From the past, swallowing gold and silver could increase the demonic power and slowly extend to other materials. This soul has been growing continuously.

But Li Hongru also gradually realized the need for the demon soul. After swallowing more than ten ingots of gold, he could not see any enhancement of this soul.

For the demon power of the iron-eating beast, simple materials can no longer meet the growing needs, and even the accumulation of quantity is difficult to produce effects.

In the food recipes of the growth of the iron-eating beast's demon power, this demand is constantly rising.

Li Hongru gnawed a lot of gold, and when he took the Heaven and Earth Banner and swallowed it repeatedly, he saw that the demon soul that had not moved for a long time began to hop, which made him feel relieved.

Better, harder, rarer...

As long as the materials are advanced, he can continue to improve the demon soul.

Li Hongru was also glad that he was not like an ordinary iron-eating monster, but only focused on things like gold and stone.

Because of Taiwu's needs, he now has a wide range of gnawing, including wealth, gold and stone, cloth, wood, medicinal materials, and even some of the foods that Taiwu needs are beneficial.

The variety of types gives him a further room for improvement.

Li Hongru also gnawed the big bag of the king's species.
