For any magic weapon, the turbid air in the world is the number one enemy, because the turbid air in the world can damage the spirituality of the magic weapon, while ordinary magic weapons do not have such concerns. In order to eliminate the damage caused by the turbid air in the world, practitioners generally put important magic weapons in close proximity and nourish them with their natal true essence at any time. This can not only improve the degree of compatibility between the magic weapon and themselves, but also protect the magic weapon at all times.

Although the piece of treasure fragment inlaid by someone at the front of the dagger is the treasure of the heaven and earth in the prehistoric period, it has been thousands or ten thousand years since it has been wandering in the secular world. Even after so many years, even if the secular world has obtained this piece of fragment, it cannot be refined into other magic weapons, and there is no prehistoric energy to nourish this piece. In this way, the fragment is eroded by the turbid air of the red dust and is beyond recognition. Most of the power in the fragment has long disappeared, and the remaining power is only the power possessed by the original material of the fragment.

Because of this, Xu Changqing could only infer from the power of the fragment itself that this treasure was made of a treasure made of innate essence gold and spiritual material. Although there were not many spiritual treasures that could be refined with innate essence gold and other spiritual materials in the ancient times, there were more than ten, which was still publicly available. There were also a large number of such spiritual treasures that were not disclosed, and there were at least thirty in total. Therefore, Xu Changqing could not judge what treasure was when the fragment was refined from the fragments.

There was only a very ordinary little detail that gave Xu Changqing some tips, allowing him to reduce the prehistoric innate spiritual treasure corresponding to this small piece to three. The person who is now using this prehistoric treasure fragment to cut the iron sheet is not a cultivator. He is just an ordinary person, and he did not use any magic power when using this piece, just like using ordinary weapons to use it. Among the such prehistoric spiritual treasures made with innate gold sperm that Xu Changqing knew, there were only three spiritual treasures that could be used by people without any magic power and would not be subject to its backlash. Among these three spiritual treasures, one of them could be related to the prehistoric innate gods he was looking for on this trip. This treasure is the Demon Slaying Sword.

Regarding the relevant information about the Demon-Slaying Sword, Zhen Yuanzi's incomplete memories are also very rare. I don't know if these memories are in the lost part or because Zhen Yuanzi deliberately forgets these memories. The Demon-Slaying Sword is also very famous in the ancient prehistoric world. Even in some remaining classics in the Three Realms of Kunlun, it is only that neither Zhen Yuanzi's incomplete memories nor the records in the Prehistoric books mentioned who refined this treasure.

From its appearance to its final disappearance, this treasure has always been in the hands of the prehistoric human race. It is also the strongest reliance used by the prehistoric human race to fight against the demon race. The biggest feature of this treasure is that it can be used by mortals without any magic power. According to Zhen Yuanzi's memory, no matter how high the cultivation level of the demon race is, its soul will be withered. If the qi and blood are exhausted, it will inevitably enter the five declines of the heavenly beings and the soul will dissipate within one year.

It is precisely because this treasure completely restrains the demon clan, that the demon clan of the prehistoric times has always wanted to take this treasure away from the human race and destroy it. But the problem is that as long as the demon clan approaches this treasure, the strength on its body will be limited. The closer the distance, the greater the limit. Even a demon clan in the realm of Daluo Golden Immortal, after holding this treasure, his strength will be limited to the state of an ordinary person. This also makes the demon clan hate this treasure to the core, but he is helpless, and can only spread his eyes and find out who made this treasure.

The fact that the demon clan investigates the refiners of the Demon Slaying Sword is a big deal in the ancient prehistoric world. Although there is no evidence, most prehistoric creatures think that this matter should be related to the innate gods. Due to the ancient dragon clan, the relationship between the innate gods and the prehistoric demon clan is very bad, and there are only a handful of people with targeted prehistoric innate spiritual treasures such as the Demon Slaying Sword in the entire prehistoric world, and at least 80% of these people are innate gods. This speculation is not only recognized by most of the creatures in the prehistoric world. Even many people inside the innate gods think this is the case.

Zhen Yuanzi had secretly investigated this matter because he was curious, but unfortunately he found nothing in the end. However, like most people on the prehistoric land who were concerned about this matter, he also felt that the Demon-Slaying Sword originated from the hands of the innate gods. This speculation was not an imagination out of thin air. Instead, he felt a trace of extremely weak innate gods from the Demon-Slaying Sword through a unique method.

In fact, Xu Changqing was very sure that the fragment was the fragment of the Demon-Slaying Sword, because the final destination of the remaining two treasures with the same characteristics and materials were clearly recorded in Zhen Yuanzi's memory, and this record would never go wrong. Among the three treasures of the Demon-Slaying Sword, only the Demon-Slaying Sword disappeared as mysteriously as it appeared. Until the Great Demon-Slaying Sword was broken, no one knew its final whereabouts.

