When Yuan Yi heard this, his memory immediately returned to when he was still a little monk of the Eight Consciousness Realm, at that time, he met the head of the Hades Demon Sect, the elders of the Corpse Demon Sect and the elders of the Snow Demon Sect, and found the Heavenly Demon Strategy, the supreme treasure of the Demon Dao, in the Ten Thousand Demon Caves.

The Ten Thousand Demon Cave is a common holy place in the minds of all Demon Dao sects, every time it is opened, it is explored by many Demon Dao sects, and the demonic energy inside is extremely rich, and countless evil demons are bred from it, and there are many dangers, but there are also a lot of demon treasures, as long as you can come back alive after entering, you will definitely be able to harvest.

Yuan Yi hurriedly said, "The junior Demon Refining Sect cultivators are not, how can they enter the Ten Thousand Demon Cave."

"This is my Hades Demon Sect's guest token, from today on, you are the guest of my Ten Thousand Demon Sect, among the Demon Dao, there is no lack of physical cultivation, they are naturally also a member of the Demon Dao, and they are naturally qualified to enter the Ten Thousand Demon Cave."

When Yuan Yi heard this, he knew that the body refining holy relics were not so easy to take, and the Keqing token was not so easy to take, so he hurriedly asked, "Senior, the heavenly and earthly spiritual objects, the predecessors can't get them by themselves, but there are some terrifying demons guarding them."

"You can see clearly, that's right, there is an evil demon comparable to the Mahayana period guarding me, and the strength is above me, so I can't get the spiritual object."

When Yuan Yi heard this, he was taken aback, the evil demons of the Mahayana period were like tigers in a place like the Ten Thousand Demon Caves, but it was not Yuan Yi, a little monk of the Heavenly Ear Realm, who could afford to provoke him, so he immediately refused, "How can the younger generation be able to deal with the evil demons of the Mahayana period, and ask the seniors to ask for another master."

"Don't be in a hurry to refuse, I will entangle him when the time comes, you just need to cast the law of space, sneak into the evil devil's nest, and steal the treasure out, you are not your demon monk, in which ten thousand demon caves are easy to be eroded by demonic energy, go crazy, I can give you a life-saving talisman, so that you are not afraid of demonic energy erosion within an hour, when the hour comes, whether you succeed or not, I will break open the ten thousand demon caves and send you out, you don't have to worry about your safety."

Moreover, in that demon's nest, accumulated over the years, there is more than one treasure, and when the time comes, except for the treasure I want, the rest will belong to you, how about it, this business is cost-effective, I will treat you favorably for the sake of you being a friend of the head."

The old devil's words are very clear, it is for the sake of the face of the soul slasher, that he talks so much nonsense with you, otherwise, you have to go if you don't go.

The old demon is already very kind to him, he is not a person who does not know good and bad, and he knows the price of rejecting the strong man of the Mahayana period, so he immediately responded, "That good senior, I will do my best when the time comes, and I will help you retrieve the treasure."

"Very good, although the demon is powerful, but it does not know the law of space, when the time comes, with my protection, you will definitely be in danger, you don't have to worry about me breaking my word and getting fat, even if you other monks have always thought that we are cruel and cunning, but as a strong person in the Nirvana Demon Tribulation Period, I still disdain to deceive you as a junior."

"Thank you seniors".

Because of this incident, Yuan Yi couldn't leave immediately, so he couldn't help Zi Yan condense the Buddha Yuan, so he simply taught him the method of physical cultivation and let her exercise her body first.

After he knew about Yuan Yi's matter, he said, "The First Taishang Elder has always had a bold personality, and you don't have to worry about it, although he will follow him into the Ten Thousand Demon Cave when he comes back."

Even the soul slasher said so, Yuan Yi has no reason not to go, he is now eager to improve the cultivation of the physical body, his arm strength has reached eight thousand catties, as long as he can increase another two thousand catties, then he will be able to abandon the iron rod and wield the powerful demon pestle.

Yuan Yi didn't know if refining the dragon ball that didn't know if it was a dragon ball or a real dragon ball could help him improve his cultivation, and the body refining elixir in the old demon's hand was drowsy.

The Ten Thousand Demon Cave was opened, and after more than three months, Yuan Yi was in the guest room, cultivating for three months, consolidating the immortal art that had just been cultivated for a short time, and when it was opened, this time it was out.

The opening of the Ten Thousand Demon Cave is the top priority of a Demon Dao Sect, if you want to enter, the lowest one must have the Demon Infant Period, and then the Ten Thousand Demon Caves have different cave entrances, different cave entrances to enter, the danger inside is different, and the harvest of treasures and precious Cheng Dù is naturally completely different, therefore, when the time comes, the people of the Demon Demon Sect will not enter a cave together, the Demon Infant Period will enter a cave, the Yin Demon Period will enter a cave, the Yang Demon Period will enter a cave, the Liangyi Demon Tribulation Period will enter a cave, and finally the Nirvana Demon Tribulation Period will enter a cave.

Although Yuan Yi's cultivation is not very high, he has to enter the cave that belongs to the Nirvana Demon Stage with the First Supreme Elder.

This Hades Demon Sect, those who belong to the Tribulation Period belong to the level of the Old Ancestor and never show up, and then next, there are the first, second, and third Supreme Elders, that is, the three major Nirvana Tribulation Demon Period cultivators of the Hades Demon Sect.

The second and third Supreme Elders saw that the First Supreme Elder was carrying a burden, so he asked the reason, and after learning that he was a person who was proficient in the laws of space, he acquiesced, this time it was opened, and the three Supreme Elders had their own goals, so although they would rush to the Ten Thousand Demon Cave together, they would not go together after entering.

The other disciples are all gathered in the square and go together, every time they go to the Ten Thousand Demon Caves to open, the sect protection array will be opened with all their might, so as not to let someone take advantage of the fire to rob, and not all of them will go, except for the three people in the Nirvana Tribulation Demon Period, the others, one third of each realm is allowed to enter, and the other two-thirds of the people are responsible for guarding the sect to prevent foreign enemies from invading.

There are many crises in the Ten Thousand Demon Cave, so not everyone is eager to go, only a small part of these two-thirds of the people don't go if you can't compete for a place, and the rest feel that it's too dangerous to take the risk, so they don't go.

Ten Thousand Demon Cave, is a mountain, on weekdays will be hidden into the ground, only at a certain time, will rise, and then the hole mouth is wide open, then the demon monks can enter the inside to explore, some people have figured out the Guò earth shield technique to go down to the Ten Thousand Demon Cave, but none of them have come up, everyone has a lesson, will obediently wait until it rises before going.

When he arrived at this Ten Thousand Demon Cave, Yuan Yi immediately shuddered, he had never entered, he could sense the monstrous demonic energy inside from far away, it was worthy of being the holy place of all Demon Gate monks, even if he didn't look for treasures after entering, he found a safe place to concentrate on cultivation, it was worth the trip!R1152
