At the end of the Eastern Han Dynasty, Taoism was founded, and Taoism pursued cultivation to become immortals and live forever. Pen, fun, pavilion www. biquge。 info This is in line with the purpose of alchemy, and the union of the two sides becomes inevitable. Subsequently, most of those engaged in alchemy were Taoist priests, and Taoist alchemy basically became Taoist alchemy.

During the Wei, Jin, Southern and Northern Dynasties, the footprints of Taoist priests have spread all over the famous mountains, mainly engaged in alchemy activities. Among them, great alchemists and great medical scientists like Ge Hong and Tao Hongjing appeared. They not only devoted themselves to the practice of alchemy, but also wrote books and lectures, summarized and explained them theoretically, and laid the foundation for the further development of alchemy in later generations. What they did marked the maturity of alchemy in both theory and practice.

Alchemy aims at the pursuit of immortality, and it also has its own theories. This theory is first and foremost based on the belief that immortality can be sought and immortals can be achieved. An emperor like Emperor Wu of the Han Dynasty, who was eloquent and intelligent, thought that he was an autopsy after Li Shaojun died of illness, and regretted it, which shows how deep-rooted this belief is. On the basis of such beliefs, alchemists constructed their own theories. They believe that everything in nature is changing, and people's birth, aging, sickness and death are also changes. Some changes in nature can be brought about by humans, such as the smelting of dansha. For the human body, a similar method can also be used to make it immortal with the help of the power of external objects, which is to take Jindan. Ge Hong has a specific argument for it, he said: "Fu Jindan is a thing, and the longer it is burned, the more wonderful the change will be." Gold into the fire, refining will not disappear, buried in the sky immortal. Taking these two things can refine the human body, so it can make people immortal. This cover is pretended to be strengthened by external objects, and is like a fire that is nourished by fat, and cannot be extinguished. Copper green coated feet, into the water does not rot, this is to borrow the strength of copper to cut its flesh. Jin Dan entered the body, and he was in contact with Rongwei, not only in addition to the bronze and green. ("Hug Puzi Jindan")

That is to say, the elixir and gold are all refined, and the more they change, the more wonderful they become. When people eat them and absorb their essence, they have their characteristics and will be immortal like them. This is called "pretending to be external in order to strengthen oneself." This passage can be said to be the basic idea of alchemy, although it does not work in practice, but it has been believed by alchemists for many years. -----------introduction

"You have to succeed, if you don't succeed, you die!"

The wind tried his best to control it, and he saw that the four hundred and eighty-six sword weapons were all suspended around, and some of the key "sword weapons" of the Tiangang Thirty-six Sword Formation were controlled by the wind intent, and the others were gradually leading, and for a while, the four hundred and eighty-six sword weapons were all like water waves.

Although it was difficult, a white light appeared on all four hundred and eighty-six sword weapons.

"It's done!"

Although the wind still has to defend against those poisonous insects at the moment, and is often bitten by poisonous insects, at the same time, he also has to avoid the black-haired zombie chasing behind him.

But the wind is extremely excited!

With his achievements in formation, he simply cast a large-scale Tiangang Thirty-six Sword Formation that broke through the upper limit.

"Kill!"

The wind stared frantically at Jia Hypocrisy on the boat in the distance.

Condensed to the extreme in front of him, and an incomparably sharp wisp of sword instantly obeyed the will of the wind, like a meteor, crossing the sky, directly attacking Najia hypocrisy with an irresistible momentum.

"Die!"

Jia Hypocrisy on the boat was also shaking the blood-red cloth banner in his hand.

The cloth banner shook. The surrounding world was darkened, and I saw a number of fierce ghosts visible to the naked eye roaring out, these ghosts were a large number of powerful ghosts who fought with each other and devoured the remaining strong people, and after the cultivation of the magic weapon cloth flag, it became stronger and stronger.

And that's just a half-finished product, if it's true

is completely refined, and that's really terrifying.

But even so, with this half-finished magic weapon, Jia's hypocrisy is enough to be proud of the vast majority of demon-level figures.

"Roar~~" "Kill!" "Eat you!"

Countless ghosts are extremely hideous, and they let out a piercing cry, and after being nurtured by the cloth flag, these ghosts can already make sounds!

They are staggered with each other and all fly towards the wind at great speed.

Of course, compared with the Tiangang Thirty-six Sword Array of the Wind and the wind, it is still faster than the Tiangang Thirty-six Sword Array.

"Snort."

Jia hypocrisy held the dust in his hand, and the dust turned into three thousand white silk and blocked it crazily, but this wisp of sword was much more powerful than before, and it was hard to penetrate the layers of blocking, and Jia hypocrisy hurriedly even used the handle of the blood-red cloth banner that he grabbed with one hand to directly block that wisp of sword.

The sword was too fast, and Jia Hypocrisy barely touched the sword.

Snort~~ The sword slammed into the handle of the stick, and the entire blood-red cloth banner was slightly shocked, and the power of the sword suddenly became weaker, and then when it touched the black robe that the magic weapon armor on Jia Hypocrite's body turned into, barely left a black spot on the black robe and disappeared.

"Fortunately, it almost pierced my body and killed me."

Jia Hypocrisy was also frightened, the demon-level fight was the line of life and death, and he lost his life if he accidentally fell into the other party's move, "Hmph, now that he is bitten by a powerful ghost, he can't be distracted at all anymore, and he will definitely die if he is bitten by many powerful ghosts." "Jia is hypocritical and confident, even if he is bitten by these powerful ghosts, he will die.

…… The wind couldn't help but change his face when he saw the dense and large number of powerful ghosts whistling and flying, these powerful ghosts screamed and easily penetrated the six-layer fire Jiao out of the water, the powerful ghosts were originally ghosts, like weapons, fire Jiao out of the water, etc., they couldn't be stopped at all.

"Ate you." "Eat."

Countless powerful ghosts surged in an instant, drowning the wind at once, and all of them rushed madly into the wind's body.

"It's dead."

Jia Hypocrisy in the distance was even more confident waiting for the moment when the wind fell, but immediately after him, his complexion changed, because the blood-red cloth banner in his hand began to tremble, and the breath of the cloth banner was also constantly weakening, obviously the power was constantly decaying, "What's the matter?" How, how could this be? Jia Hypocrisy was furious.

This banner is his killer weapon, invincible!

But now the continuous weakening of the cloth banner aura means that the power of this magic weapon is declining, and the foundation of this magic weapon is those powerful ghosts............
