In the confined underground space world, Yuan Feng's mind patiently exploring the surrounding cave walls. From being cautious at first to being let go of the power later, Yuan Feng was obviously really anxious, but the intensity of the investigation was constantly 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 into the hall by the Blood Demon Ancestor, it would be his turn in the end.

Regardless of whether it takes a lot of time or not, the result must be certain. Therefore, he must not be lucky enough to find a way out as soon as possible and find a way to leave here before it is his turn.

After a long search, Yuan Feng searched almost every inch of the hole wall around him. Unfortunately, the final result was really unsatisfactory.

"How could this happen? It turned out to be a confined space? Are you going to kill me?"

With a low expression, Yuan Feng's heart was filled with coldness at this moment.

Judging from his investigation, although the current space world is not a different dimension space opened by the Blood Demon Ancestor, it is also a closed world opened by the other party underground. It is obviously not that easy to escape from this underground world.

There is no portal space, except for the powerful people in the Cave Heaven Realm who can move out directly, the warriors in the Cave Heaven Realm can only break open the cave wall and escape. Unfortunately, this underground space is probably in a very deep underground. The surrounding cave walls are known how thick they are. If they want to break open, the movement will definitely not be small.

How alert is the powerful man in the Cave Heaven Realm? If he digs a hole wall outside, he will probably be noticed by the other party immediately. The Blood Demon Ancestor who hears the movement will not be able to catch him in appearance? In such a confined space, he will have no way to heaven and no way to enter the earth, and he will have to be slaughtered by others.

"It's so troublesome. Why do you have to choose such a place?"

After retracting his mind, a trace of bitterness flashed in Yuan Feng's eyes. Now, if you want to break through the surrounding hole walls and escape, this method can be almost ignored.

"This is such an empty space, not even a hidden place. What should I do?"

Even if he was calm, Yuan Feng felt a little worried at this moment. He couldn't escape and had nowhere to hide. Judging from the current situation, it seemed that there was only a dead end!

"Is that true, did you really use up all your good luck? But there is no need to be so thorough, right?"

He sighed in his heart. At this moment, Yuan Feng really had the urge to curse. He had always had good luck, but this time he came to the Moluo Realm, he would encounter such a depressed situation.

The Moluo Realm is so big that it is so great that the six-star master actually left him there. If he changed his place, there would be no such passive situation now.

Also, if he could leave the previous Moro gathering area one day or half a day earlier, he could have avoided this disaster. Unfortunately, if there were many, but there was only one fact!

"brush!!!"

While speaking, the Blood Demon Ancestor appeared again. The ordinary warrior who had caught a handful of them returned directly to the palace. This time, the ancestor was obviously even more anxious. He was afraid that he would not have even less than half a second to appear. In other words, people with cultivation like Yuan Feng could see clearly. As for those ordinary people in the innate realm and the Killing Realm, they could almost only see a vague shadow flashing by.

"It's almost half an hour apart, right? It seems that what this guy is doing seems to take longer than it takes!!"

Seeing that the Blood Demon Ancestor hurriedly caught the person and disappeared, Yuan Feng couldn't help but move his mind and narrowed his eyes slightly.

He didn't know what the Blood Demon Ancestor did in the hall, but he could see that the more he did, the longer the time it took, the longer it took. The time interval this time was obviously half an hour.

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

After his thoughts moved, Yuan Feng suddenly had some thoughts at this moment.

Now that he has nowhere to escape, nowhere to hide, it seems that he has no other choice.

"It seems that I can only fight with this guy. Before it's my turn, I can prepare carefully. Maybe there will be a glimmer of hope."

Since you can't escape or hide, you can only fight with the other party. Although this idea is a bit crazy, it's better than just waiting to die.

The most important thing is that the Blood Demon Ancestor is obviously concentrating on doing some things in the palace, and has not investigated the outside world so far. With the Tianshen Wu Ling in his body, he has absolutely the right to speak for it.

Thinking about it, the Blood Demon Ancestor used the power of the cave heaven to lock everyone out. Of course, he would not worry about any abnormal movements of these people. If he had to be careful about these ordinary people in the innate realm and the Killing Dan realm, he would not be a super strong man in the third level of the cave heaven realm.

