"Don't rush to the electronics market yet, take a long-term view."

If she just bought some electronic components and accessories and made a simple video doorbell, she could have done it.

But after Xu Yanni's discussion, the topic had deviated a bit and moved to the surveillance video, and since so much had been said, it was no longer possible for the two of them to do it quietly.

"Yeah." Xu Yanni nodded repeatedly, "How about going to your house?"

I would also like to visit the site and take a look at Wang Zhaozhao's initial research draft.

Wang Zhaozhao's eyes lit up. "Okay, welcome, welcome."

However, I have to ask Chen Pei's willingness, "Hey, Pei Pei, come to my house and play?"

"Sure, but don't think I don't know that you want to go back and continue studying how to make a doorbell." Chen Pei said with a hum.

Wang Zhaozhao laughed dryly, but Xu Yanni was talking nonsense seriously, "Who is the doorbell? Why should we study how to deal with it?"

Well……

Wang Zhaozhao and Chen Pei felt a chill and took a step back in tacit understanding. Eh!

Xu Yanni noticed that this was a subway station, otherwise she would have opened her arms and pounced on them.

However, Wang Zhaozhao thought about it and felt that he couldn't just think about studying the doorbell, which would be too unkind to Chen Pei.

"Let's have a barbecue tonight? My house isn't that fancy, but it's still spacious enough...it's just a little warm in this hot summer."

Xu Yanni and Chen Pei's eyes lit up. Let's have a barbecue!

"Should we ask her brother's good friend Song Kai to come over? That guy is the best at eating, drinking and having fun." Xu Yanni suggested.

There is no conflict between barbecue and research, hahaha.

"Okay, give him a call." Wang Zhaozhao had no objection. Song Kai was good at handling things, and it would be fun with him around.

She thought for a moment, "And that... Zhao Jianguo, isn't he also your brother's childhood friend? Let's see if he's free."

"Let's ask him. If he's not at work, he might be with Song Kai." Xu Yanni said as she took out her cell phone.

Wang Zhaozhao introduced Zhao Jianguo to Chen Pei, briefly mentioning his identity, mainly saying, "...his appearance doesn't quite match the name 'Jianguo'."

He's tall, wears round black-framed glasses, has a clean complexion, and is a refined and clean person..."

"Eh? No signal?"

Xu Yanni suddenly shouted like thunder, interrupting Wang Zhaozhao's words.

She quickly took out her cell phone.

Chen Pei didn't understand, so he just stretched his neck and looked left and right at the small cubes in Wang Zhaozhao and Xu Yanni's hands.

Wang Zhaozhao subconsciously looked for the reason in the system.

System: "This system cannot answer you."

"...I'm not asking you to answer," Wang Zhaozhao said slowly. "My analysis is that it's not a problem with the base station signal, but rather that our technology needs to be upgraded. The signal from the ground base station can't penetrate into the subway tunnel."

"You know why you're asking me?"

"It was so sudden, I was just startled."

Wang Zhaozhao felt relieved and left decisively.

She said to Xu Yanni, "Wait until you stand up and then fight..."

Xu Yanni obviously also thought about the problem of signal penetration from ground base stations in underground tunnels.

"Everyone forgot to consider this." She said with her hands spread out.

"Maybe we have considered it, but this is all we can do at the moment. However, since we are trying it out, we have the responsibility to discover any problems, and they must be reflected in the report when the time comes." Wang Zhaozhao said calmly.

"You're right!"

Xu Yanni stopped hesitating, put away her phone, and pulled Wang Zhaozhao and Chen Pei aside to discuss what they should buy after getting off the subway and going directly to the vegetable market.

Zhao Mai and Dapin looked at each other. They considered themselves to be calm and steady, but now they realized that they had a lot of room for improvement in their mentality.

We must make progress! Urgent!

They arrived at the station. As soon as they got out of the subway station, Wang Zhaozhao and Xu Yanni took out their cell phones in sync to check if there was any signal.

"Fortunately, the base signal is fine." Xu Yanni breathed a sigh of relief.

Wang Zhaozhao pursed her lips and smiled, "Can you find Song Kai by phone?"

"Just call them one by one."

"Can."

Wang Zhaozhao gave her a thumbs up and dialed Xu Jiaying's cell phone number.

"Well, there's no signal outside of Jing City."

She shrugged and put away her phone. She had called knowingly.

Xu Yanni didn’t find the person she called the first time, so she called a second time and found Song Kai.

Song Kai on the other side should have known that she was calling from a cell phone, but he kept talking on and on and on and refused to hang up, leaving Xu Yanni speechless.

"My phone needs credit too, bye!"

After saying that, just hang up.

Song Kai on the other end of the phone listened to the beeping sound, laughed, and kicked Xu Zifu in the air, "Brother, our little girl is much more awesome than you, her brother."

"My sister is amazing. Am I proud of myself?" Xu Zifu, who was dressed in casual clothes, said calmly.

He went on a mission and returned home a few days ago. After a busy period of work, he finally finished his work and went home in the afternoon to start a three-day vacation.

When I got home, I found out that his sister, who was even busier than him after going to college, returned home the day before yesterday. Well, it was a "grand" return home.

Just a little before he got home, his sister went shopping with her little sisters.

Song Kai knew he was back and called him immediately.

If it wasn't for the fact that Zhao Jianguo was rarely free, he wouldn't have bothered to go out in the hot sun to play with Song Kai.

"Jianzi, you haven't seen the girl for a long time, right?" Song Kai looked at Xu Zifu with contempt, then turned to ask Zhao Jianguo.
