Yoo-hyun was still worried.

“Sigh.”

Hyun Jin-geon asked him as he let out a sigh.

“Is it because of Da-hye?”

“Yeah. She knows everything, but why is she being like that? She’ll never let me go.”

“I knew she would, so I prepared something.”

“What is it?”

Yoo-hyun widened his eyes as Hyun Jin-geon winked at Nadoha.

Nadoha nodded and connected the Huawei communication device on the table to the new server that Hyun Jin-geon brought.

The server chip used FPGA (Field-Programmable Gate Array) instead of ASIC (Application-Specific Integrated Circuit) due to the semiconductor production problem.

It was not optimized, but its performance was much better than the previous one.

Click.

As Nadoha clicked the mouse button, a simulation screen popped up on the conference room screen.

It showed the server and the mobile phone terminal connected to the network device in the shape of a utility pole.

Hyun Jin-geon said.

“I bet Huawei will use a similar environment when they inspect the communication device. They’ll directly connect the server and the terminal, but they’ll also show a nice simulation screen.”

“So you made this?”

“Nice things are good to eat, too.”

“That sounds good, but…”

How can he persuade Da-hye with this?

He put aside his doubt for a moment as Nadoha tapped the phone.

Then, the server and the phone started to communicate through the Huawei communication device.

It looked like a normal communication device test, but it was not.

The program built into the server accessed the backdoor in the Huawei communication device, and the internal key installed on the phone opened the door.

The communication device was manipulated and the network information of the CCTV, hydroelectric power plant, and other devices connected to the simulation flowed out.

It took less than five minutes to crack it.

Clap!

The two geniuses high-fived and Yoo-hyun stared blankly.

Tap tap.

Hyun Jin-geon tapped Yoo-hyun’s shoulder and smiled.

“Kid, you’re surprised, huh?”

“…”

“Huawei might not even know that the information leaked. We made sure not to leave any evidence. Don’t you think Da-hye will be relieved by this?”

As if.

Yoo-hyun had a lot to say, but he swallowed it.

He thought he had to persuade Da-hye personally.

He pushed his worries aside and focused on reality.

“Hmm, I think we should minimize the number of people going on the trip.”

“Of course. The three of us should be enough, right?”

“No. One more. We need an interpreter.”

“Why? Don’t you all speak English as a basic skill?”

“That’s what you experienced with the Chinese in Silicon Valley. The mainland engineers are different. If we need to bridge the gap somehow, it’s better to have our own interpreter than theirs.”

That was what Yoo-hyun learned from working with many Chinese companies.

It was better to use an interpreter than to communicate poorly, and the interpreter had to be from our side.

That way, we could deal with problems more closely.

Hyun Jin-geon nodded.

“True. We have to stop by somewhere before going to Huawei.”

“Stop by where?”

“We have to test if we can access the Huawei communication device from the Chinese internal network in advance. Of course, it will work, but just in case.”

“We have to do that, of course. But who are we taking?”

It was hard to find someone with Chinese language skills among the employees, since River had not entered China yet.

He couldn’t trust Vice President Woo Jungcheol either.

Should I look through the sales staff of Hansung Electronics?

Yoo-hyun was making a list in his head when Nadoha cautiously joined in.

“Hyung, I actually know someone who’s perfect for this.”

“Who?”

“He’s fluent in Chinese and an expert in communication. He’s a bit young, though…”

“What does age matter? Who is he?”

Yoo-hyun said casually and Nadoha brightened up.

“Right? I knew it. You would agree. His name is Shin Sunhoo, a smart guy who joined A1 earlier this year.”

“Shin Sunhoo? Oh, the one who graduated from a university in China?”

“Yes. Let’s take him. He’ll be really helpful. He’s also very eager.”

“Really? When did he say that?”

“Uh… I asked him casually when I was preparing to infiltrate Huawei.”

This guy, he was serious.

Yoo-hyun looked at him incredulously and Nadoha grinned.

He almost caused a big trouble if I had left him alone.

“What a guy.”

With Yoo-hyun’s dumbfounded expression, the four members who would go to China were confirmed.

The progress was swift as the interests aligned.

Huawei agreed to Yoo-hyun’s visit and Vice President Woo Jungcheol decided to guide him personally.

Da-hye had no choice but to approve it as the matter went this far.

But she held out her pinky finger.

“Yoo-hyun, promise me you’ll come back without any problems.”

“There’s nothing to worry about. I’m fully prepared.”

“Still. Safety is the top priority.”

Squeeze.

Yoo-hyun nodded as he hooked his pinky finger with hers.

“Don’t worry. I’ll finish it well and come back.”

“Take care of your health, too.”

“Sure. I’ll call you every day.”

“No, don’t bother yourself too much.”

“I just want to hear your voice.”

The two exchanged affectionate gazes at the airport.

Hyun Jin-geon watched them from afar and snickered.

“Who would have thought he doesn’t have a girlfriend?”

“Tell me about it.”

“Huh? Nadoha, you have a girlfriend?”

Hyun Jin-geon asked in surprise and Nadoha shrugged his shoulders.

“Of course. I have someone who’s waiting for me to come back soon.”

“Really? So you decided to return right away without staying longer in China?”

“That’s all I can tell you. The rest is a secret. Sun-hoo!”

Nado-ha, who was jokingly smiling, raised his hand and a man with a round face and deep dimples ran over.

“Yes, sir.”

“Are you all set?”

“I packed everything and bought a SIM card. I’m ready to go.”

“Smart kid. Let’s go ahead of the others.”

Nado-ha, who had his arm around the man’s shoulder, walked out briskly.

