Putting down the Pan Gu sword, Ji Hao made the star steps as he raised both fists and approached Great Uncle.
Ji Hao didn't want to hack Great Uncle straight to death, but the Pan Gu sword was too lethal. Therefore, he planned to exchange some moves with Great Uncle with his pair of fists, to see how exactly powerful was the so-called 'original eight magics of devil'. Earlier, through the short battle between Great Uncle and himself, Ji Hao surprisingly discovered that this 'original eight magics of devil' seems to be profoundly meaningful.
Not to mention anything else, since Great Uncle managed to free himself from the thunder cage by chewing a little finger of his, that escaping magic he used must be powerful.
