The school life of a destroyer

The story starts with our mc fighting a bunch of strong warriors. These warriors are known as the five "Omega Alpha".They are the five core elements in the starting of all things.At the other side our mc is the sole " Alpha Omega" sung-ji-han.He is known as the end of all things.However, due to all of his powers and skills sealed' he suffered fatal injuries .

Sung -ji-han:

"Are the five great omega alphas such Coward's. Fighting me by sealing my powers".

Creator(The first and the strongest OA):

"You have no right to blame anyone because it's your fault for being too strong.You can only blame yourself for not surrendering to us.we know that we can't kill you but we can seal you in the cube of eternal slumber. Now rot in that place for a few celestial years.

(1 celestial year=1000 septillion years)

Sung-ji-han:

" A bunch of low lives.Do you hear me, the day I will get unsealed will be the last day of your life"

As the creator had activated the cube,it slowly started swallowing ji-han but due the cube being broken,rather than sealing him it transmitted ji-han to a far away place known as earth.
