Behind the Tibetan Dharma Building, in the stables.

Mo Chengjun circled the four-eared donkey demon back and forth many times, looking up and down for a long time, but he didn't find any external injuries.

Then, as if thinking of something, he leaned down and looked somewhere.

At this moment, the silent donkey demon couldn't hold back any longer, he twisted his buttocks, and kicked out his hind legs directly, splashing a little bit of dirt.

At the same time, he kept scolding angrily: "Grass, where are you looking?" Where to look?

If you want to die, you don't, if you want to die, say it, Lao Tzu will fulfill you. ”

Mo Chengjun was also guarding against him, and he turned around and dodged over.

He ignored the donkey demon's abuse, but asked with interest, "Can you actually come back?" And it's all back with all the beards and tails, which is incredible!

I thought that your best situation would also be to become a eunuch donkey, uh, donkey eunuch? ”

When the four-eared demon donkey heard this, his whole body trembled, and he seemed to think of something terrifying.

However, he still said strongly: "You are the eunuch, and your whole family is a eunuch." ”

Mo Chengjun's face changed, and he slapped the donkey's ass viciously: "You, talk well, otherwise, hey, hey, hey, hey......"

As he spoke, his gaze swept over the vital parts of the donkey demon again, and the threat was overflowing.

The donkey demon's face was stretched longer, but he was still very arrogant and said the most cowardly: "Hmph, I'm too lazy to pay attention to you." ”

As he spoke, he ignored Mo Chengjun and walked back to the stable by himself.

But Mo Chengjun was even more curious, and while filling some forage for the donkey demon, he asked: "Frankly speaking, if the fairy asks her teacher, when the Four Seasons Sword Venerable captures you back, it will definitely be a big dismantling."

I'm pretty sure of that.

Moreover, if it weren't for the breakthrough from the fairy retreat, you would have died a long time ago.

So, this time, it's amazing that you were able to get out of it with your whole body.

Come on, come on, tell me, tell me, how the hell did you do that?

Or, what did you say to Ruoli Fairy to let her let you go? ”

The four-eared donkey demon originally didn't want to pay attention to it, but looking at Mo Chengjun's stubborn fighting, he rolled his eyes and suddenly asked, "You, very curious?" ”

"Uh-huh!"

"Then I'll tell you, in fact, it's nothing, it's just that Ruoli Fairy asked some questions, and I, honestly, answered."

"That's it?"

"That's it!"

"You're fooling me, what exactly did you say?"

This time, the donkey demon tilted his head, squinted at Mo Chengjun, and smiled strangely at the corner of his mouth: "I can tell you, but are you really sure you want to know?" ”

“……”

"If you don't speak, you're thinking, since that's the case, I'll tell you, if you leave the fairy, you're asking me ......"

"Ahem, wait!"

Mo Chengjun suddenly shouted, interrupting the donkey demon's narration, and shook his head like a rattle: "Forget it, I still don't know, curiosity kills the cat, forget it!" ”

As he spoke, Mo Chengjun turned around and ran, he really didn't want to listen.

Here, watching Mo Chengjun run away, the four-eared donkey demon said with some disdain: "I'm a coward!" ”

It's just that when he turned his head, his donkey's face was full of bitterness: "Special code, special code, Lao Tzu was pitted, Lao Tzu was pitted!"

Dog's day, I'll grass your uncle! ”

Until this time, the four-eared donkey demon seemed to finally realize that the chase outside the Sifang City was calculated by some existence.

……

Sometimes, the more you know, the more you know, the more dangerous it is.

Traditionally, those who have been silenced are those who know too many secrets.

Since the donkey demon was sent back, it actually meant that his so-called secret was not very important, but Mo Chengjun still gave up asking.

Because, he is very clear about his positioning, he is not a fighting immortal cultivator, there is no need to go to fight with others every day to grab resources.

He is not a farming-type immortal cultivator, and he doesn't have an immortal mansion space in his hand, so naturally he can't eat the dividends of farming.

He is a scientific research monk, and he takes the path of cultivating immortals through science and technology.

Therefore, just focus on yourself, and ignore other things if you can ignore them.

After this incident, no one really bothered him, and he also devoted himself to cultivation and scientific research.

This time, he had to figure out what this 'qi' was.

So, Mo Chengjun launched a general attack on this topic, and the goal he set for himself was to vow not to give up until he reached his goal.

Another whole month passed, and he made no less than ten hypotheses, but each time he didn't last more than two days before he falsified it.

For a month, he didn't make an inch, and almost blew his hair.

But you have to say that there was no result at all in this month.

That's not either, because, on a whim, he had a new idea.

The biggest problem now is that I don't know what 'qi' is, so I try to see 'qi'.

Since the 'qi' in the body cannot be observed, then observe the 'qi' outside the body.

And when it comes to the outside of the body, what is the 'qi' that can last for a period of time?

As the name suggests, mana!

Yes, it is mana, because mana is equal to the heaven and earth spiritual machine attached to the spirit, god and ...... Gas!

But how can mana be observed?

