[Early Urban Cultivation] + [Earth + Alien World] + [Decisive Killing] + [Rebuilding with Pets] + [Emotional Drama with Multiple Female Leads] + [Revenge and Refreshing Article] + [No Literary Text, More Realistic] Chen Tianling, who is revered as the Heavenly Emperor by all the immortal emperors in the immortal world, was once an earthling. Although he practiced hard in the original immortal world for millions of years, he finally understood the mysteries of reincarnation, time, interface travel, and being superior to immortals. But the continuous pursuit of increasing strength is no longer the greatest meaning of his life. He still longs to do what he really wants to do deep down in his heart, which is to go back to the very long past, start over, and make up for the regrets along the way in this life. These regrets include those on earth, the spiritual world, and the fairy world... Grandparents, this time, I will spend your old age with you on earth... Junior sister, master, and those members of the sect who died tragically, I will never let tragedy happen again this time. Those who caused the tragedy of annihilating the sect, I will let you live as animals and slaves for thousands of generations, suffering endless torture and suffering. Demon Emperor, I won't let you have the chance to be cruel this time... Thousand-faced Demon Lord, do you think you can rest easy if you escape to the God Realm? You slaughtered countless immortals in the Immortal Realm, and even put down your face and destroyed all the small worlds related to me... This time, if I want to kill you, even the Lord of the God Realm cannot save you.
