Although the three girls all expressed their approval of Chen Zhe's ambitious plan, they were inevitably a little nervous.

Dig clay and burn bricks, and then use bricks to build walls - this plan is really too complicated. Can the four of them really do it?

Not to mention other questions, the most obvious question is how Chen Zhe transported a large amount of clay from the mountain?

Wall tiles are different from pottery. He and Yan'er can move them down by dividing work and working together. If you want to burn bricks and build a wall, you need a large amount of clay. There are probably hundreds or thousands of pounds of clay. Chen Zhe can't take the girls to carry the clay baskets one by one with the vines woven from the vines, right?

While searching for thorns, the girls began to talk.

"Sister, sister Yan'er, how do you think Chen Zhe is planning to transport the clay down the mountain?" Xiao Qiao asked.

"Carry it down with a rattan basket. Are there some baskets in the camp woven with rattan?" Da Qiao guessed.

"What?" Xiao Qiao was so scared that she was so scared that she was lost. "Just use the vine basket to carry clay? The clay is so heavy... can we carry it... and the vine basket is so rough. What if the skin is scratched?"

Da Qiao shrugged: "If you can't carry it, just recite it less at a time. You can't let Chen Zhe carry it all alone, right?"

At this time, Yan'er smiled and said, "Don't worry, Brother Chen will definitely have a better solution. We won't let us carry clay directly in the vine basket."

"Really?" Xiao Qiao asked half-believingly, "he really has a way to solve the problem of carrying clay?"

"Sure, there must be." Yan'er said confidently.

...

at the same time.

On the other side of the camp.

Chen Zhe was walking in the woods with a blood-drinking knife, looking for a tree with a thick trunk.

Soon a mature rubber tree came into his eyes, and the trunk diameter of the tree reached about 1.3 meters.

"This tree is growing well and upright..."

Chen Zhe nodded with satisfaction, then waved the blood-drinking knife and chopped directly onto the tree trunk.

Clever, Clever, Clever...

After a hard slash, Chen Zhe finally successfully cut off the big tree in the waist. Then he selected the thickest part of the trunk and cut out a complete piece of wood along the annual rings.

The wood cut out in this way is the cross-section of the trunk of the tree, and it is also a natural circle with a diameter of 1.3 meters. Chen Zhe carefully cut off its bark along the edge, and then repair the unsmooth and regular parts to a slightly rounder, and a round wood is ready.

Looking at the round wood in his hand, an ancient means of transportation - a unicycle trolley appeared in Chen Zhe's mind.

This round piece of wood can be used as the wheels of a wheelbarrow.

After having the wheel, Chen Zhe next took a square hole in the center of the wheel with sharp gravel.

This hole is used to penetrate the axle. The square shaft hole allows the wheel to take force and rotate with the axle to avoid slipping in place.

Next is to make the axle.

Chen Zhe used a long and strong branch to cut the middle part into a square shape that fits the shaft hole, and the sides were rounded, which became a beautiful and durable axle.

The axle and wheels are all completed, and the next thing to do is the frame.

The structure of the frame is more complicated and requires the splicing of several pieces of wood. However, with the experience of making hand-crank spinning wheels last time, it became more familiar to assemble the frame.

The bottom of the frame is connected to the wheel and the axle, and a pair of handles similar to horns are left above. In addition, on the front side of the handle and directly above the wheel, a wooden board needs to be placed to transport goods.

When Chen Zhe patiently assembled all these parts together, a simple wheelbarrow was presented to him.

But like the handicrafts he made in the past, this wheelbarrow is just a bad product.

Chen Zhe didn't need to make a tool of excellent quality at all. He just needed to make a product that could be recognized by the item upgrade system.

Leave the remaining tasks to the system.

While Yan'er and the Qiao sisters were not nearby, Chen Zhe stared at the wheelbarrow and began to upgrade.

The system quickly identified the items in front of him.

[Article detected - a wheelbarrow that falls apart after touching it.]

"Damn..." Chen Zhe was speechless for a moment, and silently complained in his heart, "If you touch it, you will fall apart? Is the wheelbarrow I made this time so bad?"

Then the system asked:

【Will you use 100 popularity points to upgrade items?】

"certainly."

Chen Zhe made a choice without hesitation, and the wheelbarrow changed after that.

[A wheelbarrow that falls apart after touching] - Upgrade - [A wheelbarrow that is not useful].

“Continue to upgrade!”

[A wheelbarrow that is not useful] - Upgrade - [A simple handmade wheelbarrow].

After two consecutive upgrades, Chen Zhe helped the wheelbarrow up and took a look. He saw that the wooden splicing structure on the car was already quite solid and the wheels were rotating very smoothly.

Such a hand-made unicycle is more than enough to transport clay.

"Very good, that's fine. If you upgrade, it will be a mistake."

Chen Zhe thought about it, so he pushed the wheelbarrow back silently to the camp.

At this time, on the camp.

Yan'er and the Qiao sisters have used dry thorns to replenish the space left by the burning of the fence.

At this time, Yan'er and Da Qiao were busy organizing lunch, while Xiao Qiao was boiling water and reeling shreds.

Suddenly, a "creaking" sound came from outside the camp. The three girls all looked in the direction where the sound came. Then they saw Chen Zhe walking in from outside the door with a wheelbarrow. This unique wheelbarrow attracted the attention of the three girls.

"Wow! This is... this is a trolley?" Da Qiao asked in surprise.

"Brother Chen, you built a trolley with your own hands?" Yan'er was even more overjoyed.

When my child was a child, my grandfather used this kind of trolley when he was doing farm work in the field. During the autumn harvest season, my grandfather would push such a car to send the corn from the field home.

Chen Zhe smiled lightly and pushed the cart into the yard.

At this moment, he felt that this simple and practical trolley was so cool. Even if it was Ferrari and Lamborghini were far inferior to its style.

Because on this island, trolleys are an important tool that can improve their productivity and are material guarantees that can directly change their lives.

With a trolley, the clay on the mountain can be transported to the camp at the foot of the mountain.

The three girls had already put down their work and ran to Chen Zhe happily.

They lowered their heads and couldn't let go of their hands, rubbing the trolleys that Chen Zhe made (upgraded) by himself.

"Is this wheel made directly from the cross-section of the tree trunk?" Da Qiao exclaimed, "Chen Zhe, you are indeed very creative."

"The frame is made so strong, it's like it's polished with a machine." Yan'er said sincerely.

"That's great. With this trolley, we don't have to carry clay with a vine basket on our backs. This will save a lot of effort." Xiao Qiao said happily.
Chapter completed!
