Chapter 490 Know-it-all

Everyone talked and laughed, and the initial nervousness and restraint disappeared.

Netizens in the live broadcast room were extremely envious.

[Ah ah ah, I also want to be invited by the big sister! I don’t know, what are the criteria for judging? 】

[The eldest sister’s Weibo is there. If you read it, you will know that each of them works very hard in life. 】

[For example, He Jinyu was originally unwilling to study at all, but then he suddenly became enlightened just to meet his eldest sister, and his grades were like a rocket. 】

[The housewife was a little depressed after giving birth to her child. Later, she was influenced by her eldest sister and began to write. She is also a slightly famous writer. 】

【...The charisma of idols is really strong...】

[My mother has always opposed my pursuit of stars. Cheng Ling was the first celebrity that my mother supported me in pursuing. 】

[I am willing to spend money on the eldest sister, and I hope that the eldest sister’s company will provide me with more opportunities to spend money on her - supporting her means supporting the ideal world in my heart. 】

[I think of a male star in Neon Country who also selects fans to interact with. The way of interaction is that these selected fans can lie on the ground and let him walk over. 】

[A male singer in the United States is said to be particularly doting on his fans. The way he dotes on his fans is by spitting at the women in the audience. 】

[There is also a female celebrity in our country. The way she favors her fans is that fans can spend money to buy the clothes she wears. Laughing to death. The price of the clothes is several times higher than brand new ones. 】

[On this point, I am a fan of Cheng Ling to the end. 】

【hypocritical! Cheng Ling has no lower limit! This is how you catch people’s attention! Just showing off. 】

[Haha, if you have the ability, the real owner of your family can also act cool! The real owner of your family doesn't even bother to pretend. 】

After a while, the staff of Muxin Villa came to remind us that the lunch restaurant on the next mountain peak was open.

The restaurant is built on the top of a very steep mountain and requires a cable car to reach it.

So, everyone took the cable car to the restaurant.

After getting on the cable car, He Jinyu leaned on the glass and looked down curiously.

Sister Xia was afraid of heights and sat motionless in her seat with a pale face.

He Jinyu pointed to the black dots on the upper edge of the glass and asked, "I've always been curious. There are these black dots on many glass windows - what are they used for?"

Cheng Ling replied:

"Prevent the glass from bursting due to uneven heating. Because the edges are not easy to absorb heat, we use the principle of black heat collection and rapid heat dissipation to balance the heat of the glass, thus achieving the function of protecting the glass."

"There are also small black dots on the edge of the front windshield and above the rearview mirror. These black dots are to reduce the damage caused by strong sunlight to the driver's eyes."

【? Even the eldest sister knows this kind of unpopular knowledge! 】

[I would like to ask, looking at the entire entertainment industry, who else has a broader knowledge than the eldest sister? 】

[Stop bragging. If you have the ability, compare it with university professors. 】

[My sister Ling is an actress, not a university professor. Why should I compare with university professors? 】

[Cheng Ling is deliberately showing off! 】

[Why, do you think you are pretending to be stupid even though you know this knowledge point? If you really pretend to be stupid, you will say at that time: Cheng Ling's know-it-all character has collapsed. 】

Brother Xiong, a relatively taciturn programmer, pushed up his glasses and spoke in a heavy voice: "This kind of tempered glass is very strong. Before, there was a heavy rain in the city where I worked, and the roads were flooded. A buddy was trapped in the In the car, he couldn't open the window, and there was no hammer in the car... When the rescue team found him, they said that his knees were broken trying to break the window, but the glass was not broken..."

"I've heard about this too."

"Since that heavy rain, many people have hammers ready in their cars."

"When the glass can't be broken, that person must be feeling desperate."

Cheng Ling said: "Let me tell you a way to break the glass quickly - use the rubber band around you, separate your index finger and thumb, put the rubber band on, then tie the ring or key to the outer rubber band, and pull the rubber band in the opposite direction , reach the limit, and then let go of the glass to break it easily."

"In addition, try to hit the edge of the glass. Because of the force in the middle, the entire glass surface will be stressed together and absorb energy. However, the frame has a fixed function and the deformation is small, which can maximize the effect of knocking."

"Sister Ling, you really know a lot of knowledge!"

"I am the one who fell in love with the eldest sister in "Desperate Survival". She is really amazing! She is extremely reliable!"

"Sister, if you have any other interesting knowledge, please tell us!"

There is still some distance to go before the peak.

Being idle is also idle.

So, Cheng Ling thought for a moment and said, "Yes, let me just mention a few that are practical and relatively easy to implement."

Several people immediately listened attentively.
