The girl took Su Xuan into the backyard, and Su Xuan found that there was a hole in this mansion.

It doesn't look like the backyard of a mansion at all, it looks like a mess, but rather like a small workshop.

This courtyard is extraordinarily large, and it is almost comparable to a small school field in the military camp of the Wushuang Army.

The courtyard was filled with all sorts of weapons and utensils, some of which were good and others that were fragmented.

"Woman, what are you?" Su Xuan was a little confused, but he seemed to have thought of something.

"Here, take a look at this."

The girl pulled Su Xuan to squat down, and there was a small wooden horse on the ground. It's not a single piece, it's a patchwork that looks like a building block.

After the girl reached out and tinkered, the little wooden horse actually moved on its own, but it didn't go far before it stopped.

Good fellows, Wooden Ox Flowing Horse?

Could this girl be an inventor?

"You invented this?" Su Xuan asked.

"This is what I learned to do from an ancient book I got by chance, and I can only make it so small that if it were the size of a real horse, it might fall apart after two or three steps." The girl said, and raised her hand to point to a pile of rags not far away.

"It's amazing that you can do this." Su Xuan said seriously.

"I'm not trying to hear you praise me, I'm trying to ask you for advice. It is recorded in ancient books that this Trojan horse weighs 50 catties and can carry 500 catties. Look again!"

The girl took the wooden horse back, picked up a boulder directly, and put it on it.

"Pants~"

The Trojan was crushed and scattered.

"My Trojan horse weighs ten pounds, so it stands to reason that it can carry a hundred pounds

？ But this stone weighs only 80 pounds, why did it crush the Trojan horse?" The girl asked.

Su Xuan seems to have discovered a new world.

This is to discuss academic issues with him, it seems that this girl is not a fish that has slipped through the net in nine years of compulsory education, her little head melon, in addition to eating apples and watching Ma Yi, there is still something.

"You said that the ant could lift an object countless times heavier than itself, so why can't this Trojan horse? You say that ants have a lot of tendons, how to put tendons on a Trojan horse? It's got no flesh." The girl continued.

"Do you still have a Trojan horse? Show it to me."

"Yes, wait for me."

Soon, the girl took a new Trojan horse to Su Xuan, and after Su Xuan played with it a few times, he disassembled the Trojan horse and studied it for a while.

It turns out that the structure inside this Trojan horse is quite complicated. The power it can move forward comes from the rubber bands inside.

"Did you make all this mortise and tenon?" Su Xuan asked.

"Yes."

Su Xuan couldn't help but be amazed, linking the mortise and tenon technique of the Trojan horse, that is called a master.

I didn't expect this girl to have such skills at such a young age.

"Are there any drawings?" Su Xuan asked again.

"Oh yes, I forgot to show it to you, wait for me."

Soon, the girl took the drawings to Su Xuan again.

Su Xuan stood up and took the drawings and the Trojan horse to a table.

"This Trojan horse has no flesh, but it has a keel. The reason why it can't bear heavy loads is because the keel is too fragile." Su Xuan said in a deep voice.

The keel is the internal main structure of the Trojan horse.

When the girl heard Su Xuan's words, she seemed to understand something.

"The internal structure can be streamlined, the keel is replaced with steel, and the mortise and tenon joint is only responsible for bridging, not bearing

Heavy. By solving these two problems, the Trojan horse will be able to lift objects ten times heavier than itself." Su Xuan said.

"Steel! I didn't think of that! That's right! Ants have a lot of tendons, so they have a lot of strength. If the keel of this Trojan horse is replaced with steel, won't it be equivalent to a new pair of bones?" The girl's eyes widened, as if she had discovered a new world.

Then the girl frowned again.

"But the weight of the Trojan itself has increased

, then it won't be able to go a few steps. This rubber band doesn't have much strength, and it can't pull a Trojan horse that is too heavy." The girl said.

"Do you know what clockwork is?" Su Xuan said with a smile.

"I don't know."

"I'll give you a better drawing and see if you can make it." If it happens, I can guarantee that this Trojan will keep going."

"Really?"

"Try it."

"You're so smart! It seems that I didn't find the wrong person, you hurry up and improve the drawings, hurry up, I can't wait!"

Su Xuan took the drawings and began to improve them.

If this wooden ox and flowing horse can really be done, this is definitely a great thing.

Not long after, Su Xuan finished drawing the drawings, and the girl immediately picked them up, and no one else studied them.

Su Xuan stood for a long time, and he didn't see this girl continuing to deal with Su Xuan.

So Su Xuan asked, "Do you have any questions?"

The girl still didn't answer.

"Then I'll go first, and if you have any questions, feel free to come to the household department to find me."

The girl nodded.

"Haven't you asked for the woman's name?"

The girl still nodded.

Su Xuan snatched the drawings, and the girl immediately became a little angry.

"Do you want to make something more fun?" Su Xuan asked with a mysterious smile.

"What?"

"Weapons

。」

"You still know weapons?"

"I'll draw you drawings and see if you can make them."

"As long as there are drawings, there is nothing I can't make, just give me the drawings."

Su Xuan stayed in this courtyard all morning and drew drawings all morning.

He was now worried that he could not find a good craftsman, and judging from the mortise and tenon joints made by this girl, she must be a qualified craftsman.

Talents are often around you.

"Okay, I'll give you some drawings this time, and when you make this, I'll give you new ones."

"Hmm."

The girl began to study the drawings again, and no longer bothered with Su Xuan.

Su Xuan felt bored, so he quietly left the courtyard.

After walking out of the gate, Su Xuan did not forget to glance back at the gate of the mansion.

Zhao Mansion.

As he walked, he thought about it, Zhao Ke is a big surname, facing inside and out, there are a lot of big guys with the surname Zhao.

Whose offspring is this girl?

Judging from her relationship with the fourth princess, the status of this adult must not be low.

At first, Su Xuan thought that this was the county lord of a prince's family.

But the owner of this mansion is surnamed Zhao, so it can't be the county lord.

In the Jingyang Dynasty, there was no canonization of a king with a different surname.

No matter what her identity is, in short, Su Xuan wants to take her into her pocket.

Now Su Xuan's subordinates can be said to be all stunned, and there is not a single technical talent.

This little genius who loves apples must not be missed.

However, Su Xuan still had to inquire first about what the identity of this girl was.
