After staying in the quiet room with the good herbs in front of him, Li Mu entered the spiritual sea.

I want to have a good time.

Try synthesis first.

A piece of black bone branch and a piece of Qingfengcao were thrown into the pagoda.

"synthesis."

"Some materials cannot be synthesized."

Li Mu frowned and threw in another Spiritual Yuan Fruit.

"The number of combinations is too high and it cannot be combined."

It's really weird. It seems that there are only two kinds.

Li Mu thought about it for a moment, then took it all out, and threw away the gold and a colorful stone he had found before.

Finally, the reminder he wanted to hear sounded, "Please select the materials left behind for synthesis."

"Colorful stones."

Li Mu simply gave the order without thinking.

A golden light flashed, the tower value decreased by two points, and a light yellow stone fell.

What is this, colorful ore?

Li Mu strangely picked up the stone, ran the technique, and began to absorb spiritual power.

As time went by, his expression became more and more ugly.

Snapped!

Let him throw the stone aside.

He almost understood the meaning of synthesis, but it cost him a top-notch multicolored stone.

Synthesis is to combine the properties of one material with other materials to produce a new material.

The original multicolored stone, combined with the properties of gold, can no longer filter the spiritual power in the air, but becomes a stone without spiritual power.

Gold is not gold, and multicolored stones are not like multicolored stones. They are simply useless.

"What a big mistake." Li Mu seemed to understand, "We should keep the gold and combine the properties of the colorful stones into the gold."

He did as he was told, but now there was no gold, only the mirror.

Li Mu threw the mirror and colorful stones into the spiritual pagoda and chose to combine them again.

I won't make any mistakes this time, "Keep the mirror."

The mirror fell out, and there was a slight smile on his face. Li Mu put the mirror in his hand, feeling the spiritual power nearby, and a smile bloomed on his face.

Sure enough, the mirror absorbed the properties of the colorful stones and became one that can filter spiritual power.

After repeated operations, Li Mu immediately thought that he should buy more ordinary things and then synthesize top-grade multicolored stones, so that he could practice outside without worrying about others discovering his privacy.

If it is a transparent glove, the effect will be even better, but the Mythical Spirit Tower should only be able to synthesize minerals, just like the previous herbs, unchanged.

But that doesn't matter.

Use the synthesis ability in refining treasures? Just thinking about it, Li Mu will feel very happy, as if he combined cryolite into extremely hard spiritual iron, and an ice crystal spiritual iron will be produced immediately. If some high-end materials are combined

, combine two rare tenth-level materials? Then you can get materials that any treasure refiner can only dream of.

Can it be like this? Maybe high-end materials cannot be so easy. But they can be determined and synthesized, which is very suitable for refining treasures.

After testing, Li Mu temporarily settled on this idea and put his thoughts on fusion.

But pills are something that needs to be studied very much now.

Without thinking too much, Li Mu casually stuffed some herbs into the tower. It was expected that there would be many kinds.

"It is calculated that there are 7 first-class materials that require a tower value. I don't know the result. Are you sure you need to fuse them?"

"Fusion."

The tower opening opened, and a dark object fell down.

Li Mu hurriedly took it in his hand, and an unusual smell rushed into his nose, making him cry!

The reminder from the pagoda came, "The materials are not suitable and have been combined into useless materials. Please change the materials."

Li Mu had long thought about such a result, but when it actually came, he was extremely disappointed.

"Isn't it right that if you throw in some medicinal materials at will, the pills will flow out?"

Li Mu cursed angrily and threw in a lot of the herbs in front of him.

"It's calculated as 9 first-class materials, which require a tower value. I don't know the result. Are you sure it's fused?"

"fusion"

Boom!

Another phew, obviously louder than the previous one.

Li Ying, who was standing next to Fang Zhong, heard the sound and hurried over.

"Brother, what were you doing just now? I want to play too."

As soon as the words came out, Li Ying also smelled the irritating smell, yawned, and shed tears.

Li Ying rubbed her nose, her face tensed, she tapped Li Mu twice, and then she skipped back.

Li Mu resisted the smell of the medicine and stuffed the two waste residues into the storage bag, and then the smell in the house gradually dissipated.

If you do it again, will it be just luck?

Li Mu was unwilling to give in. This time he stuffed enough herbs for more than 20 kinds.

"It is calculated that there are 23 first-class herbs, which require three tower points. The result is unknown. Are you sure you need to fuse it?"

"fusion"

"The materials do not meet the requirements and are merged into useless materials. Please change the materials."

When the tower mouth was opened, a piece of waste material flowed out. It looked like a black mass, which was very ugly.

Li Mu didn't want to smell it, so he just threw the waste into the storage bag.

Fusion, fusion, fusion.

Very quickly, the tower value was completely consumed, but in the end, there was nothing.

"I don't understand medicine, and I really can't. Should I learn how to make medicine first?" Li Mu stuffed low-grade spiritual crystals into the spiritual pagoda and muttered to himself.

After a moment of silence, Li Mu decided to continue trying.

Alchemist refining is not that easy to do, but it is a very difficult skill in the world of cultivation. It consumes time, energy and property. Now Li Mu has no money. The main reason is that he can't do it with that time.

After a little experimentation, there is a possibility that these 70 kinds of herbs can be combined with pills.

Li Mu mustered up the courage to try five or six experiments.

"The materials do not meet the requirements and are merged into useless materials. Please change the materials."

The reminder sounded one after another, and the waste continued to flow out one after another, but Li Mu didn't even look at it, he just kept moving and threw the waste into the storage bag.

Time gradually passed, and the fateful spirit finally came to him.

There are seven points left in the tower value, but there is not a single low-grade spiritual crystal. It has not changed at all, but there are too many herbs, only a small half is used, and the rest are piled in front of me like a hill.

"It really is impossible."

Li Mu shook his head and retreated from the spiritual sea.

Even for a cultivator, such an experiment would make him very tired, and he would fall down on the bed a little numb.

Especially if you think about it, with more than 70 materials, even if you can refine a dozen good pills, how can you easily find them? Even if you try this thousands of times, it will be very difficult to find a good combination.

The probability of this is indeed very small.

The probability of pooping is even lower than that of a bird above your head.

Li Mu scratched his head, "Originally I thought it was a good way to earn spiritual crystals, but it doesn't look like it is good at all. How can I get spiritual crystals?"

Spiritual crystals are the foundation of everything and will always be in short supply. Now there are only three grains in average, which can only maintain practice for a short period of time.
