MTL - Mermaid Effect - Chapter 16

Roy’s life was nothing special. The only thing commendable was the last few moments when he saved a mother and her child from a drunk driver.
…
It’s really an egg! Damn it, what kind of monster have I become? Did I fall into Hell instead of making it to Heaven??
Join Roy as he ventures through various worlds with the Custom Made Demon King System—a system that allows Roy to draw anything he can imagine and create it through exchanging souls!

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.

No one is optimistic about the marriage between the most respectable man in Yun Cheng and the most disfavored daughter of the Mu family.

And now Eltanin must choose between the fate of his kingdom and his mate.
