I Awakened the Chivalrous Merit System

Yun'an traveled to another world, and in his first life he became a subjugated prince on his wedding day, and his fiancée was forced to flee to the end of the world. He jumped off the iceberg but lived a new life and awakened the warrior system. Unexpectedly, his system went dormant less than a week after it was turned on!!! Yun An: "The dog system is so unreliable!" Although Yun An was a little disappointed, he soon clenched his fists and secretly vowed that no matter what, he would not let the tragedy of national subjugation happen again!
