Zhang Feng meant.
He wanted to make a pure steel axle.
Zhang Feng knew the power of the waterwheel.
But this axle had to be replaced almost once a year.
Below the waterfall, the impact of the water falling down from the mountain was far greater than the resistance of the water in the gentle river.
But at this time, seeing Cheng Chumo so confident, Zhang Feng didn't want to dampen his spirits, so he had to remind him.
Yuyao and Jingshu carried a basket of fish and followed Zhang Feng to the balcony on the second floor of the villa. They sat by the small stove, watching Zhang Feng roasting fish while watching hundreds of men lifting the waterwheel.
Although the two women blushed and blushed, such a spectacular and manly scene was rare.
The waterwheel was made of ordinary materials. Because of the rush, the carvings and decorations on it were almost omitted.
But even so.
It took more than two hours for them to get the waterwheel into the water.
Then it was the big base.
The base was easy to get.
It was nothing more than getting some stone strips that had been chiseled and flattened by stonemasons. Then they dismantled the waterwheel and put it on bit by bit.
Zhang Feng also admired these people's perseverance. Without any external help, they could actually set up this five-meter-high waterwheel.
And they didn't know what method they used to firmly integrate it with the stone platform that had been laid out in the water before.
At this time. In everyone's expectation, the waterwheel began to turn.
With the force of the water. ,
It slowly became faster and faster.
And everyone looked at the waterwheel carefully. ,
When the water wheel had started to spin perfectly, everyone began to shout like children in the water.
They shouted from afar, "Feng, how is it? What do you think of this thing? "
Zhang Feng was a little speechless.
But he still nodded.
He got up and looked at everyone, raised the wine glass in his hand, and shouted at the same time, "Good job!"
"Wow —!"
In an instant.
Cheng Chumo and the others cheered again.
And most importantly.
It was the circulation system of the entire waterwheel.
The entire water wheel and water tank.
A total of seven water wheels of different sizes were used.
There were also countless water troughs that circled around every house in the villa area and the dormitory area. ,
In the end, it returned to the lake because of the power of the waterwheel.
Only by completing all of this.
Only then would it be considered the true end.
Zhang Feng could not wait any longer.
Once the water wheel starts moving, the water wheel will start moving.
The matter was almost set in stone. As for how long he could maintain it, that would depend on the abilities of these fellows.
If Li Qian, Du Gou, Ma Zhou and the others were to do this, Zhang Feng knew that with their intelligence, they would definitely do a better job.
However, Zhang Feng didn't want them to come. Instead, he chose Cheng Chumo and the other uncouth men and Qian Xiang.
Qian Xuan 'er's shrewd calculation ability had already stunned everyone.
Li Gang and the old Elementary Scholar even announced that they had accepted him as their last disciple.
This time, it was like a bolt out of the blue for everyone.
Two great scholars had accepted a disciple as their last disciple.
This was simply a rare knowledge of numbers.
These were not important.
The important thing was that without Qian Xuan's idea and calculation ability, Zhang Feng estimated that this group of iron fools would not be able to come up with this thing even if they were given a year. ,
The appearance of Qian Xuan also stimulated these fellows.
Usually, when they were studying physics and dynamics, these fellows were either doing this or that. However, during this period, Zhang Feng found that this group of fellows, instead of jumping around, directly went to do things in silence.
He even heard that they often woke up Du Dabing and the others in the middle of the night to ask questions from books.
Therefore, after hearing this matter, Zhang Feng was really completely relieved.
Dynamics was not something that could be achieved with a simple water wheel. ,
Zhang Feng smiled.
Then, he shouted at Shiva who was standing at the side, "Shiva, go, scrape some white stuff on the wall of the latrine for me. Also, go to the kiln where the lime is burned and get some charcoal …"
Zhang Feng listed out in detail the things needed to make gunpowder.
Shiva was a little confused.
But he still obeyed the order and went.
After Shiva left, Jingshu frowned and asked, "What do you want the things in the latrine for …?"
"And that saltpeter, I remember that only the Ministry of Works seems to have it. It seems that it is very rare among the people. What do you want it for? "
Zhang Feng smiled and said, "Didn't you hear the conversation between Lao Li and I in the living room downstairs just now?"
The two girls shook their heads in confusion.
Zhang Feng heard this and instantly stopped talking.
After pondering for a while, he looked at the setting sun hanging in the col of the Qinling Mountains not far away and said, "That is something that can make mankind take a big step forward!"
Jingshu was stunned.
She looked at Zhang Feng in confusion.
Seeing that she was not joking at this time, he sighed slightly and said, "I don't understand."
"Gunpowder is the ammunition used by cannons."
"I don't understand, can you say something that I can understand?"
"Ah! The weather is so good today! "
"…"
