The research group does not deal with the physical problem.

However, it is quite similar to the Hanlin Academy in later generations, which only involves theoretical research.

Of course, their research would be printed in a book and then released.

What they do now is very simple, which is to verify the content in the textbook, which helps them to start to really grasp the content in the textbook and finally use it for themselves.

For some people, they are not good at dealing with people, and they are only willing to do what they like behind closed doors, and the treatment of the scientific research group is quite good, for them, it is enough to live in peace.

At this time, Chen Zhengye had already begun to recruit craftsmen.

Erpigou here, there has been a lot of experience in large projects, but this time the project is more vast, it needs to coordinate all walks of life, and it requires a lot of labor, and the labor is not clear about the type of work.

If it was in the early years, the only thing that could have such organizational ability in this world was the Ministry of Industry of the imperial court.

But even for the Ministry of Industry, it takes countless hours to prepare for such a thing.

And now, here in Erpigou, people like Chen Zhengye may not have a clue when they do these things! After all, there is experience, there is a backbone, and they know what kind of people to look for, how to allocate human resources, how to contact various workshops, and prepare for the start of construction.

But even so, Chen Zhengye still felt that this matter made his hair gray, he hadn't closed his eyes for many days, even in his dreams, he was thinking about countless chores.

There were many people who came to apply, and with the labor recruited from all over the Chen family, there were soon thousands of people on a considerable scale.

Of course, these thousands of people are just engineering personnel, and the other manpower involved in workshops such as sleepers, wooden rails, and steel is innumerable.

In the workshop, many kinds of sleepers and wooden rail styles have been designed, and they have been tested many times before, so the standard of the rails has been completely set, and then the order is placed and ready to start.

Of course, before the start of work, according to Chen Zhengtai's instructions, these laborers will be gathered by their respective foremen for a short exercise.

Besides...... A new thing was applied, the gunpowder in the gunpowder workshop.

The structure of the fire gun is very simple, but when Chen Zhengtai sent this thing to Li Shimin, Li Shimin scoffed at it.

Because this thing...... The firing range is not high, which is not very useful in Li Shimin's view, it is more like chicken ribs.

What's more, the cost of this thing is higher than that of bows and arrows, and Datang's iron cavalry already has a suppressive power against the enemies of the desert, so why do you need this thing, can this thing be used immediately?

Chen Zhengtai was full of enthusiasm, and as a result, he was directly poured a basin of cold water by Li Shimin.

Since you don't want it in the army, then ...... Chen Zhengtai simply used it for these laborers.

After a simple military drill, they were taught how to load the medicine and how to keep the queue.

After all, a lot of materials still need to be prepared, and someone needs to do the surveying, so the laborers have a month to do nothing.

At present, they are not paid, but they are provided with three meals a day, and the only thing they do is to conduct queue drills.

Everyone lined up from morning to night, naturally...... This caused a lot of complaints in the hearts of many laborers.

They had come to work and to provide for their families, but who would have expected them to become soldiers.

In Datang, people don't discriminate against martial artists, of course...... A real martial artist, on the contrary, is admirable.

It's just that there is a discriminatory atmosphere of auxiliaries, the so-called auxiliaries, in fact, are just miscellaneous servants, once the battle, they are recruited, the warriors ride horses, they follow behind to feed the horses, the warriors charge, they carry knives in the back swarm to follow.

It is almost difficult for such a person to obtain military merits on the battlefield, and after the end of the war, he is almost disbanded and returns home to farm.

For these laborers, they feel that what they are doing now is an auxiliary, so they complain.

Fortunately, the Chen family has enough prestige in Erpigou, so as not to cause a mutiny, not to mention three meals a day, the food is not bad, so even if the drill is harsh, it is only limited to a controllable range.

Chen Zhengye is obedient to any explanation of Chen Zhengtai, after all, the memory of digging coal is too terrifying, don't look at the young age of the head of the family, he looks like a talent, he can do anything.

