The morning breeze was slowly drifting, but Zhang Hao had been sitting on the mountain all night.

What Zhang Hao thought of was the invitation of Xinglintang.

The famous Xinglintang actually sent an invitation letter to himself, or a handwritten letter from Zhou Shuhai!

The content of the invitation is very simple, two: a month later, it is the annual alchemy event of Xinglin Hall, and also, the alchemy event is not only alchemy, but also has developed into the largest cultivation trade conference in the country of Qixia, and Zhou Shuhai hopes that the Zhang family can exhibit and sell the special black iron for alchemy at this trade fair.

The influence of this alchemy event even covered the entire six Western countries.

Especially in this war-torn environment, this alchemy event should be very exciting.

But what are you doing with this invitation to my father?

Zhang Hao looked at the rising sun, but he had a little idea in his heart: the weasel greets the chicken, and there must be a picture in the sea of books this week!

Seeing the rising sun, Zhang Hao returned to the base and told his father Zhang Shengde his thoughts.

Zhang Shengde smiled: "You think too much." Xiaohao, you may not have noticed that now you are almost in charge of the Zhang family, inside and out.

Therefore, everyone naturally regards you as the new head of the Zhang family, and this letter should be given to you. Give it to me, but it is a distrust of you, the new head of the family. ”

Zhang Hao covered his heart, and his heart was beating straight...... The waves are rolling!

Recently, I just want to hurry up and establish the industrial system, but I didn't expect that I have shown it so obviously.

Now that I think about it, it's not, my father seems to have rarely come forward recently, even if it is some indispensable appearance, most of them don't speak much, it's all Zhang Hao is saying.

Even the second uncle Zhang Shengye, who was the vice chairman of the Refining Guild, did not attend, but went to the meeting by himself!

Zhang Shengde patted Zhang Hao's shoulder: "You did a good job." It has also been recognized by the whole family. In the future, I am ready to practice in retreat with peace of mind as a solid backing for my family.

Just do it.

Just by virtue of your status as a disciple of the Xuanzhen Sect, few people will dare to touch you! By the way, when you go to the meeting, don't forget to pull Feng Zhiling. ”

After Zhang Shengde finished speaking, he left, as he himself said, to start practicing.

In the four corners, there is a small formation enchantment, which is "boiling spirit stones", and the boiled, extremely active spiritual energy seeps out little by little from the formation, rolling like a thick fog in the secret room.

Zhang Shengde sat down slowly, suddenly opened his mouth and inhaled wildly, and half of the aura in the room disappeared in an instant. Then he closed the seven orifices and entered a state of complete retreat.

The rapid development of the Zhang family, the rapid changes in the country of Qixia, and the treacherous wars in the east all gave Zhang Shengde a sense of urgency.

In fact, Zhang Hao also has a sense of urgency, after Zhang Shengde left, Zhang Hao finally dragged Huang Mingshan and others over to prepare a project that had been delayed:

Oil refining!

It has been more than 20 days since the discovery of oil, and it seems that it will be a month, but because there are too many things, it has been delayed until now. Now, I finally have my hands free.

Huang Mingshan and the others looked at the reddish-brown and blackened liquid in front of them, still a little hesitant. Is this really a treasure?

"The blood flowing from the earth is not a baby!" Zhang Hao's eyes flashed with confidence.

During this period of time, Zhang Hao also repeatedly observed and studied a lot, and basically can roughly conclude the oil composition of this world: in addition to the normal oil composition, it also contains a large amount of aura, to be precise, it contains a large number of 'fragments that have absorbed aura'.

These fragments are similar to the powder of spirit stones, and these powders are very, very numerous, and the oil itself also dissolves quite a lot of spiritual energy.

It's just that compared to the normal aura and spirit stones, the aura in the oil is mixed, and it is almost impossible to use it as a cultivation resource.

But if it's used as fuel, it's no problem at all!

Huang Mingshan frowned and looked at the oil in front of him; Master, this thing...... How do you deal with it?'

Zhang Hao said directly: "I have been observing for more than 20 days, and I have thought of a method, which is to ...... Evaporative condensation. Just like we boil seawater, the water boils dry, but the salt is left.

