The effect of the punishment was significant, with those few examples of being tied up in front of them, and in the next training, these recruits were 100% energetic and were in a state of high tension at all times.

Wang Lang stood on the city wall, watching the training of these recruits, and he saw all the previous punishments in his eyes.

He knew that for these people who had just escaped from the savages, no preaching was as direct as the discipline of a club.

Seeing that the training of the recruits was gradually on the right track, Wang Lang did not pay attention to it, he was very satisfied with the current training method.

Soon after Wang Lang walked down the city wall, a person hurriedly ran over from the inner city.

"Chief, the wheels are ready." The man said excitedly.

"Oh~" Wang Lang's eyes lit up, and he hurriedly said, "Take me to have a look." ”

The man nodded excitedly and led the way in front of Wang Lang.

When Mu Feng and the others saw Wang Lang coming, they came over to salute Wang Lang.

Wang Lang waved his hand casually, then called Mu Feng over and asked, "Are the wheels ready?" Where is it. ”

Mu Feng replied respectfully, "Chief, the wheels are ready, this is it!" ”

Mu Feng pointed to the two flower wheels on the ground.

Wang Lang stepped forward, and sure enough, he saw two wheels with a diameter of more than one meter neatly stacked together, and the appearance of these wheels was no different from the one he remembered.

The wheels are made of spokes and curved planks, and there is even a layer of copper more than a centimeter thick around the edge of the wheel.

"Yes, put on the axle and I'll see how it goes." Wang Lang said with some excitement.

When Mu Feng heard this, he hurriedly led everyone to assemble the prepared axle and two wheels.

After a busy while, the wheels were assembled.

"Push and walk." Wang Lang said.

Four or five men, after Wang Lang finished speaking, pushed the axle hard, the wheel began to turn, making a squeaky friction sound, this time the axle did not rotate with the wheel, in the process of advancing, these people demonstrated the turning action, the smooth turning process, Wang Lang nodded again and again.

"Chief, what do you think of this wheel?" Mu Feng asked respectfully.

"Very well, in the future, you will do the same and make more vehicles like this." Wang Lang said.

"Rest assured, Chief, after making the first one, the rest of the production will be much easier." Mu Feng said confidently.

"How long do you think it will take to make one?" Wang Lang asked.

"If the firewood is ready, it will take three days to make one." Mu Feng replied.

"So fast?" Wang Lang looked at Mu Feng in some surprise.

Mu Feng smiled and said, "Originally, it couldn't be so fast, but I still got your reminder." ”

"My reminder?" Wang Lang said with some doubts.

Mu Feng nodded and said: "Before, you divided the labor and cooperation of the clansmen who smelted copper, each person was responsible for the fixed part, plus the compass you did before, I was inspired by this, I made a wooden plank, this wooden board can measure the length of each thing, with this thing, we people, as long as each person is responsible for a part, and then assemble the wheels, it will be fine, which saves a lot of time." ”

Wang Lang looked at Mu Feng suspiciously, the tool that can measure the length is undoubtedly a ruler, but a primitive person can actually do it to this extent, which is really beyond his expectations, and even in his heart, there are some doubts that the young man in front of him is also a traverser, playing a game of pretending to be a pig and eating a tiger with himself here.

But on second thought, this is a bit nonsense, how can there be so many traversers in this world.

"Show me the plank." Wang Lang said.

When Mu Feng heard this, he rummaged through the place where the timber was stacked for a while, and found a rectangular wooden board about thirty centimeters long.

"Chief, this is the plank I made to measure the length." Mu Feng handed the ruler to Wang Lang and said.

Wang Lang looked at this wooden board that had no scale at all, this thing was so simple that it could barely be counted as a ruler.

"Why didn't you put a scale on it?" Wang Lang's eyes were staring at Mu Feng tightly, wanting to see any special expression on his face.

"Scale? What is a Scale? Mu Feng asked with a blank expression.

Looking at Mu Feng's expression carefully, he didn't see any signs of fakeness, he laughed at himself a little, thinking that if Mu Feng was a traverser, then this guy's acting skills had reached the level of an actor.

Wang Lang took the ruler and said, "Have you seen the name of the tribe!" ”

Mu Feng nodded and said, "I've seen it, it's really a magical thing, it can measure the multiplicity of things, compared to the leader, my wisdom is as small as a worm." ”

Regarding Mu Feng's compliment, Wang Lang just smiled and said, "Since you have seen the scale, have you ever thought about why I carved so many points on the scale rod." ”

When Mu Feng heard this, he thought for a while, and suddenly realized: "Chief, do you mean that those points are also carved out of this wooden board like a weighing rod to measure the specific length of things?" ”

Wang Lang nodded with satisfaction and said: "That's right, for example, I stipulate that the weight of a copper brick is one catty, and you can also stipulate a length, for example, this plank, you can divide such a long plank into ten or more parts, and each small piece is the most basic length, so that it is more accurate to measure." ”

Mu Feng was extremely excited when he heard this, looking at this plank, he couldn't wait to start making it according to the method taught by Wang Lang, but the other people around him were confused, as if the two were talking about the Book of Heaven.

"Bring me the compass." Wang Lang said.

Mu Feng almost worshipped Wang Lang as a god, and after Wang Lang finished speaking, he hurriedly took the only compass in the tribe.

Wang Lang took the compass and adjusted it to a width of about one centimeter.

Then, under the gaze of Mu Feng and others, nineteen scales were marked on that wooden board with a compass.

"This plank will be used as a ruler in the future, and the distance of each scale, I will make them one centimeter, and the distance of less than a hundred small squares is one meter, and now this ruler has twenty small squares, that is, twenty centimeters, and when measuring things in the future, this ruler will be used as the standard." Wang Lang said slowly.

After handing over this ruler to Mu Feng, Mu Feng couldn't put it down and looked at this simple ruler, in his eyes this is a rare treasure, even the strongest and sharpest weapons of the tribe can't compare to it.

This ruler, as the wooden wind made more and more things, and gradually became a myth, in the legends of later generations, called the first ruler in ancient times as the wooden wind ruler, it is said to have the power to measure the heaven and the earth.
