I really don't want to have a girlfriend.

"Five more minutes? Embarrassing system, just leave the group!" With a disdainful wave of her hand, just then her phone vibrated. Soraji Yu took her phone and lay down on the bed, replying to Natsukawa Masuzu's messages while slowly waiting for the five minutes to pass.

"This guy got caught in the rain, he shouldn't catch a cold tomorrow... or is he deliberately trying to catch a cold?"

After chatting with his girlfriend for a few minutes, five minutes passed in the blink of an eye, and Yuu Tenkuji put down his phone.

"Transaction initiated. The item will appear at 6:00 AM tomorrow."

After such a system prompt flashes by.

As if a vacuum cleaner were constantly sucking away all the blood in her body, Yuu Tenkuji opened her eyes wide in astonishment. As her strength rapidly drained away, the world before her began to blur, and her limbs gradually became weak.

"This...this familiar feeling..."

Am I going to develop kidney deficiency again?!

What exactly did I trade that required so much of my stamina...?

A deep sleepiness enveloped his entire consciousness, leaving only this hazy thought before Tenkuji Yu closed his eyes and fell into a deep sleep.

Hope is a good thing.

—O-juice and the like can permanently seal this state.

Chapter Sixty-Five: The Art Style Suddenly Turned Magical

When Yuu Tenkuji regained consciousness, the first light of dawn was already breaking outside.

He slowly sat up, rubbing his forehead, and first closed his eyes to carefully feel his body's condition—well, apart from being hungry, he felt no discomfort.

It seems that a good night's sleep can fully replenish his energy. The feeling of kidney deficiency he experienced twice yesterday is gone, and he is still full of energy today. Even though he just got up, he still feels like an iron man and doesn't feel tired at all.

"Good morning, bro." Giving a salute to the tent bulging under the blanket, Tenkuji Yu rolled out of bed, looked around the room, and finally fixed his gaze on the computer desk.

Where mineral water used to be, a strange crystal bottle appeared, exuding a mysterious atmosphere completely different from the surrounding scenery, as if it did not belong to this world.

Tenkuji Yu walked over, picked up the crystal bottle, shook it, and could feel liquid flowing inside.

"Is this what I got in exchange for mineral water and my kidney... ugh, my physical labor?"

He didn't open it to smell it, but cautiously asked, "System, explain. Don't tell me I have to guess what this is myself, okay?"

The system didn't reply, but instead, in a very game-like style, a description box appeared next to the crystal bottle.

"Life Elixir: A precious medicine produced in a certain other world. Just one drop can improve the human body and achieve miraculous effects such as prolonging life, beautifying the skin, and curing all diseases."

Note: Only one drop is recommended for the average person. Current capacity: 10/10.

"It's really very concise and clear, just like the instructions on those little ads on telephone poles."

After venting her frustrations, Yuu Tenkuji sat down in her computer chair, examining the small crystal bottle in her hand as she pondered thoughtfully.

There's no need to doubt the authenticity of the explanation; the system has a good reputation in this regard.

Putting aside some strange states for the moment, the physical copies of JOJO's Bizarre Adventure volumes that the system gave him were all of the highest quality in terms of printing, layout, and even the smell of a new book. They were probably even slightly inferior to the volumes that Araki himself received.

In other words, he did indeed obtain a treasure that could only exist in another world, and a very high-level one at that, and the only price he paid was a good night's sleep.

This deal is so good it's suspiciously cheap, I can't help but worry about whether there are hidden traps or if I've actually paid for something else without realizing it.

"System, does this medicine have any side effects? Will drinking it change my gender or grant me immortality or something?"

"There are no side effects, and the effects are only as described in the instructions. The host can take it with peace of mind."

The system reiterated its principle of "never harming the host," and its evolved, gentle voice did indeed put people at ease.

