Gu Yunnian and Yao Lao firmly fixed his limbs and waist with a strap that was the width of his palm.

"Let's get started!" Gu Yunnian's expression was solemn and he said in a deep voice.

Yao Lao turned around and lit the incense inserted in the incense burner, and a unique sweet fragrance permeated.

Gu Yunnian used a golden needle this time, surrounding the heart, blocking all the veins, densely packed.

After doing this, her forehead was already sweating.

Gold needles are more difficult to use than silver needles, and she has no internal strength now, so she can only rely on her hand strength to quickly lay down seventy-two needles in less than a minute, which is already her current limit.

It was this speed that Gu Yunnian was not very satisfied with, which shocked Yao Lao.

When Yao Lao's body was at its peak, it couldn't reach Gu Yunnian's height.

Gu Yunnian took out a bottle of turquoise potion and smeared it on the blank space of the heart surrounded by golden needles, and then took out a sharpened jade knife.

The jade knife cut a small but very deep cross directly above Ye Ze's heart, and the beating heart was faintly visible.

Then he took out a glass bottle the size of a thumb, and in the bottle was a pill the size of a little finger that was eerily red in blood.

Gu Yunnian dipped a cotton swab in Ye Ze's blood and smeared it on the pill, and threw the cotton swab into a sealed glass jar.

He wiped the bottle with the turquoise potion, and the upside-down bottle was aimed at the cross drawn by the heart, and the pill was still fixed at the bottom of the bottle.

Ye Ze's face turned pale for an instant, and he quickly showed a painful look and let out a muffled snort of pain.

Through the glass bottle, Ye Ze's heart could be seen suddenly rising, and every time he followed this movement, he would let out a painful snort, and his expression gradually became hideous and distorted.

His hands, feet, and body were trembling and twitching, and if it weren't for the help of the straps, I'm afraid he would have rolled in place in pain.

"How long will it take for Gu worms to come out?" Yao Lao asked worriedly, worried that Ye Ze would not be able to hold on.

He understood that the solution to the Gu was to use the bait to attract the Gu worms hidden in the heart, and the red pill was the bait.

For Gu worms to come out, they must bite through the heart to get out.

Feeling the heart being gnawed alive is also the reason why the Heart Devouring Gu relieves the pain of the Gu.

Yao Lao knew that Ye Ze was a very pain-tolerant child, and a child who could endure it like this could be like this, even if he looked at it, he couldn't bear it.

Gu Yunnian shook his head, his expression was slightly condensed, and his gaze did not leave Ye Ze for a moment.

"It's not sure, it's up to his luck. If the Gu worm happens to be on the side close to the wound......"

She didn't continue, Yao Lao already understood the meaning of her words.

Every minute and every second seemed to be a long time at this moment, and it was even more like a year on Ye Ze.

Ye Ze's painful sweat soaked the sheets, as if they had just been fished out of the water. The cries of pain blocked by the cork had become hoarse and could not be screamed.

The pupils were already a little dilated, and his consciousness began to blur, and he only remembered Gu Yunnian's instructions with a strong will to survive and stay awake.

Gu Yunnian's expression became more and more serious, his eyes were fixed on the wound, and even his breathing became gentle.

Looking at the protruding point of Ye Ze's heart, he finally broke a small dot, and a bright silk thread like blood drilled out, slowly climbed onto the glass bottle, and crawled towards the pill at the bottom of the bottle.

The Heart Devouring Gu's body elongated, like a red thread wrapped around the pill.

Gu Yunnian watched as the Heart Devouring Gu was completely pulled out of Ye Ze's heart and retracted into the glass bottle.
