe in his hand and greeted Li Changge with a fist: "Don't come to Gongzi unharmed! Chang'an Chen is here, he has had the honor to listen to the sound of Gongzi's Qinse, see Gongzi's talent, and even hear that Gongzi knows everything about astronomy and geography, so he is here to visit him today!"

It turned out that this heroic man surnamed Chen had already admired him, and specially rushed to help and ask Li Changge for advice.
