…

Phew~~~~

After a few breaths.

Lin Zheyu slowly opened his eyes, and the confusion in his eyes flashed away.

He shook his head and looked at the dim world around him, feeling a little dazed for a moment.

"This feeling is really strange..."

Lin Zheyu had a strange feeling in his heart as he recalled the process of using his source power to practice the "Dream Heart Technique".

Under the erosion of the power of nightmare, his whole person fell into a nightmare.

At first, I was able to stay awake.

But as time went by, I gradually lost myself.

Fortunately, even if this technique loses Lin Zheyu's control, it can still operate on its own under the constraints of the martial arts divine patterns.

"Although the effect is average, it is much faster than doing nothing and relying on your own slow adaptation."

Lin Zheyu felt the condition of his body, and his resistance to the power of nightmares had been greatly improved.

Just using one unit of source power exceeded the resistance to the power of nightmare that I had gained after entering this wonderful scene for so long.

Not just that.

Lin Zheyu could also feel that his physical body, soul and spirit had also improved a lot, and even his spiritual eyes seemed to have undergone subtle changes.

"continue……"

Soon, Lin Zheyu started the second round of training.

Because when practicing, he would fall into sleep uncontrollably due to the erosion of the power of nightmares.

Therefore, he did not accumulate much cultivation experience and insights.

Even if Lin Zheyu wanted to further optimize and perfect the technique, it would be difficult for him to do so for the time being.

He can only wait for when he can resist the erosion of the power of nightmares and practice this technique while staying awake.

Only then can we accumulate enough experience and insights to carry out subsequent optimization and perfection of the exercises.

Time passes slowly...

One unit of source power is consumed.

Lin Zheyu's ability to withstand the power of nightmares increased at an alarming rate.

At the beginning, he did not dare to swallow too much energy as the source of energy for Yuanli cultivation. When using Yuanli for cultivation, he also needed to consume a large amount of clones as the energy source for Yuanli cultivation.

As time passed, Lin Zheyu's ability to withstand the power of nightmares increased, and the ratio between the two gradually decreased.

Two days later, Lin Zheyu was able to withstand the majestic power of nightmare contained in the energy consumed by using one unit of source power.

Three days later, the concentration of nightmare power outside Nightmare City could no longer meet his training needs.

At the same time, when he practiced, he stayed awake longer and longer.

Lin Zheyu was finally able to make "Big Dream Mind Technique" more perfect and powerful through iteration and optimization.

In the blink of an eye, more than a month and nearly two months have passed...

Wow~~~~

In the city of nightmares, the gray river is surging.

puff--

Suddenly, a burly figure jumped out of the gray river.

"It's time to go back..."

Lin Zheyu murmured secretly.

He glanced at the data in his consciousness.

After repeated optimization iterations, he has perfected the "Big Dream Mind Method" to its second level.

Nearly two months have passed, and he has spent more than 90,000 units of source power, and successfully cultivated the "Dream Heart Technique" to the second level of perfection.

This is already the limit that Lin Zheyu can reach.

"Now, even the astonishing concentration of nightmare power contained in this long gray river cannot affect me."

Lin Zheyu looked back at the rushing gray river.

Now, he is completely immune to the high concentration of nightmare power contained in the long gray river.

To Lin Zheyu, this long gray river was just an ordinary, gray river.

After cultivating the "Great Dream Heart Technique" to perfection, his ability to withstand the power of nightmares has reached an astonishing level.

When coming out of the long river rushing next to him, Lin Zheyu deliberately swallowed the vast energy contained in the long river and stored it in the void of the inner universe for later use.

Under the erosion of such astonishing nightmare power, he still felt nothing.

…

"Going in!"

Chang Zichen, who was hiding in the formation flag, suddenly stopped what he was doing.

Sensing the abnormality of his senior brother, Mu Yunshi also stopped.

She followed Chang Zichen's gaze and found that the burly man was beginning to try to break the formation restrictions at the entrance of the cave.

"Are we finally going in..."

Mu Yunshi looked at Chang Zichen: "Senior brother, do you think he can succeed?"

"It's hard to say."

"According to records, the most difficult thing about this place is not the formation restriction, but the extremely pure power of nightmare in the cave."

"That place is most likely the retreat of a strong man from the nightmare tribe. It is filled with an astonishing concentration of pure nightmare power."

"As long as you step into it, you will be eroded by the power of nightmares and fall into sleep uncontrollably."

Chang Zichen looked solemn.

Even with the means he had prepared in advance, he was not very sure that he could withstand the erosion of the pure power of nightmares in the cave.

However, no matter what, you have to give it a try.

Before entering the setting sun of the era, Chang Zichen and Mu Yunshi focused on preparing many methods for the dozen of wonders inside.

Among the dozens of wonders that have been carefully prepared, there is the wonder of Nightmare City.

The power of nightmare is an extremely powerful and mysterious force, which was the foundation of the original strength of the nightmare tribe.

Even many realm lord level experts would be jealous of the Nightmare Clan's cultivation techniques.

It can be said that the wonders of the Nightmare City are one of the wonders that almost every force that knows about this wonders will make adequate preparations for before entering the setting sun of the era.

However, not everyone can enter this wonderful scene.

Only true geniuses and monks with amazing talents can enter this wonderful scene.

"If you fail, you fail."

Mu Yun's poems are indifferent to Tao.

She didn't really care about Lin Zheyu's success.

In other words, Mu Yunshi originally did not have high hopes for Lin Zheyu's success.

Mu Yunshi's attitude has always been that it would be best if the other party can succeed, and all he has to do is seize the opportunity from the other party.

However, it doesn't matter if it doesn't work. If the other party fails, they will go deep into it and explore it themselves.

Before entering the setting sun of the era, they had prepared many means. Mu Yunshi was still quite confident in dealing with the strange scene in the Nightmare City.

…

Time passes slowly...

More than two months have passed...

Lin Zheyu left the formation as usual.

However, after leaving, he did not go outside the Nightmare City, where the power of nightmares was weak, to restore his condition.

Now, Lin Zheyu's ability to withstand the power of nightmares has reached an astonishing level, and he no longer needs to leave to find a place to refine the power of nightmares in his body.

As long as the concentration of the power of nightmare is not too terrifying, then to him, the power of nightmare will be as sparse and ordinary as air and water, and it will not have much impact on him at all.

…

Lin Zheyu left the area restricted by the formation, walked around in a circle and came back again.

He quietly hid in an area not far from Chang Zichen and Mu Yunshi.
