The true demons didn't pose a threat to Ibro as he was high in the air. He was guarded by endless lines of his skeletons. The problem came from those who had demon seeds in them.
The seeds began to rise on the surface and started to coalesce together. Not all of them did so, as some preferred to attack Ibro directly. Ibro had to divide some focus to fight these demons.
That made him take longer than expected in forming his rune. The system didn't stop by as he activated the seal function at once.
It didn't activate any more functions or divine abilities so it wouldn't deplete more of Ibro's SPR energy. These 5 minutes were very stressful over Ibro, but when he finished writing his last rune he felt great relief.
He had finally completed the hardest part of his plan. What remained now was to hold his position and bide his time against those strong demons.
