One day, the city underwent a drastic change. The entire city passed through to another world.
When the communication was cut off, all the people in the city received the hint of a system. With the summon book, everyone can summon different creatures. Therefore, people took their summoning creatures to take risks outside the city and found that as long as they killed a creature, they would have the chance to turn it into the summoning thing of the summon book! However, when Ethan woke up from the hangover, he found that the creatures sealed in his summon book can be used to synthesize higher price creatures.
An ordinary goblin turned into a powerful goblin mutant!
The drastic change brought crisis and opportunities to the city. How did Ethan and his best friend become the new rule-makers of the city?

Ethan raised his hand. At the same time, Moore, Freya, and Harries dispersed the condensed magic element in their hands.


To be honest, it was good to have a target to vent.


The three girls looked relaxed and happy.


"You have seen the results of so many experiments. There is only one way to erase me, and that is to kill the last devil king Seurat. Otherwise, when my strength grows to the point of breaking the seal forcefully, it will be the time when the last devil king is integrated with me. At that time, how terrifying is the last devil king who can fully use the summoning book? I couldn't imagine that."


"Now he can't use the summoning book? I also saw him call out the summoning book."


Ethan remembered the last time when he met with Seurat, who called out the summoning book.


"It's just a summon! He can't use the thing in it at all because he is not the soul of that world at all."


Kujo Shingo pointed out "the soul of that world."
