A few days passed, and as the people of the Soul Gate and the other three major forces investigated at night, they were shocked to find that there would be people sucking human blood everywhere in Kyoto, that is, not just one person, but a dozen!

Tonight, Xiao Chen and a few people went to investigate in person, wanting to see who it was!

"It's been ugly, I've been waiting for two hours, why hasn't it appeared yet?" Ghost Tu asked with a frown, waiting a little anxiously. [Ran^Text^Library] []. [774] [buy]. [com]

Mu Yunshan frowned and said, "Wait a little longer, it will definitely appear." ”

"The 'Gate' Lord, the Ghost Slayer Brother, after our observation, they generally appear when they are from the beginning of the day to the end of the day, and although they are crazy, they seem to be very conscious. Xiaotian said in a low voice.

After more than ten minutes passed, the quiet night, at this moment, gave people a cold feeling.

"Someone's coming!" Xiao Chen frowned, sensing someone appearing and quickly skimming across the void.

Seeing the black shadow flying by, Xiao Tian hurriedly said: "The 'Gate' Lord, it's him!"

Although the speed of the black shadow is fast, his eyes are blood-red, and his face is pale and crazy, just like when the ghost slaughter was controlled by the demons, it is very terrifying, Xiao Tian recognized it at a glance.

"Over there!, in the direction of Heavenly Immortal City!" Ghost Tu whispered, and saw a figure flying by quickly.

"Chase!" Xiao Chen said in a low voice, and several people quickly flew in pursuit.

"Woohoo!"

The sound of breaking the sky sounded, and Xiao Chen and the others hurriedly chased after the black shadow just now, and disappeared in a flash.

The black shadow seemed to sense that someone was pursuing, and the black shadow suddenly increased its speed, and after entering the Heavenly Immortal City, it hid.

Xiao Chen and the others pursued after them, and they had lost the trace of the black shadow.

"This guy is so fast! gone!" Ghost Tu frowned, and quickly glanced around, but he didn't notice a single figure.

"In the realm of the middle stage of the tribulation, everyone must be careful!" Xiao Chen frowned and said, in this case, the 'Yin' Yang Xuan Vein couldn't help, after all, the black shadow had reined in his breath and stopped moving, and the 'Yin' Yang Xuan Vein couldn't detect it.

"Xiao Chen, it smells of blood! over there!" said the Ancient White Tiger.

"Follow me!" Xiao Chen said in a low voice, flying in the direction pointed by the ancient white tiger.

"Xiao Chen!" Xiao Chen and the others had just left, and below them, a crazy-looking person whispered, his voice low and cold, very terrifying.

Xiao Chen and the others didn't notice it, so they had already flown forward.

In the direction that the ancient white tiger said, in the corner of a building below, a monk was biting the neck of a monk, covering the man's mouth to prevent him from making a sound, and the monk who was being sucked by blood widened his eyes, full of horror and despair.

"Woohoo!"

At this time, Xiao Chen and a few people appeared, but it was too late, the blood-sucking monk, the Yuan Shen had been destroyed and died.

Xiao Chen frowned and asked, "Who are you?"

The blood-sucking black shadow slowly raised his head, his blood-red eyes swept towards Xiao Chen and the others, his face was full of blood, and his two long teeth were 'exposed' out of his mouth, looking extremely terrifying.

"Yan Yifei?" Xiao Chen was suddenly startled and recognized the person who sucked human blood.

"It turned out to be Yan Yifei! How is this possible?" Ghost Tu and the others were shocked, they never thought that it would be Yan Yifei, the young master of the Yan family, who sucked people's blood!

"Xiao Chen, save me, I, I can't control myself! I'm so miserable!" Yan Yifei said with a crazy and painful look, and after speaking, he quickly flew away into the distance.

"Hurry up! We must 'figure out' what is going on!" Xiao Chen hurriedly said, quickly chasing after Yan Yifei.

"No! How could Yan Yifei have been promoted to the early stage of the tribulation in such a short period of time? And I haven't heard of someone crossing the tribulation recently, strange, is it related to sucking human blood? Wait, the early stage of the tribulation? The person we were chasing just now was in the middle of the tribulation, could it? The blood demon 'girl' secretly said in her heart, thinking of the back, she couldn't help but change her face greatly.

The Blood Demon 'Girl' glanced back at Tianxian City, and didn't say much, now that Yan Yifei was caught, it was more important to 'figure out' the matter.

"Xiao Chen! I'll go find you. After Xiao Chen and the others left, a crazy black shadow appeared, and his voice was low and cold.

"Ghost Shadow Divine Decision!' Yin' Yang Xuan Vein!" Xiao Chen let out a low snort, speeding up his speed, and at the same time casting the 'Yin' Yang Xuan Vein to check.

Yan Yifei's position Xiao Chen immediately locked, Xiao Chen's speed was extremely fast, and when he reached a mountain range near Tianxian City, he caught up with Yan Yifei.

"Shenluo Heavenly Xuan Array!Four 'Gates' Enchantment!" Xiao Chen quickly urged Zhenyuan, sealed with both hands, and then let out a loud shout and waved his hand.

A huge formation enveloped Yan Yifei, and at the same time, it was also blocked by a powerful enchantment on all sides, making Yan Yifei unable to move.

"Let go of me!" Yan Yifei shouted angrily, letting out a roar like a demon beast.

