Never, adults have thought that one day they will be rejected by their own children.

Today, they have experienced the feelings of children when they are rejected.

Look at me, after I glared at you, the men who were successfully persuaded to leave looked at each other and smiled.

"I'm a little envious of Aoki, what should I do?" Wen Shui teased.

Ah Shan, who was also persuaded by the child to leave, patted Wen Shui on the shoulder: "It's okay, you are not the only one who has such thoughts!"

Wen Shui asked with a deeper smile at the corner of his mouth, "What are we doing? Practicing rafting?"

"It is carried by various ministries of the grass marsh, and the grass raft is not important..."

Before the words could be uttered, Ah Shan stopped, and he, who was looking down at the crowd, turned his head to look at Wen Shui.

At the same time, he also thought of the most important thing, Wen Shui, and then he said in a daze: "Sap, if that thing is successful, it will take a lot of sap."

Instead of doing it slowly later, they all hope to do it now.

It is a fact that the brains are not as good as those of the Kusanuma Ministries. With the Kusanuma Ministries, they can avoid a lot of detours. They don’t have so much confidence in themselves. It is what the Kusanuma Ministries taught them and learned at that time. , Looking back, they can do wrong again.

"Let's collect it. If there is enough sap, the child will be able to toss it around." Wen Shui made a decision.

Nodding his head, Ah Shan followed in his footsteps and shouted for someone.

It is enough that there are people from all Kusanuma tribes in the place where the marbles are fired. Hearing that the men are going to collect sap, Ome immediately asked the women from the other two tribes to help.

The crowd was divided into three groups. One group fired marbles, one group collected tree sap, and the other group made rubber cloth.

As Xia Weiwei thought, the slope on the water bank is very suitable. The tree sap poured from top to bottom will slide down naturally without manual assistance, and the surface of the cleaned formwork will not lose the temperature inside, and it will slowly slide down. The tree sap has been maintained in a fluid state under the temperature of the formwork.

"Wei Wei, come and look over here."

Just when Xia Weiwei was quite satisfied with the effect, Xiaochun who was on a high place shouted suddenly, and following her were the children from various departments standing on the uphill.

"The ones here are also gone!"

"The ones here are too!"

"It looks like it's going to flow down!"

The slope angle of the water bank is used to allow the sap to flow downward naturally, but it is also due to this angle that the sap affected by the template temperature is always in a fluid state, so there is no possibility of uniform tiling at all.

After looking at the rubber that flowed to the center of the template, Xia slightly pointed to some people.

"Bring water."

I just fetched water to wash the formwork before, now the water basin is on the side, and after a while, the water Xia Weiwei asked for came.

"Slowly drench, drench all the way."

The sap soaked in cold water will condense, and it will melt when it is heated. No one can imagine what it will look like when the bottom is hot and the top is cold, but they all understand one thing.

Xia Weiwei knew how to do this, but they didn't know how to do it.

The children obediently poured basins of cold water down, and the rubber that touched the cold water immediately solidified, while the fluid ball that hadn't completely dripped out moved more slowly.

Seeing that the resin on the upper edge of the mold began to soften again, Xia Weiwei let the child pour cold water again, this time after watering, she began to tear.

As the temperature of the mold gradually rose, the rubber that was pulled up began to soften again, but Xia Weiwei didn't let people glue it, but just pulled it.

Thinking of less moisture, the finished product will have better toughness, high density, and the rubber cloth will not be damaged so easily. In addition, the softness and hardness of the rubber rope made earlier are quite suitable. She will use this pot of rubber Came according to that ratio.

Unexpectedly, the density was too high, and the temperature of the template was a little higher. This first experiment ended in failure.

However, although things failed, Xia Weiwei also found a technique and found a more suitable thickness.

Boil the pot again to melt the rubber. This time, more water was added, poured into the mold, and the whole mold was covered with no rubber for half a minute. Before the rubber reacted, cold water was poured down. Once the cold water passed, it started Pulling, the rubber solution turned into a rubber cloth in less than 3 minutes before and after.

"It's so soft and easy to play, and it's much more comfortable to the touch than the one just now!"

"This one is successful. If this one is not as good as the previous one, what else can be improved?"

The children chattered while pulling the rubber cloth, Xia Weiwei looked at the rubber in the center which was getting heavier and heavier, but began to frown.

"What else is wrong?" Hei Shi immediately asked after noticing her restrained expression.

Xia slightly pointed to the center of the rubber cloth.

Looking at Heishi pleasingly, he didn't see any problems.

The rubber rope he handled had such a drapey texture, so naturally, looking at the sunken center of the rubber cloth, he certainly didn't think there was anything wrong.

After waiting for 2 minutes before Heishi spoke, Xia Weiwei could only point out the problem, but hearing that the elasticity was too great, Heishi was speechless.

"Big elasticity is not just right, it can be pulled apart if necessary."

Staring at him for a few seconds, Xia Weiwei didn't explain much to him, and just let the children grab the edge of the rubber cloth and pull it.

The original ten-by-ten square cloth immediately became deformed, and when Xia Weiwei let it be folded, the rubber cloth could not shrink at all, and the front part was wrinkled, and the edge was damaged due to the child's too much force.

Now, Heishi dare not say that the rubber cloth with good elasticity is good.

"Then how to solve this problem?"

"How would I know!" Chang Xia was speechless this time.

She also has some common sense. She really doesn't understand how to make the gum less elastic.

Xia Weiwei had no choice, let alone the others. For a while, the atmosphere was a little stagnant.

I still remember Xia Weiwei poking face earlier, Ah Ling couldn't help muttering for a moment: "With such a big battle, I thought you were sure of it!"

Everyone looked at the waste rubber sheet at a loss, the scene was so quiet that a needle could be heard, Ah Ling's not-so-loud sound was comparable to an earthquake at this time.

Almost instantly, the children's eyes fell on her.

The more vain people are, the more sensitive they are, and the disapproval in the children's eyes immediately annoys Ah Ling.

The fate of Xiao Ying's mother and daughter naturally sounded the alarm for Ah Ling, but the only thing that their mother and daughter gave her was to stop antagonizing Xia Weiwei.

In her heart, both Wenbu and Shanbe depended on them, and she always had a sense of superiority in front of them.

This time it makes people look at it like this, how can I feel better.

"Look at me, am I wrong?"

Everyone: "..."

Everyone's increasingly dissatisfied eyes stung Ah Ling.

With a straight face, she took it for granted: "Who is she? Feeling ashamed? Shouldn't you say sorry to us?"
