After a long time, Cang Tianqi, who was squatting on the ground, stood up.

At this time, he looked even more tired than before.

His gaze finally fell on the infant spirit embryo that he threw out.

With a move, the infant spirit embryo was caught in his hand.

"Alas!"

Cang Tianqi sighed, and couldn't help but shake his head, looking indescribably lonely.

There is a reason why he will suddenly change his mood.

And the reason for this is, of course, the infant spirit embryo in his hand.

The artifact infant he wanted to refine was completely different from the artifact pill he was using now, and it was precisely because of this that the refining method and the materials required were all different, even if it was the forging of the spirit embryo, it was completely different.

There will be such a big change, in the final analysis, it is all the difference between Jindan and Yuanying.

Jindan has no life, it is a dead thing.

But the Yuan Infant is different, the Yuan Infant is a living creature. Even if the consciousness of the Yuan Infant originated from the monk himself, it could not change the fact that the Yuan Infant was a living thing.

In the same way, when Cangtian abandoned the refining pill, he didn't consider that the refined pill needed to be a living thing, because the golden pill was originally a dead thing.

But refining the instrument baby, the sky has to consider this, because the yuan infant is a living thing.

In this regard, when Cangtian abandoned the forging of the infant spirit embryo, he specially selected the materials, the purpose of which was to have a certain vitality after the infant spirit embryo was refined, rather than a lifeless dead thing, so that once the spirit embryo was refined, his consciousness was injected into it, and he could control it as freely as a normal yuan baby.

Cang Tianqi didn't have the luxury of expecting how powerful the forged spirit embryo must be, he knew that with his current refining level, he might not be able to do this, so he had reduced the requirements to a minimum, as long as he had a certain amount of vitality.

However, the Infant Spirit Embryo he obtained this time did not have the slightest vitality at all, and it was completely a cold spirit embryo that was no different from other magic spirit embryos.

This kind of spirit embryo does not meet his requirements at all, and it can't even meet the minimum requirements, even if this infant spirit embryo is forcibly refined, nine times out of ten it is a failure, even if it does not fail, what you get in the end is definitely not the ideal instrument baby in the sky.

In the end, he got a useless scrap, so Cangtian abandoned his mood changed greatly in an instant, and the hard-worked forged infant spirit embryo fell to the ground.

At this time, he picked up the infant spirit embryo, and a sigh came out of his mouth, indicating that his emotions had stabilized, and at the same time, it also showed the helplessness and powerlessness in his heart.

"What the hell is the problem, all the materials of the forging infant spirit embryo have been carefully screened by me, although it is the existing material in my hand, there are certain restrictions, but the forged spirit embryo should not be lifeless at all. ”

Cang Tianqi frowned, he couldn't take a break at this time, and the forging of the infant spirit embryo failed, so he didn't have the heart to rest at all.

He searched for a reason......

Suddenly, his gaze fell on the spiritual liquid inside the jade bucket, and his expression suddenly changed slightly.

"There is no problem with the material, is it ...... The problem is with the spiritual fluid!" A flash of lightning flashed in Cang Tianqi's mind, and the speculation that suddenly popped up made him feel that it was most likely the real reason.

In order to confirm whether his guess was correct, Cang Tianqi immediately checked the spiritual liquid in the jade barrel, and then made various analyses based on this failure and the selection of materials.

An hour later, the spiritual liquid inside the jade bucket had all dissipated due to the lack of a prohibition, and no more spiritual energy was emitted, but this cave was filled with a large amount of spiritual energy.

At this time, Cangtian Qi also stopped checking the spiritual liquid in the jade barrel.

"The spiritual fluid used for cooling is not suitable, and some materials have to be replaced. ”

As he spoke, Cang Tianqi took out the pen, ink, paper, and inkstone again, and re-selected the materials based on the experience summed up by the failures again and again.

This time, he didn't choose according to the materials he had at hand as before, but what materials he needed, what materials were most suitable for refining the ideal beast baby, then he chose what materials, even if he didn't have this kind of material in his hands for the time being.

After a few moments, when he stopped writing, a new list of materials had been released.

