"This ......"

Li Yan's words made the faces of the three officials from the Ministry of Industry look quite ugly.

It is true that they also know that what they have created is not too good, but it is very painful for Li Yan to dry them after receiving three folk craftsmen.

"With such an intricate structure, it only took six days to build this object, and my results are definitely the best in the world!"

The three officials argued stiffly, but unfortunately they were slapped in the face just three minutes later.

The people who came were three folk craftsmen, and the crankshaft connecting rod device they brought was much smoother than the previous one in the process of sliding.

After careful observation, Li Yan found that the reason why the finished products made by these three people were so silky was entirely due to the ancestral polishing process.

They had already polished the parts carefully before putting them together, so they reached a level that surpassed the three members of the Ministry of Engineering.

"Yes, the three of you can enter the Heavenly Crafting Academy."

Li Yan's decisive decision made the faces of the three officials and craftsmen of the Ministry of Industry turn green.

It's a pity that Li Yan has a knighthood and a much higher status than them, so they had to bear the strange eyes of many craftsmen and obediently slip back.

They decided to go back and disassemble the imitation and re-polish it, believing that if they were not lazy and polished it perfectly, the quality would definitely be higher than that of the finished product of this folk craftsman!

……

From this day on, many craftsmen came to deliver the work one after another.

A significant number of people have already completed the imitation of these two things, but the quality is higher or lower.

Li Yan selected twenty of the most capable people to become the first batch of members of the Datang Tiangong Academy.

After that, Li Yan organized the remaining craftsmen to conduct a wave of Q&A.

This Q&A session is that Li Yan wants to choose people with a certain degree of creativity and cultivate them as seeds for the next stage of development of Tiangong Academy.

In the end, after the seventh day, all thirty people were elected, and the Datang Tiangong Institute was announced to be completed.

Li Yan specially spent a sum of copper money to purchase a spacious courtyard in the city as the place where the Datang Tiangong Institute was settled.

Of course, the location of this courtyard is not prosperous, if it is described in modern terms, it is a proper area outside the seventh ring road of Chang'an.

In this way, the five-character plaque of "Datang Tiangong Institute" reproduced from Li Shimin's own handwriting was hung, and the Datang Tiangong Institute officially started.

Li Yan's first project goal is the research and development of hand-cranked looms and their related derivatives.

The task of the first stage of the first industrial revolution of Datang is naturally to improve productivity so that Datang can gain a stronger receptivity, so as not to suddenly get out of control in the continuous changes from outside.

At this point, Li Yan seems to have been deposited again, and for two months, Li Yan's name rarely caused widespread discussion in Chang'an City.

It's just that the popularity of Li Yan's two words has subsided in the past two months.

These two months are the spring of Datang, which happens to be the right time for potato growth.

So by the time we enter May, the potatoes are ripe.

A news that "Dingbei Hou brought thousands of catties of crops per mu to Datang" swept the entire Datang in a short period of time!

In some areas, some people even call potatoes "Li Hou potatoes" to show respect for Li Yan.

After the potatoes were ripe, Li Shimin also reacted quickly.

The grain borrowed from the previous monument was returned as soon as possible, and even in order to show the generosity of the imperial court, Li Shimin also returned an extra percent to the people.

It's a pity that most of the people who choose to donate grain in exchange for being famous for future generations, and there are still a few people who choose to borrow grain from the imperial court.

So, when Li Shimin counted the reserves of potatoes after harvesting, he resolutely decided to return eighty percent of the grain donated at the beginning! And the stone tablet of the donated grain will still be kept forever, so that the name of the donor will be passed on to future generations.

Thanks to this commotion, Li Shimin's reputation among the people suddenly rose a lot.

It's almost a fight with Li Yanyou, the discoverer of potatoes!

The people are grateful to Li Shimin, and selectively ignore the bad record of this person when he took the throne two years ago.

After harvesting this prestige, Li Shimin naturally had to consider how to reward Li Yan.

"Seal a county duke? No way! If it is sealed like this, how can it be sealed in the future if this kid goes out to fight and make meritorious contributions! ”

"Do you want to give a marriage? Well, yes, let me think about it......"

Li Yan laughed heartily in the imperial study.

Now that the yield of potatoes per mu has been confirmed, Li Shimin seems to have seen the prosperous situation in the future.

The most important thing is that the person who created this prosperous world is none other than Li Shimin!

"I don't know what happened to this kid and the Tang Tiangong Academy, my secret agent in the DPRK and China can't find out any news......"

Li Shimin suddenly sounded the Datang Tiangong Institute mentioned by Li Yan before.

According to Li Yan, this potato can bring sufficient food reserves to Datang, and what Tiangong Institute brings to Datang is the improvement of productivity in all walks of life!

Although Li Shimin didn't quite understand what productivity meant, he still felt it made sense.

So, Li Shimin immediately made a decision.

"Wang De, inform me that I will go to Dingbei Hou's Tiangong Academy this afternoon to inspect it, so that Dingbei Hou can get ready!"

Li Shimin decided to take a trip in person to take a good look at the true appearance of the Datang Tiangong Institute.

"Yes, Your Majesty."

Wang De hurriedly responded, and then immediately sent someone to arrange Li Shimin's travel.

……

In a single-family courtyard of the Tiangongyuan, craftsmen who are good at making woodware have basically mastered the production of Jenny machines, and are studying the production of water-powered looms.

On the other side of the Tiangong Academy, the ten craftsmen who were finally selected by Li Yan were receiving Li Yan's guidance.

What Li Yan is teaching them now is design and drawing, and drawing is the top priority, and Li Yan still attaches great importance to this part.

"Okay, that's almost the end of the talk, let's rest if you should rest."

After an hour of hard work, Li Yan ended today's explanation.

"Hou Ye is really the culmination of the world's mechanical skills, if it weren't for Hou Ye, I would never have been able to touch such exquisite skills in my life."

"Yes, I never thought that we craftsmen would have to master the art of cartography, let alone that cartography would be so possessed!"

"It's worthy of the Hou Ye!"

These ten craftsmen with active brains and a certain amount of creativity in thinking have considerable emotional intelligence.

At least in terms of sycophancy, Li Yan even felt that they had a fight with Zhang Dazhu.

"Master Hou, a father-in-law came from outside the Tiangong Academy, and he said that His Majesty would come to the Tiangong Academy this afternoon."

Suddenly, the nurse who was in charge of guarding the Tiangong Courtyard came in to report.

As soon as the nurse finished speaking, the room was boiling.

"Your Majesty is coming? Shall we see the Blessed Face? Ancestors bless! ”

"Your Majesty will come here, we are really stained with the light of the Hou Ye!"

"That's it, it all depends on the face of the Hou Ye."

It didn't take long for the boiling to become a group of craftsmen with high IQ and EQ who were not low in IQ and EQ and began to instinctively pat on the back, quite skillfully.
