Although it is said that the divine soul is composed of an invisible and substantial thought, it can fly to the sky, escape to the earth, and enter the sea without hindrance. But when it comes to implementation, there are many differences.

The soul is most comfortable in the air.

And when you enter the water, there will be a viscous resistance, and the further down you go, the greater the resistance.

Even if it is a ghost immortal, it can only dive to the depths of the sea at most, and it can't go any deeper.

And when you go underground, the resistance is even greater, more than ten times greater than in the water. When thoughts pass through the walls, they will consume a lot of divine soul power, let alone escape into the ground?

With Hong Yi's current cultivation, he estimated that he could only drill into a depth of hundreds or so at most, and he couldn't go any further. Otherwise, the power of the divine soul will be difficult to support, and it is likely that it will be trapped underground and will never be able to get out.

"There shouldn't be any underground palace or anything like that under the Great Zen Temple, and even if there is, it will definitely be discovered after so many years. However, the legends are not all groundless, since the monk jīng ninja said so, I still look for it. ”

After drilling into the ground for dozens of zhang, Hong Yi maximized his divine thoughts and tried his best to explore the surrounding situation.

It was gravel, dirt, and mud on all sides, and it was vast and muddy.

When Hong Yi was burrowing into the ground and wandering around, he found a lot of cellars and the like where things were hidden in the first few zhang depths, but there was nothing in the jīng light that had been looted.

Then, there are many underground rats, pangolins, hibernating pythons, and some bizarre, unnamed animals.

"I can only sense a radius of dozens of zhang underground, such a large area of the ruins of the Great Zen Temple, what kind of underground palace to look for, is it not looking for a needle in a haystack? No, I have to look for it with all my might. ”

After Hong Yi drilled into fifty or sixty zhang, he felt that it was difficult to wander, and it was particularly difficult to explore, just like a person, in the dark night, and there was no light, looking for a needle in a large number of houses, where to find it?

When the divine soul burrowed into the ground, the range of induction was greatly reduced, and it was really like a person exploring in the dark night, which made Hong Yi quite uncomfortable.

However, this was the first time that Hong Yi had used Dao techniques to explore the underground, and he felt that it was extremely novel. So he plans to use all his strength to explore again

"How is it, Hong Yi, have you found any clues?" Monk Jīng Ren Ren felt a sunny wind coming out of the rubble pile of the ruins of the Tibetan Scripture Hall, and knew that it was Hong Yi's thoughts that were taken back, and immediately asked.

"I didn't find anything, but the power of my soul can only be explored to about fifty or sixty zhang, and I am now ready to try it with all my strength to see how deep I can explore. In fact, no one in this world knows how high the sky is and how thick the earth is. I read books and things to know, but I want to know how thick the ground is now. ”

With that, Hong Yi returned to the tent and sat down: "You protect the Dharma for me!"

When his subordinates surrounded him, Hong Yi escaped all his soul without reservation.

A huge, warm yang and harmonious aura suddenly filled the entire square.

Everyone felt the breath, as if the day had come. The snow in the square began to melt immediately, and the fierce mountain wind outside could not blow on the ruined square.

Mr. Zhou's face changed, and only then did he really feel Hong Yi's tremendous surging power!

This force is too great, and if you divide a small force at random, you can beat him to the point that he will never be reborn.

"Enter!"

This massive, Yanghe force suddenly retracted and slammed into the ground.

The whole ground trembled slightly, and then it was as if nothing had happened, but in the feelings of everyone, it was an invisible, huge warm dragon that burrowed into the ground at once.

As soon as Hong Yi's spirit drilled into the ground, suddenly the fierce mountain wind outside blew over, the pine waves between the mountains and forests were undulating, the snow fell, and everyone felt the cold chill

"Now I'll shoot with all my might, and the ground won't be able to stop me!"

Hong Yi's spirit all burrowed into the ground, and he immediately felt ten times more refreshed than just now, like a fish in water. Going deeper and deeper, the resistance has really decreased a lot. At the same time, Hong Yi felt that the underground area had also increased a lot.