"In addition to the existing materials in their hands, there are still three important materials, although these materials are precious, they should be available in the Yiqi Business Alliance, with their ability, there are very few existences that make them helpless, just to see if the buyer can afford the price. ”

In the Western Regions, there are quite a few branches of the One Qi Business Alliance, except for the Heavenly Machine Pavilion Wuyu City, almost all other high-grade spheres of influence have branches of the One Qi Business Alliance.

Therefore, for these three important materials, Cangtian Qi is not very worried so far, because there is at least a high probability that these materials can be purchased in the Yiqi Business Alliance.

At the moment, what he was most worried about was the spiritual liquid that cooled the spirit embryo.

The spiritual liquid he used to cool the spirit embryo was not bad, on the contrary, it was very special and precious, but this spiritual liquid was not suitable for forging the infant spirit embryo, so Cang Tianqi had to give up this spiritual liquid and choose other suitable spiritual liquid.

It's just that at the moment, although Cang Tianqi has re-selected the materials for forging the spirit embryo, he has not yet chosen what kind of cooling spirit liquid is more suitable for the infant spirit embryo.

"What kind of spiritual liquid is better to choose......" Cang Tianqi frowned, a thoughtful expression.

At this time, he recalled all kinds of classics about refining weapons that he had read, hoping to find a spiritual liquid suitable for the cooling of the infant spirit embryo from the refining knowledge he had learned.

Time passed little by little, and Cang Tianqi kept a thoughtful expression, constantly recalling and sifting.

I don't know how long it took, Cang Tianqi's eyes suddenly lit up, as if he thought of something!

"Perhaps...... It's a good choice!"

There was a hint of joy in his voice, and Cang Tianqi immediately closed his eyes, and his divine sense entered the storage bag, looking for something.

It didn't take more than a cup of tea, and Cang Tianqi opened his eyes.

"Found it!"

When the voice sounded, a flash of inspiration flashed in Cang Tianqi's hand, and a thick book appeared, and then, I saw Cang Tianqi not saying a word, and quickly flipped through it.

In fact, this classic has long been memorized, and the reason why he still wants to take out the classic book is just to confirm it again, because the matter of the infant is too important to him, and he will never allow any mistakes, even if it is a classic that he has memorized, he still chooses to take it out and reconfirm.

Because he had already memorized this classic, Cang Tianqi flipped through it very quickly, and in just a few breaths, his fingers stopped turning and stopped on a page.

On this page of the book, a towering tree is depicted, and below the portrait, there are dense small characters describing the tree.

There is a magical tree in the Western Regions, called the Tree of Life, which can move on its own and move uncertainly, which is extremely magical.

This tree is full of treasures, and its fruit can prolong life and increase the life of monks, and refine it into elixir, which has a better effect. Its branches and leaves are excellent materials for refining, and can also be used for alchemy and medicine.

It is said that in the trunk of the tree of life into a water bladder, the value of this liquid inside is the highest, this liquid contains a powerful vitality, is the holy product of physical healing, whether it is a monk or a demon beast and a spirit, all have miraculous effects, and this liquid can also be used for alchemy refiners, extremely versatile.

This liquid is called the fountain of life.

Seeing this, Cang Tianqi closed the book in his hand!

"Fountain of Life...... That's right, that's what I'm looking for. Since you are looking for the right material for the forging infant spirit embryo, this Fountain of Life is definitely an excellent choice!"

"It's just...... The whereabouts of the Tree of Life have always been a mystery, how can I find it?"

Cang Tianqi frowned again, pondered for a moment, and a determined look appeared on his face, as if he had made some kind of decision.

"I've been stuck at the peak of the late stage of the Jiedan for a long time, and it has taken decades to refine the Instrument Infant to no avail, so many years have passed, I'm not afraid of spending some more years, if I can't find this Tree of Life and obtain the Fountain of Life within five years, then I'll look for a replacement. ”

"If so...... If I am fortunate enough to find this fountain of life, and the record of the fountain of life in the classics is correct, then I am at least ninety percent sure that I will forge the ideal infant spirit embryo!"
