Caleb took a deep breath and decided in his heart. No matter what. This city is the place where his friends live. Andre, Luna, Clifford, Kidd, Kazuto, and that damned Rekka. Not to mention, Rozho took the effort to introduce him to his master and the old man helped him awaken his sword aura.
He wasn't the kind of ungrateful person. When someone did him a favor. He would pay them back double. Favor for favor and enmity to enmity. That was his motto in his first life as a killer. Not to mention, befriending or getting the favor of a Sword King is surely a win! Isn't it worth it?
The old man might even teach him a method to increase or make his comprehension of sword intent faster. Now, he was in the realm of Sword Disciple. The next realm was Swordsman and then Swordmaster.
