When the Small black cat heard Lin Bai's words, it shook its head like a rattle drum. Lin Bai was helpless, he could only exhort He Shaoyu a little, and then personally go into the Sky Cavern to check.

Although the hole outside the Sky Cavern was small, it was quite spacious inside. As Lin Bai and He Shaoyu walked up there, they did not feel crowded either.

After walking forward for a short distance, Lin Bai realized that the water vapor on the two walls of the Sky Cavern had already turned into ice due to the Yin energy, and the soft soil had also become frozen.

"How thick must the Yin energy be in order to turn this area into frozen soil in the middle of the summer?" Lin Bai sighed, and raised his head to look at the ice hanging on the ceiling of the cave.

He Shaoyu was also amazed when he saw the scenery inside the cave. It was a long summer and the weather outside was extremely hot. Even if one sat in the air-conditioned room, they would still feel the heat. However, he felt as if the coldness in the air had seeped into his bone marrow.

A few steps away was like the transition between the tropical and northern poles around the equator.

"There are two figures there!" He Shaoyu suddenly covered his mouth as he pointed panickedly at a black shadow leaning on the wall in front of him.

Lin Bai shushed him with a finger and then patted his shoulder, indicating him to stay put and wait. Then, he slowly walked towards the direction of the black shadow.

With a single step, Lin Bai felt the cold air around him explode, the bone-piercing coldness directly penetrating through his skin and into his bone marrow. It was a good thing that Lin Bai's body was nurtured by Li Tianyuan since he was young. If it was a normal person like He Shaoyu, he would have long since fainted from the cold.

After walking a few steps forward, Lin Bai finally saw clearly the identity of the two black shadows against the wall that He Shaoyu had discovered. These two black shadows should be the two bold people who entered the Sky Cavern just now, as the grandpa had said.

Although they had been dead for some time, their remains were still intact due to the cold weather in the sky ditch. However, there was a thick layer of ice crystal covering their clothes. Their faces were pale and their eyes were wide open as they stared into the depths of the sky ditch.

Seeing the huge package beside the two, Lin Bai opened the zip with suspicion. After the zipper was pulled open, the ice crystals rustled down, and quite a few items rolled out of the package with tinkling sounds.

Lin Bai looked at the items scattered on the ground and the corner of his mouth curled up.

"People die for money, birds die for food. For tomb robbers to come to this Yin Field, it must be because you all are tired of living. " Lin Bai muttered to himself, after kicking the tombstone that was scattered on the ground to the side with a smile.

These people probably came to know about the information in the Sky Cavern and thought that some ancient tomb in the Moyuz had collapsed due to the invasion of time, so they came here to find a way to earn some money. However, he didn't expect to meet the Yin Field, which was a place only seen once in a hundred years.

The Baleful Yin Force from the Yin Field was already an intruder, not to mention the teachers who had done countless things all year round without seeing the light of day. Because these people frequently came in contact with tombs, they were unconsciously filled with the aura of death. Now that they were being attacked by the Yin energy, their minds were thrown into chaos and they were frozen to death here.

Just by looking at the two's bodies, Lin Bai did not dare to move forward anymore. Although his body was much stronger than ordinary people, this Yin Field was very strange. No one knew what would happen if they went deeper. Therefore, Lin Bai squatted down and carefully observed what was happening in front of him.

Starting from the two dead men, the color of the soil in the cave had changed drastically. Following Lin Bai's gaze, they all became thick layers of ice, looking crystal clear, like the crystal palaces in the legends.

However, beneath this charming appearance was an extremely terrifying Baleful Yin Force.

"The circulation of baleful qi is completely different from the one I encountered before, and the killing intent soared to the heavens. It seems like after the two of them died, they had already thoroughly activated this baleful Yin energy." The circulation of baleful qi is completely different from the one I encountered before, and the killing intent soared to the heavens.

After Lin Bai opened his Heaven's Eyes, he carefully observed the direction of the Evil Yin energy flow in the cave. However, he found that after releasing his Qi, he had not followed the Evil Yin energy around. The Yin energy from the Yin Field actually had the urge to wipe out his consciousness!

According to common sense, the movement of infernal energy was in accordance with the laws of the world. Moreover, it could be said that damage to the human body was done unconsciously. Just like the spread of germs, only when you come into contact with it will you become infected. However, the Baleful Yin Force here was completely different from the usual Baleful Yin Force. It seemed to be on the verge of slaughtering any living beings.

If the Baleful Yin Force of the Yin Field leaked out from the Sky Cavern, the lively Dashu Village would become a ghost village overnight. Moreover, it was not certain that under the invasion of Yin Qi, there would be a few Yin Corpses that would be born.