Therefore, Chen Zhengye is very cautious, Chen Zhengtai explained five points, and he had to do nine points to rest assured.

The wives and concubines in the family complained at first, but they soon stopped, after all, they were not willing to let their men be subjected to family law.

On the one hand, it is the psychological shadow caused by digging coal, for fear of being sent to the coal yard again, on the other hand, it is also the experience in the coal yard, to a certain extent, it also makes them learn to be patient.

In the grassland, thousands of miles away, the number of people leaving the customs has increased day by day, and the pastures have expanded from three or four to fourteen. The cultivated farmland has also begun to grow gradually.

A large number of laborers began to look for opportunities in Shuofang.

The walls of Shuofang have begun to take some rudimentary shape, and some merchants have followed, for the merchants, the best business is to do here, most of the people in the Guannai are still self-sufficient, and those ordinary farmers may buy things all year round, but some needlework and thread.

But outside this pass, laborers and craftsmen have salaries, but there is no way to be self-sufficient, all the necessities of life, can only be purchased, to exchange, can be obtained, so although there are only tens of thousands of people here, but the consumption power is huge, even the ordinary hundreds of thousands of cities, if you do not add those poor and luxurious dignitaries, the consumption power may be far less than here.

With the arrival of many merchants, many fine tea shops and inns appeared in the city.

After all, the merchants have money and are willing to use the money to enjoy a luxurious life, so here, it also attracts a lot of orchids, who play the pipa and sing pleasant songs.

The river leading to the city, slowly descending, floating on a lot of boats, boats piled up a large number of goods, at this time the grassland, there is no wind and sand, although it is cold, but only at night, do not look at some details in the city, but can also see a little fireworks in March Yangzhou scene.

The only thing that worries people is that in the Turkic camp outside the city, there are more and more disputes between the Turks and the Han Chinese.

In his heart, the Han people were just building a military fortress, which did not matter to him, but once the Han people went out of the customs, they would definitely bring more mutual market demand, and there was a lack of many materials on the steppe, so that the Turks could use this to exchange their own leather goods and cattle and horses with the Han people in exchange for a large amount of tea and salt, and even luxury goods.

But gradually, he began to reminisce.

Dare to love his brother, he didn't plan to come to the mutual market at all, the Han people actually came here to farm, and even opened a ranch here, they ...... I want them all.

This kind of vigilance gradually began to spread, but the Tuli Khan did not dare to be disrespectful to the Tang Dynasty, and he did not want to be attacked by the Tang army.

But...... This does not mean that he has no heart and eyes and is at the mercy of others!

The request attached to the original request was just to get the support of Datang and let him gain a foothold on the grassland, but once he ...... The steppe can't get a foothold, so ...... Where will the Turks go? As the leader, did he really become a Tang Chen?

So he simply began to indulge the conflict between his people and the Han Chinese, and no longer had the same strict restraints as before.

Many Turkic people and Han herdsmen clash more and more with each other, and even large-scale raids.

And the Chen family in Shuofang City began to negotiate with the Tuli Khan, and the Tuli Khan only made a haha and verbally apologized, saying that he would definitely track down the perpetrators, but ...... It's more about words, it's still what it should be!

Thus...... The negotiations had no effect, and the Han herdsmen began to fight back, but the Turks, who had originally come to protect Shuofang, now began to become an obstacle for the Han people, and more and more reports appeared on the desk of He Li, the governor of Shuofang.

He Li was extremely grateful to Chen Zhengtai, he never imagined that Chen Zhengtai would value himself so much, he was just a lost dog, so he was relieved to let himself come to Shuofang to lead the troops, and after that, he made himself the chief manager of Shuofang, in charge of the safety of the entire Shuofang City.

This made Qi Bi He Li feel like he was dying for his confidant, and he was determined to give his life to the Chen family for the rest of his life.

Looking at the telegrams, he was annoyed, but at this time, he was no longer the leader of the Tiele tribe, since the defeat, he has become much more cautious than before, although there are often times when blood surges, but he knows that the Turks at this time are still allies of the Chen family, although this alliance is not stable, but once the conflict is intensified, it will inevitably cause Shuo Fang to be in danger.

