My Disciple Increases Her Summoning Level

After returning to the island, I no longer have much to do. So this time, I got permission to go to the enemy's base again and cause terror over there. But this time, I won't stay there for a long time.

It's useful because the enemy have to think twice before sending reinforcement. Though in the end, that base is not the main base.

They must have felt the mana fluctuation from another base. And from there, they let the people from that huge base to send reinforcement instead of coming from those other bases.

Maybe the main base is closer than we thought. But well, it's hard to find them.

Anyway, I attack that base once in a while. Just like usual, no regular schedule when I will attack. So they have to be wary at all time and won't be able to get enough rest.
