MTL - Time Traveling: the Only Beloved Husband - Chapter 58

Liola—the best assassin in his world—has vowed to kill no more. He was being chased by an assassination organization when he accidentally dropped into a parallel universe: through a dimensional gate and into poor teenager Kaiser’s apartment. Instead of going to the government shelter for lost dimensional travelers, Liola and Kaiser wind up going to school together.

Liola has been trying his best to live the life of an ordinary person, but after certain things happen one after the other, he begins to realize that being an ordinary person could be harder than being an assassin.

In a world where life energy fuels martial prowess, Shen Yifan, with a mere mortal lifespan of a hundred years, finds solace in slaying demons to extend his own vitality. Amidst the chaos of a realm teeming with malevolence, he brandishes his blade, striking terror into the hearts of creatures who have roamed the earth for centuries! Yet, amidst his valiant exploits, Shen Yifan sometimes ponders, why does his lifespan seem to dwindle faster with each use of his powers? Sheathing his sword, he gazes skyward, hearing tales of the divine palace in the heavens, where immortal beings dwell, having weathered endless eons. Embarking on a celestial journey, he seeks to beseech the gods for a loan of a million years, to pave his path towards eternal life.

Dao Fa leads to spirits, and medical therapy leads to ghosts.

A third-rate university graduate who was supposed to run around in a mess for his livelihood, but because of an inadvertent shot to save people, whether it is extremely peaceful and rewarding for his good people, he has obtained the legendary inheritance of the mysterious arts and medical methods of the experts in the realm of self-cultivation. Another brand new and weird new world!
