Lu Yun sat at the head of the bed, and it had been half an hour.

"Theoretically," Lu Yun touched his chin lightly: "The original owner of this body has caused serious damage to the brain and nervous system for some reason, and the bioelectric network has been destroyed by nearly two-thirds, and then repaired by some unknown energy, just at this time, my own bioelectric network appeared in his brain, replacing the destroyed part of the bioelectric network." So this is the rebirth of the novel? EMMMMM……”

crossed.

So, since you have crossed over, the first thing you have to face is the three questions of life.

Question 1: Who am I?

Before the crossing, Lu Yun was a nuclear engineering physicist.

Now that this body has been taken away by himself, according to the remaining memories in his head, it is still right to call Lu Yun.

Next is the physical condition.

Lu Yun looked at his hands first.

Each hand has five fingers: thumb, index finger, middle finger, ring finger, and little finger.

There are palm prints on the palms. Fingerprints on the fingertips.

Nine buckets.

Move your fingers without any discomfort and the synchronization rate is 100%.

shook his neck again, and then Lu Yun pressed the skin with his fingers, it was very soft, very Q-elastic, and it felt very good.

I took another look at the shape and joints of the arms and legs.

It's exactly the same as the humans on Earth.

Finally, Lu Yun got up and looked in the mirror and carefully observed his facial features.

Two eyebrows, two eyes, a nose, a mouth, two ears.

Black hair, black eyes.

He's a handsome guy.

Look at the age of about early 20.

After that, Lu Yun looked at the things in the room, took a line, and made a measuring tool - one meter seven or eight tall.

Finally, I pulled open my pants and took a look.

Big.

It was perfect.

The kind that makes sense.

"Eukaryotic domain, animal kingdom, metazoan subkingdom, posterior mouth animal phylum, chordate phylum, vertebrate subphylum, amniotic general, mammalian class, animal subclass, euzo subclass, primate, true primate, straight nose monkey suborder, ape suborder, narrow nose suborder, true narrow nose suborder, ape superfamily, hominidae, human subfamily, human subfamily, homini, homini, homo homo species."

Carbon-based organisms.

For the current state, Lu Yun is quite satisfied.

Then the second question comes up.

Where am I?

Lu Yun walked out of the room and came to the courtyard.

The sun was high in the sky, to his left.

There is only one.

The sunlight is harsh, and the whole is bright yellow.

OK.

Jumped a little, the gravity was normal, no discomfort.

The basic laws of physics are still there, and there is no big problem.

In other words, at least for now, the planet should belong to a stable star system.

What kind of galaxy it is is not yet known.

I hope it's not the three-body problem.

The current state is that he has just crossed over, and Lu Yun is still a little unable to distinguish between the southeast and the northwest, so for the time being, according to the laws of the earth, the east will rise, and it will be determined by observing it for a while, and it is not a big problem.

The temperature feels very good, it should be around 24 degrees.

The sky is cloudy, white, and the sky is blue.

This color basically means that the composition of the atmosphere should be close to that of the earth, and the presence of clouds indicates that there is water vapor, and it will rain, and the environment is suitable for human survival.

And then gradually look down.

There are many mountains around, of different sizes, heights, but the vegetation on the mountains is luxuriant, most of them are green, and occasionally some red and yellow dots are dotted among the vegetation, which should be flowers and plants.

Further down, you can see a lot of buildings in the mountains in the distance, pavilions and pavilions carved beams and painted buildings, and the overall style is very close to the ancient Chinese architecture on the earth.

Nearby, he was surrounded by buildings similar to the courtyard he was currently in, resembling a human village.

In other words, this is an ancient Chinese world.

Combined with the remaining information in my mind, this is an ancient Chinese civilization with Xiuzhen as the main direction of development.

And the name of the realm here is Feiyun Sect, which is a cultivation sect.

His location was the outer gate of the Feiyun Sect.

The Ninth Outer Disciple Village.

Sixth Street, Sixth Household.

Equivalent to a student dormitory.

Lu Yun continued to observe.

He rubbed his foot lightly against the bluestone slab in the yard, and it was very lubricated to the touch.

This kind of large stone slab of more than ten square meters is difficult to get even with the technology of the earth, and Lu Yun feels that how this thing is made still needs to be studied.

"You, I, Him ......"

I casually tested the phonetic system according to the residual information in my head, and it was Chinese.

Communication is not a problem, and that's a good thing.

Then the third question comes.

What am I going to do.

Lu Yun began to think carefully.

There was not much information left in the original owner's brain, and after Lu Yun sifted it, he summed up a very important piece of information.

There are still seven days to go, which is the day of the spiritual power test of the outer disciples of the Feiyun Sect.

The requirement is to officially reach the realm of cultivating the first level of qi refining.

If you pass, you will enter the inner gate and become a formal disciple, and if you fail, you will be beaten back to the world, and there is no hope of cultivating the truth for a lifetime.

And the current state of this body is......

It's basically zero.

"I don't know what the situation of the original owner of this body is," Lu Yun touched his chin: "It seems that I have been cultivating for three years, and I don't feel any qi at all." I can't say no, since I inherited this body, I have to work hard, or I will be sent home as soon as I come - I don't even know where my home is...... Hiss! ”

Thinking of this, Lu Yun gasped!

As a native of China, a rabbit that is red from head to toe will be particularly insecure once he finds that his firepower is insufficient.

Especially when he was alone and traveled to a world of cultivation.

Unaccompanied.

I don't even know where my home is.

There's no way back!

"There are still seven days, which is a bit short!" Lu Yun's scalp was numb.

He began to think carefully about how he could officially enter the Qi refining stage in seven days.

I only have a full set of exercises in my head.

It includes but is not limited to the diagram of the meridian acupuncture points of the whole body, the knowledge of the Qi refining realm, and how to step into the basic knowledge of Qi refining.