However, Tenkuji Yu still frowned, and after repeatedly confirming with the system like a clingy old lady and asking about all possible loopholes, he cautiously opened the bottle cap and brought his nose close to sniff it.

It has no taste, and the liquid inside is pure white like milk; the neck is very small, probably designed so that only one drop can be poured at a time.

"It should be useful to me too, right?"

"Confirmed. The host's physical attributes have not yet been enhanced to a superhuman level. This medicine can help the host take another step closer to true power, but it is still not recommended to drink more than one drop, as there is a risk of energy excess."

"Will drinking this allow me to use magic?"

"The other world where it was produced does indeed have magic, but before it was traded here, all the magic and side effects associated with this item were stripped away by the system. Currently, it only has basic effects such as strengthening the body."

"That's a real shame... Wait, so this medicine has side effects?" Unable to resist clicking his tongue, Tenkuji Yu said with dissatisfaction, "Damn system, why didn't you just say that from the beginning! The worst thing you can do when processing intelligence is to ignore things that are taken for granted. Although it's not enough to make us afraid to drink it, there's a big difference between being mentally prepared and not being told, okay?"

"..." The system didn't speak, but just listened quietly to his complaints.

Yuya Tenkuji only muttered a few words out of habit before quickly turning the crystal bottle upside down and shaking it into his mouth.

Exactly, a single drop of milky white water detached from the bottle and landed on his tongue, dissolving rapidly.

"Hmm..." Yu pursed her lips and smacked her lips a few times. She frowned and carefully tasted the flavor, but all she felt was a blank. It wasn't strawberry flavor, nor did she feel any heat rising from her body, nor did she feel any black and smelly filth emerging from under her skin.

As he twisted the bottle cap back on, he stroked his chin and murmured thoughtfully, "Is it the delayed-onset type? It feels like I drank a drop of water, nothing changed..."

The system agreed: "The host can treat it as a tonic. Its effects are slow and long-lasting. And because the host is strong and healthy, the benefits that the elixir can bring are much less than those of ordinary people, which is why the sensory effects are relatively weak."

"I see." After thinking for a while, Tenkuji Yu asked, "Can I give this to someone else to drink? Do I have to throw away the remaining nine drops?"

"Confirmed. But no information about the system may be disclosed."

"I know, I know~" Tenkuji Yu waved her hand, looking annoyed by her mother's nagging. "Honestly, no one would believe me anyway, so why are you so afraid of your personal information being leaked? It's really a recipe for disaster."

While muttering complaints about the system, he looked at the 'Life Elixir' with only 9 drops left and already had an idea in mind.

……

Like a legendary elixir or magic potion, a precious medicine that can prolong life and cure diseases, it is now in the hands of Yuu Tenkuji.

Naturally, three thoughts will arise: use it yourself, use it for your family, or sell it.

Fortunately, thanks to the system's unexpected generosity, Yuu Tenkuji didn't have to make a difficult choice; he could even have more than enough to say, "I want them all!"

After consulting the system, he even considered taking a few drops of the elixir and sending them for component analysis—forget about whether it could be replicated, as long as he could make a version diluted tenfold, he could expand his business and reach heights he had never imagined.

But thinking about it is one thing; neither selling it nor sending it for analysis is something I should do right now.

“No one would believe it if I tried to sell it, and there’s no guarantee I could get the same elixir in the future. Explaining its origin would be very troublesome, not to mention that if it gets out of hand, it could affect my family… Sending it for analysis is the same; without my own laboratory and equipment, it’s just asking for trouble. The cost, risk, and benefit are completely disproportionate.”

Therefore, choosing the first two options is sufficient for Yuu Tenkuji.

Around 6:10, he left the room, went to the living room, beckoned the gray-spotted kitten over, and poured some food into its bowl.

"Artoria... no, Xue Nong, your master is giving you an opportunity."

