Eternal Sacred King

A few days later.

Within Thunderclap Valley, a green robed scholar sat on the ground. Every single breath he took gave off an odd series of sounds.

“Huff… hmm… boom!”

If someone were to stand beside the green robed scholar, they would be able to clearly hear the shocking sound of tigers and leopards through every single breath he took!

Amidst the sound of tigers and leopards, there was a rumbling thunder sound as well.

Treacherous and intense, the two completely different sounds shook at his bone marrow continuously, generating new blood!

That caused his blood to churn and flow rapidly!

Cultivating the Void Thunder Manual was easier than Su Zimo had imagined.

Be if the Marrow Cleansing section of The Mystic Classic of the Twelve Demon Kings of the Great Wilderness or the Thunder Marrow Cleansing Sutra of the Void Thunder Manual, the underlying concept was to make use of the sounds to vibrate the bone marrow such that the effect of cleansing and swapping new blood could be achieved.

With the foundation of the Marrow Cleansing section coupled with the torn page of the sutra, Su Zimo was able to comprehend the profoundness before long.

For anyone else, being in a strange place like Thunderclap Valley was something that would be extremely miserable.

However, it rendered a god-like assistance for someone like Su Zimo who was cultivating the Thunder Marrow Cleansing Sutra.

As time passed by, Su Zimo infused the Thunder Marrow Cleansing Sutra into the Marrow Cleansing section and created a unique breathing and expiration technique of his own – Tiger Leopard Thunder Sound!

He could clearly feel the demonic qi within his body being cleansed away by the sound of thunder.

However, the power within his blood was preserved perfectly.

Moreover, his Power of Blood turned even stronger and terrifying with the help of the Thunder Marrow Cleansing Sutra!

In just a month, Su Zimo had already achieved lesser mastery with the Marrow Cleansing section.

According to The Mystic Classic of the Twelve Demon Kings of the Great Wilderness, a lesser mastery of the Marrow Cleansing section enables the user to kill an early-stage Foundation Establishment Cultivator with ease. In fact, they can even stand against mid-stage Foundation Establishment Cultivators!

However, Su Zimo’s circumstances were different.

Since the Thunder Marrow Cleansing Sutra enhanced his Power of Blood with an additional ferocious, thunderous power, he could even hold his own against late-stage Foundation Establishment Cultivators!

But of course, that was in terms of pure brute force.

Strength was only one of the factors in a fight between cultivators.

In the blink of an eye, Su Zimo had spent three months in Thunderclap Valley.

To his delight, most of the demonic qi within his blood had been cleansed in this period of time.

The new blood generated by cultivating the Tiger Leopard Thunder Sound would contain demonic qi. However, it would be cleansed away by the thunder sounds at the same time.

From now on, Su Zimo could not only continue to cultivate The Mystic Classic of the Twelve Demon Kings of the Great Wilderness, he could even activate his Power of Blood without any additional considerations.

This was going to be his greatest trump card!

From this day forth, Su Zimo wore the Mystic Gold Silk Armor under his green robes and underwent arduous cultivation in Thunderclap Valley bearing the heavy load.

Initially, he was not used to it.

Wearing the Mystic Gold Silk Armor was akin to carrying a mountain on his back. It was extremely difficult to move or dodge, much less cultivate the multiple killing techniques of The Mystic Classic of the Twelve Demon Kings of the Great Wilderness.

However, as time went by, his Power of Blood became stronger and Su Zimo gradually adapted to things. All of his motions soon looked identical to how he normally was.

Even if anyone saw him again, they would not notice that he was actually wearing an inner armor that weighed 5 tons!

An intense cultivation as such had clear effects on the tempering of his skin, flesh, tendons and bones.

His Body Tempering, Tendons Transformation, Bones Strengthening and Marrow Cleansing sections all made progress at the same time.

But of course, that was not the only surprise the ancient technique of the Void Thunder Manual brought for Su Zimo.

On the torn page, there were also a few other thunder arts.

Initially, Su Zimo paid no attention to them.

After all, thunder arts were a type of spirit art. Because he had not reached Foundation Establishment realm yet, his spirit qi had not transformed into spirit energy. As such, even if he learned them, he would not be able to unleash their potential.

However, after cultivating the Thunder Marrow Cleansing Sutra, Su Zimo realized that there was a Power of Thunder within his blood!

Hidden deep within his blood, that power did not belong to the scope of spirit energy. However, by making use of that Power of Thunder, Su Zimo was able to cultivate the thunder arts on the torn page as well as unleash them!

This meant that Su Zimo was not able to unleash spirit arts that only Foundation Establishment Cultivators could use even as a Qi Refinement Warrior.

Furthermore, they were thunder arts – the most powerful type of spirit arts!

Since he did not have a thunder spirit root, Su Zimo was not as sensitive towards lightning and it was difficult for him to cultivate in that direction as well.

However, since he was in Thunderclap Valley, Su Zimo received the first thunder in spring.

In the skies, a bolt of lightning flashed and coiled like a snake. It seemed to tear through the sky as it plummeted, bringing with it an aura of destruction.

In order to better understand the power of thunder, Su Zimo decided to try and draw lightning into his body.

This was an extremely dangerous act.

Each time, Su Zimo’s body was charred black from the electricity. His skin was split open and his body was covered in wounds.

Even though he was wearing the Mystic Gold Silk Armor, he could not withstand it at all!

Fortunately, Su Zimo’s healing powers were astonishing after cultivating The Mystic Classic of the Twelve Demon Kings of the Great Wilderness. He only needed a few days of rest to return to normal.

Within this valley, Su Zimo suffered unimaginable torture and pain.

He wanted to become stronger!

Strong enough to take revenge for Zhui Feng; strong enough to stand tall in front of Shen Mengqi once more; strong enough to pursue in Die Yue’s footsteps!

Each time Su Zimo wanted to give him, he would recall what Die Yue told him.

“To become one of the greatest, you have to work on the foundation and be willing to take hardship and serve others!”

The path of cultivation was a heavenly defying act to begin with, not to mention cultivating the immortality and demonic path at the same time!

From the moment he started on this path, Su Zimo was destined to suffer more hardships and pains than others!

After cultivating the different thunder arts on that torn page, Su Zimo had memorized everything on that page in his mind.

At the very end of that torn page, there was mention of a unique thunder art – Thunderclap Kill

Most thunder arts were released by the unleashing of the power of thunder.

However, Thunderclap Kill purely made use of the power of the sound of thunder!

The power of sound!

The power of sound was something that was easily neglected, but it contained unimaginable power.

Making use of sound to shake the bones and rejuvenate the marrow was a manifestation of the power of sound.

At the end of the day, thunder arts required hand seals and activation of mental cultivation to release. However, the power of sound was an instantaneous power!

If used properly in battle, it would produce an unexpected effect.

It was a pity that someone had torn away the page and Su Zimo was unable to learn from the Thunderclap Kill section.

However, back in Cang Lang Mountain Range, Su Zimo had witnessed a powerful spirit demon kill a spirit beast on the spot by erupting forth an indomitable roar.

That memory was still fresh in Su Zimo’s mind till this day and it gave him some inspiration.

Time flew and in the blink of an eye, Su Zimo had spent half a year in Thunderclap Valley.

To the sect disciples, they were certain that Su Zimo would definitely have a difficult time raising his cultivation since he was trapped in Thunderclap Valley.

However, no one knew that he had actually undergone a complete transformation here. Even though his cultivation did not rise, his fighting strength had risen by more than twice!
