I Should Have Ascended Long Ago but I Am Trapped in the Mortal World

Yunfeng has been practicing with his master since he can remember. According to his master, he was adopted as his disciple when he was still in his infancy. Because of his innate intelligence and the guidance of such an expert as his master, he took the golden elixir when he was more than ten years old. It was hundreds of years ago when he reached the peak of divine transformation, but his final ascension has stagnated, and he has not been able to break through just a thin veil... The master has exhausted all methods to solve this problem, so the master also has a knot in his mind. He ascended to become an immortal. One day, his master changed his position and told him that he was about to ascend. In order to find a solution to Yunfeng's matter, he left a message: "A practitioner understands the destiny of heaven and earth, and can ascend after leaving the mortal world. But the disciple has never entered the mortal world, so why talk about becoming an immortal..." After saying that the master flew away, Yunfeng also determined to first enter the mortal world and then return to the mortal world in order to pursue the master's ascension... What kind of legend will the quasi-immortal enter the mortal world to create...
