Li Chen had actually been suspicious for a long time.
The Netherworld and other Super Gu seemed a little different. Although Bug Cocoons appeared similar when disguised, the Netherworld that hatched looked completely different from those Super Gu.
The first Super Gu that Li Chen encountered had a hypnotic effect and seemed quite sluggish, much like a worm, but the Netherworld that hatched was a praying mantis.
Although unlike other Gu insects, the Netherworld was raised with his blood, the Netherworld still possessed characteristics entirely different from other Super Gu.
It was only at this point that Li Chen remembered that when the Netherworld was born, it was at his most dangerous moment, just a hair's breadth from death at Zi Zhao's hands.
At that moment, what he needed was a powerful attack to block Zi Zhao's blow.
The Netherworld succeeded, even severing Zi Zhao's finger.
Perhaps, it was entirely the Netherworld's own intention, not the result of natural evolution.
