My Best Friend Is A Transmigrator

A young man dies, and his soul transmigrates into another world. With his new body, he starts his journey to the peak of the world. Okay, wait, wrong script... We've seen this countless times, the MC dies and transmigrates to another world(mostly cultivation worlds) and starts his/her journey to the peak. But... what about his/her friends in this new world? Follow the journey of Leon, who finds a shocking secret after his dead friend suddenly came back to life. The body of his friend was occupied by a soul from another dimension, a place called Earth. His normal life took a turn, and with a new conviction after witnessing the death of his friend, he will rise to reign supreme, with his new transmigrated friend, of course. **************** "According to Pythagoras Theorem, we should be able to..." "Wait! Pytha what?!" "Pythagoras Theorem" "Pytha... Forget it, you do you, and I'll do me. You can say whatever you want" ****************** "Come, my friend, let the face slapping begin!" Some moments later... Smack! "Shit! Why'd you slap him?" "You said face slapping, right? Well, I'm doing just that" "It's a figure of speech! It doesn't mean you literally have to slap them on the face" "Oh! You should have explained earlier" ************************ On their journey to the peak, they discovered another shocking secret, Leon's friend wasn't the only transmigrator.... *********************** P.S: Cover art is not mine, I just edited it. If you're the creator and you want me to take it down, let me know. Disclaimer: The story will revolve around the Main character and the transmigrator(something like a dual mc)
