MTL - Return of the Net Gaming Monarch - Chapter 610 Olsen is here.

One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive. I had no choice but to strengthen my dungeon’s defenses in hopes of living another day—or at least that was what I’d thought. For some odd reason, I instead ended up spending my days in relaxation and bliss.

Reborn into the body of a poor young boy in an unknown village in another world, Lu Qing felt quite helpless.Fortunately, he awakened an ability to see through the information of objects, which gave him a bit of capital to survive.He looked at a weed by the road.[Cow bone grass, average quality, medicinal, highly effective in treating bone injuries.]He looked at a red carp in the river.[Red moon carp, excellent quality, delicious meat, a top-grade nourishing food.]He looked at a wild rabbit in the mountains.[Gray rabbit, ordinary wild rabbit, edible.]...With his innate ability, Lu Qing gradually established himself in the village, able to survive.Just when he thought he would lead a peaceful life in this ancient world with low productivity,one day, he suddenly saw a figure sweeping across the sky...

Entering the mortal world for a hundred generations, do not compete for the youth of one life, but only for the day and night of a hundred generations.

Seeking immortals in the world of mortals.

My name is Li Qing. I have escaped from the mortal world in the third life, entered the Tao in the ninth life, and become immortal in the hundredth life.

- Description from novelbuddy

King Grey has unrivaled strength, wealth, and prestige in a world governed by martial ability. However, solitude lingers closely behind those with great power. Beneath the glamorous exterior of a powerful king lurks the shell of man, devoid of purpose and will. 

Reincarnated into a new world filled with magic and monsters, the king has a second chance to relive his life. Correcting the mistakes of his past will not be his only challenge, however. Underneath the peace and prosperity of the new world is an undercurrent threatening to destroy everything he has worked for, questioning his role and reason for being born again.
