Clenching his fists and feeling the vigorous power in his skeletal muscles, Yang Yu was satisfied to admire his body in front of the floor-to-ceiling mirror.

"Tsk."

"This is a good body."

If you look inside with your divine sense, you will find that Yang Yu's bones are crystal clear, and the muscles and veins are strong and powerful, if the muscles and veins of ordinary people are full of mud, sand and stones, and the ditches that are blocked and unbearable, Yang Yu's veins are like a gurgling stream, and the breath of the whole body is unimpeded.

Every time there is a breakthrough, the sea of qi in the body will double in size, if the sea of qi of an ordinary peak qi refining cultivator is a small pond, then the sea of qi at Yang Yu's dantian is Dongting Lake.

After putting on a thin veil with satisfaction, Yang Yu sat cross-legged and began to think about reviewing his past.

There are too many secrets on his body, and if it is possible, he would rather find a place to survive until he is invincible in the world.

However, there is a way to cultivate immortals, and to cultivate the wealth of the Dharma couple, although he has a tower to ascend, but every piece of knowledge must be learned slowly by himself.

Not to mention, you haven't learned mechanical knowledge, and you are given a precise drawing in front of you, do you understand?

A lot of precision machinery, need special materials, so that the strength and hardness, conductivity and other properties can be regarded as passable, you have no knowledge of materials, just use ordinary metal to make parts, can you use?

There are also genetics, mathematics, hundreds of subjects, all of which have to be studied!

A vast sea of books, documents, drawings.

Thinking of this, Yang Yu was both excited and worried.

Ay!

There is no end to learning the sea, and you can work hard to make a boat!

If only I had a system where you could check in every day and then be rewarded.

All kinds of Dan Array Talisman knowledge are rewarded every day!

A few days of rewards is what an alchemy master!

Moreover, from time to time, a 999 crit will be rewarded with a magic cheat, or a peerless magic weapon!

Even cultivation is a reward for decades and decades!

Now I only know how to make some primary talismans and seals, and I only know a little bit of skin when I cultivate immortals.

Even the ancestral exercises in the family felt more and more unworthy of their own immaculate spirit body.

Yes, the Innocent Spirit Body, this is an example of Yang Yu searching through the sect's literature but not finding a similar example, so he gave his own physique a name.

Hum!

"Let me practice such a garbage exercise, it's like a good piece of mutton, but it falls in a dog's mouth!"

After secretly slandering in his heart, Yang Yu continued to think.

I have tried many times but I can't succeed, presumably this foundation building period is not something that can be done by simply accumulating spiritual power.

Yang Yu guessed that this Zhuji Dan was not only full of spiritual power, but could also help Qi refining cultivators break through the realm.

Otherwise, Yang Yu had already tried to drink the 100% concentrated spiritual liquid as water, so that there was no sign of liquefaction except for the growth of the qi sea in his body.

Yang Yu deduced from this that it must have been during the refining process of Zhuji Dan that a special compound or a special enzyme was produced, so that after the monk took it, the effect of a catalyst would be produced accordingly, thus transforming the sea of qi in the dantian into the liquid state of the Zhuji monk.

Then, his next plan is to mix in the sect to build the foundation Dan, and after successfully building the foundation, he will fish in the sect, which can be regarded as returning to the cultivation of the sect.

After that, try to find a way to get to Dajin safely before the Demon Dao invades, or use the ancient teleportation array of that mine to run to the Chaotic Star Sea.

After all, the Tiannan region is poor in resources, and it won't be long before the two realms of righteousness and demons will wantonly swallow up those neutral forces, and then the two realms will start a long-term showdown.

I just want to quietly engage in scientific research and do academics!

After setting the following route, Yang Yu probed his divine sense into his dozen storage bags and counted his weapons and equipment.

There were several generators, a number of electric wires, hundreds of barrels of fuel, and a lot of large-caliber guns and ammunition piled up on the side.

In addition, he also used machine tools to make parts, and then the car came out of an airplane.

Yes, you heard it right.

