Old Mrs. Huo was well prepared for this action. Not only did she bring all kinds of equipment, but she also prepared strong acid sprays specially used to melt rocks and chemical protection suits.

It is a strong acid sprayed with an air-pressure spray can. When sprayed on the rock, it can quickly melt the rock. The gaps hidden in the mountain will soon be revealed, which is more than ten times faster than manual excavation.

Everyone was already exhausted when they ran all the way, so they rested by the lake for three days because they had to wait for Wu Xie to get the result before they could go deep into the Zhang family ancient building.

The Zhang family ancient building has a deep connection with the ancient tombs on the Siguniang Mountain, and many places can be compared as reference objects.

They have established a complete communication system to facilitate the delivery of messages from both parties to each other as soon as possible.

This was impossible to achieve in ancient times, so the ancients did not expect that modern high-tech equipment could easily crack the various mechanisms they carefully designed back then.

As the orthodox Faqiu Tianguan, Chen Hao naturally became the leader of this team, and no one had any objections to this.

Because no one here can compare with Chen Hao in terms of experience or ability. He once led the team deep into the Yunding Heavenly Palace and the desert Gobi, and was an expert in ancient tomb exploration.

Although Man Youping is also very good at communicating with others, he is not good at communicating with others. If he is asked to lead the team, there are some things that are difficult to communicate when he acts.

After the team rested by the lake for two days, Wu Xie finally set off and arrived at the ancient cave on the cliff of Siguniang Mountain, and sent them some pictures and information.

Wu Xie's progress was very smooth because Chen Hao taught him many methods to use his own blood to open the way, easily avoiding the mycelium that looked like hair, and without touching the jars, he easily arrived at the iron plate that looked like a "cymbal".

Seeing that Xiaohua and the others had gained something, Chen Hao also brought the team to the outside of the gap in the mountain where they escaped last time.

However, the previous gap has completely healed, forming a complete mountain, which makes people wonder where to start.

"This ghost place is really weird. There was a passage last time when I came out, but now it has healed. This fucking thing is completely beyond the scope of physical laws." The fat man muttered.

The last time the three of them were trapped in that strange cave, they could not find the exit. They had a deep understanding of the weirdness here.

"This place cannot be explained by common sense. You can wait for me and I will find the exit!" Chen Hao said.

After saying that, he walked straight to the gap he left last time. Although there was already a rock, he knew that the gap was hidden in these rocks. But for some reason, he backfilled the gap again.

Chen Hao stretched out his hair and strode the rocks for a while and found that although the rocks looked exactly the same, their textures were still different when they felt. Some places obviously had a kind of jade-like softness, while others were exactly the same as stones.

Everyone stood by and looked at him, and no one dared to disturb him.

After searching for a while, Chen Hao used his fingers to draw a rough outline on the rock, and then said to the people wearing chemical protection suits:

"Just spray strong acid within the range marked by me."

The people wearing chemical protective suits nodded when they heard this, then raised their watering can and came to the rocks, and everyone retreated one after another.

Then the two men began to squeeze the watering can, and an object like mist sprayed out of the watering can and sprayed onto the wall.

A strange scene appeared. As soon as the strong acid spray touched the divided rocks, the rocks immediately began to melt like liquid.

After a large number of rocks melted like liquid, they fell to the ground, gradually highlighting a gap hidden in the mountain.

Seeing that there was enough strong acid spray on it, Chen Hao quickly waved his hand to stop them, because they didn't bring much strong acid and had to save some use.

After seeing Chen Hao's gesture, the two guys quickly stopped the jet and retreated to the side. The rock was still melting, and soon a gap appeared, just enough to accommodate a person passing through the mountain.

When everyone saw Chen Hao find a channel in such a short time, they all looked at him with admiration.

The fat man said proudly: "How about the old lady? Now I know that our brothers are not good at bragging about their skills, right?"

Before coming, the fat man was very unhappy with the tests of Mrs. Huo and Xiaohua. He always felt that they underestimated the strength of the four-person group of tomb robbers. Now Chen Hao showed his skills in front of Mrs. Huo, so the fat man naturally wanted to find an opportunity to slapped Mrs. Huo's spirit.

The old woman ignored him, but looked at Chen Hao with a strange look and said nothing.

Chen Hao said to everyone: "Find some solid support to spread the hole open, otherwise it will automatically backfilling after a while."

After hearing Chen Hao's words, some old lady Huo's friends did not dare to be negligent. They quickly took out some solid support from the equipment and supported it on the entrance of the hole, so as not to be blocked from their way back.

After doing this, Chen Hao personally led the team to lead the way forward and walked through the mountain along the gap.

The last time he took Fatty and the others to escape, he found that there were many passages in the mountain, but at that time he was just escaping and had no time to explore where these passages lead.

Now their purpose is to find the Zhang family ancient building, so they asked someone to draw these passages and clarify the terrain in their bodies.

There is naturally no shortage of professional drawing masters in the team. They can accurately depict the terrain in the mountain in a very short time.

Chen Hao led the team and walked forward for a kilometer along the gap. Three or four passages appeared in front of him. The size of several passages was about the same, but I just didn't know where they led.

"Damn, this is like a mother's maze, what should we do? Macho, which path should we take?" the fat man asked, looking at the passages.

Chen Hao shook his head and said she didn't know either. After all, the passages here were corroded by Milotuo. Who knows where they lead?

However, at this time he had to make a choice. He wanted to use the method of listening to sound to determine whether these channels were feasible. At least find one that could be passed, otherwise it would take more time to find each one.

He broke off a few rocks and threw them into the depths of several passages. Then his ears kept shaking. He listened carefully to the sound coming from the passage, and soon there was a result.

He chose a passage without echoes and brought everyone into it.
