Of course, this iron pipe is not a chimney, and it is actually not iron but steel, but this can't be said! You must know that Yang Er, the Ministry of Industry of the Great Zhou Dynasty, can only smelt one or two thousand catties of steel every year, and if the five furnaces are fully opened in Shenmu Village, it is only half a year's amount to smelt with the steel filling method, and it can also ensure that each piece can be comparable to that of 100 steel.

Therefore, steel is not worth much in Shenmu Village, but if this lets Old Man Xia know that he uses steel to beat pipes, then he doesn't point to his nose and scold himself for being a loser?

The key is that if you let people know that you have mastered such an advanced set of steelmaking technology, you don't know whether it is a blessing or a curse.

After all, steelmaking and field making are two different things, the latter is a good thing for the people's livelihood, and the former is an important war resource and a major military event. Want to rebel?

Even if the court's kindness didn't make you a big crime of rebellion, but you will definitely not be able to refine this steel in the future, and you may be put under house arrest.

Because this technology is undoubtedly a black technology that can influence the war in this era! Around the Great Zhou Dynasty, there were Tuyuhun, Uighur and Tatar who were eyeing the Great Zhou Dynasty. There are ringing horses and bandits all over the mountains and fields in the Great Zhou, which of these people has this method?

When Wu Zheng took out the steel filling method, he just wanted to get a good one for himself, but after listening to Yang Er's this, his back was wet.

That's a scourge!

This is also why after Yang Er got this technology, the first thing he thought of was to sell his life as a slave, in which his thoughts of wanting to be famous for eternity were just incidental, the key was that he was afraid that Wu Zheng would kill him.

After all, they were the only ones who knew this method at that time, as long as they killed him, Wu Zheng himself didn't, then no one in the world knew about this steel filling method.

So even now, although many people have seen him use the steel filling method to make steel, except for the father and son and Wu Zheng, the others don't know what he is doing.

The method of filling steel seems to be simple, but the trick is in the ratio of pig iron to wrought iron and furnace temperature.

Just like a great master like Xia Lao now, he saw Yang Er's father and son making steel, but he still had in his heart because the two of them were just striking iron.

"That Xia Lao, if this fart can also be used to light the lamp, can you believe it?"

Xia Lao, who was watching Yang Er's father and son striking iron, was slightly stunned, looked back at Wu Zheng and said, "You can know what you want, don't use these words to disgust the old man." ”

"Ugh! This is actually the same as the people in the village, and the fart in their mouths is actually biogas. ”

"Biogas?"

Wu Zheng nodded and said: "That's right, it's biogas, but it's actually the same as a fart, it's all fermented through dung, it's called a fart in the stomach, and it's biogas in the pool." Of course, this gas can only be produced after large-scale fermentation, but also straw and other things can be put into the sludge. It's just that the most fermented dung in our village is still used for fermentation, not only by people but also by pig dung. ”

"You have a big on your left and another big, do you want to disgust the old man to death?"

"Ugh! Let's still be a lamp! There is one in the blacksmith shop of this lamp, and after Xia Lao saw it, he knew that he was wronged. ”

Xia Lao didn't know if he was really disgusted by Wu Zheng, but when Wu Zheng took him to see the lights, he wanted to see the waterwheel first.

In fact, there is nothing to look at this waterwheel, that is, a large water wheel is driven by water force, and then the power is sent to five lathes with gears.

Before, Wu Zheng and Yang Er wanted to get a stamping machine out, but the water on this mountain is still too much after all, and there is no strength after bringing the Wujia lathe, and if it is placed in the Qingshui River below, it may be possible to make one.

Yang Er thought that it would be more convenient and faster to have such a machine for making knives or farm tools, but Wu Zheng thought of only one thing, that is, bullet shells.

Although Errao has a different idea, the waterwheel at the foot of the mountain is already beginning to be built.

Because Yin Cao is here! With her experience and her own methods, I believe that it will not be long before the thunder mercury used as a primer will be sorted out.

In addition, Yang Er's technology for making seamless steel pipes has become more and more mature under his own pipeline project, and I believe that it will not be long before he can get a whole 98k out.

At that time, what martial arts master, martial arts master, I will be shot down from 800 meters away, and you don't even know who killed you.

Just when Wu Zheng was in a reverie, Xia Lao suddenly pointed to the lathe that was driving the pipe and said, "That's how your pipe came out?" ”

Wu Zheng subconsciously said without thinking about it: "Is there anything wrong with this?" ”

Xia Lao said angrily: "Haven't you ever thought of rolling out a tube out of iron sheets?" You have to hollow out an iron rod for a pipe, you have a lot of iron at home? ”

"This ...... This mainly involves a problem of air tightness, and it is difficult to report that each pipe rolled out with iron sheet will not leak. You must know that there is gas in this tube instead of water, in case there is a trachoma or something that cannot be seen with the naked eye, and the gas in it is flammable, if it cannot be sealed, it is a very dangerous thing to light the lamp at home.

In fact, this is not a waste, after all, the dug iron filings can be turned into iron pipes after returning to the furnace, and the cost is only labor, but there is not a water wheel! In fact, the waste of manpower is also limited. ”

After listening to Wu Zheng's explanation, Xia Lao didn't nod habitually this time, but looked at it for a while and asked again: "You spent so much time to get a tube out of it, is it really just for zero lights?" ”

Wu Zheng smiled: "Otherwise? ”

Xia Lao shook his head and said, "Your son has a bad stomach in his heart, and I know what the hell you are fighting this time." ”

"I know you don't believe that this thing can light like oil, but look there, that's the first biogas lamp I prototyped."

Xia Lao followed the direction of Wu Zheng's finger and looked at the second floor of the blacksmith shop, only to see that there was indeed a fire coming out of the iron pipe on the first floor.

Under Wu Zheng's instructions, Xia Lao followed Wu Zheng to the second floor of the blacksmith shop.

It is the second floor, in fact, the opposite side of the shop is the stockade, but there is a hurdle here, and the first floor is like a basement under the hurdle.

Knowing that Xia Lao was coming, the people who had gathered here earlier were all gone, including Yang Er, who was also hiding, and only his son Yang Er was still here with his apprentice to make nozzles and valves.

Coming to the fire, Xia Lao pointed to the flames on the horn and said, "This is your use...... A lamp lit with a fart? ”

Wu Zheng smiled: "Of course! ”

After Wu Zheng took another valve, the effect of the valve was not bad, and the entire gas path was sealed with only half a circle, and the fire on the nozzle was naturally extinguished soon without biogas.

Then Wu Zheng asked Xia Lao to see with his own eyes whether there was a wick on the nozzle, Xia Lao covered his nose and took a look, after making sure that it was just an empty pipe with nothing, Wu Zheng opened the valve again, leaned on the nozzle with a fire fold, and before it reached the nozzle, the flames popped.

Xia Lao looked at this flame and secretly exclaimed, can this fart really be used to light a lamp? 166 Reading Network
