MTL - Richest Man: Divine-Grade Reconstruct System - Chapter 1154 Good start

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

“CLICK-CLACK.A message notification sound broke the dormitory's silence.The message contained only four characters.Ban Feng, save me!”In order to save a friend's life, Li Banfeng had gone to Platform 96, boarded the 1160 Steam Train, and arrived in Puluo State, which lingered in the steam era.After getting off the train, Li Banfeng felt like he was the most eye-catching man on the platform—truly radiant. He even had the distinct illusion that his body was emitting light.“Mommy, that man has light on him!” said a child behind him.He stood there, frozen.“Sir, what's wrong? Sir? Sir… You haven't been touched by the Heavenly Light, have you?!”

Wei Huo has been ignored and overlooked by almost everyone his entire life, including God. In a bid to transform the world into a more game-like one, God halted time for all humanity except for Wei Huo, leaving him to fend for himself.

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!
