Will Mark agree to marry Princess Shen Ling?

Both of them entered the treasury. Mark saw millions of gold coins spread around like sand with jewelry and gems found here and there. However, they didn't impress him a bit as he had more wealth at the moment.

The princess then reached a wall with a huge handprint on it as if it belongs to a giant. "This is our secret armory." She introduced it as she placed her right hand on the print.

The wall door slid to the left, revealing a chamber with weapons arranged on the walls.

There are about 110-120 of them and every single of them is a semi-divine/earth-grade weapon. 

As Mark inspected them, he found that several of them are actually in Ruby grade, which is like a high-quality semi-divine weapon.

Along with that, he spotted something else. There was a common factor in every single weapon.
