In the three realms, only for justice!
It seems to be the oath of a brave and fearless knight. In the vast three realms, he sticks to his belief in justice, does not give in to power, is not tempted by interests, and only aims to maintain fairness and kindness in the world.
The protagonist is about to embark on a journey full of difficulties and obstacles, and use the sword of justice to eliminate evil; or perhaps this is an inspiring slogan that encourages people to always uphold justice and make the right choices when facing various challenges in life.
