Apocalypse: Absorbing the Energy of All Things from the Start

Transmigration + crystal-core harvesting + unlimited skills + power fantasy + no romance + no saintly heroine After transmigrating to Earth a century into the apocalypse, he finds a world overrun by zombies and inhabited by mutated plants and animals. Humanity has grown weak and helpless. By chance, he obtains a fragment of a cultivator's spiritual consciousness, granting him the ability to absorb the energy of all things under heaven. So he kills mutated beasts to level up, then kills zombies to level up. He goes from a scrawny, useless human to a powerful ability user who can shelter his family from the storm. Chen Ming discovers that his energy system is unlike anyone else's in this era. He can absorb not only crystals, but also plants, zombies, and even humans... While others have to expend enormous manpower and resources to gain a level, all he needs is a blade of grass. After accidentally wiping out the largest family in the base, he becomes its strongest fighter. He thought he could lie flat and enjoy life in the apocalypse, but the greater his power, the greater his responsibility. When the zombies attack, he has no choice but to lead the army into battle. He expects a brutal fight, but in one fell swoop, he absorbs the entire century-old stockpile of the zombie horde... He becomes the bloodsucker feared by every zombie.
