He was really careful, but he still suffered a little loss.

Liu Zhen, on the other hand, was even worse. Not only was the fan torn apart by the ghosts, but a few other ghosts also lunged at Liu Zhen. They spat out Liu Zhen's head and face with a breath of death.

Liu Zhen's chubby face, which was originally fair and clean, was immediately affected by the Death Qi and turned black.

"Ah!" With a muffled cry, Liu Zhen immediately took a step back and meditated behind Xiao Yi, forcing out the Death Qi that was inhaled in his body.

Xiao Yi hurriedly cast a layer of True Energy shield in front of him, which shrouded both himself and Liu Zhen.

Judging from Liu Zhen's appearance, even though his cultivation wasn't low, he wasn't as experienced as Xiao Yi. He wouldn't be able to rely on him for the rest of the battle. With a thought, Xiao Yi summoned the three small swords.

Liu Zhen didn't expect that he would suffer such a great loss in a short time. While desperately expelling the Death Qi, he watched Xiao Yi's movements from the corner of his eyes. But he immediately felt downcast when he saw Xiao Yi release three small swords that couldn't even be regarded as Soul Weapons.

The three small swords, just like that, entered the Chillywind Skull Formation, and the ghosts all swarmed forward.

In the next second, Liu Zhen was dumbstruck. Those ghosts that could easily tear apart Soul Weapons had nothing to do with these three unremarkable wooden swords.

More than that, when the three small swords were taken out, there was a violent explosion. The three blazing flames instantly smashed several ghosts nearby, which were caught off guard. Some of the souls that had been tired were also burned to squeak.

In the blink of an eye, few ghosts had been taken care of.

"Hiss! What's this little sword made of? It's so strong!" Liu Zhen couldn't help but take a deep breath.

Naturally, he didn't know that Xiao Yi's small King Kong Wood swords, despite not being of a high grade, were made from King Kong Wood which was famous for its hardness. The hardness of the King Kong Wood had once caused even Xiao Yi to be helpless against it.

Seeing that several of the ghosts had been killed, Xiao Yi was also very happy.

However, when Xiao Yi used the Fire Explosion again, these ghosts had long possessed intelligence. When they saw the power of the King Kong Wood Sword's Fire Explosion, they all emitted an even stronger Death Qi. It was so strong that it was as if it was thick and solid. It was pitch-black and so thick that it could even squeeze the fire from the Fire Explosion together. It was unable to explode and could no longer cause harm to the ghost spirits.

Moreover, the explosion also aroused the fierce aura of the other ghosts. More than a hundred, wrapped in a strong death aura, unexpectedly rushed at Xiao Yi from the big formation, eager to devour Xiao Yi completely.

Xiao Yi also did not expect these ghosts to be so challenging to deal with. Seeing that the wooden swords could no longer play any role, he summoned back three small swords. Then, he patted the back of his head and released his double-coloured flying sword.

The golden and blue light was instantly filled with the small mountainside, and a surge of the sword will surged out.

The flying sword instantly grew to a few metres long, and like a giant dragon, it directly threw itself into the Chillywind Skull Formation.

Wherever it passed by, the extremely masculine and pure Golden Essence was like boiling water melting snow. It tore a hole in the thick Death Qi at once, and the ghosts screamed, it killed several of them.

A clear passageway appeared in the Chillywind Skull Formation. Xiao Yi even saw the original skeletons behind the formation.

It only managed to destroy those skeletons, and the Chillywind Skull Formation would naturally be destroyed.

Xiao Yi did not hesitate at all. With a surge of his True Energy, his flying sword flew toward the original skeletons in the formation.

However, the dark souls in the formation had already had spiritual intelligence. Naturally, it was impossible for them to let Xiao Yi's flying sword break the skeletons so easily. More than a hundred dark ghosts let out a ghost howl, making Xiao Yi's hair stand on end. Then, gusts of cold wind and the deadly Qi in the large formation rolled up like a pot rolling on the ground. The endless Death Qi kept coming from all directions, gradually forming a giant dragon of Death Qi. It rushed up from the big formation and directly blocked Xiao Yi's flying sword.

The strange thing was that a giant dragon that was condensed from the Death Qi of dozens of feet came sweeping over. It actually did not bring with it any signs of life. It just floated over in a chilly and quiet manner, as if it had frozen the air.

A gloomy, repressed, ruthless, and thoughtless tranquility aura filled the belly of this small mountain in an instant.

"I can't believe they actually have such moves!" Xiao Yi frowned. He calmed himself down, pinched his fingers, and mobilized his True Energy. Riding on his flying sword, he charged at the Death Qi Dragon.

"Bang..." The surging sword will and the Death Qi Dragon collided head-on with each other. The sound was not loud, but the whole mountain belly shook. If it weren't for the Spirit Seal Formation that had been set up in advance, the mountain would have already collapsed, and the ground would have been cracked.

After the collision between the flying sword and the Death Qi dragon, they were evenly matched. They were in a stalemate, and no one could move forward.

The ghosts exhaled mouthfuls of Death Qi on the Death Qi dragon, gathered all the power of the ghosts, and fought against Xiao Yi's flying sword.

Once the giant dragon formed by the Death Qi relaxed a little, Xiao Yi could break through the original skeletons and destroy the Chillywind Skull Formation with irresistible force.

Once Xiao Yi's True Energy ran out, the Death Qi dragon that chose to devour him would immediately make Xiao Yi suffer from the eternal pain of being devoured.

