The villain prince is three and a half years old

[Blank Design Drawing - Large: This drawing contains advanced technology. Upon use, you can obtain technical information. Due to drawing limitations, complex information cannot be obtained.]

It's useful, but not particularly useful. It fits the "Wish Paper Crane - Pink" positioning perfectly.

This blank blueprint is the related prop of the technology tree that will be opened in the later stage of the game.

Using this blueprint, you can obtain technology for civilian or even marginal military use.

Don't be fooled by the suffix "Big". In fact, just like milk tea only has medium and large cups but no small cups, this blueprint only has two levels, Big and Super. Only the super-quality design can produce important military technology.

After returning to Jingyixuan and washing up, Xia Jing sat on the edge of the bed, holding paper, pen and ink, to make a blank design drawing.

He froze as he picked up the pen.

The blank design drawings in the game are not blank. The moment they appear, relevant technical knowledge is recorded on them.

He tried to cut the paper into the appropriate size, left the paper blank, and clicked to extract the design drawing, but it failed.

The technical information must be written on it.

But I have already written down the technical data, so why do I need this design drawing?

Xia Jing was in a trance and saw two little men fighting.

Villain A: How can I obtain advanced technical information?

Villain B: Use the blueprint!

Villain A: But to extract the design drawings, you need to write down the advanced technical information!

Villain B: Go get advanced technical information!

Villain A: Do you want to see what my first question is?

The fist is hard.

Xia Jing pondered for a moment and found that there were loopholes.

Although the design drawings record advanced technical information, it is not complete. It is just a thumbnail with only a few formulas and patterns.

That is to say, if you want to, you only need to write down a small part to complete it!

Xia Jing wrote with a big stroke of his brush.

"One nitrate, two sulfur, three charcoal"

extract!

[Beyond the scope of use of the design drawing; insufficient information]

This is the formula for black powder, a military technology. This design can only be used for civilian purposes.

He changed a piece of paper and drew the cement manufacturing process. He had only seen the process.

[Beyond the scope of use of the design drawing]

Tsk, this is beyond the limit. However, the information is sufficient.

Having given up on gunpowder and cement, Xia Jing thought about where they could be used.

It seems that the glass is the only thing left now.

Xia Jing wrote down his own glass-making method.

[Insufficient information]

He had seen and handled cement, but glass and gunpowder were pure clouds, so it was normal that there was insufficient information.

I'll go to Ning Zhixing's glass workshop tomorrow and secretly copy the glass-making process. That should be enough.

Putting down the paper and pen, Xia Jing lay down in bed.

Now it's time to go to bed.

……

Just in case, the first thing Xia Jing did when he got up in the morning was to ask Xiao Yue to take a sick leave for him.

In this way, even if Emperor Kang Ning is still upset today and wants to go to the study to teach, he won't be able to cause trouble for him.

Emperor Kangning wouldn't come to Jingyixuan to see him, right?

Every move of the emperor, whether or not it carries a hidden meaning, will be interpreted with deep meaning by the court and the public.

It’s just like the stock speculation method that was popular on the Internet in the past: read the official news, and buy stocks of the group that the leader visits, and you will definitely make a profit.

Ancient officials also used this method to speculate on political trends.

Emperor Kangning was an extremely rational emperor. He would definitely not come to see the prince just because he had asked for leave.

"It's okay to take a leave today." Yi Qiu wiped Xia Jing's face. "I heard that the prince and princess of Yan will enter the palace this afternoon. Tomorrow, the prince of Yan will go to the upper study to study. Young master, you should rest up today and go to the upper study tomorrow to take a look."

"Princess?" Xia Jing was stunned.

He didn't pay much attention to the Yan hostage issue, so how come a Yan princess suddenly appeared?

"I heard that the emperor originally wanted another prince, but Yan State refused, so he sent a pair of siblings here." Yi Qiu explained.

"Oh." Xia Jing responded calmly. Whether it was just one person or a couple, it made no difference.

After breakfast, he went straight to the glass workshop of the craftsman supervisor.

With the support of the Cining Palace, Ning Zhixing did not hesitate to embezzle more resources from the Supervisor of Craftsmen. Even some projects that the concubines had entrusted to the Supervisor of Craftsmen were stopped, and all the funds and materials were taken away.

Ning Zhixing took out a piece of glass and handed it to Xia Jing: "This is the only successful furnace, and it will be impossible to reproduce it when firing again."

Xia Jing took the glass. The transparency was acceptable, though a little blurry. However, the crack in the middle...

"There was no bump on it, it cracked by itself." Ning Zhixing explained.

Even successful products that are the result of a burst of luck are not successful.

"How long will it take to figure it out?" Xia Jing put down the glass and asked Ning Zhixing.

If he had less time, he wouldn't have needed to draw up the blueprints.

"Maybe two or three years, maybe even longer." Ning Zhixing estimated.

Now, apart from finding the main raw materials, I have no idea about anything else.

Xia Jing nodded. Two or three years was too long. He needed Ning Zhixing to research other things and didn't have the time to wait.

"I'll go and take a look." Xia Jing said.

He walked around the workshop, learned about the glass technology, and carefully asked Ning Zhixing about the relevant technical points.

