In the dark passage, Lu Xuan walked slowly.

When he came to a stone cave, he followed the old fox's instructions and opened the restriction outside the stone cave, a fierce monster rushed out, and was pulled back into the depths of the stone cave by the rune chain on his body.

He has long been accustomed to the fierce look of these ferocious beasts, strong on the outside but fucking on the inside, and calmly enters the cave.

In addition to the forbidden formation outside the stone cave, all the ferocious beasts locked in the forbidden area also have various magic weapons that block demon power and restrict movement. They have ten or three in one body, so Lu Xuan can easily deal with it.

"Be good, let me draw some blood."

Inside the cave was a giant 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 and lay obediently on the ground.

The sharp magic weapon easily passed through its black scales, and a blood fountain surged out from inside, and soon filled the magic weapon.

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 monsters and purify them.

The giant snake's blood is black and red, and it is extremely toxic. It feels like it feels dizzy and swelling when it is heard.

Pour it into the strange solvent, and suddenly, the black and red blood reacted violently in the solvent, and the color became deeper and deeper, as if he wanted to suck Lu Xuan's spiritual consciousness in.

He put away the blood of the demon snake and entered another cave that the old fox told him.

Open the ban and a weird toad the size of a millstone came into view.

The toad's skin is colorful and looks extremely toxic at first glance, and poisonous smoke gushes out during breathing.

It looked at the blood-drawing magic weapon that Lu Xuan stretched over. Although it did not react, its eyes were full of resentment.

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

Lu Xuan said to the toad monster with a smile on his face.

With a forceful push of your wrist, the needle-shaped instrument can easily penetrate the toad's thick skin.

The huge toad was in pain and his body trembled violently.

"Sorry, I've inserted the wrong position, start over again."

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

The toad beast hurt even more violently.

There was still no blood coming out of the magic weapon.

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

Lu Xuan looked a little embarrassed and pulled out the special blood-drawing magic weapon again. After repeating it several times, he finally pulled out a tube of colorful monster blood.

"Remember not to look at me with that look in the future, otherwise I will be nervous easily."

He smiled and said to the toad beast.

After the colorful blood is purified by a special solvent, it becomes another form of solution.

Colorful light balls floated in the solution, and the light balls were concentrated to the extreme, like stars.

He held his breath and poured the black blood that had been drawn from the giant snake into the container.

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

After contacting the black essence and blood, colorful balls of light exploded instantly like fireworks, leaving behind clusters of colorful flocs.

“Failed.”

Lu Xuan recorded the reactions of the two purified essence and blood in the book and sighed softly.

As for the mixed essence and blood after the failure, he casually took 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. This mixed essence and blood may be a great tonic for it."

Lu Xuan took the mixed essence and blood into his pocket without hesitation.

He has been assisting Qingqiu Fox Spirit Beast in the experiment of ferocious beasts for some time.

During this period, what he did every day was very simple. At the beginning, he observed the monsters in their reproductive state and found ways to maintain their intercourse.

As he gradually became familiar with the state, the old fox became more and more trusting in him, he began to ask him to extract the blood of the monster beast ferocious beast. After special solvent treatment, he observed whether the blood of the selected monster beast could produce a benign reaction.

However, every experiment ended in failure. Lu Xuan did not dump the failed test items, but instead put them in the Taozhu sac and found an opportunity to feed them to the underworld spirit plants such as the Blood Evil Flower, the Blood Spirit Palm Ginseng.

During the experiment, he had seen the diversity of monsters' blood.

The various essences and blood have different colors and huge differences in characteristics, which gives him a good understanding of the monsters in the world.

After he worked diligently to complete the blood draw work day after day, the Qingqiu Fox Spirit Beast once again increased his workload.

"You have something to do in the future."

It found Lu Xuan, and its voice seemed to be getting older and weak.

"Senior, please speak."

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

"I guess you already know that there are many ferocious beasts and evil beasts in the forbidden area. These strange beasts are made by transplanting and suturing the torso, limbs and heads of different ferocious beasts."

"What I want you to do is to raise and take care of these sutured beasts, record their detailed status in a timely manner, and contact me anytime if an abnormality occurs."

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

"I understand it."

Lu Xuan nodded.

He followed the old fox's guidance and went to the bottom of the pit to find the special monsters with transplanted organs and even bodies.

Entering the cave, what appeared in front of him was a multi-clawed octopus. Dozens of tentacles lying on the ground like a pool of mud. The pupils of a monster were transplanted at the top of each tentacle, and most of the sutures were stinky pus.

Lu Xuan took out a pile of water monsters and piled them in front of the multi-mesh octopus.

The octopus beast lifted a tentacle weakly, opened its pupils at the top, grabbed a spirit fish more than half a foot long, and put it into its mouth.

After eating one, I closed my eyes and couldn't get any interest in the remaining monster meat.

"There is something wrong with this situation."

When Lu Xuan saw the strange beast reacting like this, he knew something was wrong, and his spiritual consciousness was condensed on the strange beast's body.

Suddenly, a thought came to his mind.

[Unknown strange beast, grade 4, fourth-grade black breathing giant chapter merged into the stitching of the thousand-eyed demon's eyes, and unknown changes occurred in the body.]

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

"I didn't expect that I could indeed see the detailed status of the transplanted and sutured ferocious beast."

Lu Xuan was happy at first and realized the power of his special ability again.

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

"It's no help, wait for death."

He looked at the weak octopus beast lying on the ground of the cave, and made a death verdict for it, and recorded his own judgment.
Chapter completed!
