Everyone: Is the Summoner Weak? I Built a Zoo

Reborn into an era where monsters are surrounding, evil is raging, and there are countless copies and secret realms where everyone is awakening. While Xi Ye was scratching his head in confusion, he awakened the summoner talent! The audience was sighing: a once-in-a-century talent! Summoner**? It doesn't matter, I have a good brain, good luck, and a system that sends out mythical beasts at the beginning. Just... How to activate this system? The moment the boss jumped in front of me... "Ding dong, it is detected that the host has reached level 8 and the system is being activated..." "Ding dong, congratulations to the host for acquiring the mutated SS-level beast - the Colorful Divine Deer!" "Ding dong, congratulations to the host for getting the summoned beast - the stone lion!" Why is my summoned beast either a deer or a *? Is this the legendary zoo? Xi Ye looked at the sacred deer at his feet, "Go and kill the boss on the opposite side!"
