In the Age of Demonic Beasts, I Contracted a Flying Sword from the Start

So, what's this story about?

It's about a man who transmigrates to an age of demon beasts and, for one reason or another, makes a pact with an ordinary longsword. Then he awakens a System. The System gives him a Heavenly Forging Hammer and a Dragon Subduing Mace.

And then he becomes awesome.

With the Heavenly Forging Hammer, while everyone else struggles to upgrade their weapons once, he upgrades his several times in a row.

When others finally manage to upgrade their weapons and come looking for revenge, he pulls out the Dragon Subduing Mace, smashes their weapons in one blow, and scatters their ashes to the winds.

Yet he still has no idea how many people want to kill him, and spends all day complaining that he has no enemies. Of course he doesn't. His enemies don't last three days! As if he'd have any!
