Lin Feng grabbed Sun Cuo, who was so busy that he didn't even care about raising his head, and dragged him to a place that was not so noisy.

Sun Cuo was a little unhappy at the beginning. Although the man left, his eyes kept looking at the stove with hot flames, and he was muttering: "My strange weapon is almost finished!"

Lin Feng couldn't help but secretly admire him. Isn't it just because of his obsession and concentration that do technical work? Lin Feng gently patted the soil stuck on Sun Cuo*'s shoulder and said, "Sharpening a knife will not delay chopping wood. Brother Sun, did I ask you to consider using the waterfall's hydraulic power a few days ago? Are you clueless?"

"This... I have thought about water mills and water drainage, but it feels not practical." Sun Cuo scratched his messy hair and said in embarrassment.

As early as the Western Han Dynasty, water pestles appeared in China. They were first mainly used to process grain, but later developed into pulp, crushed ore and other uses. The principle of water pestles is mainly caused by the impulse vertical water wheel of the water flow, and the short horizontal wood on the shaft twitches the tip of the pestle, which prompts the pestle head to fall and pound.

As for the water drain, the connecting rod is driven by a water wheel to promote the blower, which is considered a smelting blower driven by hydraulic power. In the early years of the Eastern Han Dynasty, Du Shi, the prefect of Nanyang, invented a tool to use hydraulic power to activate the bellows, namely the famous Du Shi water drainage, which was more than 1,000 years earlier than the emergence of similar machinery in Europe.

Lin Feng was a little surprised and asked, "Why?" Water mills and water discharge have been used for many years. It shouldn't be such a problem.

"I have seen these before, and I feel that they are slow, have low strength, and are difficult to control. I think the water drainage and blowing are as useful as the bellows you fiddled out!" Sun Cuo thought for a while and said.

This is true. The piston bellows are an invention that surpasses the water drainage. Lin Feng lowered his head and thought for a while, found a branch, and drew it underground. Lin Feng changed it back and forth for a while, looked up and said to Sun Chou: "Brother Sun, come and take a look."

Sun Cuo took a lantern from the side and came over and saw Lin Feng drawing three strange things underground. The first one was a long stick with a circle of gear-shaped objects in the middle and a circle of large fan blades at the end; the second one was a hammer-like thing, but a square hole at the tail handle; the third one was very similar to a strange object folded by a five-numbus weapon.

Seeing Sun Cuo's puzzled eyes, Lin Feng no longer kept it a secret and explained one by one: "The first is to make you a long iron rod, with a square column shape on one side, an iron gear is added in the middle, and wooden blades are installed at the tail of the other side. The water from the waterfall hits the blades, causing the iron rod and gear to rotate at a constant speed. The second is to fix a set of hammers at the front end of the iron rod, and use the rotation of the iron rod to drive the hammers to rotate and hit continuously, and use this force to hit unformed weapons. As for the strength and rhythm you mentioned, we can consider making hammers of different lengths and sizes to control them."

"The idea is indeed good, but there will be a tilt angle problem after the hammer." Sun Cuo frowned and pinched his chin with his hands.

"That's a small problem. The hammer head can be made based on actual measurements to create a hammer head with a certain slope on the hammer surface, or find a way to control the forged weapon to maintain a certain angle." Lin Feng replied.

"When the hammer is swung down, it will always be a big circle every time. Where will the weapons to be forged be placed?" Sun Cuo continued to ask.

"This is a big problem. My consideration is to set up an iron platform with wheels next to it, and a dedicated person is responsible for mastering the time and angle of the iron platform pushing." Lin Feng was also a headache. This requires strong control over the people who push the iron platform, but he is suffering from the fact that there are no professional mechanical talents around him now! It seems that in the talent swing ceremony, you must find a few.

"Well, I'll think about it carefully and try to cast a few with a fan. If not, test it first! What is the third one?" Sun Cuo touched his head and pointed at the third strange thing.

"This is equipped with an iron rod. The two mesh with other gears in the middle to drive such a crank push rod to push back and forth in the straight direction. While forging the weapons, use hydraulic power to blow the bellows, so that the person who blows the air can be freed." Lin Feng explained.

"It's a good idea to kill two birds with one stone!" Sun Cuo said.

Lin Feng stood up from the ground, patted Sun Cuo on the shoulder, and said, "I just provided an idea. I have to worry Brother Sun to test it more in detail."

"No problem! If not, let them go back to their parents' home again and throw them back into the stove and refine them again!" Sun Cuo grinned. Perhaps because of the hope of getting rid of the fate of swinging the sledgehammer from then on, Sun Cuo, who was in a very relaxed mood, actually made a joke.

Lin Feng was also amused by his rare humor.

In fact, there are many details that need to be liberated in Lin Feng's so-called invention, but they cannot be solved temporarily due to the limitations of this era. For example, there is no accurate measurement ruler and precise control lathe, set hammers, and installed gears may be stranded due to meshing problems.

Lin Feng shook his head, put these problems before he had professional talents and then worked hard to solve them. Then he asked: "Brother Sun, has the iron ore started to be detected?"

"Well, I have digged there a few times on a daily basis. If I dig one or two feet down, I can see black and gray iron ore, which seems to have a certain magnetic properties, but I am very worried. I am not very good at how to mine iron ore, how to screen, and how to purify it!" Sun Cuo said worriedly.

It seems that the iron ore here is mainly magnetite, and the ore can be screened by magnetic separation, which is very convenient to process; but the magnetite structure is relatively fine and has a poor reduction ability. However, Lin Feng seems to be able to look at Baoshan and return empty-handed now.

Alas, all kinds of professional talents have become the biggest bottleneck problem for their next expansion of development! Lin Feng sighed in his heart, but it was not revealed on the surface. He said to Sun Chou: "This way, on the one hand, we try to dig a part of it in a small range first. On the other hand, when you go to buy iron, you can secretly ask if there are any experts in mining and handling ore. If it really doesn't work, we can only recruit people with high salaries!"

"Well, let's do it like this. Okay, it's a bit late. I can't even open your eyes anymore. Go and rest." Sun Cuo looked at Lin Feng and comforted him.

It would be fine if Sun Cuo didn't say it. When he said it, Lin Feng felt his head heavy. After this long day, he was about to reach his physical limit. So he greeted Sun Cuo and walked back along the almost invisible path.

Sun Cuo took two steps, handed the lantern in his hand to Lin Feng, and patted Lin Feng on the shoulder.
