Floating bodies, strange organs, and some seemingly indescribable substances are enough to make people feel indescribably infiltrating.

But Lin Chen ignored this scene that made many monks feel terrified when they saw it, and walked straight to a row of glass jars.

In this row of glass jars, there are spirit monkeys of similar shape, size, and sex.

One by one, they float in glass jars, their bodies are filled with large and small tubes, and if you look closely at them, you will see that their chests are slightly heaving, and it is clear that they are not dead.

Lin Chen observed carefully for a while, then took out ten spirit monkeys and walked out.

Although it is not clear the origin of the humans in this world, after Lin Chen's observation and research, it was found that the spirit monkey was similar to the monk in both the body structure and the dantian meridians, so it was the best experimental subject.

And over the years, these spirit monkeys have contributed a lot to Lin Chen's immortal cultivation experiments, if they were placed in their previous lives, Lin Chen would definitely award them a Nobel Prize for experimental materials.

As for what experiments, in addition to the previous ones, of course, they are now experiments to study the efficacy and side effects of soul nourishing incense.

After all, this kind of thing that has not been tested is directly used by it, Lin Chen is afraid that it is not the old birthday star who eats arsenic, and he will have a long life!

Lin Chen took the ten spirit monkeys who fell into a coma, walked out of the secret room, turned left and right in the passage, and finally came to a unique place.

It was surrounded by walls as white as new, and a series of formation prohibitions were inscribed on them. The upper part of the room adopted a secular trick to prevent trick detection, and the lower part of the trap and prohibition were built, which was enough to see the importance that Lin Chen attached to this laboratory.

On the floor and in the corners, there are flame talismans, and in the protruding walls on the side, a large amount of fire oil is buried.

If something is wrong, a single fire bomb can scorch the place, obscuring all traces.

The rooms in this place are one by one, and as long as there is an accident, they can be sealed down to prevent the expansion of the scope of influence.

It's not that Lin Chen thinks too much. However, the scientific experiments of the materialist world in the previous life all had various dangers such as poison gas leakage, virus infection, and biological mutation, not to mention that this life is still an extraordinary world.

Lin Chen didn't want to do the experiment, so he was killed by the test subject.

No matter how cautious you are, you can't overdo it!

When Lin Chen arrived with this batch of unconscious spirit monkeys, there was already another batch of experimental subjects in the laboratory.

That's also a group of spirit monkeys.

Unlike the monkeys brought by Lin Chen who fell into a coma due to damage to their souls, this group of spirit monkeys looked very healthy, and their eyes were even brighter.

Even though he was trapped in the iron cage, he jumped up and down from time to time, and kept gnawing with his teeth and fingers, and clasped the iron rod, trying to escape. What's more, he kept grimacing at Lin Chen, scratching with his teeth, as if he wanted to intimidate him.

Lin Chen didn't care about this, in his opinion, this is better, after all, healthy and standard experimental specimens can provide him with a more accurate judgment, isn't it?

The unconscious spirit monkey was placed, and then the innermost laboratory was directly opened.

It is surrounded by a glass wall made of special materials, with a two-meter laboratory table in the middle, and a fire charm for sterilization and disinfection on the transparent glass of the ceiling.

Lin Chen checked the experimental device three times, then put an unconscious spirit monkey on the experimental table, then took out an experimental log book and stood outside the laboratory.

"Soul Nourishing Incense 3.0 Corrected Version Test Experiment ......" Lin Chen's eyes froze, and he focused his attention, "Start now." ”

As soon as the words fell, his whole temperament changed suddenly.

If he used to be like a monk, chic and romantic, now the whole person's temperament has become indifferent and pure.

He snapped his fingers, and the soul-nourishing incense in the laboratory was immediately ignited, and a faint fragrance filled the room under a little spark.

Lin Chen stared closely at the spirit monkey on the experimental table, observing its movements at all times.

Lin Chen was just an ordinary college student in an ordinary university in his previous life, not a famous scientist, and he was a computer major, and he hadn't done many experiments, so he really didn't understand those high-level scientific experiment methods.

However, there were two methods, which he remembered very well.

One is to change only one of the factors at a time, and control the remaining factors unchanged, so as to study the influence of the changed factor on things, study them separately, and finally solve them comprehensively.

The other is to reveal the properties of things by comparing them based on their similarities and differences.

That is, the control variable method and the controlled experiment method learned in high school textbooks!

Judge whether the medicinal effect is sufficient by comparing the situation of the soul damaged spirit monkey after absorbing the soul nourishing incense!

Through the state of the healthy spirit monkey experiment, judge whether there are hidden dangers in the new version of the soul nourishing incense!

And the contrast between the two!

Although Lin Chen did not have the means to observe the soul, there are also methods in science to understand things without direct observation, such as indirect observation!

The ancients once said: "Spiritual feet do not think about sexual immorality, energy is sufficient and do not think about food, and spiritual feet do not think about sleep." This means that a person who is energetic will be physically lively and energetic.

