MTL - Blade and Sword God Sovereign - ~ Chapter 12, Terran, Demon, and Selangor

An ordinary (?) grandfather, Choi Chuntaek. In an effort to protect his granddaughter, he started the virtual reality game 'Arkstar.'

Then... he accidentally obtained a legendary class?

A next-generation virtual online game, a hardcore gamer, a glitch that shouldn’t have existed… By sheer coincidence, Meng Jingtian ended up being the sole player god in a game. Thus, while ordinary players worked themselves to death running missions for NPCs to win their favor, NPCs prostrated before him! While ordinary players almost vomited blood grinding for gear so that they could solo bosses, the king of divine beasts kneeled before him, willing to offer its life and worship him. And while players went to suicidal lengths to trigger random events and lucky encounters, transcendent beings came to find him so that they could offer their precious treasures as tribute.

After picking up a phone on the streets, Feng Yuchen was sent to the world of High School of the Dead. He, along with 100 people, have to travel through various worlds, fight and solve quests in order to survive.

Whoever dies in that world, would be teleported back to the real world without memories of what happened before and die in an accident one year later.

- Description from Novelupdates

Lin Wudao transmigrated and obtained an invincible system to bury corpses.

So long as he buried the corpses of the powerful, he got to take over what they had or what they touched as his bonus. What was more, those items he stood to win were the enhanced versions.

The minimum level was enhanced by ten times!

“You’ve buried the corpse of Jiang Taichu the Great Emperor. Your cultivation prowess just increased by 10,000 years!”

“You’ve buried the corpse of your fiancee, Jiang Qingxue. You get the essence of the immortal, which is enhanced by 100,000 times! It’s thus upgraded into the essence of harmony. You will become the Immortal Emperor after the extraction of it!”

……

Ever since he acquired this system, Lin Wudao had embarked on an invincible journey of advancing history and dominating the world.
