After returning to the first floor, Lu An used his strength to imprison all fifty people. Without moving, he directly used his strength to lift up the fifty people and send them into the passage.

The height of the first floor is three thousand feet, and there is a teleportation array three thousand feet underground. Lu An is only ten thousand feet away from Lu An standing on the ground. Lu An controlled fifty people and sent them to the passage three thousand feet underground. He opened the teleportation array ten thousand feet away.

Push all fifty people into it.

Then, Lu An opened the teleportation circle again and returned to the fourth floor.

Lu An continued to search the land without blood mist, but unfortunately, except for the fifty people just now, there were no more people in this open space. After completely searching the open space, Lu An set off again and rushed into the blood mist.

In the fog, he headed towards the due north. What he had to do was to rush out of the blood fog and enter the next clearing.

After finding Yu Yan, he did not need to go all out in his actions like before. Instead, he chose to slow down slightly, absorb the power of death around him, and move forward at a constant speed, maintaining a balance between consumption and absorption, so that the power in his body could be maintained.

It always remains above 80%. Although even if he is weaker, he will not be a threat at the fourth level, Lu An has always been a cautious person, and the most common state of caution is to ensure that he has sufficient strength.

Rushing in from the edge of the blood mist, I felt that the intensity of the power of death gradually increased, rapidly changing from level six to level seven, and then to level eight. Lu An's brows were slightly condensed while flying, and he was scattered.

I keep thinking while opening my perception.

He was still thinking about the previous question, why was there such a huge power of death underground? The fourth level was so serious that most of the area was swallowed up, so how powerful was the fifth underground level?

And now he is thinking more. Since Fu Yu came to inform him, it is enough to show that the Bagu clan is very aware of the situation in the underground world, but it seems that they are not prepared to take action to manage it, otherwise they would not let him take action. This death

The power seems to spread continuously, and if this continues, the entire underground world may be swallowed up in less than ten years. By then, can the underground world really wrap up the power of death and prevent it from spreading to the ground?

Or... the Bagu clan will take care of it, but it's just that the front line is busy with wars and they can't spare a hand, so they let themselves rescue people first and wait for them to deal with it later?

There were too many possibilities, and he knew too little. Lu An took a deep breath and allowed himself to

Don’t think too much. With your current strength, you are not qualified to know more things. It is better to do what you should do first and not to aim too high.

——————

In the next ten days, except for returning home twice to report that he was safe, Lu An spent all the time on the fourth floor.

When returning home to report the safety, Liu Yi said that Zhu He had arranged for all the rescued people and integrated them into the organization according to the standards of the Heavenly Alliance. The rescued people were all seventh-level and eighth-level experts.

Super powerful people have strong self-discipline and are not difficult to manage. Moreover, these people were completely shocked after learning the news about the real world. Their worldview was completely overturned. When they saw the sky, mountains and rivers, they were all shocked.

I am glad that I can learn the truth in my lifetime.

These people are very grateful to Lu An and the Celestial People's Alliance and are more willing to be loyal to them. The people of the Celestial People's Alliance have many topics to talk about with these people, such as Qi and combat skills. Celestial People's

People in the alliance were also curious about what the underground world was like, but after hearing the descriptions of these rescued people, although they were curious, they had no yearning.

The person who asked Liu Yi to mention more was Yu Yan. Zhu He made Yu Yan the leader of the seven-level strong men and seemed to be particularly concerned about her. Lu An was a little confused after hearing this. Although Zhu He was not young, he still had a few years left.

A life span of hundreds of years. More importantly, among Celestial Masters, because they can change the body through power and always keep the body in a young state, and the life span is too long, many secular moral standards do not exist among Celestial Masters.

Applicable. Lu An doesn’t know if Zhu He has ever had a wife, but he is indeed alone now. Could it be that...

However, Liu Yi also said that Zhu He was just more caring and did not have any deviant behavior. This was especially true for Yu Yan. The two of them did not have much interaction. Lu An nodded slightly after hearing this. This is other people's feelings, so naturally he does not

will care about these things.

