Lin Jiang's body froze, all along, Li Yi was not dissatisfied with what he made, and it was the first time that Li Yi denied it like this time.

"Young Master, is there a problem?"

"What do you say, you're a little different from the drawings I gave you, aren't you?"

Li Yi frowned.

"Young master, this is just a sample carport, so there is no carport, and it will be right after installing the carport."

"That's not right, after my car is made, it is pulled by people, not by horses, and your wheels and handrails are not right."

"Pulled for someone?" Lin Jiang frowned, he had some impressions, it seemed that Li Yi had said something the day before yesterday, but he didn't care, his supervisor thought it was still a horse-drawn carriage, but he didn't expect the problem to be here again.

"This is impossible, young master, according to your design, this car will be very difficult to make, ordinary people can't pull it at all, even if it can be pulled, the speed is a lot worse."

"Is it that serious?"

Li Yi's face gradually became heavy, he took it for granted, and he also knew that the key to the rickshaw was three parts, load-bearing springs, rubber tires and ball bearings. These three, there are no first two, once the car runs, the slightest bump, the car will vibrate strongly, making the person sitting on it very uncomfortable. Li Yi's original intention was to put more effort into the saddle, try to make it soft and comfortable, and now the newly built cement road in the city can completely solve this problem.

As for the ball bearing, it is definitely a good thing to save effort, but with the current technology, this thing can't be made at all, Li Yi thought that without this thing, even if it is bad, it is not much worse, it is a big deal to use more strength, anyway, the most important thing that people now lack is strength. I didn't expect Lin Jiang to say it so seriously.

"I really can't help it? What if lubricating oil is used? ”

"This ......" Lin Jiang hesitated, although they have studied the lubricating effect of this thing, but the specific effect, they don't know the bottom in their hearts. Master, I haven't tried this yet, but even if I could, oil is so precious, it's a bit of a waste to use it here, right? ”

Li Yi frowned tightly, what Lin Jiang said was not unreasonable, no matter what era, oil is absolutely rare, and using oil on it is not a waste, but it is definitely worth the loss.

After thinking about it for a long time, Li Yi didn't have a clue, and finally smiled bitterly, he simply didn't want to think about it, and left professional things to professional people.

"Uncle Lin, in this way, let's try it first, don't use oil first, you first make a complete one to try the effect, and then we will find a way to improve it."

Saying that, Li Yi first said the basic characteristics of the rickshaw, this time he said it in detail, even more detailed than the drawings, accurate to every small part, Li Yi didn't dare to be careless, lest he be making a four-like. After explaining the structure of the rickshaw, Li Yi said the structure of the ball bearing again, although the ball can't be made by the current means, but it can also provide Lin Jiang with some ideas, what if it collides with some whimsical ideas? Li Yi never underestimated the wisdom of the ancients.

He and Lin Jiang have been discussing for nearly an hour, and some of Li Yi's fresh ideas have given Lin Jiang a lot of inspiration, just like ball bearings, although he also knows that this thing is very difficult to make, but this ingenious design makes him amazed. Not to mention other things that Li Yi proposed, such as roller bearings, gear transmission mechanisms, and hydraulic mechanisms that Li Yi just mentioned, especially hydraulic mechanisms, although Li Yi only mentioned them, but Lin Jiang could hear the huge functions in them, but Li Yi didn't say much, and he didn't dare to ask more, like this kind of confidential ability, Li Yi can say that it is already a great favor, if he asks it, it will be his ignorance.

An hour later, Li Yi left, although Lin Jiang was eager to devote himself to the study immediately, but he still seriously sent Li Yi away, the more he contacted Li Yi, the more he found Li Yi's unfathomable, every time he met Li Yi, he could learn a lot, and he admired Li Yi more and more, until now, Lin Jiang was basically dead set on Li Yi, and he would no longer have the slightest doubt about Li Yi's ability.

Farewell to Lin Jiang, Li Yi also has some understanding, he suddenly found one thing, that is, for such a long time, he only cares about the layout of the big picture, but ignores some basic foundations, that is, education, he now suddenly found that if some things in later generations are taken to ancient times in advance, it will also be a huge treasure, just like today's hydraulic system, the reason why he didn't say it was not that he wouldn't, but that he couldn't, this thing looks simple, but there are a lot of things to say in it, and you can't play this without a solid theoretical foundation. Li Yi was thinking that if he sorted out some knowledge of physics, chemistry, and mathematics in later generations and passed them on to the ancients, there would be a great collision between ancient and modern, maybe there would be a lot of unexpected gains.

The more I thought about it, the more excited Li Yi became, and some of the ideas from a while ago coincided with this, Li Yi finally made up his mind and did it.

When Li Yi came back to his senses, he found that he had actually arrived at the crossroads, walked straight home, and turned right into Dongshi.

"Well, why don't we go to the East Market and have a look?" Li Yi asked.

"Hmph, does my brother remember us? I thought you forgot about us! ”

Wu Meiniang pouted and said dissatisfied.

Li Yi was stunned for a moment, and then lost his laughter, in the morning, he patronized and discussed with Lin Jiang, and then ignored these three, no wonder this little girl was picky.

"Hahaha, it's all my fault, my brother confessed his mistake to Mei Niang, Mei Niang has a lot, how about forgiving the little one?"

Li Yi said with a smile.

When Wu Meiniang heard this, her little face suddenly couldn't hold back, her eyes smiled like crescents, and there was still a trace of resentment. "Well, let's get rid of it, don't take it as an example!"

"Hahaha, little girl." Li Yi rubbed Wu Meiniang's head and laughed heartily.

has been in contact with Wu Meiniang for a long time, Li Yi gradually accepted this little Lori who was a little cautious and a little arrogant, and gradually ignored Wu Zetian's murderous name, in fact, the young Wu Meiniang is definitely a cute existence, although there are some small calculations, but it is all a manifestation of Wu Meiniang's cleverness, which is understandable. What is commendable is that the current Wu Meiniang is very good at taking into account the feelings of others, and there is no unscrupulous means in history at all, Li Yi believes that as long as the guidance is good, Wu Meiniang will definitely not go down the old road.

Playing with Wu Meiniang for a while, of course, Wu Shun was not left behind, this girl belongs to the sultry type, and her temperament is a little indifferent, especially after Li Yi has no worries around her, this temperament is becoming more and more obvious, although there is less fun and human touch, but Li Yi doesn't want to change anything, as long as it is not a crooked way, then let him go, everyone has their own way, forcibly meddling, but it is not beautiful.
