The heartlessness Gu in the Vermillion bird's body had actually been activated, and it was something that could take her life at any time.
All Gu worms had to absorb the blood essence of their owner. Which Gu master didn't sacrifice their own life to cultivate a powerful Gu worm?
Almost every year, there were many people in the Miao village who were exhausted to death by the Gu worms. This was because the larger the Gu worms grew, the more blood essence they needed. As the Gu cultivators grew older, their blood essence would become less and less. Especially after the age of 40, their blood essence would be pitifully little.
Not to mention a sentient Gu. Sentient Gu required even more blood essence, and the quality was extremely high. When the mass was not enough, they would increase the speed of absorption.
