The theory of ghosts and monsters is not much of a terrifying thing for Xuanshi, after all, the so-called cultivation path is actually the real killing path, and it is impossible for Xuanshi who have really cultivated to a certain level without blood on their hands, and if they kill more people, they will naturally not be particularly afraid of ghosts, ghosts and the like.

When Yu Changan said the words "It seems to be a ghost", the demon warriors did not panic at all, but looked for it more seriously.

After searching for a long time, the sledgehammer didn't find any special signs, so he couldn't help but ask curiously: "Boss, what are the ghosts?" Is there a real ghost or something weird?"

"There are ghosts. Yu Changan said to himself, and when he said the first sentence, his eyes were always locked in one direction, and the sledgehammer followed his gaze but still didn't find anything special.

Just when the sledgehammer thought that Yu Changan was too nervous, Yu Changan suddenly rode out violently. The speed of Ao Lie's charge was extremely fast, and he rushed out dozens of feet away in the blink of an eye, and the sledgehammer looked at Yu Chang'an's crotch mount suspiciously and muttered: "A donkey can run so fast?"

Although Yu Changan had been hiding in Tibet with the demon warriors in the previous time, they did not move forward at full speed because they did not know the true movements of the enemy, and now this charge really showed Ao Lie's amazing speed. Yu Changan was also shocked by Ao Lie's swiftness, and this charge almost caught up with the speed at which he used his full strength to perform a surprise attack, but the surprise attack could not reach the extent of rushing out dozens of zhang away in an instant.

Before he could sigh at Ao Lie's speed, he already felt that the strange aura had become extremely strong, and it was obvious that he was very close to the target hiding in the shadows.

Subconsciously, Yu Changan used the power of the Xuanyin bone, and his Xuanyin bone had the power of pure Xuanyin, which was also the most important support for Wu Zetian to hide in. And this was the first time that Yu Changan took the initiative to guide the Xuanyin bone to release the power of Xuanyin, and when his palm poked forward, he saw a burst of thick ink-like things instantly spread in front of him.

The moment the power of Xuanyin dispersed, Yu Changan saw a strange existence standing in front of him at a glance.

It was a dead corpse that looked dead and couldn't die anymore, the corpse was wearing nothing, the corpse gas was slowly emanating from the body like mist, and the corpse's face had holes of various sizes, and some maggot-like things were burrowing through those holes.

Since he became an envoy to the underworld, Yu Changan has seen a lot of ghosts, but whether it is Wu Zetian or Guan Yu, although they are ghosts, they have bodies that are no different from human beings, not only are they not a little terrifying, but they even have different momentum.

But the dried corpse in front of him can only be described as terrifying and weird, and this dry corpse looks lifeless, and after being discovered by Yu Changan, there is no sign of wanting to escape or make a move, he just floats there in a daze, as if he doesn't know that he has exposed his whereabouts.

"Your Majesty, do you know what the hell this is?" Looking at the "dry corpse" in front of him, Yu Changan asked secretly.

"Can't you feel this, this is a ghost. Wu Zetian replied.

"Ah, isn't it true that the yin soul can't move around the yang world at will?" Yu Changan asked puzzledly, this was actually what he was really puzzled about, the reason why he was able to find this ghost thing hiding here before was because he felt a strange aura, and the so-called strange aura was actually a breath very similar to Wu Zetian's body, and it was because of this that he couldn't understand why there was such a thing here.

"This can't be the lost customer sent by Boss Bai, right?" Yu Changan subconsciously asked again.

"No, not all Yin Spirits are like us, this should be something made by some cultivators who have a certain degree of study of the power of Xuanyin. Wu Zetian gave his own guess.

"Ghost cultivator?" Yu Chang'an's mind suddenly popped up these two words, he knew that in addition to the orthodox martial artists and legal practitioners in the cultivation world, there were actually some different existences, such as ghost cultivators, although they also cultivated Xuan power, they also studied other forces such as Xuan Yin power.

Yu Changan had heard that ghost cultivators knew how to exorcise ghosts, but he didn't expect that a rumor he heard in the past would actually see the real thing today.

"What should I do with this thing?Can I kill it?" Yu Changan asked weakly, after all, this thing in front of him and Wu Zetian belonged to the same "species", Yu Changan was afraid that he would be strongly reacted by Wu Zetian after he had the idea of killing this ghost thing.

As a result, he didn't expect Wu Zetian to reply indifferently: "If you can kill it, kill it, what are you applying for with me about this little thing." ”

"Good. Yu Changan nodded, and then prepared to start. Although he didn't know how to deal with this thing yet, thinking that the other party had been hit by the power of Xuanyin in his Xuanyin bones, it was estimated that he could kill it with a normal shot.

