"It's so rich, how many creatures have to be slaughtered to gather such a strong evil aura, fierce soldiers!

Li Mu looked at the four swords of the Immortal in front of him, and couldn't help but take a dozen steps back with a chill down his spine, there are many evil cultivators in the cultivation world, and they will also use their spiritual treasures to slaughter many living beings to enhance the evil qi of their own spiritual treasures, evil qi is an invisible substance, and it is not difficult to make it appear, as long as it kills people.

Any spiritual treasure, every time you kill a person, a trace of evil qi will be condensed on it, as the number of killings increases, the evil qi will become more and more intense, when the number of people killed reaches a certain number, the evil qi will be obviously 'exposed', in fact, in the cultivation world, not only spiritual treasures, but even people are the same.

With the increasing number of killings, people's bodies will also be contaminated with evil qi, which can be used through some demonic methods, but if the evil qi is too heavy, it will also have great damage to the human body, and people who have been entangled by evil qi for a long time can easily fall into the devil's way.

The demon path referred to here does not refer to the demon cultivator who cultivates the demon path exercises, but the real inner demon, becoming a walking corpse that has lost his mind and only knows how to kill people.

"Why are these four swords so familiar, where have I seen them... Yes, the statue of Tongtian Daozun in the Taixuan Hall is standing in his hand, isn't it just four swords with such a heavy aura, but after all, it is a statue, not a genuine product, even if the refiner 'spent' a lot of effort when refining, it cannot be compared with these four swords. ”

Li Mu suddenly remembered the statue of Tongtian Daozun he saw when he entered the Taixuan Palace, and there were also four swords in the hands of the statue, although the sword standing in the hand of the statue was a little rough, but it was very similar to the four swords of Zhuxian floating in the air in front of Li Mu at the moment.

"It shouldn't be the spiritual treasure of Tongtian Daozun, no matter how you say it, he is also the legendary ancestor of the Dao 'Gate', and it is rumored that he has entered the realm of immortal Dao, even if the rumors are a little exaggerated, then he is at least an emperor-level figure, and although these four swords are extremely evil, there is still a distance from the imperial soldiers, at most they are just four holy soldiers!"

Li Mu looked around the four ancient swords in mid-air, and he concluded that the four swords of the Immortal were related to Tongtian Daozun, but they were definitely not Tongtian Daozun's spiritual treasures, because the level was not enough.

After hesitating for a long time, Li Mu tried to probe out a trace of spiritual sense towards the body of the four swords of Zhu Xian, but when he poked out his spiritual sense, he immediately regretted it, because as soon as his spiritual sense approached the four fierce swords, it was immediately eroded by the rich evil qi emanating from the sword body, and this rich evil qi also surged towards his eyebrows along Li Mu's spiritual sense.

The spiritual consciousness was eroded by the evil qi, Li Mu's frightened soul was scattered, and he didn't have time to feel sorry for his spiritual consciousness, so he directly cut off the part of the spiritual consciousness that was eroded by the evil qi, abandoned it, and was eroded by the evil qi.

But the four swords of Zhu Xian are different, the evil qi contained in them is too heavy, Li Mu knows that as long as he is entered by this evil qi, his mind will immediately be lost, and when the time comes, it will be fatal, and he will be controlled by the evil qi, and he will be reduced to a walking corpse that only knows how to kill people.

"The real murderer, it's not an ordinary murder, even the spiritual sense can't get close, this is given to me for nothing, it's useless, any spiritual treasure is not controlled by spiritual consciousness, it can't exert any power at all, not to mention that this is still an ancient magic weapon, and you can turn the spirit to convert the vitality in the body into spiritual energy to try to see if you can urge it, and the same as the 'chicken' ribs!"

After he was almost killed by the four swords of the Immortals, Li Mu basically lost interest in these four fierce swords, although this is a saint-level killing weapon, and there are four in total, but if he can't use it, it will mean nothing to him at all.

Just when Li Mu didn't know what to do with the four fierce swords, suddenly, the blood light on the surface of the four fierce swords in mid-air all dimmed, from the flickering state of demonic blood light, into four rusty rusty swords, and fell, 'inserted' into the ground made of unknown 'jade' stone.

