"Go!"

Seeing the Qianxuan Sword burst out with unprecedented might, Mu Chen's eyes lit up, and he suddenly pinched out a drop of essence blood from between his fingers, flew towards the Qianxuan Sword, and blended into it.

As his hands sealed, an invisible force instantly poured into the Thousand Xuan Sword, forming the most intimate connection with the Thousand Xuan Sword.

At this moment, Qianxuan Sword was like another doppelganger of him, and he could command it at will as long as he wanted to.

"Whew!"

With the success of the blood refining, the power of the Qianxuan Sword became even more powerful, and the nine great forces rose to the sky, causing the earth to tremble and the sky to change greatly.

This power, even if it is stronger than the Golden Immortal, is even more than that.

The mad immortal who had been sitting on the side, and didn't know when he took out a wine gourd and kept drinking, his eyes narrowed suddenly, and he looked at this fairy sword incredulously.

"This!

His face was full of horror, and he muttered to himself, "Could this be the legendary artifact?"

At this moment, the nine great forces that rose to the sky on the body of the Thousand Xuan Sword had already stirred the heavens and the earth, and huge whirlpools appeared, attracting the attention of everyone in the entire Ten Thousand Dao Heavenly Palace.

I have to say that this power is really too powerful, more than ten times stronger than when Mu Chen crossed the tribulation.

The power of heaven began to descend, and the whole world was completely plunged into darkness.

The Qianxuan Sword seemed to be aware of it, and suddenly let out a sword groan, and then soared into the sky, piercing through the void, and came to the Nine Heavens and Clouds.

"What's that?"

Seeing that the entire Heavenly Palace was plunged into endless darkness, countless people rushed out one after another, looking at the nine-colored divine light that rose to the sky, their faces full of horror.

"Could it be that some great power is about to cross the catastrophe?"

Someone speculated.

"No, look, it's a sword, a fairy sword!"

Immediately, someone saw the body of the nine-colored divine light clearly, and immediately shouted excitedly.

"It's really a sword, a sword can also attract a heavenly calamity, is it the legendary immortal sword above the third grade?"

"I'll go, who is so powerful, he actually refined the legendary supreme immortal sword of more than three grades!"

The entire Heavenly Palace was completely shaken, and even the Ten Thousand Dao Heavenly Maidens were attracted by the supreme power of this sword.

"Heavenly Maiden, this, could it be that the inheritance of some powerful person is in the world, triggering the Heavenly Tribulation?" Ruyi's face was full of surprise, and she stood beside the Ten Thousand Dao Heavenly Maiden and said.

"This is not the inheritance of the present world, although the inheritance of many ancient powers in the present world will often have some mysterious exercises and magic weapons that will cause the heavenly tribulation, but it will never be so strong. This is a newly refined immortal sword!" Wan Dao Heavenly Maiden frowned slightly and said in a deep voice.

"No, this fairy sword seems to have flown out from the refining workshop, could it be that someone in our Heavenly Palace can refine such a magic weapon?"

The Ten Thousand Dao Heavenly Maiden slowly closed her eyes, and her powerful divine sense enveloped the entire sky, and she got the answer she wanted in an instant.

"That's right, it was refined by the people of the Heavenly Palace, I didn't expect this Mu Chen to have such attainments in the refining weapon, it seems that I really underestimated him!" Wandao Heavenly Maiden said in a deep voice.

"What, is Mu Chen's son?" Ruyi was taken aback, never expecting that this magic weapon would be from Mu Chen's hand.

As he spoke, in the void, under the endless darkness, I saw the tide of endless darkness turning into a torrent surging by.

Wherever the tide passed, a strong corrosive gas corroded the sky into a vacuum.

This dark power, which can corrode even the sky, directly wrapped the Qianxuan Sword in it, and there was a "bang" sound in an instant, as if it was about to completely corrode the Qianxuan Sword.

"This! What kind of catastrophe is this, this is clearly the dark tide!"

When everyone saw this scene, they couldn't help but be stunned, and their faces were speechless.

Countless people have never seen a dark tide appear in the Heavenly Tribulation.

Even Mu Chen couldn't help but be a little dumbfounded at the moment.

He knew that when the Thousand Xuan Sword was born, it would definitely go through the baptism of the Heavenly Tribulation.

This Heavenly Tribulation is likely to destroy the Thousand Xuan Sword, but it has to go through it. First, no one can avoid the catastrophe, and he can't avoid it if he wants to.