In other words, the 'god' is also the soul, although it is elusive and observable, it will manifest itself in the body, and through this performance, Lin Chen can judge the medicinal effect of the soul nourishing incense!

Just like at this time. Lin Chen's eyes emitted a faint white light, and the unconscious spirit monkey on the experimental table was delicate in his eyes.

"Its eyelids, seem to move?" Lin Chen's eyes moved, and he glanced at the soul-nourishing incense burning in the room with his spare eyes, and half of it was gone.

'The spirit monkey on the experimental table was damaged by my spiritual power impact, and the first two versions of the soul nourishing incense had to be tested at least ten times before it had this effect, it seems that the medicinal effect has reached my needs? No, there may be a bias in one set of data, a few more experiments......'

Lin Chen groaned for a while, and after the incense was burned, he went in to observe it, and then changed to a spirit monkey and repeated the experiment many times.

'Preliminary judgment is that the medicinal effect of the soul-nourishing incense is sufficient. Next, the side effect experiment began...... 'Lin Chen put an ignorant and undamaged spirit monkey into the laboratory and lit the soul nourishing incense again.

Lin Chen's eyes widened, looking at the healthy spirit monkeys in the laboratory, wanting to know if the soul nourishing incense had side effects, and if so, what they were.

After all, the production of soul nourishing incense was changed from the prescription of the mortal world, and the probability of problems in this process was very high, if it weren't for Lin Chen's use of the elimination method to sift out most of the unlikely answers, plus the consumption of medicinal materials was far less than that of alchemy, otherwise, it really wouldn't be able to be made.

First of all, after a while, the originally lively and chaotic spirit monkey became a little depressed, and he felt a sense of drowsiness.

"Huh?"

Lin Chen was a little puzzled, this situation was not within the scope of his expectations.

Then, with a sudden click, the spirit monkey fell straight onto the experimental table.

Lin Chen couldn't help frowning, but he didn't rush in, he couldn't easily draw conclusions before a round of experiments was completed.

After the experiment was over, Lin Chen repeated the experiment a few more times, and the situation was still the same.

"It doesn't seem to be a special case, but why is this lethargy happening? Could it be that something went wrong with the product I was researching? Lin Chen frowned deeply, but quickly let go.

"Instead of such blind speculation, it is better to dissect and see." Thinking of this, Lin Chen picked up the scalpel without hesitation.

Although he can't dissect the soul for the time being, he can judge the situation based on the various changes in his body.

After all, in Lin Chen's opinion, all problems encountered in the experiment can be solved by dissection!

I don't know how long it took, Lin Chen washed away the blood stains on his hands.

"I see...... The medicinal effect of the new version of the soul nourishing incense is too strong for the spirit monkey, and there is a calming effect in addition to various elixirs, which are superimposed in the process of mixing, and finally produce an effect similar to hypnosis. ”

"However, this kind of hypnosis is not harmful to the body, but through sleep to make the body better absorbed, that is, ......"

For some reason, Lin Chen suddenly thought that this new version of Soul Nourishing Incense could not only be used to strengthen himself, but might also be used in battle.

As long as you wear a sachet made of this soul-nourishing incense during the battle, as long as the battle lasts long enough, the enemy will feel sleepy.

Distractions in battle can have devastating consequences, let alone falling asleep in front of your enemies.

And this sleeping effect is caused by tonics, such as detoxification pills and rejuvenation pills, not only can not be relieved, maybe it will be aggravated!

"Of course, the spirit monkey may have this effect, but it is not necessarily the same when it comes to the monk itself, but after this experiment, I at least understand that even if it has side effects, it will not be too ......."

Lin Chen stood in place, constantly thinking.

The study of this soul nourishing incense is not only to enhance his spiritual power, but also related to Lin Chen's breakthrough in the foundation building period and the study of [soul].

"After the first two editions of the research, I can be sure that there is a special aura in the soul nourishing incense, which can enhance the human soul ......"

"But the problem is that the soul, or divine soul, can only be observed and possessed during the foundation building period...... So if I want to study further now, I have to figure out the mystery of the foundation building period first? ”

Lin Chen hesitated, but still packed up everything in front of him, turned around and went to another laboratory.

The monkey's experiment had already proved that the side effects of the new version of the Soul Nourishing Incense would not be too great, and the next monk experiment was a long-term follow-up process, and it would not end in a while, so he decided to shift his focus to other places.

In the other laboratory, it is carved with a large number of runes, and there are also a lot of discarded spirit stones that have no spiritual energy.

He took two items out of the storage bag and placed them on the lab table.

They are the [Condensate Liquid] purchased from Yunlaifang City and the [Medium Grade Spirit Stone] purchased at a great price.

Lin Chen looked at the things in front of him, synthesized the information he had gathered, as well as the items related to the foundation building period in front of him, and slowly fell into deep thought.

"The Qi refining cultivator is [True Qi], but the one that the Foundation Building Period monk has is called [True Yuan], plus there is an essential difference between the monks of different realms, does this mean that the aura is the same as the particle, and there is an energy level?"
