Without the impact of the foreign body collision and the tearing sensation of flesh and blood being devoured, Yuhiri only suffered the bulging sensation of his blood vessels being stretched open at this moment.

Although it is still very uncomfortable, this level of pain is much better than before.

Yuhiri breathed a soft, silent sigh of relief, temporarily relaxing his tense nerves.

However, this calm did not last long.

Soon, a new, more intense wave of pain erupted from the crater like rolling lava.

The black spider in his body was like a mad cow with madness, and began to rush into the veins wantonly.

The thin walls of the blood vessels obviously couldn't resist such a violent impact, and they were instantly knocked out of one blood hole after another.

Yuhiri could feel that his blood vessels had become broken, and the thick blood was mixed together, shattering all the meridians and veins in his body.

The clenched teeth were too hard, and the pale pink gums had already become red and swollen, and even wisps of blood oozed from the joints between the root and the gums.

Looking at the unusually painful appearance of Yuhiri, Hehndo couldn't help but frown.

This is not the first time he has used blood piercing, nor is it the first time he has seen patients endure intense pain.

Heundo thinks he knows a lot about the pain of using bloodpiers. In his memory, the pain didn't seem to be enough to cause the patient to react so violently.

Although, due to the passage of the magic power in his body, Yuhiri now only has the strength of the Blood Baron, but the strength of his body has not weakened with the weakening of his strength.

It stands to reason that he could withstand such pain, and even his reaction would not seem too violent.

Just as Heindo was about to suspend his treatment and induce the black spider in Yuciri's body in advance, an accident happened.

At his left temple, a spherical bag bulged high, and the bag seemed to be wrapped around a living creature, and it jumped one after the other with great agility.

At first, the bag moved very fast, like some kind of poisonous insect with many feet, and in a short time it went down Yuciri's forehead to his right temple.

However, after just over ten seconds, the big bag seemed to be tired, moving at only a tenth of the speed of its previous movement, moving under the skin of Yuhiri's upper body at an extremely slow pace.

After about half a minute, the slow-moving bag completely stopped, and lay on its ground as if it had lost its life, no longer moving.

After waiting for a long time, Heindo finally couldn't help but cast a spell to lure the blood thorn out.

However, the spell that had been tried and tested in the past failed at this moment.

He continued to cast it several times in succession, but the blood thorn did not react in the slightest, and it still lay dormant.

Herndor had a bad feeling in his heart, and he walked quickly to the medicine cabinet, opened the second drawer on his left, and his hands trembled slightly as he went to a polished yellow wooden box.

Despite the conjecture in his heart, when Heundo saw the female Gu worm lying on her back on the brocade cloth surface with her white belly turned over in the box, his heartbeat suddenly stopped for a moment.

The female Gu in the box and the sub-Gu planted in the black spider's body are accompanied by each other, once the female Gu dies, then the sub-Gu will not be able to survive.
