The Author's POV

Over the course of the next few days, I managed to get a good grasp of the book.

After experimenting with the book on every occasion I could get, I managed to decipher the main uses of the book.

First off, whenever I wanted to change something inside of the book, mana would be consumed.

Depending on what I changed, a different amount of mana was consumed to supplement the change I made.

For example, let's take the gravity room example.

I changed the gravity room setting from 2g to 4g. At that time approximately three-quarters of my mana was consumed by the book.

On the same day, after taking a cheap 50 U potion to replenish my mana, I tried again, but this time I changed the gravity setting from 4g to 3g.

The result was that half of my mana was consumed.

Thanks to this I was able to figure out that the change made in the book is proportional to mana consumption. Meaning that the bigger the change I made in the book the more mana I consumed.

To verify this I tried putting '6g', which I regret doing now, as I nearly passed out from having all the mana within my body get sucked out.

When I managed to regain some strength I found that my mana was completely drained. When I glanced at the book to see what changes it brought, I couldn't help but break out into cold sweat. Apparently, the MC broke one of his legs as a result of my meddling.

Quickly replenishing my mana using another cheap potion, I immediately reverted it back to 2g which I found to be the most optimal gravity setting for the MC.

The next thing I tried was 15g. I wanted to see what would happen if the change was well beyond my capabilities.

The result was that, exactly 5 seconds after I made a change, my change quickly reverted back to '2g' almost as if it never happened.

The next thing I found out about the book was that it was 10 minutes ahead of my current timeline. Meaning that it tells me the happenings of 10 minutes in the future.

Moreover, I found out that when the events that were in the book coincided with my timeline, I could no longer add any more changes to the book.

For example, 'Kevin exits the training room'.

When those words appear in the book, it actually means that Kevin will exit the training room 10 minutes from now.

So when Kevin actually exits the training room in real-time, I could no longer make any changes in the book. From this, I could infer that the book cannot change the past, but only change a possible future.

I was actually quite lucky that I had used potions to replenish my mana as I would've been in deep shit if the MC had injured himself on the first day.

The last thing I found out was that the book only gives me Kevin's perspective. This means that the book is actually kind of useless to me as I am not Kevin.

I wasn't particularly saddened by this fact as I could use this book to determine whether I could help Kevin without needing to expose myself.

Today marked the fourth day of me starting classes, and today is my first non-practical lesson since I had arrived here.

Since people usually come to the lock to develop their abilities, most of the lessons were based on real combat and body training, therefore making theoretical lessons quite rare.

'Molecular Anatomy'

This was the name of the theoretical lecture. An incredibly complex class that looks through the body of monsters and beasts.

Professor Theodore Rombhouse, a renowned researcher with lots of awards to his name, was the professor in charge of this class. He and his team were responsible for singlehandedly finding out the mystery as to why beasts went beserk after mana invaded the atmosphere.

Professor Rombhouse was a plump middle-aged man with curly white hair and a calm disposition. If it weren't for the fact that his eyes were currently transfixed on the huge creature laying on the table in front of the class, people would've easily mistaken him for your nice neighborhood uncle.

"As we can see, the wingspan of the berzerk pigeonette is around 1.8 meters, drastically different from their predecessor the pigeon which tended to be at around 70 cm in length. That is almost a 2.6 times increase in length!"

Excitedly yelled the professor as he caressed the gigantic creature on the table. You could hear from his voice that he was incredibly engrossed by the creature in front of him.

"After long conclusive research, we have managed to source out the reason for the pigeon's drastic growth. As all of you know, my team was responsible for finding out as to why beasts go berserk at the presence of mana."

Finally taking his eyes off the huge creature, Professor Rombhouse took a good look at the class and asked.

"Now can anyone tell me why humans manage to retain their sanity while animals can't?"

As this was common knowledge a lot of hands were raised. Since I wanted to blend in I also raised my hand without thinking much.
