After listening to the little cat woman's narration, Jiang Xingchen immediately ran to the back mountain of Qingshan Village, and he wanted to be real again.

After this time, the people and craftsmen of the institute have cleaned up the area around the digester, buried what should be buried, swept away what should be swept away, and closed the lid of the well again. However, there was basically no wind in summer, and Jiang Xingchen could still smell the stench.

After feeling it a little, Jiang Xingchen immediately sensed that the pressure in the biogas digester was indeed several times greater than a few days ago.

Reopen the valve at the top, and a powerful jet of air erupts, all hissing against the pipes.

At this time, Xian Ning also came here to watch what Jiang Xingchen was doing, and he didn't mind the unpleasant smell at all.

"Xingchen, what is this thing for?" asked Xian Ning.

"Fuel! I'm going to use the gas produced by the fermentation of manure as fuel instead of charcoal!, but I don't know if it's going to work yet!" Jiang Xingchen replied staring at the gas outlet.

"Fuel!" Xian Ning was stunned, although engaging in science requires opening up his mind and making bold assumptions. But using the gas produced by feces as fuel still had a strong impact on her preconceived mind.

Speaking of Xian Ning, it was better, with the simple reality that Jiang Xingchen did last time, she could understand gas combustion.

But the group of students and a few children from the research institute who followed Xian Ning heard it for the first time, and their eyes widened in surprise, which was also too unbelievable. If you want to say that it is possible to burn manure directly, but the gas after fermentation of manure can burn, it is really incomprehensible.

Jiang Xingchen couldn't explain what methane was, so he could only wait for the results of the real yàn.

Just put more than a month of gas in this way, and Jiang Xingchen adjusted the valve. Let the air output decrease, and then find the velvet to ignite. Put it in the air outlet.

"Suddenly~" A small flame suddenly ignited from the gas outlet.

"It's done!" Jiang Xingchen swung his fist hard, and the smile on his face bloomed. That's when he understood. The manure fermented in the new digester starts to produce waste gas, which is useless at all!

"It really works!" exclaimed the students. What they thought was impossible, it actually succeeded!

Xian Ning's expression was solemn, and she found that her thinking was still not open enough. Looking back at the reality of what I have done in the past, the assumptions in many places are not bold enough. No wonder Jiang Xingchen said that science must make bold assumptions and rigorously verify them.

Turning around, Xian Ning said to the students, "Did you see it?" Many things that seem impossible to us can actually be done, and you should boldly put forward your own ideas in the future, don't be afraid of mistakes, and don't be afraid of being said to be whimsical!"

"Yes, teacher!" the researchers and students immediately responded, this real yàn really taught them a lesson.

After the students left, Xian Ning looked at the flickering flame and asked Jiang Xingchen, "What are you studying this fuel for instead of charcoal?"

Without motivation, production cannot be expanded. Many products can't be produced either!" Jiang Xingchen said, taking out a stack of drawings and handing them to Xian Ning: "Look at this!"

"This is ......" Xian Ning took the drawings and looked through them carefully, the more she looked at them, the brighter her eyes became. If this thing is designed. It was a revolution in production.

"Xian Ning, let's change places, the smell here is really not good!" Jiang Xingchen saw that Xian Ning was fascinated. Hurry up and remind.

"Ahh said: "Then go to my real yàn room!"

"Okay!" Jiang Xingchen casually closed the valve on the pipe, and the flame went out. The two of them walked briskly towards the research institute......

Meanwhile. The story of the old man and Zhao Danqing being blown out also spread, the Iron Sword Mercenary Group, the Bauhinia Mercenary Group, and the Song and Dance Troupe were all hilarious.

"Oh, it's a shame that the two of them were sprayed all over, I didn't see such a wonderful scene!" Mo Hongxian laughed while regretting missing this scene.

The gentle expression next to her is much softer than Mo Hong's, but the corners of her mouth that she has been picking are enough to show that she is in a state at this time, and she can't stop at all.

"Jiang Xingchen, this kid is too bad, even if the old man tricks him a few times, he won't use this way...... Hahahaha, no, I still want to laugh, when Lao Zhao comes back, I have to ask him, what is it like to be sprayed!" Mo Hongxian said loudly.

Wanrou hammered Mo Hongxian: "Pay attention to your image, see how you look like a girl!"

"It's okay, I can't help it, I think about the two of them full of ...... Poof!" Mo Hongxian hurriedly turned around, and her saliva almost sprayed Wanrou's face.

"Second brother, what do you think Zhao Danqing will look like when he comes back?

"Hehe!" the second brother will hehe now. He still has palpitations in his heart, his vest is full of cold sweat! He is grateful to the boss who has been bullying him, if the boss hadn't summoned him, he would be the one who is being sprayed now...... Damn, how can I see people in the future, I guess no one wants to share a table with me when I eat!

"No, I have to go to the entrance of the town and wait, these two goods may hide as soon as they come back!

