Sky Swallowing Gu?

Blood Thorn: slightly bitter, grows in barren lands, and is greatly favored by certain Spirit Worms.

Zhou Feng picked up a sickle and began harvesting the wildly growing Blood Thorns.

Because they grew in barren lands, these Blood Thorns were exceptionally tough and difficult to remove. An ordinary person would have to exhaust themselves to cut two hundred jin in a short time.

But for him, it was a trivial task.

Even though his vital energy and blood were weak at the moment, circulating them and precisely controlling his body allowed him to exert strength far beyond what this body should possess.

"Circulating vital energy and blood works..."

"The methods for tempering the body work too..."

"But methods for drawing in spiritual energy don't?"

As Zhou Feng cut the Blood Thorns, he began experimenting at the same time.

Ordinary body-tempering methods posed no obstacles, but whenever he tried to cultivate qi, he would feel an ominous premonition from somewhere unseen.

It seemed that if he wanted to cultivate, he could only place his hopes on those so-called Gu insects.

In other words, he could only follow the Gu insect cultivation system. Any cultivation method outside that system was forbidden.

Avoiding danger was simple enough: combine it with Gu insects and create a new cultivation method.

"What about the Six Desires Demonic Scripture?"

Zhou Feng considered it and began trying another approach.

The Six Desires Demonic Scripture strengthened the soul through desire. Could such a miraculous technique deceive the heavens?

He began stirring the desires in his heart, but just as before, the hairs all over Zhou Feng's body stood on end, as though danger were about to descend.

"Still no good! What if I use a Gu insect?"

A simple attempt had failed, but Zhou Feng did not give up.
