Back in his small building, Yan found that the two children were still boxing very seriously, but Xiao Xi was sitting on the stone bench next to him, supporting his arms with his hands in a daze.

Seeing Yan come back, she first blushed, and then ran up excitedly and shouted, "Childe, you're back..."

Yan looked her up and down, and his special eyes allowed him to ignore his appearance and directly observe the flow of qi and blood in Xiao Xi's body.

In six months, Xiao Xi's skin has exercised less than a third of her body...

Yan doesn't think that the cultivation of the physical realm, but only depends on the resources and the level of effort, and has nothing to do with talent at all.

Therefore, Xiaoxi has been lazy.

Yan thought for a while, and then said to Xiao Xi: "I am now a member of the Divine Power Realm, with a longevity of 240 years, with the improvement of the realm, this number will continue to expand, and your longevity is 120 years, if you don't cultivate seriously, you can imagine the consequences yourself..."

Xiao Xi's face turned pale, and then she retreated silently.

She understood what Yan meant.

Of course, Yan can understand the girl's mind, and he doesn't respond, not because he is cold-blooded, but because he is rational enough.

Just like a tribe is wiped out, he knows that people can't be resurrected after death, and grief and anger can't solve anything, so he doesn't do that kind of senseless sadness.

If he was really sad for a few months, would he still be able to kill Ying?

When he returned to the quiet room, he felt that Xiao Xi outside had already begun to practice boxing.

Yan smiled, he didn't like Xiao Xi to let him work hard, but he looked down on those who didn't work hard.

The people of your world have never known how envious Xu Yan, who was born on the earth, is to the people of this world.

And with such good conditions, I don't want to forge ahead...

After taking out a thick information book and a few pieces of jade, Yan began his study career.

What is two days enough?

Write a thesis, draw two pictures, eat chicken a few times, fall from diamond to bronze?

However, no matter how talented you are, it is impossible to learn a profound skill in two days.

However, Yan can!

The book was turned directly from beginning to end by him, Su Yu was pressed to his eyebrows, read it in an instant, and then two things were thrown to the ground by him.

He himself entered the hall of memory directly.

It's a vast space, with rows of bookshelves on which all the information that Yan Liangshi has seen and heard.

Everyone has the ability to remember, but most of this memory is recorded in the subconscious of the person, without hibernation, external stimulation and other special means, people simply cannot extract these memories independently.

But the Hall of Memory, under the effect of the Hitomi Technique, can do this.

At this time, a blank desk appeared in front of Yan, and he waved again, and the sky was full of symbols and words, filling the sky over the entire hall of memory.

These are the refining weapons, arithmetic, runes, and formation foundations he wants to come.

The time he had was two days, and if it was up to the backstage Blood Lotus challenge to begin, he would have a total of 46 hours left.

And forty-six hours in the outside world, converted into the memory hall, is 680 years!

The speed of sound is a basic unit, and the speed of light is much faster than the speed of sound, and what is faster than the speed of light is the human mind.

Pure human thinking is limited by the sluggish mechanism of the human body, and it is impossible to exert such an efficient speed, but thanks to the special space of the memory hall, Yan's memory hall is like the red lotus space, and there is a time difference of 1:129600 with the outside world.

Yan can learn 680 years of knowledge inside for two days outside!

Yan suddenly thought of the Baolian Lantern TV series he had watched before, Yang Jian created a thinking space and let Liu Agarwood read the book inside for ten years, Liu Agarwood read in it with gray hair and beard hanging to the ground, but outside, it was only for a moment.

Yang Jian also has a special eye, what is his name, the Eye of Heavenly Punishment?

After thinking about it for a while, Yan finally calmed down and began to study.

The foundation of refining is the easiest of the four courses, including three techniques: fire control techniques, object control techniques, and shaping techniques, and three sets of methods for controlling true qi.

As long as you have these three techniques, you can refine something, such as taking a piece of iron to practice an iron sword, a hoe and the like.

But this kind of refining is just a simple change in appearance, and it does not have much impact on the essential improvement of the artifact.

If you want to practice a set of advanced magic weapons, you must first learn the blending of various metals, in modern times, an alloy has to be tested countless times to be experimented, even if any metal is added by 0.1%, it will affect the overall performance of the metal after it comes out.

The magic weapons of the monk world are similar, they have special requirements for fire resistance, ice resistance and other elemental resistance, and they also have high requirements for the introduction of special attribute supernatural powers and true qi, from this aspect, the metal ratio of the monk world is much more complex than the alchemy on the earth.

