As Chu Feng was about to leave the third layer, he looked at the upper end of the passage again, where there were six patterns floating there, and the six patterns were condensed into six fonts: Yin, Yang, Law, Void, Emptiness, and Surprise.

When Chu Feng saw it for the first time, he suspected that this was Chu Zhenqiong's six natal attributes, and then he fought with Chu Zhi, and this guess was basically certain.

Because Chu Zhi's cultivation method contains the two qi of yin and yang, it is very likely that Chu Zhi has not yet cultivated to the other four realms.

This also shows another thing, that is, Chu Zhi got Chu Zhenqiong's true inheritance, and the cultivation method and Chu Zhenqiong came from the same origin.

Unlike the end of Chu, although it is said to be Chu Zhenqiong's second apprentice, the cultivation method is not the same.

Suddenly, Chu Feng's gaze fell on the top of the six patterns, where there was an inconspicuous black hole spinning, which he hadn't noticed just now.

Chu Feng was curious, and released his mind to observe, but in an instant, he quickly withdrew his thoughts, and his face was solemn.

"The black hole exudes a trace of demonic energy, this demonic energy is exactly the same as the extraterritorial demons, could it be that it is the nest of the group of enemies who emit demonic energy?"

Chu Feng suddenly thought of this possibility, if this was really the case, then on the other side of the black hole, it must be a small world, similar to the world of Evil Demon Mountain.

"Great, if I guessed correctly, this palace is the place where Chu Zhenqiong used to hide for that group of enemies, as long as you bring this news back, it is enough to prove that Chu Zhenqiong and that group of enemies have an indisputable cooperation."

Chu Feng showed joy, hurriedly turned around and left, the clues and answers he wanted to find were all obtained, and the most important thing now was to leave the palace, rescue Ling'er, and then return to the evil sect realm to bring the news back.

It is not advisable to stay here for a long time, once his traces are exposed, he will definitely die without a place to be buried.

Chu Feng left the third floor with a nervous mood and quietly sneaked back to the first floor, without attracting the attention of others on the way, and walked out from the palace gate.

"Why did you stay that long?"

The defender questioned coldly and stopped Chu Feng.

"On the way here, because I was attacked by that group of spirit beasts, my companions died, and the space ring also contained their relics, which were mixed with the spirit grass, so it took a while to take out the spirit grass."

Chu Feng explained, this was also the wording he had prepared at the beginning, and with what he said when he entered the palace, people who had no intention would not think too much.

After all, this is Chu Zhenqiong's palace, how can anyone come to find trouble without dying.

"Alright, let's go."

The guardian waved his hand and said impatiently.

Chu Feng nodded, turned around and left the palace, just as he was looking for an opportunity to leave the guard's sight and go around to the back of the palace, suddenly, the entire sky changed from dark to deep as the sky, and all the light disappeared in an instant, making everyone temporarily lose sight.

Then, the surroundings began to gradually brighten, and a very familiar aura fell from the sky, making Chu Feng tremble.

"It's Chu Zhenqiong!"

Chu Feng sensed that it was Chu Zhenqiong's breath, it was him who came back!

Chu Feng didn't think about why Chu Zhenqiong came back to open the formation, and when the surrounding area had not completely restored the light, he burst out at full speed, disappeared in place like a ghost, appeared behind the palace, and hid in the cave through the palace formation.

All the movements, Chu Feng only took two breaths to complete, the depths of the canyon behind the golden palace was where Ling'er was, before he entered the palace, he had already calculated the steps in his heart, so it was smooth to do it.

The guardian of the palace found that Chu Feng had disappeared when he opened his eyes, thinking that Chu Feng was frightened by the opening of the formation and fled, so he didn't care, let go to the side, and Chu Zhenqiong walked into the palace from his side.

Chu Feng grasped the timing very skillfully, as long as he was a little late, he would definitely be discovered by him if he escaped only when Chu Zhenqiong stepped into the formation.

Chu Zhenqiong's face was as usual and he walked into the golden palace, and the palace gate slowly closed.

"Hoo ......"

Chu Feng heard the sound of the palace gate closing, and let out a breath, fortunately he was not exposed, otherwise it would be over.

When Chu Feng let down his vigilance, he suddenly saw a faint demonic aura left in the sky, leading from the golden palace to the depths of the canyon.

"This is the demonic energy that was just left behind."

Chu Feng looked at the slowly fading demonic qi in the sky, this demonic qi was very weak, if it wasn't for the fact that he was in a dangerous situation and cheered up his spirit, it is estimated that he would not have found the demonic qi that slowly dissipated in the sky.

"When Chu Zhenqiong returned to the Golden Palace just now, he specially opened the formation and plunged the heavens and the earth into a moment of darkness, could it be that he gave the person who left the demonic qi time to leave?"

Chu Feng recalled what had just happened, and combined with the remaining demonic energy in the sky, he had a bold guess.

"If that's the case, then I can't go to Ling'er now, I have to wait for that person to come out."

Chu Feng was scared, and used the effect of "Thousand Demon Faces" to hide his breath, and continued to hide in the cave, waiting quietly.

