The situation has somewhat exceeded his estimation. He hadn't expected that reinforcements wouldn't have arrived by now. Du You felt that the Hellfire Thunders, created by the magic power he had previously deployed, were almost spent.
Without the support of Hellfire Thunders, Du You could only flee this place.
He calculated that there were more than two thousand third-tier ground mechas on the enemy's side that were already incapacitated. But their backup was still coming, and at an increasing pace. Unlike demons that could be powered by his magic, these mechanical weapons did not have a strong defense. They were very much a restraint for him.
Even with the assistance of Dark Spirit Light to help him recover, his magic power was soon to be less than half of its original capacity.
The underground Death Scorpion was also seized an opportunity and was bombarded by the enemy. If it weren't for its resurrection ability, it would have died by now.
