Du Hei's steps became heavier and heavier.

This heaviness is brought by the body, but it is not brought by the body.

The blood and muscles all over his body didn't feel anything, except that the meridians flowing with spiritual power were tingling.

The core of the profession swirls and explodes.

If it was in normal times, Du Hei would be filled with spiritual power all over his body in an instant.

But now, this spiritual power only flows in the body, and cannot overflow the surface of the body.

And didn't step out of the first floor.

He would find that there seemed to be an invisible membrane on top of the staircase, and it required an explosion of spiritual power to pass through.

With the power of the flesh alone, there is no way to pass.

However, fortunately, when Du Hei was on the fiftieth floor, he got used to it for a long time.

Therefore, although this feeling is not very comfortable, it is not stagnant.

Soon, on the seventieth floor, there were three people here, each at some distance, sitting cross-legged.

Obviously, these three people should not be able to continue to rise in a short period of time.

Duhie stepped through the gap between the three of them.

Continue upwards.

He felt that his spiritual power was much more refined than before.

"Hundred layers. ”

Du Hei looked up, his gaze resolute.

At this moment, Du Hei could no longer see the figure of Tu Shan.

Obviously, the other party has already exceeded the distance of dozens of layers of his own in the case of frog jumping.

Du Hei's face was as usual.

Continue upwards.

At the hundredth floor, Du Hei felt that his spiritual power was flowing extremely slowly.

And in this state of stagnation, if you urge the core of the profession, what will be the result?

That is, the meridians are subjected to a major test.

The core of the profession is like a faucet, and the meridians are like water pipes.

In itself, spiritual power is the flow of water, flowing freely in the water pipe, and the meridians will not be under the slightest pressure.

But as the pressure increased, these spiritual powers, which were originally like a stream of water, turned into viscous glue at the moment, and it was difficult to move.

And the faucet suddenly unscrewed, trying to wash away the glue in front of it and form a running water again, naturally, there will be a momentary delay.

And this delay will make the meridians like water pipes be greatly tested.

However, this result is still within the acceptable range of Du Hei.

It's just that it is enough to imagine that if you continue to go upward, when the spiritual power is close to stagnation, these glues will turn into silt.

At that time, maybe the meridians will directly support until they explode, and they will not be able to make the spiritual power flow around the body.

Spiritual power cannot flow around the body, and naturally, there is no way to continue upward.

However, all this is not in Du Hei's consideration for the time being.

"Luckily, there's still a lot of time. ”

Du Hei's heart is still relatively relaxed.

He only meditated for forty minutes on the 50th floor, and it took about 20 minutes to walk all the way to the 100th floor, which was only half an hour in total.

And the hundred floors, the time you can stay is two hours.

In other words, he could at least meditate here for an hour and a half.

Sit down cross-legged again.

The clock is ticking.

However, this time, it is obviously due to the time and the higher number of layers, which makes it more difficult to adjust and adapt.

As a result, Du Hei did not reach the same state as he did when he was on the 50th floor.

This is not surprising.

After all, if every time you reach a level, you can quickly adapt to the cultivation, then wouldn't everyone be able to go up to a few hundred levels?

The further you go to the rear, the more difficult it is to adapt and the harder it is to improve.

After all, the path of cultivation is already even more difficult.

When the spiritual power is refined to a certain level, it is extremely difficult to improve every step.

This is the same as origami, a piece of paper, easy to fold in half, three folds simple, but eight folds and nine folds are more powerful than one time, when the limit is reached, it is the time to break through.

Didn't dare to stay any longer.

Duhei continued upwards.

This time, on the one hundred and twentieth floor, Du Hei's footsteps stopped.

He felt that his spiritual power seemed to be almost stagnant.

There was no way to lift the spiritual power at all, and the invisible film that stopped in front of the next ladder was crushed.

Squinted slightly.

Du Hei knows that this should be his limit at the moment.

The degree of essence of spiritual power, as well as the degree of meridians, can only support him here.

But fortunately, there is still a long way to go.

Du Hei simply sat down and slowly urged the professional core again.

At this point, Du Hei didn't dare to forcibly let the spiritual power explode, otherwise the meridians were likely to be broken.

Stagnation again.

Time flows.

One hundred floors up, Duhei can stay for four hours.

Except for the time before, in fact, what could be provided for his cultivation was less than two hours.

An hour passed, and the spiritual power could barely function.

Du Hei stood up at this time.

Take a deep breath.

His eyes were glued to the steps in front of him.

The steps, which were not enough to be taken seriously, are now like a moat.

"All it takes is a trace of spiritual power to burst out, and you can step through this layer!"

Du Hei muttered in his heart.

The core of the profession, at this moment, turns again.

A steady stream of new spiritual power is flourishing.

From the core, flowing out, but at the same time, it is slow progress.

Finally, Du Hei felt that he was very close to stepping out of this layer.

But again, his meridians were a little overwhelmed and painful.

"Over!"

A low roar.

A trace of spiritual power finally escaped from the surface of the body, successfully shattering the membrane, and Du Hei also stepped on the one hundred and twenty-first layer.

But.

That's when it happened.

Du Hei felt a tingling pain in his abdomen.

The meridians, at this moment, cracks appeared.

Du Hei's face sank.

But soon, his face was stunned again.

After the strengthened body, after consuming a little spiritual power, it actually repaired the slightly shattered spiritual power.

The repaired part has become thicker and wider.

Du Hei's eyes lit up at this time.

Suddenly, he felt.

Seem......

Can you do this yourself?

If the meridians are wide enough, then even if the spiritual power is suppressed, it is impossible to be unable to circulate.

And he can unscrupulously urge the professional core to break out, in order to step on a higher level.

Even, even later, when the spiritual power can't move completely, he can keep impacting, as long as the pressure is strong enough, he can force the spiritual power to urge.

"Maybe, really. ”

Du Hei muttered, and a hint of fierceness flashed in his eyes.

He knew what he meant by the way he thought of it.

It means suffering, it means, the pain is unbearable.

But if he succeeds, the essence of his spiritual power may reach a level of invincibility of the same level.

Even, like spiritual power, directly exceeded the upper limit of the essence that should be at this stage.
