The seal weakens roughly every thirty years, and this Heavenly Demon Secret Realm contains many incomparably precious treasures.

It was originally a place ruled by a demonic sect in ancient times. This place is full of dangers, but it has an extremely special environment that can grow incredible natural treasures that do not exist in the outside world.

Therefore, every thirty years, humans, demons, and cultivators of the demonic path all flock to it to compete for treasures.

No one is an exception.

Because it was within the territory of the Qin Empire, the five major sects of the Qin Empire would naturally not miss this opportunity.

As the current head of the Ten Thousand Swords Sect, Lu Chen naturally has to participate in such an important matter.

Therefore, the training naturally came to an end.

There's nothing to say about that.

After hearing Bai Shaojie's explanation, Lu Chen was also helpless.

Lu Chen wasn't really interested in this so-called Heavenly Demon Secret Realm. It was too dangerous, and even with his current strength, he couldn't say it was absolutely safe.

Of course, if you encounter danger, you can hide in the Demon Suppression Tower, or even the White Cloud Palace cave is extremely safe.

But if you get stuck in it and can't get out, then it's painful.

"Alright! Let's go back then."

Seeing everyone's expressions, Lu Chen knew there was no room for negotiation. Although he was the sect leader, he couldn't act on his own whims at this moment.

The next morning, the group set off to return to the Ten Thousand Swords Sect.

Along the way, Lu Chen inquired in detail about various information about the Heavenly Demon Secret Realm. At first, he was not very interested, but after hearing other people explain it, he suddenly became somewhat tempted.

After all, this time when the Heavenly Demon Secret Realm opens, it won't just be the strong people of the human race entering it; even experts from the demon race and the demonic sect will participate.

Lu Chen originally wanted to go to Black Dragon City, but this time Black Dragon City would probably send its demonic beasts into the Heavenly Demon Secret Realm as well.

This is a perfect opportunity.

For the sake of the Ten Thousand Swords Sect, this trip to the Heavenly Demon Secret Realm is a must.

Most importantly, this Heavenly Demon Secret Realm possesses an extremely special treasure, which is of immense benefit to cultivation and cannot be found anywhere else.

That is the Heavenly Demon Stone.

"The greatest use of the Heavenly Demon Stone is for refining weapons. A large piece of Heavenly Demon Stone can be used to refine a top-grade spiritual weapon."

It should be known that top-grade spiritual artifacts are extremely precious. Even a major sect like the Myriad Swords Sect doesn't have many top-grade spiritual artifacts.

Lu Chen obtained a top-grade spiritual artifact, which was personally bestowed upon him by his ancestor.

No one else has it.

However, Lu Chen had devoured that top-grade spiritual weapon himself, and it was really difficult to tell that ancestor about it.

Lu Chen pondered that since this Heavenly Demon Stone possessed such incredible energy, perhaps it could also be devoured by his Chaos Divine Body.

I have to go and search this Heavenly Demon Secret Realm no matter what; maybe I'll find something unexpected.
