The Promised Useless Start, You Reached the Top of Dao Ancestor?

Tang Ling traveled through the world of immortality and was detected to have a once-in-a-century waste spiritual root. At the beginning, he was sent by the sect to mine for ten years and was humiliated. At the end of the ten years, he returned to the mortal world with a ring full of waste mines and just wanted to live a stable life. Who would have known that those waste mines would transform into priceless spiritual treasures in the mortal world. He lived in seclusion in the mountains and forests, growing flowers and grass, until his former masters from the same sect came to hunt him down. As he waved his hand, the opponent was shattered into pieces by the sword energy emanating from the weeds in his yard.
