Chapter 688: The Seal of Zhong

"Thank you!"

Xiao Mu reached out and took the Black Jade Pendant, examining it carefully from every angle.

The material of the Black Jade Pendant was just ordinary black jade; it was hollow. At the top of the pendant, there was a tiny hole the size of a Formation Eye, which seemingly had been sealed with wax. Now, the wax seal had been scraped off, exposing the small hole.

A faint, ancient stench of corrosion wafted from the hole.

Xiao Mu nodded silently; by now, he had almost guessed what had happened to He Qingjun.

First, He Qingjun had found this Black Jade Pendant from some place, broken the seal on the small hole, and poured out the ancient blood from within, which stained his body.

The ancient blood in the black jade caused He Qingjun to undergo a Variant, giving him abilities that surpassed ordinary people, but it also led to his mental instability.
