Martial Sovereign of Myriad Realms

I didn't say this in the materials I bought.

Yang Yan looks at Ye Feng and doesn't seem to know the furnace burst. It's strange.

But without much thought, he nodded and said, "yes, the more advanced materials, the more difficult it is to integrate with other advanced materials. Once it is not well controlled, the power of various advanced materials will burst out uncontrollably and then explode."

"Although the furnace has Dharma array blessing, those materials explode inside the furnace, which will cause some damage to the furnace."

"Over and over again, it will explode sooner or later. Even if it doesn't explode, the quality of refined spirit tools will be affected, and there is a great chance of defects."

"Oh... I know, thank you. Then take more." Ye Feng nodded.

Seeing this, Yang Yan said with a wry smile, "young master ye, your grade is really better than when you didn't use the furnace.

Most of the several ground level spirit tools are top-grade, and even a spirit sword, which has reached the level of the best.

Three days later.

After being familiar with using the furnace, Ye Feng really began to refine the first heaven level spirit weapon.

"The strength and strength of the material of the heavenly level spirit weapon have increased a lot, which is much stronger than previously estimated, and the melting time is several times longer than that of the earth level."

"At this speed, it takes at least several days to refine a heaven level spirit tool completely under normal circumstances."

When he really started refining, Ye Feng felt that it was very difficult to refine heavenly things as the standard for promoting a master.

The earth level spirit tool, he can control it as he likes.

But on this day, it takes a whole day to refine this level alone.

This is only the inferior material!

"Hey, I took my previous idea for granted. Now it seems that refining holy soldiers will only be more difficult. No wonder holy soldiers are so rare."

Ye Feng whispered to himself.

Just refining these materials made his forehead full of sweat.
