The dark figure let out a shrill roar, actually withstanding the attack; the black mist only dimmed slightly.

"Is the strength of a Celestial Master really that strong?" Leng Muya's face turned pale. Her Heavenly Thunder Formation was capable of killing beings at the Ghost King level.

Upon seeing this, Zhao Yuntian immediately formed a hand seal: "Seven Star Sword Formation!"

The flying swords transformed into seven magical swords that formed the Big Dipper formation in the air, and the sword light fell like rain.

The demon spirit was trapped by the sword formation. The black mist was constantly being cut away by the sword energy, but it quickly regenerated.

"It's absorbing the yin energy inside the cave!" Lin Yao suddenly noticed something. "We must cut off its supply!"

As she spoke, she took out the last three spirit-suppressing talismans from her bosom, bit her tongue, and spat a mouthful of blood onto the talismans: "Seal!"

The three talismans transformed into golden light and disappeared into the ground, causing the flow of yin energy in the entire cave to stagnate.

The demon's movements visibly faltered, and its regeneration speed decreased significantly.

The demon spirit was trapped by the double array, and its bloodthirsty aura was constantly disappearing. Unable to be replenished, it let out a shrill roar, and its black mist-like body twisted and deformed in an attempt to break free from the shackles of the array.

A chilling wind howled inside the cave, pebbles fell in a rustling sound, and the entire space trembled.

"It's going all out!" Lin Yao formed hand seals, and a golden light shot into the Heavenly Thunder Formation. "I'll reinforce the formation!"

Zhao Yuntian changed his sword technique, and his flying sword transformed into seven sword shadows, which pinned down around the demon spirit: "Seven Star Soul Lock".

The sword's edge pointed directly at the source of the demonic spirit: "Suppress!"

The demon spirit let out a piercing shriek, and a distorted human face suddenly materialized in the black mist, with a pair of blood-red eyes, as well as black nostrils and a mouth.

The mouth opened and closed, uttering a voice: "You mere ant, how dare you obstruct me?"

The sound was like the roar of millions of people at the same time, making everyone's eardrums ache.

Rong Jiaojiao felt a sharp pain in her mind and almost lost her balance.

Zi Ling collapsed to the ground, and Rong Jiaojiao quickly put it into her spirit beast pouch.

"Oh no, it's attacking with sonic waves!" Leng Muya's face turned pale, and a trickle of blood seeped from the corner of her mouth.

Seizing the moment when everyone was distracted, the demon spirit suddenly expanded the black mist, and the Heavenly Thunder Array made a "crack" sound as it was about to break under the strain!

"Pfft—" Leng Muya, who was in charge of the formation, spat out a mouthful of blood and swayed.

At the critical moment, Lin Yao pricked her finger and drew a blood talisman in the air: "With my lifeblood, I summon the divine thunder of the nine heavens!"

The blood talisman transformed into a beam of red light that shot straight to the top of the cave. With a deafening roar, a bolt of purple lightning as thick as a bucket pierced through the mountain and struck the demon spirit directly!

\"roar--!\"

The demon spirit let out an unprecedented roar, and most of the black mist was cleaved apart.

But it didn't dissipate; instead, it became even more ferocious: "You will all die!"

The remaining black mist suddenly contracted, transforming into a jet-black spear that pierced towards Lin Yao with lightning speed!

Everyone tried to use magic to stop the spear, but it was too late.

Just as the black spear was about to pierce Lin Yao's chest, a golden light suddenly burst forth from her bosom—it was the protective jade pendant that she always carried with her!

The golden light collided with the black spear, creating a deafening explosion.

Lin Yao was thrown back by the shockwave and crashed heavily into the stone wall, blood trickling from the corner of her mouth, but she managed to save her life.

The demon's attack seemed to have exhausted its power, and the black mist became thin and transparent.

Zhao Yuntian seized the opportunity, his flying sword slashing down with the force of a thunderbolt: "Destroy!"

