After being taken out of the Demon Sea by Qiu Niu, Zhen Congming had cultivated by Qiu Niu's side and turned into his human form by taking a Transformation Pill, which got him to the Transformation Realm without experiencing the Heavenly Tribulation.
After that, Qiu Niu wasn't in a hurry to teach him techniques. Instead, Qiu Niu only let Zhen Congming create fires and make elixir pills to toughen his mind, which was why Zhen Congming was barely at Zhen-level.
However, if Zhen Congming changed into his true form, even the Nascent Soul Realm cultivators on and above Fifth Heaven wouldn't dare to mess with him! He could kill them with ease!
It was because he was a top-tier demon beast - the black Kirin!
All the demon beasts in the Demon Sea made ways for him since none of them could defeat him! Zhen Congming had reached the Five-Petal Realm before reaching the Transformation Realm and going through the Heavenly Tribulation.
