I don't have a system but I have a hammer

My frown deepened...

"Could you please be more clear?"

The old gentleman didn't care about my slightly bad attitude, he just opened the suitcase casually, took out a tube of yellow medicine from it, and drank it in front of me...

"First of all, the medicine itself does have side effects. It will cause the user's brain to be disturbed. In the best case, they will suffer from narcolepsy or insomnia, and in the worst case, it will be... Alzheimer's disease!"

After all, he stared at me like a torch, as if he wanted to get some reaction from me...

However, the only thing that responded to him was my normal face...

That's right, if it's really that serious, he just drank Der, which only shows that there is an incubation period for this side effect...

"Of course, although this side effect sounds terrible, there is actually a safety period, which is about 20 to 25 years. But it should be noted that the longer the time, the more obvious the side effects will appear..."

"In other words, if you can survive 25 years, it can only show that you are lucky, but once this time is exceeded, the prevalence rate is 100%, and it is irreversible!"

Hearing this, I understand why this potion cannot be used by the public, because it is equivalent to letting a person exchange the future for the present. Unless it is an emergency, no one will be willing to use this potion...

But where do ordinary people come from for emergencies?

There are also a lot of special medicines on the market. Although the effect is not that good, at least there will be no side effects...

And the military is even more impossible. If they are marching and fighting, they will either die in battle or lose their combat effectiveness. Even if they survive by chance, there are other hemostatic agents. There is no need to gamble the future...

So this thing is only suitable for people like me who are licking blood with knife-edge and can't openly appear in the hospital...

In other words, only for...lone wolves!

Withdrawing my thoughts, I nodded as if understanding, and asked a few more questions...

"I still have two questions. First, will the amount of dosage used shorten the safe period of side effects? Second, will external use and internal administration affect the safe period?"

It seemed that I was surprised that I would ask such a detailed question. The old gentleman was obviously taken aback, but then he laughed and gave the answer...

"To answer your first question first, yes, but according to our current test results, as long as you don't use it every day, there will be no problem for 20 years..."

"As for your second question, yes, if you take it internally for a long time, the side effects may come earlier, but if you use it externally, the safety period is still maintained at about 20 years. If you only use it once... um... sorry, I don't think you can use it just once..."

Facing his teasing, I didn't care, I just nodded slightly to express my gratitude...

"Okay, then install the mechanical legs for me now, install them earlier, and I will get used to them sooner..."

Seeing that I was so persistent, the old gentleman stopped talking and gave a few instructions to the communicator...

"Ask the medical staff to prepare for the bone implant surgery..."

After all, he got up and made an inviting gesture to me...

"You come with me..."

Glancing at the wrinkled man sleeping on the sofa and the curly-haired man playing games, I nodded slightly and followed the old gentleman's pace...

Two hours later, the operating table...

"Mr. Seven, the mechanical legs have been installed, but now we have a problem, why is there another telepathic signal on your body?"

Seeing the doctor's puzzled expression, I endured the pain at the connection with a blank face, and asked questions...

"Well, yes, that's my left arm prosthesis, what? Will it affect anything?"

Seeing that I had exposed my left prosthetic arm, the doctor looked at it carefully for a moment as if in amazement, and then looked back and answered my question...

"There will be, because in this way, you will have two telepathic signals on your body, one is your prosthetic limb and the other is the mechanical leg, so I need to ask for your opinion now, are you willing to synchronize the two signals?"

I frowned...

"Synchronize or not, what difference does it make?"

The doctor habitually pushed the glasses, then glanced at the computer data on the side, and gave an explanation with a serious expression...

"If they are not synchronized, then the two signals will affect each other, so that when you control the left arm, you will not be able to lift your leg, and vice versa. Although the movement will be uncoordinated, it will have no effect on the body..."

I continue to ask...

"Then what if it's synchronized?"

The doctor shook his head in frustration...

"I don't know, but according to my personal experience, the result of the synchronization may not have any side effects, but it will definitely affect your brain, but the specifics need to be tested after the synchronization..."

Hearing this, I didn't have any hesitation...

"Synchronize, I hope I don't become a fool..."

My self-righteous humor did not infect the doctor, but made him a little apprehensive...

"If something happens to you..."

I casually waved my hand...

"Don't worry, I won't blame you, I will bear all the results alone, you start to synchronize..."

Seeing that I was so persistent, the doctor didn't say anything more, and started operating in front of the computer instead...

At first, I didn't feel anything, just normal, but then for a few seconds, I started to feel dizzy, accompanied by a strange...

Ding ~ Ding ~ Ding ~

Immediately afterwards, the drowsiness in the brain became more and more intense, and even bursts of black mist appeared in front of his eyes, and a strong sense of nausea continued to surge in his chest...

That feeling, as if I suddenly vomited while wearing a deliberate mask, but the vomit blocked the oxygen tube, so I could only swallow it, but because it was too disgusting, I couldn't help vomiting it again came out...

so repeatedly... cycle...

And there was a buzzing in my head, it was more uncomfortable than falling into a cesspit in winter...

hum ~ hum ~ hum ~

And just when I thought I'd get through this stage and I'd be fine, I suddenly felt an eerie vibration, as if someone had pried my brain out and put it in an oversized vibrator for the female titan to play with...

take ~ take ~ take ~

Oh shit!
