Although Wang Jiu'er had some resentment in her heart before, but now that she listened to Li Yong's love words, those resentments in her heart dissipated.

"Even if you have a conscience, it's not in vain that I come here every day to wait for you, and I have prepared a gift for you!"

Wang Jiu'er said with joy, and Li Yong was surprised.

"Huh? Got me a gift? ”

Wang Jiu'er smiled elegantly and confidently.

"Yes, a gift, a gift that will definitely surprise you!"

A gift that surprised him? What gift would surprise him? With Li Yong's current wealth and power and insight beyond the times, there are really not many gifts in this world that can surprise him, so Li Yong does not have great expectations for Wang Jiu'er's expectations, but Wang Jiu'er can take the initiative to prepare gifts for him, he is actually very happy in his heart, and Wang Jiu'er must have put a lot of thought into it, Li Yong said with a smile.

"Gifts? What gift? ”

Wang Jiuer said with a smile.

"Guess what!"

Why do women like to let men guess? This made Li Yong feel very embarrassed, where can he guess this? As Wang Jiu'er, if you want to give a gift, it will definitely not be a common gift, right? Gold and jade antique calligraphy and painting? Or is it something made by Wang Jiu'er herself? Li Yong groaned.

"Could it be a hand-embroidered purse?"

Wang Jiu'er smiled and said with a smile.

"I would like to give you a hand-embroidered purse, but do you dare to wear it? Aren't you afraid that Changle will be unhappy? ”

Li Yong couldn't help but laugh dryly when he heard this.

"What's not to dare to wear?"

But this is true, since he got married, the purse he has worn has been embroidered by Changle himself, just like a woman declaring her sovereignty, Wang Jiu'er couldn't help but light up when she heard it, and said with a smile.

"That's what you said, then I'll really embroider a purse for you when I go back?"

The words are all said, will Li Yong still admit it? Li Yong nodded and smiled.

"Okay, then I'm looking forward to it."

Wang Jiu'er said with a smile.

"However, the gift I prepared this time is not a purse, but something else, something that you have been longing for."

Li Yong was very surprised when he heard this.

"What do I want?"

Now Li Yong himself is a little confused, now that he is rich and powerful, he is famous, what else is there that he wants? Wang Jiu'er nodded.

"Ah, I remember you mentioned it several times, and it took a lot of effort for me to get it."

How many times have you been in front of Wang Jiu'er? Li Yong looked stunned, and had no impression at all, did he mention any gifts he wanted in front of Wang Jiu'er? Li Yong wondered.

"What kind of gift is it?"

Seeing Li Yong's somewhat dazed expression, Wang Jiu'er herself was stunned, she suddenly had a bad premonition in her heart, could it be that Li Yong just said it casually and didn't care at all, right? Although she herself spent some effort on this gift, but it took a lot of manpower and material resources to find this gift back, if Li Yong didn't care at all, then she would really want to cry without tears.

"Didn't you say you wanted to find rubber? Is it a rubber tree? After cutting it with a knife, it will come out with white juice? ”

Wang Jiu'er asked a little nervously, it turned out to be rubber? Li Yong couldn't help but suddenly realize when he heard it, it turned out that rubber! He did mention the matter of rubber more than once in front of Wang Jiuer, it is not easy to find rubber, and it will definitely pay a lot of manpower and material resources, which shows that Wang Jiuer is really very attentive to giving him a gift that surprises him, Li Yong said with a smile.

"It's rubber! I really want to find rubber, but I don't think it's easy to find it, and I want to wait until I have time to find it. ”

Seeing that Li Yong's face was full of joy, Wang Jiu'er was finally relieved, what she was most afraid of was that she had to trouble finding rubber, but Li Yong was not surprised at all, if this was the case, even if she paid more, it was useless, it was all in vain, Wang Jiu'er nodded.

"I've found it."

Li Yong said with emotion.

"It's not easy to find, it takes a lot of manpower and material resources, it's really troublesome for you!"

Wang Jiu'er smiled sweetly.

"As long as it's really useful, it's worth it no matter how much it costs! Does it really work? ”

She was still a little unsure whether rubber was really useful, she had indeed heard Li Yong say it before, but when she didn't say it just now, Li Yong had no impression at all, she was afraid that Li Yong pretended to be useful in order to comfort her, Li Yong nodded again and again with great certainty.

