The Great Emperor Abandoned the Pass and Went from Protecting the Human Race to Slaughtering the Common People

[Fantasy + Invincibility + System + Revenge + Decisive Killing] Two hundred thousand years ago, Su Han used his mortal body to prove the Tao against the heavens and became the supreme emperor. He guarded the borders of the human race, resisted the invasion of foreign races, and protected the peace of the human race. Two hundred thousand years later, the human race continues to have internal disputes, and they actually point the finger at the Su Han clan, intending to exterminate them to avoid future troubles! "Emperor, save me! The human race wants to destroy the entire Su family!" The clan members' wails echoed across the sky. The reborn Su Han was furious. He had shed his blood for the human race, but what happened in exchange for this? That's it! It's okay if we don't protect this human race! Su Han was disheartened and awakened the "enemy-killing system". Since then, he has abandoned the border and allowed the aliens to wreak havoc, vowing to make the humans pay the price!
