In the dark passage, Lu Xuan walked slowly.

Coming to a stone cave, according to the old fox's instructions, the spiritual power opened the prohibition outside the stone cave, and a fierce demon beast pounced fiercely, and was pulled back to the depths of the stone cave by the rune chain on its body.

He was now accustomed to the lust of these fierce beasts, strong on the outside and dry on the inside, and entered the stone cave with a calm expression.

All the fierce beasts locked up in the forbidden land, in addition to the forbidden formation outside the stone cave, also have all kinds of magic weapons on their bodies that prohibit demonic power and restrict movement, and their strength is not three, Lu Xuan can easily deal with it.

"Well, let me draw some blood."

Inside the stone cave was a huge black snake with a pair of heads, looking at Lu Xuan fiercely.

Seeing the special blood-drawing magic weapon in his hand, his huge body couldn't help but tremble for a moment, and obediently lay on the ground.

The sharp artifact easily passed through its jet-black scales, and a fountain of blood gushed out from inside, quickly filling the artifact.

After Lu Xuan finished drawing blood, he took out a bottle of solvent filled with a strange smell from the storage bag.

This is a special solvent given to him by the old fox, which can fuse the blood of various demon beasts and purify them.

The blood of the giant snake is black and red, and it is extremely poisonous, and there is a feeling of dizziness when you smell it.

Pouring it into the strange solvent, all of a sudden, the black and red blood reacted violently in the solvent, and the color became deeper and deeper, as if it was about to suck Lu Xuan's spiritual sense into it.

He collected the blood of the demon snake and entered another stone cave that the old fox had ordered.

Turning the ban open, a monstrous toad the size of a millstone comes into view.

The toad's skin is colorful and extremely toxic at first glance, and there is poisonous smoke gushing out of the breath.

It looked at the blood drawing magic weapon stretched out by Lu Xuan, and although it didn't react, its eyes were full of resentment.

"Don't look at me like that, I'll be nervous."

Lu Xuanpi said to the toad demon beast with a smile.

With a strong push of the wrist, the needle-like instrument easily penetrated the thick skin of the toad.

The huge toad was in pain, and its body trembled violently involuntarily.

"I'm sorry, I plugged it in the wrong place, start over."

He pulled out the artifact, picked it left and right for a moment, and then stabbed it into the toad's body.

The toad beast was in even more pain.

There was still no blood coming out of the artifact.

"It's a bit of a handiwork, and if you try a few more times, you'll definitely succeed."

Lu Xuan looked a little embarrassed, and once again pulled out the special blood drawing magic weapon and inserted it, and after repeating it several times, he finally pulled out a tube of colorful demon beast essence blood.

"Don't look at me like that in the future, or I'll get nervous easily."

He said to the toad beast with a smile.

Colorful blood is purified by a special solvent to become another form of solution.

There are colorful light clusters floating in the solution, and the light clusters are concentrated to the extreme, like stars.

He held his breath and poured the jet-black essence blood he had drawn from the serpent into the container.

In an instant, a violent reaction of the solution is triggered.

After coming into contact with the jet-black essence blood, the colorful light clusters exploded instantly like fireworks, leaving behind clusters of colorful flocculents.

"Failed."

Lu Xuan recorded the reactions produced by the two purified essence blood in the book, and sighed softly.

As for the mixed essence blood after the defeat, he casually put it into the gluttonous sac.

"It's quite appropriate to take it back and feed it to the Blood Evil Flower, anyway, it's an evil spirit plant, and this mixed essence blood may be a great supplement for it."

Lu Xuan unceremoniously pocketed the mixed essence blood.

He had been assisting the Qingqiu Fox Spirit Beast in conducting fierce beast experiments for some time.

During this time, what he did every day was very simple, at first he was to inspect the demon beasts in their breeding state and find a way to maintain their mating.

After slowly getting familiar with him, the old fox trusted him more and more, so he began to let him extract the essence blood of the demon beast, and after special solvent treatment, he observed whether the selected demon beast essence blood could produce a benign reaction.

However, every experiment ended in failure, and Lu Xuan did not dump and destroy the failed test samples, but put them in the gluttonous insect sac, looking for an opportunity to feed them to the blood evil flower, blood spirit palm ginseng and other spiritual plants in the underworld.

In the course of the experiment, he could be regarded as seeing the diversity of the blood of the demon beasts.

The colors of various essence blood are very different, and the characteristics are very different, which gives him a good understanding of the demon beasts in the world.

After he conscientiously completed the blood drawing work day after day, the Qingqiu Fox Spirit Beast once again increased his workload.

"There's still something for you to do in the future."

It found Lu Xuan, and its voice became more and more old and weak.

"Senior, please speak."

Lu Xuan had already adapted to the way the two got along, and said respectfully.

"You must already know that there are many special beasts and evil beasts in the forbidden land, and these strange beasts are transplanted and stitched together with different beast torso and limbs, and head."

"What I want you to do is very simple, is to raise and take care of these stitched beasts, record their detailed status in time, and contact me at any time if something abnormal happens."

After the old fox finished speaking, he threw Lu Xuan a blue and black talisman, which seemed to be made of its own fur, and there was a delicate and soft touch similar to skin in his hand.

"The juniors are clear."

Lu Xuan nodded.

He followed the old fox's guidance and went to the bottom of the pit to find those special demon beasts that had been transplanted with organs and even bodies.

Entering the stone cave, what appeared in front of him was a multi-clawed octopus, dozens of tentacles lying on the ground like a puddle of mud, and the top of each tentacle was transplanted with a demon beast eye pupil, and most of the suture parts were bleeding fishy pus.

Lu Xuan took out a bunch of water demon beasts and piled them up in front of the multi-eyed octopus.

The octopus beast weakly raised a tentacle, opened its pupil at the top, grabbed a spirit fish more than half a zhang long, and sent it into its mouth.

After eating one, he closed his eyes, and he didn't have the slightest interest in the remaining demon beast meat.

"There's something wrong with this."

Seeing the strange beast's reaction like this, Lu Xuan knew that something was wrong, and his spiritual sense was condensed on the body of the strange beast.

Suddenly, a thought came to his mind.

[Unknown Beast, Grade 4, Grade 4, Grade 4 Black Breath Giant Chapter is integrated into the suture of the Thousand-Eyed Demon Pupil, and unknown changes occur in the body. 】

[Due to the rejection of spiritual power, the vitality is weak and is about to be extinguished. 】

"I didn't expect to see the detailed state of the transplanted and sutured beast."

Lu Xuan was overjoyed at first, and once again realized the power of his special ability.

"It's a pity that you're just a product of failure."

"It's hopeless, wait for death."

He glanced at the weak octopus beast lying on the ground of the stone cave, gave it a death verdict, and recorded his judgment with his hand.

"With this ability, those experimentally transformed beasts in the forbidden land will have no secrets under my nose, whether they are alive or dead, how to save them, they can be seen at a glance, and they are naturally suitable for this kind of experiment."
