Double Breakthrough, Qi-grade Spiritual Secret Skill!

After following Lin Xiao to Flame City once more to purchase a batch of spirit medicine, Lin Yi returned to the Lin Family, picked up Little Yan, and headed back to Ironwood Manor.

Compared to the Lin Family, Ironwood Manor was clearly better suited for his cultivation.

To avoid keeping his family separated, Lin Yi received permission from Lin Zhentian to bring Liu Yan, Qing Tan, and Lin Dong to live at Ironwood Manor.

Meanwhile, the mining operations for the Yang Yuan Stone vein were launched under strict secrecy.

Those involved in the mining were carefully selected. The Lin Family provided these workers with extremely generous compensation and even allowed them to bring their families to live at Ironwood Manor.

In this way, not only could they be provided with housing, but it also served as an implicit warning to prevent anyone from leaking secrets.

Lin Yi naturally could not help with the mining itself, but for most of the day, he would cultivate at the Yang Yuan Stone vein, as it was filled with rich Yang Gang Qi.

When the sky grew dark, Lin Yi would return to his room to cultivate his Spiritual Energy.

During this trip to Flame City to buy spirit medicine, Lin Yi had also purchased a few herbs capable of enhancing Spiritual Energy.

Unfortunately, spirit medicines for Spiritual Energy were relatively scarce; he had only managed to buy a mere three stalks, and only one of them was a Fourth-Grade Spirit Medicine.

Fully immersed in his cultivation, both his Yuan Power and Spiritual Energy were steadily improving.

That night, Lin Yi discovered that his Spiritual Energy cultivation seemed to have reached a bottleneck; his Mud Pill Palace felt as though it had been completely filled with Spiritual Energy.

Faced with this, Lin Yi felt no nervousness, but rather a surge of joy. It seems it is time to condense the Rune Seal!

The Spirit Refining Art was a complete secret manual for Spiritual Energy cultivation. It not only contained conventional methods for training Spiritual Energy but also recorded a method for condensing seals known as the Black Hole Rune Seal, which could be used to condense a Life Spirit Rune.

Lin Yi took out the Spirit Refining Art scroll and carefully read through the detailed records of the Black Hole Rune Seal once more.

After savoring the information, Lin Yi put the scroll away, sat cross-legged, closed his eyes, and began to mobilize the Spiritual Energy within his Mud Pill Palace.

Soon, the Spiritual Energy in Lin Yi's mind began to swirl.

Gradually, the swirling Spiritual Energy transformed into the shape of a funnel within his Mud Pill Palace.

At the center of the funnel, there appeared a deep, dark hole that radiated an aura of infinite mystery!

The spiritual funnel rotated with a rhythm that was sometimes slow and sometimes fast, seemingly hiding a very peculiar cadence.

As for the black hole at its center, it was impossible to tell if it was rotating along with it.

Suddenly, Lin Yi felt a suction force emanating from that black hole. The suction was faint at first, but it gradually showed signs of strengthening.

"Condense!"

Lin Yi let out a soft shout, controlling the Spiritual Energy funnel to compress it fiercely. The black hole at the center of the funnel was also gradually compressed and shrunk, eventually turning into a tiny black dot.

"Boom!"

When the spiritual funnel was compressed to its limit, a muffled explosion suddenly echoed within Lin Yi's Mud Pill Palace, and the funnel burst apart.

As the spiritual funnel shattered, a flash of light seemed to pierce through Lin Yi's closed eyelids.

"Sizzle!"

From the center of the explosion, countless tiny rays of light suddenly shot out, instantly connecting the scattered fragments of Spiritual Energy.

Then, they rapidly retracted in a unique state, eventually forming a magical rune about the size of two fingers!

This rune was outlined by numerous fragments of Spiritual Energy. At a single glance, it gave off an extremely profound feeling, as if the very heavens and earth were contained within that seemingly simple rune.

When the rune formed, it appeared exceptionally dim and blurry, but upon closer inspection, one could discover a mysterious black dot at its center.

Under a steady gaze, the flat rune seemed to transform into a sunken funnel, and the black dot was the small hole at the bottom of the funnel, from which an endless, inexhaustible suction force emanated!

"Hiss!"

A suction force radiated from that peculiar rune, and the spiritual fragments drifting within the Mud Pill Palace were drawn into it.

The originally dim rune seemed to become a bit brighter.

"Hoo..."

When the Mud Pill Palace finally returned to a state of calm, Lin Yi slowly opened his eyes.

At this moment, he could clearly sense every movement within the entire Ironwood Manor; even the sound of breathing could not escape his perception.

"After about half a year of cultivation, I have finally become a true Rune Master!"

Lin Yi stood up, stretched, and a faint smile appeared on his face.

Ding! Detected that the host has become a One-Seal Rune Master and has officially stepped through the gates of the path of a Rune Master. Rewarding Qi-grade Spiritual Secret Skill: Spiritual Illusion Realm!

Hm? Another reward?

Lin Yi was in high spirits. He took the newly acquired reward from his Universe Ring; it was an ancient-looking scroll, and inscribed upon it was the introduction to the Spiritual Illusion Realm.

It used Spiritual Energy to manipulate the human heart, constructing a Spiritual Illusion Realm within the target's mind to trap them, making it impossible for them to escape!

Once the opponent fell into it, they would be at his mercy!

If he encountered someone with an extremely firm spiritual will or someone whose cultivation was more than a major realm higher than his own, the effect would be somewhat reduced.

Even so, this spiritual secret skill could be called a divine skill for auxiliary killing!

After finishing the introduction to the Spiritual Illusion Realm, Lin Yi felt quite satisfied.

"My Spiritual Energy won't see much improvement in the short term. From here on out, besides mastering this spiritual secret skill, I will go all out to charge toward the Heaven Origin Realm!"

After a long while, Lin Yi put away the scroll and set a new cultivation goal.

For this new stage of cultivation, besides quiet meditation and circulating his energy, Lin Yi did not forget to engage in some practical combat training.

The combat targets Lin Yi chose were the ferocious demonic beasts deep in the mountains behind Ironwood Manor.

"Roar!"

A sudden, angry roar erupted within the quiet forest, shaking the leaves until they rustled to the ground.

Following the direction of the roar, one could see a giant lion with a body entirely covered in green fur, lunging fiercely toward a youth in a cyan shirt.

As the giant lion pounced, the youth's hands moved rapidly, shifting through profound and mysterious seals.

Just as the giant lion's hideous maw was about to clamp onto the youth's throat, the hand seals he was forming came to an abrupt halt.

Then, maintaining a strange hand gesture, he unleashed a surge of exceptionally powerful Yuan Power and slammed it directly onto the giant lion's forehead.

"Bang!"

A dull thud of impact rang out, and the giant lion's massive body was sent flying backward, snapping seven or eight trees in succession before crashing heavily onto the ground.

The giant lion's forehead had even caved in!

"Roar!"

The giant lion let out a low, pained growl and struggled several times to rise, but it was all in vain, and it soon lost all signs of life.

"The Third Layer of the Mysterious Gate Seal, the power is not bad," the youth said, glancing at the dead green giant lion with a smile, quite satisfied with his result.

This youth was none other than Lin Yi.

The Green-Faced Lion was a demonic beast comparable to the Early Heaven Origin Realm. Since successfully breaking through to the Early Heaven Origin Realm a month ago, this was not the first Heaven Origin Realm beast Lin Yi had fought in the depths of the mountains, but it was certainly the easiest one yet.

"Whoosh!"

Just then, a fiery red shadow suddenly darted out from the forest, as swift as a thunderbolt!
