Shang cut off the front half of the tortoise, and immediately, the battle stopped.
Luckily, the true tortoise had been well in the back half since enemies tended to attack the chest and neck more often than the ass.
A moment later, Shang reappeared as he stopped using his Concepts of Light and Darkness.
"The fight is over," Shang said.
Then, Shang turned around and flew out of the Isolation Barrier. After the fight had ended, it no longer stopped him from leaving.
Shang's Spirit Sense locked onto the Thunder King. "I need some time to think, and I need to go back for a while. I will return later."
The Thunder King didn't answer. Apparently, it was still annoyed by Shang's earlier disrespect.
Shang simply took to the sky and flew towards the southeast.
On his way, he thought about everything he had just learned, and he realized something.