With Lu An's current strength, he can fly far and wide in ten days. Even Lu An himself doesn't know how far he has flown, but he can remember the route he took. Otherwise, if he can't remember the route,

line, it is likely to search for a location repeatedly.

Just like the intelligence, there are mostly blood mist on the fourth floor, and there are only a few open spaces. Based on ten days of observation, the blood mist accounts for 80% or even higher, while the open spaces are only slightly more than 10%. In ten days, Inland Security only found four batches.

People, as well as a group of lives gathered together to escape, are enough to illustrate the death situation on the fourth level.

This kind of casualties is not much better than that of humans in the above world.

More than 90% of the four groups of people were willing to leave, and only a handful of people were unwilling to leave. Naturally, Lu An would not force him. Lu An did not know whether to save the fleeing life. After repeated thinking and discussions with his family, Lu An decided

It was decided to send them to the first level of life but not leave with them.

Although this cannot solve the essential problem, it can at least give them a few more years of life. Maybe the problem will be solved within a few years, so that they can save their lives.

In the past ten days, Lu An also saw many people and lives in the blood mist that were swallowed by the power of death, but were not yet dead. These people and lives were wandering and going crazy in the blood mist, and in fact they had completely lost their lives.

Personality and even the origin of spiritual consciousness were invaded and swallowed by the power of death and turned into blood. They completely lost themselves and there was no possibility of saving them. These people would not have wanted to be like this before they were swallowed, so Lu An took action.

Choose to kill these lives.

One is to let these people die with dignity, and the other is to prevent these lives from breaking out of the blood mist and hindering the fleeing lives.

He spent most of the ten days on the road. In fact, such a journey did not mean much to Lu An. Although the power of death around him was strong, the strongest he came into contact with was only the peak level eight intensity. And

Even at level nine strength, the pure power of death doesn't mean much to Lu An.

The purpose of coming here is to save people, but if he wants to search the entire fourth floor, even Lu An will have to spend an unimaginable time, which is definitely not acceptable to him. He can only try to save people,

After a while, he will probably give up here, stop searching, and return to practice above.

In fact, he had thought about this matter more than once in the past ten days. If he had gone to the underground world by himself, he would have left. The reason why he did not leave was precisely because this was Fu Yu's request.

.

This was also the point that puzzled him the most. Why did Fu Yu want him to come here?

Fu Yu has always asked himself to practice hard and become a strong person as soon as possible, but with Fu Yu's wisdom and intelligence, he must know the situation on the fourth level, and he also knows that there is no benefit to his cultivation here, so why should he come?

To save people?

This is indeed a reason, but in Lu An's view, this reason is far from enough. If this was the only reason, Fu Yu would never let him come.

If it's not to save people, then why?

Lu An was thinking while flying. After about an hour, he finally rushed out of the blood mist again. But unlike the open space he encountered before, this open space was not large. Lu An successfully found a group of people here.

The person, saying the same words as he did several times before, sends away those who are willing to leave with him.

After seeing him off, Lu An continued on his way on the fourth floor. Keeping heading north, he quickly rushed into the blood mist again, flying at high speed in the blood mist.

Level six strength...level seven strength...level eight strength.

As before, the intensity of the power of death gradually increases from the edge to the depth. So far, Lu An has not found a passage to the fifth floor, which is enough to show that this passage is very rare, far more than the third to fourth floors.

Much less.

After flying in the blood mist for three full hours, not only did he not fly out, but he was still in the eighth-level death power, which is enough to show how huge this blood mist is. Lu An was feeling and thinking about cultivation issues while flying.

, at least this way he won't get nothing.

However...a sudden change occurred!

Just after Lu An flew for another moment, his body suddenly shook, and his figure immediately stopped and froze in place!

At the same time, his eyes obviously became very serious and dignified, looking towards the north!

"Roar!!!!"

There was a roaring sound, billowing from the thick blood mist ahead! And accompanying the roaring sound was a terrifying aura!

Lu An's fists were gradually clenched, and all the power in his body was fully mobilized!

Level nine aura!
Chapter completed!
