Inside the main hall, it is like another piece of heaven and earth, Lin Bai's feet are a huge red desert, and hundreds of meters above his head, there are stars all over, I don't know what is used to form it, just like a real starry sky.

Lin Bai felt the slightly hot breath in the air, and his eyes also shook slightly, in this huge hall, there was actually a space of its own?

He glanced at Yun Tianji, it seems that the status of this ancestor of the Yun family was not low back then, but it is a pity that there was an inexplicable change in this secret realm back then, and there was no glory at all.

Along the way, Lin Bai actually had some doubts in his heart, the aura in this secret realm did not seem to be unsuitable for human survival, and the aura was much richer than that of the outside world, so why did the monks who lived here withdraw from this place back then?

Halfway through, Lin Bai and the others even passed through several small towns, as well as various attic palaces built on the mountain peaks, a dilapidated scene, but except for the collapse and destruction due to disrepair, there was no sign of natural disasters and man-made disasters, but it seemed that these people retreated in an orderly manner.

Shaking his head and not thinking about it anymore, Lin Bai glanced around, and his eyes locked on a steep solitary peak in the center of the space.

The lone peak is like a sword, standing in this space, and it is also the only conspicuous thing in this red desert.

At the top of the lonely peak, there is a faint golden light flowing, which is very extraordinary.

"It seems that on that mountain peak, there is something left by my Yun Clan Ancestor. Yun Tianji exhaled lightly, and there was excitement in his eyes that could not be concealed.

The two glanced at each other and headed towards the lonely peak, followed by Xue Hatsumi and Gouzi.

The lonely peak seems to be steep and narrow, but it is still extremely majestic after approaching, and a path at the foot of the mountain winds up, and three people and a dog climb up, gradually reaching the top.

As soon as he reached the top of the mountain, Lin Bai's complexion changed slightly, and he felt an extremely sharp Gengjin aura, and the air was filled with a chilling qi, which was agitated.

"That's ......" Lin Bai looked ahead, a huge stone pool that sprayed thin golden light, his eyes were slightly shocked, and those golden qi were emitted from this stone pool.

It was a pitch-black stone pool, occupying almost a third of the mountaintop area, half a meter above the ground, and the pool was full of golden light.

Lin Bai suddenly understood, it seemed that the golden light they saw at the bottom of the mountain should have emanated from this stone pool.

"Could it be...... Soldier Pool?" Lin Bai suddenly raised his eyebrows, remembering that in the classics of Yun Tianji, there was a record of a soldier pool, which was the place where the Yun clan raised troops back then, and it could contain extremely high-quality magic weapons.

Even in this entire secret realm, the Yun family's army cultivation pool seems to be famous, and it is heavily described by that classic.

However, according to Lin Bai's guess, thousands of years have passed, even if the soldier pool is still there, it should be completely damaged, but he didn't expect to see something suspected of being a soldier pool here, and where there is a trace of damage, it is clearly powerful.

Yun Tianji was also stunned, according to the records, the army cultivation pool consumes the essence of heaven and earth very much, and needs to be maintained frequently, and a large number of treasures containing the essence of heaven and earth can be invested in order to maintain its operation, he never thought that in the past thousands of years, this army cultivation pool is still operating.

Lin Bai looked at the doubts in Yun Tianji's eyes, and a trace of waves flashed in his heart, from the Extremely Cold Mountain Range to here, this so-called secret realm gave him an extremely strange feeling everywhere, as if all the changes in this secret realm were driven by an invisible big hand behind him.

"Let's see the move. Lin Bai shook his head, suppressed this thought, and looked in the other direction of the top of the mountain.

On the other side of the top of the mountain, opposite to the soldier pool, there is a stone platform with a diameter of meters, the stone platform is engraved with a lot of patterns, and there are also some stones containing spiritual energy, it seems that the formation should have been laid out at the beginning.

However, compared to the army pool, the stone platform does not have such good luck, and now the veins are dim, and the stones containing the aura are almost scrapped, and the stone platform has a thick layer of dust, and only a few ancient books can be vaguely seen placed on it.

In the remaining place, it seems to be a medicine garden, growing dozens of plants, all exuding a faint aura, fragrant, extremely extraordinary.

Lin Bai and Yun Tianji's eyes lit up, and they walked towards the medicine garden first.

"Shhh...... The lowest quality ones are all third-order, and there are three fourth-order treasure pills among them!" Yun Tianji looked at these dozens of plants, and instantly gasped, and then his face turned red with excitement.

In the outside world, countless people fight for life and death for the next blessed land, and at most they can get third-order treasure medicine, and even a blessed land is only a few plants at most.

However, in this medicine garden, the so-called third-order treasure medicine is just like Chinese cabbage, which is planted here at will, and there are even fourth-order treasure pills that have never been born.

Yun Tianji's body trembled, this treasure medicine, as long as he took one plant, he was afraid that he would be able to rush to the peak of the fourth order in a few days and spy on the threshold of the fifth divine aperture.

However, at this time, Yun Tianji still forcibly suppressed the heat in his eyes, looked at Lin Bai, and said with a trace of pain flashing in his eyes: "According to the previous agreement, Lord Lin can take away the treasures here at will, just hope that when you refine the fourth-order or even fifth-order replenishing Yuan Pill, you can sell me one." ”

"Then I'll take it. Lin Bai said with a smile, one of the purposes for which he came to this secret realm was to find the fourth-order treasure medicine, and now he finally had some gains.

A hint of gloom flashed in Yun Tianji's eyes, he originally thought that Lin Bai could look at the friendship between the two and leave him some.

However, this was a promise made a long time ago, and Yun Tianji didn't blame Lin Bai after a slight loss, after all, without the other party, he couldn't reach here at all.

However, after Lin Bai harvested all the treasure medicines, he smiled lightly: "I accept the love of your ancestors, naturally I will not take advantage of it in vain, and when this secret realm trip is over, I will give you three fifth-order replenishing pills." ”

"What?" Yun Tianji was stunned, trembling in disbelief, "You, are you serious?"

Now the Lin Demon King's Replenishing Yuan Pill has long been famous all over the world, and a few levels of Replenishing Yuan Pill can create a few masters, and the legend is amazing, and Yun Tianji has naturally heard of it.

Three fifth-order replenishing Yuan Pills, that is the three masters of the five tricks, this can simply make the strength of the Yun family jump directly from the first level to the second layer.

"Walk the talk. Lin Bai said with a smile, for him, a fourth-order treasure pill could refine dozens of fifth-order replenishing pills, and just three were nothing.

At this time, Xue Chujian had already swept away the dust from the stone platform and took the three ancient books on it.

"This is ......" Lin Bai took a copy, his eyes were strange, I don't know what this ancient book was made of, the paper was soft, white as a cloud, and even there seemed to be a faint cloud in the page.

On the cover of the ancient book, there are four big characters, floating clouds.

"Body spells!" Lin Bai opened the cover, looked at the introduction on the second page, and raised his eyebrows, according to this introduction, if this spell is cultivated, it can even take off in the air in a short period of time, and the speed is extremely fast, far beyond the same level.
