In the battle between gods and devils in the past, the Devil Race’s attacks were very targeted. They would use every possible means to kill the leaders of all races first.

Once a leader was killed, the fighting strength of that race would be greatly reduced.

Therefore, after the last war between gods and devils, the leaders of all races were killed in battle, without anyone surviving.

To catch the thief, first capture the ruler. The two sides were very clear about this logic.
