When Li Shimin had not ascended the throne and was still the King of Qin, the eighteen scholars of the Qin Palace were all Li Shimin's confidants, but since he ascended the throne, many people have been dormant.

They did not show up in the court. Even though they were all dormant, except for military generals, all the civil officials in the court were still the group of people Li Shimin relied on the most.

Some people have left, some have passed away.

Fang Xuanling, the 18th scholar of the Qin Palace, and some of Du Ruhui, were still in the court.

Among the eighteen bachelors in the Qin Prince’s Mansion, Yu Shinan, who just retired last year, is one of them.

Li Shimin took out a memorial from Yu Shinan, "This is what Yu Shinan gave to me before leaving."

Zhang Gongjin took the memorial and looked carefully and said, "Your Majesty, Yu Shinan has been studying calligraphy all his life. He is more accurate in his words than people."

Li Shimin nodded and said, "Then do you think Yu Shinan is right?"

"Yu Shinan said that Li Zheng is very arrogant in his heart, and this boy needs to be tempered to recover." Zhang Gongjin thought for a while and said again: "In my opinion, Li Zheng is not easy to figure out. He doesn't want power or fame and fortune, but all he wants is money."

Li Shimin drank tea and said, "You continue."

"Here." Zhang Gongjin continued: "The conflict between Your Majesty and Li Zheng is here. There are many strange people in this world, and many strange people have strange temperaments. People who have always loved money can't do anything big."

Seeing that Li Shimin was about to speak, Zhang Gongjin continued, "Your Majesty, let me finish my words. If Li Zheng makes everyone in the world think that he only has money in his heart, he is not a fool but an extremely smart person. If Li Zheng does not give up money, then Li Zheng is nothing to worry about His Majesty being just a fat sheep waiting to be slaughtered."

"Fat Sheep?"

Zhang Gongjin nodded, "Yes."

Li Shimin smiled, "You are really..."

Zhang Gongjin bowed and said, "Although it is not pleasant, it is true. As for whether Li Zheng will become His Majesty's fat sheep, it depends on his own luck."

The king and his subject smiled knowingly.

Li Shimin poured Zhang Gongjin a cup of tea, "How long has it been since you, my monarch and ministers said like this? I still need you to take good care of my illness."

"It's worrying to Your Majesty." Zhang Gongjin whispered.

Li Shimin watched him drink the warm tea and said, "Chaoji warriors will go to Chang'an tomorrow. How do you think you should place them when he returns to Chang'an?"

During the Yuan Dynasty, the envoys from all states would return to Chang'an to report on the situation of patrolling the states. This is the work of the envoys of the dynasty.

After hearing Li Shimin's words, he was quiet for a while.

"I think it's not too high, nor too low." Zhang Gongjin coughed after saying that.

Li Shimin patted his back and helped him breathe smoothly.

"I'm rude." Zhang Gongjin bowed and bowed.

Li Shimin looked at his face and said with a sad face: "Go back to rest early and take good care of your illness."

When Zhang Gongjin walked out of the Ganlu Palace, Li Shimin could hear his coughing outside the hall.

After returning from Yinshan, Zhang Gongjin fell ill and the Imperial Medical Department has been taking care of him carefully.

Li Shimin sighed in his heart that there are still a few left in the 18th bachelor of Qin Wangfu back then.

Yan Liben didn't sleep all day and night, but left the Ministry of Works and went to Jingyang.

Li Yifu walked to Li Zheng and said, "County Marquis, Yan Liben is here again."

"Have he unlocked Luban's lock?"

"No."

"No." Li Zheng said decisively.

In just a few words, Yan Liben refused.

Yan Liben stood at the entrance of Jingyang Village and looked anxious, "How is it? Has the county Houken met me?"

Li Yifu came back and sighed and said, "The county marquis said he would not see you."

Yan Liben gritted his teeth and stomped his feet and said, "If Li Zheng doesn't see me, I will not leave."

Seeing Yan Liben's attitude, Li Yifu had no choice but to let him go.

It was late at night that Daniu helped Li Zheng remove the last tank of petals from the distiller.

"Teacher, that guy is still staying outside the village."

"Which guy?"

"It's the person who gave the Rubik's Cube before, named Yan Liben."

"He's still outside?"

"Yes." The big bull nodded.

Li Zheng slapped his forehead, and the ancients were really stubborn.

"Big bull, bring people."

"good."

The big cow went to the entrance of the village with a lantern.

Seeing Yan Liben coming, this guy looked decadent and had heavy dark circles under his eyes.

Li Zheng looked at his expression and said, "Yan Dajiang, why are you doing this?"

Yan Liben took out the Luban lock and said, "How to solve it?"

Walk the various planes of Luban lock in your mind, and then write down the order, it is actually easy to untie it.

Li Zheng said to Daniu: "Daniu, come on."

"good."

The big bull took the Luban lock.

"You can solve it?" Yan Liben looked at Daniu with incredible eyes. This was a ten-year-old child.

Li Zheng took out a simmered sweet potato from the brazier and handed it to Yan Liben and said, "Actually, the most test of this is geometric thinking."

"Geometric thinking? I have never heard of this skill."

"This is actually a math problem."

"Mathematics is mathematics?" Yan Liben gnawed sweet potatoes and kept staring at the movements of the big bull. The child had dismantled four pieces of wood.

After the big bull pulled out the sixth item, Yan Liben roughly saw some clues.

With the dismantling of the big bull, Yan Liben's speed of eating sweet potatoes also accelerated.

When the big bull pulled out the top wooden strip, the entire Luban lock disintegrated and scattered on the table.

"Is this untied?" Yan Liben swallowed a mouthful of sweet potatoes hard.

The big bull grinned and said, "Actually, this is what we installed."

After saying that, Daniu took out a bunch of drawings and said, "This is the after-class homework given to us by the teacher."

Yan Liben looked at the drawings and looked at Li Zheng again, and he couldn't speak for a long time.

"You go back to bed first." Li Zheng said to Daniu.

Daniu stood up and said, "The student slept with Dahu tonight."

Dahu is a few years older, but the two children get along well.

Li Zheng said to Yan Liben: "With this drawing, I believe Yan Dajiang can reassemble the Luban lock."

"It's certainly no problem to have the drawings." Yan Liben said excitedly: "This is a long-lost craft, and I didn't expect it to be in your Li Zheng's hands."

The original work of Luban Lock was only known when the ancient tomb was excavated in later generations.

There have always been Luban Locks in history, but I don’t know which one is the real one.

It was not until later archaeologists dug up a tomb in the Han Dynasty that they knew the true appearance and origin of the Luban Lock.

Li Zheng said: "Actually, I still have a lot of skills in my hands. I wonder if Yan Dajiang is interested in learning about it."

"I still want to know what the water pressure you are talking about?"

"In addition to water pressure, there is also air pressure." Li Zheng said to Yan Liben again: "I wonder if Yan Dajiang is interested in staying in Jingyang and helping me create things? I have more technology in my hands."

"This..." Yan Liben was a little embarrassed.
