My brother Ying Zheng, who dares to kill me?

Ying Chengyu saw Mi Tian's desire for power, so he suddenly gave her a chance.

It's like an open-book exam without advance notice.

You can't prepare for this in advance, but you can find the answer casually during the exam, and you can even ask everyone including the invigilator.

What Ying Chengyu wants to see is Mi Tian's quick wit, communication skills, intelligence gathering ability and ability to control the overall situation!

Mi Tian knew very well that Ying Chengyu was not a person who was blinded by lust.

If Mi Tian cannot satisfy Ying Cheng Yu, then Mi Tian will not get a second chance. No matter how hard she works in this life, she will only be destined to be a enchanting concubine.

But if Mi Tian can exceed Ying Chengyu's expectations, Mi Tian believes that she will definitely get more rights in the future!

Looking at Ying Chengyu's back in the distance, Mi Tian whispered softly with eyes full of light: "Master, I really like you more and more!"

For Mi Tian, ​​this is a banquet that will determine her future life!

But to Ying Chengyu, this was just an ordinary banquet.

If Mi Tian can meet his requirements, he will have an additional helper available in the future.

Even if Mi Tian made a mess at the banquet, who would dare to laugh at him?

The only thing worth worrying about is that after others heard about this, they said that he was an unworthy wife, and then they gave him beautiful concubines.

Therefore, Ying Chengyu only gave Zhang Xun half an hour to quickly complete the handover with Mi Tian.

Ying Chengyu himself left Chang'an Jun's Mansion directly.

"Your Majesty, are you looking for me?"

After hearing the order, Cao Mao and Qi Ai hurried to the river ten miles northeast of Chang'an Jun's Mansion.

Ying Chengqiao smiled and asked: "How is the development of the catapult?"

After the Battle of Wei, all craftsmen who were directly involved in the construction of the catapult, including Cao Mao and Qi Ai, were placed under the name of Ying Chengyu to keep the technology secret.

The only job for these people after they were assigned to Ying Chengyu's name was to continue studying catapults.

Cao Mao immediately replied: "The limit that can be reached at the moment is to throw a stone bullet weighing 150 kilograms 160 feet away."

Ying Chengyu asked unsatisfied: "Can't it be heavier and farther?"

Ying Chengyu didn't know what the best catapult could do.

But in Ying Chengyu’s view, it should be more than that!

Cao Mao's eyes widened and he said, "No!"

"Unless there is more suitable wood!"

Qi Ai quickly added: "Your Majesty, we think that a better catapult needs wood that is more resilient and not easy to break."

"This leads to two solutions."

"The first is to choose a kind of god-given wood, which will be widely planted and cut down to make catapults in the future."

"The second is to find a way to make all, or at least most, widespread wood species more resilient."

"After collective discussion and joint decision-making by craftsmen like us, we believe that the first method is simpler but does not meet the needs of the battle."

"Rather than occupying the capacity of transporting grain and fodder for the soldiers to transport catapults when the battle is about to begin, we craftsmen should study more on weekdays so that the generals can build catapults anywhere when the battle is approaching."

"So we chose the second method and are trying it one by one."

Qi Ai bowed his hands and said sincerely: "It weighs one hundred fifty kilograms and is one hundred sixty feet long. This is our current achievement."

"But I believe that we will be able to develop a better catapult."

"Help Da Qin and help you conquer all directions!"

"Please give us some more confidence and patience, Your Majesty!"

Cao Mao yawned.

He almost fell asleep after listening to such a long list of nonsense!

Ying Chengxiao smiled and nodded: "Very good!"

"I am very satisfied."

Qi Ai hurriedly handed over his hands: "Thank you, Your Majesty!"

While talking, Qi Ai raised his elbow and bumped Cao Mao.

Cao Mao reluctantly bowed his hands and said, "Thank you, Your Majesty."

Ying Chengyu helped Qi Ai and Cao Mao up with both hands, and said seriously: "I am not satisfied with your current research results."

"What makes me even more satisfied is your research attitude and research methods."

"I hope you can put this attitude into any research!"

Qi Ai hurriedly raised his hands and bowed again: "We have made our own decision, but we are all extremely frightened. We are looking forward to the return of Lord Chang'an every day, so I will report this matter."

"Now that Mr. Chang'an has affirmed it, I feel so relieved that the stone has fallen to the ground."

"We must further study this method!"

While speaking, Qi Ai took down Ying Chengyu's instructions in detail.

You are not afraid that your superiors will ask for too much, but you are afraid that your superiors will not ask for anything.

Now that Ying Chengyu has clearly stated his preference, what Qi Ai has to do is to continue to follow Ying Chengyu's wishes!

Cao Mao asked in return: "Chang'an Lord, you have other ideas and you want me to study them?"

Ying Chengyu was a little surprised: "Why do you see it?"

Cao Mao said straightforwardly: "There is no war now, and Lord Chang'an has just returned home, so there is no reason to pay special attention to the catapult."

"Even if Lord Chang'an is concerned about the progress of the catapult, there is no need to call us here."

"Chang'an Jun also talked about the method of studying, so I guess it's not just casual talk."

