Han Li stood at the edge of the plaza, gazing at the peculiar scenery within the secret realm, his gaze somewhat unfocused, his mind clearly elsewhere.

He had been here for over a month, and had already thoroughly explored the environment, except for the Great Gully. The only way in and out was through that single entrance, so he only needed to place a set of restrictions outside the entrance and leave a wisp of divine sense there. This would allow him to detect Gu Jie's pursuit before he even reached the secret realm.

Of course, because there was only one entrance and exit, it would also be more troublesome for him to escape from here.

To solve this problem, Han Li had previously made a trip to a secluded sea cliff near the Thunderstorm Sea at the southern end of the Gu Yun Continent and carved out a cave.

Inside the cave, he used nine Thunder-Restraining Woods to set up a stable lightning array capable of ultra-long-distance teleportation, and placed a divine soul mark there.

Afterward, as long as he was near the Gu Yun Continent, he could instantly teleport there by using the lightning array and connecting his divine soul with the divine soul mark on that lightning array.

If Gu Jie really pursued him here, he could also teleport there as quickly as possible, and then escape into the Thunderstorm Sea. This would give him a good chance of evading Gu Jie's pursuit.

However, this lightning array, because it was in a constant state of activation, consumed the lightning power within the Thunder-Restraining Woods every moment. At most, it could only last for less than a hundred years before it would completely lose its function due to the exhaustion of lightning power.

"Since I'm here, I might as well settle down. Let's deal with the matter at hand first." Han Li muttered to himself, patting the white jade railing with his hands, and turned to walk towards the cave dwelling on the other side of the plaza.

Back in the secret room inside the dwelling, Han Li sat down cross-legged, flipped his hand, and two thin yellow paper pages appeared in his palm. He carefully examined them.

These two pages were not inscribed with anything else, but the formulas for the Tongyuan Pill and the Chunlin Pill.

Han Li wanted to improve his strength and cultivation as soon as possible, so he had to refine a large number of Earth-Grade pills to aid his cultivation.

Currently, he had quite a bit of experience in refining the Tongyuan Pill, and his success rate was much higher than before. Although he had never refined the Chunlin Pill, he believed that the difficulty would not be too great with the True Words Treasure Wheel's assistance.

Currently, he did not lack the spiritual herbs needed to refine these two pills. However, for the sake of long-term planning, he had planted most of the spiritual herb seeds in the private spiritual herb garden in the cave dwelling after he first arrived here.

He was clear in his heart that although he already had two Earth-Grade pill formulas in his hands, taking the same kind of pill for a long time would inevitably lead to drug resistance. When the efficacy of the pill decreased, it would not only waste spiritual herbs, but also slow down his cultivation speed.

Therefore, he needed more different kinds of pill formulas to refine more Earth-Grade pills.

Long ago, he had posted a task in the Unstable Alliance to exchange for Earth-Grade pill formulas, but because pill formulas were too precious, most Earth-Grade alchemists were unwilling to trade them, so he had never been able to get what he wanted.

With this thought in mind, Han Li flipped his hand, and a purple jade box appeared in his palm, the one he had obtained from Ping Yaozi.

This object was so treasured and heavily sealed by someone with near Heavenly Alchemist attainments, so the contents inside might be the pill formulas that alchemists valued as much as their lives.

He scanned the dense lines on the purple box, shook his wrist, and more than a dozen inch-sized black flags appeared in front of him. The flag bodies were jet-black, the material like iron, and many complex and inexplicable dark patterns were engraved on them.

Han Li picked up these iron flags and inserted them one by one into the stone slab ground in front of him in a circular shape. Then, he raised a finger, gently tapped, and embedded them into the ground, repeatedly drawing between these iron flags.

Before long, a rather complex small magic array appeared on the ground.

Han Li placed the purple jade box in the center of the magic array, then joined his two fingers together, pinched a magic seal, and chanted silently.

As the chanting sound rang out, the dark patterns on the black iron flags and the array patterns carved on the ground lit up.

"Activate."

Han Li uttered a soft shout.

The entire magic array suddenly burst out with a dazzling light, engulfing the entire purple jade box.

There was a soft "chi" sound.

The silver talisman tightly attached to the jade box lit up, and actually began to burn directly.

As the purple jade box was scorched by the flames, the patterns engraved on the surface also lit up, illuminating the entire box body as crystal clear, like an extremely exquisite amethyst. Before Han Li could finish appreciating this beautiful scene, the jade box suddenly trembled violently, and the lines on the surface became brighter and brighter, as if they were about to crack open.

"How could this be..."

Han Li's heart tightened, and a blue light lit up in his eyes. The Bright Sight Spirit Eyes were immediately activated.

Within the purple jade box, hidden runes that were difficult to discern with the naked eye were shining brightly, and were about to activate self-destruction power, completely shattering the entire jade box and its contents.

The jade box's sealing technique actually had two layers, a bright one and a hidden one. If only the silver talisman on the surface was removed, the hidden runes inside would activate, causing an irreversible consequence.