Others can't, but Mo Chengjun can, he just looks at it with the naked eye.

However, the individual mana is too small, small to resemble floating dust, to be observed in depth.

But in fact, dust can also be observed, with the help of tools.

At this point, a logical chain was bridged.

This time, Mo Chengjun finally found another way, and he couldn't talk about it, but it was better to have a direction than no direction.

Well, it's a bit of a mess!

But to sum up, it is not difficult to understand, since 'qi' is not easy to detect, then it is good to observe the thing that carries it, that is, mana.

And the mana is too weak, even if his eyes can directly look at the heaven and earth, it is impossible to see the inner structure of the mana.

Therefore, you have to find a way to see more clearly, more carefully, and see the inside.

And for this, Mo Chengjun has two directions to solve.

The first is to use the traditional method – since the eye can't see, find a way to make the eye see.

That's it, the Dharma's Eye!

Dharma Eye, also known as Pupil Technique, Heavenly Eye, Wisdom Eye, Divine Eye, etc., according to different methods, the sayings of the major immortal sects are also very different.

Its functions are also different, some are mainly used for observation, which is an enhanced version of binocular vision, and some directly use it as a means of attack.

For example, there is a sect in Yunzhou, called Chiyanmen, which specializes in the fire system of eating qi and fighting the fire method.

And they have a secret technique called the Red Flame Eye.

Cultivation can send out the red eyes and divine light, and it has the effect of fixing the soul and destroying the soul.

If you want to say how strong this red eye divine light is, it's actually not counted, but when the fighting method is fierce, he suddenly gives you this move, and it will be very fatal.

Of course, most of the Dharma Eyes are mostly used to see things, for example, the commonly used Spiritual Eyes can be used to see the flow of heaven and earth qi.

For example, the ghost eye can see the ghost ghost.

Another example is the demon search eye, which can be seen with demonic energy, which is a must for finding demons and killing demons.

Otherwise, with the ability of demon transformation, hiding in the sea of people, how can you find it?

What Mo Chengjun wants to do now is actually to find a magic eye that can observe the subtleties and observe the invisible to the naked eye, naturally, this has to be found in the huge collection of books in the Tibetan Law Building.

And with this in-depth study and study, Mo Chengjun found that the water of this 'magic eye' was too deep.

Most of these ordinary magic eyes are like Lingguan magic eyes, they are used when they are used, and they are stopped when they are not in use, and they are more commonly spread, at least in this huge Galaxy Sword Sect, these spells are not difficult to find.

But if you want to find those more powerful pupil techniques, I'm sorry, these are all secret methods of the major immortal sects, and they are not at all something that ordinary disciples can teach.

Even if it is a true transmission, it depends on the qualifications, the method cultivated, and then whether there is enough merit.

In short, in a word, the major immortal gates are all tightly covered with these, you want to peep, no way!

Secondly, follow the few introductory materials, or the few words that appear in some travelogues.

These Dharma eyes are looking up at the heavens and the earth and the nine shadows downward, or they are peeking through fate and cutting off cause and effect; Or perceiving into space, peeking into nothingness.

Well, it's all about how awesome it is, not to mention whether there is such an awesome effect, just one point makes Mo Chengjun helpless.

These Dharma Eyes are not a monk who can't reach the foundation, what can be tried, they are all Jindan, Yuanying, or the housekeeping methods of the immortal powerhouse.

As far as Mo Chengjun is concerned, he can't do it slowly, and even if he does, he can't use it.

After some searching, Mo Chengjun was speechless.

Well, this road may be possible, but it is also a dead end for him at this time.

But Mo Chengjun was not disappointed, because, this road is not passable, so it would be good for him to open another road.

Since you can't find a suitable one, let's build a microscope!

When he had this idea, Mo Chengjun felt that he had come to this world to live stupidly, and he had never thought about this kind of commonly used tool for research.

The so-called microscope, to put it bluntly, is a combination of two sets of lenses, and then fixed to both ends of the microscope.

Among them, the role of each group of lenses is equivalent to a convex lens, the one close to the eye is called the eyepiece, and the one close to the object being observed is called the objective lens.

The specific principle is that the light of the observed object becomes an enlarged real image after passing through the objective lens, and the real image is magnified again after passing through the eyepiece.

After two magnifications, we can see some small objects that are invisible to the naked eye.

The theory is simple, but it's not easy to actually do it.

Regarding the curvature, transparency, focal length, fine-tuning method of the convex lens, etc., it needs to be experimented with little by little.

The only thing that makes Mo Chengjun happy may be that this world already has glass, and it is transparent and bright enough.

Otherwise, if he were to study material manufacturing again, he would be crazy.

In order to better conduct experimental research, Mo Chengjun went to Yunjian City to find a handicraft shop, and tossed back and forth for nearly two months according to the graphics drawn in his memory, before finally having a microscope that could be fine-tuned.

And after the personal mana is separated from the body, it will quickly dissipate, and as a last resort, he found an almost discarded magic weapon to instill and preserve the mana, although it will also dissipate, but the speed is much slower.

Finally, he placed the instrument under a microscope.
