Joint training

That morning passed quickly, so quickly that afternoon arrived and the sun was still up while Strax lay on the sofa, still recovering from the aftermath of his fight with Beatrice the previous night.

"I wonder how many times it will take to level up..." Strax murmured to himself, trying to find a way to understand Dual Cultivation. "Anyway, any excessive activity can cause problems in the future. I'm not indestructible, and this isn't like the novels I used to read where the protagonist has infinite stamina to keep going endlessly." He thought, many things crossing his mind, but he didn't want to rely on dual cultivation; that was his main stance.

"I'll continue cultivating through meditation as I always have. Using dual cultivation will be only for very specific moments. I still don't know the purpose of the System or how it was given to me, but I can't rely solely on this tool. I need to become strong on my own, not as a tool of the system."
