In the Qi and Blood Pool, as Zhang Xiaoyu began to cultivate, the originally calm Qi and Blood Pool was also flooded with some ripples at this moment.

At first glance, it looks like a stone thrown into a calm lake, and the ripples are constantly spreading outward.

Zhang Xiaoyu's eyes were closed, his spirit and spirit were united at this moment, and the whole person had entered a state of self-forgetfulness.

Outside the qi and blood pool, Zhang Shanfeng's eyes flashed slightly, and he didn't know what he was thinking.

Because of the fact that the vertebrae were not tempered, Zhang Xiaoyu was also cautious about this breakthrough.

In the beginning, the power of qi and blood absorbed was very small.

With the integration of the power of qi and blood, Zhang Xiaoyu's bones also turned a blood-red.

The bones of Ruyu have completely turned into a blood jade color at this moment, and the golden silk threads inside the bones are flickering slightly at this moment, looking extremely weird.

The first absorption lasted about an hour, and when all the bones of his limbs turned into blood and jade, Zhang Xiaoyu began to guide the power of qi and blood to refine the bones of the torso.

In the cultivation of the martial apprentice period, what is tempered is the bones of the limbs.

And the cultivation of the warrior realm is tempered by the torso bones.

These two parts, in fact, are independently refined and have not been connected.

It's like two different rivers, flowing separately and not affecting each other.

What Zhang Xiaoyu has to do is to let these two rivers come together to form a more powerful flow, and when this process is completed, it will be equivalent to Zhang Xiaoyu and successfully enter the realm of war generals.

Soon, two hours passed again.

In the trunk bones, except for the spine, the other bones also turned a blood-colored color.

Zhang Xiaoyu let out a long breath, stabilized his mind, and began to try to penetrate the barrier between the upper limb bones and shoulder blades.

The power of qi and blood slowly converged at the intersection of the two bones, and formed a vessel-like pattern.

As more and more qi and blood power gathered, at the junction of the bones, the two bones began to make a crackling sound as if they were about to merge together.

There are two places in total for the convergence of the bones of the upper limbs.

Soon, the connection between the upper limb bones and the shoulder blades was completed.

At the moment when the breakthrough was completed, a crisp explosion erupted in Zhang Xiaoyu's body.

And the entire pool of qi and blood is also boiling.

A powerful force of qi and blood passed through the upper limb bones, injected into the upper part of the trunk bones, and finally stopped at the spine.

The pool of qi and blood returned to calm.

A touch of solemnity flashed in Zhang Shanfeng's eyes, and he muttered to himself: "I have completed the penetration of the upper limb bones so quickly, is this the advantage of perfect bone quenching?"

In the pool of qi and blood, Zhang Xiaoyu let out a sigh of relief.

Then, step by step, begin to penetrate the barrier between the lower limb bones and hip bones.

This breakthrough lasted about five hours.

When the two powerful qi and blood converged and flowed through the limbs and torso bones, Zhang Xiaoyu snorted, and his face instantly turned red.

In the pool of qi and blood, the red qi and blood were churning instantly.

In the body, the two fused qi and blood, like two fierce beasts, carrying an indomitable momentum, washed over the vertebrae again and again.

Bursts of explosions sounded in Zhang Xiaoyu's body from time to time.

The strong fluctuation of qi and blood made his vertebrae a little unbearable, and he kept making clicking sounds, as if he would break at any time.

When a warrior enters the realm of war generals and completes the penetration of the limb bones and torso bones, he is not considered to have truly entered the realm of war generals.

At this time, although the limb bones and trunk bones are connected, the vertebrae are still independent.

The spinal cord is the source of qi and blood in the human body, and it is also one of the most important bones in the human body.

The spinal cord contains the necessary hematopoietic stem cells for the body.

Warriors are also human beings, and the generation of the power of qi and blood also depends on cells.

The ultimate goal of martial arts cultivation is to complete the evolution of cells and genes.

In a sense, the more powerful hematopoietic stem cells evolve to, the faster they can recover qi and blood.

It's like two rivers coming together, but the source is still not connected.

What Zhang Xiaoyu has to do is to use the power of qi and blood to penetrate the barrier between the limb bones, trunk bones and spine.

In the body, the four strands of qi and blood gathered from the bones of the limbs constantly hit the spine.

Zhang Xiaoyu's face was pale, and he couldn't care about the pain for a long time.

At this time, the slightest mistake may lead to the fragmentation of the spine, and thus enter the legendary state of hemiplegia, or even full-body failure.

Without thinking too much, Zhang Xiaoyu stabilized his mind, hurriedly controlled these qi and blood powers, and began to penetrate the barrier.

An hour passed, and there was no penetration.

Two hours passed, and there was still no response.

......

Five hours later, Zhang Xiaoyu panicked.

More and more qi and blood are converging in the body, and the barrier between the limbs, torso and spine still shows no signs of penetration.

And because he was in the qi and blood pool, the speed at which the qi and blood in his body converged faster and faster.

"What to do, what to do, if it is not penetrated, I don't know what will happen to the source, and the tributaries are going to flood. ”

Zhang Xiaoyu felt bitter in his heart.

This situation was also something he didn't expect.

At this moment, his situation is like a river, suddenly too many water sources are flowing, and these water sources are not dredged and flowing in time, and the final result is that the river embankment bursts, resulting in flooding.

Rivers flood and affect the surrounding land.

And once the power of qi and blood cannot be controlled, Zhang Xiaoyu's body is likely to collapse directly.

The human body is based on bones and supplemented by flesh and blood.

Once the flesh and blood collapse, with Zhang Xiaoyu's current cultivation, he will definitely die.

Although a warrior has the ability to recover, it is also based on the premise that the injury can be recovered.

The body collapsed, and now Zhang Xiaoyu can only wait for death.

Outside the Qi and Blood Pool, Zhang Shanfeng obviously also discovered this.

"What is this kid doing, it's been a few hours, so it's not through, what's wrong?"

muttered, Zhang Shanfeng did not make a move, but the look of anxiety in his eyes became more and more obvious.

As a powerhouse in the War Emperor Realm, he is naturally no stranger to martial arts cultivation.

Zhang Xiaoyu's situation, he really saw it for the first time.

Time, again, an hour passed.

through, still not the slightest progress.

And the power of qi and blood in the body has gathered to an extremely terrifying point.

If it is not penetrated, Zhang Xiaoyu is likely to explode and die.

"Boy, what are you doing, hurry up and break through the barrier between the vertebrae and other bones, and keep playing, don't play yourself to death. ”

Zhang Shanfeng stood up and whispered.

Although he is in cultivation, Zhang Xiaoyu can also hear the words of the outside world.

He was full of helplessness and despair at the moment.

Do you think I don't want to get through?

I can't be good or bad.

At this time, there are no more than two choices.

The first is to give up the advanced level and forcibly break the barrier between the limb bones and the trunk bones, and the gathered qi and blood power will naturally disappear.

The second is to forcibly quench the vertebrae and then try to penetrate them.