However, this is of no avail.

Seven days to enter the Qi Refining from Zero, this is an impossible task.

Unless there is a cheat.

Do you have one?

Lu Yun began to touch his chin again, and then closed his eyes.

His advantage is that he has a very high-end and comprehensive knowledge of earth languages, mathematics, physics, chemistry, biology, geography and so on.

After all, he is a graduate student in nuclear engineering at the National University of Defense Technology.

The legendary god of learning!

If he was given the right materials, he could even make an improvised atomic bomb right now.

These could all be regarded as his golden fingers, but they could not help him enter the Qi Refining Realm within seven days.

What to do?

"Steady, don't panic!" Lu Yun narrowed his eyes slightly, thought about it carefully, and then came to a very definite conclusion: "The so-called cultivation system is just a supernatural knowledge system. As long as you master the underlying foundation, you can pile up a pyramid that is 10,000 feet high. ”

Lu Yun began to carefully summarize those cultivation knowledge in his mind again.

In fact, the entire content of the cultivation knowledge in his current memory can be summed up, and there are only three basic points.

First, cultivation is linked to the meridians of the human body.

The so-called introduction to cultivation is nothing more than the need for cultivators to be able to absorb the spiritual energy between heaven and earth to warm up the meridian network of the whole body.

When the meridians of the whole body are opened through the aura of heaven and earth, it is considered to enter the realm of qi refining.

Second, the aura of heaven and earth.

Of all the cultivation knowledge in his mind, there were a total of fifty-six mentions of heaven and earth aura.

The entire knowledge point is actually to teach cultivators how to absorb the aura of heaven and earth.

What five hearts to heaven and so on.

Of course, there are other postures, according to Lu Yun's opinion, in fact, this cultivation posture is not fixed, anything is fine, and it is not impossible to lie down.

Third, why can't he.

The reason is actually very simple, that is, not everyone can absorb the aura of heaven and earth in this world.

The meridians of his body were relatively blocked, and the spiritual energy of heaven and earth was not absorbed enough when he was cultivating.

This situation is not without solutions, such as eating elixirs that open up the meridians, finding a cave with very abundant aura, and so on.

However, it is not very feasible.

"So that's to say," Lu Yun summed it up briefly: "It's just that the aura is not enough." 10 parts of heaven and earth aura can be absorbed by others with five parts, but I can only absorb one, so naturally I can't. But if you increase the total amount of aura, it may be a feasible way. 100 units of Heaven and Earth Aura Others absorb fifty, then if it is 1000 units of Heaven and Earth Aura I can absorb 100, and it is the same. ”

The problem is not complicated.

In Lu Yun's eyes, this kind of thing can almost be regarded as the knowledge range of primary school students, and there is no difficulty.

Therefore, the question that Lu Yun is thinking about now is what is the real underlying foundation of cultivation.

That is, the aura of heaven and earth, what is it exactly.

As long as this thing is analyzed, then the subsequent cultivation process is just the application of knowledge points.

So much for.

As a scientific research worker, it is a basic professional quality to think about it.

So Lu Yun began to think.

He had also read a lot of novels before crossing over.

For example, at the beginning of a novel, "The power of fighting, three paragraphs!" ”

With his super memory, Lu Yun could even easily memorize the entire 300,000-word opening.

I can't say that a word is good, and there is no problem with eight or nine without leaving ten.

Therefore, looking at the group of books, everything that is linked to cultivation has one of the most important things, that is, the aura of heaven and earth.

This is the foundation of all cultivation side worlds, the foundation at the bottom.

This thing is called Dou Qi in the Dou Qi Continent, Mana in the Magic Continent, and Aura in the Xiuzhen Continent, and the names are different, but they are actually all the same thing.

Just like the number one, the capital is "one", the English "ONE", and the Arabic numeral "1" is a meaning.

The core is all the same.

It's something that allows people to cultivate beyond the upper limit of human strength.

So what Lu Yun was thinking about was what this heaven and earth aura was and how to obtain it.

If you master this, you will naturally be able to get twice the result with half the effort for cultivation.

"According to what we know so far, the aura of heaven and earth can only be felt when people are at their quietest, but I think this is a pretending to be a ghost."

Lu Yun touched his chin and began to reason very seriously-

"First of all, this heaven and earth aura needs to be absorbed by the human body, and there are generally two ways for people to absorb things. One is to eat, and the other is to breathe. And in the entire introductory knowledge of cultivation, there is never any specific thing that needs to be eaten. ”

"Since it's not eating, then it's only breathing."

"Since it is breathing, then this heaven and earth aura must exist in the air."

"Since it's in the air, it must involve the composition of the air."

"Objects in this world can burn, and since they can burn, there must be oxygen in the air. If we deduce this way, the atmospheric structure of this world should be inseparable from that of the earth, and the main components should be nitrogen and oxygen, plus the aura of this heaven and earth. ”

"If this air composition is really like this, then as long as the nitrogen and oxygen are separated, what is left must be this heaven and earth aura."

"So if I can separate the air, I can artificially refine the aura of heaven and earth."

The more I think about it, the brighter Lu Yun's eyes become, artificially refining the aura of heaven and earth, it's very touching to think about it!

His absorption ratio is not high, so what's the matter, as long as the total amount goes up, the amount of absorption will naturally be higher, right?

"But the harder thing is that I don't have the tools......"

As the saying goes, if you want to do a good job, you must first sharpen your tools.

Without tools, you can't do anything.

But he didn't want to, at this time, a cold mechanical voice sounded in Lu Yun's mind.

"The Heavenly Dao Laboratory has discovered the host and started binding!"

Lu Yun: "!! ”

On that day, a little red rabbit from the blue star gradually smiled fiercely......
