Master Luo replied very honestly.

"Oh? Is that so? ”

Qian Fei'er raised her eyebrows, she touched her chin with one hand, and groaned slightly.

In this way, if you want to refine oil, you should use the distillation method of boiling at different temperatures, and you need to add additives? Or are there other conditions?

Qian Fei'er thought about it for a while, and finally made a decision in her heart.

Well, let's just experiment with it all so you know what to do......

After making up her mind, Qian Fei'er went to the arsenal after going to the morning court for a month, and after a month of continuous testing, she finally ...... Succeed with flying colors!

Wuhun Empire North, Heaven Dou City, Wuhun Empire Arsenal, Autumn, Afternoon.

The temperature of the Wuhun Empire in autumn has dropped a lot, unlike the south of the Douluo Continent, because it is located in the cold temperate zone, and at the beginning of autumn, the weather can make people feel a trace of coldness.

In the sky, the cloudless sky is blue, and it looks like a blue ocean, boundless, refreshing.

On the ground, the air temperature during the day is good, the temperature is about 20 degrees, not cold, not too hot, just right to wear a dress, if it is later, at night, the temperature will drop a lot, at that time, you can't go out without wearing long sleeves and long pants.

In the arsenal, it was still the same laboratory, and Qian Fei'er was sitting at the experimental table, operating a set of glassware.

There are several types of glassware, one of which is a spherical bottom with a gooseneck-shaped glass tube at the top, the bottom of the ware is flat, and it rests on an iron shelf, and below, a bottle of alcohol is emitting an orange-yellow flame.

Gooseneck beaker!

At the other end of the gooseneck beaker, a cylindrical glass is placed to hold the liquid that comes out of the gooseneck beaker after boiling and cooling.

Inside the gooseneck beaker was a dark black viscous liquid mined in the open pit in the northern part of the Wuhun Empire.

Petroleum!

At this moment, the oil in the gooseneck beaker was already boiling, and the viscous dark black near-solid liquid was constantly tumbling upward, and some hot steam was rising upward.

The gas touches the top of the gooseneck beaker and moves down the gooseneck-shaped glass tube, cooling it down and flowing into the cylindrical glass.

Light oil!

In the laboratory, after the oil has been boiling for a while, no more steam comes out, and no light oil enters the cylinder glass.

Qian Fei'er extinguished the flames, closed the door and blocked it with a heavy steel plate, and put away all the lighter, thinner, and brittle things in the room.

Of course, there are also many glasses for distillation, alcohol lamps, and so on.

Putting everything away, Qian Fei'er's slender jade hand wiped on the soul guide bracelet on her wrist.

"Boom!"

A huge, heavy granite table appeared in the lab, shaking the ground slightly!

The dust on the ground was flying in all directions visible to the naked eye, enough to see the staggering weight.

Taking out the granite table, Qian Fei'er's slender jade hand wiped it on the soul guide bracelet on her wrist again.

"Boom!"

A steel cylinder appeared on the ground, and the outside of the bottle was written in red ink with four large characters "liquefied biogas".

Wuhun Empire liquefied biogas cylinder!

As a vessel for the storage of liquefied biogas, the liquefied biogas cylinder is very strong, thick and heavy, and resistant to high pressures.

Qian Fei'er took out these two items that were quite a good weight, and took out the previously distilled oil from the soul guide, and then took out a rather thick steel gooseneck cup.

There is a slit in the middle of the gooseneck cup, Qian Fei'er picked it up with both hands, and twisted it with a little force in her right hand.

"Poof!"

The steel gooseneck cup is twisted open.

Qian Fei'er held the lower half of the steel gooseneck cup in her left hand, and in her right hand, she took the oil that had been distilled once before, and poured the remaining oil into the steel gooseneck cup.

Well, she twisted the steel gooseneck cup again, put the glass gooseneck cup away, then put the steel gooseneck cup on the iron rack, then took out a steel measuring cup and put it on the steel gooseneck cup outlet.

Ready, Qian Feier took out another steel pipe, connected it to the opening of the liquefied biogas cylinder, opened the spiral bolt of the liquefied biogas cylinder, and lit the flame with a small match at the outlet of the steel pipe.

"Boom!"

The flames burned, and the flames began to raise the temperature of the small laboratory.

It was also at this time that Qian Fei'er's soul power was released and she exerted her martial soul.

"Bang bang bang ......!"

A clear bone explosion sounded, Qian Fei'er's feet lifted off the ground, six golden wings brighter than the sun appeared behind her back, and a helmet outlined by soul power appeared on her head.

It's just that, unlike before, Qian Fei'er's current soul power helmet has completely turned into a brilliant gold, without any other color, and the two horns on the top of her head that curve upwards to the Heavenly Demon have also disappeared, replaced by a crown-like ornament.

The crown released an incomparably majestic and sacred aura, and its sacredness far surpassed that of Qian Nawei and Qian Linjue and others, even if their holy aura was combined, I am afraid it could not be compared with Qian Fei'er at this moment.

Absolute ruler!

Casting the martial spirit, Qian Fei'er's arms bulged with muscles, and then with a little force, he closed to the middle!

