There was nothing to say all night, and in the early morning of the next day, after Wu Weiyi checked his condition, he asked Mo Zhai to prepare a board car. Together, they came to the valley again.

Speaking of this indigenous board car, its wheels are also sturdy, but it is extremely jerky at the axle sleeve, which is quite inconvenient to rotate, and it is a mountain road, so Mo Zhai only pushed for a while, and he was already tired and panting.

When they arrived at the place, they saw that the mountains were all over the wilderness, and there were a variety of herbs, but the two of them had to pick some of the servants that were urgently needed. There are some uncommon but seemingly extremely useful, but Wu Weiyi can only stare dryly, even saying that it is a pity.

Mo Zhai could only hear his brother sighing again and again, and he was good at observing words and feelings, and he saw through his thoughts at a glance:

"Brother, are you sorry that you can't bring more herbs back?"

Wu Weiyi listened to it, and couldn't help but smile slightly bitterly:

"Oh, the one who knows me is really none other than 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 inconvenient to solve it?"

Wu Weiyi squatted down, looked at the cart in front of him, and recalled the hardships just now. Imagine if you really use this kind of board to carry the herbs back, let alone go back to the village, even if you return to the earthen kiln where they live now, I am afraid that it will take some trouble......

"But for now...... With only this one car, how can we make a better one? ”

Mo Zhai and Wu Weiyi both fell into deep thought for a while, the two of them, one ingenious and the other knowledgeable, can be said to complement each other. But as long as they could imagine it, there was nothing they could not make.

I saw Mo Zhai suddenly pat his head, and said excitedly:

"Huh?! Brother, wouldn't it be easier to climb up the mountain road if we rebuilt a pair of larger wheel bones? ”

Wu Weiyi first nodded, then shook his head, with a noncommittal look:

"Bigger wheels are better for you, but ...... The bigger the wheels, the greater the torque, and it will be more laborious to push them than they are now......"

Mo Zhai listened, so he carefully checked the nesting place between the horizontal axis and the wheel axle at the bottom of the board car, and tried to twist it again:

"Brother, Zhai has also seen a lot of carriages and carts, and knows that these axes are dead knots. It is okay to carry it on the road on the road, but it is extremely inconvenient to walk on the mountain road......"

Wu Weiyi listened to it, and couldn't help but think deeply. This Mo Zhai really deserves to be the future giant of the Mo family, thinking that at his age, if he was born in modern times, he would still be just a hairy boy who has not dried up. But now Mo Zhai is already thoughtful and has the essentials to solve the problem. It's no wonder that he will be able to achieve great things in the future.

However, Wu Weiyi was also aware of these difficulties. But because of its clumsy use, he could think of many things, but he couldn't make them. For example, this bearing and marble disc, even if they are very common objects in modern times, he can't make them now.

I only heard Wu Weiyi sigh there again:

"What the virtuous brother said is extremely ...... Indeed, in our day, there was a kind of iron hoop, one large and one small, set together, and with some round objects in the middle. The inner ring is fixed to the bearing shaft with a lock sheath, and the outer ring is fixed to the wheel bone. This saves a lot of effort! Supplemented by a large wheel, the bento can really be on the mountain road as if walking on the ground! It's a pity that these objects are now a fantasy, and they can only be just talk......"

While Mo Zhai listened carefully, he was already constructing an image in his mind. When Wu Weiyi finished speaking, his eyes lit up, and he said excitedly:

"Hey, hey! The utensils that my brother said, although Zhai can't make them now, but the principle is the same. Zhai Xun thought about something, maybe it can be replaced! ”

Wu Weiyi couldn't help but be shocked when he heard this. But he also knew how powerful Mo Zhai was, and he was overjoyed when he heard it:

"If that's the case, that's great! You try to do something for your brother......"

Mo Zhai was not polite to Wu Weiyi this time, and the two of them even began to weave a slightly thinner rattan, and polished it with a rectangular wood at both ends to make a spindle shape. Then I measured it, took the small part of the head of the bamboo, cut out more than ten identical small bamboo rings, and filled them with slightly thinner branches. After that, the dozen or so small bamboo rings are placed around the spindles at both ends. And the rattan is wrapped outside as a transmission fixation. The outer rattan ring is stuffed into the inner wall of the wheel with a spindle, and several bolts are laid around it......

