After Lin Xuan practiced the iron fist to the level of invincible iron fist, his master, Iron Fist Martial Saint, also appeared. Only then did Wu Yi realize that the Iron Fist Martial Saint is the reincarnation of the undefeated Martial Saint.

The Undefeated Martial Saint is an unparalleled warrior. He does not borrow any external force. Just a pair of iron fists is enough to reach the state of supreme half a step.

During the ancient war, his martial spirit was immortal. Although his body fell, he was still reincarnated into the world of kung fu.

Relying on the immortal martial arts intention, the undefeated Martial Saint made a comeback and still used a pair of iron fists to fight the world invincible.

The undefeated Martial Saint was consistent. After reaching the peak of the heavenly realm, he did not look for the supreme artifact that matched its attributes to break through to the supreme realm. Instead, he was constantly studying martial arts intentions, hoping to cultivate the Iron Fist skill to level 1,000 to break through to the supreme realm.

After reaching level 1,000 of this basic skill of sword mastery, the Holy Sword Incarnation successfully merged the Star Sword Wings and reached the supreme realm with this skill.

The Undefeated Martial Saint wanted to cultivate the first-level skill of Iron Fist to level 1,000, and also wanted to use this skill to reach the supreme realm.

After all, first-level skills are stronger than basic skills. If they practice to level 1,000, it is really possible to help the undefeated martial saint achieve their goals.

However, his cultivation difficulty is far greater than that of swordsmanship. The Undefeated Martial Saint has the previous foundation and has cultivated the Iron Fist to a level of 900. However, it is difficult to break through again.

So the Undefeated Martial Saint took another approach. He actually wanted to take Lin Xuan and enter the dark universe from the colorful light curtain, put himself to death, and force himself to break through.

The Iron Fist skill is also the skill that needs to be upgraded from endless battles. The undefeated Martial Saint was able to upgrade it to a level of 900, which was to fight with countless extraterritorial demons and realize it in countless life-and-death battles.

Wu Yi also tried to dissuade the undefeated Martial Saint, but in the end he did not stop it. At the extraordinary time and doing extraordinary things, Wu Yi finally let the demon master turn into the dark demon tower and integrate the undefeated Martial Saint and Lin Xuan into the dark universe.

Before entering the dark universe, Wu Yi transformed the undefeated Martial Saint into his apostle. He also asked him to return to the Starry Sky War Temple. In this way, he could also use the power of the soul furnace to refine the foreign demons in the realm.

The use of the soul furnace by the Invincible Martial Saint is only to use it to deal with the soul immortality of the Domain Extraordinary Demon, so as not to be entangled by it. He actually sealed up all the soul power after refining the Domain Extraordinary Demon, and never used any external force to enhance his own strength!

The unswerving martial arts spirit of the Invincible Martial Saint was also the main reason why he was able to reach his current realm. Lin Xuan also began to learn the Invincible Martial Saint, purely using a pair of iron fists to open up his own path.

The two of them entered the dark universe were Wu Yi's shadow incarnation and madman. The shadow incarnation killed countless dark monsters and extraterritorial demons in the bottomless abyss. His assassination and life-saving ability has been proven.

Wu Yi let the shadow transform into the dark universe, not only to ensure the safety of the undefeated Martial Saint and Lin Xuan, but to rescue them at critical moments. To a certain extent, it is also to let him detect information in the dark universe.

The dark universe has invaded many universes. In these cosmic eras, it has always been a fearful existence, and countless people have continued to fight against it.

But among all the records, there is really little understanding of the dark universe and related information, because few people will enter the dark universe.

The Dark Universe is the nest of the Domain Vulva Demons. When creatures from other races enter the Dark Universe, they will be like fireflies in the darkness. They will be besieged by countless Domain Vulva Demons.

In the dark universe, we are facing a terrifying creature like the foreign demon of the realm of the soul. Even the Immortal God King will sooner or later fall and be tortured to death.

There was also a peerless strong man who tried to enter the dark universe to investigate the situation, but in the end there was no news. He was either surrounded and killed or parasiticly possessed by the foreign yin demons of the domain. The information transmitted back was also wrong.

This makes it possible for many cosmic eras to understand the dark universe in only a few understandings. Even how vast the dark universe is, in addition to the foreign demons, there are no information on whether there are other races, etc., in addition to the domain.

The shadow transforms into the dark universe and can assassinate the peerless powerful people among them while inquiring about various information about the dark universe, so that Wu Yi can make targeted arrangements.

The shadow incarnation can use the power of the soul furnace and can also escape at any time, making it the best candidate to spy on news.

The reason why the madman followed them into the dark universe is related to the madman's pair of demonic hands.

This pair of demon hands comes from the bloodthirsty demon god, but in fact, the bloodthirsty demon god is not the original master of the pair of demon hands.

After the strength was increased to the holy level, the madman had discovered the strangeness of this pair of demon hands, which came from a supreme powerhouse, and this supreme powerhouse incorporated a pair of supreme artifact-level claws into the supreme realm that he upgraded to.

Later, after the supreme power fell, his arms were left behind. After thousands of disasters, they were obtained by the bloodthirsty demon god.

The bloodthirsty demon god relied on the hands of this pair of demons and became one of the top strongest among the ancient demon gods.

This pair of demon hands can also be regarded as a supreme artifact. The madman's ability to obtain this pair of demon hands was also an adventure by chance.

The faster the madman's strength increases, the more he discovers the power of the demonic hands. After the degree of fit increases, the madman finds that in order for the demonic hands to show all their power, he needs to enter the dark universe.

The fall of the supreme powerhouse with the demon's hand is closely related to the dark universe. The madman sensed that there was a force in the dark universe attracting him, so the madman entered the dark universe together.

When the four of them entered the dark universe together, Wu Yi found that their connection with him was almost cut off. Wu Yi could only vaguely sense that the shadow incarnated into a world full of dark demonic energy.

The environment in the dark universe is very extreme, and its interior is filled with dark demonic energy, which is only suitable for the survival of dark monsters and foreign demons.
