The reason why Lin Feng wanted to take this old man away was mainly because he was very curious about that heaven-level spell 'Blood Melting Demon Claw', the power of that blood-colored demon claw did not reach the standard of heaven-level spells, but it was very weird. Attacking a person can not only cut off all life of a person, but also increase one's own power.

This kind of forcible seizure spell was rare, at least Lin Feng had never heard of it before, let alone seen it.

This area is vast, with lofty mountains and mountains, and canyons and evil peaks can be seen everywhere. Lin Feng and the three of them landed in a very beautiful canyon, where the environment is very beautiful, with flowers and streams.

Lin Feng threw it casually, and the old man rolled on the ground like a gourd for a long distance, he was still very conscious, and the battle just now fell in his eyes. Three young people who seem to be harmless to humans and animals, their strength is actually more terrifying than the other.

"This fellow Daoist, it doesn't matter if you hurt the old man and the others, but if you hurt my young master, Dazun will not let you go. ”

"Who is the Blood Demon Venerable?"

The old man was stunned for a moment, and suddenly laughed wildly, "Even the Blood Demon Venerable doesn't know that you still want to be arrogant in Sin City." ”

With a 'snap', Lin Feng casually slapped him and said with some contempt, "Why do I want to know who the Blood Demon Venerable is?" The reason why I haven't killed you is because you still have a role, since you are so ignorant of lifting, then let you see my methods." ”

As soon as the dark soul in the Purple Mansion space moved, a hundred and ten black runes appeared in the condensing sky, each rune was burning with flames, Lin Feng couldn't help but evolve various different handprints with both hands, and finally shouted in a low voice, "Condensation." ”

One hundred and ten runes immediately shook, and began to merge and condense continuously, and finally a black golden 'lock' word appeared. This 'Forbidden Soul Seal', which was able to be used in the mortal stage, also produced a transformation after breaking through the Dao Transformation Realm, and its power was increased by twenty times.

Lin Feng also learned from the 'Pan' that this kind of domineering technique seemed to be born out of some lost 'pseudo-immortal technique', and its power would continue to increase as the caster's cultivation improved.

The word 'lock' floating in the air exudes a bewitching light, as if people will be suppressed by the word lock at a glance.

"Locks. Lin Feng pointed at the old man's eyebrows, and the word 'lock' turned into a black light and drilled into the old man's purple mansion.

"Ahh The old man immediately rolled on the ground with his head in his hands, and his body curled up into a lobster. Ziyi had seen Lin Feng's methods many years ago, so he wasn't surprised, but Fang Rou beside him couldn't help but take a few steps back when he saw a big change in his eyes.

Half an hour later, the old man didn't move, slowly got up from the ground, walked to Lin Feng's side and bowed respectfully, "Old slave Cheng Feng pays a visit to his master." ”

"Huh?" When Cheng Feng knelt down and bowed, Lin Feng suddenly felt that a trace of very weak power in the void space had infiltrated into his Purple Mansion space, and then merged into that dark soul thought. As soon as this trace of power touched the soul fire, it was like an ice cube instantly vaporizing, turning into a thin puff of smoke, transforming into a trace of pure dark power, which was replenished into the dark soul thoughts.

"What kind of power is this?" Lin Feng sensed the change in his dark soul thoughts, and couldn't help but be surprised, this external force was too sudden, and it was endless. Although it is very weak, it can change significantly over time.

"The Origin of Darkness! How is it possible, you actually inspired the Origin of Darkness, how did you do it, this is definitely an illusion. He shouted in his purple mansion, and his condensed human form also sensed the change in the dark soul's thoughts.

"In order to bring out the source of any kind of power, it is necessary to use the power of faith. And the people who have believers are generally people who have cultivated the Divine Spirit Dao Infant, and they are a rule-realm powerhouse with a lifespan of 10,000 years. Lin Feng, although the dark origin power you have inspired is weak, it is indeed the true origin power, if you can cultivate the origin power to the peak before cultivating the power of the rule realm, then in the future, the certainty of changing your life against the sky and surviving the sixfold earth tribulation will increase by eight layers. ”

Only the power of faith can stimulate the power of the origin, although Lin Feng couldn't understand it, he also knew how useful this source power was for his own cultivation.

