In the sealed underground space world, Yuan Feng's mind was patiently exploring the surrounding cave walls. From being cautious at first to letting go and taking action later, Yuan Feng was obviously really anxious. The intensity of his exploration,

But it keeps increasing.

Although it seemed that there was no danger at the moment, he knew very well that after everyone in front of him was captured by the Blood Demon Ancestor and taken into the hall, it would eventually be his turn.

No matter whether it takes a lot of time or not, the result is bound to be certain. Therefore, he must not take any chances. He must find a way out as soon as possible and find a way to get out of here before it is his turn.

After probing for a long time, Yuan Feng explored almost every inch of the cave wall around him. Unfortunately, the final result was really unsatisfactory.

"How could this happen? It's actually a confined space? Are you trying to kill me?"

Yuan Feng's face was gloomy. At this moment, Yuan Feng's heart was filled with coldness.

Judging from his investigation, although the current space world is not a different-dimensional space opened up by the ancestor of the Blood Demon, it is also a closed world opened up underground by the other party. He wants to silently escape from this underground world.

Escape is obviously not that easy.

In a space without a portal, except for the strong ones in the Cave Heaven Realm who can move out directly, the warriors under the Cave Heaven Realm can only break open the cave wall and escape. Unfortunately, this underground space is probably in an extremely dangerous state.

It's extremely deep underground, and the surrounding cave walls are God knows how thick. If you want to break them open, there will definitely be no small movement.

How vigilant is a strong man in the Cave Heaven Realm? If he digs a cave wall outside, he will probably be discovered by the opponent immediately. When the Blood Demon Ancestor hears the noise, he will not be able to catch him and reveal himself? And in such a confined space

, he will simply have no way to go to heaven and no way to enter the earth, and he will have no choice but to be slaughtered by others.

"You're in big trouble. Why did this damn old guy have to choose a place like this?"

With his mind back, Yuan Feng couldn't help but a trace of bitterness flashed through his eyes. Now, if he wanted to break through the surrounding cave walls and escape, such a method could almost be ignored.

"In such an empty space, there is not even a place to hide. What do you want me to do?"

No matter how calm he was, Yuan Feng felt a little worried at this moment. He couldn't escape, and he had nowhere to hide. Judging from the current situation, it seemed that there was only one way to die!

"Yes, have you really used up all your good luck? But there's no need to be so thorough, right?"

I sighed in my heart. At this moment, Yuan Feng really had the urge to curse his mother. His luck has always been good, but this time after coming to the Demon World, he encountered such a depressing situation.

The Moluo Realm is so big and so undead, that Six-Star Lord actually left him there. If he had been in another place, he wouldn't be in this passive situation now.

Also, if he could have left the previous Moro gathering area a day and a half earlier, or even an hour earlier, he would have been able to avoid this disaster. Unfortunately, there are many, but there is only one fact!

"brush!!!"

While he was talking, the Blood Demon Ancestor appeared again, grabbed a handful of ordinary warriors, and returned directly to the palace. But this time, the Ancestor was obviously more anxious. The time he appeared was

, I’m afraid it won’t even last half a second. That is to say, people with cultivation levels like Yuan Feng can see clearly. As for those ordinary people in the Xiantian and Danjie realms, they can almost only see a blur.

The shadow flashed.

"It's been almost half an hour, right? It seems like what this guy is doing seems to take longer and longer each time!!"

Seeing the Blood Demon Ancestor hurriedly arresting people and then disappearing, Yuan Feng couldn't help but think, and narrowed his eyes slightly.

He didn't know what the Blood Demon Ancestor was doing in the hall, but he could tell that the further back what the other party did, the longer it would take. This time, the time interval had obviously reached half an hour.

.

"Half an hour seems to be enough for me to do a lot of things!"

As his mind moved, Yuan Feng suddenly had some ideas at this moment.

With nowhere to run and nowhere to hide, it seemed like he had no other choice.

"It seems that I can only fight with this guy. Before it's my turn, I can make serious preparations. Maybe I can still have a chance of survival."

Since there is no way to escape or hide, the only option is to fight with the opponent. Although this idea is a bit crazy, it is better than sitting back and waiting for death.

The most important thing is that the Blood Demon Ancestor is obviously concentrating on doing something in the palace, and the outside world has not been investigated so far. On this point, he has the absolute say with the Sky-Devouring Martial Spirit.

Thinking about it, the Blood Demon Ancestor used the power of the cave to lock everyone out. Of course, he would not worry about these people doing anything strange. If he were to deal with these ordinary people in the Xiantian Realm and the Core Formation Realm, he would be careful to guard against them.

If so, then he is no longer a super strong person in the third level of the Cave Heaven Realm.

