"I don't know what's in the dungeon?"

With such curiosity, Lin Feng immediately stepped into the corridor.

The corridor was quite dark, but Lin Feng had prepared torches in advance, and it was not a big problem.

In this way, Lin Feng walked down slowly for a while, and only then did a huge grotto suddenly open up in front of him.

It can be seen that this so-called Xiaoyao underground palace is built according to the natural cave in the belly of the mountain.

"What a big deal!" In this world where all means are banned, opening up such an underground palace is afraid that only the lord of Sumeru Golden Mountain can do it!" Standing in front of the grotto gate, Lin Feng sighed greatly.

Wow -

Slowly pushing open the stone door, after seeing the scene in the underground palace, Lin Feng was stunned.

In other words, extremely confused!

The reason is simple, the dungeon is empty and there is nothing left!

There is a huge underground palace, and there is nothing but a stone pillar in the center and a polished rock with very smooth walls.

The stone wall is carved with countless circles with diameters and feet, and various figures are carved in each circle.

Some are human figures, some are beast-shaped, some are incomplete words, and some are just marks and lines......

In short, there are more than a thousand circles.

"What are these things?" Lin Feng, who was deeply curious, randomly found a circle and looked at it fixedly.

Buzz, buzz.

As soon as he stared at it, Lin Feng felt an invisible impact of will, and he was confused, his body shook, and he fell to the ground.

Fortunately, in the past few months, his psychic power has improved rapidly, and he has a basic ability to resist the impact of will.

Otherwise, the previous violent will impact could make him delirious and stupid, or it could directly kill him!

"What a terrible will impact!" Lin Feng, who had palpitations, didn't dare to look at any of the circles anymore, and lowered his head and muttered, "In the underground palace, what kind of heart cultivation method is there?

"Could it be that, like the canyon in Ruins 18, I have to start with the simplest and weakest circle?"

As soon as he thought of this, Lin Feng immediately moved his gaze to the first circle.

Within this circle, there is only one point, which can be described as extremely simple!

............

Half a minute later.

"Sure enough!"

After staring at the first circle for a while, and feeling the invisible power revealed in it, Lin Feng's heart suddenly surged.

Because he found that the impact of the will contained in the first circle was completely withstandable for him!

At the same time, with the end of the will impact, he also faintly felt that his spiritual power had improved!

In other words, as long as he keeps looking at the first circle, his psychic power can grow rapidly!

"Here, this is simply a treasure place for cultivating mental strength!" The essence in his eyes was bright, and Lin Feng was excited.

He now finally understood why the Lord of Sumeru's Golden Mountain had deliberately set up a test before entering the Wandering Underground Palace.

The reason is very simple, a person who has not bred mental strength and nurtured mental strength to a certain extent, even if he comes to this Wandering Underground Palace, it is useless!

"It seems that there is a different degree of volitional impact in each circle. As long as I look at the suitable circle here for many years, my mental strength will be able to climb at a very fast speed! I don't know how many times faster than the improvement of practicing archery!" Lin Feng, who was more and more excited the more he thought about it, looked at the first circle again with excitement, ready to let his mental strength continue to grow.

"Cool, this kind of improvement is really cool!"

"The mental strength continues to improve, and breaking the ban is just around the corner!"

"We humans are saved!"

............

In this way, Lin Feng stayed in the underground palace for a whole year.

In this year's time, Lin Feng can be said to be diligent to the extreme, cold and summer, day and night.

In order to break the ban as soon as possible, so as to return to the human world as soon as possible and suppress the Heavenly Spirit Clan, Lin Feng did not dare to delay for a day!

So, after long-term efforts, Lin Feng finally completed the observation of all the circles today!

This means that now he can look at any circle at will, and can withstand the most violent impact of will!

It also means that Lin Feng's mental strength has reached an outrageous level now!

Buzz, buzz.

Just as Lin Feng was accepting the impact of the will of the last circle and sharpening his mental strength, suddenly, the only stone pillar in the underground palace suddenly trembled.

Lin Feng immediately looked at it seriously, only to see rows of golden words condensed on the stone pillars.

It's Luo Xin's text!

"It must be left by the Lord of the Golden Mountain of Sumeru!" Lin Feng realized it immediately, and then stared at the stone pillar with his eyes, and at the same time was horrified in his heart, "Every word has a strong will and coercion! If it weren't for the fact that in the past year, my mental strength has grown by leaps and bounds and reached an extremely strong level, I am afraid that the coercion revealed by these words alone can make our hearts collapse!"

Just when Lin Feng sighed, all the golden words on the stone pillar had been condensed, shining in Lin Feng's eyes:

"How eternal?"

"Four words, become an immortal!"

"The so-called immortal path is the fearlessness of the heart!"

"Kill all the demons, the demons in the heart, the demons in the heart, all of them must be killed!"

"If you want to get the immortal way, you naturally have to kill the illusory and seek the true self!"

............

All these words are full of the coercion of the brilliant will.

After reading a few lines, Lin Feng already felt dizzy and unsustainable.

However, when Lin Feng finished reading the last eight words "Kill the Illusory and Seek the True Self", his heart suddenly jumped as if he had been touched.

"Kill the illusory, find the true self! Kill the illusory, find the true self......" he muttered the eight words, repeating them over and over again.

As he spoke, a strange sensation permeated his body.

The next moment, Lin Feng only felt as if he was immersed in some wonderful liquid, and his whole body was extremely comfortable.

And at the same time, his entire inner world bloomed with dazzling light......

Endless nine-colored brilliance rose to the sky, illuminating the netherworld and the sea of blood.

Nourished by this wonderful feeling, Lin Feng unconsciously closed his eyes......

Gradually, Lin Feng's whole body seemed to turn into glass, as if it were real and illusory, and bloomed with an incomparably holy light.

After that, he slowly levitated, still in the dungeon.

For a long time, after a long time......

"Huh?"

Lin Feng, who was suspended, suddenly opened his eyes, and then let out an angry shout: "Break it for me!"

At first glance, his eyes erupted with terrifying fluctuations of will!