And this kind of deployment, what needs to be used is arithmetic.

Yan originally thought that he had a foundation in earth arithmetic, and it should be much easier to learn the arithmetic here, but he was confused after seeing the arithmetic information.

The basis of arithmetic, to learn is a calculation method called the four-dimensional method of yin and yang hands, based on both hands, thinking as the guide, through the two instruments, three talents, five elements, ten directions and other hands-specific unique structure of the four decimal parallel space calculations, which is completely different from the mathematics of Yan Xue (can be Baidu Yin and Yang family arithmetic, this algorithm appeared in ancient China).

Yan Xue's mathematics is either in decimal, binary, or hexadecimal, and there is no way to use four bases at the same time.

But what you have to learn is that this is an algorithm, and after Yan studied it carefully, he found that this kind of algorithm seems to be quite reasonable, he has a set of strict and self-consistent logical structure, and the calculation speed is also very fast, in the case of proficiency, a monk can perform tens of millions of calculations per second, and if you use divine sense, this number of times may be tens of thousands.

Of course, this is an ideal situation, in fact, most people are not proficient at all, and ordinary monks come to learn this without even learning addition and subtraction in elementary school, and the progress of learning can be imagined.

Although Yan is also in contact with it for the first time, he at least has a foundation in calculus, multivariate equations, linear algebra and other mathematics, and at this time it is nothing more than one more field of study, which is not too difficult.

Yan thinks that this arithmetic is very useful even if it is placed on the earth, because this kind of arithmetic is four-dimensional parallel, it is quite easy to calculate the spatial structure, and it may be possible to solve a few mathematical conjectures with it.

It is said that the upgraded version of the four-dimensional method is the eight-dimensional method of gossip, Yan thought about the eight-dimensional method, and then looked at the four-dimensional method in front of him, and always felt that he really underestimated the group of monks here before.

Runes are an important part of the composition of supernatural powers, and the carving of runes on magic weapons is the basis for upgrading magic weapons to spiritual weapons.

The same piece of material, ordinary refiners make it a magic weapon, but those who are proficient in runes can practice it into a spiritual weapon, and the value has soared dozens of times, this is the gap.

There are a total of 80,000 rune foundations that Yan Yao learned, and these 80,000 runes constitute hundreds of magical powers commonly used on spiritual weapons through special combinations and spatial arrangements.

This should be the most difficult part for ordinary monks, 80,000 runes, he is not like Chinese characters, and it is interesting for you to remember.

These runes are a special kind of energy symbols, and most of them are ignorant to the monks.

And a large part of these symbols are particularly similar, such as 戌戍戊, a little crooked and a little shorter, the effect changes, maybe the original thing you designed was used to make a phone call, but you draw a little wrong rune, and the thing you made becomes a bomb.

But the most difficult part is simpler for Yan, just store them in the memory hall and take them as you go.

Things that need to be memorized, no matter how difficult it is to memorize, it is still rote memorization, but this kind of knowledge is completely indifferent to Yan, who has a hall of memory.

The best is the formation...

Refining tools and formations have always been brothers, after all, most of the formations are arranged with magic weapons, and large magic weapons are indispensable to arrange formations, such as the Sumeru ring to be arranged on the flying boat, the spirit gathering array, the wind fixing array, the suspension array and so on.

The basis of the formation is a set of spirit gathering arrays, small trapped arrays, small phantom arrays, small killing arrays, and small sealing arrays.

In this world, in addition to a few forms such as teleportation arrays, the rest are basically variants of these formations, that is, the materials used are upgraded, and the formations are more complex, but they are always changing.

After learning these five formations, you can arrange most of the formations in this world, it is nothing more than a matter of difficulty, but there will be no barriers to knowledge.

And if you can understand these five formations, you can invent the formation yourself, even if it is the Liangyi Dust Array, the Zhuxian Sword Array, the Zhou Tian Xingchen Great Array, the Ten Absolute Arrays, and the Twelve Heavenly God Evil Arrays, they can all be invented.

Well, as long as you're savvy enough.

Yan once thought that cultivation and supernatural powers were all there was to this world.

Unexpectedly, this world is much more exciting than he imagined!

If Yan originally studied just to participate in the Blood Lotus Challenge, now Yan's study is purely for knowledge...

Knowledge is the only kind of existence that can resist family lineage, bloodline, supernatural powers, and plug-ins.
