Putting down the slip for [Seven Star Springs] Di Tou couldn't help but feel his head hurt again. The technique was pretty much as the clerk had explained, but much more difficult to use in actual combat. To be honest, Di Tou wasn't even sure if he'd be able to use it out of combat, it just seemed like too much information to process.
This could be seen even through investigating the jade slip. The contents inside… had already surpassed the length of a cultivation manual, much less an ordinary technique slip. And worst of all…
Looking down at the several sheets of crumpled paper on the ground, and the page on top that was filled with complicated symbols, Di Tou couldn't help but feel a complicated expression. Trigonometry and calculus, his two good friends had come all the way to the world of cultivation to reunite with him, how kind, how dedicated, how f*cking foul.
