Without the interference of the Black Water Snake, Lin Nuo searched all the way along the seaside, and it didn't take long to find the blood-dripping cave hidden in the mountain rock.

Eight hundred years ago, the black-hearted old man's blood refining hall was known as the first faction of the Demon Sect at that time, with extremely strong strength and masters, and the black-hearted old man himself was an ancestor-level figure on the path of cultivation, but after the years changed, and he fought with the righteous path several times, and the blood refining hall gradually declined and was replaced by other factions.

In today's world, the four major factions in the Demon Sect stand side by side, namely the Hehuan Sect, the Ten Thousand Poison Sect, the Immortal Hall, and the Ghost King Sect, but when it comes to the prosperity of the momentum, none of them can compare to the Blood Refining Hall that was at its peak back then.

In the Demon Sect, in the past 800 years, it has been rumored that after the Great War between the Righteous and the Demons, although all the main leaders of the Blood Refining Hall were killed in battle, many secret treasures and magic weapons were stored in a secret place called the "Dripping Blood Cave" under the "Ten Thousand Bat Ancient Cave", the foundation of the Blood Refining Hall.

In the past 800 years, I don't know how many people in the Demon Sect have secretly stolen the Ten Thousand Bat Ancient Caves, and even the Necromantic Abyss has been searched all over, but they have all returned empty-handed.

And today, with his familiarity with the plot and the assistance of his divine sense, Lin Nuo finally found the location of the blood dripping cave under a stone wall with ancient trees.

With a punch of his hand, he smashed the rock under the ancient tree, and the next moment, a cave passage less than two people wide appeared in his eyes.

After walking for dozens of meters along the passage, I finally entered a mysterious cave made of red rocks.

The cave was red, and there was nothing else except for some stone chairs and stone tables, and Lin Nuo was not surprised by this, but came directly to the waterhole at the end of the cave, and according to the information from the divine sense, his body quickly changed his position, and every time, he was in the waterhole, and pressed a palm.

After doing this a few times, a clicking sound suddenly came from the end of the cavern, and the next moment, the stone wall, which had been seamless and extremely hard, actually retreated back in one piece, and although it was slow, a new hole was finally revealed.

This is a cave leading to the belly of the mountain, and there is a deep and dim passage connected to the cave entrance, Lin Nuo's heart moved, and the true yuan conjured up an orange shield, and after wrapping it, he walked forward cautiously.

Although there is no danger in this passage in the detection of the divine sense, there are some things, even the divine consciousness may not be able to fully detect clearly, and Lin Nuo has always maintained a cautious attitude in the face of the unknown.

At Lin Nuo's speed, it didn't take long for him to follow the passage to the center of the mountainside, and the next moment, a stone chamber that didn't look very wide appeared in his field of vision.

On the left side of the stone room, there are two huge stone statues, one is kind and smiling, and the clothes are carved like the wind blowing, but it is a bit like the Guanyin Bodhisattva of Buddhism.

The other one is completely different, hideous and vicious, with black faces and ghost horns, eight hands and four heads, and even a trace of blood is engraved on the side of the mouth, which makes people shudder.

In addition, in front of these two statues, there is a stone table, an incense burner on it, and several packets of incense candles are placed next to it, all of which are dusty, and it is estimated that there has never been incense in the past 800 years.

Lin Nuo took a look, in this stone room, there was nothing of value except for the two statues, and he no longer stayed at the moment, but continued to move along the passage in front of him.

Not long after, another stone room appeared in front of his eyes.

This is a stone chamber built in the stalactite, the stone chamber is full of stalactites of all kinds of strange colors, and the colors are also colorful, and in front of Lin Nuo, there is a huge monument, on which the dragon and the phoenix dance are engraved with ten big characters: Heaven and earth are not benevolent, and all things are dogs!

These ten big characters, each word is almost half the size of a person, the pen is clumsy, the gesture is vigorous, straight to the dragon and snake, there is a head-on, roaring sky.

Seeing this stone stele, Lin Nuo's consciousness dispersed, and then his figure flickered, and he directly entered another stone room next door, this stone room was empty, but the stone wall was densely covered with stone inscriptions.

These words are the first volume of the Book of Heaven that Lin Nuo has been looking for on this trip, that is, the general outline of the five volumes of the Book of Heaven.

When the heaven and the earth are created, the cover is chaotic, the ignorance is not divided, the sun and the moon contain their brilliance, the heaven and the earth are mixed with their bodies, and the outline is changed, and the turbidity is Chen.

Heaven and earth can last for a long time, because they do not generate by themselves, so they can last for a long time. However, all things in heaven and earth have their own appearances, and all living beings are obsessed, confused by my appearance, human appearance, sentient beings' appearance, and longevity appearance, thinking that everyone is the same, and the heart has three poisons, three fears and three horrors, which cannot be long.

There is no punishment in the heavens, and there is no name in the praise, so it is said that there is no self, no one, no sentient beings, and no longevity, that is, the light. Those who hold a righteous path, the inner body is self-natured, and the heaven and earth are also based on the heart.

Therefore, in the place of movement, it is the heart of heaven and earth to see.

Therefore, there is no reality and no fiction.

Therefore, heaven and earth are left to nature, and nothing is done and nothing is created.

If you don't have it, you won't be able to prepare it!

.......

Lin Nuo stared at the words on the stone wall, his expression was solemn at first, but after a while, the whole person seemed to have fallen into an epiphany, standing in place, motionless.

It wasn't until three days later that Lin Nuo woke up from his state of epiphany, and the aura on his body continued to rise, more than twice as much as before, before it gradually converged and dissipated.

And in front of him, around the original orange defensive shield, at some point, there was an extra ball of thunder and lightning light, and the thunder flashed, like a small golden dragon, constantly circling and wandering in the flame shield, as if it had spirituality.

Lin Nuo exhaled lightly, feeling that the golden pill in the dantian had become much larger than before, and he couldn't help but feel a little happy in his heart. This trip to the Blood Cave was not in vain.

An epiphany made him comprehend the mysteries of thunder and lightning in the second relief pattern of the God of War catalog, and even broke through to the realm of the middle stage of sainthood.

Glancing deeply at the words on the stone wall again, Lin Nuo's face was pensive.

Obviously, the content in the first volume of this Heavenly Book was not naturally formed, but was left by the power of the cultivation world, but who left it, Lin Nuo had no way of knowing.

After all, even at the end of the plot of Zhuxian, the origin of the five volumes of the book is unclear, and no exact information is given.

The next moment, Lin Nuo separated a trace of divine consciousness and entered the second layer of the small tower, and in the circle of light above the altar of Na Shouyuan, he gently placed a technique called the first volume of the Book of Heaven.

The next moment, a string of information appeared in his mind.

"The first volume of the Book of Heaven, enter the Holy Great Perfection level exercises, collect five volumes, and you can get the demigod primary exercises...... The complete version of the Book of Heaven can consume a hundred years of lifespan and fuse with the God of War Catalogue (Jane), and after the fusion, there is a great chance to obtain the Demigod Great Perfection level exercises!"
