Luckily, Jia Xiu had read some of the Tentacle Monster's mathematical research while relaxing before, so he could recognize what the formulas in this material on demonic self-healing were.
Reading mathematical research to relax did sound pretty deranged.
Jia Xiu himself thought it was pretty deranged too.
But it really was a good way to reset himself. When the task at hand hit an obstacle he could not solve for the moment and left him frustrated, he could take a break or do something else.
Jia Xiu chose to switch among all his current research projects. When reading Mana Strings papers gave him a headache, he would look at the legacy left behind by the Tentacle Monster; when he got tired of that, he would study demonic knowledge again.
After making the rounds, he would find those papers looking rather pleasant again.
This method was useful not only for studying and research, but also for physical training and even getting stuck in games.
He used to switch to an English test paper for relief whenever he could no longer work through math or physics problems.
As for why he read the mathematical material left behind by the Tentacle Monster—
Jia Xiu's reasoning was simple. First, mathematics did not have cultural differences. Every race's mathematics was essentially a formal science for studying the world, a tool largely unaffected by culture, emotion, or lifestyle.
For example, Jia Xiu could not understand the Tentacle Monster's literature at all. Mathematics was difficult to understand too, but at least he could understand it.
Furthermore, since mathematics was a necessary foundation for technological progress and magical development, understanding a race's mathematical level could roughly reflect its technological and magical level—or, more precisely, its theoretical level in those fields.
As for practical application, based on what they
