Author's words: Dear friends, I want to collect, collect, collect, collect, collect

The river kept pouring in from outside the cave, all the people were knocking on the rock wall, the tinkling sound had already attracted the piranha with a keen sense of hearing, and there were several schools of fish distributed around the rock wall, like a whole army of soldiers staring at the group of people who were banging on the rock wall, as if the river water was pouring in was an order, just wait for the river water to foam over the surrounding stones, they were going to kill the general.

Ji Lei watched the water level get higher and higher, and the fish were rippling on the stones, as if as long as a gust of wind blew, the fish could be pushed over, so he said: "No, the water level is too high, and the fish are going to swim over!" ”

An Li shouted loudly in everyone's voice: "Throw the saltpeter into the water in the direction we are going, and throw the rest with you as you go!" ”

As he spoke, An Li picked up the largest piece of saltpeter and threw it into the river, and everyone followed suit and threw the smashed saltpeter into the water. The sound of "poof, poof" attracted all the fish, and in an instant the river was filled with mist, and soon patches of strange fish floated on the surface of the water. There are many times more fish floating this time than when Hu Ting poured down the medicine.

"I said, Divine Doctor, is this fish dead? Don't fake your death like last time, right? Megatron also felt incredulous, but he still asked uneasily.

"Won't you go down and try it?" Hu Ting looked at the fish in the water and was not sure if they were really dead.

"Cut, I'm not going down" Megatron didn't want to be an experiment.

When junior high school chemistry class talked about saltpeter, the teacher once said that saltpeter can play a role in cooling down when put into water, and it has been widely used in ancient times, ancient people obtained saltpeter from dry soil, mineral springs, and cave walls, because saltpeter is infiltrated by water rich in ** all year round, so ice is formed after being put into water. At that time, An Li still admired the wisdom of the ancients, in the ancient times without air conditioning and electric fans, if there was no ice, it would really be impossible to live in the summer.

Therefore, An Li thought that as long as he knocked down the saltpeter and threw it into the water, the temperature of the river would definitely be lowered, and as long as the piranha lost its living environment, it would definitely die.

An Li looked at the fish turning over the belly of the river and knew in his heart that it should be dead this time, and at the same time knew that it was only the fish near the saltpeter that died, if he wanted to pass through here, he had to put in saltpeter, and take advantage of the sudden drop in the temperature of the river to wade through quickly, otherwise the temperature of the river was so high that it was not enough to cool down by the saltpeter that was smashed down. So An Li shouted loudly: "Bring saltpeter, hurry up and follow" and said that he was about to go into the river.

"Wait," Fu Hu saw that An Li was about to go into the water, and ran over anxiously holding the saltpeter, "It's better for the little monk to go down and explore first!" As he spoke, he rushed ahead of An Li and walked into the river.

"Tsk, monk, you really can, or how to say, if I don't go to hell, who will go to hell?" Megatron said admiringly.

Fu Hu got into the water, stood in the water for a few seconds, and then raised his feet to stir the surrounding river water, seeing that there was no movement in the river, the floating strange fish stared at the eyes, and the mouth with two rows of teeth was still motionless, and then nodded to An Li behind him.

Seeing this, An Li shouted to the people behind him: "Hurry up and keep up, the effect of this saltpeter won't last much time, everyone should hurry."

First Ji Lei and Hang Bangtian followed An Li into the water, then Li Yan and Hu Ting, and finally Hou Chun saw that everyone was going to the river, so he picked up the saltpeter that fell down and went to pull Wei Zhentian: "Brother Zhentian is gone, you see that they have all gone down, and the strange fish has not come, if you don't leave, when will you get the dragon fire order?" ”

Hearing the dragon fire, Megatron reluctantly picked up the two saltpeters that had just been smashed from the ground, and said, "If I am eaten by a fish, you will kill you"

"Okay, good, good, I'm harmful, I'm harmed" Hou Chun saw that he was finally willing to leave, and said helplessly.

An Li and Fu Hu walked in front and observed the surroundings while throwing saltpeter, and sure enough, there were still many fish in the river, but they were all around and did not dare to approach, An Li walked forward with them, and the fish also swam forward.

The saltpeter in the hands of An Li and Fu Hu has all been thrown away, but there are still three or four meters away from the cave, fortunately, the people behind and the saltpeter handed over, threw down the saltpeter and continued to move forward, the deeper the river went to the cave, the deeper the river reached An Li's waist, and the water temperature was getting higher and higher, the saltpeter was consumed faster and faster, and when the saltpeter in everyone's hands was about to run out, they finally walked to the cave.

Fu Hu suddenly stopped and couldn't leave, "What's wrong?" An Li asked.

"There is a rock wall under the river, you have to climb over it," Fu Hu said and jumped up with one hand supporting the stone wall in the water. Then he reached out to pull An Li, and An Li came closer only to find that the river was indeed a chest-high rock wall under the river, but it was flooded by the river and could not be seen.

"Hurry, hurry, the fish is coming" I don't know who shouted.

An Li was about to grab Fu Hu's hand and climb up, when he suddenly felt that he was being lifted up from behind, and An Li didn't care about looking back, only to hear Ji Lei shouting at Fu Hu anxiously: "Don't crowd at the entrance of the cave, hurry down" Fu Hu hugged An Li and the two quickly let go of the hole.

Ji Lei quickly climbed up with both hands and got out of the way, and the hanging bomb sky also followed, Li Yan ran over from behind, raised his foot to the stone wall of the cave, and put away his other foot. Hu Ting supported the stone wall with both hands and jumped up hard, and as soon as he felt that his strength was a little insufficient, he was dragged up by Ji Lei's two hands.

As soon as Hu Ting came up, Hou Chun and Megatron were less than two steps away from the cave, the water temperature slowly rose, and the fish that did not dare to approach also approached him, Hou Chunpu also seemed to have his hands on the stone wall as soon as he was picked up by Ji Lei and Hang Bangtian at the mouth of the cave, in fact, if Megatron could keep up quickly when he went down the river, he would definitely be able to rush over when the water temperature rose, and the fish would definitely not be forced over so quickly, fortunately, Hou Chun was more serious when he knocked saltpeter, otherwise they would have been torn apart by the fish.

The two saltpeters in Megatron's hand had already been thrown into the water, and the fish were getting closer and closer, and at the moment when Hou Chun was picked up, his hand also touched the stone wall, and his frightened heart finally calmed down, he thought that this time he was finally saved, and next time he would never dare to underestimate that girl. When Ji Lei saw him coming, he let go of Hou Chun's hand and dragged him.

Megatron looked at Ji Lei's outstretched hand and knew that it was his only lifesaver
