Maxed out leveling , i have read it before. It was very awesome manhwa. 

Type:- Dungeon, hunter, Very strong mc, good character development

Mc is very strong and her sister is a little sister(20+) is a high ranking hunter.

Summary:- 14 years ago, when mc family was getting back from the amusement park the car accident happened and both parents died. His brother at the exact same moment was transported to murim world. Now the dungeon started appearing in the world at the exact moment in the world. Her sister grow up on her own and became a strong(not high ranker) hunter. ........ Now about his brother, he lived in the murim world and came to known as supreme sword emperor. He was menace and the strongest in the murim world. His hobby was killing bad people ruthlessly. After 140(one hundred fourty)years he was finally able to return to earth and found out only 14 years have passed. He then joined as hunter and made her sister a high ranker hunter........

Overall, its a action-menace MC-good siblings manhwa.
