After Lin Xuan cultivated the Iron Fist to the invincible realm of the Iron Fist, his master Iron Fist Martial Saint also appeared, and Wu Yi knew that the Iron Fist Martial Saint was actually the reincarnation of the Undefeated Martial Saint.

The Undefeated Martial Saint is a peerless martial artist, who does not borrow any external force, and with a pair of iron fists alone, it is enough to reach the realm of half-step supreme.

In the ancient war, his martial intent was immortal, and although his body fell, he was still reincarnated in the world of kung fu.

Relying on that immortal martial intent, the undefeated martial saint successfully made a comeback, still with a pair of iron fists, fighting invincible opponents all over the world.

The undefeated Martial Saint has always been consistent, after reaching the peak of the Heavenly Rank Realm, he has not been looking for a supreme artifact that matches its attributes to break through to the supreme realm, but is constantly studying martial intent, wanting to cultivate the skill of Iron Fist to level 1,000 to break through to the supreme realm.

After the basic skill of swordsmanship mastery reached level 1,000, the Holy Sword Incarnation successfully fused the Star Sword Wing with this skill and reached the supreme realm.

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

After all, the first-order skill is more powerful than the basic skill, and if it is cultivated to level 1,000, it is really possible to help the undefeated martial saint reach the goal.

However, the difficulty of his cultivation is far better than that of swordsmanship, and the undefeated martial saint has the previous foundation, and he has cultivated the iron fist to the realm of nine hundred levels, but if he wants to break through again, it is extremely difficult.

So the Undefeated Martial Saint found another way, he actually wanted to take Lin Xuan with him, enter the dark universe from the colorful light curtain, and put himself to death to force himself to break through the realm.

The skill of Iron Fist is also the skill that needs to be upgraded the most from endless battles, and the previous undefeated martial saint can raise it to the realm of nine hundred. It is to have fought with countless extraterritorial heavenly demons, and have an epiphany in countless life and death battles.

Wu Yi also wanted to dissuade the undefeated Martial Saint's risky behavior, but in the end, he still didn't stop it, and did extraordinary things at an extraordinary time. Wu Yi finally let the Demon Lord incarnate and preside over the Dark Demon Tower, integrating the Undefeated Martial Saint and Lin Xuan into the Dark Universe together.

Before entering the Dark Universe, Wu Yi also transformed the Undefeated Martial Saint into his own apostle, and also let him return to the Starry Sky War God Temple, so that he could also use the power of the Soul Furnace to refine the extraterritorial Yin Demon.

The Undefeated Martial Saint's use of the soul furnace is only to use it to deal with the soul immortality of the extraterritorial yin demon, so as not to be entangled by it, he actually sealed the soul power after refining the extraterritorial demon demon, and never used any external force to improve his own strength!

This unwavering martial spirit of the undefeated martial saint. It was also the main reason why he was able to reach his current realm, Lin Xuan also began to learn the Undefeated Martial Saint, and purely opened up his own path with a pair of iron fists.

Entering the dark universe with the two of them, there was also Wu Yi's Shadow Avatar and the Madman, the Shadow Avatar killed countless dark monsters and extraterritorial heavenly demons in the bottomless abyss, and its assassination and life-saving abilities have been proven.

Wu Yi let the Phantom Shadow incarnate into the Dark Universe, both to ensure the safety of the Undefeated Martial Saint and Lin Xuan, and to rescue them at a critical moment. To a certain extent, it is also to allow him to scout the information in the dark universe.

The Dark Universe has invaded many universes. In these cosmic times, it has always been a formidable existence, and countless people have come forward to fight against it.

However, in all the accounts, there is very little knowledge and related information about the dark universe, and that is because very few people will enter the dark universe.

The Dark Universe is the lair of extraterrestrial demons. As soon as creatures of other races enter the dark universe, they will be besieged by countless extraterritorial demons like fireflies in the darkness.

Fighting alone in the dark universe, facing a terrifying creature with immortal soul characteristics like the Extraterrestrial Yin Demon, even if it is an immortal god king. Sooner or later, they will fall and be grinded to death.

There have also been peerless powerhouses who tried to enter the dark universe to investigate their situation, but in the end there was no news, either they were besieged and killed, or they were parasitic possessed by extraterritorial demons, and the information transmitted back was also wrong.

This makes it possible to know nothing about the dark universe in many cosmic eras, and even how vast the dark universe is, whether there are other races besides extraterritorial demons, and so on, have not been probed.

The shadow incarnated into the dark universe, and while assassinating the peerless powerhouses in it, he could probe all kinds of information in the dark universe, so that Wu Yi could make targeted arrangements.

The Shadow Avatar can use the power of the Soul Forge and can escape at any time, making it the best candidate to spy on the news.

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

This pair of demonic hands came from the bloodthirsty demon gods, but in fact, the bloodthirsty demon gods were not the original owners of this pair of demonic hands.

After the strength was raised to the Holy Realm, the madman had already discovered the strangeness of this pair of demonic hands, which came from a supreme powerhouse, and this supreme powerhouse was the supreme realm that he had raised to by integrating a pair of supreme artifact-level claws into his body.

Later, after the fall of this supreme powerhouse, one of his arms was left behind, immortal after thousands of tribulations, and was obtained by the bloodthirsty demon god.

The Bloodthirsty Demon God relied on the hands of this pair of demons and became one of the most ranked powerhouses among the ancient demon gods.

This pair of demonic hands can also be considered a supreme artifact, and the fact that a madman can obtain this pair of demonic hands is also an adventure by chance.

The faster the madman's strength increases, the more he discovers the strength of the demonic hand, and after the fit improves, the madman discovers that in order for the demonic hand to show its full power, it needs to enter the dark universe.

The fall of the supreme powerhouse with the hand of the devil is closely related to the dark universe, and the madman senses that there is a force in the dark universe that attracts him, so the madman will enter the dark universe together.

When the four of them entered the dark universe together, Wu Yi found that their connection with himself was almost severed, and Wu Yi could only faintly perceive that the shadow incarnation had entered a world full of dark demonic energy.

The environment within the dark universe is very extreme, and its interior is full of dark demonic energy, which is only suitable for the survival of dark monsters and extraterritorial demons.

In the dark universe, the dark monsters are creatures that don't have much reason, they only know destruction and destruction, and live in a reckless land without civilization. (To be continued......)
