"Tang, please come with me to the national capital!" Archduke John sent an invitation to Tang Ping.

"This time there is a party, and I think everyone would be happy to have you, the Duke of the Tang Dynasty, attend."

"Me??" Tang Ping didn't expect the Grand Guild of John to issue such an invitation.

Tang Ping did not intend to use such an official identity to attend the gathering of European nobles at first.

It's okay to communicate mainly in private, but if it's a formal gathering, some red tape will make him feel too troublesome.

But after a moment's hesitation, he agreed: "Yes, Archduke John, but I have a request. ”

"Oh? You said!! Hearing Tang Ping's promise, Archduke John was very happy.

"I hope that Archduke John can hide my identity for the time being, so that I can more easily know what people think of our products."

Archduke John didn't expect Tang Ping to make such a request, to know that their European aristocracy was as high-profile as it could be.

It was almost inconceivable that something like Tang Ping would do, but Archduke John hesitated and agreed.

"Okay, Tang, since this is your wish, then I will respect you, and when the time comes, I will only tell His Majesty the King your true identity, and declare to the outside world that you are the Tang merchant we invited."

Tang Ping nodded and agreed, after all, this was a party organized by King Jindila, if even he had to hide it, it would be too much to say.

The two made an appointment to set off, and Archduke John was so comfortable to stay here that he planned to stay for another two days before leaving.

Anyway, it would be good to rush to the national capital before the party

When it was time to leave, Tang Ping came to the lobby of the Earl Resort, waiting for Archduke John to come out.

"Grand Duke Tang, I'm so glad to see you again!"

When Archduke John came out, he was still wearing the one that Tang Ping gave him that day.

"Archduke John, are you planning to go to the capital to kill the little girl there?" Tang Ping said jokingly: "You see that the little girl in our hotel doesn't dare to look up at you." ”

"Hahahaha!" John laughed openly, patted Tang Ping on the shoulder and said, "Don, you are really joking. ”

Then he looked at Tang Ping's side: "Are you going to the national capital like this?" Get your luggage to my carriage, and trust me, my carriage is the most comfortable. ”

As he spoke, he walked out of the hotel with Tang Ping, and the hotel has a special parking lot.

The carriage driven by the Grand Duke John's groom was parked here.

But as soon as he walked into the parking lot, he was attracted by a carriage next to him.

This carriage is different from their usual European carriage style, and the burgundy wooden carriage is full of delicate carvings.

Two large pieces of glass were pressed on the windows.

Needless to say, I know whose carriage it is.

Grand Duke John looked at Tang Ping, Tang Ping spread his hands, then nodded and said: "That's right, this is my carriage, I originally wanted to invite Grand Duke John to take my carriage to the national capital, but ......"

"But what?" Archduke John walked directly to Tang Ping's carriage and said, "What are you waiting for? Let's go! ”

He said to his butler, "You sit in my carriage and follow with your things." ”

Then he got into Tang Ping's carriage.

The first feeling was warmth, the carriage he usually sat in poured air into it as soon as he ran, and he had to wrap a thick quilt to keep warm.

As for Tang Ping's car, as soon as he went up, he felt that the temperature inside had increased a lot.

After Tang Ping followed and got into the car, he took off his coat directly. "Don, you're about to leave in a moment, won't you be cold?"

"No, isn't that warm?" Tang Ping said strangely, the temperature is almost twenty degrees, how can it be cold.

My carriage was specially made, and in order not to be too shocking in Europe, I still used a few horses to pull it.

But there was a diesel generator in the back of the car.

This car has heating plates on the roof and floor of the cabin, which is why it feels so warm.

At this time, the carriage had already begun to depart, and Archduke John found that Tang Ping's carriage was running without a trace of cold wind leaking in.

If it weren't for the fact that he could see the scenery outside rapidly receding through the glass window, he would have suspected that the carriage was still in place.

Because it's so smooth.

Even with the thick cushions, you can still feel the bumps in the carriage.

But Tang Ping's carriage, sitting on it, could only feel a slight tremor.

"This ...... Grand Duke Tang, why doesn't your carriage leak?? Nor shaking?? ”

Anyway, he had already been exposed in front of Tang Ping, and compared to Tang Ping, he didn't know a lot of things, so he simply didn't pretend.

"Carriage...... Shouldn't it be so that the wind doesn't leak and the ground doesn't shake? ”

Tang Ping's words almost made John's beard tremble.

Are you talking about human beings? Whose carriage runs so fast in winter without leaking wind?

And no matter how flat this road is, the carriage will tremble when it runs up, whose carriage is as stable as yours?

Seeing the appearance of Archduke John, Tang Ping stopped teasing him, and gave him a cup of hot tea as an apology, and then said: "This is actually very simple, and the carriage made by our Datang's mortise and tenon technology can be made without air leakage." ”

"Both?" Archduke John was a little incredulous: "Is it the same with ordinary noble carriages?" ”

"Really, a little bit of a civilian carriage can do it." As he spoke, Tang Ping took out a Luban lock from the drawer next to him and handed it to Archduke John.

"Our carpenters in Datang, they don't use nails, so they can be locked with the interaction between wood."

"This ......" Archduke John curiously fiddled with the Luban lock in his hand: "This really doesn't use nails?" ”

Together, these pieces of wood can be tightly locked?

"Well, if you can find a nail, I'll give you this carriage."

"Really?" Archduke John did not believe in evil, so he took the Luban lock and began to break it hard left and right.

He didn't believe that such tightly knit pieces of wood were not used for nails, how could it be?

After figuring out the way for a long time, Archduke John still said to Tang Ping in disbelief: "Borrow me a knife, I'm going to take it apart and take a look." ”

"What kind of knife do you want? Give me! ”

Tang Ping often plays, and after taking the Luban lock back, he put his fingers on it, and unlocked the Luban lock in a few clicks.

Then it was all in the hands of Archduke John: "Look, where is there a nail?" ”

Archduke John looked at the pieces of wood in his hand and was stunned: "This ...... This ......"

"This is mortise and tenon technology, our carpenters in Datang basically know it."
