"Zhang Gongjin expanded the scope of the Imperial Protectorate, supervised the original Eastern and Western Turkic lands, Jiangnan, Lingnan, increased the number of sailors by 10,000 and sailors by 20,000, and increased the penetration of Tianzhu." Li Shimin continued.

A meeting, three consecutive days, before the Zhenguan seven-year plan was set, the only thing that felt insufficient was the population, but the New Year's transfer was still dominated by the older generation of alien races, so that they could go to fight for the Tang Dynasty and win credit, which was also a kind of restriction, so as not to stay in the Central Plains, and also to supervise the troops, which was a waste of manpower.

After discussion, almost all the warriors of the Turkic, Hui and other major tribes were mobilized to fight, and under the rich reward, even if someone sacrificed, they all thought it was worth it, and they supported Li Shimin even more.

Zhenguan added 600,000 new babies in the sixth year, and according to statistics, there were 600,000 Han people, plus the increase in the population of one million in the rest of the departments, which made Li Shimin very happy, which means that after 18 years, the worst is hundreds of thousands more young people.

"Without Feng Weiguo this New Year, it is always not so lively, and even the opera house in the city is almost full of old programs, which is really boring." Li Yuan, who is more and more energetic, complained to Li Shimin and his wife who came to the reunion year.

"The country is in the Western Regions, and I will attack Khotan after the year, and then I will mine Kunlun white jade for your father." Li Shimin and his wife glanced at each other, and the helpless Li Shimin opened his mouth to explain.

Feng Daiwen's ability to innovate is not something that everyone can do, after Li Yuan said this, several people thought about it carefully, and it was really true, when Feng Daiwen was in Chang'an, he would do some things somewhat, and it was always so unique and useful.

Occasionally, something can bring great benefits, even if you don't toss anything, and the ideas are very inspiring.

"Hehe, hehe, yes, yes, what a good boy." When Li Yuan heard this, his eyes rolled slightly, and he praised again and again.

"Father, you promised not to leave Chang'an." It is said that knowing the son is better than the father, and vice versa, Li Shimin saw Li Yuan's appearance, and hurriedly persuaded him.

"Humph! I know that my words count. Li Yuan snorted and chirped dissatisfiedly.

………………

Just when Chang'an City was bustling with New Year's Day, Feng Daiwen also came to have guests.

"Ice and snow, why did you come to the Western Regions?" Feng Daiwen pulled Liu Renshi to the edge of the stove and handed over a cup of hot tea, and asked curiously.

"Thank you, Brother Feng, I automatically asked Ying to come to deliver the letter, firstly, I wanted to make some credit under the Governor, and secondly, I wanted to bring my father and Zhang Liang to apologize." Liu Renshi poured a big gulp of hot tea and let out a long breath, then said with an embarrassed smile.

"Apologize? What's going on? What is there to apologize for? Just say no in the future. Feng Daiwen asked curiously.

"Originally, the father and the family said that they wanted to subscribe to a boat, and they knew that the cost was so huge, and a ship would cost 2 million yuan, and the family really couldn't take it out, so they had to pull a few more people into the shares.

Father, they really don't have the shame to come to see you, no, I'm the only one who runs. Liu Renshi said helplessly.

At this time, people pay attention to being like a daughter, and Rao is Liu Hongji's rogue background, so he is not embarrassed to come to face it.

"Hehe, it's such a trivial matter, why bother, I'm saying that this is also my thoughtlessness, how can I blame them." Feng Daiwen laughed, waved his hand disapprovingly, and said.

"This is not true, if you don't come in person, I feel uneasy, and the saint asked the military department to set a list, and next year to start fighting the small countries in the Western Regions, my subordinates got the news, so I asked for a favor and reported it first." Liu Renshi said with a smile.

"Since you are here, you have a good rest, how do you have to march after spring ploughing, the people of the Western Regions do not understand production, and they plant indiscriminately, we can't be the same as them, and when the army arrives, we will take it in one fell swoop with the momentum of thunder." Feng Daiwen explained with a smile.

"Good, the last will be at your command." Liu Renshi replied respectfully.

"During this time, you will accompany King Wu and them first to adapt to the climate of the Northland." Feng Daiwen was too lazy to get the wind and dust, so he directly started to pick people up.

…………

In the middle of February of the seventh year of Zhenguan, Feng Daiwen ushered in a group of unexpected people, Duan Zhixuan took Feng Daihuo, Xi Junmai, and a thousand Xuanjia troops to escort Li Chunfeng and other 200 people from the scientific research institute to Gaochang.

As soon as Feng Daiwen saw Duan Zhixuan, he understood what Li Shimin meant, this is to allow himself to use gunpowder, and he secretly wrote a book before, saying that gunpowder is a sharp weapon for opening mountains and splitting stones, and it is better to use it to open mountains and find deficiencies in its use.

And Li Chunfeng and others were also asked by Feng Daiwen to come, intending to make steam armored vehicles to break the city.

Feng Daiwen found a small courtyard alone, and more than a dozen craftsmen who were closely protected lived in it, and a thousand Xuanjia soldiers took turns guarding it.

Feng Daiwen, who had been prepared for a long time, asked people to transport the materials in, and specially prepared several more ores, so that people could not guess the specific formula.

Li Chunfeng and others are very proficient, but this time the requirements are more special, only the driver and the person who adds coal, in front of which is an iron rod that is small in front and large in the back, one zhang and five feet long, specially designed to deal with the city gate and earthen wall.

Use the power of the machine to break the city, and the all-steel body can make the enemy helpless.

These little things were handed over to the craftsmen, and Feng Daiwen took Li Chunfeng and Duan Zhixuan to hide in a small steelmaking workshop.

Fill steel molds to make thick cannon barrels, and use gunpowder to make solid cannons.

Solid cannons are not good against skirmishers, but they are much more powerful than catapults when used to hit city walls.

There is no high explosives, cotton thread is made of cotton, long steel pipes are made into arquebuses, filled with more than 100 small iron beads, the lethality is huge within 50 meters, and the attack area is large, and the leather armor can be penetrated at a distance of 10 or 20 meters, which is used to fight street battles, and it is very good to fight at close range.

The disadvantages are also obvious, it cannot be used in rainy days, the effect on iron armor is extremely poor, the attack range is short, and the reload is slow.

However, these can be slowly improved, Li Chunfeng proposed, using thick paper soaked in oil, not only can be waterproof, but also directly wrap gunpowder inside, each package is packed, not only the dosage is accurate, but also convenient.

When you use it, you can tear it up and pour it in, then fill it with iron sand, and tighten it with an iron rod to launch it again.

This can be used as a mountain forest, a city for close combat.

According to this characteristic, the flowering bomb was also made, and the warhead was made of copper that was easy to shape and molded, and after the warhead reached a certain distance, a secondary explosion was formed, and a large number of iron balls in the warhead would hit the enemy group at close range.

Specially mobilized 300 Xuanjia troops to be gunners, and let 500 Xuanjia troops be gunners, and arranged 1,000 Guanzhong Liangjiazi as professional logistics to keep the projectiles.

Due to the disadvantages of gunpowder, it was necessary to have trained professionals to carry it.
