The dwarf was thinking quickly and had already vaguely guessed what Xu Zheng would say next, and his face couldn't help but look surprised and joyful.

Xu Zheng admired this very much. After many years of scientific development in his previous life, he thought of using it. Here he just mentioned it slightly, and the dwarf with a big head thought that this big head was really not a vanishing one.

Nodding at Sankke, he smiled and said, "You guessed it!"

"Ahha!" Sankek laughed happily, but did not reveal it, and listened to Xu Zheng continue.

Xu Zheng asked, "Let's talk about using it. Uncle Xius, what do civilians in the imperial capital usually use to make fire?"[

Xius said: "The firewood. Some civilians specialize in this business. They go up the mountain to cut trees and pick up skills. They can buy it in the city. Those who know a little can be burned into charcoal and then sold. I used to burn charcoal when I did business without a wildebeest carriage. Generally speaking, if I didn't have a way to get firewood, the money spent on it in a year is not a expense that the law would ignore."

Bruce nodded: "Aristocratic families generally rely on buying. With this kind of burned charcoal, it has less smoke and is more resistant to burning. Some people will buy coal to burn, but its output is small and the price is expensive. Human mining is far inferior to dwarves. Rich noble families will use fire magic crystals, which is very luxurious. The Samus royal family is rarely useful, and it is usually only used if the messenger comes to visit."

"Princess?"

Xingba Dai said: "Elf uses firewood all, no one else can do it! We can't play with fire magic crystals. I haven't seen what it looks like before..."

Ling Meimei said: "The use of dwarfs is half firewood and half black flint. Black flint is better used, and we generally use it in places with higher requirements."

Black flint is coal, Xu Zheng knows. In fact, Xingba Dai has seen coal because the raw material for Lingmei’s steam engine is it.

Xiao Chu said slowly: "One part of the beast tribe is afraid of fire. The other part uses fire and does not make fire. They are carefully preserved when lightning strikes a dead tree and produces fire. The ground is usually made of dead branches, leaves and dead grass. The tribesmen who could completely transform in the past few years learned to use fire from the human tribe." He sighed and said: "The life of the beast tribe is really backward. I only learned to make fire when I went to Zion."

Notting nodded slightly after hearing this, his expression was also depressed.

Camilla made several gestures to Xu Zheng. Xu Zheng understood that the fire in the abyss was probably used to make fire in the abyss. This is a cost-effective and trouble-free condition for the demon clan.

Pointing to the ground pipes on the ground, Xu Zheng smiled and said, "Now, we have better auxiliary materials for fire making and biogas. We lead it to various stores. Boil water, cook, keep heating, and do whatever we want. It can save firewood, trees, and magic crystals. Through these pipes, we can make good use of its properties that can burn and poison and pollute after burning." Xu Zheng didn't say other nonsense. For example, biogas is an efficient energy source, and no one understands it after saying it.

Sankek smiled and said, "I knew I was not wrong. But is it that useful?"

Xu Zheng said: "I can't guarantee this, because there is a disadvantage in the formation of biogas, it is very slow."

Xingbada nodded. This is because this gas in the swamp will not be available for a while and will accumulate for a long time.

Xu Zheng also said: "Because it is slow to generate. Normally, biogas utilization is a support type, and it cannot become the main focus. It completely replaces other lands like firewood, coal, etc. But its utilization can save expenses, which cannot be ignored. So I asked the teacher to add a catalytic magic circle. I think, with the power of magic circles and alchemy, maybe it can have a different effect in this time and space... Ahem, I mean Orson Manor, maybe it can have a different effect."

The group of people were very moved and said, "Thank you for so long, try it quickly."

Xu Zheng asked the three Balier brothers to work hard to inform each company to try it out. The security department, who had been merged into the production team some time ago, returned to everyone to assist in maintaining safety and preventing accidents.

Others chose Duoli's home as a pilot, and happily went all over her place, intending to open their eyes to see what Xu Zheng called the urban sewage system that everyone has worked hard for so long.

Bruce, Jimmy, and a few dwarfs have more knowledge and are more knowledgeable, and they can almost imagine what the entire system will look like when it works. But it is better to go and see it yourself and witness the new things in the Aristo continent with your own eyes. It is definitely a pleasure.

"Mom Notting, go and try it."[

"Can I do it?" Duoli was a little afraid. She was inevitably afraid of things that she knew about the Dharma. In addition, the beast tribe is a very backward tribe, and she doesn't understand and doesn't understand too many facts, especially after Xu Zheng made these miscellaneous things.

Notting was eager to try and smiled, "I'll do it! I'm not afraid of burning my hair."

Xu Zheng kicked him away and smiled and said, "Don't be afraid of our only eighth-class citizen. Just put the things you don't want in and break them too big, and don't block them."

The title of eighth-class citizen made Duoli a little proud and felt that she could not lose her confidence. She immediately walked to the sewage outlet.

