Approximately the time it takes for an incense stick to burn, Han Li and the others had gradually grown accustomed to the pain inflicted by the azure lightning. However, they each noticed that the black baleful aura seeping from their acupoints was not as dense as it had been initially, and its rate of emission had noticeably slowed.

Seeing this, Hu San and Shi Chuankong secretly breathed a sigh of relief.

Han Li, however, was not pleased but worried, his expression turning somewhat grave.

This was not a sign that the baleful aura within him was about to be completely cleansed, but rather that the efficacy of the azure thunder pool's baleful aura cleansing was waning.

"That's about enough. Each thunder pool is different, and the degree to which it cleanses baleful aura also varies. It seems that this azure thunder pool can only help you to this extent. Continuing further would only increase physical damage and have little effect," the voice of Old Ancestor Liu Qi rang out at the opportune moment.

"Senior, didn't you previously say that we could complete the baleful aura cleansing within this azure thunder pool?" Han Li asked, his brow furrowed.

"Who knew that you two little Gold Immortals would contain so much baleful aura? You must have countless souls on your hands from your path of cultivation," Old Ancestor Liu Qi said, curling his lip.

Han Li knew that what he said was true. With a leap, he was about to fly out.

However, as soon as he moved, the lightning beneath him immediately followed, covering his body like a thunderous electric net, entangling him tightly, and pulling him back into the thunder pool.

Hu San and Shi Chuankong tried briefly and found that it was the same for them, though seemingly slightly better than for Han Li.

With the baleful aura in their bodies not completely removed, the lightning in the thunder pool naturally continued to attack instinctively, preventing them from escaping.

Han Li's mind stirred, and the Mantra Treasure Wheel within him reversed rapidly. His figure shot out like a golden flash of lightning. On the other side, Shi Chuankong also used spatial secret techniques to escape.

Hu San, being the weakest physically, was the most severely injured of the three. Relying on his cultivation as a Grand Prime Jade Immortal, he was the last to escape.

After landing, the three stumbled, each taking the opportunity to sit down cross-legged.

Hu San was scorched black all over, with bloodstains all over his body, yet his face was filled with a joyful smile.

He turned his hand over and took out a fragrant Grand Prime-level pill, tossed it into his mouth, and swallowed it.

As the medicinal power unfolded, wisps of white gas rose from the bloodstains on his body, healing them at a rate visible to the naked eye.

On the other side, Shi Chuankong's expression was normal, but there was also a hint of joy in his eyes. He also took out a pill and swallowed it, and a large patch of black mist surged around him, enveloping his entire person.

Han Li's clothes were tattered, and the redness on his skin did not fade for a long time. Ti Hun stepped forward to ask, but he merely shook his head, indicating that he was fine.

He did not immediately take any pills but closed his eyes to adjust his breathing. He also carefully reviewed the fifth layer of the Refining Spirit Art, finding that he had indeed broken through the previous bottleneck and would soon be able to achieve great success with diligent practice.

Then, he also took several pills and silently refined their medicinal power.

Before even half an incense stick's worth of time had passed, Han Li and the others were awakened from their meditation by Old Ancestor Liu Qi.

"It's not that I'm unwilling to let you continue to recover, but time is of the essence. You trespassed into the Nine U族 forbidden area. Although Yin Chengquan may be unable to get away due to some Three Realms Alliance matter, it's hard to guarantee that he won't send others to come. By then, it will be difficult for you to continue cleansing your baleful aura," Old Ancestor Liu Qi said, his gaze sweeping over the three.

"That's right. Although there is no movement yet, the time left to us is indeed limited," Han Li said, nodding.

"San Sheng is already a Grand Prime Realm cultivator, so that's fine. The remaining baleful aura left in your two bodies is entrenched deeper within the immortal acupoints. Only by entering a more powerful purple thunder pool can it be cleansed. This will also take a lot of effort, so let's hurry up and continue," Old Ancestor Liu Qi said, his gaze falling on Han Li.

"Not so fast. According to the previously agreed upon, after the baleful aura is removed, we will help senior escape. Although the baleful aura has not yet been completely cleansed, we should first help senior cut off a chain to show our sincerity," Han Li said, naturally understanding the meaning hidden in his eyes.

"Since that's the case, then I'll trouble you," Old Ancestor Liu Qi said, a hint of satisfaction flashing in his eyes, as he nodded.

Shi Chuankong had no objection to this, and Hu San was even more pleased to see it happen.

"We just need the four of us to fully activate the Bloodthirst Blade, right?" Han Li asked, turning his hand over, a simple long blade appearing in his palm.

Old Ancestor Liu Qi's gaze swept over the long blade in Han Li's hand, a subtle, imperceptible color flashing across the depths of his eyes.

"Activating a Third-Grade Immortal Artifact to unleash its full power requires an extremely large amount of immortal spiritual power. I only hope that you will not hold back later, otherwise, if a single strike fails, it is very likely to provoke the backlash of the Thunderlock Chain. At that time, not only will I suffer great pain, but you may also be seriously injured," Old Ancestor Liu Qi said solemnly.

"This junior will naturally go all out," Hu San said, cupping his hands.

"Senior, rest assured, our interests are at stake, and this junior will not be foolish," Shi Chuankong also said.

