There was nothing to say all night. The next morning, after checking his condition, Wu Weiyi asked Mo Zhai to prepare a cart. The two of them came to the valley again.

When it comes to this indigenous cart, its wheels are strong, but they are extremely awkward at the shaft sleeves, which is quite inconvenient to rotate. In addition, it is also a mountain road, so Mo Di only pushed for a while and was exhausted and breathless.

When they arrived at the place, they saw the dazzling array of herbs all over the mountains, but they had to pick some urgently needed by the men. There were other uncommon but seemed extremely useful, but Wu Weiyi had to stare blankly, saying that it was a pity.

Mo Zhai only heard his brother sighing repeatedly. He was good at observing his words and expressions and saw through his thoughts at a glance:

"Brother, are you feeling sorry for not bringing more herbs to return?"

After hearing this, Wu Weiyi couldn't help but smile bitterly:

"Ha, the one who knows me is indeed the virtuous brother!"

Mo Zhai was very happy to receive this praise and continued:

"Brother, if we can make a better car, wouldn't it be convenient to solve it?"

Wu Weiyi squatted down, looked at the cart in front of him, and recalled the hardships he had just gone. Just imagine that if he really used this cart to return with herbs, let alone return to the village, even if he returned to the earthen kiln where they live, it would probably take some trouble...

"But now... just this cart, how can we make a better one?"

Mo Zhai and Wu Weiyi were both in deep thought for a moment. They were both smart and wise, and the other was well-informed, which was perfect. As long as they could imagine, there would be nothing they could not create.

Mo Zhai suddenly slapped his forehead and said excitedly again:

"Hey?! Brother, wouldn't it be more convenient to build a larger pair of wheel bones?

Wu Weiyi nodded first, then shook his head, looking unanimous:

"The bigger the wheels, of course, are more stable, but... the bigger the wheels, the bigger the torque. If you push them, it will be more laborious than it is now..."

After hearing this, Mo Zhai carefully checked the nesting points between the horizontal axis and the wheel axle at the bottom of the cart, and tried to twist it:

"Brother, Zhai has also seen many carriages and chariots. He knows that these shafts are all dead knots. It is still acceptable to carry them on the smooth road, but it is extremely inconvenient to walk on the mountain road..."

After hearing this, Wu Weiyi couldn't help but agree. Mo Zhai was really worthy of being a great man in the future. I think at his age, if he was born in modern times, he would be just a young boy with a bad temper. But now Mo Zhai has a meticulous and meticulous way of solving the problem. No wonder he will be able to become a great man in the future.

However, Wu Weiyi knew only these difficulties. However, he could think of many things but could not make them even if he was not using them. For example, this bearing and marble disc, even though it was an extremely ordinary object in modern times, he could not make them now.

I heard Wu Weiyi sighed again there:

"What my brother said is very... If it were in our era, there was indeed a kind of iron hoop, one big and one small, and some round objects were inlaid in the middle. The inner ring was fixed on the bearing shaft with a lock sheath, and the outer ring was firmly on the wheel bone. Pushing the wheel in this way can save a lot of effort! With the big wheel, it is really like walking on the flat ground on the mountain road! Unfortunately, these objects are crazy about now, and they can only be said..."

While listening carefully, Mo Zhai was already building an image in his mind. After Wu Weiyi finished speaking, his eyes lit up and said excitedly:

"Hehe! Although Zhai cannot make the artifacts mentioned by his brother, the principles are consistent. Zhai Xun thought about something, which may be replaced!"

Wu Weiyi was shocked when he heard this. However, he also knew Mo Di's power, so he was also very happy to hear it:

"If this is true, that's really great! Try to do something for you for me..."

Mo Zhai was not polite with Wu Weiyi this time. The two of them immediately began to weave slightly thinner rattans and polished them with a rectangular wood to make a spindle shape. Then they measured them, and took the bamboo and took the small parts of the head, cut out more than ten identical small bamboo rings, and filled them with slightly thinner wooden branches. Then, the dozen or so small bamboo rings were placed around the spindles at both ends. The rattans were wrapped and attached to the outside as a transmission fix. The outer rattan rings were stuffed into the inner wall of the wheels with spindles, and several fixing bolts were laid around them...

After the wheels on both sides were transformed, Mo Zhai was impatient, so he immediately tried it. It turned out to be much easier than before! Seeing this, Wu Weiyi was itchy, so he stepped forward and pushed and pulled it a few times at will, and couldn't help but praise him sincerely:

"Brother! Your method is really good! Oh... Brother Wei had already said that you will definitely achieve great success in the future! It seems that Brother Wei will also be a disciple of you in the future!"

Wu Weiyi was just a joke, but Mo Zhai was confused and couldn't help asking:

"This... must not be done! What does brother mean by this?!"

