With just this weak beast tide, there was no way the lightning sura guarding the city would suffer any damage.
To a level 6 creature, these beasts were even less than a group of ants.
Even creatures of the same level as level 6 were no threat to the lightning sura who had already undergone undead transformation.
The current Frost could easily defeat the lightning sura, but it would be a little troublesome to kill it.
After all, the lightning sura already had the characteristics of an immortal body, but it was still unable to withstand the frost power's freezing which was like a sealing technique as well.
In conclusion, these wild beasts did not need to be controlled. They were just enough to be used as souls for the Sea of the Dead.
This way, his summoning power would increase.
