MTL - Movie World’s Archvillain - v7 Chapter 5 I want an explanation (second more)

King Grey has unrivaled strength, wealth, and prestige in a world governed by martial ability. However, solitude lingers closely behind those with great power. Beneath the glamorous exterior of a powerful king lurks the shell of man, devoid of purpose and will. 

Reincarnated into a new world filled with magic and monsters, the king has a second chance to relive his life. Correcting the mistakes of his past will not be his only challenge, however. Underneath the peace and prosperity of the new world is an undercurrent threatening to destroy everything he has worked for, questioning his role and reason for being born again. 

When Li Fan transmigrated into a new world, his life seemed unremarkable. He was moderately well-off, with a wife and children, but nothing extraordinary. Everything changed upon his death, when he awakened the ability Return to Truth: the power to virtualize an entire lifetime’s worth of experiences, run it as a simulation, and return to the age of twenty armed with that knowledge.With this ability in hand, Li Fan finally saw a chance to pursue the dream he had always harbored: eternal life. In other words, the path of immortal cultivation.But the world of cultivation was nothing like the paradise he imagined. After countless generations of cultivators plundering heaven and earth, the heavens had struck back. Mortals now carried the Immortal-Mortal Miasma within their blood, a disease that, when encountered by cultivators, led to cultivation decline and death. No technique could be practiced by more than a single person. Calamities descended from the Heavenly Dao without warning.In such a hostile world, where even the heavens themselves resist immortal cultivation, can Li Fan truly seize eternal life? Or will he meet his final end, his Dao dispersing back to heaven?

- Description from xbiquge translation

In the year 2025, humans awakened with the ability to summon mighty beasts—capable of destroying terrains, breaking the laws of physics, and creating wonders limited only by one's imagination.But before these blessings came a curse.An alien face appeared from nowhere and threatened all life on the planet, leading to the greatest war in human history.In the aftermath, the human race and the alien race were forced into a shaky treaty that could be broken at any time.Years later, tests for summoning abilities began for the next generation. Those who awakened low-grade summoning would be thrown to the gutters, while those who awakened higher got to join great factions after graduating from the academy.Kairos Veyl, the blank, calculating student, pulled his hand from the massive crystal pillar and stared at the large beast before him.“This kid—he just got a LEGENDARY SUMMON.”A legendary summon? The greatest class of summoning. However, with this class came a risk one would have never guessed.