"It was half an hour last time, so the next time he shows up, it should be at least half an hour. A full half hour is enough for me to do a lot of things."

I didn't dare to think about it before, but now that I started to think about it, Yuan Feng realized that judging from the current situation, he really has a lot to do. At least, he definitely doesn't need to stand here waiting to die.

Already.

"No, what can happen to the third level of the Cave Heaven Realm? I want to see if he, a guy from the third level of the Cave Heaven Realm, can really be immortal!!"

Gritting his teeth suddenly, Yuan Feng had already made a final decision in his heart.

"Judging from my current situation, the only one that can deal with the powerful ones in the Cave Heaven Realm is the Nine-Bend Yellow River Formation. If the Nine-Bend Yellow River Formation can be set up here, I will be the main one, supplemented by the Chi

With the power of Xiaojian, it may be possible to deal with the opponent, even kill the opponent to the maximum extent, and find a chance to escape."

With his eyes slightly bright, Yuan Feng's thoughts were spinning rapidly, thinking about all possible actions and possible results.

Obviously, if you want to deal with the Blood Demon Ancestor in the Cave Heaven Realm right now, the Mysterious Formation must be the only way. Although he has not yet felt the power of the Jiuqu Yellow River Formation, he believes that with his formation method, plus the Jiuqu Formation

The reputation of the Yellow River Formation should at least be able to compete with that of the Blood Demon Ancestor for a while.

Not to mention anything else, as long as the Blood Demon Ancestor can be trapped for a while, he can then let Xiaoba dig a hole in the cave wall and try to escape from this underground space.

The only problem right now is how to set up the Nine-Meandering Yellow River Formation. Although the Blood Demon Ancestor will not come out for a while, during the process of setting up the formation, he is really worried that he will make some noise. If he is not careful,

If he makes any noise, he will be torn into pieces by the opponent before the formation is formed.

"You have to take this risk. If you are discovered, you will have to admit that you are unlucky. Then you will find other ways to survive. In short, you must fight with the opponent this time."

In any case, setting up the Nine-Meander Yellow River Formation and dealing with the opponent was the only way he could think of. And in this case, why should he hesitate?

"If you do it, whether you live or die, it all depends on this time!"

With a sudden clenched fist, Yuan Feng no longer hesitated. While gathering all the breath in his body, he moved his true energy and directly created a layer of true energy barrier around himself. With this layer of true energy barrier,

, but it is difficult for the ordinary warriors present to detect his actions, and it can also prevent him from making too much noise during his actions.

"brush!!"

With a movement of his body, Yuan Feng's body suddenly disappeared from the spot. When he reappeared, he had already reached the bottom of the cave wall in this underground world.

Since we are going to set up the Jiuqu Yellow River Formation, we need to make it large enough to include the entire underground space. It should be really big!

"kindness?"

When Yuan Feng's figure disappeared from the spot, the other six people in the last row who were placed there with him, the guy next to him, suddenly shrank his pupils.

Yuan Feng's position was on the side, and there were only people on one side. At this moment, he suddenly disappeared, and the people around him were naturally the first to notice the problem. However, although this guy who was in the Great Perfection of the Dan Formation Realm was surprised

, but it couldn’t make any sound, and it couldn’t share this information with others.

Of course, Yuan Feng had no intention of considering other people's thoughts. At this moment, he had already arrived under the cave wall. With a movement of his energy, he took out crystal stones one after another and carefully arranged them.

Under the cave wall.

These crystals were all treasures he had obtained in the Wanren Mountain in the Dharma Realm. Each crystal had stronger energy than the star crystal. Normally he would be reluctant to use it, but now he wanted to deal with the strong men in the Cave Heaven Realm.

These crystals can be considered to be really useful.

His figure moved lightly without even a trace of air. At this moment, Yuan Feng could be said to be more cautious than ever before. Of course, he also prayed that the Blood Demon Ancestor would not suddenly explore the outside.

, if the other party really suddenly explores the outside on a whim, then he must have nothing to hide.

"God bless me, at least let me lay out the Nine-Meading Yellow River Formation, otherwise, I will die with my eyes closed!"

Gently placing the pieces of crystal stone under the cave wall according to the formation method of the Jiuqu Yellow River Formation, Yuan Feng didn't care whether he would be seen by the people present, all his thoughts were spent on it.

Arrange on top of the array.

Anyway, these guys here can't move or speak, so what if they see you?

On weekdays, he has already practiced the Jiuqu Yellow River Formation very skillfully. At the fastest time, he can complete the arrangement in minutes. However, this time is different from the past. Since he can't make the slightest movement, the formation this time can be completed.

It obviously takes a lot of time.
Chapter completed!
