The dwarf's brain turned quickly, and he had already vaguely guessed what Xu Zheng would say next, and his face couldn't help but show a look of surprise and joy.

For this, Xu Zheng admired it very much, the scientific development in his previous life, how many years did he think of using it, and he only mentioned it slightly, and the dwarf with the big head thought of it, this big head is really not in vain.

Nodding at Sankike, he smiled, "You guessed it!"

"Aha!" Sankike laughed happily, but he didn't reveal it, listening to Xu Zheng continue.

Xu Zheng asked, "Let's talk about using it." Uncle Xiusi, what do the civilians of the imperial capital usually use to make fires?"

Hughes said, "Firewood." There are civilians who specialize in this business, go up the mountain to cut down trees, pick up dry skills, and can take them to the city to buy. Those who know a little bit will burn charcoal and sell it, I used to burn charcoal and sell it when I didn't have a wildebeest carriage to do business. Generally speaking, if you don't have the means to get firewood yourself, the money spent on it in a year is not an expense that cannot be ignored. ”

Bruce nodded: "Aristocratic families generally buy it, and with this kind of burned charcoal, it has less smoke and is more resistant to burning." Some people would buy coal to burn, but it was small and expensive, and Terran mining was far inferior to that of Dwarves. Wealthy aristocratic families will use fire-based magic crystals, which are very luxurious, and the Samuel royal family is rarely useful, and usually only uses them when envoys visit. ”

"Princess?"

Xing Badai said: "The elves all use firewood, and the others will not! Coal, I haven't seen what it looks like......"

Lingmei said: "The usage of dwarf is half firewood, half black flint. Black flint is better to use, and we generally use it in places with higher requirements. ”

Black flint is coal, this Xu Zheng knows. In fact, Starpadet has seen coal, because it is the raw material for the burning of the beautiful steam engine.

Xiao Chu said slowly: "Some of the beast clans are afraid of fire. The other part of the fire will not make a fire, and it will be carefully stored when the lightning strikes the dead tree to make a fire. It is generally used to burn the ground, which is generally dead branches, dead leaves and dry grass. A few years ago, the people who were able to fully transform learned to use fire from the Terrans. Sighed. He added: "The life of the beast clan is really backward, and I only learned to make a fire when I arrived in Zion. ”

Nordin nodded slightly, and his expression was also gloomy.

Camilla gestured a few gestures to Xu Zheng, and Xu Zheng understood that the abyss was about to use fire with fire. This is to save money and trouble, the unique conditions of the demon race.

Pointing to the above-ground pipes, Xu Zheng said with a smile: "Now, we have a better auxiliary fire material, biogas. Draw it to every house. Boil water, cook, heat up, whatever you want. It can save firewood and trees. Save Magic Shards. Through these pipelines, we can make good use of its ability to burn, and it is non-toxic, harmless and non-polluting after burning. Xu Zheng didn't say anything else. For example, biogas is an efficient energy source, and no one understands it.

Sankike laughed, "I knew I wasn't wrong. But is it really that useful?"

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

Star Badai nodded, yes, this kind of gas in the swamp is not a matter of time and a half, it has to accumulate for a long time.

Xu Zheng said again: "Because its generation is slow. Normally. The use of biogas land is a support-type existence, and it is unlikely to be the main focus. Completely replace other fields like firewood, coal, or something. But the fact that it can be used to save money cannot be ignored. So I asked the teacher to draw a catalytic magic array, and I thought, with the power of the magic array and alchemy, maybe it will be in this time and space...... Ahem, I mean Orson Manor, maybe it can have a different effect. ”

A group of people were very moved when they heard this, and they all said: "It's been so hard for so long, hurry up and try it." ”

Xu Zheng asked the three Balier brothers to be busy and go to inform the families to try it. Some time ago, the security department that was incorporated into the production team returned to each of you to help maintain safety and prevent accidents.

The others chose Dori's home as a pilot and happily went to her, intending to open their eyes to see what Xu Zheng called the urban sewage system that everyone had worked hard for so long.

Bruce, Jimmy, a couple of gnomes, all of whom are more knowledgeable and knowledgeable, can almost imagine what the whole system would look like. But imagine that it is better to see it for yourself, and it is definitely a pleasure to witness the new appearance of this Aris continent.

"Mother Nordin, go try it. ”

"Can I?" said Dori. It is inevitable to have a fear of what cannot be recognized. In addition, the beast clan is a rather backward ethnic group, and there are too many facts that I don't understand, and I don't understand, especially after Xu Zheng made these miscellaneous things.

Notin was eager to try his fists, and smiled: "I'm coming! I'm not afraid of burning my hair." ”

Xu Zheng kicked him away and said with a smile: "Our only eighth-class citizen, don't be afraid, just put the things you don't want in, break them too big, and don't block them." ”

The title of eighth-class citizen made Dori a little proud, and she felt that she couldn't afford to lose. Walk to the outlet.

