The Old Monster Asked Me to Be His Landlord

[No time travel + single female protagonist] There is only one innate Taoist body among ten thousand. Once the sect's genius attained Taoism, it should have skyrocketed. He never expected that the junior sister who had been with him for three years would pierce his heart with a sword and seize his bones on the day of his breakthrough, thus ending his path to immortality. With his cultivation completely ruined and his meridians broken, he dragged his body to escape, but was targeted by a thousand-year-old remnant soul. The old monster wanted to seize the body to be reborn, but unexpectedly failed to seize the body. "I will teach you how to rebuild your foundation, and you will come back to the world on my behalf." From then on, a useless man whose bones were taken away and his life was abandoned, took the soul of a thousand-year-old monster and embarked on the road of revenge. He didn't know that there was another soul awakening in the jade token he carried with him.
