Zhang Shengye had a great time playing. He controlled the fireball and kept spinning up and down the table.

"If the world is flat, if the sun rotates around the earth, then the sun just rose and was very close to the east and west edges of the earth when it just set.

That is why there will be morning glows in the morning and fire clouds in the evening. Because at that time, the sun was closest to the earth, and the earth was burning."

Zhang Hao:...

I can't even refute it.

Finally, Zhang Shengye looked at Zhang Hao proudly: "Little mouse, I know I feel very smart recently, but the earth is spherical, which is ridiculous."

Then, Zhang Shengye pulled Zhang Hao to the roof, pointed to the distance and said, "Look, as far as you see, is the earth curved?

If the earth is spherical, then when we look at the houses in the distance, we should only see the roof, rather than the entire house.

OK, stop making trouble.”

Zhang Shengye flew away, leaving only Zhang Hao in the wind.

What Zhang Shengye said makes sense. But Zhang Shengye did not consider this: the world is big, and people are very small, and they are so small. From the extreme method, the limited earth that the human eye can see is indeed flat!

As for the distance, the obstruction of air, dust, water vapor, etc., it is impossible to see it clearly.

Because this planet is too big, it has hindered people's exploration of the earth.

Yes, if this world was not big, with the ability of a cultivator, the facts would have been discovered long ago.

"It's so fucking... it's interesting!" Zhang Hao sighed helplessly, and did not spit out the swear words after all. After a while of silence, he flew down the roof and greeted his mother.

Zhang's mother is a typical family woman who rarely appears; she spends most of her time practicing. She is under pressure.

Zhang Shengde has reached the peak of the Golden Pill and is about to be in the Nascent Soul stage, which means thousands of years of life.

She was afraid that when Zhang Shengde was in high spirits, she would get old.

Therefore, Zhang Hao rarely sees this mother. She spends most of her time practicing.

Zhang Hao hurriedly greeted him and left.

When I arrived at the door, I looked at my father's caravan leaving, and sighed leisurely.

The world of cultivation also has the trouble of life span.

After returning to the bedroom and practicing for a while, he swallowed a small spiritual essence pill, suppressed his cultivation and consolidated his foundation, and Zhang Hao came to the smelting base.

To be precise, it is the 'classroom' of the smelting base.

Huang Mingshan and others completed a brand new machine today, a machine that can output power.

This is a machine with a "rotor". Its rotor is four rows in front and rear, with a total of 16 windmill blades, surrounded by wind formations.

The wind formation generates wind power, which in turn drives the rotor to rotate.

The power is not small, two low-level spirit stones can generate the power of almost an ordinary horse; but two spirit stones can only last for less than an hour.

Zhang Hao nodded, very satisfied with the breakthrough progress. Although the machine is very crude, the bearing is not a ball bearing, but a hand-polished iron ring with butter. As for fluid, aerodynamics, blade design, etc., there is nothing at all.

But this is still of great significance.

This is the first 'mechanical prime mover'.

Previously, the fans could only use the air conditioner, and they could not do anything except the air conditioner.

But now, it is a real machine that can output power.

Zhang Hao gave chief designer Huang Mingshan a generous reward. 10 small spiritual essence pills!

The value of the Little Spirit Yuan Pill is not below the Foundation Building Pill; as a pill that can purify the true qi of the Qi Refining Cultivator and consolidate its foundation, the market demand is very high, and the price is relatively high.

Zhang Hao also rewarded one or two small spiritual elixirs based on their respective contributions.

Huang Mingshan was a little trembling. He didn't expect that he just copied the effect of the windmill and built a machine with almost no practical value, which was even greater than the reward for producing the fan!

However, Zhang Hao did not care about everyone's reaction, but began to "cheat". He began to guide everyone how to design the inner blade rotor.

Opening cheats does not mean that you can help grow; there are a lot of research and failures that should be found. Just like practicing, the foundation must be firm!

This is a huge project, inner blade rotor machinery, with wide applications in another world.

Aero engines are one of the peaks; steam turbines and gas turbines that drive the generator to rotate are also one of the peaks; the most powerful mechanical power in the era of giant ships and cannons comes from steam turbines.

Even the most powerful nuclear-powered aircraft carrier, the core device of its energy is still a steam turbine. The gas turbine converts the thermal energy (ultra-high temperature and ultra-high pressure water vapor) from the nuclear island into mechanical kinetic energy that drives the generator to rotate.

Also, many industrial-grade 100,000-ton and million-ton compressors, high-pressure pumps, etc. mostly use inner blade rotors.

Zhang Hao did not expect that Huang Mingshan and others would take the lead in opening the door to industry from this direction.

So Zhang Hao was surprised and excited.

Huang Mingshan and others who received the reward were equally excited. Everyone devoted themselves to study and research with twelve percent enthusiasm. Time slipped away quietly, but everyone was not tired at all - Peiyuan Dan was supplied in batches.

The leaves, under the guidance of Zhang Hao, began to change little by little.

The rotor begins to become slender and the blades become fine and delicate.

The machine's shell is also beginning to change. High-pressure cylinders, medium-pressure cylinders and low-pressure cylinders have appeared.

The wind formation and the fire formation are used in conjunction with each other. The flame heats the air, and the high-temperature and high-pressure air rushes through the blades.

The ability of cultivators has greatly improved the efficiency of design and production.

Also, knowledge such as mathematics and physics has also been developed and progressed in research and practice.

Before I knew it, it was already a few days later...

…………

By the way, when Zhang Hao started to improve the machinery, Zhang Shengde was called by the city lord.

After meeting, the city lord asked with a stern face: "Zhang Shengde, you have done such a big thing!"

This powerful conversation couldn't scare Lao Zhang - this morning, I was just startled by my son's "sphere world".

So Lao Zhang said leisurely: "City lord, it is the responsibility of every man who has the rise and fall of the country. I can't bear the chaos in the Xuantie market, nor the pain of ordinary people. The Zhang family just did what they could.

Zhang Shengde expressed his honor to have some small things in his eyes as the city lord."

City Lord: Did I praise you just now? What are your ears?

However, as the saying goes, the smile is not a hit on the smiling person. Seeing Zhang Shengde so humble, the city lord's vanity is satisfied. A smile immediately appeared on his face.

"Master Zhang, I'm very surprised by this Xuantied Guild. How did you think of this?"

Zhang Shengde's face was serious and solemn: "City Lord, although we have produced black iron over the years, the pricing power is not in our hands.

Ultimately, it is because we are not united. The other party can negotiate prices one by one.

Therefore, we must unite and we must take the initiative in pricing.

We will also be committed to the advancement of black iron technology and will provide the country with more high-quality and cheap black iron!

In addition, the guild has many functions that can stabilize the price of black iron, control the depreciation of black iron coins, and benefit ordinary people, small and medium-sized families and businesses.

It can also uniformly dispatch resources and further reduce the production cost of black iron.

The most important thing is that we can unite and say 'no' to foreign countries!"
