These demons were slightly stronger than the demons he faced at the cultivation higher world. This was in his army capacity to deal with. Ibro continued to add more blood to his army.
The first 2 hours were intense as his army nearly lost half of its numbers. But, that came at the expense of their strength which got a huge boost.
His skeletons had reached the advanced differentiated stage. That helped in decreasing the death rate by a huge margin.
These strong skeletons had formed an impregnable wall in front of the incoming demons, which helped their weak comrades to get stronger.
Ibro was trying to reach this stage, so when he reached it he was sure of his victory here. As long as his weak skeletons got some time and protection to get stronger, no army can kill them.
