Through the gas mask, Suo Yang also saw the green gas spit out of Wen Xin's mouth, but he did not show the surprise that Chang Sheng imagined, but his face was calm.

Chang Sheng asked in surprise, "Aren't you afraid?"

Suo Yang asked inexplicably, "What are you afraid of?"

Eh, is it because Suoyang's heart is too big, or his ability to bear it is not as good as a child, Chang Sheng is a little confused by Suoyang.

Chang Sheng asked again with confirmation, "Didn't you see the green gas coming out of Wen Xin's mouth?"

"See!" Suo Yang said as a matter of course, "Isn't this weird? Isn't everyone like this? I vomit from time to time." With that, Suo Yang ripped off the gas mask and complained, "I thought it was all the rage." ”

"Huh?" Chang Sheng said incredulously, "You're going to spit this green gas too?"

Suo Yang nodded very seriously and said, "This kind of thing is very common, isn't it?

Chang Sheng's worldview collapsed in an instant, and he asked Suo Yang in a trembling voice: "This kind of thing is very common?"

"Yes, I, Wenxin, and everyone at the base have always been like this. Suo Yang suddenly reacted and asked, "Isn't this an ordinary thing?"

"Of course it's not ordinary!" Chang Sheng immediately said: "Normal people...... No, the word is wrong, it should be said that healthy people don't breathe green!"

This time, Suo Yang's expression on his face collapsed, and he was stunned for a long time before he spoke.

Suo Yang said that he had always thought that this situation was normal, after all, when he and Wen Xin were locked up in the base, and when they were taken out of the cell from time to time, they could also see other people spitting green gas like them, and they were both too young at that time, so they would take the situation of everyone around them as common sense.

Later, when I came to the city of freedom, it didn't happen very often, and most of it happened in the early hours of the morning, when everyone was sleeping, so I haven't seen others spit green gas for more than a thousand years, and Suoyang didn't feel strange, let alone suspect that it was abnormal.

Chang Sheng nodded knowingly, and asked, "Did you all hear it?" Weiwei, you said that Wenxin's illness can't have anything to do with this green gas?"

"When the flu virus is flying all over the sky, not everyone gets the flu. Wei Wei said: "Personal physique also has a great impact, in short, Wen Xin's illness is directional, this discovery is a good thing, just wait to return to the alliance, I will do a precise physical examination for the two of them, and then study the solution." ”

Wen Xin vomited green gas for a total of five or six minutes, and then she returned to her normal state.

The green qi floated around Wenxin, and in just a few minutes, they quickly grew to the size of fingernails, taking root in the cracks between the ground and the stone wall.

Ten minutes later, the entire walls, roof, and floor of the stone chamber were filled with glowing fungi, and there were many small glowing particles floating in the air.

Now Chang Sheng understands the reason why Suo Yang, Wen Xin and the mysterious big sister, as well as the unconscious masked man, only stayed for one night, and the passage was full of glowing stones, it turned out that these glowing stones came from like this!

However, the mysterious big sister said that she did it, and she herself had this problem.

Chang Sheng found that even if he sat still, those glowing fungi floating in the air would stick towards him, but Suo Yang next to him and Wen Xin, who was sleeping soundly, had no such troubles at all.

I can't imagine that even fungi can meet people to serve dishes here, what a strange place! Or maybe ...... The strange thing is that those two children are not necessarily.

In order to prevent unnecessary trouble, Chang Sheng still sent them all into the Void Space according to the method last time, and only then did he relax a little.

At this time, Wu asked worriedly: "Master, don't you need to wear a gas mask?"

Chang Sheng smiled and said: "It's too late for you to give this advice, right? You can rest assured, my body is invulnerable, and I also use your energy to flow with spiritual power in my body, I don't believe that this fungus is so good, even the power of the other world can withstand it." ”

"You don't have to worry about this," Li Han said: "Even if you can withstand the power of the other world, you may not be able to withstand the power of the key, and there are few physical bodies in the world that can withstand the several energies in your master's body, let alone a small fungus." ”

"That's it, don't worry about me without you. As soon as the conversation changed, Chang Sheng was puzzled: "I remember that the innkeeper said that where Suoyang and Wenxin live, the people around them will be infected with the disease of Wenxin, do you think it will have anything to do with the green gas they vomit?"

Lao Tao replied without hesitation: "Very likely!"

"But ......" Qian Mixin said suspiciously: "As long as the two little ghosts leave, they will be all fine soon, why can't Wen Xin see well?"

Weiwei said that this may have something to do with the time of infection and the stage of the disease, maybe in the early stage, as long as you stay away from the source of infection, you can be cured naturally through your own resistance or some external factors, obviously Wenxin has missed the best period of natural recovery.

External factors?Thinking back to all the places where the luminous fungus appeared before, plus what he had seen and heard in the past few days, Chang Sheng's mind suddenly flashed with inspiration.

"I think one of the most important external factors should be sunlight!" Chang Sheng said in an almost affirmative tone: "This is also one of the important reasons why Suoyang and Wenxin have lived in the stone forest for so long, but they haven't seen a single luminescent fungus around! ”

"This idea is interesting and rigorous, and it can be used as a direction for in-depth research. ”

Qian Mixin asked unconvinced: "Many fungi avoid light, why do they have to refer to sunlight specifically?"

Chang Sheng said: "I believe you also have the picture of the corridor, the brazier in the corridor is enough to explain the problem, if you really avoid any light, these glowing fungi will not grow in this corridor at all." ”

Quan Quan praised: "Makes sense!"

Chang Sheng believes that these luminescent fungi need an environment that is completely protected from sunlight, as evidenced by Suoyang and Wenxin's stone nest.

The stone nest where Suoyang and Wenxin live can be exposed to sunlight for a short time in a day, which is very suitable for the survival of light-sheltering creatures, judging from the number of spores that Wenxin spits out today, the lack of a single luminous fungus in that stone nest is enough to explain the problem!

In other words, they can't withstand even a little sunlight, not even a single corner of the stone nest that can never be exposed to direct light grows, which shows that they can't even withstand diffuse reflection and short-term weak light.

"That's the main reason why I've always wondered why I don't see a single glowing fungus in Liberty City or in the Stone Forest," Chang Sheng said. ”
