Chapter 1565

Zhang Feng means.

To get a pure steel axis.

Zhang Feng knows the power of the waterwheel.

But this axis has to be changed almost once a year.

The water falling down from the mountains below the waterfall is far less simple than the resistance suffered in the gentle river.

However, seeing Chumo's vows, Zhang Feng was not happy, so he had to give a hint.

Yuyao and Jingshu came to the balcony on the second floor of the villa with Zhang Feng, carrying a basket of fish. They sat next to the small stove, staring at Zhang Feng's grilled fish and watching the scene of hundreds of men lifting the waterwheel.

Although the two women looked red and shy, such spectacular and manly scenes were also rare.

The waterwheel is commonly made. Because of the rush, the carving and decoration on it are almost free.

But even so.

It took more than an hour to get the waterwheel into the water.

Then there is the big base.

The base is easy to handle.

It's just to get some stone strips that have long been chiseled and leveled by a stonemason, and then dismantle the waterwheel and assemble it bit by bit.

Zhang Feng also admired the perseverance of these people. Without the help of any external force, he was able to set up this water tanker one and a half feet high, that is, five meters high.

And I don't know how to make him firmly combine with the stone platform exposed in the water.

At this time, in the expectation of everyone, the waterwheel creaked and turned.

With the action of water

Slowly faster and faster.

At this time, the crowd also looked at the waterwheel carefully

After the water wheel had rotated perfectly, the people shouted wildly in the water like children.

He shouted at a distance, "Feng Zi, what do you think of this thing?"

Zhang Feng was speechless.

But nodded.

He got up and looked at the crowd, raised his wine glass, and shouted at the same voice, "good job!"

"Oh --!"

moment

Chumo and others cheered again.

And most importantly.

Or the circulation system of the whole waterwheel.,

The whole waterwheel and sink.

A total of seven water tankers, large and small, were used.

And countless water tanks, a large area around every house and dormitory area in the villa area

Finally, it returned to the lake again because of the power of the waterwheel.

Only by completing all this.

It's the real end.

Zhang Feng can't wait.

The waterwheel just moves.

It's almost certain. As for how long he can keep it, it's going to test the ability of these guys.

If Li Qian, Du Gou, Ma Zhou and others came to do this, Zhang Feng knew that with their intelligence, they would certainly do better.

But Zhang Feng didn't want them to come. Instead, he chose Chumo and Qian Chuaner.

Qian Chuaner's shrewd computing power has amazed everyone.

Even Li Gang and the old scholar directly announced that they had accepted him as a closed disciple.

This, this is enough to give everyone a bolt from the blue.

Two great Confucians, take one disciple as the closing disciple.

It's rare to know numbers.

None of this matters.

Importantly, without Qian Chuaner's ideas and computing power, Zhang Feng estimated that even if they were given a year, these iron Han Han could not come up with this thing

The appearance of Qian Chuaner also stimulated these goods.

On weekdays, he studies physics and dynamics. These guys either do this or that one by one, but they don't do it well. But during this time, Zhang Feng found that these guys don't jump any more and go straight to work.

I even heard that I often called Du Dabei and others in the middle of the night to ask questions from books.

Therefore, after hearing this, Zhang Feng was really relieved.

Dynamics is not so simple that it can be done with a waterwheel

Zhang Feng smiled.

Then he shouted to Xiwa standing on one side: "Xiwa, go, scrape some white things on the walls of the thatched house for me, and get some charcoal from the mouth of the lime kiln..."

Zhang Feng carefully listed all the things that made gunpowder.,

Siva was a little confused.

But I took orders.

As soon as Xiwa left, Jingshu frowned and asked, "what do you want from this thatched house... For?"

"And the saltpeter. I remember it seems that only the Ministry of works has it. It seems that there are few people with it. What are you doing with this?"

Zhang Feng said with a smile, "didn't you hear my conversation with Lao Li and their son downstairs in the living room?"

The two women shook their heads in doubt.

Zhang Feng stopped talking when he heard the speech.

After pondering for a while, he looked at the sunset hanging in the Qinling Mountain depression not far away and said, "that's something that can make mankind take a big step forward!"

Jing Shu was stunned.

He glanced at Zhang Feng suspiciously.

Seeing that she didn't mean to joke at this time, she sighed slightly: "I don't understand."

"Gunpowder is the ammunition used by artillery."

"I don't understand. Can you say something I can understand?"

"Ah! It's a nice day today!"