Where the sword light passed, the demonic spirit almost completely dissipated, leaving only its core essence.

The demon spirit, having run out of energy, could only charge left and right. Leng Muya immediately threw out a Soul-Destroying Talisman to slowly erode the demon spirit's spirit.

Rong Jiaojiao felt a pang of regret looking at the ethereal spirit of the Celestial Master realm demon. She thought that if she had the ability to trap it, purify it, and then refine and absorb it, she would definitely be able to increase her divine sense power considerably.

Thinking this, everyone felt a spatial fluctuation, and the trapped demon spirits vanished without a trace.

Everyone exclaimed, "Damn it, the demon spirit's spirit has escaped!"

Rong Jiaojiao was shocked. She had a feeling that the secret realm was behind it.

As his consciousness sank into the small secret realm, he saw the demonic spirit Lingmei trapped beside the small tree in the center.

Su Yuqing asked in confusion, "How did it escape?"

Rong Jiaojiao dared not show anything unusual, so she quickly put on the same expression as Su Yuqing and the others, looking at Zhao Yuntian, Lin Yao, and Leng Muya with a confused expression.

They hoped to learn from them why the demon had escaped.

The group cautiously looked around, their divine senses sweeping across the entire cave like a tidal wave, but they could no longer find any trace of the demonic spirit.

“Strange…” Zhao Yuntian frowned. “It was clearly weakened to its limit, how could it just disappear into thin air?”

Leng Muya wiped the blood from the corner of her mouth and said in a deep voice, "Unless... it has a backup plan, or someone is there to help it."

Lin Yao stood up, clutching her chest, her face pale, but her voice was firm: "The demon spirit is extremely cunning; we must not let it escape, or the consequences will be dire!"

Rong Jiaojiao's heart raced, fearing that the secret of the little secret realm would be discovered, and she quickly chimed in, "Could it be that it used some kind of spatial escape technique?"

“Spatial escape technique?” Zhao Yuntian pondered for a moment, then shook his head and said, “A demonic spirit at the Celestial Master level may indeed possess some spatial abilities, but the fluctuation just now was very weak, it doesn’t seem like it cast the spell itself.”

Su Yuqing frowned: "Could it be... that there are other evil cultivators here?"

Upon hearing this, everyone immediately became alert, summoning their magical artifacts and scanning their surroundings with their divine senses once again.

Rong Jiaojiao secretly breathed a sigh of relief; it seemed that no one suspected her.

She secretly sensed the small secret realm and discovered that the demonic spirit was bound by the spiritual light emanating from the small secret realm and could not move.

"Never mind how it escaped," Leng Muya said coldly. "The most urgent task is to dispel the bloodlust and yin energy here and prevent this place from being used by others again."

“Yes.” Zhao Yuntian nodded. “This place is not safe to stay for long. We should leave as soon as possible.”

The group quickly cleaned up the battlefield, destroyed the altar, and dispelled the foul odor. After confirming that nothing was left behind, they left the cave with the unconscious children.

It was late at night when Zhao Yuntian led everyone back to the inspection team. Leng Muya arranged for everyone to rest, and she settled the children before going to rest herself.

Back in her room, Rong Jiaojiao first restored her spiritual power before immersing her consciousness into the small secret realm.

Around the sapling, the demonic spirit still emitted wisps of bloodthirsty aura.

With a thought, a mid-level exorcism talisman and a mid-level purification talisman were stuck onto the demon spirit.

The wisps of bloodthirsty energy were purified, but the spiritual energy was far too powerful, and Rong Jiaojiao estimated that it would take quite some time to completely purify it.

The next day, when Rong Jiaojiao woke up, Zhao Yuntian and Lin Yao had already left, and the seven children had been taken back by the police.

The police later announced that the children were missing, citing that they had been abducted by human traffickers.

Leng Muya was seriously injured this time and took several days to recover before emerging from seclusion. Upon her return, she immediately summoned Rong Jiaojiao.
