A week had passed by since Oh Kang-Woo and Kim Si-Hun encountered Nangong Chen. During that time, Kang-Woo focused on increasing the size of the demonic crystal inside him. He used the Heavenly Dragon Cultivation Technique even while eating, drinking, and sleeping.

His ability to control the demonic energy inside him was already at a level that no one could ever hope to catch up to. The shocking result was a result of Kang-Woo spending every second of the day cultivating. The demonic crystal grew in size every day, and he got used to using the energy inside it.

'But when will I achieve the Ultimate Demonic Body?'

The demonic crystal had become the size of his fist, but he still hadn't fulfilled the final condition.

'Well, I guess I'll fulfill it eventually.'

Even if he became anxious, nothing would change. The only thing he could do was place all his focus on it.

Kang-Woo checked his status window while using the Heavenly Dragon Cultivation Technique. His Demonic Energy stat was still at 103. He did not gain any demonic energy from cultivating.

'I guess it's obvious since there isn't any demonic energy.'

Unlike mana, it was impossible to obtain demonic energy through natural sources....
