A high-ranking officer in the Marines and a master of both Western and Chinese medicine, Feng Yu Heng is transmigrated with a duang sound to the Da Shun Dynasty.

His name was Brayden Neal, and he was an ordinary citizen. At eighteen years old, he was bestowed the title of a king!

After ten years of fighting in the northern borders outside the kingdom, he finally returned home. He swore to kill three people the moment he arrived at the capital…

Calling the old god’s mage, the knight who inherits the bloodline, looking forward to the glory of yesterday;

The noise of steam engines and the roar of cannons indicate the direction of the future;

In the ashes of the old world…he shall be crowned king!
