Obtaining the Source Heavenly Book, Leaving Purple Mountain

Lin Yu continued forward, heading deeper into Purple Mountain. This time, he had unexpectedly refined the Demon God Seal in front of the purple jade wall, which was a pleasant surprise.

However, that jade wall couldn't be taken away, so he still needed to find the Source Heavenly Book.

The Source Technique lineage studies the terrain of mountains and rivers, dragon veins, and feng shui. Unlike ordinary cultivators, they are closer to the art of feng shui formations. They have realms like Source Earth Master, Source Heavenly Master, and Source Emperor.

Source Heavenly Masters are common, but Source Emperors are rarely seen. Only Duan De's second life as the Underworld Venerable seemed to have reached this realm. He built the Ninety-Nine Dragon Mountain, a massive source formation, for Emperor Venerable, nurturing the Immortal Ascension Cauldron, an immortal artifact.

What's interesting is that the Source Technique lineage worships the Source Emperor as their patriarch. The Source Emperor created Source Gods and Source Ghosts, and the Source Gods and Source Ghosts, in turn, cursed Source Heavenly Masters with misfortune in their later years, creating a true closed loop.

Although Lin Yu had refined the Hell Furnace, which was said to be able to squeeze oil out of stones, as the saying goes, if you eat stones every day, isn't that "someone can't eat fine grains"?

His cultivation was so slow, when could he achieve his dream of suppressing the Forbidden Zone and sweeping across the world!

After walking for two or three miles like this, Lin Yu reached the depths of the mine shaft and discovered a large Source Stone sealing a beautiful and ethereal-looking woman.

Next to it was a stone carving of Zhang Jiye paying respects. It should be Yang Yi, the Jade Lake Holy Maiden from ten thousand years ago. Back then, she committed suicide for love for the Source Heavenly Master Zhang Lin, and he sealed her in a Special Divine Source using Source Heavenly Master techniques, preserving a trace of vitality.

Next to them lay the collapsed corpse of a Primordial Being. This was done by the Source Heavenly Master Zhang Lin, who had transformed into a half-human, half-something being and had been guarding Yang Yi here ever since.

"Thirty years I sought the swordsman, how many times have leaves fallen and branches sprouted? Since I first saw the peach blossoms, I have never doubted again."

"My current cultivation is too low, I can't save you yet." Lin Yu sighed, then turned and walked forward!

Further on, he encountered a group of Yin People and Yin Horses that had run out of a Yin Meridian. They all became Lin Yu's takeout.

"Why pick on me of all people? Don't you know I'm a professional at demon extermination?" Lin Yu opened the Hell Furnace and refined them into ashes with a single flame.

Suddenly, Lin Yu felt a gaze watching him. He turned around and saw a Primordial Being with a snake-like lower body, as thick as a water vat and dozens of meters long. Its upper body resembled a human with black beast fur. It was charging at him from behind, its large black hand reaching out to strangle him.

These were the gatekeepers left by those self-sealed Primordial Beings. They were originally sealed within the source, but now that the seal was broken, they basically couldn't go back, so they were a bit grumpy from being woken up.

Lin Yu's back flickered, and the Wings of the Demon shimmered, allowing him to dodge its attack.

"Spear of the Underworld God!"

In Lin Yu's hand appeared a Spear of the Underworld God. Dark golden blood converged into hellish patterns, constantly intertwining. A melody from hell began to resonate, dominating life and death.

With a single thrust of the Spear of the Underworld God, it instantly left two bloody holes in the large hand. A searing pain that reached the soul caused the Primordial Being to let out a mournful scream.

At this moment, a fierce wind surged in the distance, and a mournful howl echoed.

A strange bird over ten meters long charged over. It had no feathers, its entire body covered in scales. Unfortunately, its body was too large to fly, so it could only run on the ground.

"Oh, are they starting to call for backup?"

Lin Yu was fearless. He shook the long spear, making it over ten meters long, the same size as the strange bird. A hellish vortex appeared, deflecting the large bird's attack.

The two monsters attacked from the left and right, their killing intent soaring, eager to kill Lin Yu immediately. Lin Yu was not flustered at all, taking advantage of their massive size to dodge and weave through the air.