There, there was a water tray, which was completed by the human potter. First, it was fired according to Xu Zheng's design, and it did not meet the standards in all aspects, but it could be put into use.

There is a lid at the bottom of the sink. Dori uncovered it, and there is a hole corresponding to the size of a lid below, the size of a fist. As soon as he uncovers the lid, he immediately hears a hissing sound deep inside.

Duoli was a little scared and took a step back. Seeing Xu Zheng looking at her with a smile and encouragement, she took the courage to pick up the broken vegetable leaves and throw them in.

The vegetable leaves fell into the hole, struggled for a moment, and were sniffed in with a sneer, and disappeared immediately.

Dori said in surprise: "Where did you go?"

"I sent it to the closest one of the eight big pits here."

"So fast?" Doli said in surprise and joy: "It's really magical, like a magical passage."

The fear faded, and he became interested in this convenient and interesting new thing. Duoli threw all kinds of unnecessary things in it. While watching them disappear quickly, she kept exclaiming: "What a magical pipe, so magical! You can eat anything, it's a good appetite. I never thought there would be such a thing before."

He kept throwing, kept throwing. Others found it interesting, so they also came up to try their hands and threw whatever they caught in. As a result, when Xingba Dai tried to throw the ground for the third time, the bracelet on his hand suddenly broke, and a gorgeous arc was drawn in the air, flashing a light in a more gorgeous figure and disappeared at the entrance of the cave.

All Petrochemical...

Xingba Dai flattened her mouth, smiled like crying, and said, "Brother did it for me... My father gave it magical blessing..."

Why is this happening? Xu Zheng was also arrived and quickly said to the prison: "I have to remind you that once the things fall in, they cannot be taken out. Be careful when using them..."

Sweat... I really deserve a beating when I said this at this time. Everyone was shot in their eyes, and Xingba Dai looked at Xu Zheng with sorrow. Xu Zheng wanted to drink poison and wipe his neck immediately and then jump off the cliff with the explosives in his arms.

A naughty little tiger jumped into the sink, snatched the hole and looked down. He stretched out his claws and dug it a few times, shouting, "It's so deep! You can't see anything. The elf princess has nothing to do.

He was quite excited...

Dori caught him in panic and threatened him, "Don't go over. You will be sucked in!"

Xu Zheng laughed dryly, "No, that little suction and sound are the result of the magic circle. Don't worry about accidents. The things in Xingbada are accidents... Haha... Haha, it's accidents..." He couldn't help but feel a little regretful when he said this, but he still didn't think about it thoroughly. He should leave a back door or something. If valuable things fall in, he can find a way to salvage them. But then again, in such an environment, to catch things... evil... I don't have to eat for a month.

Carlo looked at the hole and suddenly said, "You can make a net on it and leave the hole on the net. It's just smaller than the ring. The waste is broken first and then throw it in. In this way, you don't have to worry about accidentally falling into something valuable, or you don't have to worry about falling down the knife, it will definitely be blocked."[

Xu Zheng looked at Carlo in surprise and joy: "Uncle Carlo, you are so awesome!"

Carlo smiled: "I live many years more than you, and my life experience is much richer than you. Isn't as good as you, and this kind of thing that is closely related to life is still working."

Xu Zheng's face turned dark and said to himself: I spent two lives in total, it's true that I live many years longer than you. I'm just paralyzed in bed and have no accumulation of life experience...

Sang Duoduo grabbed his beard and looked at the hole for a long time, saying, "I have an idea to expand the idea of ​​this human uncle, add two layers of the net, and the lowest layer is what he said, and it can even make the hole smaller and cover a larger net with a hole opening to cover the entrance. The dwarf in the middle of the two layers of net can find a way to create a cutting mechanism similar to the size of the large pool, which is smaller and put it in the middle of the two layers, specifically for cutting items. Let their volume pass through the net below and enter the passage. Isn't the problem solved? In this way, you are not afraid of small things falling into it and not afraid of big things falling into it and blocking it. The best of both worlds."

Now, everyone turned to look at Sang Duoduo, which made Sang Duoduo feel furious and said dryly: "Uh... I often think about it, think I haven't said it..."

Sankeke shouted, rushed over and hugged Sanduoduo, and shouted in joy: "Brother, you are really strong! The number one genius in the clan!"

Also? This idea really works? Sang Duoduo looked at Xu Zheng in surprise and joy. When Xu Zheng made so many things, he seemed to have become the authority of invention and creation. Instinctively wanted to hear Xu Zheng's opinion. What the dwarf didn't know was that Xu Zheng was called standing on the shoulders of a giant, so he looked further away. A correct description was to describe it as a naughty plagiarism!

Now Sang Duoduo is looking forward to Xu Zheng's affirmation. Xu Zheng raised two thumbs to Sang Duoduo without hesitation and said, "Perfect!"
Chapter completed!
