Disciple, you are invincible, go down the mountain and harm your fiancée.

The door of the twelfth floor of the Yin-Yang Tower was completely open, and Li Daofeng stepped in quickly with excitement.

The scene that appeared in front of him was exactly the same as before. In the middle of the empty palace, there was a very simple table, and on the table, there was a box.

However, the box this time was different from the previous boxes on each floor of the Yin-Yang Tower. The previous boxes were all square, but the box in front of him was a rectangular box.

"It's different. It's finally different. Could it be that there is some good treasure?" Li Daofeng looked at the black rectangular box in front of him and felt more expectant in his heart.

Li Daofeng immediately opened the box. The moment the box was opened, Li Daofeng felt a powerful aura rushing towards him.

Immediately afterwards, a cyan dragon's shadow rose into the sky from the box, and disappeared in the tower.

The sound of dragon roars resounded in the box. The sound was so loud that it made Li Daofeng's ears hurt.

"What the hell...what's going on?"

Li Daofeng had never encountered this kind of situation before, and he was a little confused when it happened suddenly.

After all the strange phenomena disappeared, Li Daofeng saw that inside the box, there was a bone like a spine, which was thirty or forty centimeters long.

Judging from the shape and size, it does not look like a human spine, but rather like the spine of some ferocious beast.

There is a domineering aura on the spine! It gives people an inexplicable sense of coercion.

Facing this half of the spine, Li Daofeng actually felt an inexplicable sense of oppression in his heart, just like when a lower-ranking person sees a higher-ranking person, he feels a sense of awe in his heart.

Li Daofeng held his breath, then reached out and picked up the spine from the box.

However, the moment his hand touched the spine, a piece of news appeared in his mind.

"Dragon Veins! Transformed into the Azure Dragon, the divine beast of heaven and earth!"

Just these few words! Nothing else.

But just these few words shocked Li Daofeng's heart.

Dragon Veins! Qinglong!

Li Daofeng felt that his three views had been directly subverted! A mythical beast like Qinglong actually exists, and there is actually a dragon vein in front of him. Who would believe it if he told it like this?

But the facts were right in front of him, and he really felt the powerful aura from this dragon vein!

He had half of the dragon's spine on his body, and he knew how powerful the aura on it was, but that half of the dragon's spine was nothing compared to this dragon's veins.

"Is this thing real? Should it be used? Is it also used as a weapon?" Li Daofeng looked at the dragon vein in his hand, and for a moment he didn't know what the dragon vein was used for.

If it was a magic weapon, even if it was a piece of fruit, he would still know how to use it.

But to put it bluntly, this dragon vein is just half a bone. how to use?

It was considered a weapon that was incompetent, and there were no martial arts secrets on it, so it was even more impossible to eat it.

This really stumped him!

"Can it be used to make elixirs?" Li Daofeng thought of another way.

However, just when he was thinking about whether he should try now to see if this dragon vein could be used to make elixirs, another piece of information came into his mind.

"Refining the dragon's veins, blending them into one's own body, and obtaining its destiny!"

"I rely on!"

Seeing these twelve words, Li Daofeng couldn't hold back the curse words.

"Refining and melting into oneself. What the hell are you kidding me? How can such a big bone be melted into oneself? I'm not sure whether it's a dragon vein or not, let's just refine it! After saying that even if it's a dragon vein or a dragon bone, I can’t refine it and blend it into myself!”

"If I refine this thing into myself, what kind of monster will I become? I already have half of the dragon's spine on my body. That half of the dragon's spine now makes me look like a mutant!"

"Although the mutation is in place and very powerful, it is not normal. If I refine and fuse this dragon vein, what will I become? Who knows!"

Li Daofeng refused in his heart! Look at the dragon vein in your hand! He hesitated.

After thinking about it, he finally decided to refine the dragon vein according to the information in his mind, blend it with himself, and see what blessings he could get.

after all! He believes that the things in the Yin-Yang Tower will not harm him. If they wanted to harm him, he would have died 1,800 times ago. Why not die now? There is no conspiracy to fatten him up and kill him, right? .

After figuring it out, Li Daofeng felt that there was nothing wrong! Moreover, it allowed him to refine it and blend it into himself, unlike before when his old pervert master saved him and directly installed a dragon spine on him.

This is just like eating meat. One is eaten directly, and the other is eaten cooked. You may not be able to stomach raw meat, but if you eat cooked meat, it will definitely taste super delicious.

After figuring it out, Li Daofeng started refining directly according to the refining method!

As his blood drips on the dragon's veins, internal force is used to promote the refining of the dragon's veins.

After a while, Li Daofeng discovered that the dragon veins began to melt rapidly into a stream of air and entered his body.

The moment the air flow formed by the dragon vein entered his body, Li Daofeng felt that his body almost exploded.

"Fuck..."

Li Daofeng swore directly, and then cold sweat broke out on his forehead.

He felt like this breath was pouring into his body like knives, giving him the feeling that every part of his body was being torn apart.

And this breath, after entering his body, rushed through his body, as if it was trying to break through his body.

At this moment, Li Daofeng felt that his seven meridians and eight meridians, even his flesh and blood, were being torn apart crazily.

The severe pain made him doubt his life.

He has always felt that he is a very tolerant person. He grits his teeth and gets over the ordinary pain, thinking it is not a big deal.

But this time! He really felt like he couldn't bear it anymore! This kind of pain was beyond his imagination!

In a short period of time, Li Daofeng's whole body was soaked with cold sweat! He gritted his teeth and persisted! Enduring the huge pain, he performed the exercises and guided the movement of the breath.

But he discovered that this aura was like a wild horse that was running wild and was not under his control at all. No matter what method he used, this aura was out of his control and was still running rampant and tearing through his body. Every part of his body.

"what……"

In the end, Li Daofeng couldn't help the heartbreaking pain, roared, and slammed his fist on the ground.

A powerful force instantly burst out from his fist.

boom! ! !

The entire Yin Yang Tower seemed to be shaking! With Li Daofeng's fist as the center, the energy spreads out and sweeps across wherever it goes! The whole space was shaken.
