The Empire of Gods in All Heavens and Worlds

In his previous life, he was a gang boss, but because his most trusted brother betrayed him in order to gain power, he was killed by himself. And he fainted from exhaustion. But when he woke up, he found that he was already in a different world with its own system, and he was still a lord. See how he builds an empire in another world, attacks the heavens, and turns those heavens and earth into his own territory. Please don't scold the newbies.
