Datang: The prince of salted fish was overheard by Li Er

That night, in Xinglong Lake Food City, the private room dedicated to Li You was full of guests.

Chu Wang Li You held a small but very grand celebration dinner for Wei Zheng here.

The protagonist is naturally Wei Zheng.

How to change the personal invitation, maybe Wei Zheng would choose to refuse considering the impact, but Li You, he couldn't refuse.

With Wei Zheng as the protagonist, other accompanying guests are naturally indispensable.

The people who had the best relationship with Wei Zheng in Chang'an were all present, the most active ones were Cheng Yaojin and Li Ji, and Qin Qiong naturally attended together in order to keep an eye on these two younger brothers.

Besides these few people, Li You's target tonight, Zhang Liang, was also there.

Zhang Liang was born in poverty, and he also participated in the Wagang Uprising in his early years, and was subordinate to Xu Shiji's subordinates. Speaking of which, he has a good relationship with Wei Zheng and others.

In addition to Zhang Liang, Li You also invited several generals who were also in Wagangzhai, so that Zhang Liang's arrival did not appear abrupt.

A group of warriors is coming, so drinking is naturally indispensable.

Li You took out his own fine wine, which made Cheng Yaojin very excited again.

Since the last time he drank the wine, he couldn't forget it.

However, firstly, the wine is expensive, and secondly, the location of the Food City is too difficult to get.

They are all dignified people, and it is impossible for them to come and line up in advance like ordinary people.

In addition, they often have temporary military affairs, and the time is not fixed.

Once Cheng Yaojin asked his servants to come and line up, and finally got a seat, but he was called into the palace by Li Shimin.

When there are more people, the prepared wine will not be enough.

"King Chu, you are too stingy. It is rare for so many of us brothers to get together. How can these jars of wine be enough?"

Cheng Yaojin yelled while pouring wine into the bowl.

However, Wei Zheng on the side was not happy: "Although the king of Chu has said about today's situation, don't push yourself too hard."

"Such a good wine, of course you have to taste it slowly."

"It's a waste to drink as much as you do."

Faced with the big brother's accusation, Cheng Yaojin didn't dare to speak back, so he could only silently take another big sip.

Li You quickly helped to smooth things over: "Master Wei, Duke Lu is also a man of temperament, it's normal to drink two more drinks today if he is happy."

"It's because I didn't think carefully, so I sent someone to bring the wine right away."

Saying that, Li You stood up.

Cheng Yaojin laughed loudly and said, "The King of Chu is still interesting."

"Don't look at the young age of King Chu, the arrogance of this body has already surpassed many people."

"The king of Chu doesn't need you to go in person, I, Lao Cheng, will help you vent your anger."

However, Cheng Yaojin was about to stand up and walk out when Li You stopped him: "Duke Lu, don't bother."

"This private room on the top floor is the best private room in the food city. If you need to vent your anger on people with food and wine, what a drop in price!"

After speaking, Li You walked to a corner of the room, opened a mechanism, then took out a microphone and said, "Send another ten jars of wine upstairs!"

Then, under the surprised eyes of everyone, a second voice came from the agency: "Okay, boss, we will be there soon."

After Li You put down the trap, Cheng Yaojin impatiently walked up and asked, "King Chu, what kind of novelty is this?"

"Why does the sound come out from inside? Is this Taoism?"

Taoism flourished in the Li Tang Dynasty, and when the country was founded, there were two national teachers, Yuan Tiangang and Li Chunfeng, to help, so in his eyes, Taoism was real.

Li You shook his head and said, "This is called a megaphone, and I can use this thing to contact the little girl below."

The principle of this microphone is actually very simple.

It is a paper cup phone that is clearer and has a longer transmission distance.

In fact, this principle has also been developed and utilized in this era.

But Li You's one was made after combining the Mohism mechanism and the ingenuity of the great inventor Haig.

Not only the call is clear, but also has the effect of amplifying the sound.

After Li You explained something, Cheng Yaojin immediately shouted that it was fun, he walked over and picked up the megaphone and said: "Hurry up to deliver the wine, I can't wait!"

Soon there was a voice from the other side: "Good guest officer, the wine has been delivered, please wait patiently."

Sure enough, after these words were finished, the door of the private room was gently pushed open, and the two mistresses appeared in front of everyone with wine.

"It's fun, this thing is fun."

Cheng Yaojin went over to pick up a jug of wine, and came back to play with it.

Taking advantage of this moment, Li You explained: "This megaphone has already been installed in each private room in the food city."

"When you come to eat in the future, if it is not convenient to go out to add food, you can use this to order food."

Hearing this, everyone got up and came to the microphone.

Seeing that everyone was coming, Li You began to explain.

Wei Zheng on the side picked up the microphone and sighed, "The King of Chu's design is really ingenious."

"The sound can be transmitted in both directions when you pick it up, and it will be completely isolated after you put it down."

"It's really convenient to use this thing to order food."

In fact, these princes have more or less encountered similar problems when they came to eat.

That is, the food and wine that I often order is not enough, so I need to come out and let the waiter come over to add food.

But the identities of the people they came to have dinner and banquets were all distinguished, and it was a bit inconvenient to show their faces in public.

So the problem of adding vegetables has been bothering them.

But now, this problem has been solved by this megaphone.

Li You chuckled, then put the sound transmitting tube away, and said: "This sound transmitting tube must be put away after use, if not, the sound in the room will continue to spread."

"If it's just the kitchen that's alright, don't be afraid. If people in other rooms pick up the microphone, the movement in this room will be heard by people in other rooms."

Hearing this, Li Ji on the side became interested.

Among these people, he had the most ghost ideas. Although Li You didn't say anything at the moment, he had already thought of some applications in espionage.

Immediately, Li Ji picked up the megaphone again, signaling to everyone not to speak, he wanted to see if there were any daredevils in other rooms who didn't put the megaphone down after using it.

Sure enough, the crowd didn't wait long before a man's voice came from the microphone.

"Xiong Er doesn't know what kind of shit luck it is, but he even won a lottery when he came out to eat!"

"It's very difficult to book a private room in this food city."

Then a charming woman said: "It's a pity, he is not blessed to enjoy such fine wine and food."

"He just ordered the food, and he has something to go, and Zhang Lang and I should enjoy the good things!"

After that, the man and woman started a series of intimate conversations, and all the princes present tried to hold back their smiles.

However, among the people present, not all were holding back their laughter, and there was one who was holding back his anger.

This person is Zhang Liang.
