The new finished potion did not lose the effect of strengthening the body, which made Aaron feel a lot more relieved, at least it proved that the mutant thorn vine could still replace the bloodthirsty vine and be used as a material for making potions.

Since the agent is effective, the next step is to observe the side effects, the original drug, starting the day after taking it, will have the effect of side effects, mainly manifested as severe pain twice a day, and irregular short-term weakness for a period of one month.

In the entire series of potions, the first potion has the weakest strengthening effect and the lowest side effects, and the subsequent potions, as the potency increases, the side effects will also become larger and last longer.

The time for the effect of the new finished drug has been significantly delayed, and as for the problem of side effects, it has not appeared for the time being, but this does not mean that there are no side effects, and it may have been delayed.

After confirming that the new potion also had the effect of strengthening the body, Aaron made several new potions, and once again brought the nine-headed beast as an experimental subject, fed the potion and locked it up for observation.

After all, one test subject does not represent everything, and only after the verification of multiple test subjects can we make a certain conclusion.

Soon, a week passed.

"Aren't there any side effects?" After observing the ten little beasts for a week, there has been no side effect effect, and the signs of life of those little beasts have been in a stable state, and their bodies have gradually strengthened over time.

A week is a long time, and in general, the side effects of the drug will appear within a few hours to a few days of use, and the longest period will not exceed a month.

It's been a week now, and there are still no side effects, and Aaron can't help but wonder if the side effects have gone away! If so, then he can be considered a blind cat and a dead mouse.

Suddenly, an idea appeared, but the problem of side effects was solved by mistake, which is simply the favor of Lady Luck!

Although Aaron is a little excited now, he doesn't dare to make a conclusion, it's only a week, and he needs to observe and see, at least wait for a month before he dares to make a preliminary conclusion.

If there are still no side effects at that time, then there is a ninety percent certainty that the drug really has no side effects.

Before you know it, it's been a month!

"Haha! Looks like I'm really lucky this time!" During the month-long observation, Aaron prayed every day with apprehension and his heart that there would be no side effects, and it really made him get his wish!

In the past month, none of the ten small beasts that have been tested have any abnormalities, their vital indicators are very normal, and the potion has passed a few days ago.

Since the effect of the drug has expired and the side effects have not yet appeared, it is almost certain that there are no side effects at all.

After the transformation of the potion, the physical fitness of the experimental subject has been improved several times, of course, this is only the effect of less than one potion, and a complete potion, it will definitely be improved a little more.

Although the physical fitness of the experimental subject is several times that of the original, Aaron is still very clear that if he takes it by himself, it should not have such a perverted effect, because there is still a big gap between his own basic physical fitness and that of the experimental subject.

The weaker the creature, the greater the increase it gets, and this is the case for all potions, because the effect of the same potion is almost the same, and it will not change depending on the individual taking it.

Those creatures that are particularly powerful in themselves will also be strengthened after taking this potion, but on the basis of their already strong strength, the improvement will seem insignificant, or even have no effect.

"To be on the safe side, I'd better wait for another week and make a decision later!"

After examining all the test subjects, Aaron hesitated to drink the potion by himself now, and after thinking about it, he decided to observe it for a while longer to ensure safety, after all, it was better to drink it himself, and it was better to be safe.

Eventually, Aaron waited another week, and none of the subjects showed any side effects.

After such a long period of observation, Aaron felt that the medicine could be taken in person, and the side effects were really gone.

So, he used the remaining materials to make several new finished potions in one go.

"Anyway, I should have a name for this new potion!" After making the potion, Aaron thought about giving this new potion, the original series of potions, there was no name, the new potion was improved by him, and it should have a name.

"What's it called?" Aaron touched his chin, his eyes swayed and thought for a while, and finally thought: "If there is, it will be called the source of life!"

The effect of the potion is to strengthen the body of living beings, which is also equivalent to strengthening the life form, and it is appropriate to call it the source of life.

After choosing the name of the potion, Aaron picked up a potion, poured it directly into his mouth, and drank it all.

After drinking the next potion, Aaron put away the remaining ones for the time being, and then did nothing but sit quietly in his rocking chair and waited.

When the potion was drunk, it didn't taste good, it was like plain water, and it didn't feel anything special when it entered the stomach, but Aaron knew that it would take some time for the effect to take effect.

While waiting, Aaron didn't want to do anything, just let the chip scan his body all the time, and immediately send a warning if anything was wrong.

Time passed little by little, and before I knew it, 17 hours had passed.

It was already noon the next day, and Aaron was halfway back to the lab after instructing Colin, when he suddenly noticed a warm sensation in his chest.

Gradually, this sensation centered on his chest and extended to his limbs, and soon he felt warm and comfortable all over his body, as if he were soaking in warm water.

"Hint! Hint! There are abnormal changes in the main body, the muscle tissue is gradually strengthened, and the body function is gradually improved, and no harm has been found for the time being...... "With the feeling of warmth, it is the prompt sent by the chip.

At this moment, Aaron felt as if he had inexhaustible strength, his whole body was full of vitality, and the corners of his mouth couldn't help but curl slightly: "It's finally started!"

Aaron could feel that his body was getting stronger all the time, but it wasn't obvious, but it would last for a while.

"The strengthening effect of the test subject is close to a month, I wonder how long I will last?" Aaron considered the duration of the drug's effect.
