Feng Xuhui was already used to hearing President Zheng and Su Yun talk about academic problems during mealtimes.

How many teeth were on the beer bottle cap … This kind of question was too remote and cold.

He chuckled and began to drink.

Old he was surprised.”Su Yun, you didn’t count, did you?”

Lin Ge stole a glance at the bottle caps on the ground. One, two … When he counted to 12, he felt that his eyes were a little blurry.

If he counted wrong, he would have to start from the beginning again.

“21.” “When we were still making beer by hand, it was 24 teeths,” Zheng Ren said. It was invented by William Peter at the end of the 19th century, because this type of teeth number is most suitable for sealing wine bottles. ”

Damn … Lin Ge rubbed his eyes and stared at Zheng Ren.

Boss Zheng was amazing. He even knew about such things?

Su Yun was about to say something, but she was stopped by Zheng Ren’s words.

Old he looked at Zheng Ren with his eyes wide open and asked,””Why did it change to 21? I didn’t expect there to be such a thing here. ”

“After the Second Industrial Revolution, the manual stamping method became a machine stamping. The 24 – tooth bottle cap could easily block the soft tube of the automatic loader. After changing it to an odd – numbered gear, this situation no longer occurred. ”

“However, because the 23 – toothed comb is not as tightly sealed as the 21 – toothed comb, people chose to use the 21 – toothed comb. The current beer cap was 21 teeth, and it was made according to the International Germany standard, DIN6099.

The requirements for the cap are seal – tight and bite. 21 teeth is the best compromise between these two requirements. ”

“Boss, you don’t drink, how do you know this?” Su Yun asked.

“I forgot where I saw it, but I can remember it after seeing it once. It’s just right for you to ask.” Zheng Ren picked up a skewer and took a bite.

Lin Ge smiled and pretended to be calm.

He didn’t say anything, but he was even more determined to cling to boss Zheng.

In history, there weren’t many people who could read steles on horseback and have a photographic memory, but there were also quite a few. Most of the people who could leave their names in history in peaceful times were this kind of people.

He didn’t expect boss Zheng to perform the surgery so well. So that’s what happened.

Old he’s eyes were still wide open like eggs. He looked at Zheng Ren and then at Su Yun. He shook his head with a bitter smile and started to drink.

Fan Tianshui’s face was blank, but his expression did not change at all, as if all of this had nothing to do with him. He ate skewers, drank wine, and looked on arrogantly.

“Boss, do you think uncle ning can set up his own standards when he starts to work on it? “Don’t just talk about Germany and United States now …” Su Yun suddenly felt that something was wrong.

The noisy crowd suddenly quieted down.

This feeling was very strange. Su Yun frowned and looked back.

A few black Rolls Royces had stopped by the side of the road. The attendants in black formal suits got out first and opened the door.

“I really found it.” Su Yun was a little emotional.”Boss, do you think they left a tracker on someone?”

“Location … No way. This place shouldn’t be hard to find. ” Zheng Ren smiled.

“Qin Tang, this side!” Su Yun raised her hand and called out to Qin Tang, who was getting off the car.

Qin Tang was obviously not used to the chaos here. He subconsciously covered his nose with his hand, but immediately felt that it was impolite and put his hand down.

Zou Yu walked over with a smile and said,””Do you all come here at night?”

“Occasionally. This is the second time.” Su Yun moved two chairs over, but she immediately noticed that Qin Tang and Zou Yu’s bodyguards were also with them.

Eating skewers at a roadside stall, with bodyguards …

What was the difference between this girl and the girl who was wearing a gold chain and a white Sable?

Well, there was still a difference.

The noisy crowd began to quieten down, and some people secretly took out their phones to take pictures.

Qin Tang frowned.

“Tell your people to disperse.” Su Yun replied,”the security in the capital is good. No one kidnapped you.”

It was indeed too eye – catching. Qin Tang waved his hand and a female assistant in a tight skirt walked over.

Qin Tang said something in a low voice and the female assistant turned around to leave. Soon, the convoy and bodyguards left, leaving only one person behind, who sat cautiously behind Qin Tang. She was like a little girl peeling garlic, guarding Qin Tang.

He was the man who had confronted fan Tianshui for a few seconds at the hospital.

The roadside stalls slowly returned to normal.

“Is this how you eat in Xiangjiang?” Su Yun asked.

“Hehe.” Qin Tang wanted to say that his family wouldn’t let him eat in such a small restaurant, but he swallowed the words.”This place is really full of smoke and fire.”

“Don’t talk nonsense, what nonsense is this about the mortal world. This kind of place was everywhere. What would you like to drink?” Su Yun asked.

“Beer will do.” Qin Tang said.

“It’s because something happened in the past and we lost money to avoid disaster. That’s why we have to have a sufficient security system when going out.” Zou Yu was more familiar with Zheng Ren and Su Yun, so she explained.

“The security in the capital is very good. Besides, isn’t old fan here? he’s much better than your bodyguards.” Su Yun said.

The man sitting behind Qin Tang squinted at fan Tianshui, his eyes sharp.

“Mr. Fan, are you also a retired soldier?” Qin Tang asked politely.

Fan Tianshui didn’t say anything, but nodded.

Qin Tang had seen fan Tianshui’s toughness in Xiangjiang city, and this man seemed to have a good relationship with boss Zheng.

He tried to keep smiling and forget about the noise and smell of the roadside stalls. “You’re good at fighting, may I know where you’re working now?”

“What do you mean by high or low? I’m just the hospital’s security guard.” Su Yun took over the conversation and bumped the beer bottle against Qin Tang ‘s.””I won’t go to Xiangjiang with you either. Let’s give up on it.”

“What?” Qin Tang was stunned.

In his opinion, being a bodyguard from home was much better than being in this place.

“Old fan, do you know military boxing?” Su Yun asked, ignoring Qin Tang’s shock.

“I practiced it when I joined the Army, but I’ve forgotten.” Fan Tianshui told the truth.

Qin Tang didn’t expect this.

“Let’s see, old fan only knows how to kill, not fancy moves. If I go to your place to be a security guard, I’ll see blood whenever something happens. What if I really throw him in?” Su Yun said.

Qin Tang smiled but did not say anything.

The bodyguard behind him was a little unhappy. He stared at fan Tianshui with an eager look on his face.

A killing technique? It was possible.

Even though Qin Tang was the heir of a large family and had little contact with fighting and killing, he could still faintly smell the bloody smell coming from fan Tianshui.

Qin Tang was also a young man who wanted to see fan Tianshui’s skills. But fan Tianshui never spoke. Every time he was mentioned, Su Yun would change the topic.

Lin Ge felt that these young people were very interesting. However, boss Zheng’s skill was also very high. He was able to make the young men of the aristocratic families in Xiangjiang sit obediently at roadside stalls and drink with them.

What was ability?

This was ability!

“Boss, one hundred more skewers!” Su Yun’s interest was piqued, and she shouted while holding the wine bottle.

“Okay, a hundred …” A tall and thin waiter who was shuttling through the crowd responded. Before he could finish his words, he stood still with a pale face.
