Pushing open the dusty door, a warm and humid breath came to my face.

A vast underground world with green waters and green mountains but buried bones came into Su You's eyes.

Looking around, I saw that the pavilions and pavilions were scattered, and the imprints of golden flames were carved on both high walls and low buildings.

The dust that accumulates on the surface is a testament to the antiquity of this underground world.

"As you can see, these corpses that have been sealed in this land forever are the Holy Fire Race of the past."

Jiang Nu'er took Su You's hand, walked past those corpses, shook his head and sighed, and said, "They all died because of the outbreak of cold poison in my body... Not even a single remnant soul remained. ”

"Miss Jiang..."

"Don't worry, I'm fine." Jiang Nu'er turned her head and smiled at Su You, then stretched out her hand and pointed to the center of this land and said, "Do you see that Flame Tower?" That's where I'm going to take you, and maybe we can find some good stuff there too. ”

With that, he took Su You and walked straight towards the tall tower not far away.

Approach the Tower.

An even more intense fiery aura emanated from it in all directions.

Jiang Nu'er stepped forward and slowly pushed open the dusty tower gate, and then led Su You up the stairs in the tower all the way up until he reached the top of the flame tower.

At the top of the tower was a shattered statue of a fire lotus, and above it was a faint golden flame flickering and burning.

It seems that he sensed the existence of the same kind in Su You's body.

The golden flames that emitted a faint light turned into golden spiritual power and wrapped around Su You's body, slowly merging into the true fire of the sun in the heart of the Chaos Dao.

And at the moment when the golden flame actively integrated into Su You's body, the original warm and humid world of green mountains and green waters suddenly blew a fierce cold wind from nowhere.

The cold wind passed through and there was not a single grass left.

Only a gust of wind was heard, and everything around it that was originally full of life was frozen into ice sculptures, and then turned into dust in the gust of cold wind and was blown into the air and gradually dissipated.

However, in the blink of an eye, only the flame tower where Su You and Jiang Nu'er were located was still standing in the huge underground space.

"This cold wind... Is it a cold poison? Seeing the sudden change in the vision in front of him, Su You turned his head to look at Jiang Nu'er, whose face was a little pale, and stretched out his hand to pull him closer.

The Yang Zhigang of the Sun True Fire made Jiang Nu'er feel a little better, and she hugged Su You's hand and said in a deep voice: "Since I was born, I was found to have awakened the Heavenly Cold Poison Body, and the elders in the clan used the power of the Sun True Fire to suppress all the cold and poisonous breath that erupted in my body in this land, so that one day I can use this method to exhaust all the cold and poisonous breath in my body and let my body return to normal." ”

"However, everyone in the clan underestimated the power of the cold poisonous aura, as the cold poisonous aura continued to erode their bodies, even the origin of the true fire of the sun was suppressed, and they could only seal the cold poisonous aura under the Burning Sky Holy Altar, but they could not completely remove it."

"Now that the true fire of the sun has been absorbed and refined by you, these cold and poisonous breaths will no longer be suppressed, and they will naturally surge like a tide."

"Cold poison is like a deadly poison to me, but to you it can be a treasure gifted by heaven and earth."

"Treasures?" Su You was surprised and asked, "Do you want me to absorb and refine these cold poisonous breaths?" ”

Jiang Nu'er nodded and responded: "The spiritual power in a cultivator's body is usually in a state of yin and yang balance, once the yin and yang are out of balance, it will lead to all kinds of unexpected situations, and it is possible for the cultivation realm to regress or even die on the spot. ”

"But even if it is the cold poisonous aura that represents the extreme yin, it is also a kind of spiritual power, as long as you find something that can balance this power, you can absorb and refine it, which is not only harmless to the human body, but also can increase the cultivation realm."

"It can be said that the cold poisonous breath is exactly what you need to break through to the sevenfold consummation of the Innate Realm at the moment, and it is also the easiest to obtain."

After listening to what Jiang Nu'er said, Su You sat cross-legged at the top of the Flame Tower, and began to operate the Yin and Yang Open Heaven Record in his body to attract the cold poisonous aura that had spread throughout the ground.

An extremely strong suction force pulled the cold and poisonous breath that was blocked by the breath of the sun's true fire outside the flame tower.

It was like finding an outlet for anger, and the cold poisonous aura poured into Su You's body like a tide.

Su You immediately released the fiery power of the sun's true fire and began to balance the cold and poisonous aura that represented the power of extreme yin.

Even the remnants of the fifty percent cold poisonous aura in Jiang Nu'er's dantian were also pulled at this time, constantly overflowing from his body, surging towards Su You's body.

Chaos Dao Heart.

The origin of the sun's true fire continued to burst out of Dao golden spiritual power, enveloping and cutting the extremely cold poisonous aura, devouring and refining.