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

I didn't dare to think about it before, but now I start thinking about it, Yuan Feng realized that judging from the current situation, he really has a lot of articles to do. At least, he definitely doesn't need to stand here and wait for death.

"What, what can I do with 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!!"

With a sudden gritted teeth, Yuan Feng had a final decision in his heart.

"From my current situation, the only one who can deal with the powerful people in the Cave Heaven Realm is the Nine-Curve Yellow River Formation. If the Nine-Curve Yellow River Formation can be arranged here, I will be the main formation at that time, and then supplemented by the power of the Chixiao Sword, I may be able to deal with the opponent, even kill the opponent to the greatest extent, and find a chance to escape."

With his eyes slightly brighter, Yuan Feng's thoughts turned quickly, thinking about all possible actions and possible results.

Obviously, the Xuan Formation must be the only way to deal with the Blood Demon Ancestor in the Cave Heaven Realm. Although he has not felt the power of the Jiuqu Yellow River Array, he believes that with his formation methods and the reputation of the Jiuqu Yellow River Array, he should be able to at least compete with the Blood Demon Ancestor.

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

The only problem at the moment is how to arrange the Nine-Curve Yellow River Formation. Although the Blood Demon Ancestor will not come out for a while, during the formation process, he is really worried about what he makes. If he accidentally makes movement, he will be torn to pieces by the other party before the formation is completed.

"You have to take this risk. If you are discovered, you can only think of yourself as unlucky. Then you will find another way to survive. In short, you must compete with the other party this time."

No matter what, setting up the Nine-Curve Yellow River Formation and dealing with the other party was the only way he could think of. Since that is the case, what should he hesitate?

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

With a sudden fist, Yuan Feng stopped hesitating. While converging all his breath, he moved his true energy and directly created a barrier of true energy around his body. With this layer of true energy barrier, it was difficult for these ordinary warriors present to discover his actions, and they could also prevent too much movement during action.

"brush!!"

With a moving body, Yuan Feng's body suddenly disappeared from the spot. When it appeared again, it had already reached the bottom of the cave wall of this underground world.

Since we are going to arrange the Nine-Curve Yellow River Array, it is arranged large enough. I think it should be really not small to include the entire underground space!

"kindness?"

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

Yuan Feng was located at the edge of the side, and there was only one person on one side. Now he suddenly disappeared, and the people around him were naturally the first to discover the problem. However, although this guy with the Great Perfect Kalpa Realm was surprised, he could not make any sound, and he could not share this information with others.

Of course, Yuan Feng didn't have the heart to consider the other people's ideas. At this moment, he had already arrived under the cave wall. As the true energy moved, crystal stones were taken out one by one by one by one by one by one and carefully arranged them under the cave wall.

These crystals were treasures he had obtained in Wanren Mountain in the Dharma Realm. The energy of each crystal was stronger than that of the Star Crystal. He usually couldn't bear to use them. Now that he wanted to deal with the powerful people in the Cave Heaven Realm, these crystals were really useful.

The body moved lightly, and even a trace of air would not drive. At this moment, Yuan Feng could be said to have been careful that he had never been before. Of course, he also prayed that the Blood Demon Ancestor would not suddenly explore the outside. If the other party had a whim and really suddenly investigated the outside, then he would definitely have nowhere to hide.

"God bless you, at least let me arrange the Nine-Curve Yellow River Formation, otherwise I will die with my eyes open!"

He gently placed the crystal stones under the cave wall according to the arrangement method of the Nine-Curve Yellow River Formation. Yuan Feng didn't care whether he would be seen by the people present, and all his thoughts were used on the arrangement.

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

On weekdays, he had already practiced the Jiuqu Yellow River Formation very skilled, and he could arrange it in minutes at the fastest time. However, this time was different from the past. Since he could not make any movement, it obviously took a lot of time to set up the formation this time.

As time passed, Yuan Feng did not dare to be careless at all. Gradually, his forehead became slightly wet.
