Jiang Cheng returned home and went straight to the laboratory. He glanced over and found Guan Xiaofei and Su Qianqian busy in their small laboratory, which made him smile happily.

Since these two sisters gave up their current jobs to help Jiang Cheng, they've shown their individual talents and have been working diligently and earnestly, something Jiang Cheng found quite amusing.

Jiang Cheng thought for a moment, then promptly opened the door and walked inside.

Both were wearing simple white lab coats, yet their figures were quite good. Even in lab coats, they looked attractive, which was pleasing to the eye.

The two were engrossed in their work, unaware that Jiang Cheng had already entered.

Jiang Cheng approached Guan Xiaofei, took a look, and couldn't help but nod. The project he gave the two sisters might be child's play for Jiang Cheng, but for them, it's not a simple matter.

As of now, Guan Xiaofei was already close to a complete solution.

He walked over to Su Qianqian, who was conducting an experiment.

Jiang Cheng noticed this and slowly furrowed his brows. He discovered Su Qianqian had a bad habit, and there were significant issues with her experimental procedures.

Without much thought, Jiang Cheng approached and said, "There's a bit of a problem."

"Hmm?" Su Qianqian was stunned for a moment. Upon hearing a voice, she was startled and looked over to find Jiang Cheng. Her expression turned joyful, and she quickly asked, "What's wrong?"

"There are too many errors," Jiang Cheng said and then reached from behind Su Qianqian, taking her hand to lead her properly.

Jiang Cheng had done this many times, not thinking much of it, and acted without any ulterior motive.

However... for Su Qianqian, it was different.

Jiang Cheng held her hand from behind, leading her to lean completely against Jiang Cheng's chest. This sensation made Su Qianqian blush slightly, feeling embarrassed yet a bit strange, with subtle and complex emotions—a bit happy and somewhat sweet.

For a moment, Su Qianqian felt a sense of springtime in her heart.

Having interacted for this long, Su Qianqian couldn't help but admire Jiang Cheng—so perfect, so handsome, knowing so much, like a towering mountain introducing her and Guan Xiaofei to a broader world. More experiences, more than the ideal prince she yearned for in her dreams; it's only natural for her to secretly like him.

At this moment, being embraced from behind by the admired person—how could she not be happy!

Of course, Su Qianqian knew that Jiang Cheng might not have any other intentions, but even so, she was very content!

A sweet smile appeared unnoticed at the corner of Su Qianqian's mouth.

Jiang Cheng naturally noticed Su Qianqian's thoughts and said with a sigh, "Don't get distracted."

"Alright." Su Qianqian nodded slightly.

"Observe carefully what I'm doing and note every step. First, you should..." Jiang Cheng slowly spoke by her side.

Su Qianqian listened intently, touched by Jiang Cheng's attentive one-on-one guidance—a meticulously thoughtful teaching, yet the opportunity was rare—moreover, she decided not to wash her hands tonight! To savor the feeling of Jiang Cheng holding her hand!

Not far away, Guan Xiaofei, who was resolving problems, heard the conversation and looked up. Seeing this scene, her eyes widened in slight surprise.

This pose... was indeed too close.

Qianqian's body was completely glued to Jiang Cheng!

She watched, cheeks flushed, but... if it wasn't Qianqian standing there, but herself, how wonderful would that be!

Jiang Cheng helped Su Qianqian resolve the issue and then approached Guan Xiaofei.

Guan Xiaofei, seeing Jiang Cheng approaching her, quickly lowered her head like a startled little bird.

He patted Guan Xiaofei's head and said, "That's a good idea. Solve all the problems I left you with, and then come find me.

"Hmm..." Guan Xiaofei sounded like a mosquito.

"It's good to know this." Jiang Cheng really heard it and nodded in response.

Then Jiang Cheng turned around and left—to start his own work.

After Jiang Cheng left, the two sisters exchanged glances, understanding each other's thoughts without speaking...

Perhaps this is "speechless!"

For most ordinary people, it's hard to imagine how they would feel when they research and create a truly meaningful Virtual Reality Device.

These two achievements are enough to make anyone proud for a lifetime. It can be said that Virtual Reality Devices have changed part of human life.

As individuals, achieving this is very great. Most human life is merely for survival, even though there are extraordinary events, they are not significant in front of the entire human hierarchy, such things happen every day.

Essentially, changing the entire human hierarchy or similar things is unrealistic.

But everything is moving smoothly—Jiang Cheng is gradually changing the world, influencing all of humanity.

He didn't become complacent because of current achievements, as complacency is not worthwhile; he considers it as a matter of course.

Similarly, Jiang Cheng doesn't know how advanced future civilizations and technological levels will be. Even though he learned the truly meaningful Virtual Reality Device from the Black Technology System, he won't be proud of it.

Because this is given by the system.

Why should one feel proud about it?

Should he feel proud about it? Is this all there is?

Due to the influence of such emotions, Jiang Cheng, who is changing the whole world, now feels very calm and is thinking about what to present next to change humanity?

Jiang Cheng has many ideas, but not many are suitable for this world—of course, for people in this world, the number is quite considerable, but when these things are presented, attention should be paid to the order.

Human technology is like a tree; he must consider balanced development. If misaligned, it can easily lead to unfavorable consequences and difficulty in resurgence.

The current question is simple: what kind of technology should he present next?

Jiang Cheng thought carefully, rubbing his brows, when suddenly the computer screen beside him turned on, and Lucy, the Artificial Intelligence created by Jiang Cheng, appeared on the screen. She looked at Jiang Cheng and asked, "Master, you look like you have a headache, have you encountered something troubling?"

"It's not a problem, just thinking about what else this world needs," Jiang Cheng said, shaking his head.

"What do people in this world need?" Lucy paused for a moment, then immediately replied, "People in this world are lacking a lot. The poor need money, the hungry need food, the lonely need company, those who are confined need freedom—too much, don't know what the master means."
