After Lin You Yuan and the other three of them managed to break through the Heaven and Earth Fog, they breathed a sigh of relief before a huge fireball flew towards them with a scorching heat.

Xun Yun felt the high temperature within the fireball and hurriedly warned the surrounding low-level disciples, "This is the Earth Core Flame, quickly disperse."

Instantly, the gathered cultivators all hastily scattered in all directions.

"Bang!" A loud sound was heard. The fireball exploded before the disciples could get even further away, and instantly, cries of agony rang out in the surroundings. Even many of the cultivators who had escaped were swept up by the spreading flames and turned into ashes before they could even let out a scream. The sky above the courtyard instantly turned into a purgatory as a sea of flames enveloped the entire sky.

"Damn it." They had never thought that the courtyard would actually hide such a move, and for the disciples of various sects that were above the Aurous Core stage, the losses for those that were at the Foundation Establishment stage or Qi Refining stage, aside from the disciples of the Cloudsoaring sect and the Cloud Sky Sect, had basically been completely wiped out. When they thought about how heavy the losses for those that were at the courtyard would be before they had even seen the disciples of the courtyard, their hearts did not feel well.

The fireball from before was already their last trump card, and this was even the ball of Core Flame that the founder of the academy had unintentionally subdued at the beginning of the academy. Now that they had reached the point of annihilation, they had no choice but to plant a heavenly thunder in this Core Flame and detonate it.

"All of the disciples of the Ganwu department, for the sake of the Ganwu department, come greet the enemy." After Wang Xu Xiang said this, he took the lead and flew up into the sky, thrusting his sword towards Xun Yun. When the other disciples saw that Wang Xu Xiang, as a Soul Formation cultivator, was actually the first to face the Four Sect Alliance, their morale immediately surged.

The Four Sect Alliance's side, however, was in a relatively chaotic state. Due to the effects of the fireball's explosion, many disciples were still looking at the sea of fire with lingering fear, and upon seeing many of the people who were alive right next to them being engulfed by the fire in the blink of an eye, the fear in their hearts immediately reached a high point, while their morale also dropped to a certain point.

Looking at the expressions of the disciples around them, Lin You Yuan and a few of them knew that they were in a bad state, and that they were not in a good mood either.

Xun Yun was about to say something when he felt Wang Xu closing in on him. He hastily took a step back to dodge Wang Xu Xiang's attack, and at the same time, he used his own magic treasure, the Demon Eye Hook, to block Wang Xu Xiang's next move.

"Wang Xu Xiang." Xun Yun coldly snorted.

Wang Xuxiang had failed in his first strike, so he retreated ten steps away from Xun Yun. "Wind Slasher." With a light shout, Wang Xu Xiang saw a white light directly cutting towards Xun Yun, and the space that the white light passed through clearly showed signs of being torn apart.

Although Xun Yun didn't value Wang Xu Xiang, he knew that he couldn't afford to be careless at this time. "Magic Light Barrier." Xun Yun used the Demon Eye Hook to draw a curved arc around his body. Following the Demon Eye Hook's movement, a black light appeared around his body, enveloping Xun Yun within it.

BOOM! The white light slashed into the black light barrier with a loud sound, but it was unable to take a step forward. Immediately, the white light and the light barrier formed a stalemate.

At the beginning, because many of the disciples were distracted, a few of them were injured. At this time, the remaining Nascent Soul stage disciples of the four sects woke up the disciples of the four sects and beheaded many of the disciples in the courtyard. This caused the surviving disciples of the four sects to reignite their fighting spirit.

"Fellow Daoist Lin, Fellow Daoist Lie, can you give the Flame Bomb to me?" Yun Tian said while looking at Lin You Yuan and Lie Zi with a faint smile. He looked at the battle-loving cells in the four directions and could not help but clamor. Just now, he had only saved the disciples of the Cloudsoaring sect and the Cloud Sky Sect from losing their members when he discovered that the fireball had exploded. But he knew that after this expedition, he would have to face the orders from both the Devil and the Intense Flaming Sect, so he needed a contribution to silence these two sects. And this was precisely the best reason for this.

"Since Fellow Daoist Yun has requested it like this, we can only give in." Lin You Yuan said with a smile.

When Raging Inferno saw Yun Tian take the initiative to hold the Flame Lightning, he did not say anything else. It was obvious that he was still dissatisfied with Yun Tian's earlier actions.

Yun Tian gave a faint smile before flying straight towards Huo Lei. He said to him, "Fellow Daoist Yan, look at the battlefield. It's already so chaotic. Can we fight in the air?"

Even though Yan Lei felt that Yun Tian had eyes, he could feel from Yun Tian's aura that the other party was also a mid stage Soul Formation cultivator. Even though he was a bit uneasy, he knew that what Yun Tian said made sense so he nodded and followed Yun Tian to the high altitude battlefield.

"Fellow Lie, we don't need to worry about Fellow Xun. Although it would damage our reputation to attack the younger generation, we can't stay idle in order to deal with him as soon as possible." Lin You Yuan raised his head and saw that Xun Yun had the upper hand between Xun Yun and Wang Xu Xiang.

Since he knew that Wang Xu Xiang was unable to fight against Xun Yun, he nodded and flew with Lin You Yuan towards the courtyard's Nascent Soul stage cultivators. Making a move against the Nascent Soul stage cultivators whose cultivations were lower than theirs was already their limit, and if they were to make a move against the Aurous Core stage cultivators, they would not be able to do so no matter what.

