Heundor carefully took out a spider the size of an adult's fist from the black sandalwood box beside him.

He first placed the spider in the palm of his hand, gently stroking its fluffy body, and whispered something that people couldn't understand.

"Remember, no matter how much pain you have to wait, don't make a sound." Heindo admonished to Yuciri.

This black spider comes from the extremely cold places of Northern Europe, where it is covered with snow and ice all year round, and there are few animals and plants.

However, such a cold environment has become a paradise for blood thorns.

The reason why these black spiders are called bloodthorns is not because they have long, bright red spines on their bodies.

Rather, it is because they can easily burrow into the thin walls of blood vessels, and travel quickly and sensitively along the bloodstream.

Bloodthorns live on blood, and when they are hungry, they can even drain the blood of an elephant at a time.

The bred blood spikes are no longer as aggressive as wild ones, and can burrow into the patient's body under the guidance of a wizard, and follow the blood vessels all the way to remove the blood block.

However, there is one aspect of such a special healing process that is extremely dangerous. That is, the patient cannot make any sound during the whole process.

Because once the bloodthorn is disturbed by anything other than the owner's voice, the wild nature hidden in it will be completely stimulated. At that point, it will be completely out of control, and even the owner will not be able to control the bloodpricks that are completely out of control.

However, from the blood thorn burrowing into the bottom of the skin along the texture of the skin, to the time it pierces the thin walls of blood vessels and sneaks into the bloodstream, to the way it swims in the direction of blood flow, devouring the blocking obstacles within.

The whole process is extremely long and painful.

Very few people are able to suppress a violent physiological reaction and hold back from crying out in pain. And once the sound is made, the blood thorns in the body will be stimulated and lose control, and that person will also be threatened by life.

Heindo explained these consequences to Yuhiri.

After all, this kind of suffering is not something that everyone can bear, and he must inform him first and let him make his own decision.

Without much hesitation, Yuhiri nodded in agreement.

What Yuhiri could not afford more than the uncertain risk was the loss of the power of magic. For his endurance, Yuhiri was still somewhat confident. He was convinced that he could get through this painful treatment process and held back his voice.

So Heindo gently placed the black spider in his hand on the neck of Yuciri, where there were distinct lilac veins, which were most suitable for blood thorns to enter.

Despite all the preparations, Yuhiri was almost screaming at the sudden pain when the bloodstab's front claws pierced the fragile walls of the veins, and the massive body squeezed into the narrow veins.

His already pale face faded to the last trace of blood, his thin pale red lips turned pale from clenching down, his hands clenched into fists, and ten long, sharp nails stretched out uncontrollably, and they were stuck into the tender flesh of his palms, dripping with blood.

The healing process was like years for Yuciri, and he felt his will crumble inch by inch, and he almost couldn't suppress the pain that was about to burst out of his mouth.

Just when he was on the verge of his limit, the black spider suddenly stopped wandering
