The night was silent, the silence was silent, and the time slowly walked to twelve o'clock in the morning.

In an abandoned underground transportation station in Rongcheng, two shadows elongated by street lights appeared at the entrance.

"Brother Hong, are you sure that this place can lead to Shushan. Sun Yun stood at the entrance of the traffic station, and asked suspiciously.

"Boy, our beggar gang has been able to deal with Hongmen so far, relying on these transportation networks underneath, otherwise the boys who were bought by you this morning would have been caught by Hongmen. Hong Feng said proudly.

"Alright, let's go. Sun Yun nodded and motioned for Hong Feng to lead the way ahead.

The abandoned underground station is very quiet, and the sound of ticking water can be heard in the broken pipes from time to time, so it stands to reason that this station should be a very damp place.

But in Sun Yun's opinion, it was quite dry, in stark contrast to the humid air outside.

The two of them had just walked far when there was a sudden tremor on the ground that was very subtle, but could be felt.

At first, Sun Yun didn't care, but after walking a distance, the shock came again.

It's not obvious, but it's strange in the silence and darkness of the passage.

"Brother Hong, this is ......" Sun Yun patted Hong Feng in front of him and asked.

"Don't be afraid, when we discovered this place a few years ago, we studied the vibrations, and through the feedback from the thermal imager, it turned out to be a pipe full of hot water, and where it came from and where it leads, with the ability of us beggars, we don't know. Hong Feng said.

"Pipes full of hot water!" Sun Yun smiled, thinking in his heart, isn't this the heating pipe in our north.

But such a pipeline appears in the south, it is too abnormal, the weather in the south is pleasant, even in the cold winter, the lowest temperature will not fall below zero, where does this pipeline come from and where does it go? Will it have anything to do with Hongmen or the military?

Sun Yun suddenly remembered that it was mentioned in the history books that in order to maintain the balance of water resources in the north and south of China a few decades ago, the North and South Hongmen and the military jointly launched a huge project called the South-to-North Water Diversion Project, which shocked the world.

Sun Yun squatted down, his fingers touched the ground, and a dry and warm feeling spread to his skin.

"Brother Hong, do you think this pipeline will be related to the South-to-North Water Diversion Project decades ago? Sun Yun asked.

"Little brother, you are such a smart person to ask such a childish question, have you ever seen the south-to-north water diversion to transfer hot water? Let's go, it takes twice as long to take the underground passage to Shushan than normal, so don't worry about these inconsequential things. Hong Feng urged, Sun Yun stood up, and the two walked towards the depths of the passage.

As he gradually deepened, Sun Yun felt that the temperature was getting higher and higher, until he came to a three-way intersection, the temperature here had already made Sun Yun sweat.

"It was so comfortable. Sun Yun sighed with emotion and motioned for Hong Feng to stop and rest.

He glanced at the Beidou watch on his wrist and found that it was nearly 100 meters below sea level, and the temperature had risen to about 50 degrees.

"Brother Hong, martial arts are powerful, in such a hot environment, you don't seem to be the slightest bit uncomfortable, brother admires. Sun Yun flattered and sat on the bluestone bricks on the ground.

Hong Feng laughed, obviously very useful for Sun Yun's praise.

"Little brother, you're not bad, you actually came to a comfortable sentence in the 50-degree heat, and I admire my brother very much. ”

Sun Yun was just about to open his mouth to say about the defects of his body, but at the moment of exiting, he suddenly remembered the kind of eyes that Hong Feng showed when he was at the station, and said: "Big brother, don't you know, in our north, the floor heating burned in winter is almost this temperature, and I am an ordinary person, haha." ”

What Sun Yun didn't expect was that Hong Feng really believed it.

"I didn't expect that the winter in the northern land would be so cold, fortunately I didn't go to the north to develop back then, otherwise begging outside in this winter, unless we reach the realm of shaking the earth, we will also be frozen into stupid dogs. Hong Feng said with a big grin.

This sentence was said easily, but in Sun Yun's ears, he heard a trace of cattiness, going to the north to develop and beg, which means that there are also traces of beggars on the territory of Beihongmen.

However, when Sun Yun looked at Hong Feng, he didn't notice anything unusual, as if he didn't realize his gaffe, or he didn't care that he knew about it, or this guy didn't know his true identity at all.

Sun Yun shook his head, thinking about these unnecessary things now, it is tantamount to mediocrity disturbing himself, after pouring a big sip of water, Sun Yun stood up and said: "Brother Hong, we have been walking for more than an hour, almost three kilometers away, I don't know how long it will take to get to Shushan." ”

"Do you see these two forks in the road in front of you? Hong Feng pointed and said.

"Is there any difference?" Sun Yun was puzzled.

"The one on the left, at your speed, can be reached in about two hours, but if you go this way, the temperature will get higher and higher, and the middle section can reach more than 70 degrees, and this kind of temperature is no longer something you can bear. Hong Feng glanced at Sun Yun, and said with a chirp in his heart: Little rabbit cub, I am not honest with my uncle, I have never eaten pork and have never seen a pig run, and it can burn to 50 degrees by burning a heater, you think you are smoked old bacon in the village. ”

"Brother Hong, how about the right?" asked Sun Yun.

"The right side is good for you, but it's a five-hour walk away. Hong Feng explained.

This situation is not a choice for Sun Yun at all.

"That's naturally on the right, let's go, Brother Hong. Sun Yun raised his feet and walked towards the passage on the right, but before he could take a step, he suddenly felt a suction force from the backpack behind him, this force was very light, Sun Yun looked at Hong Feng and found that he was not aware of the abnormality at all.

The direction of this suction force pointed directly to the passage on the left, and Sun Yun couldn't help but have a burst of doubt.

"Could it be ......" Sun Yun guessed in his heart, and suddenly thought of the fur scroll he had placed in the middle of his backpack.

Sun Yun tried to take a step to the right, and the pull seemed to be a little stronger.

When Sun Yun immediately stepped into the right passage, the suction force instantly increased, and he was directly dragged to his feet.

"That's right. Sun Yun decisively stood up, patted Hong Feng's shoulder and said, "Brother Hong, how about we go to the left." ”

"On the left, you kid can't be crazy. Hong Feng looked at Sun Yunlai carefully in disbelief, this kid was wearing an ugly mask, no matter how he looked at it, he was a weak scholar with a weak personality, what did he want to do if he wanted to go to the left?

Sun Yun's mind turned sharply, and he came up with a set of arguments in a moment.

"Brother Hong, it's not a secret, in fact, I came to Shushan to treat the stubborn diseases on my body, in fact, I just said that the heating burns to fifty degrees, that's all nonsense, in fact, at a temperature of fifty degrees, the cold in my body has been alleviated a little, so I want to go to that higher temperature to experience it, if I can make the cold heal, it would be the best." Sun Yun said.

Hong Feng said indifferently: "You are the employer, everything is up to you, but if you kid is running the train with Lao Tzu in his mouth, be careful that I kill you, what Lao Tzu hates the most is the person who frames me." ”

Sun Yun smiled, didn't speak, followed the guidance of the suction force, and walked towards the passage on the left.

Soon after the two left, a figure appeared where the two had stayed before.

"There is a way in heaven for you not to go, and there is no door for hell for you to break into, damn boy, if you are roasted alive in that passage, then I will save myself the need to do it myself. ”

The person who came said something viciously, and then disappeared in the darkness and followed the two.

As the night deepened, the wind blew into the abandoned underground station, whirring, and as the wind blew, the frequency of the underground hot water pipes vibrated more frequently.

Especially in the position where Sun Yun was now, the vibration had reached a level where people could feel a slight shaking.
