After entering the cultivation room, Lei Xiaotian first sorted out the refining materials he bought, selected a set of materials needed to refine the Flying Eagle Battleship according to the requirements of the drawings from the middle, then sat cross-legged, read the drawings again, and then closed his eyes and began to demonstrate the refining process in his mind.

Refining a battleship is actually a refining weapon, refining tools are different from refining medicines, if refining medicine fails, all medicinal materials will be destroyed in a flash, but refining weapons are not like this, for example, refining a sword, even if it can't achieve the original expected effect, but you can always get a sword, even if you can't get a sword, those materials will not be all destroyed, after all, even if it fails, those metals are still there, and they will not be burned into nothingness like medicinal materials, after all, even if the metal is turned into water, after the final cooling and condensation, it is still the original metal, but the shape has changed。

Lei Xiaotian thought carefully about the refining process in his mind, then stood up, took out his refining furnace, and began to input fire energy into it, Lei Xiaotian's refining furnace was still found in the Demonic Beast Forest of the Southern Desolate Continent from the cemetery of the Heavenly Machine Law God when he was in the Shengya Plane, and it was also a treasure in the Shengya Continent, but to refine the battleship, this refining furnace was obviously not suitable, because its internal space was not large enough.

It was only when Lei Xiaotian took out the refining furnace that he took this problem into consideration, which was also something that Lei Xiaotian hadn't thought of before, after all, Lei Xiaotian had never refined such a large item as a battleship before.

Thinking of this, Lei Xiaotian smiled bitterly, then sat down anew, and began to think, Lei Xiaotian knew that now he had to refine a refining furnace before he could refine the battleship.

Refining Furnace Lei Xiaotian is no stranger, but to refine the refining furnace, it is just necessary to use the Empty Soul Stone to make the internal space of the Refining Furnace larger, fortunately, the Empty Soul Stone in the God Realm is not a cherished refining material, and refining a battleship also needs a lot of Empty Soul Stone, so there are a lot of Empty Soul Stones in Lei Xiaotian's hands.

As for the other materials needed to refine the refining furnace, over the years, among the White Tiger Tribe, Lei Xiaotian has obtained a lot, of course, they are not too advanced, but it is enough to refine a refining furnace that can be used to refine battleships.

As for designing a refining furnace, it was so difficult that Lei Xiaotian couldn't defeat it, so next, Lei Xiaotian spent a day designing a refining furnace, and the shape of this refining furnace Lei Xiaotian was the same as the Nine Dragon Ding designed and refined by Lei Xiaotian at the beginning, but the formation depicted was different, and the materials were also different.

After the design was completed, Lei Xiaotian took out the materials, and then sat down and closed his eyes for a while, Lei Xiaotian stood up again and began to refine the refining furnace, first of all, Lei Xiaotian first entered the fire energy into the original refining furnace, and after the temperature in the furnace reached the requirements, Lei Xiaotian began to put the main materials of the refining furnace, Lei Xiaotian has now comprehended the mystery of the temperature law in the fire system, so it is very easy to refine these materials.

After refining the main materials, Lei Xiaotian kept the temperature unchanged, and then threw the empty dark stone and other auxiliary materials into the furnace, after all the auxiliary materials were melted, Lei Xiaotian used his soul power to control these liquefied materials and began to fuse!

After fusing these materials, Lei Xiaotian began to control the temperature in the furnace and began to remove the impurities in these materials, this step was relatively easy for the refiner, and it took a total of three days to complete this.

After removing the impurities in the materials, Lei Xiaotian used his soul power to control these liquid materials and shape them according to his own design, Lei Xiaotian must be careful at this step, after all, even if the refining furnace is not successfully refined, the volume is not small, Lei Xiaotian can't let the newly refined refining furnace burst his original refining furnace when it is formed.

This step took Lei Xiaotian ten days to complete the formation of this step, and then, Lei Xiaotian began to depict the formation in the refining furnace, although this step needs to be fine, but those formations Lei Xiaotian has already been well understood, so when depicting, although Lei Xiaotian is not depicted quickly, there will be no mistakes.

First of all, in order to allow this refining furnace to change the size freely, the first thing Lei Xiaotian portrayed was the change circle of the gold system, and after it took three days to depict the change circle, Lei Xiaotian also came down easily, after all, now Lei Xiaotian will not worry about the size of the refining furnace.

Next, Lei Xiaotian continued to depict the formation in the refining furnace, what space system accommodates the magic circle, the repair magic circle of the fire system, the extension of the gold system, etc., Lei Xiaotian has continuously depicted dozens of magic circles in this refining furnace, until there is no place to accommodate the magic circle in the entire refining furnace, Lei Xiaotian stopped.

No matter what kind of artifact it is, when refining it again, the more advanced the material, the more magic circles it can hold, and after refining it successfully, the stronger the effect will be, which Lei Xiaotian has long understood.

After carving these formations, Lei Xiaotian once again used his soul power to warm up the refining furnace for a day, and then Lei Xiaotian took out some demonic beast crystal nuclei and embedded them on the refining furnace to provide energy for those magic circles.

You must know that the crystal nucleus taken from the body of the tenth-level divine beast can already automatically condense the aura of heaven and earth from the air, so even if some artifacts are placed anywhere, no one has used them for ten thousand years, and they can still maintain their own attributes.

It took five days again, and after inlaying the crystal nuclei into all the magic circles, this refining furnace was successfully refined, and after the refining was successful, Lei Xiaotian's heart moved, and he directly opened the lid of the furnace, and used his divine power to control the refining furnace in the furnace, and flew out of it.

Lei Xiaotian looked at the palm-sized refining furnace that flew out of his original refining furnace, Lei Xiaotian smiled with satisfaction, and Lei Xiaotian was more confident about the battleship to be refined later.

Next, Lei Xiaotian put away the original refining furnace, and then dripped a drop of blood on the refining furnace that had just been refined in his hand, and after completing the recognition of the master, Lei Xiaotian first controlled the refining furnace to become larger, placed it in the cultivation room, and casually injected some divine power into it, and experimented with the performance of the newly refined refining furnace.

After doing this, Lei Xiaotian checked the materials for refining the Flying Eagle Battleship on the side again, and then, he sat down again, began to close his eyes and recuperate, and at the same time recovered his state, after all, Lei Xiaotian also spent more than a month refining the refining furnace this time, and the consumption of divine power and spiritual power was not small, so he was ready to refine the battleship, and Lei Xiaotian naturally had to adjust his state!
