Larcen looked at the base that was squeaky clean on the inside and let the people check if any monsters were hiding inside. While everyone was busy, Larcen deleted the blood imprint and blood core skills from his status.
He did not edit it and directly deleted it, which meant that the perks of the skill did not apply to him anymore. Looking at his stats that had gone back to normal, Larcen brought out a can filled with the blood of the elf he had slain and looked at it before adding the two blood skills back into his status.
As a merchant who got the skills from merchant skill chest, he could equip and unequip skills any time he wished as there was a limit to the number of skills a person could have. Others could delete their skills too but if they had to get it back like Larcen, they had no choice but to buy it from the trade terminal or receive it directly from Larcen himself.
