Silent Kingdom: Blood Sea Dragon

Don’t ask if the bonfire should be burning, first ask if the cold and darkness are still there.
Don’t ask whether the bullet should be loaded, first ask whether oppression and exploitation are still there.
Don’t ask whether there will be a future for the cause of justice. First, ask whether the injustice in the world is still there.

Mr. Yang was admitted as a rookie general by the ‘Justice Heaven’ just after graduating from high school.
This is an extremely glorious job. He will randomly travel to different worlds to punish rape, eradicate evil, and uphold justice.
This is also an extremely dangerous job, but fortunately he has a "sideline" plug-in.
