Nangong Zhi walked into the secret research base of the country of Shaoze, this research base is underground, and it is fortified layer by layer, unless more than a dozen transformation stages attack at the same time, it is impregnable. Nangong Zhi himself had tried to attack, but he could barely shake it.

A large amount of dark iron in the country of Shaoze has been used to build this secret research base. There are many techniques of the Daeyang Group that are being studied here, as well as the technical system of traditional practice.

Zhongxingyue walked around the research base with Nangong Zhi and began to introduce:

"This is a research base for dark iron, and our main purpose is to study dark iron with a purity of more than 98%. At present, although Dayang Group has disclosed the production technology of 98% and below of dark iron, this technology cannot reach more than 98%, and it is difficult to achieve 98.1%.

We are working on higher purity darkiron.

The higher the purity of the dark iron, the better the performance, and the stronger the plasticity. Especially after the purity exceeds 99%, it can be used to make spiritual weapons.

In the past, spiritual weapons were very precious, because the spiritual materials that could be made into spiritual weapons were very rare, and most of them were very small amounts of natural high-purity spiritual materials such as pure gold or easy to purify.

But now the cost of spiritual weapons has been reduced several times, and the reason is that Dayang Group produces more than 99% of the dark iron in large quantities and sells it publicly. ”

Nangong Zhi nodded slowly: "Then have you ever studied the secret of the Ocean Group?"

Zhongxingyue shook his head, but nodded again: "We have not been able to research the technology of Dayang Group, because the cost price of the technology we use is almost the same as the selling price of Dayang Group. Obviously, there is something in it that we have not eaten through.

But we have also developed our own high-purity dark iron technology.

We re-crush, heat, and turn 98% of the black iron into rust in an environment that isolates the aura, and then repeats the previous process.

After four purifications, the purity can reach more than 99%.

At present, the technology has been preliminarily finalized, and if the factory produces it, it is expected that after completion, there will be no problem with an annual output of 1,000 tons of 99% dark iron. According to the calculation that a spirit-level flying sword flying sword requires 5 kilograms of Xuantie, a thousand tons is enough to build 200,000 flying swords and Lingbao-level flying swords, which is enough for all soldiers above the Jindan stage to have one each.

In addition, if the black iron is mass-produced, the cost can be reduced to 80% of the selling price of Dayang Group. ”

Nangong Zhi nodded, "It's already very good." Cheaper than the Ocean Group's, and also in control of your own destiny, you are doing well. ”

The sword bar of a flying sword is generally between two catties and three catties, but there is loss during the forging process, and the loss is often as high as 50%. Sometimes a good sword is repeatedly folded and forged, and the loss is as high as ninety percent. (Note)

And Lingbao is very demanding, and a flying sword is about the same as five kilograms.

Zhongxingyue continued to move forward with Nangong Zhi, but the next target was the research base of steam turbines.

"According to my research, Dayang Group has two cornerstones, one is black iron and steel, and the other is steam turbine.

Steel technology, we still have no clue, can only temporarily run aground. The research on Xuantie has already achieved initial results, and the focus of the next step was originally to prepare to conquer the steam turbine.

I've seen studies in other countries, even in the Holy Land, where they only focus on the dark iron and ignore the seemingly frivolous steam turbine.

In fact, Xuantie and steam turbines are the two legs of industry, and one is indispensable.

The dark iron is the body, and the steam turbine is the power, which can replace the power of manpower and animal power, a completely artificial power, especially the steam turbine can be driven by cheap oil, which is incomparable to the traditional formation.

And the steel battleship is the best product of this technology. In addition, there are trains, etc. ”

Nangong Zhi nodded, thought for a moment and said, "Then this research project will continue to be kept." ”

"Yes. Zhongxingyue took Nangong Zhi to visit the research base of steam turbines, where the machine tools were purchased from Dayang Group. Even many of the researchers here were taken from the 'dark iron factory built with the help of the Dayang Group'.

At the beginning, Dayang Group agreed to Nangong Zhi to build a turnkey Xuantie production plant, including worker training. And Nangong Zhi took the opportunity to stuff a lot of 'apprentices' in the Jindan period. The Ocean Group didn't care.

Now, many of these 'Jindan apprentices' have been transferred to the research base.