"The infernal energy is so powerful, and yet it came in such a hurry this time, how can we break it?!" The more Lin Bai thought about it, the more shocked he became.

According to Lin Bai's plan before, he would use a large amount of jade stones to arrange an array formation and control the Baleful Yin Force. The Baleful Yin Force would slowly leak out and neutralize the Yang Energy in the surrounding heaven and earth, preventing it from causing disasters.

Currently, the price of the jade had suddenly soared under the control of the peddlers. Even though Lin Bai had raised quite a large amount of money from Du Chensheng, if he wanted to use that money to arrange the array, it was still far from enough. Furthermore, Lin Bai came here today just because of a sudden thought, the cash was already in his account, where would he find any jade?

The death of these two tomb robbers in the Sky Cavern had completely disrupted Lin Bai's plans. According to the flow of the Baleful Yin Force in the Sky Eye, it would take at least half a month or even ten days to leak out.

"I wonder if this Innate Book can absorb the Yin energy in this Yin Field." Lin Bai thought about it again and again, thinking about how the will of Li Chunfeng said that the levelling of Innate Book required a lot of Yin Energy, and his heart skipped a beat. If the Innate Book was truly able to absorb all the Yin Energy in the Yin Field, it might even be able to open the third book of the Heavenly Book.

This thought made Lin Bai's heart thump, he extended his hand out, wanting to take the Innate Book out from his pocket. It had to be known that the first two volumes of Innate Book were already profound enough, but even Li Chunfeng was unable to open the third book, how mystical must it be?

Lin Bai reached out his hand, and Small black cat's eyes that was lying on his shoulder suddenly opened, raising its fluffy little claws, wanting to press Lin Bai's hand back down. But by the time the claws reached out, it was already too late. Lin Bai had already fished out the Innate Book.

Before he even had the chance to feel the strange movements of the Small black cat, Lin Bai felt that the Innate Book in his hand had turned into a block of ice that was so cold it could pierce through bones. Suddenly feeling the coldness, Lin Bai's hands trembled, and the Innate Book fell straight to the ground, and with a speed that could be seen with the naked eye, it became dark.

The Baleful Yin Force from the Yin Field seemed to have met the most delicious meal as it blotted out the sky and covered the earth and rushed towards Lin Bai, practically engulfing him within it.

The Innate Book on the ground seemed to have sensed the crisis Lin Bai was in, and just like usual, it suddenly produced an extremely strong absorbing force around him, causing the Baleful Yin Force that blotted the sky and covered the ground to be twisted, and rushed towards the Innate Book.

A land of absolute Yin was a dangerous place created by the accumulation of a large amount of Baleful Yin Force, so how could the Innate Book absorb all of the Baleful Yin Force in one go? However, no matter how much Yin Qi came in, the Innate Book seemed to be able to absorb as much as it wanted, and the two of them continued to maintain a stalemate.

"There's hope!" Seeing the Innate Book's performance, Lin Bai revealed a face full of joy. If the Innate Book was truly able to absorb all of the Baleful Yin Force in this place, even if it was unable to open the third volume of the Heavenly Tome Monolith, it should be able to open the second half of the second volume.

But before Lin Bai could reveal his joy, he opened his Heaven's Eyes and discovered that the circulation route of the Yin Energy in the Yin Field had become strange, as it had lost its previous route and had become berserk. It rushed towards Lin Bai in a wave, and the Innate Book on the ground actually started to lose the power to resist.

Not only Lin Bai, even He Shaoyu, who was far behind him, felt the temperature in the cave suddenly drop by a lot. At the start, he only felt that his body was cold, but now, he felt that the bone marrow in his body was practically frozen as the cold energy pricked his body, causing him to feel pain.

He Shaoyu shouted at Lin Bai with a trembling voice: "Brother Lin, why is it so cold all of a sudden, do we need to go out?!"

Lin Bai was also a nimble person, when he saw the situation turn sour, he immediately wanted to retreat. However, before he could even move his legs, he felt a burst of cold air blowing towards him. Lin Bai cried out in pain in his heart, he knew that it was too late for him to retreat now, as the Yin energy had already surrounded him.

"Get out of here quickly!" Using all of his strength, Lin Bai roared at He Shaoyu who was behind him.

Although he was screaming 'suffering' in his heart, Lin Bai's hands did not dare to relax as he released one incantation after another, trying his best to block the Yin Energy outside his body.

Lin Bai used all the hand seals one by one, but to no avail. As Lin Bai saw the Baleful Yin Force in the depths of the Yin Field surge even more violently, he was completely dumbfounded.

"Brother Lin!" He Shaoyu, who had escaped out of the cave, shouted into the cave. He was so far away from Lin Bai that his face had even turned deathly pale, he did not dare imagine what Lin Bai would look like now.
