Monarch of...

Nathan and Tristan were walking toward the stadium where the tournament was taking place.

"Ah! Do you have a Blood concealment potion?"

Tristan almost fell due to Nathan's remark.

Blood concealment potion would temporarily disguise your genetics. During this duration, even if your hair, blood, or any other bio-identification test is done on you, the result will be different from your original result.

Also, if your blood or hair is taken during the time the potion was active and tested later, the result would still be different.

Needless to say, the value of the potion was astronomical.

The only way to get one was either to ask high-ranking bloodline vampires or hope to get one from dungeons. 

Admittingly, Earth did not have vampires. Their only choice was dungeons.

"Yes" 

Tristan sighed. As usual, Mr. Pepe was waving around the name of such a precious potion openly without any worries.

"Give me one tomorrow, then."
