"Wei Chen understands." Wang Ning'an said helplessly.

Li Yuan had nothing to say this time. Since it was very helpful in fighting wars, it would be better not to use it among the people. It would be best if it was controlled by the imperial court.

He admired Wang Ning'an even more, knowing that such an important thing could not be leaked, so he asked Li Tai to make it, so that the craftsmanship was still in the hands of the court and the royal family.

Li Er said in a deep voice again: "Wang Ning'an, I know about the cultivation of food, but I have never heard you talk about the production of glass. Do you have the finished product?"

"Your Majesty, this is the private property of a humble minister." Wang Ning'an couldn't help but say.

"Hmph, do you think I will miss that little thing of yours?" Li Er couldn't help snorting coldly. This kid is so annoying. He thinks of me as nothing.

Wang Ning'an said: "Your Majesty, after a while, Wei Chen will hold an auction. Your Majesty, all ministers, Hu merchants and businessmen from the Tang Dynasty will be invited to attend the auction. Wei Chen will sell some glass products.

, and some good stuff.”

"Okay, since you are prepared, I will wait and see." Li Er said.

Then he looked at the Datang Divine Wing and said: "What are you going to do with this Datang Divine Wing? This thing is not allowed to appear among the people."

"Father, please leave the Divine Wings to your son to handle." Li Chengqian said.

"You will handle it?" Li Er looked at his son with interest and asked, "What are you going to do?"

The eldest grandson said in a deep voice: "Ascending Qian, don't mess around."

"Mother, I am not messing around." Li Chengqian explained: "Wang Ning'an just said that the Divine Wings of the Tang Dynasty combined with telescopes are the best equipment for detecting the enemy's situation. I will use these Divine Wings to train a Divine Wing team to specifically detect the enemy's situation.

.”

Changsun nodded with satisfaction, but still did not lose face and said something useful.

Wang Ning'an said: "No, Prince, this matter is not feasible for the time being. The Datang Divine Wing has just been developed. Although Wei Chen personally tested it once, it is quite safe.

But it does not mean that it will be safe the second time, the third time, or the tenth time. Just in case, Weichen suggested producing a hundred Datang Divine Wings first and giving them to Weichen for testing.

Weichen will find a dedicated person to test it, and make records every time it flies, so that we can know if there is anything that can be improved. Then we will make the safest divine wing and then train the army. This will be better."

Li Er nodded: "Just follow Wang Ning'an's method, Prince, you will help from the side. Ke'er, you will complete the construction of the academy by yourself."

"My son, I will definitely live up to my father's hopes."

"Well, that's it. Let's keep this divine wing. Tomorrow, let the Ministry of Industry make another hundred divine wings and send them to the Prince's Mansion. Ning'an, you can go to the Prince's Mansion to get them." Li Er said.

"It's Your Majesty (Father)."

"Let's all go back."

"Your Majesty (Wei Chen) retires."

Li Yuan spoke at this time: "Ning'an, please stay and talk to me."

Wang Ning'an couldn't help but stop and look at Li Er and Li Yuan.

Li Er said angrily: "You can stay as long as the Emperor asks you to."

"Yes, Your Majesty."

Wang Ning'an followed Li Yuan to his palace.

"Your Majesty, why did you ask me to come?" Wang Ning'an asked.

Li Yuan smiled and said: "I have been alone in the palace for a long time and I am very bored. I want to find you to relieve my fatigue. Do you think there is anything in Neo-Confucianism that can pass the time?"

"To kill time?" Wang Ning'an raised his head and thought for a moment. In his previous life, the best way to kill time was to play games online, and the day passed like this.

But what can we play now that we have no electricity and no computer?

Ding dong.

A light lit up in the upper left corner of Wang Ning'an. He came up with an idea and said, "Your Majesty, do you like playing chess?"

"Aren't you going to teach me, an old man, how to play chess?" Li Yuan said with a bitter smile.

Wang Ning'an immediately said: "Yes, Wei Chen taught the Supreme Emperor not to play Go, but to play chess. Please ask the Supreme Emperor to give me paper and pen."

"Here, bring a pen and paper."

A eunuch immediately brought a pen and paper and handed it to Wang Ning'an.

Wang Ning'an immediately picked up the pen and began to draw on the paper. While drawing, he said: "Your Majesty, what I teach you is called chess. It divides red squares and black squares. It is a kind of confrontational game between two people. What I am drawing now is a chessboard.

