Yechen believed that if someone broke into this place by mistake and touched the prohibition here, even a level eighty-nine Contra level master would be killed in an instant.

What is in it that deserves such a terrible ban from the top of the academy?

Is it really just a top-of-the-line material with dark attributes?

Yechen looked at Lin Lao, who had brought him here with him, and found that the other party's expression was also extremely solemn, as if he was in deep thought.

In her mind, the words of the old man who was about to die sounded: "Our time is running out, I want to ensure that before my soul returns to heaven and earth, Xiao Chen's generation can grow up as soon as possible and become the new backbone of the entire continent......"

……

'Mu Lao, I hope your decision is right. ’

Lin Lao sighed faintly in his heart, and an incomparably pure soul power condensed in her hand, injecting it into the prohibition of the quaint small door in a strange way of operation.

That's right, this matter was planned by Mu Lao, in order to help Yechen speed up his growth.

As one of the largest trading platforms on the mainland, the Treasure Pavilion has collected countless resources over the years, and there are naturally top-level materials with ice and fire attributes in the inventory.

It's just that when Mu Lao learned that Yechen wanted to forge weapons, he specially explained to Lin Lao and wanted him to come here to give it a try......

Yechen didn't speak during the whole process, just watched quietly, he believed that Lin Lao would not harm himself, so he was not too nervous and worried.

It's just that when the seal on the small door was completely unsealed, an extremely strong energy fluctuation came to the face, and even through a door, you could feel the dark and cold aura inside.

Even the soul guide lamp in the corridor behind the two of them seemed to have lost its effect, and the world in Yechen's eyes became dark.

Caught off guard, Yechen's second martial soul Taiyin Youying was automatically released, and two pairs of huge butterfly wings converged forward, naturally beginning to absorb this dark energy.

And the strange thing is that after this energy was absorbed into the body, it was not actually converted into soul power, but turned into a strange energy, hidden somewhere in his body.

It's just that he doesn't know exactly where this place is......

The energy fluctuation only lasted for a while, and the corridor regained its calm again, and after the Taiyin Shadow Martial Spirit of Yechen couldn't feel that kind of energy, it gathered up and returned to its body.

It was like a momentary outburst in the room on the other side of the door, where something had been restrained for too long.

Lin Lao obviously knew that such a scene would occur, so he didn't show any panic and gently pushed forward.

The small door made a creaking sound, and it felt extremely permeating.

When it finally opens completely, it reveals a pitch-black entrance that looks like a gate to hell.

"Let's go, let's go inside."

Lin Lao turned his back to Yechen and walked in first.

Yechen hesitated at the door, but finally relented and stepped in.

......

On the other side, Ma Xiaotao led Huo Yuhao and the three of them to complete the registration and went to the location of the Inner Court Disciples' Treasure Appreciation Club alone.

Huo Yuhao and the three of them were not familiar with her after all, so they just politely thanked her, and walked around this floor together.

Wang Dong thought of the news that Yechen told her when he was leaving, and regardless of Huo Yuhao and Xiao Xiao's surprised eyes, he walked directly towards the central position.

As for the things like those natural treasures at the counter passing by, she didn't even look at them, and just skipped them.

In the end, Wang Dong came to the most central position, in front of a counter that was obviously more luxurious than the surroundings, and the three of them stopped one after another.

In the display case, there was a golden-red strange soul bone suspended there, which looked like an arm bone, and five slender phalanges pointed upward, each fingertip exuding a faint golden-red light.

'Is this what he wants me to find, it's actually a soul bone......

After seeing this soul bone, Wang Dong felt that it must be suitable for him.

'It's just that how did Yechen know that there was a soul bone suitable for him here?' ’

......

On the fourth floor of the Treasure Pavilion, Yechen followed Lin Lao's footsteps and stepped into the room behind the quaint small door.

With the soul power of the extreme dark attribute in his body, such an environment is very comfortable for Yechen.

Through the endless darkness, Yechen saw at a glance that there was a half-human-high object in the open space in the center of the room.

Yechen couldn't tell if the object was metal or something else.

It was as if it had been polished by something, and it was very smooth and black without a trace of impurities.

What's more, although it constantly exudes a dark aura around it, this darkness is extremely pure, and there is not the slightest evil mixed with it.

"Xiao Chen, let me tell you a story."

In the silent room, Lin Lao's faint voice suddenly sounded.

Yechen nodded, he knew that with the other party's cultivation, he would definitely be able to see it.

Sure enough, after Lin Lao paused, he began to preach again.

"Thousands of years ago, the Sun Moon Continent collided with the Douluo Continent, and the seniors of the academy at that time had just led the soul masters on the original continent to smash the ambitions of the Sun and Moon Empire, but at this moment, a strange thing happened."

He was still very clear about the history of the mainland, but he had never heard of this strange thing.

In fact, not only Yechen, but now all the members of the Sea God Pavilion, including Mu Lao, don't know what this matter is.

"At that time, the situation on the mainland had just stabilized, and everything was developing in a good direction, but the Seagod Pavilion Master of the Academy suddenly disappeared mysteriously, and there was no clue about his whereabouts."

"In order to prevent the situation on the mainland that has just stabilized from getting out of control, the remaining elders urgently convened a meeting of the Sea God Pavilion and forcibly suppressed the matter, only claiming to the outside world that the Pavilion Master was injured in the war and is recuperating in retreat."

The more Yechen listened, the more curious he felt, he didn't expect that there was such a thing, this was already the real top secret of the academy, right?

Without further thought, he was going to keep listening.

……

"After being missing for five years, the Pavilion Masters of that generation miraculously returned to the Poseidon Pavilion. He was already seriously injured at that time, and only this thing was left, and there was still a word to ......"

Speaking of this, Lin Lao finally turned around and looked at Yechen with a thoughtful gaze.

"What's that?"

Just when he heard the critical moment, Yechen saw that the other party was unexpected, and he couldn't hold back his curiosity anymore and asked.

"When the owner of the Extreme Dark Martial Spirit appears in the academy, give him the magic stone."