Not to mention the direct hostility of the Turks, once the Turks no longer protect Shuofang City, it will also cause a lot of trouble!

Now this recipe ...... After all, it has not really begun to gain a firm foothold in the desert, which has a huge potential danger for Chen's business in the desert.

Therefore, he chose to endure it temporarily, on the one hand, he continued to negotiate with the Tuli Khan, and even went to the Tuli Khan's tent several times to drink, but soon, he realized ...... The problem was worse than he had previously thought.

At a recent banquet, the drunken Tuli Khan began to tell him about the origin of the Tiele tribe, and then asked him, how can you submit to the Han Chinese if you are a descendant of the Khan of the Tiele tribe?

Qi Mi He Li just laughed to cover up the past, he originally wanted to accuse the Tuli Khan, you Tuli Khan, aren't you also attached to the Han people? It's just that you have sworn allegiance to Emperor Tang, and now you are saying such a betrayal of the alliance, calling it a slave with three surnames, which is not an exaggeration.

Qi He Li has now learned to be a little flexible, although he has something in his heart, but he still chooses to be silent!

After drinking, when he returned to Shuofang City, he immediately began to order the fortifications of the city, and began to organize the craftsmen and laborers in the city to take turns to practice.

Then, he immediately repaired a letter and asked people to send it to the customs quickly.

Chen Zhengtai, who was on the other end, looked at the letter after receiving it, his face was indifferent, and he didn't seem surprised.

For him, there is no need to question the loyalty of Qi He Li, the reason why he dares to entrust this person with a heavy responsibility is that he knows that this Qi He Li is a loyal person, since he surrendered to Datang, he has no rebellion, and even has a deep affection for Datang.

As for the Turks, it is completely different, although the Turki Khan is a brother and brother with him, but there is a bit of sincerity here, they all know it in their hearts, not to mention that the reason why the Turki Khan chose to attach to the Tang Dynasty was actually just an expedient measure, and he was unwilling after all.

Originally, if the Tang Dynasty did not go deep into the desert, but only adopted a restrained strategy, perhaps the Tuli Khan would still be willing to endure it all the time.

And once Datang wants to directly intervene in the entire desert, it will inevitably trigger a strong backlash from Tuli Khan.

The question now is no longer whether the Turks will betray the alliance, but when.

Chen Zhengtai understood this very well, and this matter was not only the Chen family's business, so he immediately brought the matter to the court.

So soon, Li Shimin summoned Chen Zhengtai to the imperial front.

Chen Zhengtai had already prepared and soon entered the palace. It's just that Weng and his son-in-law met today, and they were a little embarrassed.

Of course, there are some things, although everyone knows it in their hearts, but it's better not to pick it up, so Li Shimin pretended to be stupid, and Chen Zhengtai also pretended that nothing had happened.

Li Shimin didn't talk nonsense, and went straight to the point: "Has the Turkic people's intentions reached such a point? ”

"Yes." Chen Zhengtai said very seriously: "The minister thinks that with the increasing expansion of Shuofang, Tuli will inevitably be unable to continue to endure it, and the war may be provoked at any time." ”

Li Shimin frowned, his hand was gently patting the case, his beat was very rhythmic, usually at this time, it was time for him to start thinking.

After a long time, Li Shimin looked at Chen Zhengtai and said, "What do you think?" ”

"Do your best to be prepared." Chen Zhengtai continued: "The best way is to strike first, simply take advantage of their unpreparedness and directly take down the Turki Khan. ”

When Li Shimin heard this, he shook his head and smiled: "You are resolute and resolute, and you have a very good demeanor." ”

Chen Zhengtai immediately said modestly: "People say that a son-in-law is like a father-in-law." ”

"Is there such a thing?" Li Shimin was stunned for a moment, racking his brains to find this allusion from his poor knowledge.
