After a period of time, the old man in the lead brought the Great Magus and Leonhart to Mike's cave. After they sensed Mike's aura, which was getting stronger every minute, they left. Before they left, they also used a spell to wipe out Mike's aura, so that Mike could recover in peace.
Of course, Mike sensed the arrival of the three old men. Although he did not know the old man in the lead, he could roughly guess his identity based on the respect the Great Magus and Leonhart had for the old man. The old man should be the leader and guardian of the four Dragon Guardians Brothers.