The second brother complained secretly in the back: "Boss, do you want to mind being cruel! Are you like this, are your family man......?"

While Zijing was laughing at the same time, a group of members on Tiejian's side were also laughing and talking.

"I'm all convinced, have you heard, the boss actually fell into the pit!"

"It's really fake, don't talk nonsense, the boss is a big man, he will fall into the pit!

"Nier girl said, the little cat girl saw the boss with her own eyes, not what was in the pit!"

"It wasn't caused by falling into a pit, it was blowout......

"Blowout, what do you mean, how can there be a ...... Xiang"

"I've heard that's the case......"

"I'll go, so ruthless! poof!hahaha...... I'm laughing to death, the boss is too old!"

"And the old man, what do they think, it's okay to run to the back mountain and get up by yourself...... No, let me slow down first, my stomach hurts, I can't stand it!"

At this moment, the door creaked, and Mengyue, who had a straight face, walked in. The laughter of the group came to an abrupt end.

"Isn't it funny, isn't it funny that your boss was sprayed!" Mengyue asked.

"I didn't ...... No!" Don't look at these big men who are neither big nor small to Zhao Danqing, but they are all afraid of Mengyue. This is like having fun cleaning up the boss.

Although I didn't dare to laugh, I couldn't help it when I made up for the appearance of the boss after being blown out. They all pursed their lips, and their faces were red.

"Laugh if you want! Don't hold back, I couldn't hold back when I heard it...... Giggle...... "Mengyue said, letting out a silver bell-like laugh.

When she heard about it, she did laugh. But it wasn't Zhao Danqing who laughed at them, but laughed angrily. Why did I find such a thing, it didn't take a moment to worry. It's okay, what are you doing in the back mountains, where do you get so much curiosity.

Now it's okay, I've been sprayed, and I don't want to touch my mother in the future!

When Mengyue was so angry, Zhao Danqing shuddered violently, and an ominous premonition spread.

"Zhao boy, what are you shivering about, it's summer!" the old man asked.

"The clothes are wet, and of course they are cold on the body...... Old man, let's not go back!"

"No, I still have to find Xiao Soul Dan to take revenge! I sprayed us twice in a row, it's a great shame!" the old man shook his head resolutely.

"When will you take revenge, don't you have to be now, let people see ......"

"Do you think they'll forget about it after a few days! The people in the Xingchen Collar don't have any discipline, don't you know...... Think about it, what would you do if you were replaced by a little soul and was sprayed?"

"I'm sure I'm going to pull out this reason and hit him if it's okay!" Zhao Danqing said.

"Still, they probably think the same way!Zhao boy, since it is a knife to stretch out your head and a knife to shrink your head, then you still have to hide a fart......" Saying this, the old man waved his hand and said: "Don't worry, just be thick-skinned!"

As the two spoke, they had already arrived at the entrance of the town, and they saw Mo Hongxian, Wanrou, and the second brother waiting from a distance.

As soon as the old man said that he wanted to say hello, a group of people led by Mo Hongxian suddenly pointed at him and laughed.

"Lao Zhao, old man, you are simply a strange thing in the world today! It's the first time I've heard of being sprayed by Xiang...... Don't speak, I'll laugh for a while!" Mo Hongxian laughed.

Wanrou also covered her mouth, her shoulders kept twitching, and it was not difficult to imagine how hard they were sprayed at that time, and their whole bodies were washed thoroughly.

As soon as he came back, he was ridiculed, and the anger of the old man and Zhao Danqing jumped up. Is it so funny, you are so happy to see that we are unlucky.

The most infuriating thing is the second brother, how do you look like schadenfreude.

"What's so funny, don't you fucking pull Xiang, don't you wipe your buttocks?" the old man shouted angrily and strode towards Mo Hongxian and them.

But as soon as Mo Hongxian saw the old man walking towards him, he turned around and ran back, and he was scattered, and he disappeared in a blink of an eye.

"Uh!" the old man was stunned for a moment, and suddenly realized that the gang was disgusted with their dirtiness.

"Oh, I'm going!" the old man's forehead is bruised, let's all wash it heavily!" the old man yelled angrily. Originally, he said that he was thick-skinned and not angry. But he found that he really couldn't bear it.

Turning his head, the old man originally wanted to beckon Zhao Danqing to go back, but when he saw the goods, he picked up his clothes suspiciously.

"Damn! It's just a teammate like a pig!" The old man scolded angrily, flew up and kicked Zhao Danqing's buttocks, and yelled: "What do you smell, we just washed it!"

The two continued to walk inside, and every once in a while, they saw a few acquaintances, pointing at them and laughing, but as soon as they passed, they turned around and ran.

One group of people like this, two groups of people like this....... and finally at the gate of the lord's mansion, after seeing the crab also covering the wolf's mouth and laughing timidly, the old man felt that he was going crazy......!