Nado-ha usually used honorifics even to the lowest-ranking employees.

The only man he treated casually was Sun-hoo, who was in charge of interpreting for this China trip.

Sun-hoo was an employee of Aiwon and a Chinese exchange student. He stuck close to Nado-ha’s side.

Nado-ha took good care of his subordinate.

The two of them looked like close brothers.

Hyun-jin-geon, who was sitting on a bench at the airport gate, muttered as he watched Nado-ha and Sun-hoo chatting away.

“They look really close.”

“I know, right? Nado-ha was always like the youngest, but he seems happy to have a younger brother.”

“You think he likes him just because he’s young? He picked him himself, didn’t he?”

“That’s true.”

Sun-hoo was an employee that Nado-ha personally selected and taught everything from scratch.

He managed to follow the genius’s instructions that most people couldn’t keep up with.

‘That’s why Nado-ha likes him.’

He had a friendly personality and a quick action. And he was also skilled.

Thanks to Sun-hoo, this trip felt easier.

Yoo-hyun, who chuckled, got up from his seat.

The announcement for boarding the plane to Shenzhen, China was ringing through the speakers.

Shoo-woo-woong.

As they landed at Shenzhen airport in China, Yoo-hyun was greeted by the hot tropical climate.

Beyond the palm trees that surrounded the airport, buildings that seemed to pierce the sky were visible.

Sun-hoo, who was somewhat awkward with Yoo-hyun and Hyun-jin-geon in Korea, took the lead.

“Shenzhen is one of the four major cities in China and the first special economic zone in China. The city was completely redeveloped and received a lot of praise from foreigners for being unlike China.”

“Have you lived here before?”

“Yes, sir. I attended Shenzhen University for a semester as part of an exchange program. Back then…”

Sun-hoo, who opened his mouth, guided them around like a tour guide.

Everywhere he stepped was a sight or a delicacy.

They were so well prepared that they unpacked their luggage in the hotel room in no time.

Grrr.

Sun-hoo, who dragged a large suitcase, unpacked the equipment in the hotel seminar room that he had reserved.

The new server and communication equipment that Hyun-jin-geon brought were inside.

Click. Click.

Yoo-hyun admired Sun-hoo, who quickly connected the communication equipment and the server.

“Sun-hoo, you’re really fast.”

“It’s not for nothing that I raised him. The data center maintenance is also running smoothly thanks to him.”

“Why do you seem to like it more than being praised yourself?”

“I guess so. I feel like I understand how you guys feel a little bit.”

Nado-ha, who was lonely in his hard life, received a family-like love from Yoo-hyun and his gym buddies.

Was it because he had a younger brother he cherished?

He felt more grateful for the love of his brothers that he couldn’t understand.

He liked it so much, and he wanted to be nicer to Sun-hoo.

“Son.”

Yoo-hyun looked at his grown-up brother with pride.

He checked the internal internet network in China with the server he connected in the hotel seminar room.

As expected, there was no problem opening the backdoor of Huawei’s communication equipment in the internal network.

But he couldn’t be complacent.

Yoo-hyun and his party traveled around Shenzhen and did the same test.

It was to check if it worked properly on various communication networks.

They deliberately came early and spent about three days to carefully simulate and verify, and they were able to get successful results.

Now all that was left was to access Huawei’s main communication network directly.

The next morning.

A black limousine sent by Huawei was waiting in front of the hotel entrance.

Yoo-hyun and his party got into the car after receiving a polite greeting from the driver.

Yoo-hyun leaned back on the soft seat and looked out the window.

-Huawei Shenzhen Campus.

As they passed under a large sign with an arch, a scenery decorated like a college campus came into view.

The area of the Huawei campus, as it was called, was 2 million square meters, as large as 10 Seoul World Cup stadiums.

In the center of it, there was a 30-story glass building, which was Huawei’s headquarters.

He suddenly laughed as he looked at the tall building.

‘I can’t believe I came this far.’

He used to be oppressed from afar, but now he had a chance to change it himself.

It was an unexpected path.

But since he had set foot on it, he wanted to go all the way.

Wouldn’t he be able to get the results he wanted when he arrived at his destination?

Through this, many wrong things would be corrected.

As he was thinking about this and that, the car stopped in front of Huawei’s headquarters.

Clank.

As he opened the door and got out, Woo-jung-cheol, the vice president who had arrived earlier, greeted Yoo-hyun.

“Oh, Mr. Han, I’m so glad to see you here.”

“If you were here earlier, you should have told me. Then we would have hurried up.”

“Don’t mention it. I was talking to an old partner and didn’t notice the time. Let me introduce you. This is Zhao Zhi, the director of global sales at Huawei.”

Woo-jung-cheol, who smiled brightly, pointed to the man behind him.

A middle-aged man with a neat outfit and sharp features greeted him in English.

“Hello, Mr. Han. I’ve heard a lot about you. You worked at Hansung, right?”

“Yes. That’s right.”

“Haha. I supplied a lot of equipment to Hansung Telecom. This is also fate.”

“…”

It might have been a friendly remark from Zhao Zhi’s point of view, but it was a bitter thing for Yoo-hyun.

‘How much I suffered because of these two bastards’ collaboration…’

Yoo-hyun suppressed the sudden irritation and forced a smile.

He couldn’t ruin the job with such a trivial emotional control.

The awkward atmosphere was settled after Hyun-jin-geon and Nado-ha greeted him.

“Let’s go in.”

Yoo-hyun followed Zhao Zhi’s guidance and stepped into Huawei’s headquarters.
