In Sun Wukong's heart, he had always harbored guilt towards Ji Meng and Ying Zhao, and of course, it wasn't limited to just the two of them. There were also others who had aided Sun Wukong in the final battle within the Pangu Realm, such as Zhu Jiuyin, Kunpeng, Bai Ze, and more. Sun Wukong was deeply grateful and guilty towards these individuals.
However, Sun Wukong had never had the opportunity to express his gratitude and repay them, for he had died after that last battle. When he awoke, he found himself in the Netherworld World, reduced to a remnant soul. But when he discovered that Ji Meng and Ying Zhao within the World Within the Golden Hoop Rod were unharmed, he was genuinely delighted.
