Fantasy: Immortality Starts with Modifying the Rules

[Rule modification] + [Rebuilding the human race] + [No heroine] Demons are rampant and humans are feeding on them. Once Su Xiu traveled through time, he faced the threat of becoming two female foxes at the beginning. He doesn't mind if he practices, but it would be rude to kill him! Fortunately, what he saw when he opened his eyes was the cold heaven that governed everything in this world, which could be changed by writing a pen. [The rules are reversed, the cultivation is reversed] Therefore, after a hearty training session, the fox girl was shocked and angry to find that their century-old cultivation base dropped rapidly, while Su's cultivation base increased sharply. [The definition of flesh and blood is rewritten, the feast eats itself]: Before the feast of the demons started, they were already burned by their own cultivation. [The bloodline shackles are replaced, the Dao fire is first ignited]: Seize the source of the aura of all races and ignite the immortal fire of the human race. ['The human race is for food', the rule of heaven is erased, and the words and laws follow] After that, Su built the human race's holy city, destroyed the foundation of the demon race, established the human race's great road, broke through the blood-eating world, and promoted the entire clan. The iron laws of the old world have collapsed, and what I say is the way of heaven. When the last heavenly rule was rewritten, the world fell into absolute silence. Standing on the ruins of rules, Su Xiu became the only eternal person in this world. Loopholes.