When Wu Weiyi heard this, who knew that Mo Zhai actually took this half-true joke as real. Haha, he laughed, patted Mo Zhai on the shoulder and said to him:

"Haha, my good brother will definitely have great achievements in the future and will be respected by the world. His fame and achievements can be far above being a brother! In this case, what's wrong with being a good brother as a teacher?"

Mo Zhai Su's eyes looked indifferent:

"Zhai Zi followed his brother and received many graces. He treated Zhai with deep affection and friendship several times to save Zhai. Besides... If it weren't for his brother, Zhai would be just a slave now, but how dare he hope for anything else? Besides, the elder brother is a god, and Zhai is lucky enough to be able to serve his subordinates, so he is already in panic all day long. If it is true as the elder brother said, and if such a master and secondary are not distinguished, then Zhai's destiny is probably unbearable, right?"

"It's not true, my brother is not the case. This is a bad thing! The so-called plan for everything is established, and if it is not planned, it will be abandoned. The ability of a virtuous brother can be said to be dazzling, so how can he hide the clouds? At most, he is just a bridge-building person... It's not worth mentioning."

Mo Zhai looked at a small model object in his hand, but his expression became more and more serious and somewhat depressed:

"Brother, I don't know why what my brother said just now... If Zhai had a mistake, my brother should say it clearly, and Zhai will correct his mistakes. But please don't expel Zhai. Even though Zhai died, he would also like to repay his brother's kindness for his goodwill!"

When Wu Weiyi heard this, he felt that Mo Zhai was talking more and more severely. He knew that he had misunderstood the matter. He deliberately laughed three times and comforted him:

"Haha... I'm too worried. I want to be a good brother, but I still have to get help from you all the way, but what if I do, I'll drive you away? Alas, I'm just thinking, I'm just thinking!..."

After several comforts, Mo Zhai realized that he was really thinking too much. He swept away the haze and became a little more interested. Wu Weiyi asked him to stay here to make a few more spindle devices. Wu Weiyi quickly called the people of the tribe to push the cart together to pick it up.

When Yang Asha arrived at the Medicine Valley together, she saw Mo Zhai fiddling with some interesting objects at first sight! She also looked at him curiously to see what he was fiddling with?

When Mo Zhai saw that it was her coming, he couldn't help but feel nervous, and a hint of redness appeared on his face:

"Ah! It's...Miss Asha. Just look at it... but don't do it..."

Yang Asha heard this, but was quite dissatisfied:

"Why? Are you afraid that this girl will ruin your business? Isn't this girl the kind of casual and frigid person? You are so despised by black charcoal!"

I saw Mo Zhai muttering in a low voice:

"Hey?! Isn't it...?"

Although Mo Zhai's voice was small, Yang Asha, who was standing beside him, could hear clearly and couldn't help but say:

"Hei Charcoal! You!... Humph! If you say this, that girl will be rude!"

As Asha said, she was about to reach out to snatch the artifacts from Mo Zhai's hand. Mo Zhai hurriedly dodged aside... The two of them chased each other, but they were so unhappy. When Ke Erxiayi saw that they were so inappropriate, she shouted loudly:

"Asha! Don't mess around! If you mess around again, go back with me!"

When Yang Asha heard his father Hao's rage, she immediately stopped her hand, stuffed the object back to Mo Zhai who followed her, and pouted her mouth and hummed:

"Hmph! Black Charcoal! For the sake of my father, I will let you go this time. When I return to the village, I will feel good about you!"

After hearing this, Mo Zhai was not afraid at all. He was lucky to have a strange face with Asha...

After picking the medicine back, Wu Weiyi saw that there was nothing else at the moment, and Du Yu, Bi Mo and the others were patrolling the patients, decorating the medicine and applying the medicine, and applying the medicine, so they were very busy. They wanted to go and take the lead.

"Yu'er, can we leave here after tomorrow?"

Du Yu was pounding medicine at this time, and he smelled that Wu Lang was coming, so he slowed down his skills:

"Haha, the reason should be OK. Wulang, how have you picked the herbs?"

Wu Weiyi came to Du Yu and said with a smile:

"According to Yu'er's wishes, the herbs I picked were hung on the sunny slope. Now everything is going well, and it's enough to live tomorrow..."

After the past two days of care, Ke Erzhenxi's injuries had healed 80% or 90%. When he saw Wu Weiyi and Du Yu so close, he couldn't help but sigh again. Although he knew in his heart that these two people were interested in each other, he could not do anything. However, whenever he saw this, he was still jealous.

"Sister Yu, come and have some water."

Ke Erzhen came with a bowl of clear water in suit. Du Yu thanked him and reached out to take it, but he didn't want to drink it, but just put it aside. Wu Weiyi knew that Du Yu felt the water here was difficult and difficult to swallow. So he had an idea and asked her:

"By the way! Yu'er, do you want to drink this tasteless water?"

Before Du Yu could answer, Ke Erzhenxi hurriedly replied:

"Hmph! It's so light, then you'll change it?"
Chapter completed!
