There was nothing much to this matter; it was only a trivial thing. But Shi Tiexin discovered that there was one fundamental difference between himself and the students here. That was, he could not skip layers while cultivating secret manuals.
Didn't understand?
This phenomenon was rather interesting when explained.
When students in this world learned knowledge, they were not entirely confined by the shackles of a manual's layers. Take Basic Physics, for example. In middle school, they could first study the contents of all four layers mixed together, then revisit them one by one and dig deeper in high school.
Even if they merely swallowed everything whole without chewing, it would not affect anything at all. Though the order in which knowledge was absorbed was divided according to difficulty, it was not necessarily so rigid.
Who said primary school students could not learn a little about space in advance? Hadn't there been many students in the primary school from Scholar Stone's memories who gestured wildly every day, performing cringeworthy bizarre moves while roaring things like "Two-Dimensional Space" and "Galaxy Starburst"?
But Shi Tiexin found that he could not.
More precisely, he could skip ahead and read. He could completely read through all of middle school Physics first; knowledge absorption itself was unrestricted. But this form of absorption would not increase the progress of his Heart Technique cultivation at all.
In other words, he had to first cultivate Basic Physics First Layer properly before he could begin practicing the second layer. If he had not even passed the first layer, then even if he learned the second layer so thoroughly that flowers rained from the sky, not a shred of mental energy would increase.
Of course, if he truly learned the second layer to the point where flowers rained from the
