Immortal Realm Invincible? I Win Half-Half

After transmigrating to the cultivation world, Li Zhou arrives as the head of Dao Tian Sect but is a useless cultivator with no aptitude. In a desperate situation, he awakens a divine system that grants a 50/50 chance for everything, yet he only has three days left to live. He must complete missions to extend his life and turn the tide. At the disciple acceptance ceremony, he spots a hidden gem among the crowd—a genius with an ice spiritual root—and humiliates the cold and aloof female sect leader in public, silencing the arrogant big shots mocking them. He destroys the Blood Refining Sect of the Demon Path and defeats the ancestral spirit's avatar, then one-punches the destined son of heaven and clashes with the Immortal Palace's virgin. Through gains and losses in his cultivation journey, he recruits disciples with extraordinary bodies, uncovering the shocking conspiracy of feeding demons and possessing others. Finally, he slays the ultimate villain, sees all his disciples become powerful, wins the heart of the cold sect leader with a secret promise, and ascends to the Immortal Realm with a carefree letter left behind.
