Weapon seller in the world of magic

After the sacrificial ceremony and praying to the ancestors is finished, Ouyang Zen returned to the palace but he didn't step inside. Instead, he went to the palace grounds and blessed the citizens with his presence as each of them was given 5 gold coins and a set of clothes.

This is the tradition of the Eastern Sun kingdom, going on since its foundation.

The nobles, court officials, royal knights, generals, and the members of the royal family will have to present the king with a birthday gift but the commoners and soldiers, on the other hand, will be receiving presents from the royal palace.

As millions of citizens would visit the capital city every year, the donations will start a week before the king's birthday and will end a week after the event. Those who missed the deadline or cannot show their identification documents won't be able to enjoy the rewards.
