"Tang, please come with me to the capital!" Archduke John extended an invitation to Tang Ping.
"There is a party this time, and I think everyone would like to have you, the Duke of the Tang Dynasty, attend it."
"Me??" Tang Ping did not expect that Archbishop John would send such an invitation.
Tang Ping had no intention of attending a gathering of European nobles in such a formal capacity at first.
It's fine mainly for private communication, but if it's a formal gathering, the red tape would be too troublesome for him.
But after a moment of hesitation, he agreed: "Okay, Archduke John, but I have a request."
"Oh? Say it!!" Archduke John was very happy when he heard Tang Ping agree.
"I hope Archduke John can temporarily conceal my identity so that I can more easily know what everyone thinks about our products."
Grand Duke John did not expect that Tang Ping would make such a request. He knew that the European nobles would be as high-profile as they wanted.
It was almost unthinkable for Tang Ping to do this, but Archduke John hesitated and agreed.
"Okay, Tang, since this is your wish, then I will respect you. 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 Datang businessman we invited."
Tang Ping nodded in agreement. After all, this was a party hosted by King Jindila. If even he had to hide it, it would be unreasonable.
The two made an appointment to set off. Archduke John felt so comfortable living here that he planned to stay for two more days before leaving.
Anyway, just get to the capital before the party.
On the day of departure, Tang Ping came to the lobby of the Earl Resort Hotel and waited 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 outfit Tang Ping had given him that day.
"Grand Duke John, are you planning to go to the capital to charm the girls there?" Tang Ping said jokingly, "Look at the girls in our hotel who don't even dare to look up at you."
"Hahahaha!" John laughed openly, patted Tang Ping on the shoulder and said, "Tang, you really know how to joke."
Then he looked next to Tang Ping: "Are you going to the capital like this? Take your luggage to my carriage. Believe me, my carriage is the most comfortable."
With that said, he took Tang Ping out of the hotel. The hotel had a dedicated parking lot.
The carriage driven by Archduke John's groom was parked here.
But as soon as he entered the parking lot, his attention was attracted by a carriage next to him.
This carriage is different from their usual European carriages. The burgundy wooden carriage is full of exquisite carvings.
There are actually two large pieces of glass placed in place of the car window.
Needless to say, he knew who this carriage belonged to.
Grand Duke John looked at Tang Ping. Tang Ping spread his hands, then nodded and said, "Yes, this is my carriage. I originally wanted to invite Grand Duke John to take my carriage to the capital, but..."
"But what?" Archduke John walked directly to Tang Ping's carriage and said, "What are you waiting for? Let's set off!"
He said to his butler: "You take my carriage and follow with your things."
Then he got on Tang Ping's carriage.
The first thing he felt was warmth. The carriage he usually rode in was filled with wind when he started running, so he had to wrap himself in a thick quilt to keep warm.
As for Tang Ping's car, as soon as he got in, he felt that the temperature inside had increased a lot.
After Tang Ping got into the car, he immediately took off his coat. "Tang, we're going to leave in a minute, won't you be cold?"
"No, isn't it very warm?" Tang Ping said strangely, the temperature is almost 20 degrees, how can it be cold.
My carriage was specially made. In order not to be too shocking in Europe, I still used a few horses to pull it.
But there is a diesel generator placed behind the carriage.
There are heating panels on the roof and floor of this car, so it feels so warm.
At this time, the carriage had already started to set off, and Archduke John discovered that Tang Ping's carriage was approaching without a trace of cold wind leaking in.
If he hadn't seen the scenery outside rapidly retreating through the glass window, he would have suspected that the carriage was still in place.
Because it's too stable.
Even with thick cushions, you can still feel the bumps of the carriage.
But Tang Ping's carriage could only feel a slight vibration when sitting on it.
"This... Grand Duke Tang, why is your carriage not leaking? It's not shaking either?"
Anyway, he had already been exposed in front of Tang Ping. Compared to Tang Ping, he didn't know many things, so he simply stopped pretending.
"The carriage...shouldn't be draft-proof and ground-proof?"
Tang Ping's words almost made Duke John so angry that his beard trembled.
Are you speaking in human language? Whose carriage can drive so fast in winter without leaking wind?
And no matter how smooth the road is, the carriage will shake when running on it. Whose carriage is as stable as yours?
Seeing Archduke John's appearance, Tang Ping stopped teasing him. He gave him a cup of hot tea as an apology, and then said: "It's actually very simple to prevent air leakage. Our Tang Dynasty's mortise and tenon joint technology can do this for carriages." It’s airtight.”
"Can it all be done?" Archduke John was a little unconvinced: "Is this true for ordinary noble carriages?"
"Really, a civilian carriage can be made even if it is slightly better." As he spoke, Tang Ping took out a Luban lock from the drawer next to him and handed it to Archduke John.
"Our Tang Dynasty carpenters don't use nails, they just use the interaction between the wood to lock it together."
"This..." Archduke John played with the Luban lock on his hand curiously: "This one really doesn't use nails?"
Can these pieces of wood be locked together tightly?
"Well, if you can find a nail, I'll give you this carriage."
"Really?" Archduke John didn't believe in evil, so he took the Luban lock and started to break it from left to right.
He didn't believe that the pieces of wood were so tightly joined together without nails. How could it be possible?
After working for a long time without finding out the way, Archduke John still said to Tang Ping in disbelief: "Lend me a knife, I want to take it apart and have a look."
"What kind of knife do you want? Give it to me!"
Tang Ping often played with it. After getting the Luban lock back, he pushed it with his fingers and unlocked the Luban lock in a few strokes.
Then he put it 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 the mortise and tenon technique, and our carpenters in the Tang Dynasty basically know it."
