He lifted his clothes and stripped off a large number of inactive black worms, only then could he see his lower back.

It was a finger-long one, just over two inches long...... Feather!

The feathers are red and white, incompatible, bright red on one side and white on the other.

It grew right out of his back lumbar spine, and if it wasn't higher, it looked like a strange short tail.

How do you grow feathers?

Yang Yu was a little puzzled.

When he was in Jinyang Pavilion before, in front of everyone's eyes, he didn't have time to take a closer look at those things he ate.

At that time, he only wanted to eat these disgusting things and leave quickly, so he only glanced at them in a hurry when he saw the item information.

As long as he made sure that no one was secretly calculating, it was all good and harmless to him, and then he used the purification and ate it into his stomach.

Now something so strange had grown on his body that he couldn't even remember what he had eaten.

He thought back to his mind that there was nothing feather-related to the things he was eating.

So where did this feather come from? Could it be that it appeared out of thin air?

He twisted his waist slightly and turned his gaze to observe, the feather growing on his body did not feel any weight at all, as if it did not exist.

The feathers grew out of his flesh diagonally upward, and near the bottom of the flesh was a cluster of fine down feathers, and the upper feathers split in two until the top of the flesh to show two different colors.

Yang Yu stretched out his hand and gently flicked it, but there was no feeling from his body, but an information box in front of him flashed away.

Got an infobox?

His eyes lit up suddenly, it was much easier to have an information box, and then he gently touched the feather with his hand, and the information box popped up again.

"[Spinal True Feather]: A flesh and blood rejuvenating thing that is born from a large number of spiritual things that promote the development of the body under a very small chance, connecting the flesh and bones and bloodlines, and can be used as weapons, the red feather is bloody and poisonous, and the white feather is sharp and can be attacked from afar; It is currently in its infancy and needs to be watered with blood from time to time before it can grow.

Cost of use: Because the object is connected to the marrow and bones of the body, long-term use will lead to the acceleration of blood circulation in the whole body, and the reflux of blood toxin into the body will lead to the poisoning of the body and death.

Status: Purifyable!"

Seeing the information displayed in the information box, Yang Yu looked back and forth several times, and finally determined that this thing did indeed grow from his body, and it was not a foreign thing, so he breathed a sigh of relief.

The so-called flesh and blood artifacts should be the genes of a certain species that may remain in this body.

Because he ate a lot of things that were good for his body, he happened to activate this little bit of genetic residue, so he grew this feather.

He tried to explain it with the scientific knowledge he knew, like some kind of genetics, and whether it was right or not, it probably wouldn't be much worse.

It's just that what Yang Yu didn't expect was that this feather could still be used as a weapon.

But that's too small, isn't it?

The only way he could think of a two-inch-long weapon was to shoot this thing out, and it happened that the feathers had blood poison on them, so maybe the enemy could see the blood and seal their throats.

I just don't know if this thing can be taken back after it shoots out.

Thinking of this, Yang Yu put his hand on the feather to purify it, planning to try it.

Since it is a feather, it means that it can be pulled out.

He pinched the feather with two fingers and pulled it with a little force.

"Shhhh

In the next second, Yang Yu straightened up on the spot and gasped!

The feeling of the feather being pulled out was like pulling the spine out of his body, although the pain was not painful, but it was very sore, and a pulling sensation went straight from the heavenly spirit cover to the tail vertebrae.

It wasn't until this sourness had passed that he was surprised that as the feather was pulled out, a large number of red veins were pulled out from the place where the feather grew, and the tendons were entangled, which was two fingers thick.

The veins were connected to his body and the tail of the feathers, and the bright red blood visible to the naked eye flowed rapidly in the veins, and the feathers in his hands were also rapidly enlarged in an instant.

With just one breath, the feather, which was originally only two inches long, swelled to more than a meter long in an instant.

And the feathers, which he could pinch with only two fingers just now, have swelled enough to be held in one hand, like the grip of a weapon.

Looking at the spinal cord true feather in his hand, which had become larger, Yang Yu understood what he meant by the information box that it could be used as a weapon.

He originally thought that this thing was too small and could only be used as a hidden weapon, but he didn't expect that it was unexpected, and it felt like holding a sword or a knife in his hand.

It was the blood transfusion veins that were pulled out of his body and connected to the feathers, and it seemed that there was no way to break it, so it could only remain implicated.

This feeling is a little weird, as if he is not holding a feather in his hand, but a part of his own flesh and blood, and he can also feel the most real touch.

Whew!

Ding Ding Ding!

Yang Yu took the spinal cord true feather in his hand and waved it a few times, and then flicked the left and right feathers with his fingers.

The reddish-white feathers have a metallic sheen, and even the sound sounds similar to metal, the texture is hard, and each individual feather looks very sharp and sharp.

However, this thing gave him the feeling that it was like an ordinary sword, and the hardness should only belong to a very ordinary level, which could not be compared with magic weapons.

Perhaps this has something to do with the juvenile stage described in the infobox, as the feathers have not yet reached a higher level of hardness, and can only be used as ordinary weapons, requiring blood irrigation to grow.

Yang Eucalyptus's gaze scanned the spinal cord true feather in his hand left and right, and the two colors, one red and one white, formed a stark contrast.

The blood poison on the red feather couldn't be tested for the time being, but he wanted to try the white feather's attack method.

In the next second, his mind moved.

Phew-

Several white feathers suddenly detached from the feather shaft and flew out from different directions and shot in front of him, making a sound that broke through the air in the air.

But at a distance of five meters from him, Bai Yu suddenly stopped, just stagnant in mid-air, unable to advance an inch.

At this time, Yang Yu saw that at the tail end of each white feather, there was a small capillary-like red line, and the other end was connected to the feather shaft of the true feather of the spinal cord.

It is precisely because of the involvement of these red lines that the limit distance that Bai Yu can fly out is only five meters.

Beyond this distance, the red line will straighten and cause a limit, making it impossible to move forward.

However, within this range of five meters, he could freely control these white feathers to fly around in mid-air.

It is quick and flexible when the mind comes and goes.

This is how White Feather attacks!

"Perhaps the distance that these red lines can reach is still related to the fact that the true feathers of the spinal cord are currently in the juvenile stage."

Yang Yu quickly came to such a conclusion in his heart.

Judging from this view, even if Red Feather hasn't tried, I'm afraid that the blood poison in it won't be too strong, and it still needs to grow.

After understanding how to use the spinal cord true feather in his hand, Yang Yu was ready to take this thing back.

The tendons connected to the feather roots are like a elastic elastic rope, and when holding the true feather of the spinal cord close to Yang Eucalyptus's waist, the tendons and veins quickly retract into Yang Eucalyptus's body.

"Shhhh

Yang Yu immediately felt a burst of sourness again, and rushed straight from the tail vertebrae to the Tianling Gai.

As the tendons and veins retracted into his body, the true feather of the spinal cord was also constantly shrinking and shrinking, and in the blink of an eye, it retracted back to its original length of two inches, and returned to Yang Yu's lower back.

As soon as his clothes were covered, I am afraid that no one would have thought that there was a large or small weapon hidden on his waist.

For the harvest of this apprenticeship banquet, if he removes the feeling of eating those things, then he must be very happy.

This spinal cord true feather can be regarded as an unexpected joy.