When the wheels on both sides are modified, they are completed. Mo Zhai was in a hurry, so he immediately tried it, and sure enough, it was much easier than before! Seeing this, Wu Weiyi's hands were itchy for a while, so he also stepped forward and pushed and pulled a few times at will, and couldn't help but praise from the bottom of his heart:

"Brother Xian! You're really good at it! Ah...... Brother Wei said before, you will definitely have a great achievement in the future! It seems that my brother will also worship you as a teacher in the future! ”

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

"This ...... Never! What does my brother mean by this?! ”

When Wu Weiyi heard it, who knew that this Mo Zhai actually took this half-truth joke seriously, laughed, patted Mo Zhai on the shoulder again, and said to him:

"Haha, the virtuous brother will definitely have a great achievement in the future, and he will be admired by the world, and his fame and achievements can be far above that of being a brother! In this case, why not worship a virtuous brother as a teacher? ”

Mo Zhai was stunned, but he didn't care with a face:

"Zhai Zi followed his brother and received a lot of grace, and his brother also treated Zhai with deep affection and righteousness, and saved Zhai from danger several times. Moreover...... If it weren't for his brother, Zhai would still be just a slave now, but how dare he expect anything else? Besides, the elder brother is a celestial, and Zhai is fortunate to be able to serve by his side, so he is already in fear. If it is really as my brother said, there is no distinction between priority and priority, then Zhai Zhi's destiny is afraid that it will not be able to bear it, right?! ”

"No, no, no, Brother Xian's words are bad! The so-called everything is foreseen, and if it is not prepared, it will be wasted. The ability of a virtuous brother can be described as dazzling, so how can it hide the sun? As a brother, at most, he is just a bridge-builder...... It's not enough to worry about it. ”

Mo Zhai looked at a small model artifact made in his hand, but his expression became more and more solemn, and he was quite depressed:

"Brother, I don't know what the reason for what Brother Fang said...... If Zhai has had it, his brother can say it clearly, and Zhai will change it. But please don't chase Zhai, Zhai is dead, and I wish to repay my brother's kindness! ”

When Wu Weiyi heard this, he only felt that this Mo Zhai was talking more and more seriously, and knew that he was thinking about this matter too much. He deliberately laughed three times and said with relief:

"Haha...... The virtuous brother is too worried, and he wants to be a brother all the way, but he still needs more help from the virtuous brother, but how can it drive you? Alas, I want to be biased, I want to be biased! ……”

After several reliefs, Mo Zhai realized that he was indeed thinking too much. It was a sweep of the haze, and a little bit of interest. Wu Weiyi asked him to stay here and make a few more hinge devices. And Wu Weiyi hurriedly called over, and everyone of the Yu tribe pushed the cart together and came to the medicine valley to pick.

When Yang Asha arrived at the Medicine Valley together, he saw at a glance that Mo Zhai was tinkering with some interesting objects there! He also looked at him with curiosity, to see what he was fiddling with?

And when Mo Zhai saw that she was coming, he couldn't help but feel nervous, and a hint of red appeared on his face:

"Ahh It's Ah ...... Miss Asha. Just take a look...... Don't do it......"

Yang Asha heard this, but she was quite unconvinced:

"Why? Aren't you afraid that this girl will ruin your business? Is this girl the kind of person who is casually frizzy? You black charcoal also looks down on people! ”

I saw Mo Zhai muttering in a slightly playful whisper:

"Hey?! Isn't it still ......? ”

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

"Black charcoal! You! …… Hum! If you say so, then the girl will be welcome! ”

As she spoke, Asha was about to reach out and snatch the artifact in Mo Zhai's hand, but Mo Zhai hurriedly dodged to the side...... The two of you are chasing me, but you are so unhappy. And Ke Yiyi saw that the two of them were so unorthodox, so he shouted loudly:

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

Yang Asha heard her father's angry words, so she immediately withdrew her hand, stuffed the utensils back to Mo Zhai, who was following behind her, and pursed her lips and snorted softly:

"Humph! Black charcoal! For the sake of my father's face, this girl will let you go first this time. When I go back to Yuzhai, this girl feels good with you! ”

Mo Zhai listened, but he was not afraid, and she was fortunate to make a strange face with Asha......

After collecting the medicine and going back, Wu Weiyi saw that there was nothing else to do at the moment, and Du Yu and Bi Mo were making rounds for those patients, decoction of medicine, dressing of medicine, very busy. I just want to go and get a hand.

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

Du Yu was pounding medicine at this time, and when he heard that Wu Lang was coming, he slowed down the kung fu in his hand:

"Hehe, it should be possible. Wu Lang, how did you choose the herbs over there? ”

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

"According to Yu'er's meaning, the herbs picked are hung on the sunny slope. Now that everything is going well, it will be enough to wait for tomorrow......"

And after two days of recuperation, Ke Erzhenxi's injuries on his body have also healed. When he saw Wu Weiyi and Du Yu walking so closely, he couldn't help but sigh again. Although he knew in his heart that the two of them were interested in each other, it was difficult for him to make a difference. But whenever I see this scene, I am still jealous.

"Sister Yu, come, drink some water."

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

"That's right! Yu'er, do you want to drink this tasteless water? ”

Before Du Yu could answer, Ke Erzhenxi hurriedly replied:

"Humph! It's easy to say, so why don't you change your mind? ”