There, there was a water dregs, done by the Terran potters. First of all, it was fired according to Xu Zheng's design, and it was not up to standard in all aspects, but it could be put into use.

There is a lid at the bottom of the sink, and Dori opens it, and there is a hole the size of a fist underneath that corresponds to the lid. As soon as the lid was lifted, a hissing and inhaling sound was immediately heard from the depths inside.

Dori was a little scared and took a step back. Seeing Xu Zheng smiling and looking at himself encouragingly, he was bold enough to pick up the chopped vegetable leaves and throw them in.

The leaf fell into the hole, struggled for a moment, sucked it in with a snort, and disappeared immediately.

Dori was surprised, "Where have you been?"

"Sent to the nearest of the eight pits. ”

"So fast?" said Dori, surprised and delighted, "It's amazing, it's like a magical passage." ”

The fear subsided, and she became interested in this convenient and interesting new thing, and Dori took all kinds of things that she didn't need and threw them in. While watching them disappear quickly, he kept exclaiming, "It's a miracle, it's amazing! I can eat everything, it's a good appetite." I never thought there was anything like this before. ”

Keep throwing, keep throwing. The others found it interesting and came up to try their hand at what they caught and threw into it. As a result, when Xing Badai tried to throw the ground for the third time, the bracelet on her hand suddenly broke, drawing a gorgeous arc in the air, and flashing with a more gorgeous posture. Disappear into the hole.

All petrochemical ......

Xing Badai flattened her mouth, smiled as if crying, and said, "My brother made it for me...... Father blessed it with magic......"

Xu Zheng was also arrived, and hurriedly said, "I have to remind you that once something falls in, you can't take it out." Please be careful when using it......"

Sweat...... It's a shame to say this at this time. Everyone shot a knife in their eyes, and Xing Badai looked at Xu Zheng's eyes with grievances. made Xu Zheng want to drink the poison immediately, wipe his neck, and then jump off the cliff with the explosives.

A mischievous tiger jumped into the sink and looked down at the edge of the hole. He stretched out his little paw and dug it in a few times, and shouted in his mouth, "It's so deep! Elf princess stuff doesn't

He's excited......

Dori grabbed him in a panic and threatened him, "Don't go over. Will be sucked in!"

Xu Zheng smiled dryly: "No, that bit of suction and sound is the result of the action of the magic array." Don't worry about accidents, things are accidents in Starbader...... Hehe...... Haha, it was an accident...... "Speaking of this, I can't help but regret a little, I still haven't thought it through, I should leave a back door or something, in case something valuable falls in, I can still find a way to salvage it." Then again, though. I went to fish for things in that environment...... Evil...... I don't have to eat for a month.

Carlo looked at the hole. He said: "You can make a net on it, and leave a hole in the net." It's smaller than a ring. Waste is broken up before being thrown in. This way, you don't have to worry about accidentally falling into something valuable, and you don't have to worry about blocking it if you drop a knife. ”

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

Carlo smiled: "I have lived many years longer than you, and I have far more experience in life than you." The ghost idea is not as good as you, and this kind of thing that is closely related to life is still working. ”

Xu Zheng's face darkened, and he said secretly: My two lives combined, it is true that I have lived many years longer than you, but I am just paralyzed in bed and have not accumulated life experience......

Sang Duoduo tugged at his beard, looked at the entrance of the cave for a long time, and said: "I have an idea, expand this Terran uncle's idea a little more, add two layers of nets, and the bottom layer is the kind he said, and even make the hole smaller, and cover it with a larger net to cover the entrance." The gnome in the middle of the two-layer net can find a way to create a cutting mechanism similar to the one in the large pool, which is smaller in size and fitted into the middle of the two layers, which is specially used to chop things. Let their volume pass through the net underneath into the passage. Isn't the problem solved? In this way, we are not afraid that small things will fall in and cannot be found, and we will not be afraid that big things will fall into them and block them. Best of both worlds. ”

At this moment, everyone turned their heads to look at Sang Duoduo, and saw that Sang Duoduo was furious, and said with a dry smile: "Uh...... I often think cranky, when I haven't said it, when I haven't said it......"

Sankike screamed, rushed over and hugged Sandodo, and shouted happily: "Brother, you are really strong!

Sang Duoduo looked at Xu Zheng with surprise and delight, after Xu Zheng had made so many things, it seemed that he had become an authority on invention and manufacturing, and he instinctively wanted to hear Xu Zheng's opinion. What the dwarf doesn't know is that Xu Zheng's name is called standing on the shoulders of giants, so the excuse to see farther is to change it to a bad and correct description, that is, **naked plagiarism!

Now Sang Duoduo is looking forward to Xu Zheng's affirmation, Xu Zheng did not hesitate to raise two thumbs to Sang Duoduo and said, "Perfect!"

Sang Duoduo's idea is really perfect, the entrance of the modern kitchen is this kind of structure of double insurance plus chopping and initial processing, Sang Duoduo used his own brain to think of this plan on the basis of Carlo, Xu Zheng can only admire.