"Useful useful, really useful! Very useful! ”

Wang Jiu'er asked with some satisfaction and some curiosity.

"Does it really work? What's the use? ”

"The usefulness of rubber is great, for example, with rubber, I can build a car that can go forward without pulling a horse or being pushed by someone!"

Wang Jiu'er asked with a look of surprise when she heard this.

"No need to pull? A car that can walk on its own? ”

Li Yong nodded and said: "Yes, you don't need to pull, you don't need to push, the car can go by itself, you only need someone to grasp the direction!" ”

Wang Jiu'er's mouth opened slightly, her face was incredible, if someone else said this, she would think that the other party was bragging, but it was Li Yong who said this, can it be fake?

"You don't need to pull, you don't have to push, the car can go by itself, so it must be immortal, right?"

Wang Jiu'er's excited little face flushed and asked, it must be immortal! She couldn't think of any other possibilities than immortal magic! Could it be that rubber is actually an immortal material that can perform immortal magic? Such a precious immortal material must be very rare, rare in the world, will it be found so easily? Although it took a lot of manpower and material resources, it was insignificant compared to the materials of the Immortal Family, so Wang Jiu'er suddenly began to doubt at this moment, could it be that he was wrong? In fact, it is not the rubber that Li Yong is looking for at all, but just the rubber that Li Yong is looking for? Li Yong said with a smile.

"What kind of immortal arts, that's called science and technology!"

Is it a kind of immortal art called science and technology? Wang Jiu'er's eyes were full of admiration when she looked at Li Yong, this man knows immortal arts!

"I can't be wrong, right? Could that not be rubber? Just like? ”

Wang Jiu'er was a little unconfident, if she found the wrong one, it would be too big, Li Yong said with a smile.

"Isn't it just a cut and white juice comes out? You can't go wrong! ”

"The people I sent brought back two truckloads of rubber blocks, one of which was left in the clan land, and the other car I brought to Chang'an, you can see if it is the rubber you are looking for!"

Wang Jiuer replied, in the end, what she found was not the rubber that Li Yong was looking for, as long as Li Yong took a look at what she brought back, she would definitely be able to tell it, Wang Jiuer sent people to find rubber trees, and it took a lot of manpower and material resources, and naturally it was inevitable to use the people at home, so the two cars of rubber blocks brought back were left by the family, although they didn't know what the rubber blocks were for, but since this was what Li Yong wanted to get, it means that the rubber blocks must have great value. If it weren't for their complete belief in Li Yong's ability, they would not have agreed to Wang Jiu'er mobilizing so many manpower and material resources to find rubber trees, they firmly believed that since Li Yong wanted to get rubber, rubber must be a priceless treasure! Therefore, they even thought about leaving the two cars of rubber blocks, but there was a problem in front of them, they didn't know what the rubber blocks were for, because the rubber blocks didn't look beautiful, and they weren't a treasure worth appreciating and playing, if they wanted to know what the rubber blocks were for, there was only one way, that is, to give Li Yong a car of rubber blocks, and then see what these rubber blocks were for, Li Yong was very surprised, he didn't expect Wang Jiuer to not only find the rubber tree, And he also brought back a cart of rubber blocks directly.

"Brought back a cart of rubber blocks? And in Chang'an? That's great! ”

Li Yong was pleasantly surprised, Wang Jiu'er was still a little embarrassed after speaking, after all, the person she sent brought back two carts of rubber blocks, but the family left one cart.

"My family had to leave a cart to see what the rubber could be used for, so I only brought one cart with me."

However, Li Yong didn't care at all that Taiyuan Wang's left a car, in fact, rubber is not a rare thing, not to mention that Taiyuan Wang's people don't know how to use rubber, but he hopes that the industry can develop in Datang, Li Yong said with a smile.

"It's okay, they want to stay, rubber has many uses, for example, it can be made into tires, now it can't be made into inflatable, it should be good to make it solid, it must be more comfortable and durable than wooden wheels."

Wang Jiu'er was confused when she heard it, didn't she say that rubber can be made into her own car? How do you make a wheel again? Is it more comfortable and durable? Could it be that if you make a wheel, it will move on its own?

