551: Fight against the ninth-grade Xuanxian!

Not long after, they had already flown to the periphery of Tianming Grotto-heaven, a square grotto-heaven suspended in the air, surrounded by a powerful barrier that resisted the Nine Heavens Thundercloud Layer.

It was somewhat similar to Water Star Great Immortal's previous dwelling.

Only at the entrance was there an archway with a long flight of stairs extending from it.

Under the archway were two guards.

"Who goes there?!"

The two guards clearly saw that Guo Feng and his companions were not their own people. While shouting loudly, they took out a communication talisman, preparing to alert the people inside the Grotto-heaven.

"The one who came to kill you."

Guo Feng's voice drifted over faintly, and then the Qianlong Immortal Sword shot out, instantly piercing through the barrier. Two streaks of sword qi immediately pierced through the two guards.

Bang bang...

Before the communication talisman could be crushed, the two True Immortal realm guards were directly blown apart by the sword qi.

Swish swish!

The next moment, Guo Feng and the other three had already passed through the barrier and landed under the archway.

Guo Feng reached out and snatched the communication talisman.

Then, he waved his hand, "Let's go, enter."

Afterward, without any delay, they entered the entrance of the Grotto-heaven.

The interior of this Grotto-heaven was similar to Water Star Great Immortal's Grotto-heaven, forming its own world. However, inside were lands suspended in a sea of clouds, appearing to possess a celestial demeanor.

After they entered, they also attracted the attention of the patrolling guards within the Grotto-heaven.

"Enemy invasion!"

Several guards hurriedly shouted, but before their voices could spread, they were already annihilated by several streaks of sword qi.

"Who dares to be so audacious!"

Just then, a roar came from a piece of land within the Grotto-heaven.

Subsequently, dozens of figures flew out.

Leading them was a white-haired old man, a Seven-Rank Mysterious Immortal, accompanied by several other Mysterious Immortals.

They were aggressive, roaring repeatedly.

"It's the Great Elder Zen Feng!"

Nine-tailed Red Fox, who was more familiar with this Grotto-heaven, quickly said to Guo Feng.

Guo Feng nodded, "According to the previous plan, I'll leave it to you all."

Swish—

He waved his hand, and a vortex appeared. Sima Han and the others were called out from the first layer of the Haotian Realm by him.

With a thought, he transmitted the plan to Sima Han and then said, "Attack!"

"Yes!"

Sima Han and the others quickly nodded and immediately shouted, "Form ranks, kill the enemy!"

"Mars, you and I will kill that Great Elder Zen Feng!"

Moon also did not hesitate and immediately charged towards Zen Feng.

He had previously obtained Guo Feng's immortal pills, greatly increasing his strength, and facing a Seven-Rank Mysterious Immortal, he was not afraid at all.

Mars was the same, immediately activating his magic treasure and rushing forward with Moon.

As for Sima Han and the people from the twelve families, their leaders had also received immortal pills. For example, Sima Han had already broken through to a Second-Rank Mysterious Immortal, while some Tenth Grade Celestial Immortals and Ninth Grade Heavenly Immortals also took the opportunity to comprehend profound meaning and break through to Mysterious Immortals.

Therefore, with their greatly increased strength and leading over four hundred strong cultivators, it was no problem to encircle and kill other Mysterious Immortals and Celestial Immortals.

The formation condensed, and immediately, a fierce battle erupted with the opposing side, causing treasure light to overflow and sword qi to soar into the sky.

"Heavenly Meditation Celestial, stop your seclusion and come out to die!"

Guo Feng's voice echoed above Tianming Grotto-heaven.

"Courting death!"

A deep voice immediately resounded.

With a bang.

A palace on the central land suddenly exploded, and a black figure rushed out from within.

Rip—

With hardly any words, the opponent had already transformed his body into a sword, man and sword as one, unleashing a terrifying sword qi that, in the blink of an eye, had already struck before Guo Feng.

The sword qi of a Nine Rank Profound Immortal was enough to annihilate all weaker individuals.