The elixir dripped onto a cat's food. Tenkuji Yu put away the bottle, squatted down, and stared intently at the kitten. He spoke earnestly, "If you can't survive, you'll die; if you do, you'll be reborn… I don't mean to harm you. That guy also said it has the same effect on pets. It's just that I'm a strange person; I don't care about myself, but when it comes to your little mistress, I have to be extremely cautious. Do you understand how I feel?"

"Meow~ (Master, who understands this?)" This is how the kitten answered in the animal language interpretation.

Tenkuji Yu stroked its head, his eyes still gentle, and smiled casually.

"Simply put, let's test the poison on Qiong. Tell me how you feel later, and I'll only dare to use this on Qiong if you're alright."

"Meow~ (I understand, I just need to eat this.)"

Although much smarter than ordinary cats, Xue Nong was not human after all and could not understand his selfishness and obsession. She simply followed his orders and ate the food that was dipped in the elixir, and in the meantime, she finished off all the food in the bowl within ten seconds.

This cat is great in every way, except that it eats as much as the Knight King—in the past, the Sky Temple family would definitely not have been able to afford its food, which would have made their already impoverished family even worse off.

After seeing that it had successfully taken the elixir, Tenkuji Yu didn't keep an eye on it. Instead, he went for a morning run and about an hour later, he carefully inquired about its physical condition and reactions to the elixir, just like a doctor.

"I feel more energetic than before, and my hind legs, which used to be a bit clumsy, have suddenly gotten much better... Is that right?"

After putting down the gray-spotted kitten, Tenkuji Yuu breathed a sigh of relief: "It seems there are no problems after all, so I can give it to Sora now."

"..."

If the system had its own will, it would definitely criticize him now. He's even more cautious than the eunuchs who test poison for the emperor, and he's being overly cautious about his sister's affairs.

However, for Yuu Tenkuji, this was just a coincidence—even if it was produced by the system, he wouldn't dare to directly put the potion from another world into her mouth, so being cautious was only natural.

After confirming the safety of the "Life Elixir" using all available methods, Yuu Tenkuji went into the kitchen and began preparing breakfast.

The next step was simple: in the glass of milk that Qiong habitually drank every morning, he needed to—

"Administer the medicine!"

Chapter Sixty-Six: This plot... cough cough, I've seen it before (6/14)

Sensing a faint noise from the kitchen downstairs, Kasugano Sora awoke from her daze.

"It's already this late..."

He rubbed his eyes and sat up in bed with his silver hair loose.

She stretched and yawned, then lazily turned her head to look at herself in the dressing mirror.

Her petite and adorable face, though not fully awake, held a gentle expression that conveyed a sense of peace simply from hearing that voice.

"It's amazing that Yu can get up this early every day..."

She smiled unconsciously and murmured to herself.

Unlike me, I play games until midnight every day, and I'm always reluctant to get up.

“Hum…”

Kasugano Sora sat on the bed with her eyes half-closed for a while before shaking her dazed head, shifting her bottom to the edge of the bed, hooking out her slippers from under the bed with her fair little feet, putting them on, and then swaying out of the room like a ghost.

After washing up in the bathroom, she was almost fully awake—she would have breakfast and then take a nap before her day officially began.

However, I can't go downstairs to see him looking so disheveled beforehand.

Back in his room, Kasugano Sora sat down at his dressing table and combed his long, troublesome, but beloved silver hair straight.

With two black hairbands tied on, a pair of pigtails hanging down on both sides were formed, looking both cute and playful.

This is also his preferred hairstyle.

In order to make him like her more, Kasugano Sora has been constantly changing herself from the past to the present.

"Okay, is that alright?"

After checking it out as usual and confirming that everything was normal, she left the room with the black rabbit doll in her arms.

Before closing the door, Kasugano Sora glanced back; the dolphin plush toy he had given her was lying alone on the headboard.

If it weren't for the fact that carrying two dolls around was a bit tiring and silly, she wouldn't have wanted to make such a difficult choice.

"Ah~"
