Zhang Shengye had a great time. He controlled the fireball and kept spinning it up and down on the table.
"If the world is flat, and if the sun revolves around the earth, then when the sun just rises and sets, it will be very close to the east and west edges of the earth.
That’s why there are the morning glow and the burning clouds at night. Because the sun is closest to the earth at that time, the earth is burning.”
Zhang Hao:......
I really can't refute it.
Finally, Zhang Shengye looked at Zhang Hao proudly: "Little mouse, I know I feel very smart recently, but the earth is spherical. This is ridiculous."
Then, Zhang Shengye pulled Zhang Hao and flew to the roof, pointed in the distance and said: "Look, from what you can see, is the earth curved?
If the earth is spherical, then when we look at houses in the distance, we should only be able to see the roofs, not the entire house.
Okay, stop making trouble."
Zhang Shengye flew away, leaving only Zhang Hao messy in the wind.
What Zhang Shengye said makes sense. But Zhang Shengye did not consider this: the world is very big, but people are very small, and they are insignificant. Using the limit method, what the human eye can see, the limited earth, is indeed flat.
!
As for the farther distance, it is difficult to see clearly due to the obstruction of air, dust, water vapor, etc.
Because this planet is so big, it has hindered people's exploration of the earth.
Also, if this world wasn't so big, with the abilities of cultivators, the facts would have been discovered long ago.
"It's so... interesting!" Zhang Hao sighed helplessly, but did not spit out the curse words after all. After a moment of silence, he flew down to the roof and paid his respects to his mother.
Zhang's mother is a typical family woman who rarely shows up in public; she spends most of her time practicing. She is under pressure.
Zhang Shengde has reached the peak of his golden elixir and is about to reach the Nascent Soul stage, which means a life of thousands of years.
She was afraid that while Zhang Shengde was in high spirits, she would be old.
Therefore, Zhang Hao rarely saw his mother. She spent most of her time practicing.
Zhang Hao hurriedly said hello and left.
When he came to the door, he looked at his father's caravan leaving and sighed leisurely.
In the world of cultivation, there are also worries about life span.
After going back to the bedroom to practice for a while, he swallowed a Xiaolingyuan Pill to suppress his cultivation and consolidate his foundation, 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'. The rotor has four rows at the front and back, a total of 16 windmill blades, and is surrounded by a wind formation.
The wind formation generates wind force, which in turn drives the rotor to rotate.
The power is not small, two low-level spiritual stones can produce almost the power of an ordinary strong horse; but two spiritual stones can only last less than an hour.
Zhang Hao nodded, very satisfied with this breakthrough progress. Although this machine is very crude, the bearings are not ball bearings, but hand-polished iron rings with butter. As for fluids, aerodynamics, blade design, etc.,
Not at all.
But it still means a lot.
This was the first 'mechanical prime mover'.
The previous blower could only blow air, but could not do anything except blow air.
But now, it is a real machine that can output power.
Zhang Hao gave chief designer Huang Mingshan a generous reward. 10 Xiaolingyuan Pills!
The Xiaoling Yuan Pill is not as valuable as the Foundation Establishment Pill; as an elixir that can purify the true energy of practitioners in the Qi refining period and consolidate the foundation, it has great market demand and is cheaper than the Foundation Establishment Pill.
As for the remaining six people, Zhang Hao also rewarded one or two Xiaolingyuan Pills 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 created a machine with almost no practical value. The reward was even greater than the original reward for producing the windmill!
Zhang Hao did not care about everyone's reaction, but started to cheat. He began to instruct everyone on how to design an inner blade rotor.
Cheating is not the same as robbing the seedlings to encourage growth; there will be some research and some failures. Just like spiritual practice, the foundation must be solid!
This is a huge project, an internal vane rotor machine with a wide range of applications in another world.
Aviation engines are one of the pinnacles; steam turbines and gas turbines that drive generators are also one of the pinnacles; 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 steam 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.
In addition, many industrial-grade 100,000-ton and million-ton compressors, high-pressure pumps, etc. also use internal vane rotors.
Zhang Hao also 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.
After receiving the reward, Huang Mingshan and others were equally excited. Everyone devoted themselves to study and research with 12% enthusiasm. Time slipped away quietly, but no one was tired - Peiyuan Pill was supplied in batches.
The leaves, under Zhang Hao's guidance, began to change little by little.
The rotor begins to become slender, and the blades become fine and delicate.
The outer shell of the machine also began to change. High-pressure cylinders, medium-pressure cylinders, and low-pressure cylinders appeared.
The wind formation and the fire formation are used together. 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.
Mathematics, physics and other knowledge have also been developed. Knowledge has progressed through research and practice.
Unknowingly, it has already been a few days later...
…………
It is said that when Zhang Hao started to improve the machinery, Zhang Shengde was called over by the city lord.
After the meeting, the city lord asked directly with a straight face: "Zhang Shengde, you have done such a big thing!"
This mawei-like talk could not scare Lao Zhang - he was just startled by his son's "spherical world" this morning.
Therefore, the old Zhang Youyou said: "City Lord, Youdao is everyone's responsibility for the rise and fall of the country. I can't bear the chaos in the Black Iron Market, nor can I bear the pain of ordinary people. The Zhang family just did what they could.
Zhang Shengde is deeply honored that such small things can catch the eyes of the city lord."
City Lord: Did I praise you just now? What kind of ears do you have?
However, as the saying goes, don't hit someone with a smiling face. Seeing Zhang Shengde being so humble, the city owner's vanity was satisfied. A smile immediately bloomed on his face.
"Master Zhang, I am very strange about this Black Iron Guild. How did you come up with 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.
In the final analysis, it is because we are not united. The other party can negotiate prices one by one.
Therefore, we must unite together and take the initiative in pricing.
We will also be committed to the advancement of black iron technology and provide the country with more high-quality and cheap black iron!
In addition, the guild has many functions, which can stabilize the price of black iron, control the depreciation of black iron coins, and benefit ordinary people as well as small and medium-sized families and businesses.
It can also uniformly dispatch resources to further reduce black iron production costs.
The most important thing is that we can unite and say ‘no’ to foreign countries!”
