Tang Ye felt a bit regretful deep down. Zombies can survive without food or drink for a month if they have enough energy, of course, assuming there is no combat involved.
As a Level 5 zombie, the energy stored in his body is enough for him to consume more than ten Level 4 zombies. But he hadn't cared about it since he ate some Evolution Crystals from Level 3 zombies half a month ago.
He also wanted to have his energy replenished at all times, but where could he find that many evolved zombies for himself?
When it comes to eating ordinary zombies, the massive quantity discouraged even Tang Ye. No matter if it were Tang Ye, Xu Haishui, or Ah Fu, the energy stored in their body had rarely ever been fully restored.
Even at the times when it did get full, it was during the lower stages, like Level 1 or 2. Back then, the energy replenishment was quite satisfactory. A few Level 1 evolved zombies would usually suffice.