At this critical moment, Han Li silently chanted the True Words Treasure Wheel incantation. Golden light burst forth from his body, and a golden wheel about a foot in size suddenly appeared behind him, slowly rotating.

As his mind turned, the True Words Treasure Wheel rotated rapidly, and countless golden ripples spread out, spreading towards the surrounding area, instantly covering the area within ten zhang.

Everything in the secret room, except for Han Li himself, suddenly slowed down.

The light of the runes within the purple jade box, which had previously appeared to be lit for a long time due to its speed, slowed down. Only then did Han Li realize that it was actually flashing on and off.

He joined his fingers, moved his fingers like flying, and moved his hands back and forth on the ground like phantoms, quickly picking up the black iron flags and re-arranging a small magic array in an instant.

"Activate."

Han Li uttered a soft shout. The magic array burst out with light, and strands of black light, like small arrows, shot from the black iron flags into the purple jade box.

Within the jade box, the light of the hidden runes converged, stopped flashing, and then silently dissipated. The flames burning outside the jade box also gradually became smaller.

When the talisman flames were completely extinguished, the patterns on the purple jade box gradually dimmed and disappeared. A soft "pa" sound came from the box, and it actually opened on its own.

Han Li retracted the True Words Treasure Wheel into his body, reached out and grabbed it, and the purple jade box flew into the air and landed in his palm.

He had already arranged a layer of high-level forbidden arrays outside the entire secret room, so he was not worried that there were any unknown means within the jade box that would expose his current location.

He concentrated and looked, and saw that the entire jade box was empty, with only a stack of thin, light gold paper pages lying quietly at the bottom of the box.

Upon seeing this, Han Li first released his divine sense to scan it, and found that there were no divine sense imprints on it. Only then did he raise his hand to pick it up, hold it in his hand, and examine it carefully.

On the top sheet of paper, the three large characters "Cheng Wan Pill" were written in ancient seal script. Below it, in a slightly smaller font, were written the names, years, and dosages of the various spiritual herbs, as well as the refining methods.

A look of joy appeared on Han Li's face. As he had expected, what was in this jade box was indeed a pill formula.

After briefly reading the first sheet of paper, he turned the pages backward and looked at more than ten sheets in succession. He was pleasantly surprised to find that most of these pill formulas were Earth-Grade pill formulas, including the Cheng Wan Pill on the top sheet, there were actually seven of them.

However, when he thought that Ping Yaozi already had the ability to refine Dao Pills, he was relieved.

With these seven Earth-Grade pill formulas, plus the previous Tongyuan Pill and Chunlin Pill, he would not have to bother looking for pill formulas for a long time to come.

According to the descriptions of the properties and appearances of the pills in the pill formulas, Han Li basically confirmed that the bottle of yellow pills he had obtained from Ping Yaozi earlier was undoubtedly the Cheng Wan Pill.

In terms of grade, these pills seemed to be more superior than the Chunlin Pill. Of course, the spiritual herbs used were also not ordinary products. Not to mention that the varieties were rare, the main materials also needed to be over fifty to sixty thousand years old.

Fortunately, the Floating Mountain Secret Realm where Han Li was located was a natural treasure trove of spiritual herbs. Many spiritual herbs could be found here. With his status, the sect would naturally not question him if he only collected some spiritual herbs that were less than a hundred years old.

After that, he would use the Small Green Bottle to catalyze the main spiritual materials to the required age, and purchase the remaining spiritual materials with immortal essence stones as much as possible, it was only a matter of time.

Han Li suppressed the joy in his heart, picked up the jade box, and wanted to put these pill formulas back in place, when the corner of his eye suddenly caught a glimpse of something unusual at the bottom of the jade box.

He flipped his palm, took out a dagger as thin as a willow leaf, inserted it along the edge of the jade box, and gently pried it upwards.

There was a soft "ka" sound.

A smooth, mirror-like purple jade slab was pried up from the bottom of the jade box.

Han Li picked up the jade slab, which was not much thicker than a piece of paper, and looked at it carefully in front of him.

Through the firelight in the secret room, he could see that the seemingly smooth jade slab was covered with extremely fine and dense lines, which were connected to each other, outlining a very complex flower-like pattern.

Han Li closed his eyes, gathered his divine sense together, and probed towards the jade slab.

As soon as his divine sense touched the jade slab, the flower-like pattern on the slab immediately rippled with a layer of golden light, and golden runes flew out from it, directly bouncing his divine sense back.

After several attempts, it was always the same. He sighed softly and had to give up temporarily.

It was not that he could not use powerful divine sense to forcibly break it, but he vaguely felt that this jade slab seemed to have a lot of secrets, and he was unwilling to risk destroying the jade slab.

Helpless, he had to put the jade slab and the pill formulas back into the jade box and put it away again.

Then, he stroked in front of him again, and after a flash of light, a gray-white stone furnace more than one person tall appeared out of thin air and landed on the ground with a "dong" sound.
