Prehistoric: Starting from Pangu's Fourth Brother

Transformed into the fourth son of Pangu Yuanshen, Sanqing has already announced his name in front of me. The eldest brother, the second brother, and the third brother all worked together to help me refine my body using the Heaven Opening Merits and the Spirit Gathering Formation. Lingbao Tianzun wants to cut his own origin to save me, and the Supreme Master even brought out the Life Pagoda - I will catch this brotherly love first!
