"Don't I have a pager?"

"Ah? I forgot about the paging. Come on!"

Judging from Gu Hongzhong's rosy face, he had some good news.

His wife is pregnant again?

Impossible. If his wife gets pregnant again, he will be fined a lot of money.

That has to do with mobile phones.

Wan Feng's guess was correct. He followed Gu Hongzhong to his laboratory and indeed saw a mobile phone.

However, a mobile phone without a casing does not look like a mobile phone at all. It is just a circuit board with some electronic components soldered on both sides.

But the amazing thing is that this skeleton can actually make a phone call.

In other words, Gu Hongzhong has successfully researched mobile phones.

When Gu Hongzhong disassembled Wan Feng's mobile phone, Wan Feng saw the structure inside. The circuit board seemed to be much longer than the one Gu Hongzhong designed.

"Engineer Gu! Your circuit board seems to be much shorter than the one in my phone?"

"I integrated some of the chips inside and removed some transistors, so of course it's a lot smaller."

Then came the moment that gave Wan Feng a headache. Gu Hongzhong, who was so excited, actually explained to Wan Feng the structure and principle of the mobile phone.

What about radio frequency power amplifier, erasable and rewritable memory, dual-mode serial input frequency synthesizer, crystal oscillator...

Wan Feng understood everything he said, but that didn't stop him from feeling overwhelmed.

Just tell me that success is the end of it. What's the point of introducing this to him?

He doesn't plan to repair mobile phones in the future!
