MTL - Doctor’s Life Simulator - Chapter 326 Modified Blalock-Taussig shunt

When an S-class elite assassin-raised captain of a special ops suicide squad comes home from a high-stakes Africa mission, he finds himself offered something that could potentially set him up for life- a curious assignment that he could use to finally exit his days of war and slaughter.

Then placed into a high-school setting, Lin Yi is tasked by the chairman of a top-tier multi-billion company with bodyguard duty for non-other than his own daughter, a certain little Miss of said high-school.

His enemies, once ranging from drug lords, mafia bosses, political figures, and national leaders, are soon replaced with spoiled kids who happen to have rich papas and mamas, and Lin Yi finds his intense expertise and high-threat skillset misused, and very underwhelmed…

But he does get a harem cast as diverse as his old enemies, so Lin Yi decides that, for the sake of messing around with girls as an invincible entity in a down-leveled environment, leaving his bloody and death-filled war days behind is something he’d definitely want to strive for.

This was the motive for their first meeting.

Initially, Lin Mo intended to become stronger through cultivating diligently. However, he discovered that staying idle was more comfortable. Most importantly, he could level up by doing nothing! Since he could achieve his goals by lying idle, why would he trouble himself to stand and work?

Lin Mo transmigrated to a martial arts world and realized that he had no talent in cultivating at all. Fortunately, he awakened the Idle Upgrade System. He could become stronger by staying away from the rat race and enjoying life.

Lin Mo lamented, “It’s not that I don’t want to work hard, but truly, there is no opportunity for me to do so.” As such, the most bizarre Martial Arts Saint in human history was born.

What’s worse than finding out you’re that Louis XIV when you’re a baby?
