"Actually, you don't need to worry. It's pretty fast to level up the first few layers of Inner Strength. An ordinary person can reach level six or seven in about ten or fifteen days. If you practice like crazy, a week should be just about enough."
"The levels later on slow down, so just take it slow. In the latter stages, you'll definitely obtain more powerful Inner Strength, and then you can just switch to another one."
Xiao Jie thought, 'Okay, Inner Strength levels six or seven in a week, I can accept that pace.' Duan Yu once said it takes three years to learn and ten years to practice. That had shocked him. If it really took him ten years to master it, it would indeed be deadly.
"What about this Saber Skill of mine? Do you have any advice on how to use it in combat?"