Han Li did not speak, but simply nodded to Ti Hun.

After the four of them adjusted their breathing slightly, Han Li, holding the long blade, came to the forefront, with the other three standing behind him.

"Daoist Shi..." He lifted the Heavenfox Bloodthirst Blade, changing to a posture with both hands gripping it tightly. He was not in a hurry to activate it but tried to contact Shi Qinghou with his mind.

After waiting for a while, Shi Qinghou still seemed to be in a deep sleep, without the slightest response.

"Daoist Shi, I know that you must have some connection with this Old Ancestor Liu Qi, but regardless, at this critical moment, I still hope that you can lend me a hand," Han Li said with a mental connection.

Still, there was silence, without the slightest response.

Han Li frowned and stopped speaking. He gripped the Heavenfox Bloodthirst Blade tightly with both hands, light shining on his body. His immortal spiritual power began to flow continuously through his meridians and into the long blade in his hand.

A red light flashed on the blade, and all the patterns began to glow. A bloody aura spread from the blade.

Seeing this, Hu San and the others raised a palm each and pushed it towards the void. The immortal spiritual power in their bodies also spurted out, merging into Han Li's body and, through his hands, into the Heavenfox Bloodthirst Blade.

"Buzz..."

A slight trembling sound came from the blade. The long blade gripped tightly in Han Li's hands trembled constantly, shaking out layers of blood-red blade shadows, overlapping as if there were thousands of layers.

The aura released from the blade also climbed steadily, soon reaching an unprecedented level.

Han Li frowned, his heart also trembling with it. He felt as if his blood was also affected by the aura of the blade, and there was a strange feeling of boiling blood.

"This blade has a unique aura. It seems to have the effect of stimulating qi and blood, which can greatly increase the combat power of the user. You don't have to worry, just use your full strength," Old Ancestor Liu Qi reminded at this time.

Han Li secretly checked and found that there was indeed nothing unusual in his body before he began to fully inject immortal spiritual power into the blade.

As immortal spiritual power continued to merge, the blood light on the blade became more and more vivid, and the eyes of the two fox heads at the hilt also lit up with blood-red light. The whole blade gave off a completely different feeling.

Han Li's eyes narrowed, and he let out a violent shout, stepping forward and slashing down with the blade.

In an instant, countless huge blood-colored blade lights shot out from the void in layers, one after another, slashing down and falling on the azure chain.

"Clang, clang, clang..."

One after another sharp sounds of metal clashing rang out. The azure chain vibrated violently, and the runes engraved on it burst with azure light, like the explosion of a scorching sun!

"Rumble"

The azure thunder pool suddenly exploded, all the lightning surging up, turning into a huge spherical electric light, shooting towards Old Ancestor Liu Qi along the azure chain.

However, the spherical electric light traveled to the place where the blood-colored blade light fell and was intercepted by the blade light. The azure and red lights collided fiercely, and the two sides were deadlocked.

"Quick, cut it off!" Old Ancestor Liu Qi shouted violently.

Han Li and the others felt a violent shock all over their bodies, and the immortal spiritual power in their bodies poured out frantically as if out of control, continuously merging into the Heavenfox Bloodthirst Blade.

The blood light on the blade surged again, and the condensed blood-colored blade shadow seemed to have the weight of ten thousand jun, cutting down inch by inch towards the spherical lightning.

The expressions of Han Li and the others all changed. A sense of fear rose in their hearts. If this rate continued, before the chain was cut off, their immortal spiritual power would probably be looted first.

At this moment, the fox heads on the Heavenfox Bloodthirst Blade lit up, and a huge blood-colored fox shadow suddenly appeared, flashing in the void, making a pouncing gesture and falling downwards, merging into the blood-colored blade shadow.

The blood-colored blade shadow suddenly let out a roar, and it seemed to be transformed from illusion into a blood-colored crystal blade, slashing down.

With a loud "boom"!

The spherical lightning suddenly exploded, and countless azure electric lights shot out to the sides like two dazzling fireworks. A blood light flashed across in the middle, and the azure chain below broke in response.

"Clang clang clang..."

A sound of chains falling to the ground rang out, and the azure electric light retreated into the thunder pool and merged into it.

"It's done!" Hu San exclaimed with a happy expression.

Han Li frowned and retracted the long blade, carefully looking at it. He didn't understand why Shi Qinghou still chose to help at the last moment?

Shi Chuankong's eyes were deep, and he didn't say a word, obviously resentful of the sudden absorption of immortal spiritual power in his body before.

"What's wrong, Master?" Ti Hun came to Han Li and asked in a low voice.

"It's nothing. How is your injury recovery? Weren't you affected just now?" Han Li put away the Heavenfox Bloodthirst Blade and asked.

"No..." Ti Hun shook his head.

"Haha! Good, good!"

Old Ancestor Liu Qi raised his head, no longer in the lazy prostrate state he was in before. Looking at the section of azure chain that slid from his body, he burst into hearty laughter, shaking the entire giant hall slightly.

"Thank you, everyone. Please replenish your immortal spiritual power as soon as possible and continue to cleanse your baleful aura..." After laughing for a while, he spoke slowly.
