Zhang Dashao frowned when he heard this: "Biogas, isn't that only in septic tanks and sewers?"

When Chen Ning heard this, he said that this kid really knows what biogas is, and it seems that it is not so easy to prevaricate.

"How is biogas formed?" asked Chen Ning.

"Biogas is a mixture of organic matter produced by microbial fermentation under anaerobic conditions. ”

"This is a forest, a natural oxygen bar, and there is oxygen everywhere and there are no conditions for the formation of biogas. Zhang Dashao's tone was very sure that the knowledge he had learned was only now coming in handy.

"If there are too many microorganisms that cover the surface of the object, will there be no biogas, and the weight of the biogas should be five thirds of the oxygen, so it will be close to the ground. Chen Ning's analysis was tightly organized, and Long Jiangtao nodded again and again while listening.

"You just tripped and fell and inhaled the methane, so you hallucinated about seeing what you were afraid of. ”

After listening to Chen Ning's analysis, Zhang Dashao nodded slightly.

Chen Ning said that this situation exists, and Zeng Jin's school teacher talked about a special case.

It was in the Amazon rainforest, where an adventurer tripped over a vine and never got back up, and at the time people didn't know what biogas was, so they called it "Dadesi" which meant that trespassers would die.

It wasn't until scientists discovered the existence of biogas that the phenomenon was scientifically explained.

After Zhang Dashao understood, Chen Ning also understood, and through his own explanation, he seemed to understand what was going on with the yin veins in feng shui.

It's just that science only explains a gas, while Feng Shui talks about pure qi.

After some explanation, Zhang Dashao's expression was a little gloomy.

Seeing this, Chen Ning stepped forward to comfort him.

"No matter what you see, at least you have overcome yourself, and if you have overcome yourself, why bother with the question of whether it is true or false. ”

"I understand the reason, but it was so realistic just now...... ”

Chen Ning patted him on the shoulder and said, "It looks realistic, otherwise how can you take a wooden stick and insert it into the root of the tree, I have to say that your kid's strength is not small." ”

After speaking, Chen Ning didn't forget to punch Zhang Dashao's chest lightly.

After some enlightenment, everyone continued on the road, and after walking for about an hour, everyone came to the top of the mountain.

The summit is a flat mountaintop, and the surrounding area is slowly approaching flat land.

Chen Ning judged from the flow direction of the aura that there were several springs under the top of the mountain where the water flowed, so the feng shui cave was generated.

Long Lao didn't even look at it this time, so he directly denied it.

"It's too high, it's too conspicuous, and there's no shelter everywhere, and it's hard to tell the direction of the wind, so it's really not suitable to move the grave. ”

Chen Ning nodded again and again, and then proposed: "Elder Long is getting dark today, why don't you come here first, and we will come back tomorrow to select." ”

"It's okay, I'm tired after walking for nearly a day, let's go back. ”

After Long Lao finished speaking, everyone began to prepare to leave.

Chen Ning found a high place, opened the eye of heaven and looked down.

The sky and the earth suddenly turned gray, and white lines appeared in Chen Ning's field of vision.

Chen Ning followed the line of the aura and began to screen the spiritual veins and feng shui eyes.

"Brother Ning, aren't you leaving?" asked Zhang Dashao behind him.

Chen Ning simply wrote down a few large acupuncture holes and closed the Heavenly Eye.

"Come on, the scenery I saw just now is very beautiful, and I can't help but look at it twice. ”

"It's good to look at it next time, and if you don't leave, we won't wait for you. After Zhang Dashao finished speaking, he went down the flat-topped mountain.

Chen Ning shook his head slightly and followed.

The crowd descended significantly faster than they did when they went up.

When passing by the biogas forest just now, Chen Ning obviously noticed that Zhang Dashao was walking on tiptoe.

Seeing this scene, Chen Ning lowered his head and smiled lightly, and didn't say anything.

When everyone went down the mountain, they saw Xiao Qi installing a spare tire on the car.

"Xiao Qi, what are you doing here?" asked Zhang Dashao.

Xiao Qi stood up and said hello to Long Lao, Long Jiangtao, and Chen Ning, but there was no Zhang Dashao.

Zhang Dashao didn't feel embarrassed, but asked again: "Why did you install a spare tire?"

"When I came back just now, I happened to meet someone stealing the tire of our car, and when I came back, the two people picked up a tire and ran away. ”

"I chased after it, and after running for almost three kilometers, I really didn't have the strength to come back. Xiao Qi slowly lowered his head and said in a deep voice.

Looks like a schoolboy who has done something wrong.

When Long Lao heard this, he didn't mean to reproach him, but only said, "You fix it as soon as possible, and strive to go back as soon as possible." "Then I got into another car.

Long Jiangtao followed Long Lao into the car, and he didn't rest on the way back, and the second elder was inevitably a little tired.

Zhang Dashao looked at Long Lao's back and couldn't help but pout, turned his head to Xiao Qi and said, "It's already very powerful, and I've chased for three thousand meters, if I can run eight hundred and die." ”

Xiao Qi ignored Zhang Dashao, turned around and continued to install the spare tire.

Seeing this, Zhang Da Shao smiled awkwardly, opened the door and got into the car.

Chen Ning took out a cigarette on the side and handed it to Xiao Qi.

Xiao Qi waved his hand and refused: "Mr. Chen, I don't smoke." ”

Chen Ning saw that he didn't smoke it, so he came to one himself.

After taking a deep breath, Chen Ning looked at the sunset on the horizon, and his heart aroused infinite emotion.

"The sunset is infinitely better, but it's just near dusk. ”

After smoking, Xiao Qi also finished installing the car, Chen Ning and Zhang Dashao drove a car, Xiao Qi went to drive a car where the two elders of the Long family were sitting, and the two cars slowly drove away from the eighteen ditches.

When I returned to the Changbaishan Hotel, it was already past eight o'clock in the evening.

After a hasty meal, everyone went back to their rooms to rest.

Lying on the bed, Chen Ning recalled today's events.

First, after waiting for a feng shui hole, he encountered this piece of poor and strange ink jade on his chest, Zhang Dashao was inexplicably hallucinated, and then there were the last two inappropriateness of the feng shui eye.

After brushing it again, Chen Ning sat up and took off his shirt.

The black jade went in and out against his skin, but he didn't feel tight at all, as if this piece of jade and himself were one.

Chen Ning tried to get close to this piece of black jade with his consciousness, but he didn't expect to be pulled into it by a suction force the moment he got closer.

After the world swirled, Chen Ning saw that there was darkness all around, that kind of substantial blackness, staying in it was like being in a black hole, and even the light would be swallowed up.

I couldn't see Chen Ning, so I released my senses and explored the way for myself.

As he walked, a light purple light appeared in front of him, and according to the usual routine, Chen Ning would definitely walk up.

So Chen Ning decisively turned around and turned back, so that he didn't touch this sudden thing, the so-called curiosity kills the cat.

Sure enough, as soon as Chen Ning turned around, he saw a light purple light not far away.

Then the entire space was filled with a lilac light.

Chen Ning sighed when he saw this, "I don't have a choice. After speaking, his feet were still sitting cross-legged on the ground, running his true qi, protecting his body.

He knew from the moment he was sucked in that it was a unique space, and he had to find a way to get out, so he walked around in it.

Suddenly, the entire space turned lilac, needless to say, Chen Ning also knew that it was the boss who came.

"I said, brother, why are you so cowardly, it's also the strength of the three grades of human spirits. ”
