Father, this is the architectural drawing of Yong'an Palace, I don't know if my father has any objections. If not, then the minister is ready to start construction. Li Chengqian said after handing over the drawings to Li Shimin.

Li Shimin took the drawings and looked at them, then nodded and said to Li Chengqian: "Generally speaking, I don't have any opinions, you can start construction as soon as possible according to him." ”

After getting Li Shimin's approval, Li Chengqian said to Yan Lide: "Since my father has agreed, then you can start making preparations." ”

Yan Lide nodded, then took his leave and left the Manna Palace. Seeing Yan Lide leave, Li Shimin opened his mouth and asked Li Chengqian: "Say, what is the purpose of the underground ice cellar?" ”

"Sure enough, I can't hide anything from my father, but even if my father doesn't ask, my son will tell my father. The real name of this underground ice cellar is Tiangong Pavilion. ”

Then Li Chengqian told Li Shimin in detail about the usefulness of this Tiangong Pavilion. And told Li Shimin that in the future, there will be many things that will benefit the country and the people from Tiangong Pavilion.

Of course, there will be some weapons that Li Shimin can't imagine. At that time, the Tang army will become the real king of the world.

Li Shimin couldn't help but nod when he heard this, and then asked Li Chengqian: "Although I think these things you said are a little amazing. ”

"But I want to believe you, and I hope you can let me see what you say in my lifetime."

"Father, don't worry, when the time comes, you will definitely let your father drive a car and take the queen mother to travel all over the Tang Dynasty." Li Chengqian said to Li Shimin with confidence.

"I hope you're not painting me a cake. But I have one thing to tell you. There has been news from Youzhou that Lu Wanda, the old man of the Fanyang Lu family, has come to Chang'an City. Li Shimin opened his mouth and said to Li Chengqian.

"Erchen is still afraid that he won't come, as long as he comes, the rest of the things will be much easier." Li Chengqian said with a smile on his face.

"You're a troublemaker. I don't know if it's a blessing or a curse to encourage you like this. Li Shimin shook his head and said.

……

"His Royal Highness the Prince, the grass folk are performing quite well." Gao Jin in the hero building said to Li Chengqian with a smile.

"You did a very good job. It's just that Hongu has something to ask you. How can you be sure that Wang Fugui will shake out ten sixes? Li Shimin opened his mouth and asked Gao Jin.

"Even if the king's shopkeeper can't fold up a dice, he must win in the end." Gao Jin said to Li Chengqian with a smile.

This couldn't help but make Li Chengqian feel strange, so he said to Gao Jin: "It seems that you must have some way, why don't you talk to this palace today." ”

Gao Jin nodded, and then asked someone to fetch a color cup and ten dice. performed again in front of Li Shimin.

This time, Gao Jin's movements were very slow, and Li Chengqian could see the whole process. It's okay not to look at it, this look made Li Chengqian couldn't help but be surprised.

Even the eldest grandson Chong on the side shouted, it turned out that after Gao Jin opened the color cup, he could also make the number of points of the color change with his thoughts.

Looking at the surprised faces of Li Chengqian and Eldest Sun Chong, Gao Jin opened his mouth and said, "I don't know if His Royal Highness the Crown Prince has heard of the Yin Yang Puppet Technique. ”

This yin and yang puppet technique is no stranger to Li Chengqian, it is said to be a magical technique invented by Zou Zi, the ancestor of the Yin and Yang family in the Spring and Autumn Period.

So Li Chengqian nodded, and then said to Gao Jin: "The Yin-Yang puppet technique should be the technique of the Yin-Yang family, but the Yin-Yang family has long disappeared. I don't know where you got this yin-yang puppetry? ”

"His Royal Highness the Crown Prince doesn't know anything, his mother's surname is Zou. The ancestor of the mother of the family is the ancestor of the Yin and Yang family. And the Yin and Yang puppet technique that the grass people know is also the secret method of the Yin and Yang family. Gao Jin said to Li Chengqian.

Li Chengqian didn't expect that this Gao Jin would be the heir of the Yin and Yang family. This was indeed a bit surprising to Li Chengqian.

So he opened his mouth and asked Gao Jin: "As far as this palace knows, this yin and yang puppet technique needs to use a mechanism. But this palace has seen that this color cup does not have any mechanism. ”

When Gao Jin heard Li Chengqian's words, he stretched out his right hand. Looking at the sun, Li Chengqian unexpectedly found that there were thin silk threads on Gao Jin's fingers. And Gao Jin uses these silk threads to control the dice.

After revealing the silk thread on his fingers to Li Chengqian, Gao Jindian said: "If His Royal Highness the Crown Prince does not dislike the humility of the grass people, the grass people are willing to serve the prince." ”

"Naturally, this palace can't ask for a person like you, but this palace wants to know what your ambition is." Li Chengqian opened his mouth and asked Gao Jin.

"To tell the truth, the grass people hope that the Yin and Yang family will no longer be silent. Although I don't expect to regain the prestige of the hundred schools of thought back then. At the very least, I hope to make him a doctrine recognized by the world. Gao Jin said to Li Chengqian.

Li Chengqian nodded after hearing this, and then said to Gao Jin: "If you want to make the Yin and Yang Family regain its glory, it depends on how capable you are. ”

"If you use the Yin Yang Puppet Technique to control the gambling equipment, you will at best show off your power in this Hero Building."

"Your Royal Highness the Prince, today the grass people have a gift for His Royal Highness the Prince. After reading it, His Royal Highness the Crown Prince will understand whether the grass people should be limited to this hero building. After Gao Jin finished speaking, he took out a wooden box from under his feet.

and placed the wooden box directly in front of Li Chengqian. I saw that this wooden box was painted with a yin and yang map, and the five elements of gossip were carved around it.

It looks like the whole box is so integrated that it even makes people think it's just a wooden block. It's not a box at all.

Gao Jin, on the other hand, kept beating on the wooden box with his hands, and the position of each knock was different. There is also a difference in the severity and frequency.

Soon the sound of machinery came out of the wooden box, and then the whole wooden box began to slowly change. In the end, it was completely opened in front of Li Chengqian.

At this time, what appeared in front of Li Chengqian was no longer a wooden box, but something that looked like a chessboard. And there are also pieces on the chessboard that resemble chess pieces.

This couldn't help but make Li Chengqian feel strange, although the scene just now really shocked Li Chengqian. If it's just a chessboard in the end, it's a bit flashy.

And Gao Jin naturally saw Li Chengqian's thoughts. So he pressed the mechanism on one end of the board. At this time, I was watching, and the chess pieces on the chessboard actually moved automatically.

Looking at the chess pieces that were moving regularly, Li Chengqian couldn't help but be interested. Then he opened his mouth and asked Gao Jin, "What is this thing for?" ”

"I wonder if His Royal Highness the Crown Prince has heard of the Eight Array Diagram?" Gao Jin opened his mouth and asked Li Chengqian.
