I Use the Demon Refining Tower to Become a Demon Saint

Fang An traveled through the world of Xianxia, ​​but became the weakest and slowest-cultivating willow tree demon among the demon clan. He was chased by three monks at the beginning. When he was about to die, he was bound to a golden finger called "Demon Refining Tower". He originally thought that this was a torture tool specially designed to restrain demons and that he would die, but he unexpectedly discovered that this tower could actually refine himself! By accurately controlling the intensity of "punishment", fatal torture is transformed into a supreme opportunity to temper the demon body! Refining the true fire of the sun, absorbing the supernatural powers of the demon clan, and awakening the innate bloodline... We, the demon clan, are no weaker than humans! The monks who were slaying demons were horrified to find that not only was this willow demon not afraid of fire or thunder, it could even chase them with the demon refining tower and shout: "Fellow Taoist, I want you to help me practice!" A generation of demon saints started from self-torture and rose up in purgatory.
