After playing with Daqing for a while, Er Yi found that he couldn't sleep anymore.

But today happens to be the time when Eryi regularly gives his brain a "holiday".

As a result, the soul energy and spiritual energy that were poured in in a large amount made me "insomnia", not to mention, and there was a vague feeling that the biological clock had been disrupted.

After this period of frenzied study, Eryi also found some shortcomings in learning ability.

Although with the improvement of his intelligence and physical attributes, high-intensity learning can no longer cause too much burden on his brain and body.

But this does not mean that he can absorb knowledge without scruples, sleeplessly and frantically.

To put it simply, when his brain is learning, it is like a high-speed computer, although it can store a large amount of information, but it will run slower and slower with a long period of operation.

This will lead to a decrease in his learning efficiency and comprehension ability, and will also inexplicably produce a kind of boredom and rejection.

Eryi himself probably knows that this phenomenon should be caused by psychological exhaustion.

Enter the [Mind Space] in a [Meditation] state and study using the time difference caused by the passage of time seventeen times.

Although it can replace sleep to a certain extent, effectively reducing the study load and pressure on the body, it can also cause him a serious sense of time confusion.

To others, he just slept eight hours a night.

But in fact, he felt like he had been attending classes 24 hours a day for a week without a break at all.

Although the pleasure of absorbing knowledge can largely eliminate the psychological pressure of this ultra-high-intensity learning process, the accumulated knowledge reserve is like a background program that constantly occupies the memory of the computer.

So Eryi had to give himself a vacation every 10 days.

So that the brain, which is always in a state of high-speed operation, can have a chance to take a break.

Selectively forget some useless information absorbed in the learning process, and sort out the knowledge that is not used for the time being, and store it in the brain library for later use.

This is like using the "one-click acceleration" of management software to clean up the occupied "memory" for the brain computer.

If this is not the case, Er Yi is very suspicious that he will have serious psychological problems sooner or later, just like those demons who really suffer from "genius disease".

After being promoted, because of the great improvement of intelligence attributes, Eryi found that although the speed of absorbing knowledge has become faster, the speed of strength growth has slowed down!

For example, if he is promoted from the apprenticeship stage of [Tier 0 Level 0] to the official caster class of [Tier 1 Level 0], he needs to absorb 100 million additional soul energy to burn and transform into a maximum of 1 million soul energy.

Then upgrading from [Tier 1 Level 0] to [Tier 1 Tier 1] may require an additional 100 million soul energy, and the proportion of burning transformation has also increased!

Because after the extra soul energy he absorbed was burned and transformed, the increase was still [Tier 0 Soul Energy], that is, it continued to accumulate on the basis of the original upper limit of soul energy!

But Eryi found that this would not allow him to continue to improve his "soul energy level", and if he wanted to go further, he would even need to burn and transform [Tier 0 Soul Energy] into [Tier 1 Soul Energy] again, and the ratio was still 100:1.

Eryi himself calculated the increase ratio of his "soul energy level" during the 0th level period, and listed a rough "upgrade experience table":

[Tier 0 → Tier 1]: 1,000,000 Soul Energy / 100,000,000 Extra Soul Energy

Level 0← [100]→ Level 1← [100]→ Level 2← [200]→ Level 3← [300]→ Level 4;

......

Level 17← [25.84]→ Level 18← [41.81]→ Level 19← [67.65]→ Level 20;

Last: [Level 0 Level 20]← 100→ [Level 1 Level 0];

Calculated in this way, in fact, the "experience points" he accumulated at level 0, that is, the total amount of soul energy, was not the imaginary 1 million, but 2.771 million, and the extra soul energy burned and transformed in the process totaled 277.1 million!

If it weren't for the coincidence, he opened the six "soul energy warehouses" that can provide a steady stream of soul energy, and if he only relies on his own accumulation, I'm afraid that he will only be able to advance in the Year of the Monkey!

