"Ten Thousand Demon Cave, what kind of place is that?" Ye Fei asked suspiciously.

In the two months he spent in Canglan Academy, he had almost understood everything he should have known, but he had never heard of the Ten Thousand Demon Cave.

"It's also a place of trials in the academy, but it's easy to get in and hard to get out, and some of the students who enter have been trapped in it for ten years before they get through the level and get out.

That place has almost become a forbidden area for the academy now, and no student wants to enter the experience, but cousin, you are different, with your strength, I think it will only take three months at most, and you can get through the level. Lin Feng said very easily.

"How can my cousin be so sure?" Ye Fei continued to ask.

"Liuyun has been in, he stayed in it for two months and cleared the customs, it is the fastest record in the academy for a thousand years, I think your talent strength is no worse than Liuyun.

He only used it for two months, you should be fine with three months, maybe it won't take three months. Lin Feng said with a smile.

"I don't know what the situation is in this secret realm of the Ten Thousand Demon Cave?" Ye Fei suddenly became interested, Senior Liuyun had been there, it was definitely not ordinary.

"The Ten Thousand Demon Cave is divided into ten floors, which is similar to the Phantom Beast Tower, but it is not a demon beast, nor a phantom beast, but a demon beast true spirit. Lin Feng explained.

"Demon Beast True Spirit?" Ye Fei was a little puzzled.

"My cousin knows that there is a realm in these heavens and ten thousand worlds, and it is called the underworld. Lin Feng asked.

"I know a little about this, it is said that the underworld connects the heavens and all the worlds, and receives the souls of all living beings in the world who live for the rest of their lives. Ye Fei responded.

"Actually, this is not the case, the underworld does accept the souls of the creatures of the heavens and all the worlds, but it only accepts the souls of the creatures above the immortals, and the realm does not reach the realm of the immortals, the underworld does not accept them. Lin Feng corrected.

"Why is this?" Ye Fei asked strangely.

"I don't know the specific reason, but it's an indisputable fact that the underworld only accepts the souls of creatures above the immortal robbery. Lin Feng shook his head and said.

"What does my cousin mean is that the true spirits gathered in the Ten Thousand Demon Caves are the souls of those creatures who have not reached the Immortal Tribulation?" Ye Fei understood.

"There are many places in the world such as the Ten Thousand Demon Caves, but wherever there is abundant yin qi, the souls of countless living beings will gather to linger until the true spirits collapse and completely disappear from the world. Lin Feng nodded and added.

"Since it is a place where the souls of living beings gather, why did it become the secret realm of trials in Canglan Academy?" Ye Fei asked suspiciously.

"It's just because these true spirits can strengthen the divine consciousness of immortal cultivators and make our soul power even stronger. Lin Feng explained.

"But there are thousands of immortal cultivators in the world, and there are a few who can cultivate to the level of immortal robbery, they will eventually die, and now devouring those true spirits will also become the food for others to strengthen their soul power in the future. Ye Fei suddenly became disinterested.

"Cousin, the reason why this Ten Thousand Demon Cave is called Ten Thousand Demon Cave is because it is full of the true spirits of the demon clan, and after our human immortal cultivators die, our souls have their own home. Lin Feng understood what Ye Fei meant, and said disapprovingly.

"Well, that's what I said. Ye Fei was relieved.

"There are ten floors in the Ten Thousand Demon Cave, and when the true spirit of the demon beast enters, it will be randomly teleported to any layer.

The first layer of yin qi is the thinnest, and the true spirit of the demon beast is also the least, and the second layer gradually increases upwards.

If the Demon Beast True Spirit is teleported to the first layer when it enters, most of the powerful ones will break through the barrier and enter the second layer, so the higher they go, the stronger the Demon Beast True Spirit becomes.

There are two so-called clearance conditions, the first is to kill the demon beast true spirit, use the soul of the demon beast true spirit to strengthen your body, and break through your own divine consciousness to the subtle realm, and the breakthrough required is about 1,000 to 1,200 demon beast true spirits.

