I'll be glad to help you. I am sure you already know, we have two new sections---->
Manhwa and its subsection
The Breaker.
The Breaker has elements of Action, Adventure, Comedy, Drama, and Martial Arts. Its a Seinen series having two parts. Part 1 was called The Breaker and had 72 chapters. Part 2 is called The Breaker : New Waves and its ongoing with 25 chapters. Its one of my favorite series. I recommended Ghostie to read another manhwa Veritas (on hiatus sadly) as well.
Cutting it short, if you like action series, trust me you will not be disappointed.