Just as Xu Changqing recalled the memories related to the fragment in his mind, the masked man had already dug a hole in the roof of the car that could be drilled by one person. The others around him surrounded him and were about to drill into the car from this entrance. The two practitioners who used the Sun God Flag and the Night God Flag inevitably shifted their attention to the dug entrance, and their always vigilant hearts couldn't help but relax a little.

Seeing the opportunity appear, Xu Changqing lightly tapped the roof of the car with his toes, and his whole person turned into a black shadow and rushed towards the practitioner who was closest to him, holding the Night God Flag. As he passed through the sealing realm, a layer of weak magic power instantly appeared around his body. This layer of weak magic power was surprisingly in line with the sealing realm arranged with the Night God Flag and the Sun God Flag, even surpassing the two practitioners who were holding the flag. This combination of magic power made the sealing realm not only not startled any abnormal movements due to the intrusion of outsiders, but instead integrated it into the sealing realm like welcoming his family.

The moment he entered the sealing world, Xu Changqing appeared next to the practitioner holding the Night God Flag. Before the other party reacted, he slashed the other party's back neck with a palm. At the same time, he reached out and held the Night God Flag in his hand, injected a magic power, and then used the magic trick to directly seize the control of the Night God Flag.

Xu Changqing's series of actions were silent like flowing water, and in the blink of an eye, the process did not even cause any abnormality in the process of seizing the Night God Flag control, which also made no one else around him noticed that the person who controlled the Night God Flag had changed.

After controlling the Night God Flag, Xu Changqing injected a magic power into the magic weapon in his hand, and as the magic power was injected into the Night Game God Picture on the banner, sparkling with silver light.

The main spirit in the Night God Flag is always nurtured by the Tianshi Mansion and will only react to the unique magic power of the Tianshi Mansion. This is also an obstacle that the Tianshi Mansion has made to prevent the magic weapon he has worked hard to refine is used by others and backfire him. However, this obstacle is useless in the face of Xu Changqing's millions of incarnation magic powers. Xu Changqing's imitation of the Tianshi Mansion easily deceived the Night Walking God in the flag and let him act according to his orders.

In the dark night, the light of the flag flag was extremely eye-catching, and everyone looked at Xu Changqing at the same time. Before they could see Xu Changqing clearly, eight rays of light shone out from the night god flag and rushed towards the eight people. Seven of the eight rays of light were unhindered and entered the foreheads of seven ordinary warriors. The seven people looked dull and looked dazed as if their souls were caught. The remaining cultivator did not have time to react in the sudden attack, but the Sun God Flag in his hand was automatically shining with a phantom of the Sun Travel God, trying to block the light. The moment the two magic powers of the same origin collided in the air, they almost transformed into two vague phantoms of gods, attacking each other like military generals on the battlefield.

"Who are you?" The Tianshi Mansion sect who had just woken up at this time looked at Xu Changqing with horror. While questioning loudly, he quickly waved the flag in his hand. Every time he waved it, a light rushed out and injected into the shadow of the Riyou God, making his breath condensed and his advantage increased by one point.

The ability of this Tianshi Mansion sect was not beyond Xu Changqing's expectations. Instead, the Sun God Flag became an accident. He did not expect that the Sun God Flag and the Night God Flag were not refined at the same time. The Sun God Flag had definitely been in the Tianshi Mansion for hundreds of years. The main spirit in the flag had already produced spirituality, which was almost equivalent to the real earth god. He judged the ability of the Sun God Flag completely based on the ability of the Night God Flag in his hand, so that he failed to do his best this time.

However, even if an accident occurs, it will not affect the result. Although the Sun God Flag is powerful, the person who holds the flag is too bad. He only knows how to activate magic power and strengthen the gorgeous but unreal Sun God Vision statue, but he does not know how to use this magic weapon at all.

I saw that Xu Changqing did not urge the flag in his hand to inject magic power into the transformed Night You Shenxu statue. Instead, he shook the flag and directly controlled the Night You Shenxu statue to dissipate its body. All the magic power turned into more than ten more subtle paths. The dim light bypassed the shadow of the Sunyou Shenxu statue in front of him and rushed directly towards the protected flag-holder.

The phantom of Yeyou God suddenly disappeared, causing the attack of the phantom of the Riyou God to fall into the air. Before the flag-holder controlled the Riyou God to return to defense, the dozens of dim lights had already been placed on the disciple of the Tianshi Mansion, making him stand in place as lost as others.
