3 hours later,
It looks like the situation of those Monsters somehow changes. As the defense and the attack system of the barrier was already killing those Monsters it became difficult for those Monsters to keep attacking the mansion.
Even though many people have already become as happy as they thought with this, those Monsters would get killed in no time; all the elders and even Sam know that this is not over.
The mastermind still did not appear in that place, and also, you can see the number of those Monsters did not decrease even though they continuously got killed by the attack system of the barrier.
This means the mastermind has the spiritual energy to continuously summon those spirit animals even though they have been killed by the attack system of the barrier.
The main question is how long will the mastermind be able to do that? Unfortunately, nobody knows the answer, and Sam is also waiting for that.
