After a while, Zhao Xuan finished fiddling with it, installed the projector's shell, inserted it into the socket, and turned on the projector. There were images in the TV and the video was played normally.

"Ah Hyun, Brother Hyun, you are this." Park Jae-seok gave a thumbs up.

The other teenagers also changed their name to Zhao Xuan, and they unanimously changed "A Xuan" to "Brother Xuan".

Zhao Xuan was proud: "It's just a little bit."

Liu Sixi said: "Brother Xuan, you have this skill and can open a repair shop to make money."

Zhao Xuan: "I open a repair shop to make money, what about you? You don't know how to repair it, so how can you make money?"

The five teenagers were moved when they heard this. It turned out that Brother Xuan gave up such a way to make money for them. Brother Xuan is really loyal. Brother Xuan is their lifelong boss!

Zhao Xuan pulled the corners of his mouth.

Oh, these teenagers are so simple.

Why doesn’t he make money by opening a repair shop? Because he can’t make much money.

If Zhao Xuan wants to improve the family's economic situation before his biological parents find him, he must have a certain economic foundation to gain a say in this identity exchange.

Moreover, he also wanted Grandma Zhao to enjoy a happy life early, eat well and dress well, and not to be too old to be lying outside.

Private detectives don’t invest much. As long as they get out of fame, they will make more money faster and more when they have more business in the future.

However, being a private investigator still requires some tools.

For example, cameras, voice recorders, monitoring equipment...

These investments are quite large.

Zhao Xuan looked at the projector he had repaired and suddenly stood up.

"Brother Xuan?" An Chengcai looked at Zhao Xuan in surprise.

Zhao Xuan said to the five people: "I want to go to the scrap purchase station, do you want to go?"

The teenagers were puzzled: "What are you doing when you go to the scrap purchase station?"

Zhao Xuan's mouth curled slightly: "If you want to do a good job, you must first sharpen your tools."

Five teenagers were full of question marks.

Cui Guangen: "Brother Xuan, what language did you just speak?"

Zhao Xuan: "Chinese."

Jin Shaoyuan applauded: "Brother Xuan is so awesome and can speak foreign languages."

Zhao Xuan had already walked to the door: "You want to learn, I can teach you."

"Forget it." The five teenagers laughed. They were poor students and their most annoying was learning. They didn't even learn the language of the Republic of Korea well, so how could they learn the languages ​​of other countries?

Zhao Xuan stared at them with deep eyes.

If you want to be a good private investigator, you must know the skills.

Wait, he has time to let the five poor students gradually grow into top students.

Six people rushed to the scrap purchase station in a mighty manner. When they arrived, Zhao Xuan directed five young men to find out the worn electrical appliances and electronic devices.

These worn-out electrical appliances are completely useless and can still be used, so they have been bought home long ago.

Therefore, this pile of rag was not valuable. Zhao Xuan spent only 10,000 yuan to buy all these things back home.

"Brother Xuan, what are you doing for buying these things?" An Chengcai fiddled with a tattered walkman and asked Zhao Xuan curiously.

Zhao Xuan took the Walkman from his hand and replied: "Assemble some tools that will help our detective work."

While speaking, the Walkman had been dismantled into a bunch of parts.

He found useful parts from it, and assembled them with other parts, and assembled them into a lighter-shaped recording equipment.

Zhao Xuan showed the function of the equipment to the five teenagers and said, "In the future, if you find out the news, bring this thing with you and record the information you think is important."

The five teenagers nodded repeatedly, their eyes full of amazement and admiration.

After that, Zhao Xuan assembled two cameras, three recording equipment, and even assembled a wiretaper and a pinhole camera.

Five teenagers: “…”

Five teenagers offered their knees to Zhao Xuan.

Promotional advertisements did not work, and no business came to the door.

Zhao Xuan used these free time to teach the teenagers how to use these devices, and taught them some tracking skills, some questioning skills, even some psychological knowledge, and some camouflage skills.

The teenagers are not stupid, and the reason why they are poor students is because they are not interested in the knowledge in the school and have no intention of learning. But what Zhao Xuan taught them is the skills to make money, and it is very interesting. The teenagers learned it seriously and mastered these skills soon.

Zhao Xuan secretly guided them to learn more knowledge.

Zhao Xuan rented back a lot of Hollywood blockbusters, all with original sounds, only the subtitles were in Korean. The boys listened to English and watched subtitles, and the fun of watching dramas was less. But because these Hollywood blockbusters were really exciting, they were all types of action movies, and special effects movies that middle school teenagers liked to watch... In order to watch movies, the boys had to listen to the original sounds to watch movies.

In this way, the teenagers' English level gradually improved.

At least, when they face foreigners, they can have simple daily conversations with others.

A month passed in a blink of an eye, and the teenagers learned their skills, but their initial enthusiasm faded a lot.

It has been so long that their detective agency has not even received a business.

When Zhao Xuan saw everyone lying lazily on the tatami, he returned to their decadent appearance when he first came to this world. He narrowed his eyes, walked forward, and kicked everyone.

"All up, it's time for us to do things."

"Doing things?" The five teenagers immediately jumped up when they heard this, "Brother Xuan, is there any business coming?"

Zhao Xuan: "Business is not available, but we can find a business ourselves."

The five teenagers' shoulders drooped: "Go to find it yourself? How do you find it?"

Zhao Xuan: "Follow me, I will find it naturally."

The five teenagers were still very confident in Zhao Xuan, and he heard this and followed Zhao Xuan out obediently.

Zhao Xuan had a goal. He took the teenagers out of the slums and walked to a nearby community where the rich people lived.

The teenagers walked to the entrance of the community and saw the security guard guard at the gate, and couldn't help but shivering, but seeing Zhao Xuan walking in with his head raised and his chest without squinting, the five teenagers seemed to have confidence in their hearts, puffed up their chests, and followed Zhao Xuan.

As expected, they were stopped by the security guards in the community.

Facing the security guard's inquiry, Zhao Xuan answered with confidence and was very confident: "It was Mr. Yin who asked us to come. We are private detectives, and Mr. Yin entrusted us to help."

The security guard seemed to have some understanding of Mr. Yin’s house. After hearing Zhao Xuan’s words, he showed a look of silence and did not stop them. He let a few people enter the community.

Five teenagers: "??"

Come in so easily?

An Chengcai ran to Zhao Xuan and asked, "Brother Xuan, you lied to us. The business really came to us. We thought we really wanted to find a business by ourselves."
