The air was hot and dry, there was a lot of dust floating in the air, and the ground was covered with iron filings, but none of this could stop everyone's burning gaze.
The surface of the metal object in front of me is still rough, but it has begun to have a streamlined design.
The object is gourd-shaped, one meter in size, and is made of thick iron. There is a large hole (air inlet) in the belly at the back; two low-level spiritual stones are inlaid on the base.
The "gourd" as a whole is composed of more than a dozen 'parts', which are riveted to each other.
The formation patterns arranged by high-grade black iron are drawn from two spiritual stones and submerged inside the gourd.
Huang Mingshan explained to Zhang Shengde and Zhang Shengye: "This is a fan designed using a new mathematical method. This time the fan not only uses the wind formation method, but also the flame formation method.
As the saying goes, "Fire borrows the power of wind, and wind assists fire." When wind and fire cooperate with each other, the efficiency increases by about 4 to 5 times.
In addition, after the combination of wind and fire, a wind roll pattern is formed inside the abdominal cavity of the fan, which can effectively reduce the internal temperature of the fan and ensure the safety of the fan."
Zhang Hao turned around and asked: "What is the design air volume and wind speed?"
"The design air volume is 10 cubic meters per minute and the wind speed is 10 meters per second."
"What about reality?"
"The actual situation has not been measured. Moreover, we don't know how to measure it." Huang Mingshan was a little embarrassed.
"If you don't know how to measure it, just go and research it. I don't believe that you can produce a fan, but you can't measure the air volume of the fan." Zhang Hao did not try to encourage others, but directly said how to measure it. In fact, it is not a simple matter to measure the air volume.
matter.
Measuring air volume requires temperature, pressure, density, etc., but now all of these are blank.
Everything needs to be developed from scratch, little by little.
Of course, during this process, Zhang Hao will provide some necessary guidance as appropriate.
After a short pause, Zhang Hao said again: "Start the fan and check the situation."
Huang Mingshan quickly pressed the spirit stone and activated the formation. Wind began to shoot out from the mouth of the gourd. You could see that the dust suspended in the air was blown and rolled, and the strong wind gradually swept through the entire room.
Zhang Hao put some scraps of paper at the mouth of the gourd and roughly estimated the wind speed through the scraps. Finally, he nodded with satisfaction. "The wind speed is about 9 meters, and the diameter of the air outlet is 8 centimeters. The drawing and the fan data match 90%. Calculate
You are qualified.
Each person receives a bottle of foundation-building pill and goes home to rest.
I have a day off tomorrow and think carefully about what I have learned in the past few days."
Huang Mingshan and others took the elixir and left quickly. Soon only Zhang Hao, Zhang Shengde and Zhang Shengye were left.
Zhang Hao picked up the drawings compiled by Huang Mingshan and others, came to Zhang Shengde and Zhang Shengye, "Dad, second uncle, this is what we have achieved these days."
Zhang Shengde circled around the fan and felt the consumption speed of the spirit stones. He was a little surprised and said, "These two spirit stones are enough to support the operation of the fan for two days.
And the air volume of this fan is much larger than those of current fans."
"Yes. This is the power of 'mathematics'."
"Mathematics?" Zhang Shengde and Zhang Shengye said in unison.
"It's the Sutra I got from Master Mingxu, but we made some improvements and extensions." After a pause, Zhang Hao handed the drawing to Zhang Shengde, "Dad, such a fan has already been
It is enough to replace the bellows.
The windbox occupies a large area, requires frequent maintenance, and requires a lot of manpower; and the windbox can no longer meet our current production needs.
It's time to make a change."
Zhang Shengde weighed the drawings and thought thoughtfully: "How much does it cost to produce such a fan?"
Zhang Hao spread his hands: "I'm not sure at the moment, but all the materials are ready-made, and the cost price is not much higher."
Zhang Shengde thought for a while and suddenly smiled: "Okay, Xiaohao, I will leave the fan production issues to you. It just so happened that the family recently absorbed some craftsmen from the Qian family, so we have enough manpower."
"I don't want craftsmen from the Qian family, I want people who are trustworthy and capable in the family, preferably those who grew up in the family."
