"Who are those people?".

Cheng Hao shook his head and said: "I don't know." Bai Chi was surprised at the moment and asked:

"What if he's one of your people? Or if he's just an acquaintance and shakes hands, we're still good friends."

Cheng Hao still shook his head slightly and said with a smile:

"I have been in the abyss for so many years! What friends do I have?"

Seeing that Bai Chi still wanted to ask, he said again:

"Intuition questions, these are ruthless characters. Bai Chi, the question about the second master is very complicated. When the time comes, I will give you a satisfactory answer. You have to consider the immediate problem first. You need to take a rest first. There may be a fierce battle later.

…”

Since Cheng Hao said this, Bai Chi was sure that Bai Ping was lying before, but he didn't understand why he was contradicting himself. He could only nod and said: "Okay!".

Although I am not particularly interested in the Sixth Sense, and I really want to ask the second master about it, and I even keep guessing about the purpose of their trip. But looking at the faces of the two people, I can tell that the problem at hand is a bit serious.

Bai Chi went back and sat down on Bai Ping's legs.

Liu Wei was worried and asked: "If we stand so high, people coming in from behind may not notice us."

"They will definitely find this place." Cheng Hao stood upright and said without looking back:

"Marks on the ground will give away our location."

Liu Wei frowned and said, "I have to think of a way..."

The two of them were talking about something, and Bai Chi and Bai Ping were not idle either. Bai Chi blocked it with his body and wrote in Bai Ping's hand: "Be careful now."

Bai Ping thought for a moment and replied: "According to circumstances! I am much better now, and I will protect the safety of the clan leader."

Bai Chi frowned and glanced to the east. He could vaguely see the edge of the cavity. He suddenly remembered what Liu Wei said before and asked, "It's not far from the east. Can we go out?"

This time Liu Wei answered quickly: "Not sure."

Bai Chi turned around and glared at Liu Wei. Liu Wei smiled at Bai Chi and mouthed silently: "Don't worry."

Will Liu Wei's plan this time be consistent with Cheng Hao's purpose? What mysterious thing makes so many people obsessed with it? Whether it is the former second master, or the current Liu Wei, Cheng Hao and others

, obviously spent a lot of thought on this matter. The whole incident seems to be shrouded in countless intricate and intertwined dark threads. From the clues discovered, it can be seen that someone has been secretly planning thirty years ago or even longer.

At this time, Liu Wei and Cheng Hao seemed to have discussed some countermeasures, and they also retreated and sat down together.

Bai Chi glanced at the two of them and asked, "What are you going to do?"

Bai Ping also straightened up and propped up his ears. Cheng Hao drank some water, wiped the corners of his mouth and said:

"wait……"

"What are you waiting for?"

Bai Chi thought for a while, stared at Cheng Hao and asked tentatively:

"The purpose of these people below is the same as yours?"

"I don't know either!" With Liu Wei's experience in the world of martial arts, he clearly understood the intention of Bai Chi's cliché, and avoided answering Bai Chi's subsequent questions, saying:

"Take a step and see what happens!"

Bai Chi nodded. Seeing that he was free at the moment, he picked some questions that he felt Cheng Hao would answer: "Is that geological fissure poisonous?"

"crack?"

Bai Chi explained: "That's it..."

"We call it the Netherworld Ancient Road..."

Cheng Hao's hair fluttered in front of his forehead. He turned to stare at Bai Chi and said, "The road leading to the Netherworld... is the small pit that Bai Ping fell into earlier."

Bai Chi was shocked by Cheng Hao's serious call. It felt very appropriate but also carried a sense of fear that could extend infinitely.

"It's not just poisonous gas, there's something even more terrifying."

"Oh?" Bai Chi asked quickly: "What else?"

At this time, Liu Wei interrupted: "Only ghosts know this."

Bai Chi turned around and asked Cheng Hao:

"Didn't you say it's scarier down there? There's nothing there, so how can it be scary?"

Liu Wei couldn't wait to interrupt and said:

"There's something barking underground, so it's not stable!"

Bai Ping glared and shouted: "Speaking of human words, what on earth..."

"He said that there are ghosts screaming in the ancient Nether Road..." Cheng Hao replied coldly.

After Cheng Hao finished speaking, he stood up, patted the dirt on his body, and said:

"Gone."

The four of them were just about to leave when they heard a ethereal sound in the darkness beside them. The sound was far away and could not be heard. Bai Chi stopped and glanced over, only to see that he was about thirty years away.

A few meters away, clouds of white smoke gradually floated out.

The smoke rose and billowed, gradually getting thicker.

