To think that the knife would actually cause his cleaver to resonate...
The middle-aged man narrowed his eyes. After taking a closer look at the knife, he was quickly taken aback. It was no ordinary knife, but a very rare knife from Valley of Gluttony. Not only was it a spiritual sagacity blade especially used by masters to polish blades, but it was also impossible to find it outside the Valley of Gluttony.
Simply put, even the Supreme Blade Tyrant's Slaughter God Blade was merely a spiritual sagacity blade. He had managed to obtain the blade by going to the Valley of Gluttony with the required materials and having a master forge the Slaughter God Blade.
With the Slaughter God Blade, the Supreme Blade Tyrant's combat power and strength had increased significantly; he had used the blade to slaughter countless spirit beasts, even a Divine Beast.
