The Supreme Prosecutor of the Tang Dynasty

"Is this question difficult?"

Chen Qiu asked himself, if he was given time, it would not be too difficult to solve this problem!

Road construction?

Easy!

Have you heard of cement? Have you heard of asphalt?

If I find asphalt mines, I can even build asphalt roads. This kind of road, which is still widely used even in modern times, is smooth and durable!

Even if you give me enough time, I can even come up with railways and trains!

A train can transport thousands or tens of thousands of people at a time People are not a problem, and you don’t need to rest when you travel thousands of miles a day. Even if it only takes a day or two from Chang’an to the border, are you afraid??

Send messages?

Have you heard of mobile phones? Even if you are on the other side of the world, you can Can make instant calls instantly!

Of course, mobile phones are too advanced for the current Datang Dynasty. If we really want to do this, even if we start preparing now, it will take at least many years of research to succeed. It can't be done overnight.

Trains also take a lot of time. Among them, the shortest time consuming is probably cement. However, it also takes time. At least, if you want to do it overnight, it is not that simple.

"Forget it, let’s not scare them by telling them about cement, asphalt, gunpowder, etc. We’ll talk about it later when we get the cement out."

"As for trains and mobile phones, telling them these now is not a waste of time. I’m afraid everyone will think I’m just bragging, right?"

"However, if you want to send messages more quickly, it is not impossible.……"

"After all, in addition to sending troops to hurry up and rush for eight hundred miles, conveying a message can also be……"

"Flying pigeons pass messages!"

In the Spring and Autumn Period and the Warring States Period, there were already pigeons with different looks in the south of the Celestial Dynasty. During the Qin and Han Dynasties, the court and the people were obsessed with the raising and management of various pigeons.

During the Sui and Tang Dynasties, pigeons were used for communication in Guangzhou and other places in southern China. , Chinese and foreign working people at sea have used pigeons to deliver letters to their families to report that they are safe.

According to Chen Qiu’s understanding, the appearance of flying pigeons to deliver letters in the Celestial Dynasty should have happened around the early and mid-Tang Dynasty...

Now, it is the Tang Dynasty Early stage ~

In other words, Fei Ge Chuan Shu appeared in the next few years. Perhaps it was because of Li Er's current confusion that the Fei Ge Chuan Shu appeared later!

Who is Fei Ge Chuan Shu? There is no accurate record of the invention, but...since Chen Qiu has traveled through time, then he invented the flying pigeon to pass messages!

Ahem, credit, don't give it up in vain!

Moreover, Chen Qiu is about to ask for it. It takes some credit to bring Wu Zetian into his pocket.~

"His Majesty! Chen

Qiu took a step forward and said,"There is no rush to build the road for now. I will have a better way later. As for sending the message!""

"Sir, there is a plan you can try!"

"Chen Aiqing, say it quickly!"

Li Er was instantly refreshed, and the entanglement and anguish on his face were reduced a lot!

In fact, Li Er himself had never noticed that in his heart, he had vaguely felt, or tacitly believed, who would be the most powerful person above the court? If it is possible to solve this problem, then this person must be Chen Qiu!

"If you want to send messages quickly, what you need is undoubtedly speed!"

Chen Qiu spoke calmly, but what he said made Li Er and Manchao Wenwu all stare in shock.

"People or horses can only run on the ground. No matter how fast the speed is, there is a limit!"

"In addition, fatigue, hunger, etc. will all become obstacles that limit the transmission speed. Therefore, even if the road is repaired, the speed will not be much faster!"

"Therefore, if you want to send messages quickly, you can't run on the ground!"

"Not running on the ground? Wei Zheng was stunned for a moment, then sneered:"Master Chen is really good at joking. If you don't run on the ground, how can you fly in the sky?""

"Could it be that we need to give the letter a pair of wings?"

As soon as these words came out, most of the civil and military officials felt uncomfortable.

Many people wanted to laugh. After all, it was really ridiculous to give wings to letters or something, but they didn't dare to laugh.

Who dares to laugh at Chen Qiu? He doesn't want to live. Is that so?

Only Wei Zheng, an old guy who has no fear of heaven and earth, and a tough life, dares to chat with Chen Qiu, even tit for tat...

Others?

Even Changsun Wuji, the second among the 24 heroes of Lingyan Pavilion, ranks second The boss is also very jealous of Chen Qiu. If possible, he will try not to provoke him.

"Unexpectedly, Mr. Wei is quite smart and would think of giving a pair of wings to Xin?"

Chen Qiu grinned……

"Hahaha, no, no, I was just teasing. A letter with wings is just a letter. Can it still fly?"

"After all, a letter is just a dead thing and must be carried by a messenger or a messenger before it can be moved!"

"In myths and legends, those gods can fly. Unfortunately, we are all ordinary people, how can we not walk on the ground?"

"Mr. Chen, aren’t your words a joke?"

Wei Zheng rolled his eyes. Although he didn't press forward step by step, he was still aggressive.

"Hahaha……"

Chen Qiu bared his teeth and said,"Mr. Wei, actually, I was really joking."

"After all, I am not you. My eyesight is dim and my brain is not very bright. I can think of such a stupid way to give a pair of wings to a letter.……"

Wei Zheng:"……"

"What did you say! ?"

[○｀Д○]!!!

Am I so angry?

Wei Zheng was so angry that he puffed his beard and glared, and said angrily:"Okay, tell me then! I want to see what you can do to make Xin fly in the sky without going overland???"

"Of course, the letter cannot fly."

Chen Qiu glanced at Wei Zheng lightly, then looked at Li Er and said seriously:"Humans can't fly!"

"But who said that people must be used to convey messages?"

"Chen Aiqing means……？"

Li Er was stunned for a while, and all the civil and military officials looked at each other, speechless and choked.

No one is needed to deliver the message? What can no one use? Could it be possible to use ghosts?

Besides, we haven’t seen any ghosts before!

Moreover, how can you really let your love letters fly in the sky? Isn’t this nonsense? Letters can fly, right? ? ?

Some people even wanted to shout, if letters could fly in the sky, I would eat them!

Seeing everyone's shocked and confused expressions, Chen Qiu slowly shook his head and said with a smile:"People can't fly, and neither can letters.""

"However, faith is so light, and there are so many animals that can fly.……"

"Why can't we use birds to deliver letters?"

"How does the speed of a flying bird compare to that of a horse?"

"I guess no matter what, birds are faster than horses, right?"