At dawn, Chu Feng sensed a demonic aura again, and then disappeared, he poked out his mind and took a look, and found that the formation of the golden palace was opened again, and Chu Zhenqiong left the palace and flew into the distance.

As soon as the formation was opened, a black shadow swept from the direction of the depths of the canyon to the sky above the golden palace and disappeared into the air, presumably using some powerful means to step into the palace.

Then Chu Zhenqiong left the palace, it seemed that he was going to the castle of the Heavenly Demon Abyss.

"Really!"

"The person who left the demonic qi is very likely to be the group of enemies who emitted the demonic qi, it seems that they are really hiding in the palace, with the help of Chu Zhenqiong's identity, hiding here openly."

Chu Feng saw all this happening with his own eyes, and gritted his teeth with hatred, Chu Zhenqiong was in the same league with this group of people, so was his father defeated by Chu Zhenqiong back then, was it also related to them?

Chu Feng's fists were clenched, and he clenched it so loudly, he would definitely find out all this.

Chu Feng suppressed the anger in his heart, knowing that now was not the time to act rashly, he wanted to rescue Ling'er as soon as possible, turning into an afterimage and sweeping towards the depths of the canyon.

Chu Feng came to the depths of the canyon and found that in the deepest part, there was a cave more than ten meters wide, and the entrance of the cave exuded a faint aura of formation.

Obviously, there was a formation guarding the entrance of the cave, and Ling'er's life fluctuations came from there.

"Ling'er is inside."

Chu Feng made sure that Ling'er was inside through the silver bracelet in his hand, he released his mind and began to observe the formation at the entrance of the cave, in front of him was a defensive formation, and the level of this formation was very high.

"It's a ground-level formation."

Chu Feng observed for a while and came to a conclusion.

The earth-level formation was already a very powerful formation for Chu Feng, but when he sensed the level of this formation, he was relieved.

Chu Feng originally thought that according to the strength of that group of enemies, the formation arranged was at least a heaven-level formation, but now it seems that maybe they are not very proficient in the formation, but they only know a little about it, so the formation arranged is only a ground-level formation.

It is also possible that they feel that there is no need to arrange too strong formations, because according to Chu Feng's guess, the people imprisoned in the cave are all women and children who have not used any cultivation, not to mention the ground-level formation, even if it is a mortal-level formation, it can trap them for a lifetime.

"Ling'er is in the cave, will there be danger inside?"

Chu Feng's heart was full of fog, from what he had learned before, he had determined that the person who captured Ling'er was the group of enemies who emitted demonic energy, but what was the situation in the cave?

Chu Feng had no idea what was going on inside the cave, it was likely that there were terrible enemies inside, it was possible that other secrets were hidden, or it could just be a place where women and children were held.

However, no matter what, Chu Feng still decided to try to break through this formation and step into the cave to rescue Ling'er.

Although there may be danger, Chu Feng promised that he would definitely rescue Ling'er, and the gentleman would not give up easily.

Even if he dared to break into the decent realm, how could Chu Feng be suppressed by the cave in front of him.

Chu Feng released his mind, it was very difficult to crack the entire formation, but if he just tore open a crack and let himself penetrate the formation and step into it, the difficulty would not be very great.

All Chu Feng had to do was to find out the eye of this formation, and then break through a formation to achieve the purpose of entering the formation.

Chu Feng can currently arrange a human-level formation, which is one realm worse than the ground-level formation, so it should not be difficult to break through a formation.

As Chu Feng's mind seeped out of the formation, it was observed that this array was very large, not only enveloping the entrance of the cave, but also extending into the depths of the cave, enveloping the entire cave.

"This formation only has the effect of sealing and defense, and it is just a formation for imprisoning people."

Chu Feng studied for half an hour, understood the structure of this formation a little, and began to break the formation.

It took Chu Feng two hours to break the ground level formation, and before he knew it, at noon, with the breaking of the formation eye, he could be sure of one thing, that is, the strength of the person who arranged this formation may be very strong, but his own formation attainment is really not good.

This formation seems to be extremely strong, but there are still some flaws in the tight places, for Chu Feng, who has strong soul power, it is like a bright light in the night, it is easy to find.

Boom~

Chu Feng smashed his fist on the eye of the formation, smashing the eye of the formation open, and a two-meter-long crack broke out at the mouth of the cave, and he took advantage of the gap in the crack repair to turn into a streamer and rush in.

Chu Feng burrowed into the cave and entered the inside of the cave, and when he came to the cave, he finally saw the real environment here.

I saw that in the bottomless cave, there were thousands of people imprisoned, all of them were women and children, and the moment they saw Chu Feng appear, their faces were frightened, and they shrank in the corner and trembled.

"Were you all captured?"

Chu Feng opened his mouth to ask, but this group of people may have been too scared, and none of them had the courage to answer him.

"Some of them are mentally depressed, and some of them are still in good spirits, could it be that the time of detention is different."

Chu Feng muttered, walked to a corner, squatted down and asked a little boy, and under his reassurance, the little boy finally let down his guard and told him that he had just been caught.
