A boy in his 16's wakes up to the roaring sky. He was a boy that is Qi-less, he had 0 Qi, and could never get any Qi in his entire life.
His parents hearing about this they didn't want him. They had a younger child who was a genius. He has enormous amounts of Qi which was on par with Axis 49 cultivators.
The Axis system goes from 50 to 0, someone who is at Axis 50 can't even touch someone who's Axis 49 and so on. Axis 0 IS impossible to reach, none has ever done it before.
Our Mc, Mujin, he is what people of that world call trash. He had 0 Qi, he will never be able to cultivate into a powerful being who can even reach Axis 50.
He was abandoned at the age of 9 because his parents didn't want to be known as cultivators who had a child that had no Qi. He lived a harsh and troublesome life.
He, well Mujin could use something far more "powerful", he could use magic. He didn't need to use words for the casting, he could simply think of the magic he wanted to use and it would happen.
Mujin could learn really fast as he didn't need to focus on Qi cultivation and so on. So since his parents sent him to a deserted forest he stayed there and trained endlessly (not really, since the age of 10 till the age of 16 since at the age of 10 is where he found out about his power).
Mujin looked like a normal kid, he would hunt monsters down by choking them with his telekinesis or even teleport them really high up in the air and letting them fall. He had black hair, a face that was quite handsome and he carries a smell that would remind of the tree and grass.
Mujin had quite the muscle too, he looks like a bodybuilder, which is crazy for a 16 year old kid. He maintained a healthy lifestyle.
On a rainy night, Mujin heard someone knocking on his door, he used a magic he made specifically, "Observer", which allowed him to use his soul and look around freely, his body was invincible when he used it.
He sees a man at the door, he looked quite bloody, he goes back to his normal form, thus reconnecting his soul with his body, and goes to open the door. The man looked really bloody and tired. He looked like someone of a royal family, medieval like armour and a sword that didn't seem to match their world.
Unknown man: Hah, didn't your parents tell you to not open doors for strangers?..
After this the man fell to slumber, Mujin used telekinesis and put the man on this bed, but not before using telekinesis to remove the trash and blood from the man, he used a healing spell which he learned after falling really hard while using flight magic.
He healed him fully, he sat outside on the steps, waiting. A man came out of the woods he looked annoyed following the trail of blood.
He sees Mujin sitting and starts scratching the back of his head.
Unknown man²: Ugh, did we really have to involve a kid in this? It's getting annoying.
The man walks to Mujin, Mujin looks at him blankly with eyes that have 0 emotion. The man smirks.
Unknown man²: Oo, don't hurt me. Give me the man, the Tianxu empire needs to know his origin, he appeared randomly in our place. Get him out now kid.
Mujin stood, the man finally realising Mujin's build. Mujin with a soothing, a tiny bit raspy voice replies to the man.
Mujin: He is at my care, none shall take him from me till I allow him to leave or see it fitting for him to leave.
