This blood-robed old man in the late Yuan Infant stage faced Ling Feng's superb primordial spirit, and was suppressed without any resistance.

Immediately, Ling Feng searched for his soul, then refined his divine soul, took away his body, and cast an impermanent change, perfectly replacing this Blood Demon Sect elder named Blood Spring.

Then, Ling Feng's memories of the Blood Fountain went to the Blood Demon Cave where the Blood Demon Ancestor was retreating.

In the back mountain, in the Blood Demon Cave, in a blood pool filled with bright red blood, a middle-aged man in blood clothes sat on a high platform in the center of the blood pool, and his luck was exhaled, and the rich blood evil vitality continued to submerge from the blood pool into his body, and was quickly refined.

The middle-aged man in the bloody clothes was the Blood Demon Ancestor, and the blood in this blood pool was not ordinary, it was either the essence blood of a high-level cultivator above the Jindan level, or the essence blood of the demon beasts above the Jindan level. Moreover, this pool of essence blood also added a lot of cherished elixirs, and locked the aura in the blood pool with a formation.

Immediately, Ling Feng's pretended Blood Spring Daoist came to the outside of the Blood Demon Cave, and said aloud with a respectful expression: "Ancestor, the Blood Spring has something important to see!"

The Blood Demon Ancestor's palm moved, but it didn't seem to wake up, and he still sat cross-legged and cultivated.

In fact, the forbidden method of the Blood Demon Cave couldn't stop him at all, but in order to quietly destroy the Blood Demon Ancestor, Ling Feng still waited at the door with a respectful face, and did not act rashly.

Ten minutes later, a majestic voice came from the Blood Demon Cave: "Come in!"

Immediately, Ling Feng stepped forward slowly, only to find that the forbidden method at the entrance of the cave had been lifted, so he walked straight into the blood pool in the Blood Demon Cave.

At this time, the Blood Demon Ancestor stared at Ling Feng and said coldly, "Blood Spring, let's say, what the hell is going on?"

Ling Feng said respectfully, "The thing is...... You're going to die!"

By the time the Blood Demon Ancestor sensed that something was wrong, Ling Feng's Xuanyin Yuan Shen had suddenly turned into a black light and rushed into his eyebrows, entering the Sea of Knowledge.

The Blood Demon Ancestor's Blood Demon Yuan Divine Law was a vast and boundless sea of blood, sensing Ling Feng's divine soul attack, and immediately a stream of blood qi rushed to the sky, turning into a dozen ten-zhang tall Shura Blood Demons holding blood-colored swords and attacking Ling Feng.

However, Ling Feng's Xuanyin Yuan God suddenly turned into a vast and boundless black Styx, sweeping everything, and more than a dozen Divine Soul cultivators who were not inferior to the Yuan Infant Great Cultivator level Shura Blood Demon were instantly devoured, and the mighty Styx River was castrated, swallowing the entire sea of blood into it!

In fact, Ling Feng still underestimated the realm of the Transformation Spirit, with the accumulation of the Yuan Infant Stage, the cultivation of the Transformation Stage cultivator was far deeper than that of ordinary Martial Honor, and the cultivation of the Blood Demon Ancestor was also extremely strong, not inferior to Bai Haoyang. However, Ling Feng's Xuanyin Yuan Divine Cultivation was close to the level of the Bull Demon King, equivalent to three or four times that of Bai Haoyang's Divine Soul Cultivation, which was much higher than that of the Blood Demon Ancestor, and was suppressed by the power of the Xuanyin Dao, which suppressed the Blood Demon Ancestor's Divine Soul almost instantly.

An hour later, Ling Feng had completely refined the Blood Demon Ancestor's divine soul, and through the soul searching technique, he had obtained most of the Blood Demon Ancestor's memories. One of the most valuable harvests is the Blood Demon Sect's Zhen Sect Exercise "Blood God True Scripture", and the grade of this exercise is extremely high, it is a seventh-order mid-grade exercise, which originates from the Blood God Sect that was destroyed by the main world thousands of years ago. The Blood Demon Ancestor is actually the descendant of the Blood God Sect!