"As the saying goes, you have nothing to offer...wuwuwu~~~"

The words "To be courteous for nothing is to be either a traitor or a thief" were forcefully slapped back by Qi Ai.

Despite the cold wind, Qi Ai's back was dripping with cold sweat, and he smiled nervously: "Mr. Chang'an, what Master Cao means is..."

Ying Chengyu smiled and waved his hand: "No problem."

"I understand, but I don't care."

"I just hope that his head is worthy of his uprightness!"

Ying Chengyu had heard too many stories about scientific geeks in his previous life, and he would never pretend to be a prince.

As long as Cao Mao's talents can be used by Ying Chengyu, Ying Chengyu doesn't care about Cao Mao's collision.

However, Qi Ai was even more panicked.

What if Cao Mao's head is not worthy of his uprightness?

Is it possible that Cao Mao's head needs to be moved? !

Qi Ai quickly made up for it tactfully: "Everyone has his own way of doing good."

"Master Cao is better at metallurgy, but because of his ability to understand by analogy, he is competent in the study of catapults."

"I wonder what Chang'an Jun is thinking about this time?"

"We and all of us must do our best to be used by Lord Chang'an!"

Ying Chengyu understood Qi Ai's subtext, but had no intention of responding. Instead, he directly expressed his request: "I want to educate talented people."

"Master, I can find all the classics and books."

"However, I also need a writing material that is cheap, wear-resistant, widely available, simple to manufacture, and easy to transport, so as to reduce the waste between teaching and learning."

Cao Mao muttered in a low voice: "I want it too!"

As a master craftsman, Cao Mao often needed to write memorials.

If the writing materials envisioned by Ying Chengyu really appear, then Cao Mao will also be the winner.

But is this something that can be obtained just by thinking about it?

We can’t figure it out!

Ying Chengyu ignored Cao Mao's complaints and continued: "I have several ideas about this thing."

Cao Mao suddenly looked at Ying Chengyu and asked in surprise: "Mr. Chang'an already has an idea?"

If someone else said that he had an idea, Cao Mao would spit in his face, and then ask him to go back and read "Mozi" with disdain before talking about it.

But when Ying Chengyu said this, Cao Mao immediately chose to believe it!

In Cao Mao's view, Ying Chengyu, who could build a catapult, was at least half a master craftsman.

The method proposed by Ying Chengxuan is definitely worth a try. Even if it doesn't succeed in the end, you can at least accumulate a lot of experience!

Ying Chengqiao smiled and nodded: "It's just an idea."

“If we want to realize this, we still need your help.”

Cao Mao immediately rolled up his sleeves and said energetically: "Just give me your orders, Lord Chang'an!"

Ying Chengyu did not express his thoughts directly, but tugged on his clothes: "Today's orders are all written on silk paper."

"Why can ink fall off silk paper?"

Cao Mao said without hesitation: "It's because of the paper!"

"The silk with double warp and double weft makes the silk paper fine in warp and weft, making it watertight."

"When ink falls on a piece of silk, the ink will blur and become invisible, so you can write words."

Cao Mao frowned slightly: "Chang'an Lord, don't you intend to study the paper together?"

"To put it bluntly, Rong Beizhi, you..."

Ying Chengyu said directly: "Since it doesn't sound good, then don't say it."

"I am indeed determined to realize my wish on paper!"

Cao Mao:......

The complaints are stuck in your throat like a mouthful of old phlegm, and you won’t be happy if you don’t spit it out!

But looking at the crown on Ying Chengyu's head, Cao Mao could only swallow the old phlegm into his stomach angrily, and said in a low voice: "What you are doing is completely opposite to what you think!"

This sentence is already the nicest sentence Cao Mao can think of!

Qi Ai hurriedly apologized and said, "Don't be weird, Mr. Chang'an. Mr. Cao is just outspoken."

Qi Ai hurriedly helped to find compensation.

But even in the process of making amends, Qi Ai did not say that Cao Mao was wrong.

Because Qi Ai's views are exactly the same as Cao Mao's!

Ying Chengyu shook his head: "I am determined to find a solution in Zhiyi, but I am not in Silk and Zhiyi."

"It's about finding a solution together with Tomashi."

Qi Ai thought thoughtfully: "Thatch paper?"

"How can text be written on thatch paper?"

Silk paper is a top-grade writing material that even Ying Chengyu is reluctant to use frequently. It is a noun.

But thatch refers to the smooth floc of fibers gathered together, which is an adjective.

Although both are called paper, their values ​​are very different!

Ying Chengyu pulled down his clothes again: "A piece of silk with two warps and two wefts can bear the ink."

"However, silk with a single warp and single weft is not convenient for writing, and linen cannot be used for writing."

"What's the explanation?"

"I think it all depends on whether the warp and weft are fine!"

"The weaving technique of double warp and double weft allows the silk thread to be fine and dense."

"But can even the finest latitude and longitude lines be finer than those of thatch paper?"

The corner of Ying Chengyu's mouth curled up slightly, and he said in a deep voice: "So what I want to do is to take silk, hemp, bamboo and hammer it into tarpaulin."

"Then cut out a thin layer of these sheets and dry them in the sun."

"What you get may be enough to meet my needs!"
