Isekai Maou to Shoukan Shoujo Dorei Majutsu - Volume 7 Chapter 3 part5

Zero, a 35-year-old mercenary, after being betrayed by one of his teammates who told his enemy about him. He chooses suicide so that he can kill his enemy and his traitor teammate. After that, he was reincarnated into the world of magic, in the body of an 18-year-old teenager with the same name as him. However, his body does not have mana or the talent for magic. But with the help of the cultivation system, he has unrivaled power in the world and has a harem of beautiful wives.

A prestigious senior mechanical engineer in the industry, Xu Yi was sent to a world dominated by magic.

In a world with an almost non-existent industrial system, how can Xu Yi display his value?

When magic collides with modern technology, when magic merges with machinery, that is the beginning of this story.

Qin Chen was transmigrated to the Taiyi Holy Land where he became a servant in charge of sweeping the floor. However, on his 16th birthday, he was rewarded with a system where he was rewarded whenever he signed in at a new place.

When he signed in at the Empire Ruin, he was rewarded with the strongest Chaotic Holy Body and the Chaos Emperor Scripture.

When he signed in at the Demon Sealing Land, he was rewarded with the Probationary Royal Armies.

When he signed in at the Alchemy Palace, he was rewarded with the Divine-grade Alchemy.

When he signed in at the Herb Garden, he was rewarded with an Immortality Elixir.

When he signed in at the Empire Palace, he was rewarded with the Emperor-grade Divine Art, Revival.

…

Qin Chen thought he could just spend the rest of his life signing in at different places until he became invincible.

However, when the ruin of the Great Kingdom appeared inside the holy land, people from other holy lands, prestigious families, and even ancient empires gathered to defeat the All-Powerful Demon King who appeared with the ruin. The Demon King had killed countless people and had planned to destroy the Taiyi Holy Land.

Qin Chen was left with no choice but to step up. When he killed the Demon King with a single slap, he sighed, “Why do you guys have to force a mere servant to act?”

In the late years of the Daqian era, tyrants roamed freely, war erupted endlessly, and the people could not sustain their lives.After transmigration, Chen Jie finds himself as a drunken gambler with a pair of unfortunate sisters at home.The elder one, Su Yunjin, is his wife, and he also has a five-year-old sister-in-law, Su Yunrui.Their family is so poor they can barely make ends meet.Then suddenly, his beautiful wife comes smiling, bringing him a bowl of hot porridge.“Husband, I was wrong yesterday. Please have some porridge while it's hot.”Seeing the bruises on his wife's face, Chen Jie feels something is amiss.Ding~[Daily Information has been updated][1. Yesterday, you gambled away the last three acres of good land, beat Su Yunjin while drunk, and planned to sell the five-year-old Su Yunrui, to recover your losses.][2.