It was not easy to obtain a seventh-order exercise, but unfortunately it was a Blood Demon Dao exercise, which could only be used as a reference. But Ling Feng was not disappointed, because compared to this, the large amount of chivalrous value and essence value he obtained was the real income. Just by killing the Blood Spring Dao people, he gained more than 100,000 chivalrous points, and the Blood Demon Ancestor, a thousand-year-old monster, dropped more than 1 million chivalrous points.

Moreover, after Ling Feng killed the Blood Demon Ancestor, he also triggered a mission, exterminating the Demon Dao of the Mountain and River Realm! The task requirement is to destroy the sect masters of the three major demon sects and most of the demon path disciples, the task reward is 3 million chivalrous values, and the time limit is seven days.

This coincided with Ling Feng's thoughts, his original purpose was to use the power of the Demon Dao to search for the missing students. If the task is completed, he will personally destroy this group of demon Dao disciples and earn chivalrous points.

Immediately, he refined the Blood God Yuan Shen of the Blood Demon Ancestor according to the exercises of the Blood God Sutra to form a blood god clone, and completely refined the body of the Blood Demon Ancestor into a blood god son in the energy state, so that there was no weakness. As for the corpses and Yuan Ying of the Blood Spring Dao people, they naturally used the blood god clones to suck their power dry.

Then, Ling Feng began to refine the Blood Demon Yuan God with the help of the Yin True Fire condensed by the power of the Xuanyin Great Dao, and purify his own cultivation. Although this Blood Demon has a profound cultivation, many of them are from taking the cultivation of others, and they are not pure enough, and they need to be purified to fully recover their cultivation.

After the cultivation was completely purified, Ling Feng absorbed the blood evil vitality of the entire blood pool, restored the cultivation to perfection, and then refined the Blood Demon Ancestor's natal magic weapon, the Blood Flame Divine Sword. At this time, his cultivation did not seem to have improved, but his combat power was much stronger than that of the Blood Demon Ancestor, and his Xuanyin Yuan God was hidden in the Blood God clone, so it was not difficult to deal with the two Soul Refining Demon Sects and the two Transformation God Ancestors of the Xuanyin Demon Sect.

On the second day, Ling Feng summoned all the high-level leaders of the Blood Demon Sect above the Jindan level, planted a new blood seed for all the high-level leaders, replaced the Blood Demon Ancestor's Blood Demon Seed, and showed the photo of the missing student, ordering everyone to search his whereabouts. In fact, he can also quickly kill all these people and obtain chivalrous points, but in the first place, it is difficult for him to find the traces of the missing students alone.

Immediately, he left the Blood God clone behind and sat in the Blood Demon Sect, while the Xuanyin Yuan God quietly went to the Soul Refining Demon Sect. It took him an hour to rush to the Soul Refining Demon Sect, and by snatching and regaining it, he almost didn't waste much strength, and killed the Soul Refining Ancestor in the late stage of the Transformation Spirit, refining his Yuan Shen into a clone, and replacing it.

Then, Ling Feng took the soul refining clone to sit in the Soul Refining Demon Sect, and planted all the high-level monks above the golden pill in the sect with soul seeds, leaving the portrait of the missing student, and ordered them to look around. And his Xuanyin Yuan God quietly went to the Xuanyin Demon Sect.

An hour later, Ling Feng rushed to the Xuanming Demon Sect, and through the seizure, he came into contact with the Xuanming Ancestor in the late stage of the Transformation of the Gods. Then he easily refined the primordial spirit of the Xuanming Ancestor, refined it into a body, and then controlled all the high-level and ordered others to search for the whereabouts of the students. The three high-grade sects of the Demon Dao, plus their affiliated sects, are extremely powerful, as long as that person is not dead, they can always find clues.

At the same time, Qiu Yue'e had been missing for a long time, and Wei Changhe, the sect leader of the Three Rivers Sect, finally sent someone to look for it, but only found the two dresses left behind on the cliff, and the wisps of pure demonic energy on them undoubtedly showed that they were the hands of the Demon Dao Sect. What will happen to a very beautiful woman who is taken away by the devil is self-evident!

Wei Changhe felt that there was an extra green grassland on his head, and he was extremely angry in his heart!
