Back in the 1990s, she became rich through scientific research

A trace of joy flashed across the sister-in-law's eyes, "Well, I believe you, I'll fix it for you."

Qin Hongfei's lips curled slightly, and she took the radio over to take a look. What brand it was, it was probably just an ordinary radio that cost more than a hundred yuan, but she didn't say it out loud. After taking a look, she determined the problem, "Your radio is indeed broken, and it can't play."

"Yes, yes, yes."

"This is our family heirloom, you have to fix it." The sister-in-law said with a distressed look, "Any price is fine."

"Repair fee, five hundred yuan." Qin Hongfei opened her mouth.

"What?" The sister-in-law widened her eyes and suspected that she had heard it wrong, "Five, five hundred, are you robbing?! My radio is only..." Realizing something, she hurriedly braked.

Qin Hongfei pretended not to notice anything and just looked at the radio seriously and said, "Sister-in-law, look at what you said. Five hundred yuan is a bit expensive, but you also said that your radio is a branded product and worth thousands of dollars. Five hundred yuan for repair, isn't that normal?"

"If you are willing, I will fix it for you."

"Really, I can fix it. Don't lie to me. If it breaks, you have to pay for it." Sister-in-law's eyes rolled.

"If it breaks, I will pay you ten times." Qin Hongfei said calmly, "We can write an agreement! Ask someone to testify, it has legal effect, and it is fair to everyone."

"Okay, then write an agreement..." Sister-in-law said anxiously, but she was not at ease. She ran to ask the neighbors on the left and right shops to testify. The owner of the repair shop next door was also pulled over to testify.

Qin Hongfei didn't care at all. She wrote the agreement at ease. After both parties confirmed that there was no problem, they signed it.

After the radio was repaired, sister-in-law gave five hundred yuan.

If it breaks, I will pay you ten times, five thousand.

Qin Hongfei said, "Sister-in-law, go get the money first. I will repair it for you after you get the money. If it breaks, I will give you five thousand immediately." The latter sentence attracted the sister-in-law greatly. She said ok and went home to get the money immediately.

This radio is impossible to repair, she knows it in her heart!

Because it is completely broken, and she broke it on purpose.

Qin Hongfei waited for the five hundred to come over, put it down, and took a stool for her to sit on, "Wait for half an hour, I will start to repair it for you."

The sister-in-law was in a good mood, thinking that she had received five thousand yuan, and said happily, "Don't worry, you can repair it slowly." Then she started chatting with others.

The owner of the electrician repair shop next door looked at Qin Hongfei mockingly. Others didn't know what was going on, but as the owner of the shop next door, he knew what was going on every day. This sister-in-law was from a nearby gangster family. She was famous for taking advantage of others, big or small. She was very mean. The radio was also completely broken. Today, Qin Hongfei must pay the money. That's good. The debt is too much. If she makes a fuss, she can get the shop earlier.

Wow, the technique is quite neat.

But thinking that Lao Qin himself is in this business, it is normal for the child to be influenced by him since childhood.

Qin Hongfei didn't care what they were thinking. He took a cross-head and a flat-head screwdriver and started to disassemble the radio. He knew what was going on after disassembling it. This was an old radio that was more than ten years old. The battery was broken, the tape contact was also problematic, and the voltage and current were all problematic... It was basically equivalent to a scrapped state.

If it were someone else, they might be at a loss, but Qin Hongfei happened to study science and technology research in her previous life for more than 20 years. Although she had never taken any courses, she studied things that were many times more difficult than this. Knowing the principles of this thing, she could naturally know what to do next. In her eyes, this small fault was as difficult as changing a light bulb. She took the electric welder in her hand and started to tinker with it.
