Monsters Descend: I Can Summon Pets Unlimitedly

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.
