After choosing the exercises, Ning Tian began to cultivate.

However, as soon as he was about to cultivate, Ning Tian found a very embarrassing problem, that is, it seemed that he couldn't move his legs now! The medical machinery that tied his legs was treating the muscles and tendons of his legs, and this long-term process seemed to be ineffective, otherwise it would have no effect. But it seems that this means that you can't meditate cross-legged, and if you can't meditate, then you can't start exercising the internal force of the Dharma meridians.

Ning Tian was lying on the bed, a little wanting to laugh.

This is the first time in his 30 years of cultivation and rebirth, and the first time that he has not been able to practice because he can't meditate, which really makes people smile a little bitterly.

However, Ning Tian still sat up, turned on the knob of the instrument that specializes in treating leg bones, and took the machine away from his leg.

Since it has been said that the treatment cycle of this technology is one month, it is better to go your own way.

Pull your legs out of the healing apparatus, cross your legs, and meditate.

In the dark night, on the hospital bed, the moon is shining outside the floor-to-ceiling window.

Ning Tian began to cultivate.

The first is to mobilize the internal force in the dantian in the body, and follow the meridian running route of the Jiuyang Shengtiangong to walk through the whole body. This is called marrow opening.

Sink your mind into the dantian, hold your breath and concentrate, mobilize the internal force in your body and start running along the meridians. Under the traction of Ning Tian's spiritual power, the internal force began to swim along the specific meridians, and it was not smooth along the way, on the contrary, because it was the first meridian marrow opening, which made the operation of the internal force several times resisted. Some meridians themselves are not among the five meridians and eight veins, and even the side branches of the left door, which are themselves narrow, and it is even more difficult to smooth the internal force.

Ning Tian had to grit his teeth and persevere, constantly condensing his mind to let the internal force impact, and constantly enduring the swelling pain and tearing feeling of the meridians being forcibly stretched.

One by one, step by step.

This is a very mind-consuming practice, not to mention that as the top exercise of the heavenly level, the Jiuyang Holy Heavenly Gong is not only a few hundred running meridians, but a complex network of tens of thousands of circulating meridians, tens of thousands of meridians have to be run through all with internal force, how huge the amount of work is, and how huge the mind is consumed.

In addition to this, it is not allowed to take a break during the marrow opening period, even if you have successfully opened up 9,999 meridians, only one is missing, if you can't hold it and let your mind withdraw from it and rest, it means that all your efforts have been lost.

The Heavenly Rank exercises have already reduced more than half of the people from the starting point. It doesn't mean that having the Heavenly Rank Exercises means that you can have the ability to cultivate them, but also that you must have a superb understanding and mind. Needless to say, the nature of the mind refers to whether you can endure the pain of opening the marrow of the meridians, and whether you can concentrate your mind from beginning to end.

This is how cultivation goes on step by step, and there are no shortcuts.

One minute, two minutes...... Time passed quickly for Ning Tian, who was mentally focused.

His forehead was already covered with beads of sweat at some point, some of them because of the pain of opening the marrow of the meridians, and some of them were hot sweat from his preoccupation.

A thousand ...... 2,000 ...... 3,000 ......

Ning Tian's powerful spiritual power played an important role at this time, otherwise just memorizing the trajectory of these meridians would be intimidating for ordinary martial artists, and the powerful spiritual power accurately and solidly led the internal force to run in this complex meridian network.

4,000 ...... 5,000 ...... 6,000 ......

Reaching this stage of opening the marrow of the Jiuyang Saint Heavenly Gong, Ning Tian had already decided that his spirit was a little swollen, and his mind began to be tired.

7,000 ...... 8,000 ...... 9,000 ......

The obvious feeling of dizziness hit, Ning Tian encountered unprecedented resistance in the process of running the internal force to open the marrow, and at the beginning, the soaring progress has also become the current step by step, there are thousands of branches in this complex meridian network to distract your attention, only with a high degree of investment can you find the correct route of Jiuyang Shengtiangong in it.

Nine thousand nine hundred...... Nine thousand nine hundred and ninety-ninety...... Nine thousand nine hundred and ninety-nine ......

Ning Tian's spiritual power was almost exhausted, and what was more worrying than this crisis of spiritual power was Ning Tian's body, I don't know when Ning Tian's body began to tremble violently, this trembling was not a simple shaking of limbs driving the whole body.

This kind of trembling should be called convulsions, the convulsions of the whole body, every muscle and tendon are twitching violently, as if Ning Tian's entire body is about to fall apart. If you lifted his clothes, you could see that Ning Tian's whole body was already blood-red at the moment, not because he was cut, but because his blood was boiling! Nearly 10,000 meridians had been refined into a line, and at this moment, it was like a thousand shots almost collapsing!

If Ning Tian couldn't open this last meridian to penetrate the ten thousand meridians, then what was waiting for him would probably be that the meridians would be broken, and he would go mad and vomit blood.

If you don't advance, you will die, and if you are wrong, you will die!

It's a dead end that has never been chosen from the start.

Ning Tian's face looked like it had been fished out of a pool of hot water, and beads of sweat slid down his chin and almost soaked the clothes on his chest.

Gritting his teeth, Ning Tian forced himself to concentrate his mental power and find the last one among the thousands of meridians!

One minute...... Two minutes......

Time passed quickly in the outside world, but for Ning Tian, who was stuck in the last marrow opening meridian, every second was as long as a century, and he couldn't describe his torment like sitting on pins and needles.

But in this dilemma, although his mental strength can barely support it, his body is almost collapsing!

After feeling the tendency of his body to almost disintegrate, Ning Tian's two rows of teeth almost bit out blood!

Blood from the gums flowed down the corners of his mouth, staining the white sheets red!

Which one?Choose!Ah!!!hh

Finally, under the extreme pressure, Ning Tian's originally exhausted spiritual power suddenly emitted a divine light!

In less than a second, Ning Tian only felt that his thoughts were incomparably clear, and his spiritual power was incomparably full!

At that moment, Ning Tian felt an unprecedented strength, a powerful spiritual power!

In front of this powerful spiritual power, the last meridian was easily found by him, and the inner force of the leader wandered into it!

So the opening of the 10,000 meridians of Jiuyang Shengtiangong was finally completed!

But before Ning Tian had time to check the changes in the internal force in the dantian, a huge feeling of exhaustion in his body hit, and at the same time, the originally full and empty spiritual power seemed to lose its effectiveness after that moment, and all of a sudden the spiritual power was completely drained, and Ning Tian could only feel that his consciousness was black and he could no longer think otherwise.

Ning Tian was so tired that he was on the hospital bed, and outside the floor-to-ceiling window, the moon had set, and there was some light on the horizon of the sky.

The old pendulum clock hanging in the room was pointing to the five o'clock tick in the morning......
