MTL - This Summoner is Outrageous - Chapter 13 he is so selfless

Beneath the vast and infinite starry skies of the universe, countless tribes engage in endless strife, and the flames of war remain unquenched.Rising from insignificance, he possessed no exceptional talents, except for the ability to draw upon the fruits of cultivation from the future.Yet, in a single night, he understood the Dao, and took a step that shattered the shackles of life.With but a thought, he grasped the universal powers, casually breaking down the barriers between spirit and reality.To him, even the most profound and enigmatic of secret tomes were as simple and dull as children's books.Still, he had to go back and fill in the gaps of his cultivation...Some appeared to be glorious, unparalleled geniuses.In reality, they practiced like mad in the shadows to repay their debts...

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.
