Even the technology of the human race has never been detected.

In this black abyss, everyone can clearly see one terrifying monster after another.

These monsters are pitch black, huge in size, and covered with various sharp fangs and claws.

Fortunately, they were all asleep at this time.

Among these monsters, any one of them is far stronger than Chi Yan and his men.

However, in Lin Yu's eyes, it was not good enough.

In the eyes of Chi Yan and others, the extremely powerful monsters were actually just at the extraordinary level of strength.

And the mere extraordinary realm is just like a child to Lin Yu.

However, even though he had reached a deep enough depth in the cave, he still hadn't seen the treasure that Lin Yu wanted to find.

Helpless, I could only continue going forward.

...

...

"Teacher, do you want to go down?"

"These monsters are already so strong. If we go any further, will it be dangerous?"

Wang Dao looked at Lin Yu carefully and asked uncertainly.

Lin Yu replied: "Although the monsters here are strong, they are actually just ordinary monsters. Ten thousand years at most. I believe you should be able to deal with them!"

"When the time comes, I will also arrange for you to come here for training!"

When several people heard Lin Yu's words, their views were refreshed again.

Let them gain experience?

Come to the depths of the cave and use monsters as training objects?

And it’s a monster that is so powerful and terrifying?

Several people opened their mouths wide and looked at Lin Yu blankly.

If they didn't know how powerful Lin Yu was, they would really doubt whether Lin Yu was crazy.

When Lin Yu saw the expressions of the few people, he immediately understood their thoughts and said calmly:

"You are my disciples, Lin Yu. If you can't cultivate to this level in ten thousand years, it would be too shameful!"

"Don't worry, since the master said that you can come here to train at will ten thousand years later, then you can do it!"

"Even if you don't have confidence in yourself, you should have confidence in me!"

After hearing Lin Yu's words, everyone remained silent.

Obviously, they still didn't quite believe what Lin Yu said.

However, now I can only follow Lin Yu and continue to explore further down.

Finally, after half an hour, Lin Yu finally brought them to the deepest part of the cave.

Compared to the dark abyss we came from, the deepest part of this cave is completely different.

This place is simply a sea of ​​magma and fire!

Theoretically, there is nothing wrong with the fact that there is a sea of ​​magma and fire deep inside the earth, but the problem is that it is too deep.

To be honest, this is the first time Lin Yu has seen magma so deep underground.

However, what Lin Yu couldn’t understand was that after reaching the deepest part of the underground, he didn’t see those monsters.

At the same time, he didn't even see the treasure he had been looking for.

Everything seems extremely normal, yet extremely unusual.

"Teacher, what's wrong?"

"Is there something wrong?"

Cang Lei saw that Lin Yu's expression was a little abnormal, so he asked:

"It's not wrong, it's absolutely wrong!"

After Lin Yu finished speaking, he ignored his disciples and carefully examined the underground magma in front of him alone.

However, after looking around, I still found nothing.

"Is it here

Lin Yu looked at the constantly rolling magma and couldn't help but think deeply.

In order to verify this idea, Lin Yu made a decision immediately.

"You wait for me up there, I'll go down and find out what's going on!"

As soon as he finished speaking, Lin Yu casually summoned the Tiandi Xuanhuang Linglong Tower to cover all five people.

"While I am away, all of you should stay in this tower. As long as this tower is here, you should be fine!"

Without waiting for anyone to answer, Lin Yu flashed and completely entered the underground magma.

The five disciples looked at Lin Yu who had disappeared, and they couldn't help but feel a little panicked.

Just leave like that?

You are our master!

Just leave us like this?

However, they didn't even have the chance to bargain with Lin Yu and could only stay in this Linglong Tower.

However, not long after Lin Yu entered the underground magma, an old man with white hair and beard appeared outside Linglong Tower.

The old man looked like he had just escaped from some trouble, his face full of relief.

However, after seeing the exquisite tower, the old man couldn't help but be slightly surprised.

"Um?"

"The Heaven and Earth Mysterious Yellow Linglong Tower?"

"Could it be that my eldest disciple knew that I was out of trouble today and came here to pick me up?"

"But, that won't happen! My eldest disciple shouldn't have broken through to the Daozu realm yet. How could he have come here without breaking through to the Daozu realm?"

The old Taoist kept muttering to himself, and in the blink of an eye he arrived outside the Linglong Tower.

At this time, the five people in Linglong Tower also discovered the old Taoist.

In an instant, the five people were on full alert.

No one knows where this old man in front of me came from, and judging from his aura, it is impossible to tell his true nature.

However, since he was able to come here, he must be a top-level expert, and may not be weaker than their master.

Now, it seems that we can only place our hope on the Linglong Xuanhuang Tower of Heaven and Earth.

"Who are you?"

"Why did you appear in the tower of my poor disciple?"

The old Taoist looked at the people in the tower and asked calmly.

However, Cang Lei and the others remained silent.

Although they knew they were no match for the old Taoist priest, they believed that the old Taoist priest would be unable to do anything to them in the tower.

However, they completely underestimated the strength of this old Taoist.

After all, this person is the legendary Hongjun Daozu!

Even their master could only show respect to this person as a junior.

"Since you don't want to tell me, I can only check it myself!"

Hongjun smiled slightly, and then waved his hand lightly, and almost instantly moved them all out of the tower.

At the same time, almost in an instant, a thought flashed through their minds.

In just a short while, Daozu Hongjun actually read all their memories.

However, after reading all the memories of Cang Lei and the others, Daozu Hongjun couldn't help but smile awkwardly:

"So you are Lin Yu's disciple. I am sorry for being so rude!"

Given Hongjun Daozu's status, it was a rare opportunity for him to apologize to these people.

Several people looked at this Hongjun Daozu who actually knew Lin Yu. As the smartest among them, Chi Yan asked back:

"Senior, do you know our teacher?"

Hongjun smiled and said, "More than knowing each other, we have been friends for a long time, but we have never had the chance to meet!"

"Okay, since your teacher asked you to wait here, then just continue waiting!"
