After 12 o'clock at noon, the black rain in the mountains slowly dissipated, Qin Universe and Xu Liping packed their bags in the room, don't look at Qin Universe's usual big grin, in fact, he is very careful, mineral water, medical supplies, lighters and nothing are lacking.

Xu Liping looked at the things that Qin Universe had put in place, hesitated for a while, and still took out a bag of things from the dark compartment in his backpack. Silently stuffed it into the schoolbag, then took out a silver-veined short knife and handed it to Qin Universe.

"Brother, no! It's so polite, take it yourself! Hahaha. ”

"Take it, don't take me as a brother."

"Uh, okay."

Qin Universe said that he was very moved, the knife material is light, subtle and sharp, at a glance, I know that it is not a simple guy, Comrade Liping gave me the knife, what about himself?

Xu Liping had already packed his things, he glanced at Qin Universe twice, and signaled that he didn't have to worry, just set off...... Qin Yuyu connected the sheets, tied the foot of the bed with the sheets, and the two of them slid down from the third floor of the hotel, successfully avoiding the guard of Director Li at the door.

In order to prevent themselves from inhaling a large number of black spots, both of them were dressed tightly, wearing masks and eye masks. The place where the two of them lived was right facing the back mountain, and there was a trail in the back mountain, so they planned to go up the mountain from the trail......

There was nothing wrong with this mountain from a distance, but it was very terrifying when it looked closely, needless to say how strange the scene they had seen when they first went up the mountain before, and no one could see it clearly at night. But it was noon...... After a day of black rain, the whole mountain has already become lifeless, and there are several harsh and ugly strange cries from the mountain...... The mountain was still wrapped in a thick layer of fog, and there was a kind of irritability in the air, tsk, what a strange thing......

Xu Liping and Qin Yuyu turned on the flashlight and walked to the foot of the mountain according to the route...... This black fog is indeed a little thicker, and the visibility is only about 10 meters at most, both of them are cautious people, and it will not be a problem to walk well.

The path in the mountains is no different from yesterday, the black rain sticks to the plants, but for some reason, both of them feel that the soil on the ground is a lot softer, and the people are not heavy, but they can carry a large piece when they step on it.

"Liping, it's weird."

“？？？”

"What's wrong?"

"When I came here yesterday, there weren't so many flowers and plants here, and where did the plants in the mountains come from so many one-stalk and two-flowered flowers, and this phenomenon is more than half?"

Xu Liping didn't know, so he thought about it and continued to walk forward. Qin Universe followed behind, thinking about everything that happened today.

To be honest, when they climbed halfway up the mountain, they were confused and depressed. Because they saw a pool of stagnant water, and said it was a pool of stagnant water, but it was more like a giant jelly. Qin Universe threw a stone the size of a human head into the lake not long ago, but the stone did not sink immediately, but walked in front of Qin Universe and Xu Liping for a while before slowly falling......

Xu Liping turned his waist, took out a trekking pole from his backpack, approached the lake and dug up some lake specimens with an iron rod, and then handed it to Qin Yuyu.

Cosmos pinched the blue-green unidentified object at the top of the trekking pole with a glove.

"What's going on? Overnight, microbes multiply at an alarmingly fast rate. Qin Universe was puzzled.

"It is said in the book that bacteria can divide every 20 minutes, and can reproduce for 72 generations in a day, and if one does not die, the total number will reach 4,722 tons...... But this is not possible, because there are too many factors that affect the reproduction of microorganisms......"

“…… So what's going on now? Xu Liping asked.

"Bacteria proliferate abnormally, originally there was a certain amount of microorganisms on the surface of the lake, but after this night's mutation, the lake surface can be said to have formed a thick layer of biological clothing." Qin Universe replied.

The two didn't stay long, and in order to figure out what was going on, they had to hurry up to the top of the mountain...... There, perhaps, there will be the truth they want......
