Ma Xiangheng smiled proudly, and did not answer his words immediately, but turned to Professor Wang unhurriedly.

"Lao Wang, although we don't have a deep friendship, but we are all characters with heads and faces, I won't hide this matter from you, there is a very slow-growing creature parasitic in the Nagarjuna Tree, which I found when I first tested it. ”

"Creature? You mean that the black liquid floating on the surface of the water is all the kind of creature in the dragon wood?" Professor Wang was shocked, he had never seen a creature that could parasitize a type of wood for so many years, and it was so tiny.

Ma Xiangheng smiled and nodded, seemingly not caring about this matter at all.

"The surname is Ma, what do you mean by saying it now? Did you want to use these insects to kill us all here from the beginning?" Tang Yifei and Heizi were also shocked, and a little hairy, this is not a trivial matter, he and Heizi were the first to enter the river, although it was Lu Yunfan's suggestion, but Ma Xiangheng was the only one who knew the existence of this creature, so if you want to blame, you can only blame him.

But Ma Xiangheng didn't feel the pressure at all because their emotions were out of control, but laughed even more wantonly.

"Hahaha...... , what are you all doing in such a hurry, don't you want to wait for me to finish speaking?"

Tang Yifei pulled the sunspot who was about to go berserk, and was a little quieter, but the anger still did not disappear on his face.

Professor Wang was calmer, "Mr. Ma, could you please tell us what those microorganisms are?"

After he finished speaking, he also recalled the three words "microbe" in his mouth, and he didn't know if it was accurate to use these three words, because he was a biologist, and the definition of a biological being too general was a kind of non-rigorous thinking.

Ma Xiangheng said: "What kind of creature is it, I'm afraid that Professor Wang will personally study it, I am not good at it at the moment, but as far as I know, this microorganism will not be fatal when it enters the human body in small amounts, but it will produce some hallucinations, I guess, it should be an insect related to witch Gu." The insects grow very slowly and have a high mortality rate, but thanks to their strong reproductive ability, once they are parasitic in a substance, they will slowly enter a state of equilibrium after a sharp increase in numbers. This phenomenon is very strange, Professor Wang, it is better for you to study it on your own, it is still too rudimentary than what I said. ”

Professor Wang nodded, as if he had already understood this creature from his words, so he didn't ask any more questions, and said lightly to Tang Yifei: "In this way, you can rest assured that Xiao Lu and their safety are safe, you don't have to be too anxious, let's listen to Mr. Ma's understanding of Zhenlong Prison first, and we can better help us find a solution to them!"

Tang Yifeijue's Professor Wang's words made some sense, so he continued to press Heizi's arm to calm him down, and the two waited expectantly for Ma Xiangheng's words.

Behind them, there was a sudden sound of feet stepping on gravel, and several people who were overly nervous turned around almost at the same time.

Buffalo and Xiao Lun ran over and asked worriedly: "Brother Fei, what happened, why did the water here suddenly turn black, and there was so much less, and Boss Lu and Tie Han were all drowned?"

"Go, don't talk nonsense! Why didn't you stay on the side of the road, why did you all run down?"

"We're so worried, and we don't know what's going on, so let's come down and take a look!"

Tang Yifei no longer paid attention to the two of them, and continued to ask Ma Xiangheng: "Mr. Ma, is what Professor Wang said true?"

Ma Xiangheng sighed and bowed slightly, unable to tell whether he was nodding or sighing, so he immediately made Tang Yifei a little angry.

"Mr. Ma, you said it!"

"I have to think about this, don't rush me! I also saw this Zhenlong Prison on a blue and white vat from the Yuan Dynasty, and later after analyzing and some fragments of historical records, I confirmed this. ”

"During the Mongol period, Wokotai attacked the Song Dynasty and sent three soldiers and horses, one of which passed through here, and the general of the unified army at that time seemed to be called Dahai Xuanbu, when passing through a valley...... If I'm not mistaken, it should be here, after all, this kind of thing is still very rare, and as for whether the soldiers they led participated in this project, there is no trace of it. ”

Ma Xiangheng paused for a moment, looked carefully at the wooden Buddha that had already exposed most of his palm, and seemed to organize his words, and only continued after about two minutes.

"The pattern recorded on the blue and white vat is a sketch of the Zhenlong Prison, which uses the ridge as a cage and excavates two ends, one end and one tail, completely controlling the direction of the water flow in the mountain, although it seems simple, but at that time it was also quite a remarkable project! It's just that there is no clue related to the Buddha statue in the picture, so I was not sure at first that this Zhenlong Prison was related to the Zhenlong Prison built by the Mongol army, and the relevant details were not very certain, but since they entered the water, I gradually understood that Zhenlong Prison is the only one, and there is no second place in my country that is suitable for such terrain. ”

"Wait, Mr. Ma, I don't want to hear you tell stories, I just want to know how to rescue Lu Yunfan now, if you want to tell a story, let's wait for Boss Lu to be rescued and talk to him, we don't have enough time now!"