Finally, he found a pen and paper and put the steps together. He changed four sheets of paper and tried four times before finally completing the design.

【Glass technology and derived design drawings】

Wow, there are actually derivatives.

Moreover, the blank design drawings in the game are randomly produced technologies. Xia Jing filled in the glass technology and selected glass in a targeted manner, turning a random project into a controllable project.

Once you get a higher-level design, you can directly invent a musket.

However, there must be a general technical procedure first. Just like glass, a workshop must be built first and preliminary research must be completed.

This initial part still depends on Ning Zhixing.

Xia Jing used the design drawing, which lit up and then went out.

As usual, technical information will appear in dreams.

Xia Jing found a clean table, lay down on it and started to sleep.

My consciousness was pulled away from reality and I entered a spacious space where a large bookshelf was half filled with drawings.

The total amount of those drawings is higher than that of the Ninth Prince.

Xia Jing felt something was wrong. He picked up a blueprint and slapped it against his forehead.

The drawing remained unchanged, the ink words and patterns were still there, but they did not enter his mind.

It's over.

The Ninth Prince was heartbroken. This crappy game, what kind of dream scene? Couldn't it just be played directly in his head? With so many drawings, how long would he have to wait to see them?

You can skip classes in reality, but how can you skip classes in dreams?

How about letting the fourth brother study it for two or three years?

Xia Jing sighed and picked up the drawing.

I have used them all.

Come here.

I've seen them all.

……

The Ninth Prince slept until noon and was awakened by the smell of lunch.

He wiped the corner of his mouth and sat down next to Ning Zhixing.

"What delicious food did you dream about? You kept smacking your lips." Ning Zhixing asked the eunuch to add more bowls and chopsticks.

This was the room where he rested and drew blueprints. In his free time, he observed the sleeping Ninth Prince.

"It's something sweet, bitter, hateful, and yet hard to let go." Xia Jing took the bowl and chopsticks.

Xia Jing thought, that was not a dream about delicious food, but a dream of drowning in the ocean of knowledge, in Aba Aba.

However, fortunately, there were some gains.

Letting Rendong feed him, Xia Jing took out a pen and paper and solved the current problem - the materials were impure.

Fortunately, he entered the study, otherwise there would be no explanation for how he could write.

"I went to Third Brother's yard to play with sand and found that in the large tank containing skinks, in addition to yellow sand, there were also white gravel-like things. Fourth Brother's materials may have been mixed with unnecessary things."

Xia Jing drew and marked a set of filtering solutions.

Ning Zhixing took the drawing and nodded.

It turns out that the big vat in Ning Shouxu's yard was used for playing with sand. That bastard actually lied to him and said he had a little pet!

He retracted his scattered thoughts, looked at the blueprint in his hand, and recalled Xia Jing's explanation. Suddenly, he felt that many things had been explained, not just the glass, but also the problems he encountered elsewhere.

He recalled the time when he successfully fired glass. That batch of raw materials was piled up by the craftsman supervisor and had been stored for a long time. Perhaps it was during the stacking process that the filtration was completed by coincidence.

He looked at Xia Jing's little head.

This angle isn't subtle, it's just hard for others to realize. I really don't know where this guy gets so many strange yet correct ideas.

He reached out and touched Xia Jing's head.

"Fourth brother, what are you thinking about?" Xia Jing shuddered. Ning Zhixing had a blank expression on his face, staring straight at his head, and his hand stroking him was very gentle, which was frightening.

He covered his head and advised Ning Zhixing to give up the dangerous idea: "The head replacement surgery in the myth is impossible to succeed! Not to mention anything else, the blood vessels can't be sewn up!"

He suspected that Ning Zhixing was after his head.

Blood vessels? Ning Zhixing didn't know what the word meant, but he thought it was quite interesting.

"What are blood vessels?" he asked.

Xia Jing used the veins on Ning Zhixing's hand as an example. In that era, dissecting animals, let alone corpses, was considered a criminal offense, leading to arrest. Therefore, ancient people had little understanding of the human body's interior.

Ning Zhixing's first reaction was that it was absurd, but after thinking about it carefully, he felt that it made sense.

He originally thought that the human body was a mysterious thing consisting of meridians, acupuncture points, the five elements of qi and blood. Now he feels that the human body is similar to carpentry, both have clear combination plans, and can be explained by visible things.

Ning Zhixing thought, "Once I've made the glass, maybe I can ask the doctors at the Imperial Hospital for advice."

Xia Jing didn't know what impact he had on Ning Zhixing, and he wouldn't care even if he knew. If Ning Zhixing were to become the beginning of modern medicine, that would be great.

As long as he doesn't stare at the Ninth Prince's head with such eager eyes.

After lunch, Xia Jing left the Craftsmen's Supervisor and quickly headed to Jingyixuan.

Although he felt that Emperor Kangning would not go to Jingyixuan to find him, the Ninth Prince, who had been caught by Emperor Kangning three times, had a psychological trauma.

As he approached Jingyixuan, he glanced at the 3D map and found that there was no icon of Emperor Kangning, so he felt relieved.

He lifted his foot to step over the threshold, but then realized something was wrong.

There is no icon for Emperor Kangning, so why is there an icon for Wen Daosheng?
