The demon that succeeds in killing the intruder will be rewarded by the abyss, so many demons are flying in the direction of the intruder. As demon gods, the reward is too small for them, so they didn't bother with it. 

However, they had to change their minds when word reached them about the intruder. It turned out that the intruder came to the abyss to fight a demon king who invaded his plane. The intruder succeeded in killing the demon king and he even destroyed the plane of the demon king.
