Iron Source Gu! Ancient Poison Rune Proficiency Level! Fire- and Poison-Type Gu Insects!

"Wait, I think I've seen records about these Iron Sheet Insects before."

Wang Teng suddenly recalled something. All sorts of information flashed through his mind like a computer constantly identifying and filtering data.

He had mastered far too much information. Building that Memory Palace truly needed to be put on the agenda.

"Found it—Iron Source Gu!"

A moment later, a sharp glint flashed through Wang Teng's eyes. He had finally found the relevant information.

Iron Source Gu!

This was a special kind of Gu insect that could absorb iron-based metals and transform them into its own body, possessing extremely powerful offensive strength.

Moreover, the harder and sharper the iron-based metals it absorbed, the harder and sharper its transformed body would become, and the more powerful it would be.

Gu insects also had another trait: they could strengthen themselves by devouring one another.

Raising Gu! Raising Gu!

Through the mutual devouring of countless Gu insects, one could raise the strongest Gu insect of all.

Wang Teng's Six-Winged Celestial Devil Gu Insect could do the same, but unfortunately, Six-Winged Celestial Devil Gu Insects were too rare. It could not devour its own kind and could only devour other Gu insects.

"So this is an Iron Source Gu."

Wang Teng examined the Gu insect before him and compared it to the information in his mind, finally confirming its identity completely.

He had once obtained a Gu Poison Secret Art from the Lan Family, a core poison-path family of the Sub-Profession Alliance Headquarters. It contained records related to this creature.

Just now, he had found information about the Iron Source Gu within that Gu Poison Secret Art.

Moreover, the Gu Poison Secret Art not only contained basic information about the Iron Source Gu, allowing one to identify it, but also included its refinement method.