Second, only the Thousand Xuan Sword that has experienced the baptism of the Heavenly Tribulation can be regarded as the real Thousand Xuan Sword, and in terms of power, there will be an unprecedented increase.

But this catastrophe came, and the result turned out to be a dark tide, which was a bit beyond Mu Chen's expectations.

"Mu Chen, what are you still talking about, don't hurry up!"

Just when Mu Chen was stunned, the voice of the system came suddenly, and he hurriedly shouted.

"What?" Mu Chen was stunned, although this Qianxuan Sword was his blood refining magic weapon and could be called his doppelganger, but the Qianxuan Sword crossed the catastrophe, it didn't seem to be his turn to help!

"Hey, you can't see it, this is the Dark Tide, the most powerful Dark Tide, far from being comparable to the Dark Tide you experienced in the Six Labyrinths! This is the origin of the Dark Power, it appears at this moment, if you don't hurry up and use it to strengthen your Dark Primal God, when?" the system was speechless.

"You let me break into the Heavenly Tribulation and extract the Origin Power of the Dark Tide?" Mu Chen frowned, this was a big taboo in the Tribulation.

You must know that under the catastrophe, no one is allowed to break in, otherwise the power will be doubled. If it weren't for this, when others crossed the tribulation, they found a master to help, who would have failed to cross the tribulation?

"Mu Chen, are you stupid, you and Qianxuan Sword have already experienced blood refinement, in the final analysis, Qianxuan Sword is you, you are Qianxuan Sword, you and Qianxuan Sword are one, Qianxuan Sword is tribulated, you join in, there is no problem at all. And this is a once-in-a-lifetime opportunity, even if there is a problem, it's a big deal to fight the Thousand Xuan Sword, you should also hurry up and take this opportunity to extract the Dark Origin!" the system said in a very helpless tone.

"That's right!"

Because of the relationship between Qianxuan Sword before, Mu Chen didn't think about it so much, but at this moment, he reacted without any hesitation, and as soon as his feet moved, he immediately rose to the sky, turned into a streamer, and came to Qianxuanjian's side.

"Hey, Mu Chen, what are you going to do?"

Seeing this, the red pine fairy was taken aback and hurriedly shouted.

It's a pity that at this moment, Mu Chen has already come to Qianxuanjian's side, and he is in the void of thousands of miles, and he can't hear what she says at all.

As the system said, the Thousand Xuan Sword was his blood refining magic weapon, and he joined the Heavenly Tribulation confrontation without any problems.

Everyone below couldn't help but be surprised when they saw Mu Chen suddenly break into the Heavenly Tribulation.

Throughout the Heavenly Palace, there were bursts of exclamations from all over the place.

Under their gaze, they saw that on Mu Chen's body, a primordial spirit suddenly rushed out, extremely black, releasing the power of endless devouring, and the dark tide was instantly stirred by a huge whirlpool, constantly devouring it.

"This ...... Who is this man, who is he devouring the power of the Dark Tides?"

Everyone was taken aback, and their faces were full of shock.

Although there are also many people in the Ten Thousand Heavens who cultivate the power of darkness, this dark tide is the source of darkness, and those who dare to devour it directly, there are almost no such people in the entire Ten Thousand Heavens.

As a result, Mu Chen's appearance instantly reversed everyone's thoughts.

Under their gaze, as Mu Chen continued to devour this dark power, a strong dark vortex also erupted on the Qianxuan Sword, and it was like the master Mu Chen, who began to devour this dark power strongly.

The devouring of Qianxuan Sword and Mu Chen, as if it had issued the strongest provocation to the Heavenly Dao, I saw that the entire heaven and earth were shaken, copying thousands of miles, surging forward, carrying the momentum of stormy waves, almost smashing Mu Chen and Qianxuan Sword.

"Whew!"

However, in the face of this even more turbulent dark tide, the whirlpool that erupted on Mu Chen and Qianxuan Sword was even more intense, and it devoured even more rapidly.

The entire dark tide has completely become a place of trial for one person and one sword.

Time passed little by little, and after three hours, the dark tide finally receded.

However, at this time, between heaven and earth, a thousand rays of light suddenly erupted, which was in stark contrast to the previous dark tide.

Under this kind of light, Rao is countless immortals, all of whom are blind, and the strong power of light burns the flames of light, burning to Mu Chen and the Qianxuan Sword.

