MTL - Heaven Defying Supreme - Chapter 137 Selection begins

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.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.

Ye Chen transmigrated to a parallel world. In this world, everyone who was 18 and above would enter a chat group named Monster Chat. From there, they would summon their pets.Each person only had 10 chances of summoning pets and one chance to form a bond with a pet. Right at this moment, a voice rang in Ye Chen’s head:[Ding! Successfully activated the Unlimited Summoning System.][Congratulations for summoning pet: Dark Princess (level 8)][Congratulations for summoning pet: Alchemist (level 7)][Congratulations for summoning pet: Female Asura (level 7)][Congratulations for summoning pet: Goddess (level 9)][Congratulations for summoning pet: Demon Fox (level 10)][Congratulations for summoning pet: Nyuwa (level 10)]……This was an era where humans, monsters and pets coexisted. This was also Ye Chen’s era.

The world experienced a cataclysmic change, and countless spatial gateways appeared out of thin air.

Exotic beasts of all shapes and sizes swarmed out of those aforementioned spatial gateways, forcing the humans to face the crucial moment for their survival.

In order to search for a chance at survival, brave warriors from the army and scientific researchers risked their lives and entered the world beyond the spatial gateways. To their surprise, they discovered that there was a chance of obtaining beast cards by killing these exotic beasts in their world.

Those with extraordinary spiritual strength are able to utilize the beast cards, perhaps transforming the cards into the beasts’ combat bodies while they were still alive, or transforming them into weapons or defensive gears, or…

A new occupation came into existence following the changes, known as beastmasters.

A transcender with two souls fused into one found himself in this magnificent new world full of waves, rising step by step as he ascends into the seat of a godly beastmaster.
