And so, Purin died.

【…Maybe you didn’t hear me clearly, my host. I said court her, not cull her. Our next target–】

Shu Yichao: “Build the hive and spam the worms. My hive mind shall devour the world! Who can compete with me?”

【…】

Shi Yichao: “Halleluyah! I have finally gotten rid of every single one of them! Speaking of which, System, it has been a long time since you last spoke to me?”

【I’m tired. Just go and destroy everything.】