And after being promoted to [Tier 1 Level 0], the starting point is 1 million Tier 1 Soul Energy quota before it can be promoted to [Tier 1 Tier 1]!

And these 1 million 1-order soul energy needs to burn 100 million 000 order soul energy, which is converted into 10 billion additional soul energy!

At that time, when this "upgrade experience table" was calculated, the second one almost didn't explode!

He is now absorbing through his own live broadcast, plus the six of them who plundered the Shrimp Emperor, and can earn an average of 100 million Rank 0 extra soul energy per day!

Press 100:1 refining to get 1,000,000 Tier 0 Soul Energy, and then press 100:1 Refining to get 10,000,000 Tier 1 Soul Energy.

In other words, if he wants to reach [Tier 1 Tier 1], it will take him 100 days to accumulate 10 billion extra soul energy, and this is just the beginning!

This gave Two One a very bad premonition!

Because a simple calculation can be known, assuming that he can't increase the total amount of extra soul energy he can absorb every day in the future:

Level 0← [100 days]→ Level 1← [100 days]→ Level 2← [200 days]→Level 3...... Question: How many days does it take for him to reach Tier 2?

Of course, it doesn't seem to have any effect if he doesn't improve, anyway, the extra soul energy he absorbs every day will be burned and converted into the upper limit of soul energy, which will accumulate in the 0-level soul energy pool, and it will not affect his use.

But this also made him understand why the spells he mastered could only be upgraded to [Level 0 and Level 9], instead of further breaking through to [Level 1] as his rank increased!

Because he doesn't have a first-order soul ability!

Without the gravitational force generated by the 1st order soul energy, the 1st order arcane energy cannot be gathered!

And whether it is released with soul energy or arcane energy, he can't use a Tier 1 spell!

The only exception to this is the spell [Loot Soul Crystal], as it can consume Tier 0 Soul Energy to loot Tier 0 Soul Crystals!

This made Er Yi hesitate for a long time, is it to pursue the "quantity" of soul energy, or the "quality" of soul energy?

If he didn't guess wrong, as his own strength grew, the level of the spells that the Book of Heaven would activate for him would also increase, so would he use it or not?

As soon as he thought of this, Eryi couldn't help but have a headache, but fortunately, it didn't seem to have much impact temporarily

He could only put this question aside for the time being, checked his attributes, and found that in addition to soul energy and arcane energy, he had another spiritual energy attribute!

This is obviously the psionic energy drawn from the artifacts he has restored.

It's a pity that even the ones he repaired himself, plus those repaired by Senior Sister Li Li, there are not 100 utensils in total.

Although the spiritual energy contained in these cultural relics pottery itself is huge, the absorption speed is outrageously slow, and the energy supply speed that different pottery can provide is not the same, and I don't know what the law is.

The spiritual energy he absorbed was stored in the spiritual core condensed in his heart, and he had not found any use for the time being.

Inadvertently seeing the spirit body floating around him, he had a whim, spiritual energy, spirit body, all with a spirit word, since the spirit body can absorb soul energy, can they absorb spiritual energy?

However, after taking a look at the 2,328 points of spiritual energy he had absorbed at the end of the day, Er Yi decisively gave up the idea of trying it.

He couldn't directly infuse the spirit with spiritual energy, and if he wanted to test whether the spirit could absorb the spiritual energy, he had to condense at least a spirit crystal.

Although I don't know how much spiritual energy is needed to condense a spirit crystal, but when I think of a 0-order soul crystal, it contains tens of millions of additional soul energy, even if the spirit crystal is not higher than it, it is estimated that it will not be much less than it, and it can only be enough in the year of the monkey?

Shaking his head, Eryi shook off his unrealistic thoughts and shifted his attention to the purple spirits floating around.

He was surprised to find that the number of spirits seemed to be starting to become scarce, and the rest were mainly first-order spirits that were difficult to grasp, and the blood-colored spirits that were only lying by his side.

Er Yi scratched his chin, flipped his hand and took out a soul crystal, and leaned over to a purple spirit floating by......
