Eegoo is a former Paragon of the 33 Heavens and was among the first wave of army that attacked the Mountain and Sea Realm. He is a character with several major appearances in the latter half of the novel.
- “He bore the appearance of some fiendish beast, covered with scales, with a long tail stretching out behind it. He even had a horn sticking out of his head, which radiated a spectacular energy. Furthermore, black flames flickered around him, and his eyes were bright red.„
He was eventually trapped by Meng Hao into becoming his puppet with the help of Choumen Tai and the soul of, possibly, Su Ming. Although formerly a Paragon, Eegoo could only use around 70% of his strength due to Meng Hao, at that time, only having 70% of the divine sense of a 7-Essences Paragon. He fought against Xuan Fang, alongside Paragon Sea Dream. He was almost destroyed multiple times but managed to pull through long enough to be able to recover.
After Meng Hao returned to the Mountain and Sea Butterfly to visit those he cared for and pay respects to his family, he eventually visited Eegoo who was still sitting cross-legged at its appointed area since Meng Hao's command for it to protect the Mountain and Sea Butterfly 2000 years ago . Meng Hao had commanded the puppet to do so just before he was almost killed while protecting the Mountain and Sea Butterfly from the Immortal God Continent and The Devil Realm while it was desperately fleeing after the war with the 33 Heavens in order to relocate itself within the Green Coffin Vortex. However upon reuniting with Eegoo, with Meng Hao being transcended, he immediately realised that although Eegoo was still a puppet, he had actually regained his consciousness and was aware of who he was since 500 years ago. Meng Hao eventually released the puppet seals on Eegoo after determining that he had atoned for his sins during the 33 Heavens war.
Surprisingly, because Eegoo had been a protector of the Mountain and Sea Butterfly for so long, he had a change of heart and viewed it as his second home and decided not to leave even after being released from the puppet seals. This was especially because of the way he saw how much the Mountain and Sea cultivators respected him, a respect that was genuine even though it was only a puppet at the time.
