This substance can't kill the World Tree, but it can delay its maturity.
If Shi Wanyun really injects this according to the other party's intentions, delaying the World Tree's maturity by a few days might not be a problem.
"Hmm..." Keke lay in Xu Xin's arms, tilting her little head to look at this agent.
"When can you communicate with them?" Xu Xin directly put away the virus agent and asked Shi Wanyun, "Today? Or did you receive it last night?"
"There were clues last night," Shi Wanyun said softly, "That mysterious voice didn't contact me last night, but last night I could communicate with survivors from other regions in the world channel."
Xu Xin was shocked: "Are you the only survivor in Area 1?"
"I believe I'm the only one," Shi Wanyun nodded, "And last night I already knew part of their plan. I didn't tell you because the risk of exposing my identity was too high."
Xu Xin first frowned, then nodded.
Her caution was understandable.
