Chapter 609 Territory Five

```

"According to the information on the Jade Talisman, the key factor in enhancing Dao weapons is Black Queal Gold. This substance can only be obtained by snatching it from the hands of void demon spirits."

"In addition, as Dao weapons continuously battle with void demon spirits, after killing the opponent, they can absorb some mysterious energy, allowing the Dao weapon structures to evolve themselves."

Lin Xin pondered to himself. He had already tried it. Since Dao weapons did not have souls, his Attribute Ability enhancement could not spread to them.

It was different when in the Underworld, where even an insect was essentially a soul creature.

These Dao weapons, on the other hand, were more like material life forms.

"The most fundamental characteristic of material life forms is that they can only be enhanced through materials. If I can refine a substance that can enhance them... perhaps I can also inscribe formation patterns on their bodies to strengthen them."
