When Li Shimin had not yet ascended the throne, when he was still the king of Qin, the eighteen scholars of the Qin Palace's mansion were all Li Shimin's henchmen, but since he ascended the throne, many people have been dormant.

They don't show their heads in the court, even if they are all dormant, except for the military generals, the Manchu Dynasty Wenchen They are still the people Li Shimin relies on the most.

Some are gone, some are gone.

At that time, Fang Xuanling, the eighteenth bachelor of the Qin Palace, and some of Du Ruhui were still in the court.

Among the eighteen bachelors of the Qin Palace, Yu Shinan, who just died last year, is one of them.

Li Shimin took out a copy of Yu Shinan's recital, "This is what Yu Shinan gave to me before leaving." ”

Zhang Gongjin took the chapter and looked at it carefully and said: "Your Majesty, Yu Shinan has specialized in calligraphy all his life, and he is more accurate than reading people. ”

Li Shimin bowed his head and said, "Then do you think what Yu Shinan said is right?" ”

"Yu Shinan said that Li Zheng is very arrogant in his heart, and this kid still needs to be tempered well to recover." Zhang Gongjin thought for a while and then said: "From the courtier's point of view, Li Zheng is not a good child, he doesn't want power or fame and fortune, but all he wants is money." ”

Li Shimin drank tea and said, "You go on." ”

"Whoa." Zhang Gongjin continued: "The contradiction between His Majesty and Li Zheng is here, there are many strange people in this world, and many strange people have a strange temperament, and people who have always loved money can't do anything big. ”

Seeing that Li Shimin was about to speak, Zhang Gongjin continued: "Your Majesty, and listen to the minister, if Li Zheng makes the whole 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 compromise means for money, then Li Zheng is just a fat sheep to be slaughtered." ”

"Fat sheep?"

Zhang Gongjin nodded, "Yes." ”

Li Shimin smiled, "What you say is really ......"

Zhang Gongjin arched his hand and said: "Although I don't like it, it is true, as for whether Li Zheng will become His Majesty's fat sheep, it depends on his own creation." ”

The two of them smiled.

Li Shimin poured a cup of tea for Zhang Gongjin with his own hands, "You and I haven't talked like this for a long time, I still need you to recuperate." ”

"Your Majesty is worried." Zhang Gongjin said in a low voice.

Li Shimin watched him drink the warm tea, and said: "Chaoji envoy Wushi Tong will go to Chang'an tomorrow, and when he returns to Chang'an, how do you think he should be settled." ”

Every year at the Yuan Meeting, the envoys from each state have to return to Chang'an to report on the situation of inspecting the states, which is the work of the envoys of the court.

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

"I don't think it's too high, and it's not too low." Zhang Gongjin coughed after speaking.

Li Shimin patted him on the back and helped him smooth his breathing.

"The minister is rude." Zhang Gongjin bowed.

Li Shimin looked at his face and said with a sad expression: "Go back early to rest and recuperate." ”

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 were still a few of the eighteen bachelors of the Qin Wangfu back then

Yan Liben didn't sleep for a day and a night, but he still left the Ministry of Industry and went to Jingyang.

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

"Did he unlock Luban?"

"Nope."

"Nope." Li Zheng said decisively.

In two sentences, Yan Liben was rejected.

Yan Liben stood at the entrance of Jingyang Village with a worried expression, "How is it?" Has the county Hou Ken seen the old man? ”

Li Yifu came back and sighed and said, "The county marquis said no." ”

Yan Liben gritted his teeth and stomped his feet and said, "If Li Zheng doesn't see the old man, the old man won't leave." ”

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

Until late at night, Da Niu helped Li Zheng unload the last vat of petals from the still.

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

"Which guy?"

"It's the person who gave the Rubik's Cube before is called Yan Liben."

"He's still outside?"

"Yes." The bull nodded.

Li Zheng patted his head, the ancients were really stubborn.

"Big Niu, bring people here."

"Okay."

The big cow carried the lantern and went to the entrance of the village.

Seeing Yan Liben's arrival, this guy looked decadent, and the dark circles under his eyes were very heavy.

Li Zheng looked at his expression and said, "Master Yan, why are you so troubled. ”

Yan Liben took out the Luban lock and said, "How do you solve it?" ”

In my mind, I walked through the various planes of the Luban lock, and after noting down the order, it was actually easy to unlock.

Li Zheng said to Da Niu: "Da Niu, you come." ”

"Okay."

Da Niu took the Luban lock.

"Will you solve it?" Yan Liben looked at Da Niu's gaze a little incredulous, this was a child who was only ten years old.

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? The old man had never heard of this skill. ”

"It's actually a math problem, too."

"Mathematics, is it mathematics?" Yan Liben was gnawing on the sweet potato, his eyes kept staring at the movements of the big cow, this child had already disassembled four pieces of wood.

Waiting for the big bull to draw out the sixth article, Yan Liben roughly saw some clues.

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

When the big cow pulled out a wooden bar on the top, the entire Luban lock disintegrated and scattered on the table.

"That's it?" Yan Liben swallowed a mouthful of sweet potatoes hard.

Da Niu grinned: "Actually, this is what we put on." ”

After speaking, Da Niu took out a bunch of drawings again, "This is the homework that the teacher gave us." ”

Yan Liben looked at the drawings and glanced at Li Zheng again, speechless for a long time.

"You go back to sleep first." Li Zheng said to Da Niu.

Da Niu stood up and said, "That student sleeps with Brother Da Hu tonight." ”

Dahu is a little older, but the two children get along quite well.

Li Zheng said to Yan Liben: "With this drawing, presumably Master Yan can reassemble the Luban lock." ”

"With the drawings, of course, it is not a problem." Yan Liben said excitedly: "This is a long-lost craft, I didn't expect it to be in your hands Li Zheng." ”

The authenticity of the Luban lock was also known when the ancient tombs were excavated in later generations.

In history, the figure of Luban lock has always been there, but which one is genuine has never been known.

It was not until later archaeologists excavated a mausoleum in the Han Dynasty that they knew the true appearance and origin of Luban Suo.

Li Zheng said: "Actually, I still have a lot of technology in my hands, I don't know if Master Yan is interested in learning about it." ”

"The old man still wants 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 Master Yan is interested in staying in Jingyang and helping me make things?" I have more technology in my hands. ”

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

"It's okay, you can also take the affairs of the DPRK and China with you."
