Facing the Apocalypse with My Other Selves - Chapter 137 - 105: Unleashed Killing Spree

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?

As a naive teenager, he was unaware of his own superiority.Shang Xiaojie realized the violent man who had tricked him into a hotel was actually his brother-in-law.He struggled and tears streamed down his face as he pleaded, “Let me go, you idiotic beast!”“I may be foolish, but a beast? Can’t you at least admit to that?” he asked.After drugging Shang Xiaojie, he callously taunted, “You’re just a male prostitute who comes running whenever I snap my fingers. You’re nothing, Shang Xiaojie.”Devastated, Shang Xiaojie swore, “Mussaf, I hate you and I’ll make you regret this.”Upon his return five years later, he was accompanied by a young boy.Shang Mingming asked, “Is that man my father?”Shang Xiaojie responded coldly, “No, I don’t know someone like him.”Furious, Mussaf demanded, “Where are you taking my son?”Shang Xiaojie grinned and replied nonchalantly, “I’m getting married to another man. There’s nothing you can do about it.”

Chen Xiaoyun, an orphan from Guangzhou, China, once met a girl who looked remarkably like him. Before he could learn more about her, a deadly virus was unleashed around the globe.Humans turned into creatures straight out of video games and movies, and zombies and mutants roamed the streets with no one to stop them.From tanks to jockeys to even invisible zombies and mutated dogs. The mutations are just endless.“Why is there a zombie apocalypse just as I find my family? And why can I suddenly create things from thin air?”Will Xiaoyun survive the chaos with the new people he meets along the way? Will he use his newfound abilities to bring peace to a devastated world?Or perhaps he will just take another nap in the bed like a lazy pig——“Shut up. How am I supposed to do anything when you keep throwing women at me?”

“Hero, where are you going?”“To eat.”“Hero, where are you going?”“To the bathroom.”“Hero…!”“…”The woman who followed me everywhere… Ended up following me all the way to Earth.———A former hero who returned to Earth, now unemployed and just lazing around at home.Then, the saintess who came with him made a suggestion—“How about streaming?”“Hmm… This might actually be a good idea.”And so, the Hero & Saintess Healing Stream begins!
