I am a primitive

At this time, Han Cheng still doesn't know what happened after the Feng Tribe and Lin Feng Tribe, because of the old primitive man's god assist, if he knows, he will be very happy. Kung fu here feels that it is hard to be a dad...

The next day Han Cheng got up, and after another family quarrel, Han Cheng took a piece of paper to find Hei Wa.

Heiwa was still there making mud.

Most people will develop occupational diseases after doing one thing for a long time. For example, Heiwa now feels weak all day if he doesn't touch the mud for a day.

However, it is precisely because of his occupational disease-like love that he is able to make pottery and clay-related molds so well.

"Son of God."

When Hei Wa saw Han Cheng coming, she raised her head and greeted with a smile. After seeing Han Cheng holding a piece of paper in her hand, she immediately dropped the mud in her hand. She didn't even have time to wash her hands. Excitedly, he leaned over and aimed straight at the piece of paper in Han Cheng's hand.

Seeing Hei Wa's appearance, Han Cheng couldn't help laughing and cursing: "Don't look at it eagerly, this is a new thing that needs to be forged."

As he spoke, he unfolded the paper in his hand for Hei Wa to read.

Hei Wa, who was pointed out by Han Cheng, just smiled, her eyes were still fixed on the paper that Han Cheng was opening, with an expression of excitement on her face.

Now this guy is like Lame, he has almost reached the point where he can't stand the cold in the tribe, he always wants to make something new and something that hasn't been done before, and in the tribe, the most creative person is the son of God, from time to time You can come up with something that they can't think of at all and let them do it, so as soon as you see Han Cheng coming over with the blueprint, no matter if it's lame or Hei Wa, they will subconsciously get excited.

The paper unfolded, and there were three circular things drawn on it.

One is placed flat, one is erected, and the other is displayed behind.

These three pictures actually depict the same thing, which is the gong.

As the weather gets colder day by day, autumn is getting stronger and stronger, and winter is approaching, Han Cheng started to prepare for the first Winter Games of the Qingque Tribe.

Gong is one of the things that needs to be prepared.

Just a drum, Han Cheng still felt that it was not lively enough to highlight the momentum of the sports meeting.

So he thought of the gong, which is as famous as the drum.

The sound of gongs and drums is not for nothing.

Moreover, after getting out the gong, it is not only used in the sports meeting, but can also be extended to the defense of the tribe.

With the construction of the tribe's outer wall, the entire tribe has been greatly expanded. With a larger area, the clappers made of wood are somewhat insufficient.

The clapper is made of wood after all, no matter how strong the force is and no matter how suitable the wood is, the sound it can produce is still limited, far inferior to that of a gong.

In addition to city defense, it can also be extended to the army later.

Beating the drums to march, and beating gold to withdraw troops, these are the two most simple and easy-to-understand orders.

After Han Cheng opened the blueprint, Hei Wa's eyes were fixed on it without blinking. After getting enough of his eye addiction, he quickly ran to the side to wash his hands.

After scrubbing his hands clean and wiping his clothes vigorously, he took the blueprint from Han Cheng and looked at it carefully with a serious expression, immersed in it.

After a while like this, Hei Wa moved his eyes away, and Han Cheng began to tell Hei Wa the function of the gong, how to use it, the desired effect, etc...

It is impossible not to tell these things. After all, what is drawn on paper is just a pattern, not the real thing. For Hei Wa, who has never been exposed to such things as gongs before, it is very important to understand the effects of gongs. It is necessary.

On the way of talking between Han Cheng and Hei Wa, Hei Wa would ask some questions from time to time, and Han Cheng also explained to Hei Wa in as much detail as possible based on his own understanding of Tonggong.

After going on like this for a little while, Hei Wa stopped asking, and sat there without saying a word, thinking.

In the afternoon, Hei Wa, who was in deep thought, started to move, mixed the mud with his own hands, and then made the mold of the gong...

Han Cheng quietly left the pottery workshop when Hei Wa started to meditate. He knew that he had basically finished the matter on the gong, and the rest was Hei Wa's business.

Han Cheng was not idle either. After coming out of the pottery workshop, he found a small copper saw and went to the bamboo pole forest with it.

Find a suitable bamboo in the bamboo pole forest, and then cut it neatly from the root with a copper saw.

Originally, this is not a difficult task, but if there are two more pandas who will hug your legs from time to time and never let go, then everything will be another matter.

After a while, after being robbed of three bamboos, Han Cheng managed to escape from the bamboo forest with a bamboo thicker than his thumb.

After returning to the courtyard, use a copper saw to cut off a section of about [-] centimeters. First, use a tool to break through the bamboo joints inside and smooth them as much as possible. Then use a ruler to point a few points outside the bamboo. Click it, and then find a small hand press drill, and start drilling at the topmost point.

However, the hole hadn't been drilled yet, and Han Chengcheng stopped his movements helplessly.

Bamboo is different from wood. The texture of bamboo is clearer, and it is precisely because of this that bamboo can be broken into thin bamboo strips.

But now, it was this feature that caused Han Cheng to run into trouble.

The trouble is that when drilling holes in bamboo, there will inevitably be some small bamboo strips on the surface around the holes, making the bamboo uneven.

But what Han Cheng wanted to achieve was that the surroundings of the holes were flat, and the holes drilled were just like those drilled out of wood.

Another two hand press drills were used on the discarded bamboo pipes. After trying to drill a few holes, Han Cheng gave up the idea of ​​using hand press drills to drill holes he wanted on the bamboo. .

Rubbing his chin and thinking for a while, Han Cheng found a copper stick of appropriate thickness, lit a fire and heated it inside, took it out and pressed it on the bamboo tube, and at the same time pressed down with his hand with appropriate strength, and gently Turn lightly.

When the fiery copper rod and bamboo came into contact, green smoke rose immediately, and after a while, black powder overflowed from the inside, and the copper rod also fell into the bamboo tube.

After a while, the temperature of the copper rod dropped and the progress slowed down. Han Chengcheng put the copper rod back into the fire and burned it. After heating up, he took it out and aimed it at the small shallow pit that was burned out on the bamboo pipe, and continued to repeat the previous action.

After doing this three times, the bamboo was burnt through, and Han Cheng removed the copper stick, and a round hole appeared on the bamboo tube, with smooth edges, unlike a hand-pressed drill.

Han Cheng showed joy.

Immediately, I used a copper saw to cut off a bamboo about [-] centimeters long, and opened up the other two bamboo joints, leaving the one near the top of one end.

Then continue to use a ruler to compare marks on it, and after burning the copper stick red, burn holes one by one against the marks.

"God, what is this?"

Wu didn't know when he came over and watched intently. He didn't ask until Han Cheng had burned all the holes.

"This is a flute, a bamboo flute, which can make a nice sound."

Han Cheng found a piece of waste linen, squatted there and carefully wiped the black ash at the entrance of the cave bit by bit, and answered Wu's question aloud.

"A nice voice? Is it better than my sister sitting on the bow?"

Bai Xuemei, who was holding Xiao Xing'er, came over at some point, and answered Han Cheng's words curiously.

Han Cheng's face twitched, the silly woman remembered that her sister was at the bow of the boat.

"I'll blow it off and you'll know."

Han Cheng said with a smile, and at the same time peeled off a layer of film from the inside of a split bamboo, wet it with a little water and stuck it on the second hole, so that a bamboo flute can be considered completely finished up.

With one hand inside and one hand outside, Han Cheng separated his fingers to press the remaining hole, brought the bamboo flute horizontally to his mouth, slightly pursed his mouth, and tried to blow air into the first hole.
