After bidding farewell to their master and many friends and relatives on the island, Ye Li and Xiao Qing flew towards the Black Eye Continent again.
Although the materials for the Destroying Heaven Bow have been prepared, the foundry furnace still needs to be rebuilt.
Ye Li was actually a little nervous in his heart. He only had one set of materials to forge the Heaven-Destroying Bow, and it was very likely that he could only find this one set. If the forging failed, there would be no chance to try again.
Ye Li's bracelet also stores the world power that he found at the beginning. These world powers can be used to create three special arrows.
The thing that can truly deal with Dahuntian is not the Destroying Heaven Bow, but these three special arrows forged by the power of the world.
However, in order to shoot these three arrows, Ye Li had no choice but to use the Heaven-Destroying Bow, which is why he needed to forge the Heaven-Destroying Bow.
Now in order to cast a top-grade god-level casting furnace, Ye Li needs a lot of things.
The first thing to consider when making a god-level, top-grade casting furnace is the furnace's bearing capacity, because the higher the grade of the furnace, the higher the temperature of the flame it can release.
If one wants to forge a Dao-level Heaven-Destroying Bow, the flame temperature in the casting furnace must be incredibly high, and it may also need to be maintained for a long time.
Ordinary casting furnaces cannot withstand long-term high-temperature calcination and will quickly melt into water.
In addition, Ye Li’s plan is to use the foundry furnace to absorb the extremely rich power of the earth fire to forge the Heaven-Destroying Bow, so this foundry furnace needs to have a good absorption effect on the power of the earth fire.
It must absorb a large amount of earth fire power at all times, and also use the formation in the foundry furnace to expand and enhance the power of the earth fire and keep it stable.
Therefore, Ye Li also needs a lot of materials for casting fire talismans.
In addition, after some consideration, Ye Li thought that he should also add the power of wind, wood and yang to the casting furnace.
These three attributes can indirectly increase the power of fire.
He had never cast a talisman of the Dao level, but Ye Li was very familiar with Dao level materials. He was very clear about one thing, that is, Dao level materials were not so easy to melt.
Theoretically, the higher the quality of the material, the more difficult it is to melt and blend evenly with other materials. Among the nine avenue-level materials, even if not every one is particularly difficult to melt, there are definitely two or three that have a very difficult melting process.
Therefore, ensuring that the temperature of the flame in the casting furnace is sufficient is what Ye Li needs to do.
Ye Li sat on Xiao Qing's back and flew towards the mainland, thinking about casting the casting furnace along the way.
In order to ensure that the casting furnace can withstand high temperatures, Ye Li does not plan to use gold-based materials, because he knows very well that although gold-based materials are resistant to high temperatures, fire-based materials have a restraining effect on them in terms of properties.
Earth-type materials do not have the disadvantage of being restrained by fire-type materials, but most earth-type materials are not as resistant to high temperatures as metal-type materials.
Ye Li knew of an extremely high-temperature resistant earth god-level material called infusible stone.
This is a kind of stone that cannot be melted by flames at all. Even when it is used in a casting furnace, it cannot be melted in flames using ordinary methods.
To melt it, you have to use another special material, molten gold.
There is a folk saying that "turning stone into gold" actually refers to this special spiritual material "turning gold into gold".
This spiritual material has a very special property, which is that it can transform a certain stone into metal in a short period of time.
If Ye Li wants to melt the infusible stone, he must use the power of the alchemy liquid to turn the infusible stone into metal.
In this way, it will be restrained by the power of fire and can be melted into juice at extremely high temperatures.
After it is melted, Ye Li will change it into the shape of a casting furnace. The effect of the molten gold will soon wear off, and then the casting furnace will completely solidify and can no longer be melted by flames.
Therefore, the casting furnace made of non-melting stone is definitely the most fire-resistant, because flames cannot destroy it at all.
In addition, Ye Li also needs god-level materials of wind, yang and wood, but these materials are relatively common and not so difficult to obtain.
Ye Li had seen these materials several times in the past at the Chamber of Commerce or auctions. Although the prices were quite high, they were always available for purchase.
But the infusible stone is not so easy to find. Ye Li rarely sees this kind of thing in the Chamber of Commerce, so he can only ask for information about the infusible stone. As for the golden liquid, although it is a spiritual material, the finished golden liquid is actually mixed and refined with a special formula.
There is only one family in the entire continent that can refine the formula for the golden liquid, and that is the Jin family in Jueluo City.
The Jin family in Jueluo City is itself a large first-class family with a very long family history.
The location where the Jin family of Jueluo City is located happens to be a production site of elixir, which is a product of the fusion of certain stone and metal minerals.
If you want to use it directly, the effect is actually very poor. Even if the stone can be turned into metal, the time is very short.
If you want to keep the stone in a metallic state for a longer period of time, you need a elixir that has been refined according to a formula.
Although Ye Li does not need the non-melting stone to remain in the metal state for too long, a sufficient period of time is still necessary.
Otherwise he would not have enough time to melt the infusible stone and shape it into the shape of a furnace.
Moreover, the infusible stone needs to be fused with other materials and engraved with rune formations. The whole process takes quite a long time, so it is absolutely impossible to do it without the refined alchemy liquid.
To do this, Ye Li had to go to the Jin family in Jueluo City to buy or ask for some gold liquid from them.
Soon Ye Li flew into the continent. He did not choose to go to Qilin Ridge to check the brewing progress of Baiguoxiang Wine, but flew directly towards the central area of the continent.
Ye Li planned to go to Prajna Mountain first, because there were not many chambers of commerce left on the mainland, and some of them were still controlled by the Tianhun Society.
Ye Li thought that if he wanted to find a relatively rare treasure like the Infusible Stone, asking a powerful force might be the best option.
Prajna Mountain is powerful, but not many people know its true strength. With their background, they might have infusible stones in their warehouses. It is a good choice for Ye Li to go to them for help.
In addition, he also wanted to visit his mother. It was not easy for Feng Feiyan to lead the rest of the Feng family now.
After figuring out where to go, Ye Li patted Xiaoqing under him and instructed it to fly towards Mount Prajna.
A few days later, the man and the beast finally arrived at the territory of Prajna Mountain.
