After a few steps, Xu Wen suddenly felt a chill.
It is already late spring and early summer. In this season, the underground temperature must be lower than the ground temperature, but it won't drop so fast, right?
Confused, he couldn't help but quicken his pace.
The further inside, the faster the temperature dropped, and eventually it turned into a strange coldness that penetrated the bone marrow and soul.
There was a crackling sound, Xu Wen raised his breath sharply, hooked the barb on the top of the stone crevice, looked forward, and suddenly took a breath of cold air.
A strange formation was built here using thunder stones. A dozen ghosts with vague silhouettes were trapped in the center of the formation. From time to time, tiny lightning bolts were drawn out and struck at the ghosts, causing them to scream in agony.
When Xu asked, he happened to see a ghost being destroyed by lightning, but the figures of those ghosts that survived were obviously much more solid.
"The yin and yang are born, these ghosts are using lightning to reshape their ghost bodies?"
Xu Wen was extremely surprised. He didn't know much about ghost cultivators and didn't know they had such a method.
No wonder all the thunder stones have disappeared, they were all brought here.
That formation is also very strange. It can actually draw out the remaining thunder and lightning power in the thunder stone, and it can also control the intensity.
Ghosts are very afraid of thunder and lightning. If the thunder and lightning released were stronger, these ghosts would probably be destroyed.
Just as he was carefully observing the thunder stone formation, a white shadow suddenly appeared and emerged from the stone wall behind him.
Unlike other illusory ghosts, the white ghost's figure is very solid, and his face can even be seen clearly.
The most amazing thing is that there is no trace of ghost energy in his body. If it weren't for his erratic figure, he would be almost like a living person.
After observing for a long time, he suddenly and silently pounced.
Xu Wen, who was concentrating on studying the secrets of the Thunder Stone Formation, suddenly felt a chill on the back of his neck, and a cold breath rushed into his meridians, reaching towards his Dantian.
This breath is extremely strange. Wherever it goes, the magic power is instantly imprisoned and cannot be controlled at all.
Terrified, his mana surged and he tried his best to resist the cold air.
The white ghost was also very surprised. Although this human being had low magic power, he had extremely strong energy in his body.
He couldn't feel it without touching it, but after touching it with his own hands, the steaming blood seemed to dissipate his ghost body.
The situation that was originally certain and easily controllable turned into a stalemate.
How did he know that Xu Wen has been eating black pearl rice these days, and his vitality is not inferior to that of the monks in the late stage of Qi refining.
Although he tried his best to resist, the cold air was still approaching the dantian step by step. Once the dantian was controlled, life and death would inevitably be in the hands of others, and he would no longer be able to resist.
With his heart pounding, Xu Wen suddenly bit the tip of his tongue, shouted angrily, and sprayed a mouthful of blood onto the ink jade ring.
The black jade ring is a treasure of blood sacrifice, and it can be driven with the help of a small amount of magic power in the blood. As soon as he thought about it, the Buddha's Ghost Refining Banner quietly appeared and fell into his hands.
The flags turned on their own without any wind, and the evil ghost roared and jumped out suddenly.
But as soon as he saw the white ghost, he screamed in horror, turned around and ran away.
Xu Wen was already used to this scene. The evil ghost had always been a coward who bullied the weak and feared the strong. He was completely different from other brainless ghosts and was very cunning.
But after basically repairing the flag, he gained a deeper and deeper grasp of this magical weapon, and the evil spirits could not even think of escaping from his control.
The flags were pressed heavily, and the mind poured in, turning into a silent command:
"Coward, get on me!"
The Buddha's Ghost Refining Flag suddenly erupted with golden light. Under the invisible restraint, the evil ghost screamed again and again, but still couldn't help but pounce on the white ghost.
At the moment of contact, black smoke suddenly rose from the two ghosts. They screamed and backed away, and their figures became lighter.
The two ghosts are actually each other's nemesis. When they come into contact, they are like fire and water, and one of them must melt away.
The white shadow left, and Xu Wen was immediately free. He turned around suddenly, looked at the strange white shadow, and without saying a word, he shook the Buddha and Ghost Refining Flag again and again.
The flagpole made an overwhelming "squeaking" sound, and seemed to be broken at any time, but facing this strange and unpredictable white ghost, he couldn't care about anything at the moment.
Black smoke was still rising from the evil ghost's body, and he was wailing and fleeing in the distance. However, the Buddha's Demonic Banner had a strong control over him, and his irresistible will came over him. He could only scream in fear while walking around. He couldn't help but save again.
The white ghost was trying his best to dispel the strange power in his body. He didn't expect that the other party would pounce on him so desperately. He couldn't avoid it and was immediately haunted by the evil ghost again.
Before the two ghosts separated, Xu Wen shouted angrily and poured all his magic power into the Buddha's Ghost Refining Flag.
Dots of golden light flew out, laying down a golden array around the entangled two ghosts.
The golden light shone like water waves in the sun, and was squeezed in from all directions. The two ghosts were unable to escape, and they were immediately close to each other, mouth to mouth, face to face.
Amidst the weird screams, black smoke rose from the place where the two ghosts came into contact.
This thing was actually transformed by the ghost's vitality. Under the offset of yin and yang, the shadows of both ghosts began to dim rapidly.
Both ghosts kept wailing in fear, but they were pressed together by the formation. This battle would only end if one side was completely exhausted.
Looking at the two ghosts who were forced to die together, Xu Wen was also secretly frightened, fearing that the evil ghosts would not be able to defeat the white ghosts. In that case, the Buddha's Ghost Refining Flag would be completely useless.
However, the origin of the evil ghost is obviously extremely extraordinary. Although he behaves very badly when facing the white ghost, when it comes to real consumption, his endurance is far superior to that of the white ghost.
The body of the white ghost melted much faster than that of the evil ghost. A moment later, with a scream of fear, the last shadow of the white ghost turned into a puff of blue smoke and disappeared completely.
Looking at the evil ghost again, he is much weaker. The ghost body that was originally full of oppressive power has become very weak, as if it can be blown away by a gust of wind, and it no longer has the fierceness before.
But miraculously, his extremely ugly face became slightly softer.
It was so ugly that it would make people vomit just looking at it. Now I still want to vomit, but I can finally hold it back.
The Buddha refining the ghost flag flicked, and the evil ghosts quickly jumped into the flag flag.
Seeing him looking like he was being pardoned, Xu Wen was both annoyed and amused.
This fight with the White Ghost allowed Xu Wen to gain a deeper understanding of the Buddha's Ghost Flag and the true purpose of the flag.
As the name suggests, the main function of this thing is to refine other ghosts.
Whether it is the evil ghosts in it or the golden light formation of the flags, they are all refined using extremely special methods and have extremely strong restraint against ghosts.
But if used against a living person, the Buddha's Refined Ghost Flag is not even as good as an ordinary magic weapon, just like the evil ghost fighting Qiu Yunsheng. It is obvious that the opponent's rank is far superior, but it was beaten to almost annihilation.
Fortunately, Xu Wen didn't like fighting with others, so he didn't rely on this third-level magic weapon to force himself. If he used it carelessly like the previous owner, this Buddha's Ghost Refining Banner would be destroyed in one day.
As for whether the evil ghost will still be so cowardly and stupid after complete recovery, it is not yet clear.
