Arriving in front of the bookshelf, Xu Yan absorbed the Modification Value while checking the name of each book to determine if the book would be useful to him.
To Xu Yan's surprise, after checking a few books, he came across a book that Xu Yan wanted to read.
"Gravity Training Technique"
Finally, he found a book related to gravity!
Xu Yan opened the glass panel, took out the book, and began to flip through it.
On the first page was the name of the author, Elijah Bhutto.
Xu Yan tried to recall the name in his mind, but he did not have any impression of this person.
He flipped through the table of contents and began to read the main text.
This book talked about using gravity to train one's body, thereby obtaining a stronger body!
If one wanted a stronger body, they had to constantly train.
However, the human body was fragile. Directly carrying out weight training through gravity for a long time would cause irreversible damage to the body!
If it was more serious, it might even cause disability!
Therefore, Elijah Bhutto wanted to find a way to train the body in a gentler and more suitable way.
Therefore, after some research, he developed this Gravity Training Technique.
This training technique, through a large number of experiments and comparisons, was used to obtain the tolerance of different parts of the human body to different degrees of gravity, and thus adjust the strength of gravity for different parts.
In the end, he obtained a gravity arrangement for the human body's tolerance. It allowed every part of the body to receive the most suitable gravity for training, but it would not cause any damage to that part.
Using this method to train, the strength of the body would increase rapidly until it reached the limit of the human body!
Closing the book, Xu Yan understood Elijah Bhutto's idea. The Gravity Training Technique appeared on the interface.
Xu Yan raised the Gravity Training Technique to perfection and then used it.
Xu Yan felt the gravity he emitted split up, and at the same time, it turned into different strengths and dispersed to every part of his body.
After the Gravity Training Technique took effect, Xu Yan felt that every part of his body felt a little heavy, as if something was evenly pressing down on his body.
However, this weight was not very strong, so there was a situation where his body could not withstand this gravity.
This gravity was just right, not too much, not too little. It could train the body, but it would not cause any burden to the body, and it would not affect daily activities.
However, even though this training method allowed every part of the body to receive the appropriate amount of pressure, the human body was still too fragile.
Therefore, for every hour of training, he had to stop and let his body relax for two hours.
If he didn't do that, his body wouldn't be able to withstand the pressure for such a long time, causing the cells in his body to overload and burst.
Xu Yan tried it and found that it was true. After using the training method for an hour, Xu Yan felt that the cells in his body could not bear it anymore.
This was because the cells oversupplied the body with energy, causing the cells to become somewhat exhausted.
Elia Bhutto had mentioned this in his book. This was because the rate of energy output from the cells was not constant. Instead, as time passed, the rate of energy output would gradually decrease.
The reason for this was that cells could also be fatigued. The energy output rate of a full cell and a fatigued cell was definitely different.
Elijah Bhutto could not solve this problem either. He could only train for an hour and rest for two hours to avoid excessive cell fatigue.
However, Xu Yan had an idea. His current body was only that of an ordinary human's, and he could not continue training.
What if he used this training method on his main body?
After all, his main body was an immortal body!
Not only were his cells much stronger than those of ordinary people, they could also absorb spiritual opportunity to repair their own fatigue!
Wouldn't he be able to continue training like this?!
However, it was a pity that his main body was hidden in the depths of his soul, and there was no way for him to train in the gravitational force training method.
It seemed that he could only try this idea when he returned.
Xu Yan looked at the time. It was already one in the afternoon. No wonder he was hungry.
The weakness of this world's superpower system was too obvious. Whether it was the Meteor rank or the highest Breaking Dawn rank, they all needed to eat on time every day to maintain their physical strength.
This weakness was unbearable. His spiritual force was already strong enough to destroy the heavens and earth, but he still needed to eat to replenish his physical strength!
Xu Yan could not help but wonder if there had ever been a Breaking Dawn rank who had accidentally been trapped in a remote place and starved to death!
Arriving at the school cafeteria, Xu Yan ordered a portion of sweet and sour pork tenderloin and tomato scrambled eggs.
This was Xu Yan's favorite dish. It was delicious and went well with rice!
After eating, Xu Yan returned to the ninth floor of the library and continued to absorb the modification points of the ancient books.
He had already absorbed quite a bit of the modification points of the ancient books on the ninth floor in the morning, and estimated that he would be able to finish absorbing them in less than two hours in the afternoon.
Xu Yan absorbed the modification points while looking for books that were useful to him.
However, it was a pity that even after two hours, Xu Yan had finished absorbing all the modification points of the ancient books on the ninth floor, he still did not find a book that was useful to him like the 'Gravitational Force Training Method'.
It seemed that he could only wait until he followed Austin to the kingdom's library tomorrow to see if there were any books that could be useful to him.
Xu Yan looked at the time. It was only three in the afternoon, and there was still plenty of time.
Thus, Xu Yan left the ancient books section and began to look for other books on the ninth floor.
Although there was nothing useful to him in the ancient books, it did not mean that there was nothing that he wanted in the new books.
Moreover, new books represented newly created or discovered things. The probability of there being a book that was useful to Xu Yan was higher than the ancient books!
Unfortunately, new books did not have modification points, and it was not cost-effective to spend time here.
However, Xu Yan's modification points had already reached more than 15 million, which was enough for Xu Yan to use for the time being!
Moreover, now that he had finished absorbing the ancient books, Xu Yan could only go to the kingdom's library tomorrow. He had nothing to do in the afternoon, so he could take a look at the new books.
The new books on the ninth floor of the library were of the highest level in each field. Xu Yan could not understand most of them, so he could only choose books that explained the principles in simple terms.
However, even so, Xu Yan still benefited greatly. After all, this represented the highest level of human research on superpowers in this world!
Unknowingly, it was already evening. Xu Yan closed the book in his hand, "Speculation on the Origin of Superpowers".
This book was very interesting. It took a different approach to explain why humans awakened superpowers, and why everyone's superpowers were different.
This book believed that the reason why humans awakened superpowers after gaining Spirit Power was because of the different nature of each person's soul.