This is the river boundary, also known as the "Chu River-Han boundary", which means the conflict between Chu and Han.

The red side uses a general to control the officials, and the two ministers, two men, two cannons, and five pawns; the black side uses a general to control the soldiers, two elephants, two chariots, horses, cannons, and five pawns. During the game, both sides take turns to play chess, with "

Checkmate" or "trapped to death" means the opponent's general (handsome) wins.

In addition, the walking methods of each profession are also different. Soldiers can only walk forward or sideways, and cannot go backwards. They can only walk sideways after crossing the river, and horses..."

Wang Ning'an explained the rules of chess nonstop, which captured Li Yuan's curiosity.

After the painting was completed, Wang Ning'an said again: "Your Majesty, please send people to the Ministry of Industry and ask them to quickly make the chessboard and chess pieces out of wood."

Li Yuan immediately said to the eunuch beside him: "Did you hear that? Go and do it quickly. When will it be done, when will you come back?"

"yes."

The eunuch quickly took the paper of Wang Ning'an's painting to the Ministry of Works.

On the other side, Changsun told Li Er about Wang Ning'an.

"Is the second brother worried about not being able to control Wang Ning'an?" Changsun asked.

Li Er nodded slightly and said: "You are right, I am now very afraid that he will leave without saying goodbye like Taoist Yunyou, leaving me unable to find him no matter how hard I look.

At the same time, I am afraid that he will not be under my control, so I can't help but want to destroy him."

Changsun smiled and said: "The second brother would be reluctant to part with such a good talent."

"You are right, I am very reluctant to let go." Li Er sighed helplessly. Wang Ning'an's performance was getting better and better, which made him happy and scared at the same time. He was really afraid of losing such a good talent.

"Guanyin Maid, is there anything you can do?"

Changsun smiled and said: "I heard that Wang Ning'an is already fifteen, and it is time for a man who is fifteen according to the Tang Dynasty law to get married."

Li Er's eyes lit up and he said: "You are right, it's time to get married. The wandering Taoist is just because he is alone and can leave at will, but after he has a family, he cannot leave.

But whose girl should I find better?"

Li Er was troubled by this matter again.

Changsun chuckled and said: "Second brother, you are really confused. Who has Wang Ning'an been closest to recently?"

"Who?" Li Er was a little confused.

"Hey, you men are just careless. After all, you are also a father. You don't even know who your daughter has been with recently." The eldest grandson said angrily.

"Xiangcheng?" Li Er suddenly thought that Wang Ning'an and Li Xiangcheng have been going in and out recently and were inseparable. I'm afraid no one would believe them if they said they were not related.

He patted his head and said with a wry smile: "Mr. Guanyin is still thoughtful. I'll leave this matter to Miao Guanyin. But we can't be allowed to speak. I'll find a way to make that kid speak first."

Changsun thought for a while and said, "I have already thought of a way." Then he began to whisper in Li Er's ear.

Li Er listened and nodded with a smile and said: "My Guanyin servant is still smart, but the two of them will have to suffer a little."

The eldest grandson smiled and said: "Second brother, this is called a friend in need, and that's how we got here."

"Haha, that's right. A friend in need is a friend indeed, and a friend in need is a friend indeed, haha..." Li Er laughed heartily, then blocked the eldest grandson's mouth with his mouth and pressed her down.

Wang Ning'an didn't know that he was being plotted by Li Er and Chang Sun, so he and Li Yuan started playing chess with pieces of paper instead of chess pieces.

"No, no, I don't want to take this man." Li Yuan was like a child, wanting to regret the move.

Wang Ning'an said dissatisfiedly: "Your Majesty, you have already regretted fifteen moves. I don't want you to play like this."

"No matter, no matter, I don't care. I just want to regret my move." Li Yuan immediately acted like a rogue.

Wang Ning'an said helplessly: "Okay, okay, you regret it, you regret it."

Li Yuan immediately smiled brightly and said: "Okay, I'll go out." He took the black general one step forward.

Wang Ning'an moved his chariot forward and said with a proud smile: "Your Majesty, your Majesty, you can't cheat this time. No matter which way you go, you will be killed."

Li Yuan held the piece of paper in his hand and moved it left and right, all of which were fatal moves. Just when he was about to give up, the eunuch who went to the Ministry of Works came back.
Chapter completed!
