It had been almost 4 weeks since they left Uladia, and throughout the last three weeks, Silas had been trying to prepare himself for the torture he would endure when reaching the Darkless main base.
After his conversation with Archie, Silas understood that he had to get stronger much faster.
After a not-so-long internal battle with himself, Silas finally concluded that the only way to get stronger at the desired rate was by breaking, tearing, and repeatedly destroying every bone, muscle, and organ in his body.
It was the extreme version of going to the gym, and even though he had steeled most of his nerves by that point, he chose to put it off until they actually reached the base.
Healing a shattered limb took two to three minutes, and if they happened to be attacked by some kind of monster beyond their strength, Silas wanted to at least have the strength to run away.
