Nie Fei was slightly taken aback, Nie Fei's aura was comparable to that of the early stage of general foundation building, his aura was very condensed, no less than dozens of times higher than that of monks of the same level. But even so, his aura was still blocked by Liao Yan, which was a little unexpected by Nie Fei.

Liao Yan's eyes revealed a complete madness, and the first aura was blocked by Nie Fei, which could only make the hatred in his heart deeper. Liao Yan felt that his body seemed to be about to explode, and he could only release it if he destroyed it. "Ruined miè...... Destroy miè ......" Liao Yan shot again, blasting out the aura with all his might, but was blocked by Nie Fei again.

Liao Yan followed two or three, and blasted out fourteen aura attacks with all his might, but each time, he was blocked by Nie Fei. The aura of the two collided, and fourteen loud bangs erupted.

A cold light flashed in Nie Fei's eyes, the battle between the two was too loud, I am afraid that it had already alarmed the others in Yanfenggang at this time. Nie Fei didn't want to delay any longer, and when he shot again, he had already mentioned seventy percent of his aura. Seventy percent of the aura is enough, Tong guò fought with Liao Yan more than a dozen times before, Nie Fei noticed that Liao Yan's aura strength was just like that, and his seventy percent aura could completely kill the other party.

Nie Fei's aura was already in front of Liao Yan in the blink of an eye, and Liao Yan hurriedly raised his aura to resist. However, a sharp pain came from the sea of qi, and even if Liao Yan broke his arm, the aura could not be stimulated at all. It turned out that in the first dozen attacks, each time, Liao Yan tried his best, and after a dozen times, the aura in Liao Yan's sea of qi had been exhausted. At this time, he wanted to stimulate the slightest bit of aura, but he couldn't do it.

In an instant, Nie Fei's aura swept through Liao Yan's body, and Liao Yan's face, with that monstrous hatred, turned into an ice sculpture.

With a slight wave of Nie Fei's hand, Liao Yan's ice sculpture exploded violently, turning into fine ice crystals and floating in the air.

......

Nie Fei's move this time was entirely to test a new drug he had prepared. That kind of medicine is the product of the reaction of three herbs, Divine Soul Grass, General Fruit, and Clear Whisker Root, which are mixed together. Divine Soul Grass can make people delirious, General Fruit can stimulate the potential of the human body, and clear the root of the beard has the effect of calming and calming the nerves. When three herbs are put together, they can react.

Generally speaking, the products obtained after the reaction basically do not have the effect of the original material. Nie Fei didn't know what the effect of this obtained product was. Therefore, he did a test on the cold corpse, and found that the cold corpse became irritable after taking the medicine, and at the same time, the cold corpse's originally pale eyes also swelled with bloodshots, giving people a sense of bloodthirstiness. Of course, because the cold corpse has no divine sense, he can't speak, and he can't say how he feels, but Nie Feitong observed and found that the effect of the drug is related to people's sanity.

Then, Nie Fei used the aura to completely remove the medicine from the cold corpse's body, and then used it on the cold corpse again. After several attempts, Nie Fei concluded that if the medicine was used too much, it would take a long time for the cold corpse to attack, and the symptoms would be relatively mild. With the increase in the use of the drug, the duration of the attack will gradually decrease, and after reaching a certain amount, as soon as it is taken, the attack will occur immediately, and the symptoms will be extremely severe. The cold corpse is that when the symptoms of the cold corpse are extremely severe, both of its eyes become blood-red, its breathing is much heavier, and its limbs are constantly waving, showing an extremely irritable form.

For this kind of drug that can affect people's consciousness, Nie Fei also knows that if he uses a corpse puppet without divine consciousness to test, he will definitely not be able to test all the effects, and the best way is to find a real immortal cultivator to try.

Although Nie Fei had not yet grasped the final effect of this medicine, he had faintly felt in his heart that this medicine must be the best weapon against the powerful Iwafenggang.

This time, Nie Fei infiltrated the rock peak gang, and this medicine carried a lot. When he saw the three men, he sprinkled the medicine on their bodies to test the effect.

According to the reactions of the three people, the effect of this drug is to make people lose their minds, become manic and violent, and act recklessly. According to the last expression of the three people, this drug can completely stimulate the darkest things in people's hearts, dare to say things that they usually dare not say, dare to do things that they usually dare not do, and at the same time, people have become extremely bloodthirsty and violent.

Moreover, from the reactions of those three people, Nie Fei also discovered that the onset time of the drug was also related to the cultivation of each immortal cultivator. The medicine that Nie Fei used for the three of them was the same dose, but the two Qi refining stage cultivators immediately had an onset of medicinal effects, while the other monks in the foundation building stage had a later onset. Based on this, Nie Fei can control the onset time of the effect of the medicine on each person according to the amount of medicine he prescribes. This is also very important.

......

After Nie Fei fully summarized it, he gave this newly synthesized drug, according to the characteristics of the drug, a name, called Soul Separation.

Then, Nie Fei continued to sneak into the interior of Yanfeng Gang. In the process of diving inward, he found that there were obviously more people in Iwamine Oka Oka inside, and everyone used their aura and rushed to the same place.

Nie Fei sneered in his heart while avoiding these people. These people, after hearing the movement, rushed to the place where Nie Fei left just now. However, they are destined to work in vain, Nie Fei, as the initiator, has already left the place of the incident, even if these people go, facing the empty courtyard, they can only guess a rough idea, and the truth will never be known.

Nie Fei followed the trend of Yanfeng Gang and continued to sneak into the interior of Yanfeng Gang. Whenever he came to a courtyard that looked relatively large, he sneaked into it. The courtyard of this rock peak gang is very exquisite, and the courtyard where the disciples with relatively high status generally live must also be very spacious.

After Nie Fei experimented with the effect of Soul Separation, he had a plan in his mind, he wanted to use this Soul Separation to destroy Yanfeng Gang. It's not impossible, the effect of this soul dispersion is too terrifying.

Of course, with the implementation of this method, it is impossible to use the Soul Separation Disperse for everyone in Yanfeng Gang, as long as it is Nie Fei's Soul Separation Scatter, although there are a lot of preparations, it is impossible for everyone to use it. The best way is to use some of the more important disciples of Iwamineoka, these disciples are the backbone of Iwamineoka, if they are destroyed, Iwamineoka will definitely be self-defeating.

Therefore, Nie Fei went to find those disciples with relatively high status, and infiltrated those courtyards that seemed to be relatively large. Not to mention, basically every disciple in this kind of courtyard has a relatively high status, which can be seen from the clothing. The disciples in these courtyards are all wearing clothes with golden imprints, which is easy to tell.