"Could it be that the mutation of my dark soul mind has something to do with this Cheng Feng in front of me?" Lin Feng glanced at Cheng Feng with his eyes, and there was a burst of suspicion in his heart.

"Cheng Feng?"

"The old slave is here. Cheng Feng bowed again, and his entire body almost fell to the ground.

Lin Feng suddenly sensed that there seemed to be more of that dark power, "Sure enough, I didn't expect that the Forbidden Soul Lock Seal would have such an ability." ”

When Lin Feng confirmed that he had reached this conclusion, the 'disk' in the Purple Mansion space also showed such a look, and he muttered in his mouth, "This forbidden soul lock spell is really related to that pseudo-immortal 'ignition'. If this Lin Feng could reactivate the origin of the power of light, then he would be able to break the routine and not have to wait until he had advanced to the Divine Power Realm to comprehend and cultivate his Divine Power. The sooner you comprehend the magic, the higher your future achievements. ”

"Record the cultivation method of the heaven-level spell 'Blood Melting Demon Claw', and then find an excuse to go back and be your subordinate." Help me keep an eye on all kinds of information in Sin City for the next period of time, and come to me immediately if there is anything out of the ordinary. ”

"Yes, master. Cheng Feng used the memory crystal to write down the cultivation method of the spell, and then respectfully kowtowed three times and exited the canyon.

"Senior brother, how can you let this person go? If that Blood Demon Venerable is a very powerful power, then what is the use of him going back, in case he is searched for souls, I'm afraid we won't have a place to stay. Ziyi took two steps forward and said with some puzzlement.

"What do you know? If that Blood Demon Venerable was really a Rule Realm powerhouse, then he definitely wouldn't have such a great reputation. Being able to make the vast majority of people change their voices in the Sin City can only mean that this person is not good or evil, and according to my estimate, he is also the most fatal cultivator. Fang Rou glanced at Ziyi and immediately retorted.

"You... Ziyi's face turned red, and he was about to have a seizure, but Lin Feng cut off the conversation.

"Alright, you all don't fight. Miss Fang Rou was right, that Demon Blood Venerable was a Demon Dao cultivator who had been famous for more than six hundred years, and this person had been cultivating in the Sin City for more than six hundred years, and his cultivation had already reached the peak of the Tribulation Realm. ”

"Hmph, well, I guessed right. Fang Rou raised her chin proudly. The corners of Ziyi's mouth twitched, ignoring him.

Lin Feng used his soul power to scan the memory crystal and then passed it to Ziyi. After the purple-clothed soul power was swept away, his face was extremely ugly.

"Hey, this heaven-level spell is really not an ordinary cultivation method, and it actually has such power after Dacheng. I'm afraid that the six heaven-level heavenly snake spells that Mo Xiaoxuan has cultivated may not be the opponents of the secondary spells. That Blood Demon Venerable was really terrifying, and he actually created what a terrifying heaven-level divine power. ”

Zi Yi handed the memory crystal to Fang Rou and continued, "That Blood Demon Great Venerable spent five hundred years to create a heaven-level divine power 'Blood Prison' that could easily trap and kill two or three powerhouses of the same realm. The heaven-level spell that Cheng Feng cultivated was just a trace of the surface that came out of this 'Blood Prison' supernatural power. ”

"Senior brother, this Blood Demon Venerable seems to be very difficult to mess with, what should we do? That evil domain hasn't come yet, don't be approached by your old thing to settle accounts before this. Hey, I regret following you all the way. Fang Rou's tone had a hint of anxiety.

"It doesn't matter, if the person who was abolished by us is really a descendant of the Blood Demon Great Venerable, his strength will definitely not be so low. There should be some magic weapons on his body, so I guess that the elder of that person should have something to do with the Great Venerable of the Blood Demon. I let Cheng Feng go back to test it, if Cheng Feng is dead, I can also sense it, we can leave early. Lin Feng waved his hand and looked around, "Before the Evil Domain descends, I have to comprehend the power of light and darkness first. ”

The three of them found a hidden cave, and after laying out a sword formation outside, they began to retreat. Having activated the power of the Dark Origin just now, Lin Feng sensed that the dark sigil in the Dark Soul seemed to be loosening, and a message came out, and he had to digest it well.
