An empty room not far from the private room.

The three went inside one after another, with Qin Zhihuai, who was at the back, closing the door behind them.

After waiting a few more minutes, Qin Sheng finally raised her eyes and slowly asked, "Which one?"

Qin Zheng's brows furrowed into a deep frown. He glanced at Qin Zhihuai and Qin Sheng, and after a long while, he slowly spoke: "They say they are the two elders, but I don't know their names."

I've met Qin Sheng four, five, six, and seven times, and I know their names.

However, even Qin Sheng, who had spent half a year in the Black Prison, had never seen Yi Er San. On the contrary, Qin Sheng had seen the legendary Lord of the Black Prison from afar once.

But none of that matters. What matters is...

Qin Zhihuai met Qin Zheng's eyes, his usually lazy voice unusually serious: "What does he want with you?"

Qin Zheng's eyes flickered, but his expression remained unchanged. He simply said, "It's nothing more than trying to win me over. They've done this kind of thing quite often over the years."

But they have never mobilized figures of the level of the two elders.

Neither of them spoke; they simply stared at him intently.

Qin Zheng... Qin Zheng rubbed his temples. Seeing that he couldn't fool them anymore, he could only say in a half-hearted manner, "I have already refused your offer to make a deal with me."

Qin Sheng looked up at him thoughtfully: "What does this have to do with me?"

Qin Zheng: "..."

Qin Sheng squinted at him for a moment, then asked, "Do you want something from me, or do you want me in person?"

What are the conditions?

Qin Zheng: "..."

Hiding it? What a load of rubbish!

Qin Zheng said expressionlessly, "I want a few strands of your hair and a little blood, on the condition that you give me the medicine to suppress my and your brother's illnesses."

He couldn't help but say, "Sheng Sheng, what if, I mean what if, their people come to you and use this reason to force you to make a deal with them? You must not do anything foolish."

Qin Zheng said earnestly, "The people in Black Prison have been completely brainwashed by their warden. They're a bunch of inhuman lunatics. I don't know what they're up to, but their ambitions are definitely significant. Don't listen to them..."

Qin Zheng couldn't continue speaking.

When Qin Zheng met his daughter's "Do you think I'm stupid?" look, his face stiffened, and he couldn't help but slap his face hard.

Sorry, he's the one who's stupid.

Qin Sheng withdrew her gaze and said calmly, "I know what I'm doing."

After thinking for a moment, he rummaged in his pocket and pulled out two tiny black particles, no bigger than sesame seeds. He handed them to Qin Zheng and Qin Zhihuai respectively, casually lying to them, "These are the latest version of the locators I borrowed from the experimental base last time."

Qin Sheng picked up a pellet, glanced at Qin Zheng, then rolled up his sleeve and casually pressed the pellet locator onto the skin near his elbow.

While pressing, he explained, "We use a newly developed skin-friendly material that can be embedded into the skin and is generally undetectable."

As he spoke, he withdrew his hand. Qin Zheng and Qin Zhihuai both leaned over to take a look and saw a small black mole near Qin Zheng's elbow. It looked so realistic that if they hadn't seen Qin Sheng press it in with their own eyes, they would have thought that there was already a mole there.

The two were greatly surprised: "When did the experimental base become so powerful?"

The truly formidable one wasn't the base, but Qin Sheng.

Some time ago, Qin Sheng took on a 500 million yuan order from the base and helped them solve many difficult problems. One of the projects was the research on a new type of positioning device.

Qin Sheng was quite interested and even studied the design himself after helping to create the plan.

She borrowed Qin Yu's private laboratory at the Qin family manor and spent more than half a month improving and creating this thing.

That's all we made.

Qin Sheng had originally planned to sell the technology to the experimental base, but now he had no intention of doing so.

Once this thing is developed by the experimental base, it won't be long before it's released to the public. Once it's released, the Black Prison will know about it, and its secrecy will be greatly reduced.

Their family situation is special, so they really need to have some backup plans.

Well, once I've finished everything I'm working on, I'll have to go into seclusion in the lab for a while.

While Qin Sheng was lost in thought, Qin Zhihuai had already taken the other particle locator from her hand. After thinking for a moment, he looked in the mirror on his phone and pressed the locator onto his face, placing it precisely in the small beauty mark at the corner of his right eye.

The size, shape, and color were all just right, even more concealed than Qin Zheng's at that moment.

Qin Sheng secretly gave a thumbs up to her third brother's wit.

Qin Sheng glanced at Qin Zheng's face, which had regained its vitality but was still paler than usual, and frowned slightly, but said nothing more.

The three of them left the empty room one after the other.

They turned a corner, intending to return to their private room, but instead bumped into a group of people coming from the opposite direction.

Qin Zheng and Qin Zhihuai frowned and simultaneously reached out to protect Qin Sheng behind them.

Only then did he look up at the person opposite him.

The people opposite them were also watching them, their brows furrowed tightly. Especially when they saw the three of them clearly, the leader's face instantly darkened.

"Qin Zheng, it's actually you?"

Qin Zheng recognized the person who had come. He paused for a moment and nodded slightly: "President Zhang."

Mr. Zhang Guangzhong also realized what was happening and gave a polite smile: "President Qin."

Qin Zheng nodded, glanced back at his son and daughter, and prepared to walk around the people back to the private room, but he didn't expect that he would be blocked as soon as he took a step to the side.

Zhang Guangzhong smiled and said, "I had a little unpleasantness with President Qin during the day, but I didn't expect to meet him again in just half a day. I guess it's fate."

"In that case, Mr. Qin, would you do me the honor of having a drink with me, and perhaps we can discuss the Xiang family's new project?"

Qin Zheng remained expressionless, lowering his eyes slightly to look at Zhang Guangzhong: "Isn't the project already settled? If Mr. Zhang feels there's more to say, I think it would be more appropriate to discuss it with the Xiang family head."

"Between us," Qin Zheng smiled and said calmly, "there's nothing to talk about."

Zhang Guangzhong's face darkened.

Meeting Qin Zheng's face, which was both aloof and arrogant, he twitched his eye and said with a forced smile, "I actually think I have a lot to talk about with President Qin."

"For example, the Xiang family's project. Does President Qin really think that your Qin Group alone can handle such a large project worth nearly 10 billion yuan, and that your funds can manage it?"

Zhang Guangzhong said meaningfully, "President Qin, don't try to get rich overnight, you'll overeat."

Qin Zheng's gaze darkened, and just as he was about to speak, the girl's voice rang out from behind him.

Qin Sheng: "My dad has a standard build, but this Mr. Zhang..."

She looked the man up and down, and adhering to the principles of being a doctor, saving lives, and treating everyone equally, she kindly reminded him: "Being overweight is bad. After you get fat, you'll get high cholesterol, high blood pressure, and high blood sugar. Then you'll get blood clots, then cerebral hemorrhage, and you might even get cerebral palsy."

in addition……

Qin Sheng glanced at Zhang Guangzhong's face and shook her head: "Drinking too much alcohol is also bad; it will make you bald."

Zhang Guangzhong: "..."

His face turned from green to white, then white to red, and finally pitch black.
