Upon seeing that figure, a strange light flashed in the eyes of the two men, and then they spoke respectfully.

“Miss Uesugi Sakura.”

"you…"

The voice was clear and crisp, carrying a hint of childishness and curiosity: "What happened between you?"

"Sorry, we don't understand what you're saying."

Fuma Megumi gave Inuyama Ryota a look, then politely said goodbye: "It's getting late, you should get some rest too, we'll take our leave now."

Without giving her a chance to stop, the two quickly left the Uesugi family home.

Sakura Uesugi was left staring at the two figures with a puzzled look on her face. It was the strange thing she had noticed earlier that made her question it.

It wasn't that she was questioning them, but rather it was a habit; the girl first questioned whether she had misread the image.

"Miss Yingli, it's time to rest." A maid came running over, her head down, not daring to look at the girl's back.

The girl stepped out from the railing, her feet lightly touching the wooden floor like a butterfly, yet with a childlike playfulness. She hopped a couple more times, but without any elegance.

"Sister Yu".

The girl squatted down, and her hand supporting her chin caused her clothes to slip down, revealing her excessively white arms.

But Uesugi Yuran didn't dare to linger, and forced a smile when their eyes met for a moment: "Miss Yingli, what's wrong?"

Uesugi Sakura didn't speak, staring into her eyes for three seconds, and only looked away after confirming something.

She stood up, her voice barely concealing a hint of joy: "It's nothing."

This joy was somewhat complicated; it wasn't because of friendship, respect, or even love.

It was simply because those two people looked at him as if he were an ordinary person, without fear or prejudice.

It was merely a matter of verbal respect.

Uesugi Yuran breathed a sigh of relief, finally able to put her mind at ease.

Watching Xiao Tiao's departing figure, her eyes were filled with fear, as if she were looking at a different person.

In fact, no one in the Uesugi family, including those in the know, would consider her human.

...

Meanwhile, Inuyama Ryota and his companion had returned home and happened to see Qin Sheng and his companion having dinner.

"Well done, just wait and see."

Qin Sheng had already seen Uesugi Yukawa taking the medicine through their eyes, and at this moment, another red dot appeared on the system.

"Who is this Uesugi Sakura?" Qin Sheng asked with some interest.

The two of them may not have observed very carefully, but Qin Sheng noticed that the girl had many small scars on her body, resembling injection marks.

It's obvious he gets a lot of injections regularly.

At the same time, their attitudes were also off.

“She is Uesugi Sakura.” Fuma Megumi paused for a moment and explained, “She is currently the only person who is 100% compatible with the enhancement potion.”

“100% perfect match.” Qin Sheng raised an eyebrow.

The so-called enhancement drug is a product of the genetic experiments conducted in Flying Cherry City.

But this thing is completely defective.

The scientists in Flying Cherry City weren't fools. After the previous cases of intelligent beasts, they stopped trying to control them and instead chose to put the power of the beasts in human hands.

The simplest method is to extract the spinal fluid or similar products from the alien beast and inject them into a person's body.

Of course, direct injection is impossible.

After a long period of research, they processed and diluted the spinal fluid in various ways to create a strengthening agent.

In the initial experiments, only one out of a hundred people did not explode directly with the drug.

Countless more people sacrificed their lives in the process, but finally a set of qualified testing standards was developed.

But as mentioned earlier, the enhancement potion is an incomplete product.

The first issue is the selection of personnel. Fei Ying City still doesn't understand the principle behind compatibility; it's just an evolutionary judgment based on the degree of fusion between blood and enhancement potions.

Even so, people still occasionally cause explosions.

Secondly, regarding strength, the enhancement effect of the strengthening drug injection on martial artists is not significant.

If a first-level martial artist were to receive the injection, they would normally be able to withstand the attack of a first-level beast for half an hour, but they would probably only be able to last for another half a minute.

The premise is that everyone is wearing weapons; without them, they still can't withstand more than a few moves.

Not to mention that as one's cultivation level increases, the rate of improvement becomes even more negligible.

Fei Yingcheng's solution was simple and crude.

Increase the dosage!

This method did make the increase in drug efficacy more obvious, but at the same time, side effects also appeared.

Excessive use of the drug can cause a person to become extremely irritable. The more the drug is injected, the closer the person becomes to a powder keg, eventually leading to a complete loss of reason and resembling a monstrous beast.

Of course, according to the announcement from the laboratory, stopping the injection before the critical point will allow one to maintain their sanity and gain even greater power.

Qin Sheng remains skeptical about this.

It wasn't that he didn't trust the scientists in Flying Cherry City, but rather that he knew that once genetic modification began, it was impossible to stop.

The amount of enhancer can only affect the speed of the process, not eliminate it.

"100% compatibility?"

Qin Sheng squinted. Didn't this mean that the enhancement potion could completely fuse with Uesugi Sakura's blood, becoming indistinguishable from it?

Is that Uesugi Sakura even human?

His gaze swept over the people present.

Qin Sheng shook his head and smiled.

From a genetic perspective, everyone present, including himself, wasn't actually human...

There's no point in dwelling on this question; on the contrary, Uesugi Sakura is of great research value!

She is different from Qin Sheng and the others; she may truly possess the ability to master the characteristics of alien beasts without needing the potions provided by the system!

"Humans are indeed amazing creatures."

Qin Sheng sighed and continued, "Do you have any information about her?"

Fuma Megumi shook her head: "The information about Uesugi Sakura is top secret. We only know that she is compatible with the enhancement potion and that her strength is terrifying."

Ryota Inuyama nodded in agreement: "It was also because of her that I had previously imagined that the compatibility with the enhancement potion might be very high."

Such valuable talent could not possibly be put into the public eye so easily. It turns out it was a marketing tactic to attract members of the Orochi family to come and test their compatibility, thus making them guinea pigs.

However, this may not be the whole story regarding Uesugi Sakura's current special status, as the researchers are unlikely to release all of her information.

With a hint of anticipation, Qin Sheng said with satisfaction, "It seems there's an unexpected surprise."

Clearly, he has included Uesugi Sakura in his future research.

"Next up are you guys."

Two vials of medicine appeared on the table, and Qin Sheng said calmly, "These are medicines to enhance your strength."

Excitement flashed in their eyes as they took the weapon and plunged it into the neck.

They didn't even look at the two of them; it was just an enhancement of their characteristics, a pattern that had already been established.

Now is not the time to destroy them at will.

We should wait until Genzo becomes a believer and is able to deal with the corpses before making any decisions.
