Ibro focused mainly on summoning the dragons and liches here. Although he needed soldiers in that gate world, he lacked commanders the most.
So, he started a summoning fever that lasted for one week, during which he summoned countless of his commanders.
The system continued to move any extra force that could be spared from the fight all over Ibro's 50 worlds.
This world which contained the damaged gate was filled with skeletons to the degree that no demon could set foot on it and lived the next second.
Ibro checked the situation in his world via his divine sense to feel content with such a result.
His skeletons stretched over the horizon with no end, such numbers were enough to set up a solid base there. Ibro was ready to move out, so he looked to Maya as he said:
"You should stay here."
"Oh, you are worried about me, that's sweet."
