Although it was a bit discouraged, Wang Lang still didn't plan to give up just now. He planned to look for it for another two days. If he still didn't have any, he could only find a piece of wood and just go there.

The remaining two wheels have been processed, and many wooden boards used to make the carriage have been sawed and neatly placed together.

Now the last axle is left unsolved. As long as there is an axle, the world's first real car can be made. He secretly prayed to God, hoping that he could successfully find the tree he wanted in the next few days.

I don’t know if it was his prayer that had worked, or if the Emperor of Heaven lived up to his hard work, after searching for two consecutive days without success, on the third day, one kilometer away from the tribe, Wang Lang finally found a relatively hard tree.

Wang Lang didn't know what the tree was called. The tree was not thick, which was seven or eight meters tall and the thickness of the legs. The most important thing was that the wood was very hard, and only the bronze axe cut down left shallow traces.

Seeing this effect, Wang Lang knew that his good luck had come, so that people could remember the appearance of this tree and start looking for other similar trees nearby.

Not long after, dozens of such trees were found not far away, but they all had different thicknesses. The thickest diameter even reached fifty centimeters, and the thinner one was only about ten centimeters.

It was too thick and difficult to process. Wang Lang chose several of the trees with diameters of about ten centimeters for people to cut down. Although the tree was very thin, it was no less difficult than cutting down the big trees that made wheels. After cutting one tree, the axe even broke out.

When cleaning the branches, Wang Lang discovered that the fruits of this tree were quite unique. The fruits mixed in the leaves grew in bunches and looked a bit like lentils. Wang Lang did not have the spirit of dedication of Shennong tasting hundreds of herbs, and he did not dare to try such unknown things casually.

People found this tree at noon, and it was almost dusk. It took five or six hours to cut down three trees and broke two axes. You can imagine how hard the tree is.

For safety reasons, Wang Lang decided to return to the tribe while it was not dark. With these three trees, it was enough to make four or five axles.

The seven or eight-meter-long tree trunk was very heavy. Three or four people carried a tree and slowly moved towards the head. It took a long kilometer to finish it. When they returned to the tribe, it was completely dark.

The people who stayed in the tribe saw that Wang Lang and the others had not come back yet, everyone was very worried and lit many torches and looked at the direction when people left.

It was not until I saw a few familiar figures appearing in the night that people felt completely relieved.

After returning to the tribe, the people who fought against the wood all the way were already exhausted and sweating. After drinking a few large bowls of water, they recovered a little.

"Class leader, why did you come back so late? If Kong Er hadn't stopped you, I would have ridden the deer to find you." The bark said with some complaint.

Wang Lang smiled awkwardly and said, "Kong Er is right to stop you. The night is too dangerous. This time it is my reason. The tree is too hard and has delayed a lot of time, which makes you worry."

Tree Bark curled her lips and said, "If something happened to the clan leader, if Huo comes back, he will have to beat me to death."

Wang Lang chuckled and said, "What can I do? I am not made of mud. With our ability, ordinary beasts can't do anything to me."

The bark was about to refute a few more words, and Wang Lang waved his hand and said, "Let's have dinner first. The tribesmen have been tired for a day and have been hungry."

The bark sighed. He didn't want Wang Lang to take risks, but Wang Lang's stubborn personality made him helpless. He shook his head and walked over to let the women prepare food.

After resting for a night, Wang Lang began to prepare for the production of a vehicle the next day.

All the materials for making the vehicle are ready, and the rest is to splice these parts together.

The carriage is undoubtedly simple. Considering the ability of the wheels to withstand the carriage, Wang Lang did not make the carriage very wide, and it was only about 1.5 meters wide. Even for such a carriage, he was worried that the wheels could withstand it when carrying cargo, but no matter how small it was, it would have no practical value.

In order not to repeat the useless work, Wang Lang planned to make a try first, arranged some people to make the carriage, and he asked some people to process the axle part.

The extremely hard wood was peeled off the bark, and the length was slightly wider than the carriage with a saw, and everyone used a chisel to make a shape similar to the holes in the wheel.

Because the wood is hard, the processing process is extremely slow. After half a day, the hand holding the chisel was numb and the axle was completed.

Wang Lang asked someone to install the wheels on the axle. Due to the limitations of technology and tools, the wheels looked a little shaking, which is inevitable. This problem is easy to solve. Just find some wood chips to kill the exposed gap.

Since the wheels in operation are easy to fall off, Wang Lang found a piece of charcoal and drew a line at the intersection of the outside of the wheel and the axle. He planned to set a wedge in this place to prevent the wheel from falling.

After doing this, everyone took off the wheels and started chiseling them at the position where Wang Lang drew with charcoal.

The processing of the axle is about to be completed. Wang Lang handed over the remaining work to others and walked aside to check the progress of the car.

The carriage was made very smoothly, with wood boards connected by wooden blocks and copper nails, and it looked like an uncovered wooden box.

The wood on the shaft has been selected, and two pieces of wood more than two meters long have been processed into a rectangular rectangle with a thick back and a thin front, and are quietly placed aside.

Seeing that the carriage was basically completed, Wang Lang smiled with satisfaction. The last part was the parts connecting the carriage and the axle. Since it was wood grinding, ordinary wood might break if it grind a few times. In order to increase the service life of the vehicle, the harder the material used, the better. Wang Lang planned to make this thing with the wood of the axle.

However, the trees cut back are relatively thin and cannot meet the requirements. They can only wait until tomorrow to cut down another tree and come back.

Not long after, Kong Yi came over and told Wang Lang that the axle had been processed. Wang Lang's eyes lit up and he followed Kong Yi to check.

I checked the holes in the wedge, nodded with satisfaction, asked everyone to install the wheels, staple them with wood chips in the gap, and then staple the wedges that prevent the wheels from falling off into the axle.
Chapter completed!
