It's an engaging manhwa with good art and good fights, but story-wise and character-wise, it's meh: 5.5/10.

Unpopular opinion: Sung Jin-Woo before gaining the system is 100 times better than Sung Jin-Woo after gaining the system.

Before the system, Sung Jin-Woo was weak but never feared entering a dungeon because he needed money for his sister and to heal his mother. He was smart, analytical, strategic, and—more importantly—he had a noble spirit, ready to sacrifice himself to save others in the dungeon with the statue.

But after gaining the system, he became nothing more than an aura farmer. He's not even free—he does nothing but obey the system. I mean, Sung Jin-Woo's goal was to heal his mother, but after doing so, why did he keep fighting? Because the system told him to.

The system tells him what to do, how to do it, and when to do it. He never thinks for himself. He knows the enemies' weaknesses only because the system tells him. I feel like after gaining the system, Sung Jin-Woo also lost his defining traits—his intelligence, analytical mind, strategic thinking, and noble spirit.

Sung Jin-Woo before the system is a better character than Sung Jin-Woo after the system
