Empress Changsun got off the back seat with a hint of healthy blush on her face, and she was obviously very satisfied with the ride just now.

Li Shimin couldn't help but praise: "Yes, the bicycle is very good, it's such a good thing! It would be great if my subjects had a bicycle, so it would be much more convenient to travel! It's both labor-saving and fast, and there's no need to feed it!"

Empress Changsun praised: "Boy Su has made good things again. This is a good thing that benefits the country and the people! Boy Su has made a contribution again!"

What's the thing?

Build a bicycle?

With the current level of Datang craftsmanship, even bicycle chains cannot be made, let alone tires!

We need rubber to make tires. Of course, we can find rubber trees, which also have sulfur, but where can we get stearic acid, zinc oxide, carbon black and accelerators?

Su Cheng quickly shook his head and said, "No, no, Your Majesty and the Empress misunderstood. I can't build a bicycle!"

Li Shimin said with a puzzled look: "What? Can't you build it? Then where did this bicycle come from?"

Yes, where did it come from? I have to compile this carefully, and Su Cheng pondered in his heart.

Empress Changsun smiled and said, "It was your master who left it?"

Su Cheng smiled but said nothing. This was what you said by yourself, but I didn't say anything.

Li Shimin immediately looked so angry that he looked so angry: "Look, your master knows you, you don't know? With such a capable master, what have you learned? I'm almost annoyed you!"

Su Cheng was confused. Nine years of compulsory education really won’t teach this!

"It's not that I can't make it, it's mainly because the raw materials are difficult to find." Su Cheng said helplessly.

Li Shimin waved his hand and said, "You said, I will find you whatever you need!"

"Rubber is a milky white rubber produced by rubber trees. It only exists in the south. It also requires stearic acid, zinc oxide, and accelerators. In short, it is very troublesome." Su Cheng explained.

Li Shimin was completely confused. He was quite knowledgeable, but he had never heard of it.

The slap came very quickly, and even though he was as thick-skinned as Li Shimin, he couldn't help but blush.

Empress Changsun said regretfully: "So, there is only this bicycle in the world? It's such a pity."

Su Cheng smiled and said, "It will be done one day, it will only take time, maybe five years, maybe ten years."

Li Shimin couldn't help but raise his eyebrows and his eyes fell on this bicycle. In other words, in the long term, there will be only this bicycle in the world?

Thinking of the cheerful and wonderful time when I rode my bicycle with the queen just now, Li Shimin's eyes suddenly became hot when he looked at the bicycle.

Here, I'm coming. Su Cheng turned his eyes and saw Li Zhi looking at the bicycle. He couldn't help but smile and asked, "King Jin, do you like this bicycle?"

Li Zhi raised his head and nodded sharply, "I like it, I like it!"

"The King of Jin likes this so much, then I'll give this bicycle to you!" Su Cheng said with a smile.

Li Zhi's little face suddenly turned purple and purple, and he almost fainted when he was so excited.

He wanted it very much since he first saw the bicycle. Later, he heard Su Cheng say that he could not build a bicycle, and he was extremely disappointed.

Because he felt that if he wanted a bicycle, he had to wait five or even ten years later, and his heart was broken.

But what he never expected was that Su Cheng actually gave him the bicycle!

This is really my brother-in-law!

Li Zhi was so excited that he cried. Whoever dared to say that Su Cheng was not good in the future would be anxious!

"Brother-in-law, you are so nice. You are really my brother-in-law! It's such a great blessing for my sister to marry you!" Li Zhi rushed up and hugged Su Cheng, full of tears.

"It's just a bicycle, don't cry, don't cry!" Su Cheng said, pushing Li Zhi's forehead hard.

I cry, but can you stop snotting your nose on me?

Now Su Cheng has no fear of this future Emperor of Tang Dynasty. No wonder Princess Changle always bullies him. Now Li Zhi has a bullying temperament.

Look, a bicycle moved Li Zhi so much.

Empress Changsun found it very funny. She thought it was a good thing that Chi Nu could have such a good relationship with Su Cheng.

Li Shimin felt a little embarrassed, his son was too unreliable.

Of course, he was also dissatisfied with Su Cheng giving the bicycle to Chi Nu. Su Cheng was really becoming less and less eye-catching.

Of course, it was just a little dissatisfied. After all, his ones belong to his son, and his ones belong to him. Is there any difference?

Although Li Zhi was not as tall as a bicycle, he raised his hands and was about to push the bicycle away.

However, the bicycle did not move.

Li Zhi looked up hard and realized that he had a pair of big hands on the bicycle at some point.

Li Zhi was confused. What's the situation? Whose big hand is this?

Oh, it turned out to be my father's big hand. Is his father going to help me push it? Just as Li Zhi was thinking this way, Li Shimin spoke with a smile.

"Zhi Nu, you are still young and can't ride a bicycle. Dad will keep it for you first. You can ride it when you grow up."

Although Li Zhi looked stupid with his nose, he was not stupid at all. He instantly guessed that his father obviously wanted to steal his bicycle.

Li Shimin's eyes were also very clear. Congratulations, you guessed it right, you just want to steal your bicycle. Can the ones I rob my son are called robbing?

Li Zhi was inexplicably sad and angry. He had a good brother-in-law and a father who cheated on his son. Life was really difficult.

Su Cheng couldn't help but be stunned. He still underestimated Li Shimin's shamelessness.

Empress Changsun couldn't help but look at Li Shimin in anger. Li Shimin smiled and didn't care at all. She pushed the bicycle and ran away, leaving you!

Li Shimin actually rode his bicycle away...

Su Cheng suddenly reacted a lot, what did I do when I entered the palace?

"Your Majesty, Your Majesty, wait a moment!" Su Cheng shouted quickly.

Li Shimin stopped the car and turned around and asked, "What else is there?"

Su Cheng was in a mess. You called me into the palace. What did you ask me about?

"Your Majesty, haven't you summoned me?" Su Cheng said angrily.

Li Shimin suddenly said, "Oh, nothing is wrong. Hou Junji's good news said that your bomb had made great contributions. I suddenly remembered whether there was any progress in your firearm surveillance. What was the cannon you mentioned?"

This time, Hou Junji led the army to the expedition and once again proved the power of gunpowder, so Li Shimin was also concerned about the situation of the Firearms Bureau again.
