"The Heavenly Dao Laboratory is dedicated to assisting the host in researching the knowledge of the cultivation realm to improve their own strength, and at the same time, they can also create more and stronger weapons." Listening to the sound of the system, Lu Yunle's mouth almost couldn't close.

Tears of excitement flowed down the corners of his mouth involuntarily.

He was a science maniac before he crossed over.

Although he is only 27 years old, he is also a fierce person who has published several international-level papers.

I originally thought that he might be at a loss in this world without those modern tools, but he just got such a great thing.

What is it?

This is Goldfinger!

Is there a problem?

No problem!

"Heavenly Dao Laboratory?" Lu Yun asked in his mind, "Do you have any functions?" ”

The mechanical voice sounded again: "The main function of the Heavenly Dao Laboratory is to provide all kinds of experimental raw materials, equipment, tools, and so on. The specific device requires the host to have a clear idea concept, and the system can automatically generate relevant tools for the host to use. ”

Lu Yun: "!! ”

it!

Listening to this explanation from the Heavenly Dao Laboratory, this function is simply so powerful that it is boundless!

As long as you want any tools, what tools can you have in this lab?

Lu Yun hurriedly asked, "Then, how did the tool get to me?" ”

Mechanical voice: "The host only needs to send out the demand information in his mind, and the laboratory can receive it, and then transmit it to the host, and the large experimental tools will automatically be transmitted to the host's side." The specific functions and sizes of the experimental tools will be provided according to the strength of the host, if the strength of the host is insufficient, the corresponding experimental tools will not be able to be transmitted. ”

Coat.

As soon as he said this, Lu Yun immediately understood.

It's the same as learning to do experiments in school.

Naturally, elementary school students can only have books and props from elementary school.

He can't use college-level stuff for him, can he?

Understand.

"Then, the Heavenly Dao Laboratory, right?" Lu Yun thought for a while, and then asked cautiously: "Can you provide a set of tools for determining the composition of air now?" For example, paper, pens, beakers, alcohol lamps, test tubes, phosphorus ......"

Lu Yun said more than a dozen experimental tools related to testing air in one breath.

Soon, when he finished speaking, he saw that on the table in front of him, the space was distorted for a while, and then all the materials he needed appeared on the table!

Lu Yun: "!! ”

it!

It's true! It's really out!

Awesome!

It is worthy of being a Tiandao laboratory, what do you need, wahahahaha!

Lao Tzu is invincible!

As long as you give Lao Tzu a laboratory, any big killer will be made for you!

As long as you dare to show the blood bar, the gods will kill you!

Lu Yun felt happy in his heart, so he began to experiment.

The experiment of testing the composition of the air was at the junior high school level for Lu Yun at best, so naturally there was no problem.

The process of analyzing the composition of air is actually quite simple.

First of all, it is necessary to determine the proportion of nitrogen and oxygen in the air.

As for whether the aura of heaven and earth can burn, this needs to be done experimentally to know.

Immediately, Lu Yun began to record with a pen on paper-

【Experimental principle】Red phosphorus is burned in the air and consumes oxygen to produce phosphorus pentoxide.

【Experimental device】The spring clamp is closed. Add a small amount of water to the cylinder and mark it.

【Experimental Procedure】:

(1) Connect the device and check the air tightness of the device.

(2) Concentrate the light through a magnifying glass to ignite the red phosphorus in the burning spoon.

(3) After the red phosphorus is extinguished and cooled, open the spring clamp.

The experiment begins.

Lu Yun followed the steps step by step, and soon the results of the experiment came out.

Red phosphorus burns, producing a large amount of white smoke.

Exothermic.

After cooling, the spring clamp is opened, and the water enters the gas collection cylinder along the conduit, and the volume of water entering the gas collection cylinder accounts for 22% of the total volume of air in the gas collection cylinder.

Lu Yun recorded: "The oxygen content accounts for 22% of the air, and theoretically speaking, the remaining part is the sum of nitrogen and heaven and earth aura, accounting for nearly 78%. ”

Once the recording is over, the next step is to do the same experiment again to see what the percentage of nitrogen is.

The laboratory separates nitrogen from the air, typically by burning magnesium strips.

3Mg + N2 = ignition = Mg3N2 (magnesium nitride).

The experiment process is the same as burning oxygen, and Lu Yun's final result is that the proportion of nitrogen in the air is 76%.

"So in other words, about 2% of the air is heaven and earth aura, which is the same conclusion I came to."

Lu Yun raised his eyebrows excitedly.

This is very important.

The air composition of this cultivation realm is about 76% nitrogen + 22% oxygen + 2% heaven and earth aura.

Therefore, only the oxygen and nitrogen can be separated through the equipment, and the rest is all heaven and earth aura?

Even if there may be some impurities such as carbon dioxide and hydrogen in it, that's not a big problem, is it?

"So the next thing you need is the equipment."

Lu Yun touched his chin and began to think carefully in his mind about what kind of equipment he needed.

First of all, people need to breathe oxygen, and this device can't run out of oxygen.

Then, the oxygen ratio should not be too high, otherwise it will be drunk with oxygen, which will also be very troublesome.

Thirdly, it is necessary to reduce the proportion of nitrogen in the air and increase the proportion of heaven and earth aura.