"Huh, I actually restrained the evil aura that was 'exposed' outside, and it looks like a mortal iron, which is a bit weird!"

As the four ancient swords fell to the ground, Li Mu slowly moved closer to the four swords of Zhu Xian, after he was sure that these four swords were not in any danger, he tried to touch the hilt of the trapped fairy sword with his hand, and what made Li Mu breathe a sigh of relief in his heart was that this touch 'touch' did not let him suffer any damage or be repelled.

Seeing that his touch was not rejected in any way, Li Mu tried to inject the True Yuan power into the Trapping Immortal Sword, but to Li Mu's surprise, with the injection of his True Yuan power, the Trapping Immortal Sword did not react at all.

After thinking about it for a while, Li Mu thought that this magic weapon in ancient times was to be driven by aura, so he tried to cast a spiritual transformation again, and transformed the true yuan power in his body into aura, and injected it into the trapped immortal sword again, but the result was the same as injecting the vital energy, and the trapped immortal sword still did not react at all.

"That's not right, this spirit transformation is recorded in the 'Mixed Heaven' Jade Jane, there is no reason why it will not be effective, or can these four fierce swords not be activated by normal means at all!"

After Li Mu tried to inject Yuan Qi and Spiritual Qi to no avail, he sat down on the spot for some unknown reasons, and this type of method 'door' of Turning Soul Determination is not very secret magical power in the cultivation world, on the contrary, it is widely spread, and its function is very simple, that is, to transform the energy of Yuan Qi into spiritual energy, which is used to drive some ancient magic weapons, or to perform some ancient secret techniques.

Whether it is aura or vitality, it is a kind of energy between heaven and earth, although the composition of the elements is somewhat different, but the essence is still the same, it can be transformed through the similar method 'gate' of the transformation of the spirit, but the different transformation method 'gate', there is a difference in the speed of transformation and the amount of spiritual energy transformed, like Li Mu's transformation of the spirit decision, which is the 'mixed' Tianhe Heavenly Demon Sect for generations, and it can be regarded as a relatively advanced method of spiritual energy transformation.

Although he couldn't test the magic of these four fierce swords, Li Mu didn't intend to let it go, he tried not to use any vitality or aura, and directly used the four swords of Zhu Xian as mortal soldiers, for which Li Mu also took out a few spiritual treasures that were not of great use to him, and compared them with the four swords of Zhu Xian, but the results all self-destructed, and they were all cut in two.

This made Li Mu finally feel a little comforted in his heart, not to mention the magic of the four fierce swords, just talking about their sharpness, it is really rare in the world, at least Li Mu except for the slashing Qianqiu on his body, even the slashing immortal commander did not dare to take it out and compare with these four fierce swords.

"My father is finally a sword cultivator in the transcendent realm, and his attainments in the field of kendo are not known to be many times stronger than mine, and it will be a good choice to give these four swords to him when the time comes!"

Li Mu took out four long 'jade' boxes, put all the four swords of Zhuxian into the 'jade' box, and finally sealed all the 'jade' boxes with a spirit talisman, in order to be on the safe side, Li Mu took out a storage ring alone, and put the four 'jade' boxes into the storage ring separately, thinking that he would give these four swords to Li Chongtian in the future.

After dealing with the four swords of Zhuxian, Li Mu tried to release the god-killing insect into several other bronze giant tripods, but this time Li Mu's actions did not cause any abnormalities, Li Mu had to smile awkwardly, he laughed that he was too greedy.

Seeing that Leng Qicheng hadn't woken up yet, Li Mu put his eyes on the stairs in the corner not far away, this staircase was the entrance to the seventh floor of the Tianzi Attic, Li Mu thought that he had nothing to do anyway, and took a step towards the seventh floor.

When Li Mu walked through the stairs to the entrance of the seventh floor, looking at the scene in front of him, he didn't know whether to laugh or cry, the entrance of the seventh floor was actually the same as the entrance of the first floor, and there was also a gray 'color' forbidden light curtain to protect it
