Both the Whale Emperor and the Sea Serpent Emperor understood his intentions; he wanted to save the rest of his underlings.
The Sea Serpent Emperor had harbored an intense hatred for those zombies for a long time. After all, it was because of them that its previous attack had been thwarted.
This time, it aimed not only to kill Shaun but also to annihilate all the zombies.
Shaun remained calm as his body suddenly swelled, turning into a zombie giant that shielded the high-level king zombies.
He didn't choose to teleport himself away. While he could withstand the attacks of the two Emperor-level creatures, the rest of the high-level king zombies would surely be wiped out.
He had to buy time for the other zombies.
Meanwhile, he possessed the ability to rewind time and could leave at any moment. The urgent goal was to get the other zombies to safety.
