He ​​lifted up his clothes and peeled off a large number of inactivated black insects, only then could he see his lower back clearly.

It was a feather that was only as long as a finger, just over two inches long!

The feathers are red and white, which are incompatible with each other. One side is bright red and the other is pure white.

It grows right from the lumbar spine of his back. If it weren't positioned higher, it would really look like a strange short tail.

How do you grow feathers?

Yang Gu is a little confused.

When he was in Jinyang Pavilion before, in full view of everyone, he didn't have time to take a closer look at the food he was eating.

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

As long as he made sure that no one was plotting against him, everything was beneficial and harmless to him, so he purified it and ate it.

Now there are strange things growing on his body, so strange that he can't even remember what he ate to cause them.

He recalled it in his mind and found that among the things he ate, he didn't see anything related to feathers.

So where did this feather come from? Did it appear out of thin air?

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

The feather roots grow diagonally upward from his skin, and close to the bottom of the skin is a cluster of fine down feathers. The upward feathers are divided into two parts until the top, showing two different colors.

Yang Yu stretched out her hand and fiddled with it gently. She didn't feel any sensation in her body. Instead, an information box flashed in front of her eyes.

Is there an information box?

His eyes suddenly lit up. It would be much easier if there was an information box. Then he gently touched the feather with his hand, and the information box popped up again.

"[True Feather of Spinal Cord]: A flesh-and-blood ancient thing produced by a large number of spiritual things that promote body development with a very small chance. It is connected to the marrow and bone blood of the physical body and can be used as a weapon. The red feather is poisonous and the white feather is sharp.

It can be attacked from a distance; this thing is currently in its infancy stage and needs constant watering with blood before it can grow.

Cost of use: Because the substance is connected to the marrow and bone blood vessels of the human body, long-term use will cause the blood circulation throughout the body to accelerate, and the blood poison will flow back into the body, causing the body to be poisoned and die.

Status: Can be purified!"

Seeing the information displayed in the information box, Yang Yu looked back and forth several times, and finally he was relieved when he finally confirmed that this thing did grow from his body and was not a foreign object.

The so-called flesh and blood restored to ancient times should be that the genes of certain species may remain in this body.

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

He tried to use the scientific knowledge he knew, such as genetics, to explain this matter. Regardless of whether it was correct or not, it probably wouldn't be too bad.

What Yang Yu didn't expect was that this feather could be used as a weapon.

But this is too small, right?

With a two-inch long weapon, the only way he could think of was to shoot it out. The feathers just happened to have blood poison on them, and maybe they could kill the enemy with blood.

I just don’t know if this thing can be recovered after being shot out.

Thinking of this, Eucalyptus poplar put it on the feathers to purify them, and planned to give it a try.

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

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

"Hiss——"

The next second, Yang Yu straightened up on the spot and took a breath of cold air!

The feeling of the feathers being pulled out was like the spine being pulled out from his body. Although the pain was not painful, it was very sore, and a pulling sensation went straight from the Tianling Gai to the tail vertebrae.

Until the sour feeling passed, what surprised him was that as the feathers were pulled out, a large number of red tendons were pulled out from the position where the feathers grew out. The tendons were entangled together for a long time.

Two fingers thick.

The tendons connected his body on one side and the tail ends of the feathers on the other. The bright red blood visible to the naked eye flowed rapidly in the tendons, and the feathers in his hands also quickly grew in size in an instant.

With just one breath, the feathers that were originally only two inches long suddenly expanded to more than one meter long.

And the feathers that he could hold with just two fingers just now have grown so big that he can just hold them with one hand, like the handle of a weapon.

Looking at the enlarged spinal cord feather in his hand, Yang Yu finally understood what the information box said 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 to his surprise, it felt like holding a sword or a knife in his hand.

The blood transfusion veins that were pulled out of his body and connected to the feathers seemed to be unable to be disconnected and could only remain connected.

This feeling is a little weird, as if what he is holding is not a feather, but a part of his own flesh and blood organs, and he can feel the most realistic touch.

Swish, swish, swish!

Ding ding ding!

Yang Gu held the spinal cord feathers in his hand and waved them a few times, then flicked the left and right feathers with his fingers.

The red and white feathers exude a metallic sheen, and even the sound sounds like metal. The texture is hard, and each individual feather looks very sharp.

However, this thing feels like an ordinary sword to him, and its hardness should only be at a very ordinary level, which cannot be compared with a magical weapon.

Perhaps this is related to the infancy stage described in the information box. The hardness of feathers has not reached a higher level and can only be used as ordinary weapons. They need to be irrigated by blood to grow.

Yang Gu glanced left and right at the spinal cord feather in his hand, and the two colors, one red and one white, formed a sharp contrast.

The blood poison on Hong Yu cannot be tested for the time being, but he wants to try Bai Yu's attack method.

The next second, he thought.

Phew——

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

This chapter is not over yet, please click on the next page to continue reading!

But five meters away from him, Bai Yu suddenly stopped, just stuck in mid-air, unable to move forward.

At this time, Eucalyptus Yang saw that at the end of each white feather, there was actually a red line as small as a capillary connected, and the other end was connected to the rachis of the spinal cord feather.

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

Beyond this distance, the red line will straighten and become restricted, making it impossible to move forward.

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

Everything you want can be reached instantly and is extremely flexible.

This is Bai Yu’s attack method!

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

Yang Yu quickly came to such a conclusion.

Judging from this, even if Hong Yu has not tried it, I am afraid that the blood poison in it will not be too strong and still needs to grow.

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

The tendons connected to the feather roots are like a resilient elastic rope. When the spinal cord feather is held close to Eucalyptus poplar's waist, the tendons quickly retract into Eucalyptus poplar's body.

"Hiss——"

Eucalyptus poplar immediately felt a burst of sourness, rising from the tailbone to the sky.

As the tendons retracted into his body, the true feathers of the spinal cord also continued to shrink and become smaller. In the blink of an eye, they shrank back to their original length of two inches and returned to Yang Gu's lower back.

Once his clothes were on him, no one would have thought that there was a large or small weapon hidden on his lower back.

Regarding the harvest from this apprenticeship banquet, if you exclude the feeling of eating those things, then he must be very happy.