"no problem!"
…………
But Huang Mingshan said that he left the mine and ran towards home. From a distance, he saw the faint silhouette in the window.
After knocking on the door, the couple looked at each other silently.
"I'm back." Huang Mingshan said quietly.
"It'll be good to come back." A bright smile broke out on the wife's face. Only her slightly red and swollen eyes showed that the woman had just cried.
At this time, Huang Mingshan's clothes were almost in tatters. After a busy day, especially at the end when he had to smelt, forge, etc., Huang Mingshan seemed to be back to the way he was a few days ago - going home every day.
Dark.
After entering the room, Huang Mingshan took out the porcelain bottle from his arms and said softly: "High-quality foundation-building pill!"
The wife was not moved by the Foundation Building Pill, but held Huang Mingshan's hand.
Huang Mingshan's hands were covered with blisters and burns.
"It's okay!" Huang Mingshan hugged his wife, "From today on, I can say with certainty that our destiny has changed. I misunderstood the young master before, and we are participating in a great thing."
"Yeah. You must be hungry. I still have some food left."
It's midnight, and the family of three is quietly enjoying the warmth.
…………
It was another early morning, and many craftsmen of the Zhang family were crowded.
This morning, everyone is on holiday because Master Zhang Hao wants to select some elites from among the craftsmen.
This caused a huge response.
Zhang Hao may not be aware of it yet, but the seven people he previously selected, including Huang Mingshan, have become living advertisements.
Instead of working, you learn new knowledge and receive generous rewards every day.
This has already made everyone jealous.
Now, is it finally your turn?
"Quiet!" Zhang Hao shouted, and the scene fell silent for an instant.
"The screening rules for this time are those under 20 years old and whose cultivation has reached the fourth level of Qi Refining.
Those with a certain formation and rune foundation will be given priority.
Priority will be given to those with excellent forging skills.
Those who are ingenious or have special skills will be reported and inspected separately.
Finally, 50 people will be selected based on their merit."
Before the words were spoken, many old craftsmen were dissatisfied.
"Why are you making such a fuss!" Zhang Shengye got angry and suppressed the situation as soon as he spoke. "Have you been given too much of a salary increase recently to make you forget about it?
You, come out!"
Zhang Shengye pointed out a craftsman who came out. The craftsman was a little trembling.
Zhang Hao knew this man, he was one of the craftsmen who first forged black iron in front of Zhang Hao.
But Zhang Shengye scolded him sternly: "Zhou Da, let me ask you, how much has your salary increased in the past ten days?"
"That... almost three times more."
"So, how much contribution have you made to the family?"
"Uh... this..." Zhou Da suddenly turned red and couldn't say a word.
Zhang Shengye snorted coldly: "Zhou Da, I've been paying attention to you for several days. You've been a bit lazy recently! I'm telling you, if you don't want to do it anymore, go mining."
Zhou Da suddenly didn't dare to speak. Although he was also a craftsman, his mining salary was obviously lower and his status was lower. The person responsible for forging was a skilled worker.
Zhang Hao quickly recruited 50 people, but Zhang Hao looked at everyone and said calmly: "You have 50 people, and in the end, you can only leave 20 people! So, perform well.
Now start the grouping, each group of 5 people choose their own group leader.
Time, a moment!"
In a short time, 8 groups appeared, with 10 people scattered around, refusing to admit defeat.
"You have been eliminated." Zhang Hao coldly announced the final judgment.
The ten people were stunned immediately.
"I don't like people who don't know how to unite." Zhang Hao said, scanning the crowd, "You are just ordinary people. Only by uniting can you go further."
The ten people began to beg, but Zhang Hao did not let go.
When the ten people finally left, Zhang Hao said to the remaining people: "Come over and look at the drawings, and ask me if you don't understand anything.
Tomorrow, Huang Mingshan and others will come back and explain it to you.
Starting from tomorrow, you will begin to learn to build items according to the drawings, and only the best four groups will be left.
Remember, from now on, you are a group, a group, and what I want to see is the group's achievements, not individual ones."