In this way, a total of three pieces of equipment and a suitable site are required.

The first is the site, which must be relatively sealed to keep the air structure stable.

This room is pretty much fine.

Then, there is the first device, which is also the core of the core, this device can inhale the outside air on a large scale, and then filter out all the oxygen and nitrogen in the air, leaving only the heaven and earth aura.

The second device can filter out the nitrogen in the room air.

As for the third one, it is just an air structure ratio tester, which is used to monitor the air structure at any time.

In this way, theoretically, the proportion of nitrogen in the air in the room decreases, the proportion of oxygen remains the same, and the proportion of heaven and earth aura continues to increase.

If everything goes well, it means that the air structure in the room can be changed to 40% nitrogen + 22% oxygen + 38% heaven and earth aura.

If you can reach the limit, it will be 22% oxygen + 78% heaven and earth aura......

39 times the aura of heaven and earth!

Lu Yun's eyes lit up!

This is simply invincible, is it?!

As soon as he thought of it, Lu Yun immediately began to communicate with the Tiandao Laboratory in his mind: "The equipment I need is about this, this, ...... like this."

When he finished communicating with the laboratory perfectly, he suddenly heard a bang, and two devices about one meter square, as well as a device the size of a mobile phone, appeared in front of him!

Lu Yun: "!! ”

it!

It's so easy to use!

It's a bunker, isn't it?!

"Lab, don't mind," Lu Yun grabbed his hair and hurriedly continued: "It will be a problem to be found out if you put it here like this, can you hide it a little?" For example, hiding in a chimney, under a bed, etc. ”

Immediately, there was another smack.

A large wooden box appeared under the bed, which, according to the laboratory's explanation, was an oxygen and nitrogen remover, with an intake inlet attached to the top of the room, a hidden entrance.

The other box is against the window wall, which can filter the nitrogen out of the room.

It was perfect.

Lu Yun expressed 120,000 points of satisfaction this time.

"Laboratory, give you a heart!" Lu Yun lay down on the bed with a smile: "Let's get to work!" Hahahaha! ”

"Whew-"

An extremely faint sound of air currents began to sound.

Lu Yun's eyes were firmly fixed on the monitoring equipment in his hand.

The values above are starting to change.

Current air structure: "Nitrogen: 70%, oxygen: 22%, heaven and earth aura: 8% ......"

It's started, and this time it's four times the aura of heaven and earth, it's powerful!

When Lu Yun breathed, he felt a little hot all over his body, and according to the memory in his mind, the meridians of his body began to flow with breath, which was a sign that he was beginning to absorb the aura of heaven and earth!

It's just two words, awesome!

The structure of the air continues to change –

"Nitrogen: 62%, Oxygen: 22%, Heaven and Earth Reiki: 16% ......"

8 times!

Lu Yun's body began to sweat, and black impurities began to appear on the surface of his body.

This is the stage when the meridians begin to fully receive the warmth and nourishment of the spiritual energy of heaven and earth, and eliminate all kinds of toxins and impurities.

"Nitrogen: 48%, Oxygen: 22%, Heaven and Earth Aura: 30%......"

15 times!

Lu Yun was like sweating at this time, his skin was red, and a lot of sweat flowed out.

If the flow of breath in the meridians of the whole body was a small flow of water before, then at this time it is definitely a high-pressure water pump, and the speed of the flow is simply violent!

"No, no, no, first hold your hand!"

Lu Yun was frightened, and hurriedly asked the laboratory to stop the operation of the machine first.

After all, if you are a newcomer, you can't be too anxious, just take it slowly.

Otherwise, I am afraid that the body will not be able to bear it.

Maintaining the current 15 times the aura of heaven and earth, Lu Yun lay on the bed, according to the knowledge in his mind, controlled the aura of heaven and earth in his body, and began to rush through the level step by step.

Hand Taiyin Lung Meridian, Hand Yin Pericardial Meridian, Hand Shaoyin Heart Meridian Break through!

Hand Yang Ming large intestine meridian, hand Shaoyang Sanjiao meridian, hand sun small intestine meridian break through!

In the evening, Lu Yun finally fought hard, and the Zuyang Ming Stomach Meridian, Zu Shaoyang Gall Meridian, Zu Sun Bladder Meridian, Zu Tai Yin and Spleen Meridian, Zu Shao Yin Liver Meridian and Zu Shao Yin and Kidney Meridian were all broken!

At this time, Lu Yun was already refining qi in half a step!

As long as he breaks through the last Du Pulse and Ren Pulse, it means that he has officially stepped into the Qi Refining Realm, and the spiritual power test after seven days will be stable without any problems!

"Oh, how else to say it," Lu Yun finally got up from the bed, opened the window, looked at the starry sky outside, and smiled: "Knowledge is power!" Isn't it just a qi refining, isn't it a hand-to-hand capture? ”

Now that he is only half a step away from completely entering the Qi Refining Realm, he took a cold shower first, and Lu Yun looked in the mirror again-

Look at my brother's appearance, sword eyebrows and starry eyes, eyes like cold stars, and lips like painted Zhu.

Put it on the earth, and the four beautiful men in ancient costumes can break their wrists!

Awesome!

Let's go to the spiritual cafeteria to eat!
