Zuo Wenya was naturally surprised to hear that Lin Xinghai had developed another new Secret Technique.
Although developing simple Secret Techniques wasn't as difficult as creating Martial Arts, it still required immense experience and knowledge to achieve.
Moreover, he had seen the Perception Secret Technique Lin Xinghai developed, called the Investigation Technique. While the Investigation Technique wasn't overly complex, it was extremely ingenious.
It might not be of much use to experts of their caliber in the Divine Demon Realm, but its effects were very apparent for those at a lower Level.
This was especially true in areas with limited visibility, like the green Poisonous Fog Districts that had appeared, where its effects were immense.
But to Zuo Wenya, all of this was merely surprising.
The current gap in combat power between them and the Mutated Zombies couldn't be solved by a single Secret Technique.
It would require a qualitative transformation.
