And so, Momoana died.

Shi Yichao: “Clear the mobs and stack skeletons! I shall bring the undead calamity upon the world!”

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?”