Gradually, beside the golden flame that represented the true fire of the sun, a miserable white and deep flame that constantly emitted cold air condensed and took shape.

"This... This is Taiyin real fire! ”

Jiang Nu'er, who was standing beside Su You and noticed all this, opened his eyes wide, revealing a look of disbelief, he didn't expect that the cold poisonous aura would condense in Su You's body and become the Taiyin True Fire, which was also one of the origins of the Divine Fire.

The Taiyin True Fire that emitted bursts of white light was Yin to the softest, although it was a flame, it was extremely cold, and it only took a wisp to freeze the heavens and the earth, and its flame could directly harm the cultivator's soul and spirit, and the power was not under the Sun True Fire.

Meanwhile.

Su You, who had condensed the Taiyin True Fire, suddenly opened his eyes, and the golden flame representing the true fire of the sun and the white flame representing the true fire of Taiyin were condensed in the pupils of the left and right eyes.

Although it was fleeting, two flames shot out, instantly dispersing the cold poisonous aura that remained around.

The spiritual power aura in the body also climbed to the extreme at this time.

"Poof!"

The barriers between the realms were instantly broken through by this spiritual power.

Su You's cultivation realm finally came from the sixfold heaven of the innate realm to the sevenfold consummation.

But it's not over yet.

At this time, Su You, who closed his eyes and concentrated again, guided the two extreme yin and yang forces into the dantian.

He wanted to try to break through to the Yuan Dan realm in one fell swoop.

So he condensed the true fire of the sun and the true fire of the Taiyin, as well as the spiritual power of the whole body, and wanted to condense his own Yuan Dan in the dantian.

However, there are gains and losses.

Yin Yang Open Heaven Record gave Su You the ability to break through the realm by absorbing and refining the qi, blood and spiritual power of others, but it also made Su You always require far more spiritual power than a monk of the same realm every time he broke through.

The spiritual power required for Su You to break through the Yuan Dan Realm was also several times that of a cultivator of the same realm.

So until the spiritual power was exhausted, the Yuan Dan in the dantian had just condensed a vague outline, and had not yet become a real Yuan Dan.

did not force himself to break through the Yuan Dan realm, and when his spiritual power was exhausted, Su You opened his eyes and restrained his breath.

"Your growth rate is really fast, and you are the most talented person I have ever seen."

Reaching out to feed Su You an elixir to restore spiritual power, Jiang Nu'er smiled and said, "Now you have not only obtained the origin of the true fire of the sun, but also condensed the true fire of Taiyin, but this space without the support of spiritual power will collapse in a short period of time, so let's hurry up and leave here first." ”

As soon as the words fell.

A slight shock proved the correctness of what Jiang Nu'er said.

The two of them stopped and jumped straight down the flame tower before rushing towards the passage.

And the moment the two of them left, the flame tower, which had lost the support of the sun's true fire power, immediately fell apart, and the huge stones smashed on the ground with a loud bang.

Soon.

When the passage behind him kept collapsing, and even the part of the Burning Heaven Altar on the ground began to collapse, Su You and Jiang Nu'er successfully ran out of it.

"Finally... Is it over? ”

Turning to look at the Burning Heaven Altar, which had become a ruin, a trace of sentimentality flashed in Jiang Nu'er's eyes, and she immediately became firm again.

Returning to Su You's side, he asked softly, "Little guy, do you have any plans next?" ”

"I'm going to go to Tianhua City to attend the alchemy conference in three months."

Su You was already accustomed to Jiang Nu'er holding his hand, and he pretended to tease and reached out to scratch the other party's nose, and asked with a chuckle, "What about you?" Are you planning to go back to Tiandu Auction House? ”

"What? Does the little guy want to give up? ”

Jiang Nu'er stretched out her hand and gently grabbed Su You's ear, exhaling hot air and slowly saying in her ear: "I won't go back to the auctioneer of the auction house on the same day, if you don't dislike it, little guy, I can stay by your side as a protector, and I will go wherever you go." ”

"What's more, the cold poison in my sister's body hasn't been completely cleared yet, can you bear to watch my sister be eroded by the cold poison and die?"

"Alright, alright! Can't I say yes..."

Being entangled by Jiang Nu'er, Su You, who was really a little afraid, had no choice but to agree to Jiang Nu'er's proposal to stay by his side as a protector.

The requirement is that Jiang Nuer can't show up at will, and she is not allowed to tease him at will.

Jiang Nu'er happily accepted, dropped a kiss on Su You's face, and said with a smile: "Then let's go back to Tai'an City as soon as possible to pack our luggage and prepare to leave, it just so happens that I also want to go to the alchemy conference to see the excitement." ”

Immediately, the two of them lifted their feet and left Wohu Mountain.

After returning to Tai'an City, they packed their luggage and dealt with everything, and rushed to Tianhua City while practicing according to Su You's plan.
