Prehistoric: The understanding is against the heavens, deducing the mythical magic method

A total of seven gourds were formed on the innate gourd vine.

The first purple-gold gourd was taken away by Taiqing Lao Tzu, and Lao Tzu used it to hold the pill he refined, in Journey to the West, two alchemy boys stole this gourd to the lower realm and turned it into the Golden Horn King and the Silver Horn King, which made Sun Wukong suffer a lot of losses.

The second purple-green gourd was taken away by Yuan Shi Tianzun, and Yuan Shi Tianzun used it to conceive the magic weapon he refined, so this gourd is also called the pregnant treasure gourd.

The third purple-yellow gourd was taken away by the Tongtian Sect Master, and later the Tongtian Sect Master put two water and fire unicorns in it, so this gourd is also called the Water and Fire Gourd.

The fourth purple-white gourd was taken away by the Eastern Emperor Taiyi, and later the Eastern Emperor Taiyi practiced this gourd into a flying knife for cutting immortals and gave it to his nephew Lu Press, so this gourd is also called the Killing Immortal Gourd.

The fifth purple-blue gourd was taken away by Nuwa, who trained this gourd into a demon flag, which can attract all the goblins in the world, so this gourd is also called the demon gourd.

The sixth purple-red gourd was taken away by Hongyun, and Hongyun practiced this gourd into a ninety-nine soul-scattering red gourd, and later Hongyun fell into the hands of Zhen Yuanzi because of Hongmeng's purple qi.

As for the seventh purple-black gourd, before it was conceived, the innate gourd vine withered.

Now the Tongtian Sect Master gave Zhang Tianchen the purple and yellow gourd, but it did not contain a water and fire qilin.

Zhang Tianchen planned to use this gourd to hold his Boundless Sword, and the name was also chosen, so it was called the Boundless Gourd.

"After you go back, you will be able to cultivate well, if you don't understand something, you can come and ask me. The Tongtian Sect Master said.

As soon as these words came out, it showed that Zhang Tianchen's status in the sect had improved a lot, although he was still an outer disciple, he enjoyed the privilege of being a part of his own disciples.

"Thank you, teacher, disciple retires. "

Zhang Tianchen gave up his resignation and returned to his cabin.

In this big competition, Zhang Tianchen can be said to have gained a lot, not only has his status in the sect been greatly improved, but also received the inheritance of Lao Tzu's Dan Dao and the immeasurable gourd rewarded by the heavens.

Zhang Tianchen took out the immeasurable gourd and began to refine.

The immeasurable gourd is the best innate spirit treasure, with a total of forty-two prohibitions.

Refining the prohibition is actually the rune on the magic weapon.

The runes on the Boundless Sword were all carved by Zhang Tianchen himself, so he didn't need to refine them at all, and he could use them directly with his own Yuan Shen Mark, and he could also exert the maximum power of the Boundless Sword.

Three hundred years later.

Zhang Tianchen refined all the forty-two prohibitions of the immeasurable gourd.

Such a speed can be said to be very terrifying.

Even if it was Da Luo Jin Immortal to refine the immeasurable gourd, it would take at least tens of thousands of years.

Zhang Tianchen was refined in only three hundred years, mainly relying on his anti-heaven understanding.

After marking his own Yuan Shen mark on the immeasurable gourd, Zhang Tianchen loaded all his immeasurable swords into it.

"The number of Infinite Swords is still too small, and it will have to be refined in the future. "

There is no upper limit to the power of the Infinite Sword Array, the more Infinite Swords there are, the stronger the power of the Infinite Sword Array, and if you want to reach the power of the Mixed Yuan Formation, you need at least 129,600 Infinite Swords.

After refining the immeasurable gourd, Zhang Tianchen began to comprehend Lao Tzu's Dan Dao inheritance.

When he had just received Lao Tzu's Dan Dao inheritance, Zhang Tianchen had already realized that this alchemy technique would be of great help to his future cultivation.

Let's take a simple example.

The ordinary 10,000-year-old elixir is useful to the Heavenly Immortal Realm, but it has a very small effect on the True Immortal Realm, and it basically has no effect on the Xuan Immortal Realm.