Nangong Zhi looked at the research of steam turbines, and there were steam turbines purchased from Dayang Group next to him, and compared with the steam turbines produced by himself, he always felt an indescribable awkwardness. The machines of the Ocean Group have a strange machine beauty!

"The steam turbines of the Ocean Group, and even the design of their warships, obviously use a technology that is unknown to the outside world. However, there is one point that the Ocean Group still miscalculated.

We have studied many technologies of Dayang Group in detail and found a problem, that is, air flow and water flow. The turbine blades and propellers produced by Dayang Group can allow the air and water to pass smoothly, but ours can't.

But now that we've found the problem, I'm sure it won't be long before we can break through. ”

Nangong Zhi was very satisfied and praised everyone on the spot. But is it rewarded...... It is necessary to wait for the merit to be calculated. Nangong Zhi is a qualified ruler, and he clearly knows that rewards can't be messed around.

After coming out of the steam turbine research base, Nangong Zhi visited petroleum research, artillery and explosives research, machine tool structure research, formation research, etc., and finally came to the core research base.

This is a research base that has just been opened, but the research is crazy - the breath of the fairy!

With the popularization of the ideas of industry and research, not only the Ocean Group thought of studying the spirit of the immortals, but others also thought of it. For example, Nangong Zhi.

Cultivators are not rigid, on the contrary, many cultivators are actively thinking about change. It's just that there is no new direction of change in the past.

Zhongxingyue continued to explain: "Because of the prevalence of the earth circle, we have an idea. If the earth is round, then the pressure in the ground must be very high, and it is higher than you think.

Last month, I took a few Yuanying peaks to dig underground, and dug down to a depth of about 10 kilometers at Happy Horse Mountain in the Jiangdong area, and dug an underground lake. The temperature is much warmer and the water pressure is great.

Based on what is known, the pressure at the depths of the earth will be higher and the temperature will be higher. Therefore, it is possible to produce the qi of the fairy spirit by chance.

When we got back, we had people start experimenting. At high pressure and high temperature, the aura is compressed. ”

"How's that going?"

"For the time being, it has only been researched that the aura that has been treated with high temperature and high pressure is extremely active. The aura in the spirit stone no longer needs to gather the spirit array, and after such treatment, it can be absorbed directly, and the aura situation is comparable to the environment of the holy land.

More on it, still being studied.

But I believe that with the advancement of technology and the increase of pressure, we will definitely be able to study the secret of the fairy qi!"

Nangong Zhi nodded. Although Zhongxingyue is only the peak of Yuanying, he is different from other peaks, because ...... Zhong Xingyue came into contact with the immortal qi, but failed and failed to enter the god transformation stage. But at least Zhongxingyue has been exposed to the immortal qi and knows what it is.

As he spoke, Zhongxing Yue and Nangong Zhi entered this research base. As soon as he entered the gate, Nangong Zhi couldn't help but take a few deep breaths, the aura here was very active, and Nangong Zhi felt that this aura also had a little bit of a good cultivation effect on the transformation period.

That's a lot of money. You must know that ordinary aura has little effect on the transformation period, so Fu Yun only had a regression in his cultivation at the beginning.

After Nangong Zhi took a few deep breaths, he smiled with satisfaction, "The result is good!

The efficiency of using the Spirit Gathering Array to gather spiritual energy is very low, and the utilization rate of the spirit stone cannot even reach one-tenth of it. If you do, you can use it 100 percent, right?"

Zhong Xingyue said: "Because it needs to be heated and pressurized, it needs to consume some spiritual energy. The overall efficiency is around 60%. However, if the fuel turbine technology is used in the later stage, the efficiency of the spirit stone will be greatly improved. ”

Then the two stopped next to a huge 'compression cylinder'. This compression cylinder has a diameter of more than three meters, that is, a diameter of one zhang, and a height of about two zhang. It is topped by a compression bolt two feet long and about six feet in diameter.

This set of equipment is very precise, and it is engraved with dense formation assistance. This includes sealing, preventing aura leakage, etc.

At this time, a new experiment was underway.

The people involved in the operation were all masters of the peak of Yuanying - they all hoped that the research of the fairy qi would bear fruit. Therefore, they are very hardworking and meticulous.

(Note: You can refer to Japanese katana forging, about a ton of grass iron, and in the end, you can only forge four to five hand-me-down katanas.) The blade of a katana is calculated at 1.2 kilograms, and the attrition rate is as high as 99.4% based on five knives. ）