"So strong, fortunately, I was prepared!"

Guo Feng even felt a hint of suffocation. He felt that relying solely on his cultivation power, he probably wouldn't be a match for a Nine Rank Profound Immortal.

Fortunately, he didn't need to rely on his own strength to deal with this Nine Rank Profound Immortal.

With a thought, a surging Abyssal Devil Qi condensed into an Abyssal Grand Formation, blocking in front of him.

Rumble...

This Abyssal Devil Qi was a supreme devil qi from the core of the Tian Mo Tomb, its quality far surpassing the devil qi of the Seventy-two Heavenly Devil Emperor Tombs.

As soon as the grand formation appeared, the Nine Rank Profound Immortal's sword qi, when it struck the grand formation, was like striking into an abyss, disappearing without a trace.

"What?!"

A distinguished middle-aged man, wearing a jade crown and with a tall, upright figure, was none other than Heavenly Meditation Celestial.

A generation of Sword Immortals who roamed the Nine Heavens Thundercloud Layer of the Jinghua Spirit Realm.

His cultivation had reached Nine Rank Profound Immortal.

He had collected seven famous swords of the world, five of which were famous excellent-grade spirit swords from ancient times.

The other two were low-grade immortal swords passed down from ancient cave dwellings.

Just now, he had merged with his sword, unleashing a sword qi several kilometers long, containing a murderous intent.

But he never expected it to be silently blocked by a demonic grand formation.

He glanced at the fierce battle around him, then looked coldly at Guo Feng, "Who are you, sir? Why did you bring people to attack my Tianming Grotto-heaven?"

"Your people attacked my territory, so of course, I must attack you."

Guo Feng smiled faintly, "I know your swordsmanship is extremely strong, and you are a famous Sword Immortal. Then let me meet you with swordsmanship!"

He didn't waste any words. As he spoke, he waved his hand, and the Heaven Severing Sword Formation Diagram shot out.

At the same time, six extremely dazzling rays of light instantly merged into the Heaven Severing Sword Formation Diagram.

They were actually six mid-grade immortal swords!

In an instant, surging sword qi and sword intent filled the entire world.

The Heaven Severing Sword Formation Diagram immediately condensed endless sword qi, transforming into six long sword dragons that soared into the sky.

"What? Six mid-grade immortal swords? Who exactly are you? How can you gather six mid-grade immortal swords?"

Heavenly Meditation Celestial was extremely surprised. It took him thousands of years and numerous near-death experiences to collect seven famous swords, and among them, only two were low-grade immortal swords.

Guo Feng's first move was so terrifying.

He found it hard to imagine. Could it be that a second-generation powerhouse from the Nine Heavens Immortal Realm had descended?

But that was impossible!

The Nine Heavens Immortal Realm had long been sealed off; it was impossible for anyone to descend to the lower realms anymore!

Immediately, his gaze sharpened, and he sneered, "So what if you have six mid-grade immortal swords? How can you fight me with just a sword formation diagram and your Ninth Grade True Immortal strength?"

"Seven Swords, Heaven Breaking!"

He roared, and seven dazzling sword lights flew up behind him, displaying seven different colors. Six of these lights intertwined with the six long sword dragons of Guo Feng's Heaven Severing Sword Formation Diagram.

Their momentum was fierce!

As soon as the two sides met, earth-shattering explosions erupted, sword qi was annihilated, and the aftershocks violently impacted.

The other sword light, however, directly struck towards Guo Feng.

This sword light was the true killing move of this technique, extremely fierce. It was an ancient low-grade immortal sword, incredibly destructive, and contained ninety percent of Heavenly Meditation Celestial's Mysterious Immortal power.

It pierced through with a single strike.

Guo Feng even felt suffocated.

However, Guo Feng clenched his fists, integrating a divine talisman into his left hand and the Great Heavenly Demon Nihility Grand Formation of the Tian Mo Tomb into his right hand.

Then, he unleashed both fists simultaneously, striking out the peerless martial art of the Great Sumeru Divine Fist against this sword light...