But this alchemy technique can refine dozens of ordinary 10,000-year-old elixirs into a golden pill that can improve the cultivation of the Xuan Immortal Realm.

In the flood wilderness, the elixir of ten thousand years cannot be said to be everywhere, but it is not a rare thing.

If Zhang Tianchen was willing to spend some time searching, it would not be particularly difficult to find a 100,000-year elixir or a million-year elixir.

In the blink of an eye, a thousand years have passed.

Zhang Tianchen has thoroughly understood Lao Tzu's Dan Dao inheritance, and what is lacking now is actual operation.

Lao Tzu's Jindan is divided into one turn Jindan, three turns Jindan, six turns Jindan and nine turns Jindan.

The first turn of the golden pill is useful for the Xuan Immortal, the third turn of the golden pill is useful for the golden immortal, the sixth turn of the golden pill is useful for the Taiyi golden immortal, and the ninth turn of the golden pill is useful for the Daluo golden immortal.

"Come out and find some elixir and try this alchemy. "

Kunlun Mountain is a top-level cave blessed land, there are many elixirs in the mountain, elixirs less than 10,000 years old, and the disciples of the three sects generally look down on them.

No matter how many years Zhang Tianchen is, as long as he sees it, he will dig it up.

For those who are young, he plans to dig them back and plant them to cultivate a medicine field of his own.

After sweeping in the Kunlun Mountains for a thousand years, Zhang Tianchen found a lot of 10,000-year-old elixirs, and also found a few 100,000-year-old elixirs, but unfortunately, he didn't find a million-year-old elixir.

After returning to the cabin, Zhang Tianchen first planted the elixir below 10,000 years, and then took out some materials to refine a Danding.

If you want to do alchemy, Danding is indispensable.

However, the materials on Zhang Tianchen's body are very limited, and this Danding is just a low-grade Houtian Spirit Treasure with six prohibitions.

"For now, it should be enough, and when there are materials in the future, I will refine a better one. "

After Zhang Tianchen prepared everything, he began to alchemy.

With both hands, he pinched a magic trick and pointed at the fire mouth of the Danding, and a raging flame ignited in the Danding.

Immediately afterwards, Zhang Tianchen threw a 10,000-year-old elixir into the ding, and the elixir slowly melted under the calcination of the flame, and the impurities in it were burned to ashes, and finally only a golden liquid remained.

While controlling the golden liquid, Zhang Tianchen put other elixirs into the Ding for refinement.

It took seventy-seven and forty-nine years to refine all the essence of dozens of 10,000-year-old elixirs.

"Condensation!".

Zhang Tianchen's gestures kept changing, and he began to condense the Dan.

Ning Dan is a technical job, if it is not properly controlled, the pill will be destroyed.

And, Ning Dan is a slow process.

It took Zhang Tianchen ninety-nine eighty-one years to fuse the essence of dozens of 10,000-year-old elixirs into one and turn them into a mellow golden pill.

"It's finished!".

Zhang Tianchen saw that he had succeeded in his first alchemy, and a touch of joy appeared on his face.

However, this golden pill is a golden pill that Zhang Tianchen used to practice, and it is only effective for the Xuan Immortal and below realms.

Zhang Tianchen is in the early stage of the true immortal, and his cultivation is comparable to that of an ordinary golden immortal, and the golden pill is no longer useful to him.

Putting away this one-turn golden pill, Zhang Tianchen continued to start alchemy, this time he wanted to refine the three-turn golden pill.

The three-turn golden pill is generally made with one or several 100,000-year-old elixirs as the main medicine, and hundreds of 10,000-year-old elixirs are refined.

In terms of refining techniques, in addition to the increase in the number of elixirs and the higher age of elixirs, which makes refining and condensing pills more difficult, there is one more step in the three-turn golden pill, which is smelting.

After the three-turn golden pill is condensed, it needs to be smelted twice to make the medicinal properties more integrated.

These two smelting are the 'two turns' that are more than the three turns of the gold pill compared to the one turn of the gold pill.
