The reason he didn’t use the Heaven Smiting Devil Slayer Sword before was not because he was arrogant. It was just as Duke Hui Ye had guessed, to avoid too much exhaustion. When he first got this Heaven Smiting Sword, it already weighed a hundred thousand kilograms. After consuming Dragon Fault, its weight increased even more. In a span of three months, even though he managed to get used to its weight and he could control it perfectly, every time he swung it, an enormous amount of exhaustion would soon follow.
The next opponents in this fierce battle would only be stronger than the next, so he had to do his best to avoid exhausting himself.
His current opponent was Hui Ye, but just based on the thickness of their profound energy, he was completely suppressed by Hui Ye if he did not open the “Purgatory” gate. However, opening “Purgatory” would exhaust his strength even more, which was why it was now time for the Heaven Smiting Sword to come out.
