This marsh was formed by the upwelling of yellow mud from the ground, and the soil erosion of the spring water was serious, so that a large number of dead trees and grasses were buried under it, and the smell after fermentation was unpleasant in such a harsh environment.

Due to the diversity of the environment, this marsh is home to an amphibious plant called "hairy grass". Its vines have fluffy barbs that pierce into the skin of a person, and cannot be picked out with a needle, but as the muscles of the person contract, they penetrate deeper and deeper, and finally if they enter the blood vessels, they are not saved.

My father once mentioned this plant to me, saying that it can be cured by smearing the affected area with the sap of the "unicorn tree". An acid in the sap of the unicorn tree can penetrate the skin, acidify the barbs of the "hairy grass", and allow it to break down, and heal it with concentrated water when it is expelled from the skin.

Although I have never been pricked by such plants, I am obligated to tell them about the threat of these rare regional plants, lest they pay attention to the gorgeous appearance of the "hairy grass".

"Lingxin, Uncle Xia, look! These lilac plants, which are actually deadly, are called: Trichophylla. "Seeing that Professor Xia seemed to be curious about the only plants on the water, I cautioned him.

"Deadly?" Lingxin was obviously taken aback by my words and asked in surprise.

"Yes, its barbs will extend into the blood vessels when they enter the skin, causing them to clog!" I pointed to the tufts of hairy grass around them, "This aquatic plant is gregarious, and we are fortunate to be here this season, and if it is a little later, it will not work." ”

Hearing me say this, Professor Xia and Lingxin seemed confused, and Professor Xia was curious: "Sen, why don't I understand what you say?" ”

"Be careful, don't touch it with Penny." When answering Professor Xia's question, I noticed that Lingxin, who was holding a penny, almost hit the tuft of hairy grass with a bamboo pole, and immediately explained to them, "Uncle Xia, Lingxin, this hairy grass flourishes in the summer, and begins to wither in the late summer and early autumn.

"So when the vines turn yellow, the barbs of the hairy grass will flutter in the wind, and they will not be visible to the naked eye.

"It's still midsummer, so its barbs won't get out of it for a while, and if we're a month or two late, the air in this marshes will be mixed with a lot of fluffy barbs, and then when it enters the human respiratory tract, it will itch and suffocate."

"Sen, why didn't you say it earlier!" Listen to me and question me.

"It's not that I didn't say it earlier, but I just thought about it after I took a closer look. And don't you think it's strange?" After answering Lingxin, I suddenly realized that there was something strange about this swamp, so I asked them.

"What's not strange, don't divert from the topic!" When Lingxin saw me looking around, he shook his hand in front of my eyes.

At this time, Professor Xia, who also noticed that something was wrong, said to the two of us: "Lingxin, Sen, we have been rowing for so long, and every time we see that we are not far from Quanshan, but we are slowly pulling away. ”

At this time, Lingxin's expression was a little embarrassed, she put the penny down, took out her laptop to check our location, only to see a particularly conspicuous red exclamation mark warning pop up, the data analyzed by her computer was disordered, and then a series of code displays reloaded.

"Dad, Sen, the magnetic field here makes my computer unable to position, after I turned on the 'anti-resistance run', now the system is paralyzed, and it takes half an hour to complete the reload start." By the way, a series of operations just now, Lingxin explained to us. Obviously, there is a strong signal interference here.

I can't even help it, obviously the use of electromagnetic technology here is completely unworkable, so I can only use the traditional positioning - I give a thumbs up, survey the surrounding situation, and use our bamboo raft as the original center, and infer the anomalies of the surrounding scenery within the theoretical radius.

Finally I noticed that the distance between the east and west sides extended infinitely, in the form of a wavelength - a slight distortion of the surrounding things under the action of the air current. In such an environment, the occurrence of such a situation can only indicate one problem: there is a strange mirror image in this swamp.

At this time, when I was about to tell them the results of my deduction, Professor Xia seemed to have solved the mystery here, and he said to the two of us, "Sen, Lingxin, we seem to be stuck in a mirror labyrinth. ”

"Ahh Dad, how can there be a mirror image here! Ling Xin looked around, and after there was no abnormality, he questioned Professor Xia.

At this time, he saw Professor Xia's brows furrowed, thinking about the problem, so that he didn't hear Lingxin's words at all.

Seeing that Lingxin was very confused, I stepped forward to explain to her: "Lingxin, the surrounding environment here is very strange, under this scorching sun, it reflects and imitates each other, so here, the scenes we see are all illusory overlapping scenes, and there is only one real place. ”

Seeing that she was still puzzled, and when Professor Xia also asked me about the solution to this problem, I pointed around for them and explained: "The mirror principle is like putting many mirrors in a huge room, corresponding to each other, and a person or object is presented in these mirrors, but there is only one real one.

"However, it's more complicated by the various aspects of the outdoor environment.

"So, if we want to get out, we have to find the real route, or we'll go around in circles with the illusions around us."

"Sen, then you have to think of a way, if you continue to consume like this, we will all be sunburned." Ling Xin was no longer breathing well, and after saying that, he gasped for breath there greatly.

At this time, Professor Xia also seemed very helpless, because he may have never encountered such a situation, he has been engaged in archaeology for so many years; As for me, this is the first time I have seen such a situation, when I was playing against Uncle Zhang, he talked to me about this kind of interesting story, I don't remember the rest, it seems that I really have an impression about this.

It is said that the mirror image of nature caused by this environment is actually a special kind of mirage. The way to solve it is to find the reason for its formation, and the method of solving it varies depending on the geographical location and environment.

Therefore, I think that if you want to solve the labyrinth here, you must first analyze the environment here and what different strange phenomena may appear due to the environment, so as to determine where the exit of this labyrinth is.

"Sen, have you thought of a way, it's all up to you now!" Ling Xin's lips were already so hot that her lips began to chapp, and she looked at me weakly and said.

"I'm thinking. Listen to your heart, rest assured. We'll definitely get out. I replied. At this time, Professor Xia was sketching.
