The Secret Art of Burning Blood is the secret art of the Immortal Realm.

The conditions of use are also extremely harsh, and you must be a person who refines the body to use it.

Ordinary martial artists could hardly withstand the power of the Blood-Burning Secret Technique.

While he improves your combat power, it will also increase the burden on your body, and ordinary people's bodies simply can't withstand such sudden strength.

Therefore, even if it is a martial artist refining the body, using this secret technique will come at the cost of life.

According to the description, there is no upper limit to the maximum increase of the Blood Burning Secret Technique, but among those who have cultivated so far, the upper limit of the increase that can be increased is five times.

No one has exceeded five times that number.

Someone once forcibly broke through five times, but the body turned into firewood, the blood turned into flames, and the entire body was burned alive by the Blood Burning Secret Technique.

Some talented people can increase their strength to three times, ordinary people can only reach four times, and top body refiners can withstand the oppression brought by five times their strength because of their physical strength.

The use of the Blood Burning Secret Technique is also very simple, injecting the true element into the blood, and then causing the true element in the blood to rub against the blood, and at the same time accelerate the flow of blood.

Treat the human body as a high compressor, frantically compress the power, and then explode.

The faster you go, the more power you can explode, but again, the greater the risk.

It's just that this is not a particularly dangerous thing for Xu Yang.

That Zhang Feng is a spear immortal, and he must have practiced his body since he was a child, so he can withstand four times the strength.

Xu Yang always felt that if this blood-burning secret technique was cultivated by the Great Demon, it would probably be much stronger than that of humans.

The body structure of the great demons is similar to that of humans, but the strength of their bodies is far greater than that of humans.

But this is also an idea, and Xu Yang doesn't plan to let any big demons learn.

The Secret Art of Burning Blood also requires proficiency, and the higher the proficiency, the stronger the power that can explode.

Zhang Feng has already cultivated to the point of entering the hall, but basically those who cultivate the Blood-Burning Secret Art will only come here.

Because in their opinion, whether or not the Blood Burning Secret Technique can be cultivated to the peak will not have much impact.

If the body can't bear it, it can't bear it, and it won't change depending on how proficient you are.

It can only be said that the limit of the body is there, even if the proficiency level is not much changed, the body can't bear the load, and it makes no sense to explode ten times the combat power and die in an instant.

It is recognized that cultivating to the point of entering the hall is enough to open up four times the strength.

It takes 10 million experience points to upgrade in the room, and Xu Yang is mentally prepared for the need for so many experience points to upgrade.

10 million experience points, Xu Yang didn't blink his eyes, and he upgraded to a slightly small stage.

After a little success, if you want to understand it, you need 30 million experience points.

At this point, he frowned and didn't go up.

"It's still time to be promoted to Yuanying first, the overall strength has gone up, and the effect of the increase is completely different."

Xu Yang lowered his head and muttered to himself, and then a faint blood-colored gas rose from his body.

There were all big demons around him, and they could see the changes in Xu Yang at a glance, and the aura of Xu Yang in front of them had obviously risen several grades, and a storm-like power was pouring out of his body.

"Double."

Xu Yang opened his mouth indifferently, then gritted his teeth, the corners of his mouth trembled, and the blood-colored gas around his body deepened and gradually formed a flame to wrap around his body.

The four big demons and the black crow all took a step back, and they felt the terrifying power of palpitations from Xu Yang's body.

"Double!"

Xu Yang frowned, his arrogance instantly turned crimson, and the speed of the rhythm became faster, like a steady stream of gas gushing out from the ground.

"Triple as much!"

At this time, the four big demons and the black crow retreated further, and they couldn't stand by Xu Yang's side.

Moreover, the burning blood-colored aura frantically devoured the surrounding aura, and the aura on several of their bodies had already been absorbed by the bronze pillar, and Xu Yang's side was like a bottomless pit, where did they dare to stand by Xu Yang's side.

"Quadruple!"

The blood-colored aura around Xu Yang gradually turned blue, like the center of a flame burning.

"Five!"

The blue color continued to deepen, and at this time, Xu Yang's facial expression also became very hideous, as if someone around him owed him millions.

"Judging from the strength of the Immortal Golden Body and the situation in which I have survived the Refining Body Thunder Tribulation, this state is almost at the limit."

Although Xu Yang's body is far stronger than all kinds of big demons, and even has the perverted supernatural power of the immortal golden body, it is still difficult to bear after using the blood-burning secret technique to reach five times.

But the only difference is that within three times, Xu Yang's outburst will not consume his own life force, and his physical strength alone can easily withstand it.

When it reached four times, the pressure began to increase all of a sudden, and the burning of the true yuan could no longer support it, and it began to have an impact on the body.

At five times, the life force began to be fully burned, and the speed at which the true element was used was also very terrifying.

In this state, Xu Yang guessed that even if it was his true amount, he could only hold up twenty moves at most.

"Sixth!"

Xu Yang almost gritted his teeth and shouted, at this time, Xu Yang's skin and flesh were visibly broken, but they were repaired under the endless force.

He gulped in a big gulp, like no amount of air could fill his lungs.

Xu Yang's state frightened the four big demons and the black crow, and his strength even caused a vibration in this small space.

"What the hell is this!"

King Boar shouted, "He's not going to destroy this space, is he?" Then we're all going to die! ”

"No, he won't survive if this place is ruined, he has no reason to destroy this place."

"I think he's trying some kind of secret art, and it's working!" Bai Wuchang was the calmest one, but despite this, in the face of such a powerful Xu Yang, he also took a deep breath.

At first, he didn't feel that there was much difference between himself and Xu Yang, it was just that Xu Yang had more means, and he just restrained him.

But in this way, Xu Yang did not use all his strength when he fought with him, and the gap between the two was like mud......

"Hoo ......"

Xu Yang let out a rough breath and returned to his original delicate appearance, the arrogance around him dissipated, his figure was obviously smaller, and his body was also wet with sweat.

Only then did the big demons dare to gather.

"Senior Xu Yang, you were ...... just now"

Xu Yang said indifferently: "The secret technique of burning blood, six times the strength, want to learn?" I'll teach you. ”

The four big demons waved their hands again and again, just looking at Xu Yang's appearance just now, they knew that this secret technique was not so easy to learn.

Here they carry chains and learn to fart.

"Sixfold...... In other words, it can increase your strength by six times in your normal state? Bai Wuchang finally understood what Xu Yang's number meant.

He swallowed his saliva, Xu Yang, who was six times stronger, didn't he directly reach the level of the top grid yuanying?
