"However, the effect of repeated use of the same type of medicine will be blunted, and after more than 100 of the same type of medicine are used, all medicinal power will be lost!"

"And the side effects of the drug on the human body are also relatively obvious, and the interval between uses must be increased according to the multiple, and it cannot be used frequently!"

Qin Xuan muttered secretly in his heart: "Lao Tzu doesn't want to be crippled by you. ”

System: When the gene enhancer was developed, it had been tested on mice more than 15 times, and only after confirming the safety would the computer simulation human test be carried out, and the experimental data would be transferred to the human body after the safety was confirmed.

Qin Xuan asked, "Then how was her previous eldest sister disabled?"

System: It is very likely that the user's use method is not standardized, and some people often forcibly use the drug during the buffer period of the drug injection in order to quickly improve their own strength, which will lead to unpredictable consequences!

System: The encyclopedia shows that the disability of drugs is not accidental, the frequency of occurrence is quite high, but basically it is not fatal, compared to the huge benefits it brings, a little pain is still worth it.

Qin Xuan muttered secretly: "Let's go over in person, I don't want to joke with my own little life!"

With a flash of white light in front of him, Qin Xuan's body quickly teleported to the shore of a lake in Zichen Xing, where Shirley was sitting on a small bench fishing.

Qin Xuan ran over and glanced at her small fish tank, and found that the fish in the fish tank were all small white fish more than an inch long...... It's full of thorns.

"I've been busy for a long time, just this little harvest?" Qin Xuan grinned and said, "If you want to eat fish, wouldn't it be fragrant to buy a fish?"

Shirley decisively refused: "It costs a lot of money to buy fish, and you don't need money to fish by yourself!"

Qin Xuan replied with a wry smile: "The key is that this kind of little white fish can't be eaten, there are no two taels of meat on the body, and all of them are small thorns that can't be spit out." ”

"I didn't eat it myself, I can take it back and feed it to the iron-mouthed beast!"

Speaking of this, Shirley even took out a shot of medicine from her arms and handed it to Qin Xuan: "This is the gene enhancement medicine you want, do you need me to inject you on the spot?"

"Just here for the injection?" Qin Xuan glanced at the bustling crowd around him, his forehead was about to twist into a line.

Shirley said insignificantly: "It's just a needle in your arm, not a punch in the buttocks, what are you excited about!"

Qin Xuan also briefly searched for the information circulating on the Internet before, the gene enhancement medicine is not a dangerous medicine, and there is no harm to the human body, unless you are looking for death by yourself, and serious overuse is another matter.

If you simply compete in physique, humans and beasts are not on the same level at all.

Even the weakest Tiger Emperor in the beast clan had a height of hundreds of meters and a huge body of tens of thousands of tons, while Qin Xuan was a "little man" who was less than two meters tall and weighed less than 100 kilograms, and the difference in body size was simply a natural difference.

If you simply compete in strength, even if 1,000 Qin Xuan are combined, it is impossible to be the opponent of the Tiger Emperor.

Qin Xuan was able to defeat the Tiger Emperor twice, not by physical strength, but by suppression in terms of weapons and equipment.

But Qin Xuan also knew very well that the reason why the Tiger Emperor and they would be "suppressed" by their own equipment and potions was mainly because of information asymmetry.

Qin Xuan could freely contact the outer universe through the Wanjie Taobao network, and purchased a large number of advanced equipment and medicines, but the Tiger Emperor was locked in the wild world and could not communicate with the outside world.

If he encounters an enemy outside the savage world, Qin Xuan's equipment and potion advantage will be gone, and he may be "suppressed" by others.

So if you want to make up for the gap, the best way is to use potions to enhance your physique.

After some simple consideration, Qin Xuan accepted Shirley's proposal: "Okay, you can help me inject the gene enhancement potion now!"

A few minutes later, Shirley injected a jar of potion into Qin Xuan's body with a syringe.

After the potion entered his body, Qin Xuan only felt a sense of coolness permeating his whole body, and he felt that his whole body was relaxed physically and mentally all at once.

Shirley continued: "The genetic enhancement potion will increase your physical fitness by 198% in the next 7 days, and after 7 days, after the medicine is completely consumed, you can inject the second injection!"

Qin Xuan could also vaguely feel that a powerful medicinal power was constantly washing his body, and his physical fitness was constantly getting stronger.

System: The Apothecary's Elixir has the same effect as the Apothecary's Elixir, but the physical way of existence is different.

System: After the eldest sister uses up 100 injections of genetic enhancement potion, her physical fitness will be strengthened to 1% of the level of the Tiger Emperor.

"What?" Qin Xuan couldn't believe his ears a little, "I used up 100 injections of genetic enhancement potions to be able to have 1% of the Tiger Emperor's physique, how do I feel as if I am weak?"

System: The Tiger Emperor's IQ is only 35, and the eldest sister's IQ is as high as 91, which is almost three times that of him!

Speaking of which, Qin Xuan only had one sentence left to "hehe".

The Tiger Emperor's physique was tens of thousands of times stronger than his own, if Qin Xuan didn't have a slight IQ advantage, wouldn't he just have a dead warp?

After the successful injection of the gene enhancement agent, Qin Xuan's Wanjie Taobao website data table added another "potential index" data table.

There are three potential indexes, namely: Strength Index, IQ Index, and Development Index.

Qin Xuan's strength index is 17, his IQ index is 91, and his development index is 65.

"That's right!" Qin Xuan was very satisfied with the effect of the gene enhancement potion.

But Qin Xuan didn't just come to Shirley this time for this.

"Do you have any powerful lethal potions here, give me a batch, I've met some powerful opponents recently!"

Shirley shook her head and smiled: "Potions above level 12 cannot be developed and manufactured in the planetary realm, if you want to develop high-level potions, you must build me a scientific research station in the universe void, or build a manor of independent time and space!"

"Potions above level 12, the lethality is too terrifying, once an accident occurs, the whole planet will be buried with it, and once it is detected and developed privately, it will definitely die!"

Pharmacists are a very dangerous profession.

Without any management restrictions, it only takes a level 7 pharmacist to easily pollute and destroy a planet.

Not to mention the existence of Shirley, a level 13 (holy level is also known as level 13).

Every pharmacist is closely monitored by the planet's governing body, and some lethal potions cannot be taken out of the laboratory at will.
