The lizardmen were murderous, but that didn't mean they were brainless.
Their choosing the whale as an ally was naturally a calculated move.

With such concealment, once they had killed the realm lords of the four realms of Elixir, Instruments, Formations, and Talismans, they would have plenty of time to escape.
"You two want to exterminate our four realms?" Laozi asked.
The lizardman sneered, "Assisting your four realm lords can greatly enhance the strength of other worlds, destroying you is as meritorious as destroying ten big worlds."
While the task was to destroy a sufficient number of worlds, worlds differ in strength and importance.
