After cultivating in the pyramid for almost half a year, Zhang Tie's cultivation base advanced by leaps and bounds. He had made great improvements in the battle skills of "Fire Dragon Sutra" and forming his earth chakra.
Half a year ago, Zhang Tie had just reached 1 change black iron realm; however, he had already entered the 4 changes black iron realm now.
Half a year ago, Zhang Tie could only simulate the battle skills of "Fire Dragon Sutra" according to the powerful emperor-level classic "King Roc Sutra"; however, now, Zhang Tie had been able to combine his gnosis with the deduction of those powerful secret battle skills such as "Fire Dragon Heavens Burning Spear Battle Skill", "Big Sun Fire Dragon Palm Skill" and "Fire Dragon Light Concealment Skill", which were very powerful.
Zhang Tie gradually mastered the essence of those secret battle skills of "Fire Dragon Sutra".