"The point is, I don't know if it's rubber or not!"

Wang Jiu'er said a little apprehensively.

"If it's rubber, won't you find out if it's rubber?"

Li Yong said with a smile.

"Now?"

Wang Jiu'er asked in some surprise.

"If it's okay, now is it!"

Li Yong said with a smile, Wang Jiu'er was both happy and a little disappointed when she heard it, the loss was because she still wanted to get along with Li Yong more and be more affectionate, happy because the gift she prepared really made Li Yong very happy and cared about it, Wang Jiu'er tidied up her dress, and then walked downstairs side by side with Li Yong, attracting a lot of people's attention along the way, and there were many people in the library who recognized Wang Jiu'er, after all, Wang Jiu'er often came to the library, and was also one of the main builders of the library, and the contribution in front of the library was on the list. One is the prince of Tang Rongfu and the princess of Changle, and the other is the eldest lady of the Taiyuan Wang family, walking side by side in the library, it must be because of the library! It must be like this, after all, both of them have made contributions to the transformation of the library, Li Yong originally planned to go to the firearms superintendent, but now he has already left the matter of going to the firearms superintendent behind, full of rubber, in fact, the steam engine has been very mature in the Xishan Workshop and the Huating County Workshop, after all, the principle of the steam engine is still relatively simple, Li Yong also understands this, but what makes him worried is that what the piston uses to achieve the sealing effect, if there is rubber, then this problem will be solved, Isn't it to make rubber seals, Li Yong is still very confident in this, sulfur is easy to find, carbon black can collect vegetable oil, pine branches burning black smoke to make do, stearic acid can be used vegetable oil or wax instead of try, zinc oxide to find zinc ore with zinc carbonate preparation, as for the accelerator or something, you don't have to think about it, isn't it the speed of vulcanization is slow, it doesn't matter, and there are no high requirements to make a simple sealing ring, Li Yong feels that only these superficial means are enough, Li Yong rode a horse and walked beside Wang Jiu'er's carriage and kept thinking about it, but he was eager to try it in his heart, the steam engine, that was the steam engine that triggered the first industrial revolution! Not to mention anything else, just used in trains and ships will have a huge impact on this era, using a steam engine to make a car, think about Li Yong feel very excited, in the previous life, the car has long been very common, nothing rare, but now, Li Yong is very nostalgic for the car of later generations, although he is not able to make an internal combustion engine now, but using steam to make a car can also be enjoyable! And he is not playing blindly, because although the steam car is unreliable, it is impossible to promote, but the steam train can be promoted, along the way, Wang Jiuer from time to time lifted the curtain to look out, to be precise, he was looking at Li Yong, but Li Yong has not turned his head to look at her, along the way, Li Yong frowned and pondered from time to time, and smirked twice from time to time, so that Wang Jiuer couldn't help but look at it intently, and said that serious men are the best-looking, Li Yong's serious thinking appearance, she felt very charming, and it was almost there, Li Yong seemed to have forgotten that she was by her side, and Wang Jiu'er asked with a slight pout.

"What are you thinking?"

Li Yong heard the voice, turned his head to look at her, and said with a smile.

"I'm thinking about how to make a car that can walk on its own!"

"Did you figure it out?"

Wang Jiu'er asked curiously, Li Yong nodded and smiled.

"It's generally understood, but I still need to try, and I should be able to make it soon!"

If a person doesn't know the principle of the steam engine, it may take several years or even decades to invent and improve the steam engine, if a person already understands the principle of the steam engine and knows the mature plan, then it only takes half an hour to figure out how to make a steam engine. It must be very beautiful, it must be immortal, and maybe it will exude golden light, Wang Jiu'er tried hard to imagine in her heart.

"When we arrive, the rubber block is in the storeroom inside the manor."

The carriage drove into the manor, and Li Yong also entered the manor with him, Wang Jiu'er glanced up at Li Yong, and her heart suddenly became very nervous, she secretly prayed in her heart, but don't make a mistake! Li Yong even thought about how to make a car that could walk by himself without pulling or pushing, if the thing he brought back was not rubber, then how disappointed Li Yong would be!
