I Am Brushing up Copies in the World of Cultivating Immortals

After traveling through time and becoming a Qi-training casual cultivator at the bottom of the world of cultivation, Zhang Xu found that the world was hopelessly cruel. Spiritual stones, exercises, elixirs... Everything must be fought for with life. Until he awakened the "Copy System", everything changed. A secret realm that others would have to fight to the death to enter once, he could re-do it every day. He would always be able to reveal the opportunities, elixirs, techniques, and magic weapons that others dreamed of by using them several times. From the simple [Caiyuanzhai] to the legendary [Zhuxian Sword Formation], from the casual cultivator that no one cares about to the mighty power that shocks the world. Zhang Xu took a path that no one could understand—— While the entire world of cultivation was reeling from life and death, he was just leisurely... Brushing the daily dungeon. "Fellow Taoist, where did your ancient divine sword come from?" "Oh, I just got the Abyss Explosion. If you want it, I have three more in my warehouse."
