Mortal: I became invincible after becoming sworn brothers with Han Li.

After Li Yunfan flew into the cave, he did not linger at all and went straight to the stone hall where the cold cave was located.

He leaped into the cave, simultaneously putting away the Cloud Piercing Boat, and immediately dashed towards a certain direction deep inside as soon as he landed.

Chan Fang, who was in pursuit, kept his divine sense locked on Li Yunfan's figure. When he saw Li Yunfan jump into the cold cave, he couldn't help but sneer in his heart and his escape light went straight into the cold cave.

Meanwhile, Li Yunfan, covered in sweat, was controlling the Ghost Shadow Six Demon Blades to form a sharp cone, desperately drilling into the icy ground where they were located. At the same time, he also attached the Yellow Spring Poison Fire to it so that it could break through the ice crystal more quickly.

Because of his Fire Spirit Body and the spiritual fire within him, he felt the cold very strongly.

Previously, when he subdued the Blue and White Spirit Flame, he discovered that the cold air in this place was the strongest and kept escaping outwards. Out of curiosity, he used his divine sense to probe the ground and unexpectedly found that there was a long passage connected below!

Due to the cold air, a thick layer of ice crystals had condensed on the inner walls of the passage. Moreover, the cold air became stronger the deeper one went. Even with the strength of his divine sense, he could only penetrate a little over a hundred feet before he could not continue to explore. The cold air was so intense that it seemed to freeze even the invisible divine sense into ice.

Although he didn't know where the passage led or whether he could withstand the intense chill, he was willing to take a gamble rather than surrender in the face of a mid-stage Core Formation cultivator's killing intent.

With the aid of the Yellow Spring Poison Fire, the Ghost Shadow Six Demon Blades broke through the ice at an extremely fast speed, and in just a short while, they had already reached a depth of one zhang.

"boom!"

A loud bang suddenly resounded inside the cold cave, and the ice crystals inside were shaken and smashed down.

Li Yunfan looked back anxiously, then cast a spell with both hands. His spiritual power surged out, and the Yellow Spring Poison Fire suddenly surged, increasing the speed at which it melted the ice crystals.

"Hurry up and get it through!!"

At this moment, he only had this one thought in his mind. Although he set up an array to block after entering, he was in such a hurry that he didn't have time to set up any complicated array. He could only take out a set at random and set it up.

Sensing that the formation was about to collapse, Li Yunfan raised his hand and waved it behind him, releasing the last four puppet beasts from his storage bag. With a thought, he issued a command, and the puppet beasts immediately ran to the formation, opening their mouths to emit white beams of light that shot towards Chan Fang, who was trying to break the formation.

Chan Fang raised his hand and released a protective spiritual shield, which blocked all the light pillar attacks, but he was also pushed back a few steps.

"You're about to die and you still want to struggle? Break it!" A fierce look flashed across his face. He made a hand seal and pointed at the formation. With a golden light, the formation exploded and disappeared with a "bang"!

However, this was not the end. A golden light flashed again, piercing and exploding all four puppet beasts before turning back to the Chan side. The light dissipated, revealing the true form.

It turned out to be a small golden sword, only a few inches long!

Then, Chan Fang opened his mouth and put the small sword into his body. This was a magic weapon that he had cultivated for hundreds of years.

As Li Yunfan was breaking the ice, he sensed that the formation had been broken, and his face suddenly turned deathly pale.

Just when he thought he was really going to die, the hard, thick ice crystals covering the passage were finally broken by him, and a gust of extremely cold wind blew out from inside, making him shiver involuntarily.

Just then, he felt a sudden tightness in his chest, as the other party's divine sense had locked onto him again!

Li Yunfan swiftly pulled out a bottle of pills, then jumped directly into the passage, simultaneously unleashing his Ice Spikes technique and bombarding the entrance.

In this extremely cold environment, the ice spikes created by the Ice Spikes spell were frozen together before they could even reach the entrance of the passage, solidifying into a single block of ice!

However, Li Yunfan was also in a very bad state at this time. In order to get out of the opponent's spiritual sense lock-on range as quickly as possible, he used his spiritual power to push him from behind while falling rapidly, which made his current falling speed no less than that of a Qi Refining cultivator flying with a magical artifact.

In this frigid air, falling at such a rapid speed, he didn't even have time to put the pill in his mouth before his entire body was frozen solid from head to toe!

Fortunately, he immediately controlled the flow of the Yellow Spring Poison Fire throughout his body to prevent the cold air from invading his body and freezing his flesh.

Chan Fang's divine sense had been locked onto Li Yunfan, so he naturally sensed that the other party was moving rapidly underground.

This made him frown, and with a swift movement, he arrived at the entrance of the passage. Upon seeing the white ice that had solidified inside, he raised his hand and unleashed his natal magic weapon, shattering it completely with a single strike!

Without the ice block to block it, the cold air surged out again, and even he was somewhat moved by the oppressive chill.

"So this icy cave was formed by the cold air gushing from this place!"

Suddenly, his expression changed, because his divine sense sensed that after Li Yunfan fell to a depth of 150 feet, it was blocked by that extremely cold energy and could no longer penetrate even a little bit.

"Consider yourself lucky you didn't die by my hand. It's just a pity about the monster materials he had..." After a few glances, Chan Fang finally gave up on jumping down the passage and turned to leave.

Inside the passage, Li Yunfan continued to fall at an extremely fast speed. Gradually, his spiritual energy was almost exhausted, and as his spiritual energy weakened, the Yellow Spring Poison Fire that permeated his entire body also slowly subsided.

Without the protection of the spiritual fire, the cold air began to invade his body, and the icy chill made his consciousness sluggish.

"Am I going to die...?" These were the last words Li Yunfan thought of before losing consciousness, after which he completely fell into a coma.

Gradually, Li Yunfan's blood became thick and sticky from the cold air, and his body became extremely stiff. If this continued, he would probably freeze to death in this cold air passage very soon.

The bone-chilling cold continued to penetrate his body. Just as the cold penetrated his flesh and blood and reached his bones, wisps of invisible red spiritual energy suddenly emanated from his bones. Unfazed by the icy cold, they traveled towards his dantian, seemingly with a purpose, and shot directly into the spiritual fire within.

The Yellow Spring Poison Fire floating in the dantian and the Purple Nether Heart Fire, still wrapped in blue and white spiritual fire, suddenly surged after absorbing the wisps of red spiritual energy, as if they had taken a powerful tonic!

Subsequently, without Li Yunfan's control, the two spiritual flames spontaneously burst forth from his dantian and began to circulate throughout his body, expelling all the invading cold energy...

After an unknown amount of time, Li Yunfan's eyelids twitched slightly, and he slowly opened his eyes.

"I'm not dead yet..."
