Chapter 689: Ancestral-grade Realm

"Cooperate? Listen to three things?"

After thinking for a moment, Lin Ye cleared this thought.

There were too many people who would turn their backs on the other party.

Furthermore, it was not necessary. Why take the risk and find trouble for himself?

The moment they touched, the system sent a congratulatory message.

"Congratulations to Survivor Lin Ye. You have obtained 3,562 strands of fur from a member of the Sky Swallowing Race at the Intermediate Ancestral-grade Realm!"
