Different from the Gate of Heaven, they attacked Han Fei not just because they hated Han Fei, but to prevent the rise of the human race. Therefore, these were actually two different things.
What they didn't know was that there was actually another Southern Dipper assassin who died in another timeline. Otherwise, they might have had to say a few more words.
It was no joke that the Southern Dipper was famous in the divine realms. The cooperation of those people just now was actually quite perfect. If it weren't for the Twin Divine Technique, they might have succeeded, provided that Han Fei didn't have the time to use the Great Dao of Life Borrowing.
Besides, if Han Fei hadn't taken the Dao of Extreme Balance, he might have been killed in the Void World.
