Il-ryeong Hwang-heol

Nano Machine He was a middle-aged man with bandages all over his head with blue hair and eyes. Descent of the Demon God An elderly man with dark blue hair, many body markings, wrinkles and aged skin that sits on a wheelchair and has many needles attached in his body. Cho Yushin killed his lover, which made him hate MS Group more than anything else.

Nano Machine He had his heart pierced by Sky Flash. Cheon Yeo Woon thought he died, but Gulwon came and gave him the blood of the Flame Qilin, saving his life. He then fled with the Blade God Descent of the Demon God He trained for 1000 years, studying everything about the Demon God, all to take revenge on Cheon Yeo Woon. Around 350 years ago, he and the two other people who took Spirit Beast Blood discovered the last spirit beast in the world, the Imoogi. They fought it for half a day, and when they were exhausted, an ominous energy emanated from a man wearing a silver mask and a man with red brows, who suddenly showed up. The man in silver hair invited them to join forces, and revealed themselves as the Mu-seong group. However, they requested the core and corpse of the Imoogi in return. In the end, they fought, but even though Hwang-heol hadn't reached Heavenly Master at the time, they still suffered a crushing defeat in a few seconds. Hwang-heol barely escaped with serious injuries, due to Ma Hu-yeon and the other trying to stop them.

However, Cheon Yeo Woon revealed he was above Heavenly Master, and defeated Hwang-heol with the Space Sword. Cheon Yeo Woon spared him because it would be a waste to kill such a powerful person. Cheon Yeo Woon didn't remember him because he only saw Hwang-heol in the past covered in bandages. Hwang-heol told Cheon Yeo Woon about the Void Master realm, which Cheon Yeo Woon had already reached. Hwang-heol asked Yeo Woon why he didn't use the same technique he used to kill the Blade God, and Yeo Woon reveals that he knows Hwang-heol isn't immortal due to his aging state. Hwang-heol reveals that the Five Spirit Beasts
