Having passed the first thirteen levels, Qin Xin's tense nerves were starting to feel tired.

The prolonged depletion of his spiritual sense left Qin Xin's eyes somewhat glazed. When dealing with the raging demonic bull, Qin Xin relied on his spiritual sense to discover its many weaknesses, concentrating dozens of crimson fire blades on a single point and bombarding it relentlessly, which was how he defeated it.

However, it was fortunate that the raging demonic bull was just a monster without any intelligence and did not know how to protect its weaknesses. Otherwise, the probability of Qin Xin defeating it would not be very high. Just its amazing defensive power would make it difficult for Qin Xin to break through.

On the fourteenth floor, Qin Xin was on edge.

Qin Xin felt that the difficulty of each level in the Spirit Realm would increase, but the monster that appeared on the fourteenth level was even weaker than the raging demon bull.

After quickly resolving the issue, Qin Xin sat down cross-legged.

~~~~~~

At this moment, outside the spiritual realm, the Eighth Elder suddenly opened his deep eyes and raised his head to look at where Qin Xin was.

His eyes were fixed on the fourteenth point of light that was slowly lighting up on the descending spiritual gate above Qin Xin's head, and there was a hint of disbelief in his eyes.

"The difficulty of the fifteenth floor is... ultimate!"

The Eighth Elder murmured to himself, clearly surprised by the sudden increase in difficulty for Qin Xin.

Some of the Kunmen disciples who were queuing up also heard the Eighth Elder's murmur and all turned their gazes toward Qin Xin, their eyes filled with surprise.

As the foundation of the inner courtyard of the Eastern Wilderness Academy, the Spirit Realm Space relies on this real combat to encourage disciples to continuously accumulate combat skills and quickly achieve breakthroughs under intense pressure.

Of course, the Spirit Realm will automatically set the difficulty based on the martial artist's strength and other factors. The higher the difficulty, the more spiritual energy one can obtain after passing through it.

This ultimate difficulty has always existed only in rumors, which is why the disciples reacted this way when the Eighth Elder uttered these words.

~~~~~~

Qin Xin, who was in the spiritual realm, was unaware of all this.

"Difficulty increased!"

After the sound rang out, Qin Xin frowned slightly, completely unaware of what had happened.

Amidst his confusion, a burning sensation suddenly enveloped his entire body, making Qin Xin feel somewhat suffocated.

After a single blue flame appeared, two more... then ten more...

The blue flames gathered together, turning into a sea of ​​fire, constantly surging with heat waves.

"What's going on?!"

Qin Xin wiped the sweat from his forehead and looked at the sea of ​​fire in front of him. He was a little flustered because he could feel that the Yang Fire Seed, which had been integrated into the Heavenly Phoenix Martial Spirit Pattern, was trembling slightly, as if it was very afraid of the blue flames.

The azure flame, however, seemed to covet the Yang Fire Seed within Qin Xin's body.

"Sizzle! Sizzle! Sizzle..."

Strange sounds emanated from within the blue sea of ​​fire, surrounding Qin Xin.

Under the scorching heat of the flames, Qin Xin had no way to escape. The Heavenly Phoenix Martial Spirit Pattern had already been activated to its limit, but the True Qi Gauze Cloth seemed to have no effect on heat insulation in the face of this blue sea of ​​fire.

"puff!"

A blue fireball suddenly burst out from the sea of ​​fire.

Seeing the blue sea of ​​fire launch an attack, Qin Xin dared not be careless and swung out the Nine Flames Battle Immortal Staff to try to disperse it.

"Hiss! What kind of flame is that?!"

The moment the cyan fireball touched the Nine Flames Battle Immortal Staff, it seemed to become attached to it, greedily devouring the orange flames on it.

It took Qin Xin a great deal of effort to peel off the blue fireball.

But the blue fireball had no intention of letting Qin Xin go, and followed closely behind him.

"Teacher, please help! What exactly is this flame?!"

A somewhat irritated voice kept calling out in Qin Xin's heart.

"You brat, what are you yelling about, disturbing my sweet dreams..." Danqing's somewhat displeased voice rang out, but before he could finish speaking, a questioning voice suddenly rang out, "This is... this is molten lava core fire!"

"Isn't it said that the lava core fire is born in the mountains, that it is red in color and shaped like a lotus? How could this blue fireball be a strange fire?"

Qin Xin objected to Danqing's words as he ran.

"You brat, I haven't finished speaking yet! This blue sea of ​​fire is just an attack tactic of the lava core fire. It's clear that the intelligence born from this lava core fire is quite clever, and it wants to devour your Yang Fire Seed."

Danqing's voice rang out, seemingly completely unfazed.

"Teacher, please think of a way to get rid of this blue fireball!"

Enduring the scorching flames and constantly fleeing, Qin Xin was also getting a little irritable.

"If it devours you, you can devour it too. You have yang fire, what are you afraid of!"

Danqing said with a hint of disappointment.

"Easier said than done. That's a strange fire, while my so-called yang fire is probably..."

Qin Xin was somewhat worried, after all, he knew the reputation of the strange fire, and he was afraid that his Yang fire alone was not enough.

"Forget it, you don't have a chance now."

As Danqing spoke, the azure sea of ​​fire seemed to encounter something and immediately retreated, quickly dissipating from the spiritual realm.

"It seems I guessed right, the molten core fire has been sealed by the Eastern Wilderness Academy."

"What a grand scheme! Aren't they afraid that the day this molten core fire breaks through, the entire Eastern Wilderness Academy will be buried with it?"

Danqing seemed to be able to see through the seal behind the spiritual realm.

"It seems I have no chance with the lava core fire."

Qin Xin curled his lip, after all, trying to snatch something from a behemoth that had stood in the Eastern Wilderness for countless years was simply impossible.

"Who says there's no chance! Judging from the ferocity of this strange fire, it will surely break through this spiritual realm within a year. At that time, the inner courtyard of the Eastern Wilderness Academy will probably turn into a sea of ​​fire!"

After Danqing finished speaking, he instructed Qin Xin to prepare the items needed to devour the strange fire, and then fell silent. It seemed that there was a powerful figure in the inner courtyard, and Danqing's frequent voices would expose his aura. He was able to speak earlier mainly because the aura of the strange fire was concealed.

As the blue sea of ​​fire faded, Qin Xin smoothly passed the fifteenth floor.

Qin Xin's ability to overcome this obstacle, given his current strength, was largely due to luck, as the appearance of the strange fire significantly impacted the spiritual realm.

As for the sixteenth floor, Qin Xin wanted to give it a try, so after the sea of ​​fire disappeared, he stayed in place and waited.
