A little bit of cleaning.

Holding the heavy book of heaven, Eryi retracted his upper bunk, muttering and complaining that this broken book was really heavy.

Although I felt very tired, after eating and supplementing, I took a shower to relax, which made Eryi's spirit recover a little.

So even if I felt that a wave of tiredness kept coming, I still opened the book of heaven with strong spirits.

The [reading] imprint in my mind disappeared again.

The second one, who felt something, looked at the book in the sky, and there was a description of [reading technique], and found that it had really been upgraded again!

Er Yi thoughtfully pulled out a pen and paper from the bedside.

Start taking notes on some of the changes you feel during your use.

The first is the escalation law of the "Heavenly Book Ability" of [Reading Technique].

He had the impression that the time required to activate the technique each time was about 6 seconds, and the effect lasted for 10 minutes after the activation was successful.

He used it about 10 times in a row, which was more than an hour, and it led to the upgrade of the [Reading Technique]'s technique!

However, for the Level 0 Level 1 [Reading Technique], the time required to activate the technique each time was slightly shortened.

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

He used it about 20 times, and it took him more than six hours to level up [Reading].

According to this rule, that is to say, the activation time of the [Reading Technique] at level 0 and level 2 will be shortened to 4 seconds, and it will take 30 times to level up?

Based on the fact that the reading effect will last for 30 minutes per activation, it will take him a total of 900 minutes, or 15 hours, to level up again.

The second one felt that if he was in a state of concentration [reading].

It wasn't difficult to study for 15 hours in a row, but what bothered him was that using the "Heavenly Book Ability" seemed to require something to consume.

Originally, he thought that what was consumed was "spiritual power".

Isn't that what the legendary magician uses magic to consume?

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

When it produces a magical "reading effect", it consumes some of its own mental power, isn't it?

But the question is, why does using the "Heavenly Book Ability" still produce a strong hunger pang?

This is obviously a symptom that only appears after a lot of physical exertion, right?

Er Yi, who couldn't find the answer, shook his head in confusion.

Staring at the Level 2 [Reading Technique] technique on the Heavenly Book, he re-imprinted it into his mind.

But as soon as the brand was successful, Er Yi couldn't help it, and he was dizzy for a while.

His eyes were black for a while, and he finally recovered some of his spirits, and he languished again.

"What's going on?"

The brain is wooden, and the scalp is numb.

I can clearly feel that I seem to be getting weaker again, and I can't help but be surprised!

Dizzy, I lay on the bed and rested for a while.

Only then did the second one recover again, and he couldn't help but be afraid for a while.

Through the state of his own feedback, Eryi can probably guess that whether it is using the Heavenly Book ability or the branding technique, it may need to consume some kind of "energy" of its own.

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

Regardless of whether this kind of energy from the human body is spiritual energy or physical energy, in short, as long as you use the ability of the Book of Heaven, you will inevitably pay the corresponding price!

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

Two One decided to figure out how this works.

This kind of "life energy" that is consumed is called "energy".

And after a day of studying.

He consumes a lot of both "mental" and "physical".

Therefore, at this moment, one's own "life energy" should be already in a state of "weakness", and naturally it can no longer be overdrawn.

If the bioenergy of "life energy" is seriously overdrawn, what side effects will it cause to the human body?

I don't know very well, but I also know that it will definitely not be a good thing.

So I hurriedly closed the page, and I didn't dare to continue studying the book of heaven anymore, and I was ready to take a rest.

But after he closed the cover, he inadvertently found that the spar on the cover of the Book of Heaven seemed to have become dim again.

"Huh?"

The second one had been vaguely aware of it long ago.

There should have been some kind of mysterious connection between himself and the Book of Heaven, which originated from the spiritual level.

I clearly remember that when he got up in the morning, this spar seemed to have received a certain amount of nourishment after absorbing a lot of his "energy", thus regaining some luster.

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

This hedron has actually recovered again, and it looks gray!

"Could it be that the luster of this spar is linked to my mental state?"

Er Yi was very surprised, and suddenly remembered that he was also given a [identification] ability by the Book of Heaven, and he couldn't help but hesitate.

Although the imprinting technique can no longer be used, the consumption of "energy" by using the Heavenly Book ability is much smaller than that of imprinting.

Eryi felt that although he was very tired at this moment, it was like the feeling of having been working all night with his roommate.

But it's just that I don't have enough energy, and I haven't fallen asleep with my eyes closed, so I don't think it's reached the limit yet.

Plus the fluke that uses the ability of the Book of Heaven consumes a small amount.

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

Otherwise, he is always troubled by all kinds of doubts, and his mind is full of all kinds of associations and questions, and he can't sleep even if he wants to.

Eryi took a breath, adjusted the angle on the bed, put the pillow behind his back, and leaned against the head of the bed.

Prevent you from fainting and accidentally falling out of bed...... He slept on the second floor!

After getting ready, Eryi picked up the heavy book of heaven in both hands and looked intently at the spar on the cover.

But his eyes were sour, and he didn't see any "identification information" in his mind.

[Identification] failed?

Or is it that [identification] is not effective at all against this heavenly book?

Feeling his state, it didn't seem to have changed much, and he looked left and right.

I started staring at the LED bedlight clipped to the bed frame, and a piece of identification immediately came to mind:

Unknown Alchemical Product: A resin-like material, composed of trace amounts of metal, glass, and extremely weak electrical elemental fluctuations......
