Tang Zhen had killed the war devil because he was the strongest opponent he had ever met. If the war devil didn't die, then the one who would die would most likely be Tang Zhen.
He resurrected the war demon because it was still of great use.
Even though they were the same person in theory, there was a huge difference in their strength. This was also more beneficial for Tang Zhen to control.
In fact, Tang Zhen was very clear that even with the ability of a creator, it was impossible to completely resurrect a person.
Of course, this wasn't very important to Tang Zhen. In the end, the war devil was just an enemy. Tang Zhen was only giving his opponent the appropriate respect.
As the light dispersed, the war Devil's figure slowly appeared.
He opened his eyes and looked at the surrounding environment. After that, he glanced at Tang Zhen who was standing in front of him and helplessly shook his head.
