Wuzi steel ingot is better than blast furnace fired steel, but the hardness is obviously worse than the alloy of later generations, the toughness is good, Feng Daiwen decided to improve it, add a common ore, manganese ore to synthesize manganese steel, improve the hardness, it just so happened that Feng Daiwen knew that there was manganese ore, after smelting Wuzi steel into manganese steel, after repeatedly forging, quenching with frozen mountain spring water, three days and three nights, Feng Daiwen took two skilled craftsmen to forge a knife as thin as silkworm wings, which can bend the tip of the knife to the handle of the knife and loosen it to recover quickly, and the experiment found that it was extremely sharp, a knife can easily cut off the head of a sheep, without feeling much resistance.

Feng Daiwen was very satisfied, of course, it is so good to equip soldiers with forging, but a blacksmith with two apprentices can only forge one a day, because it is too hard, the toughness is good, and it is not easy to form, Feng Daiwen mobilized 100 skilled blacksmiths to be responsible for forging, intending to form a commando.

There are no guns, if you want to fight with the Turks and want to reduce casualties, you can only prepare more, and if you are more prepared, you will leave a little less blood, the government soldiers who have rushed to Chang'an, under the strong request of Feng Daiwen, are full of three meals a day, as well as a large amount of mutton, pork, two meals a day with meat, the pigs and sheep in the homes of the people of the entire Guannei Dao have been bought to supplement the body of the government soldiers, and the generals are also training the government soldiers to death, and the government soldiers are trained to scream on the one hand, and they are secretly moved on the other hand, there are such good things there in the past, and there are two meals a day without war, The march had three meals but there was no meat, and meat could only be seen when the war began, and the current life could be said to be a fairy-like day for them. The hundreds of thousands of sheep harvested in Shuofang City were all killed except for lambs, wool was used for clothes, and mutton was given to the government soldiers to eat, and now there is no shortage of salt, and more of them are made into jerky, and the reserves are made into military rations, and the sheepskin is sewn into sleeping bags, and the soldiers are not afraid of the cold wind and wet clothes when they get into the sleeping bags during the march.

Shuofang Medical College is urgently teaching battlefield treatment, wound cleaning and bandaging, bone fixation, emergency hemostasis, wound suturing, is sutured with fine threads cut from sheep intestines, Taoist priests in the medical school have done experiments on injured people and animals, the effect is very good, Feng Daiwen secretly set up a laboratory under the medical school, let a few bold Taoist priests learn to dissect with Turkic corpses. This time, the medical school of 14 years old and above will follow the rear army to move together, Feng Daiwen was worried about the shortage of manpower and sent a message to Shuofang to recruit 3,000 people to follow the study and carry the wounded.

With the heavy snowfall, the new square city of Yankang Fang has been completed, and the people of the three squares have moved in, Yankang Fang uses all the bricks and stones, and the cement craftsmen have not yet experimented out, using yellow mud, clay, double row brick walls, and it is a large green brick, which is about the same size as the water spinach of later generations, which ensures safety and quality.

The first floor is the kitchen and living room, the bedroom, a total of three, the kitchen is connected to the bed under the bed that connects the bedroom with a brick passage, the bed is also made of bricks, it is a simple ondol, there are also three rooms upstairs, but there is no ondol, there is a yard in front of the house, there is a transplanted fruit tree in front of each house, one by one, close to the back of the river is another, the river is planted with willow trees, the river is also re-renovated with bluestone, clean and generous, there is a garden built in the center of the square, There are gazebos, stone benches, stone horses for children to ride and play, stone tigers, etc.

The people of Yankangfang moved into a new home, which can be said to be the envy of the entire Chang'an people, and the people who came to visit made the newly built and spacious streets once congested, and there were people who came to watch it for half a month, and the riverside and garden became a place to walk around several nearby markets. With the people who look at the fire kang is also slowly spreading, after all, it is simple, a look will be, hard work yourself will be made in a few days, the wisdom of the people is infinite, the rich will use the coal stove to burn the kang, almost the family will be connected to the wood fire, and the simpler is to build an earthen bed directly under the bed, and there is also a stove directly under the bed, and the gas outlet is installed outside the wall, because now we all know that carbon poison is the reason why it is not breathable.

Even many officials are envious of the renovation of Yankangfang, there are actually a few people on the book Li Shimin said that Chang'an City is too old, please renovate the library of ,,, Guang Defang has been built, occupying half of the city, in front of the visiting area and where the books are sold, is a row of connected two-story buildings, the first floor is the place for sales and other personnel activities, the second floor is where the books are stored, behind the small building is a garden, behind the garden is the new Bogu Hall, one side of the Bogu Hall is the printing room, near the river is a row of special residences for them, facing the river, Beautiful scenery. The rest of Guangdefang is still under construction, and it is a private house that Feng Daiwen intends to sell, and I believe that people who have seen Yankangfang will be very willing to come and buy it.

On the fifth day of the first day of December, there was no snow for many days, the people of Guannei Province were happy to take their wages, and the New Year's goods went home, although they were working in this cold winter, but they were very satisfied, not only the government gave the wages, and sent new clothes, it is said that it was still made of wool, and it was very warm, and two cans of canned sea fish, a pound of salt, and two pounds of sea vegetables were enough to have a hearty year. The entire Chang'an City was idle from the busyness, and only some people were still working for half a day.

This year's Chang'an City is very festive, all the people are smiling, not only everyone has money, but there are also a lot of cheap and delicious things in the world, delicious canned food, sea vegetables that can be eaten as salt, canned fruits that are sweet to the bottom of the heart, oh my God, such a sweet thing, I'm afraid the emperor will eat it like this, the five cents are too worthwhile, but unfortunately a family can only buy one can, my God, two cents a pound of refined salt is actually unlimited to buy, hum, fortunately only sold to the Tang people, Others can only buy a pound or five cents at most, the emperor list said that this is a New Year's benefit for everyone, the people of Chang'an are smiling and shopping on the street, the eldest daughter-in-law and the little daughter-in-law are carrying large bags of New Year's goods home, the children are chasing after their parents to ask for something to eat, and the elderly are basking in the sun at the door, revealing a big mouth with missing teeth and smiling wrinkles on their faces can kill mosquitoes.

Li Chengqian is the group of people who are not allowed to be idle in Chang'an, and followed Wei Zheng until the construction of Yankangfang was completed, and was thrown to Su Dingfang by Feng Daiwen with his two younger brothers Li Ke Li Tai, plus Fang Yiai, and brought to the military camp to train with the recruits, Su Dingfang had already been instructed by Feng Daiwen and did not give them any preferential treatment, although Li Ke and Li Tai were older, but after all, they had been exercising for so long, and they could barely keep up. Every day is spent in the desire to die, Feng Daiwen deliberately arranged for several of them to be together, Li Ke and Li Tai also lived up to expectations, helping Li Chengqian train together, and the three brothers shared weal and woe, so that Li Shimin, who had come to see secretly, was very satisfied, and he was very relieved that Li Chengqian continued to let Feng Daiwen teach.