"Click, click, click......!"

The space around them twisted, all the dust fell in an instant, and the air became so heavy that it seemed as if it was difficult to breathe.

"Whew!"

The flame of the burning of the liquefied biogas cylinder was directly extinguished, not because it was crushed by Qianfeier, but because the connected biogas could not be released from the biogas cylinder.

The pressure becomes higher in vain, and the pressurization test!

Finding the situation, Qian Fei'er squatted down, squatted next to the biogas cylinder, and wrapped one hand around the steel liquefied biogas cylinder that was so heavy that it required an adult man to carry on his shoulder, and used a little force...... It turned out to be just holding it and standing up!

Moreover, Qian Fei'er's face was not red or panting, except for the muscles that were visible to the naked eye on her arms, on her forehead and on the back of her hands, there was not a single green tendon bulging!

The strange power is amazing!

Picking up the liquefied biogas cylinder, Qianfeier adjusted the direction so that the opening was lowered, so that the liquefied biogas could flow out again.

As she operated, she pulled out a small ring-like soul guide from her body.

This small soul guide was prepared by Qian Fei'er in advance, and it contained a little bit of hell flame stored by Qian Yuqiong.

Taking out the soul guide, Qian Fei'er moved her fingers slightly.

"Poof!"

The Soul Guide emits a purple infernal flame that ignites the liquefied biogas from the liquefied biogas cylinder.

It was also at this time that the steel gooseneck cup became heated and began to make a slight noise......

After a period of time, Qian Fei'er heard the sound of "gurgling ......" constantly boiling and tumbling, and at the same time, inside the steel measuring cup, the mouth of the steel gooseneck cup began to flow down some darker liquid.

The second distillation separates the oil, and it is a success!

Qian Feier was very pleased with the success of the test, and in the next day, she carried out several pressurized distillations in a row, and successfully refined a variety of oil contents such as aviation diesel and gasoline.

After all the refining was completed, Qian Fei'er put down the liquefied biogas cylinder, lifted the high temperature and high pressure in the laboratory, and wiped the sweat on her forehead.

In this afternoon, it can heat her up, and under high pressure, the indoor temperature is very high, several times that of the outside!

Now, Qian Fei'er was soaked with sweat all over her body, and the golden plainclothes were clinging to her, and it was good that she was wearing more than one layer, otherwise, her perfect stunner-level figure would be exposed to the public as soon as she went out.

"Hmm~, I'm tired."

Qian Fei'er stretched her waist, put away all the props and restored the laboratory, she removed the heavy steel plate blocking the door and walked out of the laboratory......

After that, the first oil well ordered by Qian Feier officially began to extract oil on a large scale, and at the same time had the function of oil refining, and the refined aviation diesel was directly used in the modification of various aircraft, from the original propeller aircraft to the jet type.

In addition, some of the oil extracted from petroleum is also used as a raw material for clothes to make polyester clothes.

Clothes with polyester added are more wear-resistant and durable than the original cotton clothes, and the comfort does not drop too much, which is perfect!

In addition, after the oil was refined, a large amount of asphalt was obtained, which was ordered by Qian Feier to be used directly to repair the road.

The large use of asphalt replaced the bluestone floor tiles, and the cost of building roads was greatly reduced, and the Wuhun Empire rose up for a while to build roads, and many soldiers of the Star Luo Empire who were captured by Qian Nawei some time ago were transferred to build roads.

Moreover, these captured soldiers of the Star Luo Empire were not paid, only food, and Qian Fei'er saved a lot of costs.

It's wonderful!

Qian Fei'er thought happily in her heart.

And after the experiment was successful in refining oil, Qian Fei'er threw herself into the next experiment, this time, she aimed at ...... Nitroglycerine!

The north of the Wuhun Empire, outside Tiandou City, weapon test range, afternoon.

Qian Fei'er, with long blond soft hair and squinting eyes, stood in front of a simple wooden table.

On the wooden table, there is a glass beaker with a clear solution.

Still a certain distance, Qian Fei'er could smell the pungent sour smell in the beaker.

And in the middle of the beaker, on the outside, there is also a label with two words written on it, "nitric acid"!

Qian Fei'er stood at the edge of the table, holding up a soul power shield at a certain distance, holding another beaker in her right hand, tilting slightly.

The beaker in Qian Fei'er's right hand also contains a transparent liquid, but there is no pungent sour smell in it, and the outer label is not "nitric acid", but "glycerin".

Holding glycerin in her right hand, Qian Fei'er carefully and little by little injected glycerin into nitric acid.

Her movements are very gentle, like caring for a bird in her hand, for fear of the slightest injury.

But......

At this moment, suddenly, a little wind blew in the sky, which is very common on cool autumn days, bringing a little coolness.

As a little autumn wind blows, the glycerin is slightly deflected, and when it is poured in, it comes into contact with nitric acid and has a little, very fine ...... Concussion!

"Bang ——!"

The earth-shattering explosion sounded, and a powerful wave of qi flew outward, and everything in the center was instantly blown to pieces!