Layers of rocks, water vapor, and even underground springs and rivers are all presented in the feeling of Hongyi.

"It's quite boring underground, but it is rumored that deep in the center of the earth, there is earth and fire magma, where is it like a small sun, galloping all the time, I don't know if it's true?

Although he didn't find any dungeon, Hong Yi had some thoughts of exploration in his heart.

So he used enough divine soul power and continued to drill down to the ground.

The further down it goes, the more difficult it becomes, even with Hong Yi's current huge divine soul power, he feels a little reluctant!

"I've drilled at least more than 500 zhang now! At this depth, I'm afraid that even the ghosts and immortals who have survived a thunderstorm will be difficult to come down. But I haven't touched the magma in the core of the earth, so I don't know how thick the ground is?"

After Hong Yi drilled into the ground for more than 500 zhang, it was still mud, rocks, and nothing, and he didn't see any earth fire magma at all, so he knew that the ground was too thick, and with his current Dao cultivation, he couldn't go deep into the earth at all.

"There's no dungeon at all, so let's go back. Even if there is an underground palace, it will not be built as deep as 300 zhang! Even if the monks of the Great Zen Temple are all human immortals, it is impossible to dig 500 zhang of the ground and build any underground palace. ”

Hong Yi smiled in his heart, knowing that the underground palace of the Great Chan Temple must be gone. If you want to have a dungeon, it is impossible to drill into more than 500 zhang and not be discovered.

It is even more impossible for the underground palace to be built in a deeper place, and what kind of underground palace to build in a place five hundred zhang deep, even if all the manpower and financial resources in the whole world are gathered together, it is impossible to complete this huge project.

Where it is difficult for even Hong Yi's soul to come down, how can manpower build a dungeon?

"This time I came to the Great Zen Temple, just to remember, pay respects, and help the monk Jīng Ren make a wish, but I didn't expect that there would be any treasures on the ruins of the Great Zen Temple. ”

Hong Yi thought in his heart, and prepared to go back.

His state of mind is very peaceful, and he doesn't have disappointment and other emotions in his heart because he can't find the underground palace or anything. Because he came to the Great Zen Temple this time, he didn't come to look for treasures at all

"Hmm, how can there be a trace of mana fluctuations?"

Just as Hong Yi was about to go back, suddenly, he felt a faint trace of mana fluctuations from a Divine Soul cultivator coming from deeper underground. That is, the fluctuation of thoughts.

Although the fluctuation of this thought was extremely small, Hong Yi still felt it, and felt it very really.

"Could it be that there is still some master cultivating in the underground? How is it possible? Who will cultivate in these 500 zhang underground? I am tired of living? You know, with my cultivation, it will be difficult to come down. If I continue to go down and go up for a while, then maybe the power of the divine soul is a little insufficient!"

Hong Yi felt the fluctuation of mana, and hesitated in his heart, whether to go down or not, but in the end, it was the unknown exploration of the Heavenly Dao that attracted him, and his heart moved, and he summoned the power of the divine soul again and drilled down violently.

Hong Yi felt that this time he was drilling into more than 100 zhang, and he had reached a depth of more than 600 zhang underground!

suddenly

The whole body was relaxed, and the earth, soil, and rocks were completely removed from Hong Yi's divine soul restraint.

Suddenly, a stone chamber appeared in front of me.

"This is the underground palace? The legend is actually true? In the depths of these 600 zhang, the Great Chan Temple actually built an underground palace? How is it possible? I don't know if this underground palace has an exit to the ground? If there is an exit, the staircase of 600 zhang? How majestic and magnificent should it be?"

At this time, Hong Yi was in an empty space, and his divine soul power recovered at once.

He felt great surprise in his heart, and quickly looked at it.

"No, it's a solitary stone chamber, completely deep underground, with no way out around. Hong Yi looked at it, and his heart was even more surprised, the entire stone room was completely enclosed in a depth of six hundred zhang underground, and there were no stairs leading to the ground around it. So, it's not something that can be built by manpower at all.

