Nerve Reaction Potion was a genetic potion that could strengthen the human nervous system and make one's neural responses sharper.
The Basic Nerve Reaction Potion of the fifteenth year of the apocalypse could only improve this by 6%, but this potion from fifteen years before the apocalypse could raise it by a full 30%. Compared to it, it was practically no less effective than the frail, comprehensive perfect-type potion among the First Generation Nerve Reaction Potions.
After the apocalypse, because of the problem of reproduction, all technology had tilted heavily toward biological Gene Technology, so Genetic Potion development progressed extremely rapidly.
People collectively referred to the levels achievable by the various Genetic Potions from before the apocalypse as Basic Genetic Potions.
The potions from the first technological iteration were called Level 1 Genetic Potions; those from the second iteration were called Level 2 Genetic Potions.
And so on. It was said that the most cutting-edge research laboratories had already achieved a milestone breakthrough with the potions of the seventh iteration—the Level 7 Genetic Potions.
Among the Genetic Potions currently fully developed and in use, the most advanced Sixth Generation Genetic Potions could already push the human body to a terrifying level, allowing it to withstand a nuclear bomb head-on.
On the rooftop, after hearing the shocking news that the humans of this world could no longer reproduce, Li Yang had been stunned for a while. Now, he had calmed down and begun taking the second bottle of Genetic Potion.
The news that the humans of this world were destined to perish if they could not break free from the shackles of reproduction truly left him stunned and incredulous.
But as far as he himself was concerned, there was simply nothing he could do about such a matter for now. It was a topic far too distant from him.
Even if he wanted to do his part to save the humans of this world, which had provided the foundation for his life, he could not help much.
Besides, to put it coldly... even if every person in this world died, what did that have to do with him?
At most, it would simply become harder for him to obtain more resources in the future.
But what he had gained so far was already enough for him to establish himself on Earth, wasn't it?
Moreover, even without humanity, this world would still remain. By then, it would still be his own backyard...
Thus, Li Yang had no worries at all. After his brief bewilderment, he put the matter out of his mind and took the second tube of Genetic Potion.
If most of the people in this world can't do anything to help with this matter and only care about indulging themselves, what can I possibly help with?
With that thought flashing through his mind, Li Yang took the second potion without a trace of guilt—the purified version of the Nerve Reaction Potion that had been called Nerve Reaction Potion Number Three before the apocalypse and was now collectively known as a Basic Potion.
"Phew~"
Unlike the previous potion, this tube did not make Li Yang feel any heat after he swallowed it. Instead, he felt a chill.
The sense of emptiness found in the silent void of outer space spread from his brain, making Li Yang's pupils contract.
"Why do I feel this emptiness and loneliness, as if I'm surrounded by darkness?"
Li Yang swallowed, then looked at the female slave, Chang Yanyan, who had already put her clothes back on. Enduring the unease in his heart, he asked her in a deep voice.
"Um, Master, that's a normal reaction. After taking the post-apocalypse Basic single-effect Nerve Reaction Potion, a person's emotions will erupt intensely. The pre-apocalypse version merely randomly amplifies a particular emotion. It doesn't count as a side effect."
Chang Yanyan froze when she heard Li Yang. Blinking in confusion, she asked, "Is there a problem... Master, if you're feeling uncomfortable, you can hug Yan Yan."
As Chang Yanyan spoke, she realized that her master was currently in a heightened emotional state. She hurried over to Li Yang, considered his loneliness for a moment, then gazed at him gently and spoke in the sweetest voice she could.
"Do I need to remain still for the entire duration of the potion's effect?"
Li Yang breathed deeply, the feeling of loneliness surging uncontrollably through his heart. Looking at the female slave who had come before him, he restrained that sensation and asked his question in a deep voice.
"No, you don't. Feeling emotionally uncomfortable right now is normal. It'll be fine once the potion's effect ends. You can hug Yan Yan and soothe your emotions."
Chang Yanyan paused, then immediately shook her head and spoke gently to Li Yang.
"No need."
Li Yang continued taking deep breaths to resist the loneliness in his heart. He turned around, wrapped the tight-fitting suit—which bore no markings but could no longer be worn—around his buttocks, and put on his exoskeleton.
"Have Yu Dong prepare the Micro Smart Brain we bought. Take the machine back. Wait here together tomorrow morning. I'll come again."
Li Yang gave Chang Yanyan an order, then immediately turned and charged toward the neighboring building. After a few running leaps, he vanished from Chang Yanyan's sight.
Chang Yanyan stared blankly in the direction where Li Yang had disappeared, then shook her head. She guessed that her master had surely gone to look for his former friends or women. Muttering to herself, she cleaned up the traces at the scene, put on her own exoskeleton, picked up the detector beside her, took Li Yang's drone, and ran toward their residence.
His original purpose in having Yu Dong return for the Micro Smart Brain had been to send away the male who appeared to have greater combat strength, avoiding any accidents during their first close contact. After all, even control through the Slave Wristband Controller required human reaction time. If the two of them suddenly erupted at close range, he might have stumbled into a serious setback.
But he had not expected these two slaves to have been harboring such sinister intentions from the very beginning. Later, when he had undergone such an intense evolution, Yu Dong had been afraid of disturbing him and Chang Yanyan, so he had never come.
However... the Micro Smart Brain truly was a good thing. With it, he could better spread his wings, which was why he had specifically summoned him back again.
"..."
The Real World.
"Vrrr..."
The engine emitted a lively bass rumble. With a bath towel and clothes wrapped around his body to cover himself, Li Yang drove toward the villa.
Watching the traffic flowing ahead, he felt the loneliness brought on by the potion surge through his heart in waves.
It was fairly intense, but still within a controllable range.
That woman had been right. He truly did want to hug a woman.
But the woman he wanted to hug was not Chang Yanyan. It was... Chen Qian.
It was a little strange. Li Yang could not explain why. Perhaps it was because this girl was the first woman he had touched in the past few years. Perhaps it was because she was the first woman he had obtained after his life began to rise. In short, she was his first woman in a certain sense.
Perhaps it was also because her delicate body had left a deep impression on him, and her docile appearance had entered his mind day after day.
Perhaps it was the sight of her fair, tender body when he woke early that had moved him. Perhaps it was because he had taken her back to his old hometown once.
In any case, the person Li Yang now wanted to hold in his arms was Chen Qian.
"Too slow..."
Li Yang frowned at the traffic ahead. Suddenly, he felt that both the surrounding cars and his own vehicle were moving far too slowly. He could not help increasing his speed until he reached the speed limit, then silently eased off the accelerator. After that, he maintained the speed limit and drove toward the villa where he lived.
Soon, he arrived at the villa. After parking in the designated spot, Li Yang quickly entered the building.
"Brother Yang."
Chen Qian was sitting in the study, wearing simple clothes as she studied. Li Yang found her by following the scent. When she saw him suddenly return, she froze. Then Li Yang grabbed her from the chair by the backs of her knees, lifted her away from the seat, and threw her onto the bed.
"Ah~"
