Low-Level Cultivator: I Am Invincible by Breaking Through the Realm

Xu Qian, who was born at the bottom of the world of immortality, was found to have invalid spiritual roots and was unable to join the sect. From then on, he became a casual cultivator in Lingxiao City. He was trapped in the early stage of Qi refining for many years and was unable to break through. After returning from a serious injury, he awakened the Breakthrough Panel. Realm bottleneck? Doesn't exist. Can't you learn magic? If you persevere, you can always practice to perfection. Refining alchemy, refining weapons, making talisman formations? Sorry, I am omnipotent! Xu Qian rises from the bottom with an ordinary appearance, proves his way through killing, becomes immortal and invincible in the world!
