The people were just shouting in surprise, and then shut up immediately, as if some monster here would suddenly jump out and eat them.

Then, they carefully carried the corpses on the ground out, walking faster and faster, as if there were devils chasing them behind them.

"Is it so exaggerated?"

Han Yu smiled whispered. Looking around, there was a lot of space here, probably the size of a few basketball courts, and there were some piles of stones like hills around.

There seems to be nothing scary?

The more this happened, the more puzzled Han Yu was. Thinking of the performance of the group of people just now, it was definitely not ordinary here.

The supervisor wore black clothes, wearing black towels, covering his whole body. In this dark environment, he could not see his appearance clearly.

One of them spoke.

"The first time you have entered a hole, I'll tell you the rules. First of all, the most important thing is that you must not reveal a single trace of it after you go out. If you dare to violate it, you will be killed without mercy!"

"At this moment, all of you are in a group. If anyone leaks this group, everyone must die!"

"So you all have to supervise each other!"

The voices covered by the supervisor's black clothes were a little vicissitudes. Han Yu couldn't find out the other party's cultivation level. This situation only shows that the other party is definitely a cultivator in the Earth Immortal Realm.

Qingfeng Mountain said that there are only three kings who are earth immortals, but who knows how many hidden it is?

"Many people who come in for the first time probably have a lot of confusion. Why are they scared of this? What's the trick here?"

The black-clothed supervisor finally reached the point.

Han Yu concentrates on it.

"Due to the particularity of black iron stone, only a small part of the place can arrange defensive formations, but after mining here, the stone walls above become loose, falling from time to time, and sometimes even large-scale collapses. So you must be vigilant at all times. Once you find something wrong, hurry up and retreat to the defensive formation. If it is slow, I can't help it!"

This statement has solved Han Yu’s doubts over the past two days, ‘So that’s what happened. No wonder those people are afraid of this place. Coming here is like a pack of explosives on their heads working. No one knows when the stone on their heads will fall?

When Han Yu heard that the danger inside was like this, he secretly breathed a sigh of relief. When his cultivation level was not as good as that of now, he broke through the Overturned Universe Formation. The falling giant stone was not comparable here...

The black-clothed supervisor told a lot of rules, and then he asked Han Yu and others to start doing things.

The things they do are not complicated, just use the iron rod and hammer in their hands to knock the black iron stones in the designated parts into pieces.

What is needed is brute force, no technology.

Everything looks calm for the time being.

...

Xiahou Jin was thinking about how to repay Han Yu's kindness. According to the previous rules, Han Yu and the others would not enter the cave after three days, so these three days are safe.

"In three days, what reason should I find to prevent them from entering the hole?"

Just as Xiahou Jin was racking his brains, someone suddenly sent an order to send him a batch of black iron stones to Taoism the day after tomorrow.

After taking the order, Xiahou Jin immediately slapped his thigh, "Well, let the three of them accompany me to deliver goods, so there is no need to do work!"

Every time he sent a lot of black iron stones to Taoism, he definitely couldn't do it alone and needed other people's help. Since Xiahou Jin stayed on this Qingfeng for a long enough time, he was somewhat embarrassed. He wanted to designate someone to send him off, which was OK!

Xiahou Jin was thinking about it, but he didn't know that Han Yu and others had already entered the cave.

And I've been working for a while...

Han Yu held an iron rod and knocked on it. The iron rod was about half a meter, and one end was very sharp. The iron rod with the left hand and the hammer with the right hand was ding ding dong.

Suddenly, there was a thud.

A stone suddenly landed above his head, like a time bomb, and accurately greeted Han Yu's head.

If others encounter this, they will definitely be either dead or injured, but Han Yu waved his hand gently and cleverly split the stone.

Dongdong, the two stones were divided into two halves and fell on Han Yu's side.

“Great luck!”

When the rest of the people saw Han Yu's actions, they said ventricularly that in this case, it is difficult for ordinary people to react.

But they did not show any surprise expression. Some workers who had entered holes before had seen better luck than Han Yu, but good luck was just a moment, and what they really depended on doing things here was reaction.

You must have a sensitive insight, run away quickly when the danger comes from, and hide in the defensive formation is the best strategy.

In fact, the stone like the one that just fell on Han Yu's head was just the smallest one.

There are even more dangerous things to come...

People who have entered the hole have experience, so the position of the station is very particular. No matter how you move, you must ensure that you are closest to the defensive formation.

Wang Zhanlong is an experienced person, and Han Yu naturally knew him. Seeing this, he said, "I am just a newcomer. I'm lucky enough to hide from a stone. I will definitely die soon!"

Han Yu's action was just a small episode. Although it also made many people's eyes shine, it would not achieve amazing results in the end...

I wonder what everyone was thinking, Han Yu was very calm. He secretly used the light of Taihu Lake to calculate the structure of the cave to see if he could find a way to solve the problem of falling stones?

But now it seems to be a bit troublesome, unless it is poured with concrete, so that it can be safe.

But is there cement in this world?

Just as Han Yu secretly considered the feasibility of this plan, a sudden roar of roar was heard.

"It's a landslide, run away!"

The experienced person yelled, and before Han Yu could turn sideways, he saw a large pile of stones falling down behind him.

This is not smaller than the one just now. It falls down and then burys the person directly.

Wang Zhanlong and a small number of people seemed to have springs installed on their legs. The moment they collapsed, they came to the defensive formation.

He patted his chest hard, "I'm so scared, but fortunately I escaped another disaster!"

This kind of large-scale landslide is safe only if it quickly runs into the defensive formation.

However, the area where you can arrange defensive formations is limited, so when you encounter a landslide, it means that at least a part of the people will die.

This is the cruelest thing in the cave, just like playing the death game. It was still alive in the last second, but was buried by a pile of stones in the next second. If you can live for two days and one night, you will be disabled even if you are not crazy.

"Oh, it's a pity that the three newcomers died just one day after they came in. They wanted to blackmail more meat and add some food, but now it seems that they are not good!"

Wang Zhanlong muttered at the pile of stones in the distance.

Han Yu and the other three had really bad luck this time. The landslide was above their heads, and the people around them reacted quickly. Some ran into the defensive formation, and some happened to avoid it, and just buried the three of them.

"Oh, this is fate!"

Some people sighed that Han Yu was lucky enough to escape a small stone, but he did not escape the pile of stones.

If at least ten square meters of stones fall like this, ordinary people will definitely die. Only the earth immortals have the opportunity to support the energy shield and escape.

...

Under the pile of stones, Han Yu supported a huge rock alone and protected Saga and Zhang Bairen under him.
