The general is not only a benefactor who knows him, but also a comrade-in-arms who fights bloodily, and Zhao Wei does not need to consider it at all to choose between a court that only knows oppression and his own comrades.

For Zhao Wei's unhesitation, Zhao Kuo expressed his satisfaction, and immediately continued to instruct: "There is a lot of money spent on smelting iron and building soldiers. Especially if there is a shortage of grain, you can communicate with General Xu Li in the south of the river, and I will also ask him to help you greatly."

"Yes!" Zhao Wei agreed again.

"Also, about building troops." Zhao Kuo continued: "The feather arrows of the Qin army in my view are straighter and sharper than the feather arrows of our army, and they are sent farther and more accurate. And their arrows, shafts, and feathers are all named, and they should be made by different people, and if they are carefully considered, or for the benefit of the division of labor, we may also learn from them."

As a Zhao Kuo in the 21st century, he knows too well what standardized operation is. The improvement of its efficiency is not a little bit, and the military production of the Qin State may be the earliest standardized assembly line. If you don't study, you're sorry for your identity.

"For example, in the production of arrow shafts, wood selection, wood division, modeling, straightening, etc., or the steps can be separated one by one, and each step can be arranged for different numbers to be completed full-time according to its cumbersome degree, so that one person only does one thing, and practice makes perfect, and its speed is self-sufficient." Zhao Kuo went on to explain the so-called "division of labor".

"The most important step after that is to engrave the numbers on the shafts of the arrows made on different shifts, so that if there is a problem, the responsibility can be traced. The craftsman does not dare to take it lightly." Zhao Kuo continued to add.

"General, it's a good strategy." Zhao Wei knew the benefits after a little thought.

"This Qin people's Faer." Zhao Kuo was also rarely humble.

Immediately, Zhao Kuo continued to teach Zhao Wei face-to-face, after all, it is easy to defend the external enemy, but it is difficult to defend the internal tilt, especially Zhao Wei can almost be said to have no foundation, and Zhao Kuo is far away in Handan.

......

After some explanation, the moon has sunk in the west.

After eating the game from the guards, Zhao Kuo, who had been running all day, fell asleep heavily.

In the dream, the sun was shining, and Zhao Kuo was riding a high-headed horse, with a freshly baked hundred refining long knife in his hand and three thousand fine armor iron horses behind him, shining dazzlingly in the sun.

With a finger of the long knife, the three thousand iron horsemen followed Zhao Kuo's footsteps, like the collapsing river, in the darkness ahead......

When I woke up in the morning, my fatigue was gone. It's just that Zhao Kuo did not rush back to the camp, but taught the soldiers brought by Zhao Weihe in the valley to build blast furnaces, make corresponding blowers, and coking the coal mines.

Zhao Kuo can only rest assured that these high-tech technologies will be handed over to these people, even if they are built slowly, Zhao Kuo will never allow these technologies to leak out.

Together with the mud, together with the foundation, together to build the first blast furnace.

To be honest, although I was born in engineering and had basic theories, it is really not so simple to really build a blast furnace.

However, the blower was completed the fastest, and even the coking of the coal mine, a process that Zhao Kuo thought would have to be tested many times, was actually completed before the blast furnace was seen.

Fortunately, Zhao Kuo did not plan to build a blast furnace of much height, and finally after several collapses, a blast furnace less than two people high and the size of one person was finally erected - it is said to be a blast furnace, but it is better to say that it is an ordinary shaft furnace.

Of course, such a shaft furnace is enough for ironmaking, and a shaft furnace of this size is obviously only used to verify Zhao Kuo's method. One furnace of steel, let alone mass production, is probably only enough to make a short dagger.

But this could not stop the excitement of the crowd, and soon a carefully selected piece of iron ore was sent into the blast furnace.

The coking coal underneath is already burning, and Zhao Wei is also bare and agitating the blower to increase the air intake of the blast furnace to make the coking coal burn more fully.

There was no thermometer, let alone an observation window, so Zhao Kuo could only feel the burning of coking coal and the smelting of iron ore by touching the thick furnace wall.

Although the walls of the furnace are thick, they are still very hot.

This furnace wall

is much higher than the temperature of boiling water, Zhao Kuo, who was even too hot in boiling water in his previous life, but now he does not hesitate to touch it with his hand that has only wrapped two towels around, and it can only be said that this damn society really doesn't treat people as people.

Just once, the hand is almost gone.

Fortunately, the leader who was looking for the coal mine was originally from an iron background, and quickly helped Zhao Kuo come up with a solution: drip water on the furnace wall and judge the temperature at the rate of water evaporation.

Obviously, this is much more than Zhao Kuo's stupid touch of science with his hands. Zhao Kuo once again saw the wisdom of the so-called ancients. Looking at his scalded hands, Zhao Kuo really wanted to scold himself - pig brains!

It's just that even if there is a way to test the temperature, everyone still doesn't count which temperature is the most suitable. As a result, failure was almost predictable.

Fortunately, this question is not tricky at all. If you can't burn through, then burn it for a while; If you burn it too thoroughly, burn it less for a while; It is nothing more than a process of adding water to more noodles and adding more noodles with more water.

Under the day and night rush of the pro-soldiers, coupled with the assistance of the pro-soldiers who were born as blacksmiths, Zhao Kuo finally got the molten state he wanted after the fourth attempt.

Immediately, the mold was cast, demolded, and completed in one go, without waiting for everyone to observe carefully, the bright yellow iron ingot was put on the iron felt by the leader, and the sledgehammer and the small hammer fell in turn.

The clanging sound rang out all night.

With a "zila" sound, a dagger was finally freshly baked.

Zhao Kuo, who had not slept all night, his eyes were already red, and the surrounding soldiers were also staring at the blades created by everyone. It's a pity that the dark dagger can't see any difference at all.

Then I saw the blacksmith himself, holding the dagger in his hand, and putting the finishing touches on the whetstone.

A crisp sound of "......" instantly resounded through the valley, like the crisp sound of a dragon in the sky. Even those who don't know how to swords know that they have made a good sword!

Without the slightest hesitation, Zhao Wei, who had long been unable to hold back, nodded slightly, and then waved the sword in his hand, only to hear the sound of "dang", and the two swords slammed into each other, making a crisp sound.

Looking at the two swords again, above the long sword, a huge gap has been formed, but there is no trace on the short dagger.

"Good sword." Zhao Wei said in surprise, and then decisively threw away the long sword in his hand, and at the same time snatched the short dagger in the hand of his own soldier, and gently rubbed the smooth sword body with one big hand. Obviously, that long sword, but he followed Zhao Wei all the way through the future.

Use it like a treasure, and temperament like a disadvantage.

Oh, man......
