Weapon seller in the world of magic

Ever since he was eight years old, when he heard that their ancestor was blessed by the divine beast Phoenix, Emperor Shang always had a wish that is yet to be fulfilled. He wanted to see a divine beast.

That simple wish made him become fascinated towards the beasts. If someone claimed to witness a new species somewhere in the wild or a dungeon, he would send a team to capture it.

But, as he grows older, he would only get worried about seeing one before he dies.

Unfortunately, to this date, forget about the mythical divine beast, he couldn't even see a glimpse of a beast emperor.

Now that he heard of the existence of an emperor-grade beast that is living inside the Imperial City, the Emperor couldn't stop himself.

He left the royal meeting chamber, dragging the Grand Secretariat along with him.

The General of the North who was usually stationed at the Imperial City at all times, Ye Yin was notified about it.