"Could it be that he is a master of Taoism, and he dived into the ground like this, and then squeezed the rocks out of thin air, causing such a large stone chamber? But this kind of cultivation, I can't do it at all? Could it be that it is naturally formed?"

This stone room is not large, only a hundred steps square, and the scale of an underground palace cannot be compared at all, at best it is just a large room.

Hong Yi couldn't guess whether this stone chamber was built by a Taoist master or formed naturally.

In the entire stone room, it was actually bright, like day.

Hong Yi saw at a glance the source of this glow.

It is the most zhōngyāng of the stone room, a cylindrical step, and a sphere placed on it emits a strong light. The entire small stone chamber is illuminated with snow white and transparent.

From this sphere, Hong Yi felt a peaceful and eternal aura like the past, and this breath was exactly what he felt at a depth of five hundred zhang just now.

Only when he has practiced the past scriptures can he faintly feel this aura in the depths of the earth, otherwise, even if there is a master who is twice as high as his Dao technique, it will be difficult to feel it.

Under this sphere, which is a hundred times brighter than the night pearl, there is a thin book, and the face of the book is dark gold, and it is the same material as the destroyed "Book of the Past".

"Could it be that what the monk said is true? In the underground palace of this great Zen temple, there is really a hidden scripture of the present?" Hong Yi did not step forward to get it, but looked straight at the book pressed under the sphere, and split a trace of thoughts to see what this book was.

But!

Just as Hong Yi was approaching this sphere, suddenly, a strong light erupted above the sphere!

Hong Yi immediately felt it, and his thoughts were suddenly dispersed by this strong light!

At the same time, in the bright light of the sphere, a dragon with teeth and claws appeared.

The dragon swam among the spheres, layered on top of each other, as if there was another small world inside the sphere. And at the same time that Hong Yi's thoughts were dispersed, suddenly, the dragon's eyes immediately locked on Hong Yi, and his eyes looked towards Hong Yi.

Bang!

As soon as Hong Yi saw the dragon's eyes, he only felt an overwhelming coercion, from the vast void, constantly superimposed on his own divine soul.

The whole soul exploded immediately!

"It's amazing! It's so powerful! It's ten times more powerful than the Nine Flame Flame Dragons of the Oneiroi Machine! What is this? The Great Zen Temple actually uses this thing to protect the scriptures? It's a pity, I can't see what this scripture is? Is it the present Sutra or the Future Sutra of No Life?"

After the explosion was dispersed, Hong Yi's divine soul then condensed again.

At the same time, the dragon above the sphere disappeared again, as if it thought it had dispersed Hong Yi's spirit.

Hong Yi glanced at the sphere and the scriptures pressed underneath, and suddenly his body jumped, drilled out from the top of the stone chamber, entered the dirt and rocks, and then used the power of the divine soul to waste the power of the two tigers before he got out of the ground.

He didn't miss the orb, or the unknown scriptures pressed underneath it.

Just above the sphere, when the dragon appeared, the coercion in his eyes and a strong thought made Hong Yi feel that the whole earth was pressing on him.

Hong Yi had seen the Nine Flame Flame Dragon of the Oneiroi Machine, but even the power of the powerful Nine Flame Flame Dragon could not be compared to the dragon on the current sphere.

He knew that his current mana was strong, but it was still difficult to defeat this dragon.

Fortunately, this dragon seems to be sealed in a sphere, and it seems that it has no consciousness and will only attack the existence that approaches it. Otherwise, Hong Yi felt that he had just advanced his supernatural powers, and I am afraid that he would have to explain here

"What, Hong Yi, did you find any dungeon?"

Just as everyone was guarding Hong Yi, they suddenly felt a huge amount of sun and heating coming out of the ground.

Then it was all in Hong Yi's eyebrows, and then he opened his eyes.

Seeing Hong Yi's soul returning to his shell, Monk Jīng Shinobu hurriedly asked.