Liu Wei was stunned and immediately shouted: "The smoke is coming from the cracks in the ground."

Baichi took a closer look and found that there was a black crack mark at the bottom of the mist, which gradually appeared against the white mist.

Another geological crack? What is going on in this ghost place? Huge underground cavities and unfathomable geological cracks are both geological wonders, both of which are extremely rare. The two phenomena appear together at the same time

, some coincidences are too much, there seems to be some kind of connection between them.

Moreover, the crack must be formed before the cavity. Otherwise, if the earth's crust moves to create such a deep crack, the cavity will definitely collapse, and the immeasurable weight of the top of the mountain will collapse, forming a huge pit.

At this moment, Cheng Hao hesitated and said:

"Bai Chi, let me tell you something now. There is an underground base here from the last century."

Bai Chi was stunned for a moment and asked: "What kind of underground base?"

"It is the base of the Japanese Kwantung Army. This base is built under the ancient tomb. Not far away is the corridor of the base. If I think so, I should let you know."

Cheng Hao replied lightly.

Bai Chi hesitated for a moment, but still didn't say anything! Sure enough, not far away, he faintly saw a passage-like corridor and a huge building...

As soon as the four of them walked into the corridor, they took a general look at the nearby environment. The Kwantung Army's underground facilities were very complex. As far as this concrete building with giant cracks was concerned, it was unknown how much manpower and material resources were needed to build it.

"There should be an old-fashioned generator here! Look for it!" Cheng Hao said.

The generator Cheng Hao mentioned is in this building. Based on Bai Chi's inference, the generator that can operate for such a long time should be a water flow generator, and there should also be a main underground river in this underground cavity.

The continuous flow of the river is probably the underground river that we passed through before, and the underground river changed its course during a period of changes in the crustal movement.

After a while, Cheng Hao lit the generator, but the four of them discovered a disinfection locker room and a bunch of pipe facilities. There were chemical protective suits in the disinfection room. In other words, there was probably some kind of poison inside.

Hazardous facilities with radiation or toxic gases.

But at this time, a half-human scream came out of the pile of pipes. Bai Ping ran over to be on guard, and Bai Chi also followed.

When the four of them chased them into the pipe, they didn't even see a ghost.

At this time, Baichi felt a sharp sting in his throat, and knew that he was about to encounter poisonous gas. At this time, the generator also stopped running, and the lights above his head became much dimmer. In such a complex terrain, once it falls into darkness, it will be very dangerous.

It was terrible. So Bai Chi quickly followed Bai Ping and ran out.

After running among the pile of pipes for several minutes, Bai Ping shouted as soon as he stopped: "There is a fork in the road!"

Bai Chi looked up and saw two iron doors at the end, but they were both opened. After looking, he found a stairwell for an emergency escape route, and the other was a winch-type elevator. Unexpectedly, there was such a thing underground in the ancient tomb.

Advanced facilities.

At this time, the generator stopped running, and of course I ran into the emergency exit, but I didn't know whether it was up or down. This is a very serious problem. Once you make the wrong choice, you will be surrounded by poisonous gas, and sooner or later you will die.

.

Based on the amount of poisonous gas we saw before, it will spread here in less than two minutes. Bai Chi coughed and said immediately: "Go up!"

"Up?" Bai Ping looked back. The lights outside had been extinguished, and he couldn't see the scope of the spread of the poisonous gas. Before Bai Chi could speak, Bai Ping grinned again and said:

"Clan leader, I'll go ahead!"

Because we don’t know the density of this gas or the building structure here, but from what we have seen before, poisonous gas pipelines extend in all directions, and we have no idea where the storage room or manufacturing site is.

If you go below, you can save your life. If you choose wrongly, you will face the danger of being surrounded by poisonous gas in the emergency passage.

At this time, Bai Chi was sweating and felt very uneasy. He didn't know whether his guess was right or not. If he was wrong, then rushing forward would be like rushing to reincarnate.

I really don’t know much about the little devil’s poison gas storage room, but I know that the water flow generator needs the power of the drop generated by the river to drive it. Baichi is betting on the possibility that the little devil will put all the important facilities underneath, and it must be very deep, otherwise the sound of the generator will

It will be huge.

The four of them kept climbing up the stairs. They didn't feel tired at all. They didn't know how many floors they had climbed. When Bai Chi was about to faint, Bai Ping suddenly stopped. Bai Chi quickly looked up, and he was covered in cold sweat.

Bai Ping grabbed a handful of dirt from the ground and cursed: "The top was blown up!"

Cheng Hao and Liu Wei, who were following closely behind, raised their heads and looked up.
