Zhao Xie first came to the casting area, where the blacksmiths were wearing thin clothes and forging ironware, a technique that seemed simple, but not easy to learn.

According to the introduction of the Qing Bureau, the iron ore was mined in the Taihang Mountain, and then processed and melted into iron blocks locally, and then transported to various weapons workshops for use.

In the Weapon Workshop, the entire process of forging iron into weapons is included.

On the other side, there are forged finished weapons.

Zhao Xie picked up a sword in each hand, and slashed at each other violently, and both swords broke into a gap.

For the development process of ancient cast iron steelmaking technology, Zhao Xie has consulted in modern times, and has a certain understanding of this, this period of cast iron, is the use of block iron-making carburizing steel technology, to the middle and late Western Han Dynasty, the invention of steel frying technology, and then there are hundreds of steel-making and steel-filling technology.

In the future, we have to find an opportunity to inspect the site of iron ore processing and casting, and guide the craftsmen to improve the casting process under the premise of confidentiality.

After inspecting the casting area, we will come to the bow and crossbow area.

The first thing that interested Zhao Xie was stepping on the crossbow.

The so-called Tazhang crossbow, a bow that uses a foot to step on the machine and fire arrows, this weapon appeared at the end of the Warring States period, and the Qin army used the Tazhang crossbow to deal a heavy blow to the invading Xiongnu.

The most commonly used bow in ancient times was a bow that relied on arm strength to pull the bowstring.

The crossbow relies on the foot to pull the bow, which has higher requirements for the bow chord, and the leg strength is much greater than the arm strength, so that the arrows fired in this way have greater range and power.

As for the bed crossbow, it appeared in the Spring and Autumn Period and the Warring States Period, one or several bows were mounted on the bed frame, and the bow was loaded with arrows by twisting the wheel axle at the back of it, and it was fired on standby, and the range far exceeded that of a single bow and crossbow, but the accuracy was poor, the structure was bulky, the mobility was poor, and the tactics of large-scale salvo were generally adopted.

At present, the weapons that Zhao can make, the Han and Chu can also manufacture. Zhao Xie immediately thought of the Zhuge Repeater, if he could make it, he would have a weapon advantage in battle.

The craftsmen here were skillfully making crossbow machines, and Zhao Xie quickly discovered the problem. Before modern times, there was no such thing as an assembly line operation, and for the production of an item, it was often a single person who made the entire process, which was too inefficient and the quality was uneven.

In the horse farm, there is the head of the horse farm; In the armory workshop, there is also a person in charge, and there is also an official rank, and the official title is "engineer", who is in charge of all the craftsmen in an armory workshop.

After Zhao Xie entered the workshop, the engineer and the Arsenal Clearance Division followed him together, taking turns to explain the specific situation of the workshop.

"A man has to make all the parts of the crossbow and assemble the parts ......"

Zhao Xie pointed out the problem to the Qing Officials and engineers, and asked them to split the production process, take each part of the production as a process, formulate qualified standards for each process, and finally assemble it by a special person to standardize streamlined operations.

This does not belong to technical research and technological innovation, but to the innovation of the production model, just like the stirrup, which does not require much technical content, but lies in human imagination.

When the two of them heard this, their eyes lit up, and they praised this as a good method, saying that they would implement it as soon as possible.

Unconsciously, he had been inspecting the armory for a long time, and in the evening, Zhao Xie set off to return to the palace.

He wanted to go back and think quietly, think about the principles of ancient steelmaking technology that he had consulted in modern times, and then write them down and give them to someone he could trust to study and practice. In particular, it is entirely possible to master the steel frying method in a relatively short period of time and put it into use.

Back at the palace, Zhao Xie went straight into the dining room and prepared to have dinner with his beautiful wife.

The eunuch Ling Li Yan smiled and said, "King, the queen is happy!" He is currently in the dormitory. ”

My wife is pregnant! Zhao Xie was also happy after hearing this, and walked quickly to the dormitory.

In the dormitory, Qiu Ju and Xing'er were chatting with Zhao Qian to relieve boredom.

"The King Arrives ......"

As soon as the voice came, Zhao Xie stepped in and walked quickly to Zhao Qian.

Qiu Ju and Xing'er walked out of the dormitory with fun and closed the door.

In the dormitory, it is the world of the husband and wife.

Full of happiness overflowed on Zhao Qianqiao's face, and said gently: "King, the concubine hopes to give birth to a prince for you." ”

Zhao Xie shook Zhao Qian's jade hand and said: "Whether it is a prince or a princess, everyone likes it, I will find someone else as soon as possible to take over your paper mill, and you can also find a candidate." ”

Zhao Qian said: "It's okay, the concubine is just in charge of people and affairs, and she doesn't need to do heavy work herself, so it's okay for a few months." It's just that the concubine is pregnant and can't serve you for the time being, but if there is a suitable woman, let her serve you. You are a king, and you cannot have only one woman. ”

Zhao Xie couldn't help but sigh that women in ancient times were different, everything had to be for the sake of her husband's family and obey her husband.

After the two chatted for a while, they ordered someone to bring dinner into the dormitory, and it was freezing cold, so they no longer went to the dining room.

Li Zuoche personally led the cavalry all the way north, and every time he ran for a while, he would stop and rest for a quarter of an hour or two.

Where in the territory of Zhao was the army stationed? How many garrisons are there in each city? Who is the defender? Li Zuoche knows almost everything about this.

By evening, the snow had stopped, and the cavalry, who had marched more than 300 miles, came to a barracks, where the local guards had the soldiers set up new tents and cooked hot meals.

In the cold winter, in the era when there were no stirrups, Li Zuoche and the cavalry sat on horseback all day long, very tired, but fortunately they could have a meal at night and have a good rest.

The next morning, the weather began to improve, and there was occasional sunshine, and Li Zuoche led the cavalry to continue the march.

The Yishui River at the junction of Yan and Zhao is more than 20 miles away on the north and south banks, and both countries have garrisons, and sometimes there are scouts patrolling along the coast to guard against each other's invasion.

On the evening of the 26th, Li Zuoche rushed to the Zhao army camp on the south bank of the Yishui River.

The guard here is named Zhou Kai, and his military rank is captain.

"The last general will see General Zhengdong!"

Outside the barracks, Zhou Kai led his capital commanders and military commanders to salute Li Zuoche in unison.

After entering the barracks, Li left the lane: "How is the defense of the Yan army on the north bank?" ”

Zhou Kai replied: "After receiving the order, the last general ordered people to strengthen patrols and monitor the Yan army. As usual, the Yan army did not strengthen its defenses. ”

When the army set off, Li Zuoche sent a fast horse to deliver the news to Zhou Kai.

During the Zhou Dynasty, there was a special post system, in the territory of Zhao State, there were post stations at intervals, and the people who delivered the news changed their horses and ran again after arriving at the post station, and the speed was faster than that of the cavalry, and Zhou Kai received an order after nightfall yesterday.

On both sides of the Yishui River, there are watchtowers built at intervals between Yan and Zhao, which are convenient for observation and communication.

In ancient times, the river was a natural barrier to block the enemy's army, but now it is the middle of winter, and in the north of the central Zhao Kingdom, the rivers have frozen, and this barrier no longer exists.

I recommend a historical essay "Police Flower Chased Me to the Yuan Dynasty", a historical upgrade article worn by both men and women, which is really good.
