The invaders should eventually be driven back, but there is still a possibility they will return.

It should have been a thousand years ago that the time for their comeback began.

The upper realm made preparations in advance, but still could not clear it away.

So, five hundred years ago, the passage was completely severed.

However, neither of the two barriers is as strong as the outer space-time barrier.

Once the other side breaks through the barrier and enters this world, they may also break through the passage again at any time and enter the upper realm.

She didn't think the people in the upper realms wouldn't have thought of this.

There are still many doubts.

However, when she looked back at the task panel...

The progress bars for Task 1 and Task 2 have moved forward a little more, indicating that her prediction was correct.

The progress bar for finding the source of the poison is currently only at 32%.

In other words, even if her hypothesis that the source of the poison was from the crack is correct, it is not comprehensive.

She stared at the details of the task.

'Find the source of the demonic energy and dispel its evil influence.'

Search, remove...

Suddenly, her eyes lit up.

Demonic energy has leaked in and is affecting the people of this world.

Does this mean that the quest's search for the source of demonic energy is not just about the place where demonic energy originates?

There is also a source of demonic energy that can rapidly pollute this world.

It turns out this person wasn't the source, but just one of the infected.

The real source should be the first person or other creature that was afflicted by demonic energy and successfully transformed into a demon.

She immediately turned to Fu Yuanbo and asked, "Could you tell me everything you learned at Luoshui Palace?"

A hint of understanding and speculation flashed in Fu Yuanbo's eyes.

Nodding, he recounted in detail his understanding of the Luoshui Palace and what he had seen and heard during his visit.

Actually, catching this half-demon was just an accident.

Fu Yuanbo was eager to get more information from Yun Zhiyi about how to break through.

Therefore, they planned to act quickly and infiltrate Luoshui Palace directly, secretly taking away four Luoshui Palace disciples of different cultivation levels.

But he soon discovered that there was a strange power within these disciples, which was very similar to the dark energy that had harmed his grandson and almost destroyed his cultivation level.

He immediately guessed that the person who did the attack was from Luoshui Palace.

So he decided to stay an extra day to investigate secretly.

Unexpectedly, he actually got a pleasant surprise from the spot he was waiting for.

He discovered that although the Palace Master of Luoshui Palace claimed to be in seclusion, several disciples would enter her place every so often.

Out of curiosity, he secretly followed them inside.

However, they followed them into an underground passage.

They discovered that there was an underground palace below.

There is a strange altar in the underground palace.

The altar felt dangerous to him, so he didn't approach it.

However, in a dungeon within the underground palace, they discovered this person whose power and appearance were both very strange.

He originally wanted to stay a little longer to explore the secrets of the Luoshui Palace.

Unfortunately, they were accidentally exposed, so they had to quickly leave with the half-demon and a minor leader who had chased after them from inside the dungeon.

His bodyguards, following his signal, immediately led the people they were watching and broke through the encirclement to escape.

If it weren't for the fact that they deliberately took a roundabout route to avoid being pursued by the Luoshui Palace and to mislead them in their search, they would have avoided the situation altogether.

Otherwise, Fu Yuanbo would have returned long ago.

After listening to Fu Yuanbo's story, Yun Zhiyi narrowed her eyes, showing great interest in the altar.

Perhaps she should find some time to go and take a look.

Her gaze then fell on the other person who had been brought back.

This person is a martial artist at the peak of the Acquired Realm.

Yun Zhiyi also checked his internal condition.

Like the two Luoshui Palace disciples beside Luoshui Xian, he also possessed demonic energy.

It must be because he used demonic energy to cultivate, which caused his internal energy to be tainted by demonic energy and transformed into demonic breath.

Once the internal energy in their dantian is completely transformed, they may become true demonic cultivators.

The demonic energy of the two disciples was very weak, and it hadn't even entered their dantian; it was just circulating in their meridians.

But this person's dantian has already been nearly half transformed.

Remembering what Fu Yuanbo said about this person being a minor leader stationed in the underground palace.

It seems that the altar was something that generated demonic energy.

However, this demonic energy is somewhat different from that on this half-demon.

In comparison, it lacks some purity, as if it has been mixed with other things.

If one is tainted by the demonic energy of this half-demon, one will likely, like him, slowly transform from a demon into a demon.

It's likely that Luoshui Palace used some method to transform demonic energy into something they could absorb and cultivate.

She took out a white jade talisman and slapped it onto the half-demon's forehead.

The talisman emitted a milky white halo, and then disappeared completely.

Fu Yuanbo's pupils contracted slightly.

The moment the talisman disappeared, he could no longer sense the demonic energy on the half-demon.

"I'll take this person with me first. I'll trouble you to interrogate this one for me, especially about things related to the altar, the more the better."

Fu Yuanbo gave her a deep look and nodded, "Leave it to me."

Yun Zhiyi then grabbed the half-demon and threw him outside.

A dark figure appeared, carrying the half-demon away.

Fu Tingchen had just finished his morning training.

When they returned, they saw the person being quickly taken away by a dark figure.

He knew that his grandfather and Yun Zhiyi were here, and he also knew that the dark figure was Yun Zhiyi's person, so he did nothing else.

As I walked into the courtyard, I encountered Yun Zhiyi, who was coming out of the house.

The two looked at each other.

Fu Tingchen nodded to her.

Yun Zhiyi gave him a deep look, nodded slightly, and continued walking away quickly.

She soon returned to the courtyard.

The person had already been placed inside the room by the shadow.

After she went in, she directly led the person into the space.

They threw it into the small house where Guan Mutong had been before.
