Re:Zero Kara Hajimeru Isekai Seikatsu - Chapter 71Arc 7, - “Water”

Just as a gamer found an overpowered skill book called ‘Item Upgrade’ in the hottest virtual reality role-playing game on Earth, something happened to the game’s system, causing his soul to leave his body and go to another dimension. Common sense dictates that he would be born anew then become the greatest overlord of this world by making use of his advanced knowledge. Not in this case! He was already dead. Only some fragments of his soul and that skill book managed to get into that dimension and merge with an ordinary common youngster called Bai Yunfei.

This was the enormous Tianhun continent, where humans could be said to have no limits. There was a group of humans here who could cultivate the power of their own souls then control their bodies, the natural elements and even other people’s souls with that power! These special beings were called — soul cultivators. Come witness how the several fragments of the dead inter-dimensional traveler’s soul and that skill book, which was not governed by the laws of this plane, were going to help Bai Yunfei become a legendary soul cultivator and craftsman!

An ordinary student, a wretched peeper, a cowardly teenager with a kind heart. In a terrorist attack, he inherited the knowledge of countless elites, embarked on a path of God Jagged Tu…

He is an artist!

He is a mathematician!

He is a psychology Doctor!

He is a master of fighting!

In fact, he is a man

Taken off raw site:

A wretched, dirty young man is working during the summer when he was caught up in a mysterious explosion. After that explosion, the young man is then left with the memories and knowledge of dozens of the world’s experts.

He has changed, his heart has become cold, iron-blooded. He became a killing machine, his mind turned mechanical, calculative. Everything goes according to his plans and calculations!

In this magical, slaughterous world, a door is opened for him…

“Block him.”“He's technically still my boss.”“Then block him with dignity.”The call ended again.And then started again.I let out a sound somewhere between a growl and a sob, then finally answered with the enthusiasm of a snail crawling through salt.“Yes, Mr. Walton?”“Have you changed your mind yet?”I collapsed onto the towel and gazed at the sky as though it might consume me entirely if I pleaded sweetly enough.“Do you ever take a break?” I asked, shielding my eyes with one hand.“You're avoiding the question.”“Because it's a dumb question.”He exhaled, the sound sharp and irritated even over phone. “It's not a dumb question. It's a business offer.”“It's a weird offer-one that I already said no to.”There was a brief pause, and I could practically hear him clenching his jaw through the speaker.“You are acting unreasonably.”“ Unreasonable?” I sat up. “I'm not the one drafting fake girlfriend contracts like it's a normal Tuesday.”“Isabella-”“Certainly not, Mr. Walton.” I mimicked his tone perfectly. “I told you I'm not doing it.