Ma Xiangheng looked at Professor Wang and pointed at Tang Yifei with a smile, "Hehe, you see that young people are anxious." ”

Professor Wang smiled awkwardly, but did not say anything about it.

"Xiao Tang, it's not something you can do in a hurry, I'm also for your good, there are such a large number of these microorganisms in the water, if we rush into the water, ninety percent of them won't survive, now we can only wait, wait patiently!"

"What are you waiting for?" asked Tang Yifei.

"Wait for the water to dry!" Ma Xiang pointed to the position of the Buddha's head.

"Did you see, after the water level dropped, all those microorganisms returned to the surface of the Wood Buddha, and they would continue to parasitize in the wood, my guess is this, the first point is that this town dragon prison is of course to control the riverbed upstream and prevent heavy metals from flowing down the mountain, and secondly, it is likely to attract these microorganisms and prevent these things from flowing down the mountain to harm people. As long as the water in the waterhole is completely dry, these microorganisms may not come out to harm people again, and then we can enter this wooden Buddha to find the entrance and rescue them!"

Tang Yifei frowned, although the water level dropped quickly, but he also had his own understanding of how high the height of the Buddha was, and when the water disappeared, it would be at least more than an hour later, Lu Yunfan and the others disappeared under the water, who could stay underwater for so long?

Although by now, they have been in the water for more than half an hour, and if they drowned, they would have already died, but people will always surface after they die, and Lu Yunfan and they did not come up at all, which corresponds to Ma Xiangheng's words.

"But if they're okay, where can they hide underwater?"

"That's why I let you listen to what I said, although it's not a bad thing for young people to be anxious sometimes, but sometimes you still have to hide and calm down and think twice!"

Ma Xiangheng seemed to be afraid of angering Tang Yifei, and there was a bit of evasion in his words, his consideration was not unreasonable, this is a wilderness, if this town dragon prison is really as he thinks, there are still some treasures left by the Yuan soldiers, maybe these two old guys will become destroyed corpses.

Therefore, even if he thought that he had persuaded Tang Yifei, he still had to pay attention to appeasing the emotions of the four of their brothers at all times, Lu Yunfan and Huang Lun were not here, and the four of them were the biggest force, and they could easily decide the life and death of everyone here.

Tang Yifei finally calmed down a little, "Okay, Mr. Ma, then you go on, what's going on in this Zhenlong Prison?"

Ma Xiangheng breathed a sigh of relief and looked at Professor Wang, but found that although this old guy was a few years younger than him, he seemed to be much deeper, and he didn't care at all about Tang Yifei's emotions that would explode at any time, and couldn't help but curse a few words about him, an old fox.

continued: "This town dragon prison actually uses an ancient water-lifting technology, storing water at the bottom, and then using strong water pressure to re-transport the water flowing through here back to the high point through a fixed channel, of course, there should be some siphon principle in this. It's well explained in modern physics. ”

"First of all, the water flowing down from the upstream has a strong impact itself, and this impact is better for the mechanism in this wooden Buddha, just like our modern hydropower station, but this water power is not converted into electricity, but directly as a force transformation, another part of the water is introduced into the channel of return. ”

Ma Xiangheng explained to a few people, and demonstrated with two hands, lest they couldn't understand, but the fact was that Tang Yifei and the others really didn't understand, they studied martial arts, not physics, and they didn't know anything about this so-called basic physics.

But he still insisted that at least Professor Wang could understand it, so that he could prove that he was not talking nonsense.

"This return channel will quickly introduce the water to the position of the end of the dragon's tail to achieve a cycle, but at the position of the faucet, the water is also trapped, and without the mechanism at the end of the faucet, it is basically impossible for the water to flow down spontaneously through the riverbed. Of course, you should also have a little bit of detail, the amount of water in the riverbed is very large, and it is not something that this small waterhole can accommodate, so I think that there is also an underground riverbed hidden under the above-ground riverbed, and Lu Yunfan and the others have been washed to the end of the dragon tail through that underground waterbed channel!"

According to Ma Xiangheng's explanation, Heizi crossed his two arms, wanting to demonstrate his words, and found that the end of the dragon tail in Ma Xiangheng's mouth seemed to be where they first stayed, so he bumped into Tang Yifei's waist socket in surprise.

"Brother Fei, I seem to understand, do you understand?"
