The Alien Emperor's Son's Dark Prison suffered his first defeat against a peer of the same age on the Fifth Trial Continent, and it was at the hands of the strongest young supreme of the Combat Saint Lineage from the rival Ancient Universe. After his defeat, he remained dispirited for a long time and only truly recovered after decades.
After that battle, the Combat Saint King withdrew from the Ultimate Ancient Road. Although the Emperor's Son's Dark Prison longed for revenge, there was nothing he could do.
Later, the Combat Saint King entered the Ultimate Ancient Road, while Dark Prison entered the Supreme Ancient Road, making it difficult for them to meet for another battle.