The second is to collect ten Yin beads, each layer has different attributes of the Yin beads, and the required Yin beads must have one in each layer, and then the teleportation channel can be opened to transmit them.

The condition required to open the teleportation channel is to have a subtle sense of consciousness, so these two conditions must be met before you can get out, otherwise you can only be trapped in it all the time. Lin Feng introduced.

"Yin Zhu? What is that?" Ye Fei had never heard of this thing, so he naturally wanted to ask about it.

"Yin beads are a special material formed in the place where the yin qi is most concentrated, and the true spirit casts the necessary things for the physical body, and it is useless for the living.

Our former sages of Canglan Academy, after discovering this Ten Thousand Demon Cave, sealed it, and the true spirits of the dead demon beasts in the outside world could enter, but they could not get out.

Even if we human immortal cultivators enter, we must collect all ten Yin Beads and find the teleportation circle before we can activate the circle and come out. Lin Feng explained in great detail, and Ye Fei easily understood what he meant.

"What is the strength of the true spirit of the demon beast inside?" Ye Fei finally asked.

"The true spirit that casts the body with yin beads will originally be the strongest to reach the level of a fourth-level demon beast, which is equivalent to the realm of the god of immortal cultivators.

It's just that because of the formation suppression, their strength has been suppressed to the level of second-level demon beasts, which is equivalent to the life-killing realm of immortal cultivators.

However, their bodies and souls are not perfectly compatible, so the strongest is equivalent to the appearance of the Deadly Seven Heavens. Lin Feng explained.

"So weak, why are there still students trapped for ten years? If it's just this level, let alone Senior Liuyun, even if any one of the academy kills the Nine Heavens, he can easily complete the trial. Ye Fei said suspiciously.

"That's that easy, didn't you think of the number problem, as the saying goes, ants bite elephants to death, do you think you are surrounded by hundreds or thousands of demon beast true spirits, how many can you kill?" Lin Feng asked with a smile.

"If that's the case, let alone killing, your life will be gone. Ye Fei suddenly realized and echoed.

"It's not to lose your life, when you go in, the academy will give a teleportation talisman, the eye of the Ten Thousand Demon Cave is the land of the extreme sun, the true spirit does not dare to approach half a step, and the teleportation talisman can be teleported from any place in the Ten Thousand Demon Cave to the place of the eye of the array instantly. Lin Feng explained.

"Okay, then I'll go and break into this Ten Thousand Demon Cave. Ye Fei was intrigued by Lin Feng's description.

"There's no rush today, and it's never too late to go tomorrow. Seeing that he had successfully persuaded Ye Fei to give up going to the Vast Mountain Range, Lin Feng breathed a sigh of relief.

Soon after Ye Fei entered the Ten Thousand Demon Cave, Wu Cong and the Seven Elders gathered in the secret room again.

"He entered the Ten Thousand Demon Cave, do you want to send someone in to kill him?" the Seventh Elder was actually asking Wu Cong's opinion.

"It's not necessary, it's just right for him to enter the Ten Thousand Demon Cave, and it will be difficult for the Lin family to make a difference in the Nine Secret Realms in a short period of time, and we can just implement the plan. Wu Cong shook his head and said.

"But Ye Fei is a trouble after all, his talent is not much worse than Liuyun, if he is not destroyed before he grows up, the Lin family will have him in the future, I am afraid that our Wu family will not raise its head again. The Seventh Elder thought for a moment and said.

"We don't do anything, but we can kill people with a knife. Wu Cong said with a look of wisdom beads in his hand.

"How do you borrow a knife to kill someone?" the Seventh Elder's eyes lit up and he asked.

"Warriors. Wu Cong's eyes showed a hint of ruthlessness and said: "Although the Great Elder went to the Lost Land with the top level of the academy, his contract demon beast was left to Zhan Tian for safekeeping, I can persuade Zhan Tian to put the contract demon beast in the Ten Thousand Demon Cave, no matter how strong Ye Fei is, he is just an ant in front of the fourth-level demon beast." ”