The dark golden vortex on the Spear of the Underworld God continuously absorbed their attacks into the Hell Furnace within his body, making him stronger the more he fought.

"Hell Furnace"

A distorted force field appeared in the surrounding space for hundreds of steps. The attacks of the two Primordial Beings were distorted by the force field upon hitting it and were drawn into the Hell Furnace. Not even sound could escape.

The Primordial Beings were horrified. They wanted to escape and call for higher-level members of their race to kill Lin Yu, but they were pulled by the force field and involuntarily drawn closer to the Hell Furnace. Finally, they all plunged into it.

"Just so-so, better than nothing! A few more might be enough for a single particle."

The Hell True Flame burned, refining the two Primordial Beings into life essence. Lin Yu smacked his lips.

Without the interference of the Primordial Beings, the path ahead was relatively calm. Soon, Lin Yu entered a vast and empty hall.

The hall was spacious. Lin Yu immediately saw a skeleton covered in wounds and a silver book.

"This should be Zhang Jiye, Grandpa Zhang Wu's ancestor, and the Source Heavenly Book. I didn't expect him to follow in his ancestor's footsteps and ultimately fall here."

Lin Yu picked up the silver book. It was made of metal, about a hundred pages thick, and felt exceptionally heavy in his hand. On it were three ancient characters: Source Heavenly Book.

Opening it, a line of characters shone brightly, entering his eyes:

"Looking up, observe the phenomena in the sky; looking down, observe the principles on the earth; observe the patterns of birds and beasts, and the suitability of the land...

Internal qi germinates, external qi takes shape, internal and external interact...

Above corresponds to the celestial phenomena, below presents the topography, heaven and earth are formed, the hexagrams move stably..."

It was not only a book teaching how to find sources, but also explained how to approach the Dao through sources, ultimately reaching the realm of unity between heaven and man.

It emphasized examining the shapes of mountains and rivers, the structure of the terrain, and the changes in celestial phenomena. It involved Yin and Yang, the Five Elements, and even the method of human-celestial induction, which was profound and difficult to understand.

Lin Yu quickly flipped through it and saw a line of small characters at the end:

"In the center of the valley, there is no valley; formless and shadowless, neither contrary nor disobedient, dwelling in lowliness without moving, maintaining stillness without decline, the valley is formed by it, yet its form is not seen..."

This was the introductory passage of the Western Emperor Scripture given to Zhang Lin by the Jade Lake Holy Maiden, hoping he could use it to cultivate his nature and prolong his life.

Putting away the Source Heavenly Book, Lin Yu prepared to study it later. He also collected Zhang Jiye's bones and took them back to the stone village so he could return to his roots.

Lin Yu walked out of the hall and came to the Beginningless Scripture. The terrain here resembled an altar, with the stone scripture placed on it. It was a stone book, over ten meters long and one or two meters thick.

Above it, he saw three large characters: Beginningless Scripture!

Lin Yu walked up and tried touching it, but there was no reaction, as expected. It seemed he had to wait for the Innate Sacred Body Dao Embryo.

At this moment, the Emperor Jade he carried also began to glow, resonating with the Beginningless Scripture. Lin Yu saw a groove on the altar, which was the place to put the Emperor Jade.

Unfortunately, the Emperor Jade was incomplete and could only be used as an admission ticket.

Not far away, Lin Yu saw a few lines of text on the stone wall. Some were left by Jiang Taixu:

"Great Emperor Wushi's achievements reach the pinnacle of creation, shaking the past and present. Alas, to be unable to witness his methods is the greatest regret of my life..."

There was also text from Gu Tianshu:

"Who stands at the peak at the end of the immortal road? Upon seeing Wushi, the Dao becomes empty..."

Behind the stone inscriptions, vines covered the ground, lush and green. The ancient mines were overgrown with plants, and the demonic power emanated through them.

After briefly admiring the greatness of Great Emperor Wushi, he prepared to leave Purple Mountain.

Lin Yu came to the groove in the altar and placed the Emperor Jade on it. The moment the ancient jade sank in, the area became dazzling, light shot into the sky, and a massive light screen instantly enveloped him. The formation patterns activated, beginning to traverse the void.
