No matter if it's the Six Dao or Hui Qilei, they are terrifying figures who regard all beings as chess pieces, so they wouldn't suddenly care about how many people on the Vermilion Bird star die. Hui Qilei is only concerned with the purpose of the Six Dao. He can feel that this purpose must be significant.
"Don't you plan to stop it?" Six Dao asked Hui Qilei.
"Stop it? Why stop it? Hehe, isn't this the best scenario? I'm also curious about your reason for opening the Underworld. Is it to rescue him?" Both Hui Qilei and Six Dao know who 'him' refers to.
"I won't strive for a failure," Six Dao replied.
Back then, the God of Great Cataclysm swept through the universe with invincible might, shaking the heavens, and even the Nine Heavens Daizihumo submitted to him. Hui Qilei was the same, but eventually, he failed. The God of Great Cataclysm was ultimately sealed by the combined forces of numerous immortal sages. Therefore, he is but a failure.
