Collapse of the Ladros City: Deal

A monster lord appeared all of a sudden. The worst was that it wasn't an ordinary monster lord. It was at the top tier in terms of fighting ability. The Underground King was at the level of the Destruction Queen. 

'That guy... I remember him causing a commotion on this continent a thousand years ago. I didn't know that he was sealed here. If he was sealed, maybe the other two were also sealed, but we have no idea where they are,' Saya said to him. She was also familiar with the Underground King and the other two kings as well.

'We don't need to worry about it for a while. That monster lord will take some time before it breaks the chains. Our problem right now is Randolf,' Souta replied to her with a gloomy expression. Although Randolf wasn't at the Red Crystal Empire's Emperor level, he was still out of his league.

The difference between his current strength and S-rank was too large.

Should he use his cards?
