Before long, they had flown to the outer edge of Tianming Cave, a square cave suspended in the air surrounded by a powerful barrier that could withstand the lightning of the heavens.

It is somewhat similar to the cave dwelling of the Mercury Immortal.

At the entrance, there is a gate and a long staircase leading to it.

There were two guards under the archway.

"Who goes there?!"

The two guards clearly realized that Guo Feng and his group were not on their side. They shouted questions while taking out a communication talisman to warn the people inside the cave.

"The people who came to kill you."

Guo Feng's voice carried faintly, and then the Hidden Dragon Immortal Sword shot out, instantly piercing through the barrier, and two sword energies pierced through the two guards.

Bang bang...

Before the communication talisman could even be activated, the two True Immortal Realm guards were instantly blasted apart by the sword energy.

Swish!

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

Guo Feng reached out and caught the communication talisman.

Then, he waved his hand and said, "Let's go inside."

Without lingering, they entered the entrance to the cave.

The interior of this grotto is similar to that of the Mercury Immortal's grotto, forming its own world. However, inside are landmasses floating in the sea of ​​clouds, giving it a distinctly celestial appearance.

Their entry also attracted the attention of the patrolling guards inside the cave.

"Enemy invasion!"

Several guards shouted in alarm, but before their voices could be heard, they were killed by several sword strikes.

"Who dares to be so audacious!"

Just then, a roar came from a piece of land in the cave.

Then, dozens of figures flew out.

Leading the group was an elderly man with white hair, a seventh-rank Xuanxian, with several other Xuanxian by his side.

They were aggressive and roared repeatedly.

"It's the Grand Elder's Zen style!"

Nine-Tailed Red Spirit, who was quite familiar with this cave, quickly spoke to Guo Feng.

Guo Feng nodded: "According to the previous plan, it's handed over to you."

Swish—

With a wave of his hand, a vortex appeared, and Sima Han and the others were summoned out from the first level of the Haotian Realm.

The idea flashed through his mind, and he relayed the plan to Sima Han, then said, "Go!"

"yes!"

Sima Han and the others nodded hurriedly and immediately shouted, "Form ranks and charge!"

"Mars, you and I will slay that Elder Chanfeng together!"

Without hesitation, Yuexing charged towards Zenfeng.

Having previously obtained Guo Feng's elixir, his strength had greatly increased, and he was not afraid at all when facing a seventh-grade Xuanxian.

Mars did the same, immediately activating its magical artifact and rushing off with the Moon.

The leaders of the twelve families, including Sima Han, also obtained the elixir. Sima Han, for example, had already broken through to the second-grade Xuanxian, while some tenth-grade and ninth-grade Tianxian also comprehended the profound meaning and broke through to the Xuanxian.

Therefore, with their strength greatly increased and leading more than four hundred powerful warriors, it would not be a problem for them to surround and kill other Xuanxian and Tianxian.

The formation solidified, and a fierce battle ensued, causing precious light to radiate and sword energy to soar into the sky.

"Immortal Tianming, stop your seclusion and come out to die!"

Guo Feng's voice echoed in the sky above Tianming Cave.

"court death!"

A deep, resonant voice then rang out.

With a loud bang.

A palace on the central landmass suddenly exploded, and a dark figure rushed out.

Sizzle—

Without saying much, the opponent transformed into a sword, becoming one with the sword, and unleashed a terrifying sword aura that instantly struck Guo Feng.

The sword energy of a ninth-rank immortal is enough to annihilate all the weak.

"Wow, that's impressive! Luckily I was prepared!"

Guo Feng felt a sense of suffocation. He realized that with his own cultivation level alone, he was probably no match for a ninth-grade Xuanxian.

Fortunately, he didn't need to rely on his own strength to deal with this ninth-grade Xuanxian.

With a thought, a surge of abyssal demonic energy condensed into an abyssal array, blocking his way.

Rumble...

This abyssal demonic energy is a supreme demonic energy at the core of the Heavenly Demon Tomb, far surpassing the demonic energy of the seventy-two Heavenly Demon Emperor tombs.

As soon as the great formation was activated, the sword energy of the ninth-grade Xuanxian was cut into the formation, just like being cut into an abyss, and disappeared without a trace.

"What?!"

A dignified middle-aged man, wearing a jade crown and with a tall and straight figure, was none other than the Celestial Immortal Tianming.

A legendary swordsman who roamed the Nine Heavens Thunderclouds of the Spirit Realm of the capital.

His cultivation level reached the ninth rank of Xuanxian.

He has collected seven famous swords from all over the world, five of which are renowned ancient spirit swords.

The other two are low-grade immortal swords passed down from an ancient cave.

He had just become one with his sword, unleashing a sword aura several kilometers long, which contained a killing intent.

But to everyone's surprise, it was silently blocked by a demonic array.

He glanced at the fierce battle around him, then looked coldly at Guo Feng, "Who are you? Why are you leading people to attack my Tianming Cave Heaven?"

"If your people invade my territory, of course I'll fight you back."

Guo Feng smiled faintly, "I know you have extremely strong swordsmanship and are a famous sword immortal. Then let me test your swordsmanship against you!"

Without wasting words, he waved his hand and the Heaven-Slaying Sword Formation Diagram shot out.

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

There were actually six mid-grade immortal swords!

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

The Heaven-Slaying Sword Formation Diagram instantly condensed boundless sword energy, transforming into six long sword energy dragons that soared into the sky.

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

Immortal Tianming was extremely surprised. It had taken him thousands of years and countless near-death experiences to collect all seven famous swords, of which only two were low-grade immortal swords.

Guo Feng's move was terrifying from the very first strike.

He couldn't believe it. Could it be that a powerful second-generation expert from the Nine Heavens Immortal Realm had descended upon the land?

That's impossible!

The Nine Heavens Immortal Realm has long been sealed off, so it's impossible for anyone to descend to the mortal realm!

Immediately, his gaze sharpened, and he sneered, "So what if you have six mid-grade immortal swords? With just a sword formation diagram and your strength as a ninth-grade true immortal, how can you fight me?"

"Seven Swords, Shatter the Heavens!"

With a roar, seven dazzling sword beams flew up behind him, displaying seven different kinds of light. Six of these beams clashed with the six sword energy dragons of Guo Feng's Heaven-Slaying Sword Formation.

The momentum is fierce!

The moment the two sides made contact, a deafening explosion occurred, the sword energy was annihilated, and the aftershocks caused a frenzied impact.

The other attack, however, was aimed directly at Guo Feng.

This sword beam is the true killing move of this technique, extremely fierce. It is an ancient low-grade immortal sword with extremely strong destructive power, containing nine-tenths of the Xuanxian power of the Heavenly Immortal.

It came crashing down in an instant.

Guo Feng felt suffocated.

However, Guo Feng clenched his fists, merging the divine talisman in his left hand and the Great Heavenly Demon Void Array of the Heavenly Demon Tomb in his right.

Then, he threw out both fists simultaneously, unleashing the unparalleled martial art of the Great Sumeru Divine Fist against the sword light...
