Zhou Wen was already very familiar with Ant City. He didn't need to do anything as his mount, the Mutated Stone Chi, could finish off a large horde of black-winged flying ants and the flightless ants.
The low-valued crystals that dropped were of little use. The Companion Eggs that dropped were fed to his few pets as snacks.
Tyrant Behemoth was simply too gluttonous. Its appetite alone was comparable to Banana Fairy and Silver-Winged Sky Spider. Furthermore, it was only at the Mortal stage, but the phone often popped up a notification that it was hungry. This gave Zhou Wen a headache.
If it's such a glutton at the Mortal stage, won't it really be able to swallow a thousand mountains when it truly advances to the Mythical stage? Zhou Wen was worried if he could afford to rear this fellow.
