Ye Tian transmigrated through marvel universe as an orphan baby and grew up in china, which was very safe at least in novice period until thanos snapped fingers and then all great gods came to this world.
When he first came to this world he was panicked but gradually calmed down and accepted fate of being ordinary person except that he had extraordinary perception of everything and photographic memory which may be due to effect of transmigration.
This world has a background of Marvel Universe199999 still long before official start as it is still the year of 1992 and cuban missile incident happened this year and mutant academy is yet to be formed.
So professor X has not yet founded mutant academy but it won't take long to form it and jean grey still probabily hasn't experienced her friends death. Hulk vs abomination is yet to happen and Tony stark still hasn't started legendary journey of iron man and the start of marvel universe is yet to happen as there are still 16 years before 2008 when these incidents will start.
"Today is my 18th birthday since coming to this world and I'm still ordinary person, so cheers to myself." As a character knowing about great gods and crazy marvel universe I've remained unknown and little whiteface and I didn't even go to kamar taj as there is still price to pay for magic with soul and Instead of which remaining ordinary person is still good.
But I'm proficient in common firearms, martial arts and fighting techniques and some qi medition through which it is at least safe to deal with odinary people with firearms unless you meet superhumans.
Just as this sentence was said a golden fiery portal which he recognized and belonged to kamar taj appeared Infront seeing which he almost choked himself.
just then he heard " I can't predict your future and you are special in many timelines I've seen because you appear on in this timeline but from the moment you appeared in this world although you can change timeline but it won't change you in any way or the present world and it won't produce multiple timelines as if you are out of it and it is either someone covering up for you or because you yourself are unique. So Ye Tian are you willing to become my third apprentice and become a mage and protect earth."
Just as he was about to refuse, suddenly he heard a sound which he was eager to listen for who knows how many years.
[Ding- Omnipotent Conceptual System is activated and eternally binds to master. This system is Supreme Treasure of Absolute Nothing beyond any concept, and beyond the final box.]

4.Indestructible Loyal Artifact Quota.
5.Infinite Indestructible Omnipotent Dimension.
6.Infinity Contract.]
1.Eternal Immortal Soul and Infinite Resurrection:

2.Infinite Immortal Quota:
The same immortality is for those approved by you through Infinite Immortal Quota which is also Infinite in numbers.
3.Infinite Unrestrained Soul Defense Quota:
Infinite Unrestrained Soul Defense Quota means soul defense is infinite, not affected by anything and even cannot be sealed or affected by using any means such as time, space, reality, soul, and anything you can or cannot think of that exists is absolute nothing. Or it can even be said that any concept is invalid.
4.Indestructible Loyal Artifact Quota.
As for Indestructible Loyal Artifact Quota, it literally means anything other than living thing can be given the property of being indestructible and loyal to him or to those defined by him.
5.Infinite Indestructible Omnipotent Dimension:
Infinite Indestructible Omnipotent Dimension means this Dimension is infinite and Indestructible and will eternally exist in the Absolute Nothing and you are the god of it and it omnipotent within it being its sole anchor point. This Dimension will grow with the growth of host and host too will grow with it but initially it is one the size of earth and in future it will contain infinite omniverses and even infinite the box and even the unknown no. of the final box and finally the absolute void.
The Energy inside it will not decrease in level no matter what any how many times it's used up and it can only increase it's energy level. Theoretically master has infinite energy which will recover the next second it's completely consumed. But origin energy transformed is only one time and can only be accumulated by given means. Only Origin Energy is capable of being omnipotent and other energies or matter can only be transformed into one to another form or transformed into omnipotent origin energy and work correspondingly.
6.Infinity Contract:
Infinity Contract is the contract that even the true god of the final box cannot disobey. Any entity as long as it exists it must obey as long as it's signed. Only he the master of contract has power to breach or cancel unilaterally without any backslash.
"Yes master Gu Yi, the sorcerer's supreme. I Ye Tian hereby take the oath to become your and only your Master Gu Yi's apprentice eternally and protect you and infinite sentient beings in infinite universes. But I can't accept to bow my head to emperor weishandi because he's unworthy of me to do so. I only bow to you as a master and none."
