But the reason why Ye An took this thing out so early was not because of his grandfather's words, but because of Yang Zhitong's words.

The purpose of the person who erased the traces of murder for her is this key.

No, to be precise, what this key opens.

That's why she just took it out.

Obviously, the people behind it controlled Yang Zhitong in order to let her get this key.

But this key is in the hands of his grandfather again, and even in Ye An's memory, there is no existence of this key. Therefore, it is even more impossible for Yang Zhitong to get it from his grandfather.

After returning to the base, Ye An took out the key from his neck, looked at the wooden box in front of him and frowned.

She flipped it, and the box looked like it was wooden, but it was actually a metal composite. This kind of metal compound, even if it is buried in the ground for tens of millions of years, this box may not be destroyed.

She plunged directly into the keyhole, and the moment she opened the box, her spirit suddenly trembled.

The moment a ruby green stone touched the air, it emitted a faint green streamer, but the light was only a flash, and it quickly turned into a bland appearance.

Ye An was stunned for a moment, picked up the green stone, and squeezed it in his hand.

In an instant, the spirit became more than doubled.

There was a hint of joy in her eyes, this thing was what she had been looking for, a foreign object that could strengthen her abilities in this time and space!

In the last days, in order to strengthen one's abilities, in addition to constantly stimulating the potential of the body, there is also a way to strengthen it through external objects.

But that kind of foreign object is extremely rare, and once this kind of thing appears on the black market and is sold, it will attract competition from all sides.

From a scientific point of view, it means that there is a certain substance in these things, which will chemically react with the cells of the supernatural person's body to form a new qualitative change and strengthen the resulting abnormal ability.

Unexpectedly, the secret hidden in this key turned out to be this!

However, why does grandpa have this thing, does grandpa know about the existence of the supernatural?

But Ye An's body itself has no powers, and it has not awakened. So it's impossible for Grandpa to know that he has a special ability.

And according to her several conversations with her grandfather, she didn't hear a bit of tone from it. Or is it that Grandpa only knows the preciousness of this thing, but does not know its true function.

Also, those who think of getting the keys......

Ye An's eyes were fixed, and he didn't continue to think about it. Since this thing is in his own place, the person who should come to the door will come to the door sooner or later. She's not in a hurry either.

She knotted the green stone again and hung it around her neck. The coolness of clinging to her skin instantly made her whole body feel refreshed.

She couldn't wait to reach out and focus.

In an instant, several things in the room began to fly in the air, constantly changing positions in the air.

And this time, it lasted five minutes.

Ye An withdrew his ability, and everything immediately returned to its place, with a hint of satisfaction on his face.

The combination of an external object and an ability with an enhanced ability is only once, and after one time, the thing loses its effect on the body. If you want to strengthen it again, you can only look for it again.

Therefore, after now, this stone is just a stone for Ye An.
