Just like on land, as long as they are not bitten by zombie animals, those marine creatures are still normal marine creatures.

No zombie on land can rival the Zombie King Zhang Yiming anymore. For the Zombie King Zhang Yiming, to evolve to a higher level, he must absorb crystal cores of a higher rank than himself.

Zombie King Zhang Yiming desperately wanted to improve his superpowers, even though they had already reached a terrifying level.

In reality, he was not satisfied with his superpower.

The reason why Zombie King Zhang Yiming was able to become king was because of the powerful brainwaves in his brain, which he used to command the zombie horde.

Because he can command hordes of zombies, he doesn't have much desire to improve his superpowers.

It can be admitted that his current abilities are no different from those he had more than a decade ago.

Reality led him to choose to help his younger self from over a decade ago, and he was truly determined to bring peace to the world.

Making the world peaceful wasn't because he had a change of heart, nor because he cared about the world; it was simply because he wanted the world to be a better place because of someone's existence.

He understood that as time went by, the Earth would change more and more, and the creatures on Earth would become more and more powerful.

If you don't improve your own strength, it will be really difficult to protect someone on Earth.

To prevent past regrets from repeating themselves, Zombie King Zhang Yiming begins hunting zombie animals for the first time to enhance his superpowers.

During his more than ten years as the Zombie King, he had no one to protect and did not have much desire to improve his superpowers.

The reason he remained undefeated was because he could command tens of thousands of zombies.

Things are different now. He can't rely on zombies forever. How can those filthy zombies appear in front of that person every day?
