As his voice fell, he saw a white light shoot out from Fang Yuxin's wrist. Right after that, the transformed Lan Re began to gorge herself.
Lan Re was a mutated Crystal Orchid, a kind of saprophytic plant - zombies were food to it. After extracting the Crystal Core from a zombie's brain, the body was of little use to humans, and they mostly just burnt it. However, these remains were a great supplement for Lan Re.
Zombies' bodies also contained Energy, but humans simply could not absorb or utilize it. Lan Re could, so in its view, it was better to devour the zombies rather than burn them.
Bai Ye's face stiffened, but he didn't stop Lan Re from eating. Lan Re was Fang Yuxin's Spiritual Pet, and of course, he saw it in a different light. Plus, these zombies were useless to him, so there was no harm in letting Lan Re eat them.
