Reincarnating into the world of Jujutsu Kaisen, he became Gojo Satoshi, the twin brother of the strongest sorcerer, Gojo Satoru. That should mean he’s destined to be the most powerful Jujutsu sorcerer, right?Unfortunately, fate had other plans. Nearly killed by Satoru in the womb, his cursed energy was devoured before he was even born. But at that moment, he awakened the [Shinigami Fusion System].Since he couldn’t become a Jujutsu sorcerer, he would forge a new path, a Shinigami with Heavenly Restriction!Thus, Gojo Satoshi, born without cursed energy yet possessing the legendary Six Eyes, became the true nemesis of Jujutsu sorcerers.

【Your descendants in the Immortal Cultivation World have offered a plate of snacks】【Incense Fire Value +10】【Would you like to reward your descendants?】Yang Genshuo was surprised to discover that offerings in the Immortal Cultivation Family game could actually appear in the modern world, and that modern items could also be bestowed upon descendants in the game.Years later, peculiar rumors about the Yang Family spread throughout the Immortal Cultivation World.“To break through from the Fetal Breathing Stage to the Qi Refinement Realm, one needs to refine a strand of heavenly and earth's spiritual energy. I've heard of Red Flame True Qi, Xuan Water True Qi, and Green Wood Spirit Energy, but Yang Dao-friend, this... Liquefied Natural Gas, what kind of spiritual energy is it? How is it condensed?”“I've heard that the Yang Family's Spiritual Plant Technique is incredibly sophisticated, with each mu of Spirit Rice yielding twice as much as top-tier Spirit Plant Families, all thanks to a strange secret technique the family disciples cultivate called 'hybridization'.”“The Yang Family’s art of elixirs is unrivaled in the world, with new elixirs constantly being created. It is rumored that a spirit of the elixir named 'Artificial Intelligence' tirelessly deduces elixir recipes day and night...”“Nowadays, the Thunder Cultivators of the Yang Family are exceptionally strong, all thanks to the Yang Family's effort in creating a top-tier Thunder Gathering Array. Thunder Cultivators who enter this array can increase their cultivation speed multiple times. It is said that the array eye is known as—the power station.“As the Yang Immortal Cultivation Family grew stronger, Yang Genshuo actually became the only Immortal in the modern world by consuming offerings!Years later, facing an endless stream of people ascending the mountain to seek the Dao, Yang Genshuo calmly said,”There are no immortals in this world; you must believe in science!“Then he soared away on his flying sword.

One day, a silver-haired goddess appeared before him.“Heaven-Defying Star. The one who goes against fate. The sole savior of a world doomed to end—”What the hell is this woman even talking about?“You must be the Regressor.”“… What?”No, I’m not.