At this moment, Hua Tuo suddenly spoke: "Chang'an, I'll teach you a hand in soul alchemy." ”

"What?" Yu Changan stopped in time and immediately asked, "Doctor Hua is now convenient for imparting special abilities to me?"

"The power of Xuanyin here is extremely strong, and it's no problem to do this little thing here. Hua Tuo explained: "Before, because of the poor state, and secondly, I didn't think about what kind of ability is better to pass on to you, but now it seems that this soul alchemy technique is very suitable for you." ”

Out of time urgency, Hua Tuo explained at a very fast speed what soul alchemy was. The effect of this special ability is that Yu Changan can refine the yin soul he found, and then transform it into soul power for his own use.

"For low-level Xuan Shi, soul power is actually not a very important thing, after all, your current combat methods are only to urge Xuan power, but after your strength increases, having sufficient soul power will be of great help to your combat ability. Wu Zetian once again turned into Yu Changan's teacher and gave him a very clear explanation.

"Okay, no matter what use it is in the future, it just works now. Yu Changan nodded again and again, and then got the soul alchemy from Hua Tuo with ease.

The moment he mastered the soul alchemy, Yu Changan couldn't wait to cast it, and after a black light flashed, the yin soul that had been looking "stupid" after it appeared was easily refined by him, and then he found that there was indeed a special soul power in the soul of life, and this soul power was also extraordinarily strong, although it could not be used directly, but he could feel that over time, this part of the soul power should be able to warm his soul soul.

"Thank you, Doctor Hua. Yu Changan solemnly thanked him, the alchemy technique that Hua Tuo taught him could indeed play a big role for him now. The main reason why he was in such a hurry to kill this yin spirit was that he suspected that this yin ghost definitely did not happen to appear here, but was very likely to be related to Yanagi.

Before entering the battlefield, Yu Changan had a guess in this regard, Liu Sheng dared to fight a decisive battle with Gu Yu whose strength was much higher than his own at that time, and he must have something to rely on, and the choice of Guzuka Peak for the battlefield is the most powerful proof, and in this place where the power of Xuan Yin is strong, it is not surprising that the means he relies on are related to Yin Soul.

Although Yu Changan didn't find anything special after killing the Yin Spirit, he still immediately ordered everyone to follow him and continue to escape, he always felt that when this Yin Spirit appeared, he had already become the prey targeted by hunters, and now it was still far away, and he didn't want to be chased by Liu Sheng.

When Yu Changan was refining the corpse-like yin soul here, Sledgehammer and their demon warriors were standing beside him, at that time they were all confused and watched Yu Changan standing in place as if acting, sometimes smirking, sometimes with a serious expression, at that time Sledgehammer thought that Yu Changan was evil, but before he could ask, Yu Changan had already recovered and began to flee with them. It wasn't until he escaped far away that Sledgehammer finally couldn't help but ask, "Boss, what were you doing there just now?"

"Cultivation. As soon as Yu Changan heard Sledgehammer's words, he knew that his strange behavior just now had fallen into their eyes, so he simply pretended to be a profound reply.

"Is it an epiphany?" Sledgehammer's eyes widened, although the demon seed has a special identity, but after all, he can be regarded as a cultivator, Sledgehammer has always heard that some people in the cultivation world will occasionally have an epiphany, and his strength will increase by leaps and bounds, thinking of Yu Changan's strange behavior just now, he subconsciously thought of the epiphany.

"Epiphany. Yu Changan replied angrily, and then without saying a word, he led everyone to continue to circle between the hills.

----

"Uh......" As he walked quickly, Master Yihe suddenly stood up straight, his face pale and spit out a mouthful of blood.

Seeing this, Liu Sheng hurriedly motioned for everyone to stop, and asked with concern, "Master, what's wrong?"

"My soul has been destroyed. Master Yihe's expression was very ugly, and his eyes were a little incredulous.

"What?" Liu Sheng was also surprised, and subconsciously asked, "Master, didn't you say that ordinary people can't see corpse souls?"

"Ordinary people naturally can't see corpse souls, but if there are ghost cultivators in the other party's team, they can see it. Master Yihe explained with a wry smile, but his current expression was full of incomprehension, and after a while, he said, "Anyway, be careful." ”

"The other party is strong?" asked Yanagi with a frown.

"It should be very strong, although I have only been refining the corpse soul I released for a year, but after all, it has been completed, even if the other party is also a ghost cultivator, it should be difficult to kill the corpse soul instantly. Master Yihe shook his head and said, and then kept repeating the advice of "be careful".

Liu Sheng was upset when he heard it, and it was not easy to attack directly, so he had to wave his hand and ask, "Then what should I do next?"