This life-and-death battle was in a stalemate.

In comparison, Xiao Yi was obviously at a disadvantage. The source of these ghosts was the Death Qi that gathered from all directions. Although it was not easy to gather them, the advantage was that they were endless. Xiao Yi relied on a mouthful of True Energy to contend against them.

Although Xiao Yi had reached the Foundation-building Realm and his True Energy was surging, he was still in a human body after all. If he continued to deliver True Energy like this, he would eventually run out of energy.

Obviously, those ghosts knew this, so they were not afraid of Xiao Yi. They looked at Xiao Yi with a sneer and waited for him to run out of his True Energy. Then they rushed forward and nibbled him clean.

As Xiao Yi's True Energy gradually decreased, Xiao Yi's double-coloured flying sword was finally forced to step back bit by bit by the Death Qi Dragon.

As soon as the ghosts saw the momentum, their killing intent became stronger. They twisted their bodies wildly and gathered the Death Qi under the ground, trying to overwhelm the last bit of Xiao Yi's True Energy.

Xiao Yi could even feel that the Death Qi under the ground, which had been silent for thousands of years, was absorbed by the Chillywind Skull Formation.

The pair of flying swords retreated little by little, and the blazing light around them was getting weaker and weaker under the corrosion of the Death Qi.

Xiao Yi felt that his True Energy was about to run out in his Elixir Field and frowned slightly.

The ghosts screeched as if they had seen the moment when Xiao Yi's bones were corroded by tens of thousands of souls. All of them had ferocious faces and looked extremely excited.

Seeing the sudden change of events, Liu Zhen was already shocked.

Seeing that Xiao Yi's flying sword was about to be swallowed up by the Death Qi Dragon, Liu Zhen's heart sank. He thought to himself, "This isn't good. Can it be that there's still danger of life in such a rash act of entering the belly of the mountain?"

However, when he looked at Xiao Yi again, his face looked the same as usual. He reached out and took out a small Yu Feiyan bottle from his bosom. Then he took out a milky-white pill.

As soon as the pill was taken out, it gave off a strange fragrance. Liu Zhen, who knew the way of deep-rooted pills, couldn't help but stare fiercely, "A sixth-level seventh-grade pill. My god, it's a sixth-level seventh-grade pill. What kind of pill is that? Why have I never seen it before?"

However, when he looked at Xiao Yi again, he had already opened his mouth and threw the pill into his mouth.

The pill was none other than the sixth-level Pill: the Jadeite Elixir!

As soon as the Jadeite Elixir was swallowed, it turned into a clear stream and fell into Xiao Yi's stomach. Xiao Yi only felt a heat flow rolling in his stomach, and his limbs and bones were in great pain. Then, his already exhausted abdomen was gradually filled with True Energy again.

This was precisely the effect of the Jadeite Elixir. It instantly replenished his True Energy. However, it consumed a lot of his body in the process of replenishing it. This was a forceful activation of his body's potential, turning it into True Energy so that he could make use of it for the moment. This was not something that should be done in the past.

However, the Jadeite Elixir was extremely powerful when it came to confronting the enemy in a real battle.

"Go!" How could Xiao Yi miss this opportunity? While his body was full of True Energy, he rushed out and injected it into the flying sword.

With the infusion of Xiao Yi's True Energy, the flying sword, which had lost its former brilliance, instantly became lively and leaping. With awe-inspiring sword intent and awe-inspiring might, it pressed toward the huge dragon formed by the Death Qi with unparalleled power.

The Death Qi Dragon was also struggling to withstand the attack. At this moment, Xiao Yi's flying sword's momentum soared. How could the Death Qi Dragon withstand it? In an instant, it was forced to retreat step by step by the flying sword.

On the side of the golden and blue flying sword, the Death Qi once again melted quickly like the spring snow. The flying swords oppressed the dragon and all the way toward the source of the evil wind formation. It went all the way to the skeletons. They could break through the formation by moving forward a little bit.

"Good heavens, could that pill be the Jadeite Elixir that can replenish one's True Energy in an instant? My God, did someone really refines the Jadeite Elixir in this world?" Liu Zhen was so shocked that he nearly forgot to get rid of the Deathly Qi in his body.

The ghosts in the formation were also extremely shocked when they saw this situation. However, a moment later, they actually did something that shocked Xiao Yi. The bodies of those dark souls were distorted, and the violent howls came one after another.

As the cries of agony rang out, the 108 skeletons started to burn silently and released wisps of frightening grey-white smoke. Eventually, this grey-white smoke gradually gathered on the death qi dragon bit by bit.

The Death Qi Dragon seemed to have been greatly revitalized. It immediately got rid of the previous situation of retreating and regained its power. In the twinkling of an eye, it trapped Xiao Yi's Flying Sword in a thick Death Qi.

The golden and blue flying swords, like insects that had fallen into the amber, could no longer move.

The light and spiritual power on the flying sword instantly dimmed.

The flying sword was connected to Xiao Yi's flesh and blood. For a moment, Xiao Yi's heart seemed to be blocked by something. He couldn't breathe and fell into a situation of life and death.

"This is bad. I've underestimated this Chillywind Skull Formation. If this continues for a short while, the flying sword will be eroded by this boundless Death Qi. At that time, everything will be too late." Xiao Yi thought quickly and was about to retreat.
