At the same time, Ling Xian was worried about how to become a Yuanying Cultivator.

Condensing the Yuan Infant is extremely difficult, after all, the Divine Cultivator is just a legend, the Yuan Infant Immortal Cultivator, in a sense, is already the top figure in this world, once the baby is successful, it will really become an admirable powerhouse.

But looking at the world, in the three thousand worlds, there are really not many monks who can come to this point.

Ling Xian is now in the late stage of Jindan, and his strength is not inferior to that of ordinary immortal cultivators in the early stage of Yuan Ying.

But the strength to be able to do this step is fundamentally different from whether you can get married by yourself.

If he hit the Yuan Infant Stage now, Ling Xian didn't have much certainty.

So what should you do next?

Ling Xian sorted out his thoughts.

Think about it.

Half a day later.

I already have a plan in mind.

The top priority is to continue to improve his mana, although he is already in the late stage of Jindan, but there is still a little gap between him and the Great Perfection, more or less.

And the closer the mana is to the Yuan Infant, the easier it will naturally be to break through.

This truth is simple and clear.

But having said that, how to improve mana is also quite confusing.

The simplest and easiest way to think of is nothing more than retreat and penance.

At another time, Ling Xian would do the same.

Cultivating immortals naturally means enduring hardships, and there will be no pie in the sky in everything.

But that's right.

The time left for Ling Xian now is only a handful.

His mood was very urgent, and he even had a feeling that danger was imminent, so no matter what, Ling Xian didn't have time and mood to meditate slowly.

Or rather, he wanted to keep it as short as possible.

Then the only option left is a panacea.

However, there were not many pills that could increase the mana of the Jindan monks. Ling Xian's purpose this time was to advance, not to refine the body, so the Five Elements Forging Body Pill was not very useful.

The rest of the pills, Ling Xian had already used them up.

Although their own dantian purple mansion. There is a demon holy relic that can transform the elixir.

But at this time, it was far away from water that could not quench the thirst, because Ling Xian didn't know what kind of pill he needed to transform into what he needed.

It would be nice if the book was not blank, but could be consulted.

For example, if you need to refine a certain precious elixir, you can find out which raw materials are needed in the Dan Book.

In that case, it will save a lot of trouble. What you want to do can also be targeted.

Ling Xian thought with some extravagance.

But will there be such a good thing in the world?

Wait, it looks like I haven't tried it before.

In the past, he always took a pill, and then handed it to the Heaven and Earth Danshu for his own analysis.

Come to think of it.

A hint of excitement flashed across Ling Xian's face.

Although he felt that such a good thing was a bit outrageous, Ling Xian still sank his mind into the Dantian Purple Mansion.

The foreground was blurred, and then it appeared in the mysterious cave.

What caught my eye was still the alchemy furnace, and there was a blank pill book suspended in mid-air.

Ling Xian's heart moved.

Concentrate your senses. However, the blank Danshu remained motionless.

A hint of gloom flashed across Ling Xian's face, but of course it was impossible to give up like this.

Regardless of whether it succeeds in the end or not. With his character, of course, he has to try hard.

Do your best and obey the destiny of heaven.

Not to mention, this attempt really had an effect, and after a few hours, it seemed as if a breeze was blowing, and the blank Dan book really opened by itself.

This process does require concentration of consciousness. But skill is also essential.

A hint of joy flashed across Ling Xian's face.

It's like a guess on your own, a solid step.

But then, what to do is quite a matter of thought.

Ling Xian thought for a moment. I decided to try it with the previous pill first.

His mind moved, and a small pill appeared.

Tonic elixir!

As the name suggests, it can replenish the spiritual power lost by immortal cultivators.

And this elixir is based on the Hui Qi Pill, and the treasure refined with this demon clan's holy relic, can it be done the opposite now?

Through the tonic elixir, what kind of materials or treasures are needed to refine it.

Ling Xian thought to himself and began to try.

As soon as his mind moved, the Replenishing Spirit Pill flew to the Heaven and Earth Pill Book by itself.

And yet there is no use, or nothing happens.

Because the Tonifying Pill is refined from the Heaven and Earth Pill Book, it is impossible to refine it twice, so no new formula can be derived from it.

Ling Xian had already known this in his heart, but he wouldn't be surprised by anything.

If you want to know what you can refine based on the Replenishing Pill, you need to take a real Replenishing Pill, but what Ling Xian wants to study now is not this.

He wanted to deduce in reverse what materials were needed to refine the Tonic Pill.

This needs to be tried, figured out, and deduced backwards, and it is unknown whether it will succeed.

However, once it is done, the harvest is staggering.

That's why Ling Xian worked hard, unwilling to let go of the slightest opportunity.

But I really don't have the slightest clue what to do.

Ling Xian could only try little by little.

However, this process is much more difficult than opening the Heaven and Earth Dan Book.

Ling Xian didn't sleep, and after three full days of experimentation, he still didn't gain anything.

I was going to give up.

For no other reason than because I have no indication that such an attempt will succeed!

But then, things took a turn for the better.

When Ling Xian once again brought the Replenishing Pill close to the Heaven and Earth Danshu, the blank Danshu flipped by itself, accompanied by a "bang-la-la" sound, and from the surface of the Danshu, a pillar of light as thick as an arm was scattered, just enveloping the Tonifying Pill.

Ling Xian's face was happy, and he saw that the pillar of light dissipated, and on the surface of the Dan Book, there was a spiritual glow circulating.

Red, orange, yellow, green, blue, purple......

Colorful change.

Then the book of Nadan was reopened.

A golden text came into view.

The tonifying elixir is a first-order mortal elixir, which can be replenished in small amounts, and the mana lost by the monks, if you want to refine this thing, you can use the Huiqi Pill as the basis, and use it as a group of ten to refine the secret technique of Dan alchemy, and you can refine the tonifying elixir.

Without the slightest error!

The reverse derivation has a result.

Ling Xian's face was full of ecstasy, but after being happy, he was full of doubts.

This attempt, it doesn't seem to be much different from the previous one, in all fairness, I don't have much hope, how can I succeed inexplicably?

This point must be clarified, otherwise, I still have not mastered the entire derivation process.

As soon as his mind moved, the pill went from the pill book to his hand.

On the surface, it is really no different from ordinary tonic elixirs.

Wait, the color of the pill here seems to be darker, red like blood.

Could it be ......

Ling Xian's mind moved, withdrew his divine sense, returned to the cave, and took out the spirit tonic pill here to observe carefully.