I thought this method could be tried. ”

With the buffer period of more than 20 days in the past, Zhang Hao can directly propose the distillation method, which is very reasonable.

If you want to distill, you need to have a distillation machine, Zhang Hao drew a rough sketch, Huang Mingshan and others perfected the sketch, and made several different stills.

The test lasted for several days, and we constantly adjusted the structure of the distiller, heating temperature, pressure, level, cooling time, cooling tube length, etc.

Until you have a complete and definitive understanding of oil, you can only improve your technology through continuous experimentation, adjustment, and experience.

Huang Mingshan and the others didn't even rest, they just asked people to talk to their families, and they were busy these days.

When you are tired, meditate and practice for a while and eat some Pei Yuan Dan. Although Pei Yuan Dan is already very expensive now, and the market price has risen to more than 80 spirit stones, Zhang Hao has never been stingy in scientific research.

Pei Yuan Dan was placed on the shelf behind Huang Mingshan and the others, and they could be used casually. This kind of trust and support is exchanged for the loyalty and dedication of Huang Mingshan and others.

I don't know the dozens of adjustments, the six outlets reserved by the still, a brightly colored liquid appeared.

The first exit was some pungent smell of gas, mixed with a thick but mixed aura of oil. In order to cool these gases, it was necessary to use the cold ice formation, which condensed some gases into a slightly turbid liquid at a low temperature of more than minus 50 degrees Celsius and the pressure of the external formation.

The second outlet is a clear liquid, like water, but volatile and easily ignited.

The third outlet is a slightly yellowish-brown liquid, which is also clear, like a fine cooking oil, and is easier to ignite.

The fourth exit is a darker yellow-brown color, which is not very clear and is easier to ignite.

The fifth outlet is a viscous liquid, which is already a little dark brown, and it can also be ignited, but it is a little harder.

The sixth outlet is a viscous, completely opaque black liquid, which is very sticky and slippery.

Finally, there are still two substances left at the bottom of the still, one is like a colloid, which flows slowly at high temperature and solidifies at low temperature, because a large amount of petroleum remains and is red and black, and the color is a little weird.

There is also the lowest layer, a layer of charred black substance.

A large amount of debris containing aura in the oil remains at the bottom layer.

When Zhang Hao announced that the distillation had achieved a phased success, Huang Mingshan and others cheered. But then there is the question - how did this name come about?

"The first one is called liquefied petroleum gas. Chen Feng said.

Zhang Hao immediately smiled: "Not bad." ”

Liu Ming said: "The sixth kind of butter is like the one we usually use, which can be used as lubrication. Let's call it lubricants. ”

Hou Shangzhuo was not to be outdone: "The second to the fourth, I think it can be named: high-grade, medium-grade, and low-grade fuel." The fifth is named: diesel. This diesel fuel is like firewood and grass, it can be ignited, but it is not easy. ”

Zhang Hao nodded, although he really wanted to move out names such as gasoline and kerosene, but he still forgot about it. It's just a name.

Huang Mingshan looked at the black-red viscous substance, thought for a moment and said, "This is like an oil stain mixed with dirt that seeped out of the corners of oil extraction. It is commonly called 'residual oil' in the folk and 'asphalt' in some places. ”

"Call it asphalt. Zhang Hao settled on this name.

Finally, Zhang Hao pointed to the residue at the bottom: "This is called coke, similar to charcoal and bamboo charcoal." ”

Huang Mingshan carefully recorded his name.

Zhang Hao clapped his hands: "Okay, the oil separation, the preliminary completion." Let's continue to work hard to determine the properties of each one, see what can be done, which one is most suitable for smelting steel, and estimate the cost.

It's been so many days, let's go back and rest first. Rewards will be issued for a few days. ”

Zhang Hao left the research base, but saw Feng Zhiling eating dragon meat hot pot again.

Seeing Zhang Hao coming out, Feng Zhiling greeted: "Senior brother, your father-in-law is here, hurry up." ”

Zhang Hao was stunned, wasn't he at war?