Under the power of this bright flame, all the people in the Heavenly Palace thousands of miles below felt the unprecedented heat.

"This! This is the legendary Bright Flame of Light!" Someone suddenly exclaimed.

"It's dead, this Bright Saint Flame is an existence with the same name as the three holy fires, it appears at this moment, don't say it's just an immortal weapon, I'm afraid that even the artifact can be melted, this person has a sword, it's miserable!"

Someone muttered, and couldn't help but feel sorry for a while.

They witnessed the birth of a supreme immortal sword, but they were also destined to witness the destruction of a supreme immortal sword.

But just when everyone thought so, they saw that in the void, two huge whirlpools burst out.

The two light vortexes, like the previous Dark Devouring, were constantly extracting this powerful Light Sacred Flame.

"This!"

Everyone was stupid, and they all mobilized their strength to their eyes, staring at this scene deadly. Under their gaze, the fate of this Bright Saint Flame turned out to be the same as the previous dark tide, devouring as much as it wanted, not only could not hurt that person and sword, but instead became the nourishment of that person and sword.

Another three hours passed, and the Bright Flame gradually receded.

Although there is also a saying that immortal weapons can cross the tribulation, no one has ever heard of the saying that a fairy sword can induce two major heavenly tribulations in a row.

In their opinion, this immortal sword has survived the two major heavenly tribulations at the same time, which is already unprecedented, and after these two major heavenly tribulations, the Thousand Xuan Sword should be regarded as formed.

But at this moment, Tianwei descended again, and under the vast Tianwei, the thunder was surging, rolling in, endless thunder and lightning, turning into a river, directly besieging Mu Chen and Qianxuan Sword.

Seeing this, Mu Chen's eyes narrowed slightly, his heart moved, and said: "Heavenly Thunder Tribulation, why are the generals of these Heavenly Tribulations so the same as the order of the nine attributes on the Thousand Xuan Sword, could it be that this Thousand Xuan Sword Tribulation must go through the baptism of the Nine Attribute Heavenly Realm?"

Thinking of this, Mu Chen hurriedly shouted: "System, quickly prepare an innate primordial spirit for me, if it is really a gathering of the nine major attributes, my nine primordial gods should be cultivated today!"

At the beginning, after cultivating the five great Xuan Infants, when he came to Wanfa Heaven and achieved the Earth Immortal, Mu Chen had already condensed the five great primordial gods, namely the Heavenly Thunder Primordial God, the Gangfeng Primordial Spirit, the Dark Primordial Spirit, the Bright Primordial Divine and the Gengjin Primordial Spirit.

Later, in the Heavenly Immortal Tribulation a few days ago, he successively experienced the Heavenly Fire Tribulation, the Heavenly Water Tribulation, the Kuimu Thunder Tribulation, etc., so he condensed the Weak Water Primordial God, the Heavenly Fire Primordial God and the Kuimu Primordial Spirit, and at this moment, he already contained the Eight Great Primordial Gods in his body.

Among the eight primordial gods, the rest of the primordial gods have basically devoured the power of the Heavenly Tribulation now, but Gengjin primordial gods have not, which seems to be a lot weaker. Now, if it was really the Nine Attribute Heavenly Tribulation that came, he would never let go of this opportunity to forge the Gengjin Yuan God.

And he also has to find a way to get the last primordial god, the thick earth primordial god, to withstand the suction of the heavenly tribulation.

When the time comes, the nine primordial gods will gather, and they are all primordial gods who have experienced the suction of the heavenly tribulation, and he believes that even if he crosses the level of battle, he will have few opponents in the Xuan Immortal realm.

When the system heard this, he said in a deep voice: "Reasonable!"

The next moment, the two innate primordial spirits merged into Mu Chen's body, and Mu Chen began to condense the two primordial spirits while devouring the power of the heavenly thunder with the Thousand Xuan Sword.

Time kept slipping, just as Mu Chen had guessed, the advent of this heavenly tribulation was completely based on the nine attributes of the Thousand Xuan Sword.

First, it experienced the dark tide of the dark attribute, then the light of the light attribute, and then the thunder of the thunder attribute, followed by the baptism of the power of the wind, and the power of the five elements.

When the last two major heavenly tribulations, the power of the thick earth and the power of Gengjin, came, Mu Chen did not hesitate to release his Gengjin Yuan Shen, as well as the thick earth Yuan God that had been prepared for a long time, and successively accepted the suction of the Heavenly Tribulation.