Xiao Chen entered the formation, observed Yan Yifei for a moment, and then asked, "Yan Yifei, what's going on, how did you become like this?"

"Roar!Xiao Chen, let me go!I can't stand it! I want to suck blood!I want to suck blood!," Yan Yifei roared in an extremely crazy manner, his mouth flowing with a mixture of saliva and blood, extremely disgusting.

"What's going on? Yan Yifei's cultivation is now improving rapidly, does this have anything to do with sucking human blood?" Xiao Chen said in his heart, very shocked.

Mu Yunshan and the others rushed over, and when they saw Yan Yifei's crazy appearance, several people were very scared.

"He.Is he really Yan Yifei?, how did his cultivation become so terrifying?" said Netherworld, his voice trembling.

"Xiao Chen, there is another person in Tianxian City, Yan Yifei is only in the early stage of the tribulation, and the person we chased before is in the middle of the tribulation!"

Xiao Chen nodded and said, "I know, but the most important thing now is to 'figure out' what is going on, otherwise there will be more deaths!"

"What? Isn't this going to scare the brothers to death?" exclaimed in fear.

"Don't worry, Yan Yifei is trapped by me and can't get out!" Xiao Chen said, and then urged Zhenyuan, using powerful power to trap Yan Yifei, and quickly cast the teleportation array to leave.

"Whew!"

In less than half an hour, Xiao Chen and the others returned to the Soul Gate, although it was already ugly, but the people in the Soul Gate were still waiting, and when they saw Yan Yifei who was crazy, they were all frightened, and no one dared to approach.

"Xiao Chen, let go of me! let go of me!" Yan Yifei roared angrily, and the voice like a demon beast once again startled everyone in the soul 'gate'.

"Brother Xiao Chen, why did you get him back?" Xiao Ling said with a frightened face, and his pretty face turned a little pale.

"Is he a human or a ghost?" Mu Qing said in fear, not daring to look at it at all.

"Don't be afraid, he is Yan Yifei, and he has been trapped by me. Xiao Chen hurriedly said, signaling that everyone did not need to be afraid.

"What?Yan Yifei?" everyone was shocked when they heard this.

"Xiao Chen, his cultivation has improved so fast!" Ghost Tu said in horror, a little worried that Yan Yifei would break through Xiao Chen's enchantment control.

"Yan Yifei, what happened? If you don't say it, we can't help you at all!" Xiao Chen hurriedly asked, secretly anxious in his heart.

"Yan Yifei, you are talking!" Mu Yunshan said anxiously.

"Snort!"

Yan Yifei trembled violently, and his violent anger surged out, and his cultivation had actually advanced to the middle stage of the Tribulation at this moment! The enchantment that trapped Yan Yifei began to make a sneering and tearing sound.

"Not good!" Xiao Chen's face suddenly changed, quickly urging the true yuan and strengthening the enchantment!

"Roar!"

Yan Yifei became more and more crazy, and after roaring, Yan Yifei roared angrily: "I want to suck blood! I want to suck blood!"

"Don't worry, when he arrives, he'll be back to his senses. At this time, Jiaolong Ao Tian in mid-air said.

Hearing this, everyone was stunned, and then they all looked at Ao Tian, Xiao Chen asked in surprise: "Ao Tian, do you know what happened to Yan Yifei?"

"More than a thousand years ago, when there was still a Poison Sect in the cultivation realm, a Poison Sect master developed a kind of 'medicine' powder, called Soul Hypnotic San, which can catalyze people's life origin to transform power, that is, to improve cultivation at the cost of consuming the source of life. Ao Tianshu said.

"Soul Booster, isn't the Poison Sect already destroyed, and Senior Situ is also dead, who else in this cultivation realm can refine Soul Booster?" Mu Yunshan asked suspiciously, looking very shocked.

"The people who developed the Poison Sect back then betrayed the Poison Sect, and they broke away from the Poison Sect as early as that year, and later disappeared. Ao Lei said.

"Isn't this man dead?" asked Horror, wouldn't it be terrible if he was really alive?

"Since the Soul Hypnotic Scatter has appeared, it means that this person is still alive!" Xiao Chen frowned.

"Xiao Chen, save me!" At this time, Yan Yifei begged, his voice returned to normal, and his face returned to normal, but Yan Yifei in this matter already looked very old, a young man of twenty years old, and now he has become almost forty years old, with white hair.

"Xiao Chen, Yan Yifei has come to his senses!" the Blood Demon 'Girl' said hurriedly.

Xiao Chen waved his hand, withdrew the enchantment, and hurriedly asked, "Yan Yifei, what the hell is going on? Who gave you the Soul Booster?"

"It's the wind that breaks the sky! That beast held me hostage, and 'forced' me to eat a pill 'medicine', saying that it could help me improve my cultivation, I was not his opponent, he 'forced' me to eat, and then I became like this, as soon as I came to night, I would go crazy, very painful, become very bloodthirsty, after sucking blood, my cultivation would improve rapidly in vain, Xiao Chen, you save me, I beg you! I don't want to 'become' the appearance of a person who is not a ghost or a ghost. Yan Yifei hurriedly knelt down and pleaded, his face full of fear.

"What?

"How could it be him? This can't be?" said Destroyer in horror.

"Get up, get up! I'll find a way to save you, don't worry. Xiao Chen hurriedly said, helped Yan Yifei up, and couldn't believe it when he saw Yan Yifei's old appearance.
