Zhou Nan smiled bitterly, he had no choice but to use arrows to make do with it.

He said to Cai Xianzhong: "Cai waits for the edict, pull out the arrow for this thing that is cast, and then insert the arrow shaft into the hole at the rear end of this object." ”

"The master of the village wants to use this thing instead of the arrow and insert it at the front of the arrow shaft, but?" Cai Xianzhong had a flexible mind, and as soon as he heard Zhou Nan say, he understood what Zhou Nan meant.

"Exactly. The middle should be empty, and the inside should be filled with gunpowder. Zhou Nan nodded and said, "Is it easy to cast?" ”

"It's easy, it can be cast overnight, and it will be baked tomorrow." Cai Xianzhong said affirmatively.

Zhou Nan put down the pattern and said, "This pattern is marked with size. It is best to have grooves on the outer shell, and the grooves are half the thickness of the shell. "Zhou Nan wanted this cast iron shell to kill the enemy with broken shell fragments when it exploded, and it was easy to explode with a trench, so he said a word to Cai Xianzhong by the way. After the test is successful, it is even possible to cast a wolf's tooth-like surface on the surface of the shell.

"The owner of Dazhai can rest assured. Zhu Xian is taking the two of them to burn charcoal, and I can make a few samples alone. Do not delay the owner of the village to use it tomorrow. ”

As soon as it got dark, Guo Xingzu stopped the work of several groups in the sulfur warehouse, all of them withdrew from the fence gate of the sulfur warehouse, checked the number of people, and knew that all of them had come out, so he locked the gate and went back to his room to rest.

Zhou Nan was very satisfied with Guo Xingzu's approach, and insisted on building a sulfur warehouse on this Nanshan Mountain, and even selected workers as long as they were carefree, just to minimize the damage of gunpowder to themselves. He said to Guo Xingzu: "When I find someone to come over tomorrow, you will list these procedures for preparing gunpowder, write them down on paper, and let everyone read them with you before entering the sulfur warehouse every day, so that everyone must not have an accident." ”

Guo Xingzu said gratefully: "Lord Dazhai, when the villain is in Beijing, where will Shangguan remember the life and death of the people below, but he just knows that he wants gunpowder." Connivance has a code of conduct that has been formulated, and it is also an ornament. There have never been T-shirt villains like you, the owner of the village! Zhou Nan held Guo Xingzu's shoulders and said: "Guo Zhizhao, you, me, and these workers, the soldiers on duty on the wall, we are all the same, we are all people, in Sanssouci Village, as long as you are willing to work and capable, no one will look down on you." When we make these bombs in the future, I, Zhou Nan, make an oath here: as long as Guo Beizhao's family is still there, I will be responsible for taking Guo Beizhao's family over, or Guo Beizhao wants to go home, I can also send you back, this sentence is the same for Cai Zhizhao and them. ”

Guo Xingzu's eyes were red, and he said to Zhou Nan: "If you can bring the little father, mother, wife and children, this little life is the master of the big village!" ”

Zhou Nan made a straight face and said, "If you can't take it, won't you Guo Zhizhao work hard?" ”

Guo Xingzu saw that Zhou Nan was unhappy, and hurriedly explained: "If you can't pick up the small one, you can also work hard for the big village owner, and the small one is happy......

Of course, Zhou Nan knew what Guo Xingzu meant, and Wen Yan said: "Guo Zhizhao, this sulfur library will be handed over to you, and these twenty-four lives, plus you, twenty-five lives, will also be handed over to you." Don't be careless. If you have few men, I will send you another man. When the bomb is finished, I will make you the head of the sulfur warehouse like Uncle Liu. ”

"The big village master, the small one doesn't want to be in charge, the small one only wants to follow the big village master and work hard for the big village master!" Guo Xingzu said excitedly.

"Just work hard, don't work hard - you come and see," Zhou Nan picked a branch casually, drew the same picture on the ground as the one he showed Cai Xianzhong just now, and then drew an arrow shaft in the back. Pointing to the picture, he said: "When Cai waits for the edict to be refined, the gunpowder is filled in, and the arrow shaft is inserted in the back, how to shoot the arrow at the enemy and explode?" ”

Although Guo Xingzu understood what Zhou Nan meant, that is, a special arrow was cast, filled with gunpowder, and it could explode after shooting at the enemy, then this arrow had both the accuracy of the arrow and the power of the bomb, and this arrow could be called an invincible arrow.

Thinking of the power of this explosive arrow, Guo Xingzu immediately became interested, and he imagined it on the ground, ignoring Zhou Nan.

Zhou Nan didn't bother him and left quietly. A skilled craftsman like Guo Xingzu, as long as you provide him with conditions and set the direction for him, he will surprise you with his own ideas, just like the wine bomb last time.

There is a faint red light coming out of the northeast corner of Nanzhai, which is the light of Cai Xianzhong's furnace fire for refining iron. In this early 12th-century Chinese territory, there are many places like an iron-making furnace in the corner of a cottage, where the fire of the Industrial Revolution is faintly burning.

In fact, in the Northern Song Dynasty of Xuzhou, Yanzhou, Xingzhou, Cizhou, along with the mining of coal, the iron smelting industry has been greatly developed, the annual iron output in the late Northern Song Dynasty is about 8 million catties, during the Yuanfeng period, as the official iron smelting retreated to a secondary position, the private iron smelting according to the "28 points system" tax, the result of the Yuanfeng period of the output reached more than 30 million catties.

The premise of the first industrial revolution was that machine production replaced manual production, and the premise of machine production was the production of steel and coal.

Zhou Nan always felt that in the Northern Song Dynasty, with a strong business atmosphere, relaxed production conditions, a large amount of coal and iron output, and the blessing of the world's most advanced science and technology culture at that time, it was very possible to embark on the road of industrial revolution. It's just that with the shame of Jingkang, most of the northern regions were included in the territory of the Jin State, and the Southern Song Dynasty lost a large number of coal and iron producing areas, and the industrial revolution was not to be thought about.

Now Zhou Nan just wants to rely on the bomb to fight for a piece of his own land, his own territory. As for whether to build guns and cannons in the future, it depends on whether the technology of this era is supported, after all, he is not a science student, and he knows the direction and general principle, but when he encounters specific problems, it depends on the technical reserves of this era.

Just like the last time without him, Guo Xingzu actually drummed up a trigger bomb.

"Report to the commander!" With an eager voice, a pro-soldier walked in.

Although he was very dissatisfied, Tong Guan also knew that there must be something important to report in a hurry at night. Tong Guan sat down in the seat and said to the soldier, "What's the urgency? ”

The soldier said: "The sentinel who went out to scout at night in the army just came back and reported that in the mountains on the west side of the river, there was a faint red light rising, and there seemed to be a colorful air in the sky. The sentry was only surprised, fearing that something strange would happen, and did not dare to hide it, so he came back to report. ”

A faint red light, a colorful atmosphere? Isn't that what the emperor has to offer? Tong Guan was also taken aback and said, "Hugh wants to talk nonsense!" Tell me that the sentry rider is brought in. ”
