Just as we were about to set off for the mountain, Lingxin's words caught our attention: "Dad, Sen, look! ”

Hearing her, we looked in the direction of her finger, and when we weren't looking, a thin mist was floating in the swamp.

"Sen, Lingxin, don't you think it's strange that this fog fills the entire swamp in the blink of an eye?" At the same time, Professor Xia, who also noticed this problem, asked us.

"It's really weird, I think it may be that after being scorched by the scorching sun, the surface temperature of the swamp was high, and now that night has fallen, the air flowing from the east and west sides of the marsh has formed a large temperature difference with it, so it will make the whole swamp fog."

I would like to analyze the situation based on the fact that the temperature difference between day and night in the mountains is slightly lower than in other places, and that the mountains here are low.

The two of them, who had no other good inferences about this phenomenon, nodded to me.

It was still hot in the air, but as night approached, the heat dropped sharply. There was an ancient road that ran through the east and west sides of the mountain before there was a swamp here, but now it is completely deserted, and when you look up, the loess road is hidden in the dense weeds.

Summer is undoubtedly one of the most headaches for those who venture into the mountains, suffering from mosquitoes and ants, and beware of snakes and wild animals, which is the most active season.

Along the recognizable path, we had a stick of wood with a knife to cut off the branches and leaves, and as we went, we struck into the grass; This is the so-called "scaring the snake" - it plays the role of driving away and avoiding being attacked by it.

Not every type of snake, though, is like this. There is a pit viper in this area, when it encounters danger, its retreat is attack, it thinks that only by resisting is the best way to resist danger, so when you encounter this snake, the more you provoke it, the more aggressive it is.

As it got dark, we took out the flashlights in our backpacks and walked along the crazy weedy path, looking for a place to set up our tents.

The bottle of mosquito repellent did work, and the mosquitoes did not dare to approach us. It is important to know that the biggest cause of malaria is mosquito bites.

Just when I was thinking that my luck would not be so bad today, and that I would come to whatever I wanted, there was a "hiss~" sound from the grass.

It was the sound that stopped us.

"Sen, is it a snake?" Lingxin whispered in my ear.

I nodded to him and looked at Professor Xia, expecting what he could do.

Professor Xia took the branch and measured it for me, and then his lips moved slightly, and his voice couldn't be quieter. In the end, I understood what he was trying to say: this snake hidden in the grass, about a meter long, is aggressive and poisonous.

As for the ability to know the length and attributes of snakes by listening to sounds, I think Professor Xia's ability may be a long-lost secret technique of "hearing sound and distinguishing shapes".

"Auditory sound discrimination", my father once mentioned to me, this auditory sound discrimination is a special category in Kanyu, and learners need a strong sense of hearing and smell. Because the mouth, ears and nose of the human body are interconnected, it is not a one-sided hearing acuity to learn this.

The snake in the grass refused to leave after we stopped, probably waiting for our next move, waiting for an opportunity to attack. It's just that its voice spitting poisonous letters makes people feel terrified to hear.

"Uncle Xia, can you catch snakes?" Seeing that the snake didn't mean to give way, I asked softly in Professor Xia's ear.

When I asked him if he would catch snakes, he shook his head helplessly. So I continued to say a few words in his ear, and then shouted "run", and Professor Xia quickly ran over. At that moment, the poisonous snake shot out of the grass, and when I tried to attack him, I grabbed it by seven inches and threw it into the grass in the distance.

"Sen! We made it! "After seeing that I had subdued the snake, Professor Xia bent over and gasped for breath and said to me.

Lingxin relieved himself about everything just now, ran to Professor Xia's side, and helped him: "Dad, what's going on, you were almost bitten by a snake just now!" ”

"It's okay! Let's talk as we go, or the snake will come back in a while! After Professor Xia said to Ling Xin, he looked at me, "Sen, you follow suit." ”

"Lingxin, just like that, Sen whispered a plan in my ear, I think it's a bit risky, but it's the most feasible," Professor Xia explained to Lingxin as he walked, "Sen said, the poisonous snake is hidden in the grass we are passing by, and if we rush to drive it away, we may be attacked;

"And the three of us ran over, and there was not enough time, and one of us was bound to be bitten by it;

"According to the snake's weak vision and the fact that it relies on heat sensing to attack its prey, Senna uses one person to draw it out and one person to catch its attention, I think it's okay - that's why there was the scene just now, but Sen's reaction is really fast, and even the speed of the snake can't match him!"

"Dad, why didn't you just give me a consultation, how risky it was just like that, do you know?" After listening to Professor Xia's words, Lingxin said angrily.

I came up with the idea, and seeing that Lingxin was so angry about it, I could only remain there silently and not speak.

After seeing my helplessness, Professor Xia explained to Lingxin for me: "Lingxin, don't blame Sen, he is also thinking about us. If I had told you just now, you would have stopped me, and I wouldn't have caught snakes at all, and besides, the longer we stay there, the more passive we become.

"For safety reasons, Sen's solution is the only way we can get out of danger, and I trust him very much, doesn't it prove it?"

After seeing Professor Xia say good things for me, Lingxin's attitude improved, and he looked at me and said, "Sen, the situation just now is really too dangerous!" You scared me, next time you don't have to decide privately, I'm also a member of the team, I have the right to know the plan! ”

Seeing that she was not so angry, I raised my hands and assured her: "Well, Lingxin, I will tell you next time, you are angry!" ”

"Sen!" At this time, Professor Xia looked at me, "What are you doing?" ”

"No, no~" I hurriedly put away my hand, "It's nothing!" Let's get on the road. ”

As soon as I finished speaking, I fell to the ground, my heart beating violently, and the ground trembled. The reaction made me feel like my whole body was about to be bounced.

"Lingxin, Senhe was bitten by a snake!"

Professor Xia reacted immediately; Then came a call from Ling Xin, "Sen-"
