Hearing that Yang Shubao brought a new invention, Jill really brightened his eyes.

Every time he shows others his invention, this kind of thing is too many times to make him a little boring, he needs to brainstorm, he needs to invent communication.

So when Yang Shubao took out the printed design book, he couldn't wait to stretch out his hand: "Let me see, what have you invented? It must be a great thing, I have confidence in you, brother, you have a clever brain that can invent good things." ”

Yang Shubao handed him the design book and the sample of the water purification clay pot, and after he got the clay pot, he looked left and right: "What is this? Don't say it, let me guess, rainwater collector?"

"No, it's too small to collect a lot of rainwater. Then I guess it's an anti-urine splash tool? I once designed a similar one, men are always dishonest when peeing, they like to play with tools to cause urine to spill outside the urine bucket to pollute the environment, and there are also urine bifurcations that they can't control, it's really hard to say when it comes to urine bifurcation, Brother Yang, do you have any urine bifurcation?"

Yang Shubao smiled bitterly: "No." ”

Jill sighed, "There is a guy in our tribe who has a very bifurcated urine, and he can divide into several strands of ...... when he pees."

"Did he put a shower on the chickens?"

"Haha, his thing does look like a shower - uh, aren't we talking about inventions? Why are we talking about bifurcation again?"

Lao Yang was powerless to complain, Jill was nonsensical, and when he was with him, he had to be prepared to explode his mind.

He explained: "The topic of urine bifurcation was brought up by you, and this tool has nothing to do with urine......

"It has nothing to do with urine? It's not a urine splash prevention tool?"

"It's not. ”

"Then let me guess again. Jill rubbed his temples and began to brainstorm.

Yang Shubao estimated that he couldn't guess the use of this water purification clay pot, so he took the initiative to introduce: "This is a filter cartridge, which is used to filter drinking water. I see that your tribe still drinks groundwater from wells, which is not disinfected or sterilized, and such water is at risk of contamination and is not suitable for direct drinking. ”

Jill suddenly said, "I guessed that this tool is used to catch water, and when you pour water into it, it will filter out pollutants and the like in the water, right?"

Yang Shubao smiled and nodded, unable to answer.

It's a guess, he said it's a tool for filtering drinking water.

Jill was quite complacent: "I actually guessed correctly, the rainwater collector and the anti-urine splash tool, this clay pot can also collect rainwater for drinking water, right?"

Yang Shubao said euphemistically: "It is better to drink less rainwater, its pollution is more serious, I am afraid that the filtering effect of this clay pot is still too bad for rainwater, and it is not very effective." ”

Jill said nonchalantly, "We all drink rainwater directly, and we can't drink filtered rainwater yet?"

Yang Shubao thought that there was a reason why the Zulu people had a short lifespan.

He said, "Jill, I am going to spread this tool in your tribe, let's build an earthen kiln in your tribe to burn this tool for your people, what do you think?"

Jill is happy: "I think it's good, it's a good thing for our tribe to improve the quality of life. ”

He called his father, Edgar Allan Poe Sr., who was preparing to preside over the sacrifice, and showed him the water purification pot.

The elder Edgar Allan Poe wore glasses and was apparently also an educated man of culture.

He is much more stable than his son, and he has a much longer vision, and he is very happy to understand the purpose of the clay pot.

The problem of drinking water pollution has always been a big problem he wants to solve, he once bought a water purifier to use in the tribe, but the tribe has too many people, and the efficiency of everyone waiting in front of a water purifier is too low, and the Zulu people are acute, and they don't wait after a few times.

Buying more water purifiers can solve the efficiency problem, but the tribe doesn't have so much extra money for this.

The water purification clay pot is a weakened version and a simple version of the water purifier, which can be arranged by every household, as long as they can burn the water purifier by building an earthen kiln in their tribe, it is really how much it is going to be.

Yang Shubao said: "When the time comes, you will not only use it yourself, but you can also give it away or sell it to other people who need it." ”

Edgar Allan Poe Sr. reached out and clapped his fist on his chest and saluted him, realizing the difference the technology would bring to the tribe.

After successfully promoting the technology to the Tata tribe, Yang Shubao showed his success to Song Chao, Lin Lin and others in the WeChat group.

He didn't think it was too difficult to do that.

Seeing the photos he took, the international students left messages to congratulate, some sent WeChat emojis, and some posted love packs......

Lao Yang put away his mobile phone to participate in the celebration and helped Zhang Jinjie to take tourists together.

One tourist put down his camera and asked, "What's going on at their tribe's celebration?"

Yang Shubao said: "Well, dance around the campfire and eat and drink. ”

The Zulu banquets he attended were all such events, so I guess the same will be true for this celebration.

Zhang Jinjie inquired in advance, and he said loudly: "Don't get separated, you must be together, there is a special grand sacrifice tonight, and the scale is quite large." But there is danger, after all, the grassland is not safe at night, so everyone must be together. ”

There are men in the tribe who kill pigs and sheep with knives, and a group of children gather around to watch the excitement.

The Zulu people were very savage, or rather very strong, in killing sacrificial animals, and they brought a machete directly, and then one of the strongest black men came and beheaded it.

A pig was tied, and the black man lifted the knife with both hands.

"With a knife, the pig's head must fall off in its entirety, otherwise it is considered ominous. Jill said.

The number of onlookers gradually increased, not only children, but also people who had nothing to do.

So the black man got up to the point, he spat in his hand, grabbed the knife, raised it above his head, and played.

A large knife spun above his head, and the one-and-a-half-meter machete turned so amazingly that people kept screaming.

Looking at the children and women with amazed faces, Yang Shubao was surprised: "Haven't they usually seen this kind of scene?"

Jill said, "Do you think anyone can come and perform the sacrificial sword ceremony? This is a cow man we have invited from other tribes, a cow man who can cut off the head of a hippopotamus with a single sword!"

Yang Shubao asked, "Can you really cut off the head of a hippopotamus with a single sword?"

Jill sneered, "Maybe, but it can cut off a bull's head with a single sword!"

"Awesome!"

As soon as Yang Shubao finished praising him, the big knife that was being played with in a circle suddenly flew out without stability.

Fly to the crowd!

The exclamations turned to screams, and the crowd scrambled backwards.

The big black man who threw the knife followed with an arrow step, and dragged the big knife back with a tug of his wrist.

It turned out that he didn't know when he put the holster on the handle of the knife on his wrist, and the flying knife just now was just to scare people.

A group of people were really scared enough, this knife is more than one and a half meters long, and it weighs twenty or thirty kilograms.

Yang Shubao was quite sympathetic to the pig, it was ready to die, but the knife came and went for a long time, which made it psychologically suffer from old sins.
