This is still the effect of the primary level. The difference between the primary and intermediate, although just one level apart, is vastly different in terms of effect.

The Intermediate Gene Potion enables human genes to reach a perfect state, extending lifespan from a thousand to fifteen hundred years and enhancing strength, speed, agility, and overall physical condition.

Additionally, genes will evolve and awaken some extraordinary abilities.

Everyone's ability is different; the Neo-Humans propelled by genetic evolution are akin to the "superpower" characters in novels, separating them entirely from ordinary humans in terms of combat power.

Achieving this level represents the limit of current technology.

Pushing genes further requires civilization to reach a higher level, but Earth's civilization is still far too low—Jiang Cheng can barely apply only one percent of the knowledge and technological references in his mind!

During a break from experimental research, when Jiang Cheng was resting, Xia Xiaowei keenly noticed that Su Qianqian and Guan Xiaofei had disappeared from home, and curiously asked, "Where are Guan Xiaofei and Guan Xiaofei? Why aren't they here?"

Jiang Cheng shrugged his shoulders and said, "They are undergoing a transformation."

Now Xia Xiaowei can barely be considered a trustworthy person. Having chosen Xia Xiaowei as his secretary, Jiang Cheng doesn't mind sharing some of his secrets with her.

On one hand, Xia Xiaowei is extremely passionate about her feelings for Jiang Cheng; on the other hand, Jiang Cheng is not afraid of Xia Xiaowei's betrayal—simply put, he is powerful enough, in various senses, compared to ordinary Earthlings!

"A transformation?" Xia Xiaowei was stunned by Jiang Cheng's words, and curiously asked, "What kind of transformation?"

"A genetic transformation," Jiang Cheng did not hide the truth: "You'll see them in a couple of days—"

Jiang Cheng smiled but did not elaborate.

Hearing this, Xia Xiaowei's body trembled, her pupils slightly contracted, and her eyes were filled with disbelief!

Although Xia Xiaowei had guessed that Jiang Cheng might have made some progress in terms of genetics, she hadn't anticipated that Jiang Cheng's achievements could already be applied to the human body.

She knew very well what this meant: the world would change because of it, a new era...was about to arrive!

Thinking about this made Xia Xiaowei's scalp tingle. During this period, around the globe, on major news media outlets, discussions about Jiang Cheng's speech have not ceased.

From forums and discussion boards to self-media comment sections, debates over Jiang Cheng's speech have erupted constantly, yet no one has produced a definitive answer.

Jiang Cheng, at the center of this matter, has not spoken yet! His attitude and subsequent statements are crucial, and the lack of response has left many frustrated and curious, wondering whether Jiang Cheng has things well planned or if he truly lacks substance?

It is imaginable how much of a stir Jiang Cheng's publication of his results will cause!

And now, Xia Xiaowei is the first to know this news; she deeply understands the weight of the news—this kind of news was casually revealed to her by Jiang Cheng!

Xia Xiaowei couldn't help but feel touched, Jiang Cheng actually trusted her that much!

Xia Xiaowei opened her mouth, ready to say something or ask further, but quickly realized Jiang Cheng seemed not to want to elaborate, so she hesitated and closed her mouth.

Some questions must be asked, while others absolutely should not be asked—this must not be forgotten.

The entire world, stirred by Jiang Cheng's speech, faced continuous turmoil; many ridiculed Jiang Cheng's naivety, while quite a few supported him, mostly hoping to see him produce new achievements.

However, Jiang Cheng, the person in question, has not shown any awareness of being the center of attention and, since the end of his speech, has quietly conducted research and experiments.

The ridicule and expectations from outsiders seemed irrelevant to him.

Before developing the Intermediate Gene Evolution Potion, he doesn't plan to show himself again.

That is to say, since that speech, he has vanished from the public eye and has not reappeared!

This made many anxious.

But everyone was helpless.

While Jiang Cheng worked on research experiments, Guan Xiaofei and Su Qianqian finally awakened...the sisters awakened on the third day just like Jiang Cheng.

The sisters, upon awakening, looked at each other confused, only realizing what happened after a while...

"Go wash up," Jiang Cheng came to them first, looked at the sisters, and said with a smile. Shoes.

"Hmm," the sisters nodded and promptly went to the bathroom to wash off the impurities expelled during their evolution.

Soon, Guan Xiaofei and Su Qianqian emerged from the bathroom wearing loose white bathrobes, and their transformation made Jiang Cheng's eyes light up.

Originally, Guan Xiaofei and Su Qianqian's aptitude and appearance were exceptional, but now, enhanced by the Genetic Evolution Potion, it was as if their last imperfections had been turned into perfection; at this moment, Guan Xiaofei and Su Qianqian's beauty could be said to be stunning beyond compare.

Despite wearing simple and plain bathrobes without any fancy designs, they still appeared beautiful and captivating, with a hint of fair skin visible between the loose fabric, causing Jiang Cheng to feel somewhat swayed. The bathrobes were so loose they seemed ready to fall off at any moment, further enticing Jiang Cheng to want to explore and delve deeper.

Additionally, since they had just bathed, water droplets were visible all over Guan Xiaofei and Su Qianqian, their fair and rosy skin seemed extremely delicate, and even Jiang Cheng couldn't help but be momentarily stunned upon seeing this sight.

But, almost instantly, Jiang Cheng came to his senses, as the sisters, even if in a previous life, could be considered stunning beyond compare; however, Jiang Cheng was not an ordinary person, naturally, he wouldn't completely freeze, and soon asked, "How do you feel?"

The sisters, freshly washed and rid of all impurities, glanced at each other as if looking into a mirror, both surprised by each other's beauty—at that moment, they realized that since their sister's appearance had changed like this, they themselves must have undergone similar transformations, which made them quite happy.

At this moment, the sisters listened to Jiang Cheng's question, looked up, and quickly replied, "We feel great...

Guan Xiaofei, looking at her hand, arm, and seemingly a slightly bigger bust, couldn't put into words her joy, and she excitedly said, "No, it should be feeling very, very great. I feel full of endless energy all over, and my skin, my eyesight, my strength, they all seem greatly enhanced—is this the effect of the Genetic Evolution Potion? It's so incredible! I can't believe this is just the primary level. If this is the primary, then how powerful would intermediate or advanced be!"

Su Qianqian, equally astonished, said, "It feels like I've been reborn; sister has become so beautiful, and I seem to have experienced similar changes..this is wonderful.

"I'm glad you feel good," Jiang Cheng smiled and said, "Let me take a closer look at the specific changes in your bodies.