A replica of the World War II P51-Mustang fighter-bomber, with a 37mm cannon on each wing.

It's not that Yang Yu doesn't want to get a jet out, it's just that Yang Yu doesn't know a lot of relevant knowledge now, and Yang Yu can't make a lot of special materials needed for key parts.

However, it is enough.

The belly of this replica is engraved with a floating rune, which can counteract the gravity of the fuselage and levitate in the air when it is powered up.

The various flying magic weapons and floating formations in the Immortal Cultivation Realm used this kind of rune and its various derivative transformations.

On the wings of the fuselage, Yang Yu installed propellers to provide power for movement.

As a result, the aircraft can not only levitate in the air stationary like a helicopter, but also maneuver at high speed like a fighter.

Although it is not yet supersonic, it is enough, and it can fly nearly 700 kilometers in an hour.

With this plane, the world is so big, Yang Yu actually goes to most of them.

However, Yang Yu rarely used it, and only secretly drove a few laps in a place where no one was around.

The reason is very simple, this is the Immortal Cultivation Realm, and the divine consciousness coverage of those old monsters is hundreds of thousands of miles at every turn, and it is fast and fast.

Yang Yu didn't want to drive the plane around in mid-air, when suddenly a disgusting old face appeared outside the cab, and he said to himself with a smile:

"Little friend, the bird-shaped magic weapon you opened is so chic! Let's talk, okay? ”

Well, just thinking about it gives me goosebumps.

It's still "good", the reputation is not eye-catching, and it's safe!

If a knife is slashed, how can you engage in scientific research?

However, now that he has reached the peak of Qi refining, it is time to do it.

Six years ago, when I first left the strict management of the clan and was recommended to join the sect, I felt like I had entered heaven.

For comparison, ethnology is more like a boarding middle and high school, with strict management, and the children live in collective dormitories, concentrating on practicing and practicing spells every day.

In this case, how could Yang Yu disappear and then run to the Seven Xuanmen thousands of miles away to grab the treasure?

The sect is different, it is very similar to the university.

The outer disciples are free to go to various peaks such as the Dan Weapon Array to practice skills, or they can go to the Spell Mountain Peak to listen to the senior brothers teach the release skills of various spells, and they can also go to the mission hall to do sect tasks.

Yang Yu took this opportunity to take a month off, preparing to fight all the way to the Seven Xuanmen to seize the treasure.

Who knows, I didn't expect to fall for the gangster's trick halfway!

After waking up in a daze, Yang Yu found himself lying naked in the wilderness, with several vultures squatting next to him, as if waiting for his breath!

After seeing that he was "resurrected from the dead", the vulture, which had been waiting for a long time, flew away disappointed.

Yang Yu was frightened into a cold sweat for a moment, and felt that the family protection rune on his chest was faintly hot, and then he was glad that he had picked up a life.

This rune is a secret method used by the family to tattoo the important juniors in the family, when the juniors encounter a life and death crisis, it can inspire a phantom reserved by the ancestor to advise the opponent not to do it!

If the other party insists on killing the killer, this rune will also turn into a curse and stick to all the killers after the host's death.

The family will definitely chase the murderer with all their might!

And the murderer will be punished with extreme brutality!

After all, Spirit Beast Mountain was once one of the six realms of the Tiannan Demon Gate, a branch of the Imperial Spirit Sect.

Although the behavior has been reined in after independence, it is still deeply rooted!

Although all the things in his body were lost, fortunately, Yuanyang was not lost, and his butt did not hurt.

It's okay, it's okay.

After this incident, Yang Yu realized that he was almost lost in his mind by the desire to seize the Palm Heaven Bottle!

In this immortal cultivation world, except for the major sects, major families, and the fang markets everywhere that have patrols and law enforcement teams, a large area is actually a lawless dark place!

In these places, there are no law enforcement halls, and there are no rules against fighting.

There is only one rule: take what you want!

After receiving this lesson, Yang Yu deeply realized: Gou Dao is the secret of longevity!
