Cleaned a little.

Eryi held the heavy heavenly book and retracted his upper bunk, muttering and complaining that this broken book was so heavy.

Although I felt very tired, after eating and replenishing, I took a bath and relaxed, which slightly restored Eryi's spirit.

So even though I felt that waves of tiredness kept coming, I still forced myself to open the Book of Heaven.

Because the [reading technique] imprint in my mind disappeared again.

Eryi, who felt something, read the description of [Reading Technique] in the Book of Heaven, and found that it was indeed upgraded!

Eryi thoughtfully, he turned out paper and pen from the head of the bed.

Start recording some changes you feel during use.

First of all, the upgrade rule of "native book ability" of [reading technique].

In his impression, the [Reading Technique] of Level 0 is about 6 seconds each time it activates the technique, and the successful activation effect will last for 10 minutes.

He used it for about 10 consecutive times, which was more than an hour, which led to the upgrade of the [Reading Technique]!

However, the [Reading Technique] at level 0 and 1 is slightly shorter than the time required to activate the Technique.

It is estimated that it will take about 5 seconds, and the successful activation effect will last for 20 minutes, and the reading speed will also double.

He used it about 20 times and took more than six hours to upgrade the [Reading Technique].

According to this rule, that is, the activation time of level 0 and level 2 [reading technique] will be shortened to 4 seconds? Will the upgrade require 30 activations?

According to each activation, the reading effect will last for 30 minutes. It takes a total of 900 minutes, which is 15 hours to upgrade again.

21 feels that if I am in a state of concentration in [reading techniques].

It is not difficult to study continuously for 15 hours, but what bothers him is that using the "Tian Shu Ability" seems to require some consumption.

Originally, he thought that what he had consumed was "mental power".

The legendary magician consumes that thing when using magic?

Since the "Heavenly Book Ability" is so similar to some kind of magic skill, then he is activating the [Reading Technique] technique.

It is reasonable to use up some of its own mental power when it creates a magical "reading effect", right?

But the question is, why does using the "Heavenly Book Power" still cause a strong sense of hunger?

This is obviously a symptom that occurs after a lot of physical energy is consumed, right?

Eryi, who could not find the answer, shook his head in confusion.

Staring at the level 2 [Reading Technique] technique on the Heavenly Book, I re-imprinted it into my mind.

But as soon as I was successfully imprinted, I couldn't help it and felt dizzy.

My eyes turned dark and I finally recovered a little, and I became depressed again.

"What's going on?"

The brain is tickle and the scalp is numb.

I could clearly feel that I seemed to have become weaker again, and I couldn't help but be shocked!

I lay dizzy on the bed and rested for a while.

Eryi recovered and couldn't help but feel scared.

Through the state of feedback, Eryi can probably guess that whether it is using the ability of the Heavenly Book or the branding technique, it may require some "energy" of one's own.

Moreover, the "energy" consumed by the branding technique is probably much higher than the ability to use the Heavenly Book!

No matter whether this energy originates from the human body is spiritual energy or physical energy, as long as you use the ability of the Heavenly Book, you will inevitably pay the corresponding price!

Considering the ability to use the Heavenly Book, it will consume both "spirit" and "physical strength".

21 decided to not understand the principle of this.

This consumed "life energy" is called "energy".

And after a day of study.

He consumes a lot of "spiritual" and "physical strength".

Therefore, at this moment, my "life energy" should be already in a "weak" state, so naturally I can no longer overdraw.

If the biological energy such as "life energy" is seriously overdrawn, what side effects will it cause to the human body?

Eryi is not very clear, but he also knows that it will definitely not be a good thing.

So I quickly closed the pages and continued to study the heavenly books without daring to death. I prepared to take a good rest before talking.

But just after he closed the cover, he accidentally discovered that the crystal stones on the cover of the Heavenly Book seemed to have become dim again.

“Huh?”

21 had already vaguely noticed it before.

There should have been some mysterious connection between myself and the Heavenly Book.

I clearly remember that when he got up in the morning, the crystal stone seemed to be nourished by a certain amount of nourishment after absorbing a lot of his "energy", thus restoring some luster.

But now, as he exhausted his "energy" in his body.

This crystal stone has actually been restored again, with its gray appearance!

"Is the luster of this crystal connected to my mental state?"

Eryi was very surprised and suddenly remembered that he was given the ability of [identification] by the Book of Heaven. He couldn't help but hesitate for a moment.

Although the branding technique can no longer be used, the ability to use the Heavenly Book consumes much less energy than the branding.

Eryi felt that although I was very tired at this moment, I felt like I was having a night out with my roommate all night.

But it was just a lack of energy, and it was not enough to fall asleep by closing your eyes, so it shouldn't be able to reach its limit.

Plus, the lucky thing is that it consumes little ability to use the Heavenly Book.

I really couldn't bear the curiosity and decided to take a risk and give it a try.

Otherwise, he would always be troubled by all kinds of doubts and his mind was full of various associations and problems, and he would not be able to sleep even if he wanted to.

Eryi took a breath, adjusted the angle on the bed, placed the pillow behind him, and leaned himself against the head of the bed.

To prevent him from fainting after a while, and accidentally turning off the bed... He slept on the second floor!

After he was ready, Eryi held up the heavy heavenly book with both hands and looked at the crystal on the cover.

But his eyes were sore, and no "identification information" appeared in his mind.

[Identification] Is it invalid?

Or is [Identification] ineffective for this heavenly book?

I felt my state, and it seemed that there was no change. I looked around and looked around.

I started staring at the LED small bed light sandwiched on the bed frame, and an identification information immediately emerged in my mind:
Chapter completed!
