Ouyang Chao's main force actually didn't bring many people, just dozens of people.

They were not with the rest of the disciples of Haotianmen, and these dozens of people were the core force that Haotianmen had cultivated for this trip to the Immortal Cave Mansion.

What they do is relatively secret, and it is inconvenient for too many people to know, even if it is some disciples of their own sect.

Because some disciples of their own sect may tell those secrets to other sects.

There's nothing unusual about this.

Because there are some big martial arts families who will let their children defect to multiple sects, although those children are also disciples of the sect, but at the same time they are still members of their own family, and they are closer to their own families by nature.

If this secret will cause their family's interests to suffer, they may make this secret public, so that Haotianmen will become the target of public criticism, and they will be very passive.

Even if this sect itself is very powerful, it is impossible for them to confront the alliance formed by those other sects in this world.

Therefore, this time they acted, there were only these dozens of disciples who had been accepted into the sect from the beginning.

These people have no other entanglements of interests outside the sect, which can guarantee their purity.

After obtaining the Earth Spirit from the underground palace, they went to a place with more treasures.

Of course, all the treasures in that place are not as important as an earth spirit, but they can make a sect more powerful.

There are also some saint-level and even immortal-level exercises and jade slips, which are very important.

However, after they came here, they only put away those exercises and jade slips, and they didn't take any of those magic weapons, but put them in the treasure hall.

They're doing something else here.

Of course, they knew that there were more treasures in this Immortal Cave Mansion, and they also knew where those treasures would cause what kind of competition, and their current strength would be fought for in the past, and of course they could make a lot of profits, but they didn't do it.

They don't feel the need.

Their goal was to wipe out the disciples of other sects who had entered the Immortal Cave Mansion and obtained a large number of treasures.

For them, the strife in the outside world is insignificant, and they don't need to take a look at it squarely.

The existence of these people, Fang Hao was able to clearly sense through the Earth Spirit and the special sense he had established, and he also knew what they were doing.

According to what he learned in the previous life, most of the people who entered this Immortal Cave Mansion died in this Immortal Cave Mansion, and the biggest beneficiary was of course Haotianmen.

There are also a few relatively large beneficiaries, who belong to the more timid sect forces, and they are not the largest sect forces in the original area.

For example, the Xuanming Sect in the north stayed in a hidden place after obtaining the treasure of the Qinglian Palace, and waited until the Immortal Cave Mansion was closed before leaving this place.

Several other sects that have gained something are almost like this, and after they have some gains, they hide, because they feel that their strength is not able to compete with other people, and they have already made good gains, so there is no need to continue.

Therefore, their main force was preserved, and the treasures they harvested also fell into the hands of the sect, and they rose strongly later.

Some other sects with relatively powerful forces did not have the whole army wiped out, and some of the remaining people from each sect came back, but most of the forces that belonged to the core remained in the Immortal Cave Mansion forever.

A big battle broke out in the last few days of the Immortal Cave Mansion, which was related to the Ten Thousand Treasure Hall, the largest treasure hall in the Immortal Cave Mansion.

The Ten Thousand Treasures Hall has the most treasures in this Immortal Cave Mansion, and in the last few days, almost all of them have received such clues, some of them have not gone over, but many more have chosen to go over.

As a result, none of the people in the past, except for the disciples of Haotianmen, came back alive.

What happened inside, people from other sects didn't know.

At that time, everyone suspected that the disciples of Haotianmen had killed all those people, but they thought that Haotianmen did not have that kind of strength.

The main thing is that they don't have that kind of evidence, and when they encounter such a situation, they can only consider themselves unlucky.

However, Fang Hao later captured several core disciples of Haotian Sect and asked some truths about this matter.

That is in that Wanbao Palace, the owner of this Immortal Cave Mansion, Qinglian Immortal Venerable, had already done a good job and laid out a killing array.

This killing array can be opened by a martial artist of the innate realm, but it only needs a martial artist who cultivates the Haotian Gate Technique to be able to open it and command.

The purpose of setting up this killing array in this palace with the most treasures is, of course, to attract all the disciples who have entered this Immortal Cave Mansion, and then use that killing array to kill all of them inside, and complete the last blood sacrifice of this Immortal Cave Mansion to the spirit of the earth.

At the same time, it is also to weaken the power of those sects.

For most sects, it was a catastrophe, so that their disciples and elites were basically lost in this catastrophe.

Although most of the disciples they sent over existed as cannon fodder, those elite disciples, the sect still had high hopes for them.

The loss of those people is the loss of the potential of a sect in the future.

And the main loss is that none of the treasures they obtained were used to strengthen their sect with the Immortal Cave Mansion.

However, there were so many timid sects that did not go out again after they gained something, although they got such clues, but they felt that they did not have the strength to compete with those powerful sects, and they felt that the treasures they had were enough, so they did not choose to go out, and they survived unexpectedly, and after that, they all became powerful sects in their respective regions.

In the original history, the opening of the Immortal Cave Mansion this time can be said to have rewritten the power map of this continent.

It also made the Haotian Sect, which was originally the most powerful sect in this continent, become more powerful, and in the end, the rest of the sects in this continent had to join hands in order to compete with this sect.

Most of the core forces sent by the five major sects in the south of the Mayfly Continent finally died in this battle, and the gains obtained by the disciples of the sect were basically some medicinal materials that were not very valuable in this Immortal Cave Mansion.

It was collected by those disciples with relatively low strength.

Because those disciples were more afraid of death, they hid in time after they had a certain harvest.

Otherwise, it will be the result of the total annihilation.
