Henan is eroded for thousands of miles, and the emperor is furious.

It was confirmed that there were no large bandits near Zhangde Mansion and Weihui Mansion, and there were no major projects, and the "Red Flag Army" was named by the emperor to march west and go south to participate in the suppression of the Kou.

As early as September, the merchant ships that took the displaced people to Ningyuan and Lushunkou sent the winter clothes of the soldiers, and also sent 500 four-wheeled carriages produced by Tiger's Den City.

After Huang Yi saw his brother, he was happy to give a detailed review of what he had learned in the past six months, his face was full of pride, and he even wanted to follow his second brother Huang Yong to the sea to find Xiyi's bad luck.

Due to the continuous expansion of the production scale of the weaving mill that was put into production last year, the output has doubled several times.

The marching tent sewn by the clothing factory using oiled canvas can fully meet the needs of 20,000 troops, and the canvas tent replaces the cowhide tent to save too much cost, which makes the price of cowhide fall, and the cost of cowhide combat boots also decreases accordingly.

The use of oiled canvas and the production of backpacks based on Huang Han's design drawings have become the standard for every regular soldier.

Such a backpack is beautiful and has a large capacity and is waterproof, not only for military use, but also sold in the private sector, but the zipper is a thing Huang Han forgot to open the gold finger, and the backpack still takes buttons and drawstrings to tighten the pockets.

In this era, most people go out to travel is to pack a bag, or to use wooden, rattan boxes, inconvenient and not strong, with the new product of backpack, I believe it will not be long before it will become a must-have for travel and business.

Tung oil waterproof is not Huang Han's golden finger, the umbrella of this era is the use of kraft paper and thick cloth after the drying of tung oil, many oil paper umbrellas in the romantic Jiangnan also depict mountains and rivers to become a scene in the rain.

The advent of tung oil-coated canvas has upgraded the soft sails of warships and merchant ships in the "Red Banner Army" system, increased the waterproofness and anti-corrosion of the sails, and naturally doubled the service life of the sails, which will save too much cost, and the oiled canvas will become a fist product sold to Europe in the future.

Daming's textiles originally have the world's leading technology, with unparalleled competitiveness, similar to the kind of multi-rotor spinning technology of Jenny spinning machine, Jiangnan folk have long had.

Many skilled craftsmen cooperated with the young people of the Xinxue Research Office, and they collected the brainstorming ideas of various multi-rotor spinning machines, and finalized the Huang's spinning machine with four turns, eight turns or even as many as 16 turns.

Nowadays, it is common for women in Tiger's Den to spin wool, cotton, and linen threads on spinning machines with eight spindles, all of which are the products of the equipment manufacturing branch of the iron and steel mill.

Under the leadership of the instructors and students of the Xinxue Science and Technology Class, the craftsmen in the system and several masters of the Sun Yuanhua family devoted themselves to research, and they often disassembled the looms brought by the Sun family and reassembled them.

Not long after, the Huang's loom, which replaced many wearing parts with steel and spring steel, was successfully developed, and the advanced loom with steel and copper as the main components was mass-produced through actual operation.

Now the weaving factory in Tiger Den City adopts modern management to produce canvas width that is larger than that of Xiyi products, the density has been strengthened, and the quality has been raised to a higher level.

Then the use of the Han people's traditional tung oil anti-corrosion, waterproof technology, more leading the world, to the international market after the best-selling Europe.

The Ming Dynasty was actually a very open era, and there were countless scholars and doctors engaged in scientific and technological research, such as Xu Guangqi, Zhang Xie, Bi Maokang, Zhao Shizhen, Song Yingxing, Fang Yizhi, etc., all of whom left research results.

Many Ming scientists did not rest on their laurels, as evidenced by the fact that high-ranking officials such as Xu Guangqi and Wang Zheng devoted themselves to the study of Western studies, and if it had not been colonized by the evil Manchu Qing for nearly 300 years, the Han Chinese would not have become the sick men of East Asia.

In order to allow Wang Zheng, who returned to his hometown to live idlely after being amnestied, to exert his residual heat, but also worried that he would be harmed by the exiles, at the end of last year, the dart master of the "Quartet Express" went to Wang Zheng's hometown in Jingyang County, Xi'an Prefecture, and asked him to go to Tiger's Den City to teach a new school.

It was impossible for him to refuse, because Huang Han knew about this historical celebrity and his book "The Diagram of Strange Artifacts in the Far West", and the flag guard who went to invite him only said a word, and the scientist agreed without hesitation.

Wang Zheng was not only a talented scholar, but also a devout Catholic, and when the Qiwei told him that he could preach freely in Tiger's Den City, it was a matter of course.

Xu Guangqi had many long conversations with Huang Han, revealing that he was tired of the deceit in the court, and he wanted to retreat to Tiger's Den City to teach Xinxue and teach those children geometry and mathematics.

Of course, Huang Han didn't want Master Xu to die in office like history, so he taught Tai Chi, arranged for Wu Youxing and Li Zhongzi's old apprentices to visit the door regularly to check his body, and tried his best to rescue Sun Yuanhua so that the old man would not be sad, etc., all so that Xu Guangqi could live a few more years.

Now the situation is good, Xu Guangqi is strong-boned, he is ready to go to Tiger's Den City to teach at the end of this year, "South Xu and North Wang", the two powerful scientists who study Western studies, will all become talents in the "Red Flag Army" system in the future.

With their participation in the education cause in the system, it will be much easier to poach Zhang Xie, Bi Maokang, Song Yingxing, etc. to teach and conduct scientific research in Xinxue.

After receiving the holy decree, Huang Han immediately led his men and horses to the west without hesitation, because the pursuit was fast and the fight was fierce, which meant that the seized grain, gold and silver treasures would not be less.

1,000 four-wheeled wagons carried wheat, vermicelli, vermicelli, black beans and other grains, and 2,000 wheelbarrows carried 7,000 stone of grain.

After the outstanding guards were turned into regular soldiers again, the number of regular soldiers had already reached 7,000, and the shortage of the guards army would naturally be filled by activists from among the military service, and the number of regular soldiers would remain at 5,000.

At the time of departure, a full 8,000 miscellaneous servants were selected to accompany the army, and most of the miscellaneous servants had the task of serving war horses, driving carriages, and pushing wheelbarrows.

The cavalry commander who remained in Houjiazhuang was Ma Fulin, who had just been promoted to the rank of actual commander and always possessed guerrilla warfare, and more than 100 of the 360 cavalry he owned were veterans brought from outside the Guan, and the rest were guards who had just been regularized.

He Shouxin, the small flag officer of the propaganda team, was promoted to the chief flag officer to stay behind, and he had under him Luo Mingshi and other small flag officers and dozens of propaganda team members whose hometown was not far from Houjiazhuang, who not only had to publicize and agitate, but also assisted in the management of civil affairs.

Gu Rushan was promoted to become the acting general because of the very disciplined management of Sun Liuzhuang, and there were also 360 regular sword and shield men, spearmen, foot archers and gunners under his command, most of whom were also guarded troops who had just turned into regular soldiers, and he also had 1,000 Xiangyong armed men who began to complete regular training.

In the event of an emergency, Ma Fulin, Gu Rushan, and He Shouxin could call on 5,000 young men who practiced with ash pole spears every three days to participate in the defense of the base area.
