Immortal cultivation starts with copying.

After returning to the cave, Chen Yunhao made some preparations and started his first spiritual weapon refining.

Start with the alchemy furnace. Don’t feel bad if it breaks. At worst, you can just buy another spiritual-grade alchemy furnace.

Since refining the void, Chen Yunhao's Samadhi True Fire has become increasingly powerful.

Because his Samadhi True Fire is combined with the spiritual fire, and after so many years of nurturing, it becomes more spiritual.

Chen Yunhao has achieved such great success in alchemy and refining, and this Samadhi True Fire has played a big role.

The alchemy furnace that Chen Yunhao was going to refine again was the one he used most often in the lower realm.

Including the first rejuvenation pill he refined was also made using this furnace.

The unactivated alchemy furnace is only the size of a clay pot and can be held in one hand.

Chen Yunhao threw the alchemy furnace into the air in front of him, and the furnace floated in the air and slowly rotated.

Then Chen Yunhao pointed with two fingers, and a ball of spiritual fire appeared out of thin air and began to slowly burn the alchemy furnace.

The first step Chen Yunhao had to take apart the alchemy furnace, keep the useful spiritual materials, remove the useless ones, and then add some other high-level spiritual materials.

In addition, during the decomposition process, you can also see how the original alchemy furnace was refined, how many array patterns were used, and how many array patterns were superimposed.

A stone from another mountain can be used to polish a jade, and there is nothing shameful in learning from others.

The process of decomposing magic weapons is time-consuming and not as fast as refining pills.

Even though Chen Yunhao's Samadhi True Fire was quite powerful, it still took him nearly three hours to disassemble the alchemy furnace.

Using the special techniques from the Tiangong Bailian Technique, after three hours, the entire furnace turned into seven or eight balls of spiritual materials of different colors.

After Chen Yunhao identified them one by one, he only kept two of them and discarded the remaining spiritual materials.

These kinds of spiritual materials are all from the lower realm, and the space in which the alchemy furnace made with them can rise is already fixed.

Therefore, if you want to refine a spiritual weapon and keep the spiritual energy constantly upgraded, the initial spiritual materials cannot be too bad.

Of course, Chen Yunhao doesn’t have any very good high-level spiritual materials in his hands now. Some of them were collected by him after he came to the spiritual world, and some of them were bought from the spiritual material shops in the city.

Most of the spiritual materials obtained through these channels are ordinary goods, and there are relatively large stocks in the spiritual world. Rare things can only be obtained at auctions or private transactions.

Of course, there are several other channels. You can either pick it up by luck or enter some secret cave to get it.

Of course, the most reliable and secure thing is what Chen Yunhao is going to do now, which is to become a high-level weapon refiner so that all kinds of spiritual materials can be easily obtained.

As long as the spiritual materials pass through his hands, there will no longer be the question of whether the quantity is sufficient.

Instead of fighting for your life and risking your life to enter the secret realm, it is easier to be a weapon refiner or an alchemist. It is easy to make a living by mastering a skill!

Most of the spiritual materials have been removed from the furnace, so it is actually no different from refining it from scratch.

It’s not that Chen Yunhao wants to do this unnecessarily, but he has to do it. Only by becoming proficient in it can his refining skills be gradually improved.

Chen Yunhao took out several spiritual materials unique to the spiritual world. According to the characteristics of the alchemy furnace, these were all spiritual materials that were more resistant to high temperatures and easier to absorb spiritual energy.

First, all these spiritual materials must be refined. When in the lower realm, Chen Yunhao can do a second refining.

But in the spiritual world, three refinements are merely passing.

Of course, when he was in the lower realm, Chen Yunhao did not master the advanced weapon refining techniques, nor did he have any way to break through the threshold of three refinings.

This problem no longer exists. When he practices on the floating island, he can refine it up to five times.

For example, one of the spiritual materials weighed 100 kilograms in his hand, but after the first refining, it shrank to 50 kilograms.

After the second refining, it shrank to 25 kilograms, and after the third refining, it was only 13 kilograms.

After being refined three times, the spiritual material still contains many foreign impurities and is not pure.

After the fourth refining, only eight kilograms were left.

Chen Yunhao can barely complete five refining steps, and in the end he will get five kilograms of spiritual materials with very high purity.

Refining a large spiritual tool like an alchemy furnace consumes a lot of spiritual materials. Often, hundreds or even thousands of kilograms of a certain spiritual material are required, and after the last five refinings, only twenty or thirty kilograms can be obtained.

It would be impossible for him to refine thousands of kilograms of spiritual materials in one go; he had to refine them in batches.

If you think about it, this process is extremely long, and it is completely different from alchemy.

This time, when refining the alchemy furnace, Chen Yunhao selected a total of eight spiritual materials.

These eight kinds of spiritual materials also have primary and secondary distinctions. They must be clearly distinguished as to which are the main materials, which are the secondary materials, and which are purely scraps.

It took Chen Yunhao more than ten days just to refine these spiritual materials.

There were eight kinds of spiritual materials of different colors and sizes placed before him. The smallest was as big as a fist, and the largest was almost as big as a millstone.

Before refining, Chen Yunhao didn't expect it to be so time-consuming, but it was because he underestimated the melting point of high-level spiritual materials in the spiritual world.

To put it more intuitively, Chen Yunhao's Samadhi True Fire is now a little behind.

This is also a problem that is holding us back, but it is not easy to solve in a short time.

Because he practices both fire and thunder, if his cultivation level is improved, the power of Samadhi True Fire will naturally increase as well.

This type of advancement is relatively slow. There is another method, which is to find another spiritual fire, use the Samadhi True Fire to devour it, and refine it.

This method can quickly increase the power of Samadhi True Fire by one or two levels.

Spiritual fire is the spirit of heaven and earth. It is a rare thing whether in the lower world or the spiritual world. It is not easy to come across. It requires opportunity.

After all the spiritual materials are refined, just like alchemy, the various spiritual materials are melted one after another and then mixed together.

It is easier said than done to perfectly blend them together, but it took Chen Yunhao three days to complete the whole process.

Refining equipment not only takes time, but also energy, and consumes nearly 20% of the spiritual power in the body.

Of course, this was his first time refining a spiritual weapon, so the whole process was a little slow and not so smooth.

Once he becomes fully proficient, the time will be shortened and the consumption of spiritual energy will not be so great.

When all the spiritual materials are perfectly integrated together, the next step is shaping, that is, forming the shape.

This shaping must be based on the shape he has in mind, and it must be transformed using the unique hand gestures in the Tiangong Bailian technique.

Chen Yunhao looked solemn, with different hand gestures in each hand, and rays of spiritual power with light were absorbed into the spiritual material.

The spiritual material, which had already turned into liquid, rolled and surged like waves as the light sank in, and slowly the shape of the alchemy furnace emerged.
