章 491: Hidden Token, Confirmation Of Two Undercovers!

"This is?"

Lin Ye was curious and grabbed it in his palm.

He sized it up.

The token was not big, only the size of a palm. In the middle of the front was an engraving of a strange person wearing a mask.

On the other side, there was a series of small black dots.

There was a faint special connection between each black dot.

But he had no idea for the time being.

Other than that, the material of the token was also special. It looked similar to the material used to forge the 'Ten Thousand Dao Technique'.

Its entire body was pitch-black and had an extremely strong concealment effect. Even people with extremely high cultivation levels would treat it as a child's toy.

"This is good stuff. Hehe, kid, you might be able to use it when you go to the Underworld." Old Gu chuckled.

"What do you mean?"

Lin Ye asked.

"See for yourself." Old Gu shrugged.

As he spoke, a system notification appeared in front of him again.