"Spatial imprisonment." The moment they arrived at the battlefield high up in the sky, Flame Lightning did not even have the time to activate her life magic treasure before she was immediately locked in place by Yun Tian.

Yun Tian looked down at the battlefield before turning his head towards Flame Lightning and said, "Fellow Daoist Yan, to be honest, you're not bad indeed, but it's a pity that you've met me." With that, Yun Tian immediately used the soul-searching technique on Flame Lightning. He obtained the information he needed, locking Flame Thunder in place before stealthily flying towards the treasury.

"Demon King's Hook." Xun Yun picked up the Demon Eye Hook and released a thick layer of black Qi. With a wave of his hand, the dense black Qi slowly turned into the head of an ox. The Infernal King picked up a hook and flew towards Wang Xu Xiang.

Wang Xuxiang hurriedly used his trenchant sword to block, "Jufeng!"

A silver blade slashed at the incoming Infernal King. The Ox Devil King let out a loud roar as he used the hook in his hand to strike the silver blade.

"Bang." With a crisp sound, the silver blade seemed to have its own consciousness as it avoided the hook in the Infernal King's hand and slashed at the hand of the Infernal King.

"Roar!" The Infernal King let out a painful cry. His severed arm emitted a thick black gas, but he immediately recovered. The Infernal King also seemed to be angered and slashed at the silver blade with a heavy hook.

"Crack." A crisp sound rang out as the silver dagger shattered into powder.

"Pfft." Wang Xu Xiang couldn't help but spit out a mouthful of blood. The Ox Devil King took the opportunity to fly in front of Wang Xu Xiang and slash at him. Wang Xu Xiang hastily used his Wave Severing Sword to block the attack.

However, Wang Xu Xiang didn't notice that Xun Yun had already teleported behind him, and while Wang Xu Xiang wasn't paying attention, Xun Yun had struck Wang Xu Xiang with his palm.

"Pfft." Wang Xu spat out another mouthful of blood, then looked at Xun Yun with disbelief and asked, "When did you do this?"

"Do you really think that the difference between the early and middle stage of Soul Formation is the difference between spiritual energy and the energy of heaven and earth?" Xun Yun disdainfully said.

Wang Xu Xiang recalled that Yan Lei had also once said that the difference between the early and middle stage of the Soul Formation stage wasn't simply spiritual energy, but at that time he didn't care. This time Xun Yun once again brought it up, which he couldn't help but care about.

Seeing the blank look on Wang Xu's face, Xun Yun didn't rush to kill him. Instead, he patiently explained, "When an early stage Soul Formation cultivator breaks through to the middle stage of the Soul Formation stage, they can refine an avatar. This avatar has the same aura as the main body, and the one you've been fighting with is only my avatar.

When Wang Xu Xiang heard Xun Yun's words, a trace of bitterness swelled up in his heart. His gaze became fierce and he wanted to self-destruct his primordial spirit, but no matter how much he thought of death, he could not make up his mind.

"Demon King's Bite." Xun Yun gave a low cry as he saw a ball of black Qi fly straight towards Wang Xu Xiang.

When Wang Xu Xiang reacted, he wanted to use the Absolute Wave Sword to block, but he found that the ball of black Qi had directly penetrated through the defense of his own Absolute Wave Sword. He hastily used his spiritual energy to create a protective barrier around his body, and was just about to heave a sigh of relief, but he discovered that the black Qi ignored his protective barrier and directly drilled into his own body.

"Ah!" Wang Xu Xiang clutched his hair and screamed in pain, struggling on the spot.

"My Devil King's Devour is not blocked by any spiritual energy and specializes in attacking the origin soul of Soul Formation cultivators. With your cultivation, there's no way for you to defend against it."

After Xun Yun finished speaking, he picked up the Demon Eye Hook in his hand and instantly cut Wang Xu Xiang's body into two halves. At this time, Wang Xu's primordial spirit revealed itself and continued to painfully hug his body in an attempt to stop the corrosion, but in the end, he could only watch helplessly as his primordial spirit was slowly corroded and finally disappeared from the world.

"If you had detonated your primordial spirit just now, it would have caused some damage to me. It's a pity that you're too afraid of death." After Xun Yun finished speaking, he turned around and left.

At this time, the other sects' battles had already ended. Lin You Yuan and Lie Zi were leisurely talking to each other while they tied Lan Feng up. The disciples of the various sects were on the side tidying up the battlefield and healing their wounds.

"Dao Friend Xun, since you are also finished, then the only thing left is …" Lin You Yuan hadn't even finished speaking when he heard a miserable scream. He saw Yan Lei's body fall down from the sky, and after twitching a few times, he stopped breathing.

"I've seen Fellow Daoist Yun and you're done." Intense said.

Yun Tian appeared behind Xun Yun with a faint smile and said, "Everyone is done watching this."

"Hmm, then the only thing left is …" Xun Yun said.

Their gazes all landed on Lan Feng. Just as they were about to say something, they heard a loud sound from the courtyard followed by flames that soared to the sky.

"This is …" The expressions of those people immediately turned ugly.

"It seems that from the very beginning, Yan Lei had already planned to not let anything from the Palace fall into our hands even if they were to die." Xun Yun said with cold eyes.

The others also had ugly looks on their faces. Lin You Yuan just directly killed Lan Feng. After all, they couldn't use Lan Feng anymore.

"Let's go." After Xun Yun finished speaking, he led the Devil Sect's men away. Lin You Yuan and the others also left with the disciples of the various sects.

No one noticed the faint smile on the corner of Yun Tian's mouth.
