At this time, Mufeng and Xu looked at each other, nodded, and sat cross legged in front of the smelting pool.

At the same time, the whole body of the two people is also spiritual power surging, strong breath fills all around, so that the surrounding hot air is solidified in an instant.

Then, a blue and a purple magic power was injected into the runic array above the smelting pool. All of a sudden, the flame produced by the smelting pool completely shrouded the four seemingly huge pieces of black gold and kept burning.

...

after a few hours, old Xu and Mufeng were both sweating, and their hands were pouring spiritual power into the light array in front of them, so that the smelting pool could play its role to the greatest extent.

And the effect is also remarkable.

Although it is a very rare metal with a high melting point, the flame temperature produced by the smelting pool has already reached the highest peak under the support of two masters' huge spiritual power, and the black gold in the pool is gradually melting now.

More than ten minutes later, the black gold in the smelting pool has completely become liquid, occupying one third of the height of the whole pool.

At this time, Xu was the first to stop and meditate to recover the spiritual power consumed. However, Mufeng still did not stop delivering spiritual power.

After all, his current strength is far more than that of old Xu, enough to support a long time.

After seeing the rest of old Xu, Mufeng also had an idea at the moment. Then, a seemingly huge mold appeared in front of him out of thin air.

Then, under the control of strong idea of Mufeng, it was suspended in the middle of the smelting pool.

Then, I saw that Mufeng's hands began to make a series of marks. Then, it was seen that the liquid black gold in the smelting pool was also like silk threads converging towards the mold.

After a short period of more than ten minutes, the liquid black gold in the smelting pool is completely absorbed by the mold suspended in the air.

And at this time, Mufeng's whole body was full of aura, and a aura in his hand was directly shooting towards the mold.

"Bang!"

Suddenly, the sound of an explosion came out. I saw that the previous mold had been directly fragmented in the explosion and fell to the ground. At the same time, in the middle of the air in front of the Mufeng, a combat spear that looked black and emitting special fluorescence was constantly rotating in its original place.

The whole battle spear looks about two meters long. The spear head is huge and sharp. If you look carefully, there are small serrations on both sides of the spear head. At the moment, the spear body also seems to be full of thick feeling. If you look carefully, there is a very unique groove in the middle of the spear body. From the groove, you can clearly see that it is in the spear body There's a relatively thin inner part of the spear.

At the moment, judging from the appearance, the whole spear is covered with mysterious patterns, which gives it a different aesthetic feeling.

Of course, this is only the most basic step. After that, there are many procedures, and this spear can be regarded as a complete success.

"Well, I finally finished the most difficult first step. I didn't expect that the smelting intensity of black gold was so high that I could hardly bear it. Thanks to your help, otherwise, just relying on my words, there would be no extra spiritual power to complete the later steps."

At this time, the spear suspended in the air was slowly placed on the ground by the force of mind, and the whole person was relieved by the wind.
