This was the most intense life-and-death crisis in Bai Xiaochun's life. He had no way to stop it and had no strength to struggle. Everything seemed to be a foregone conclusion after the Tianzun took action to force him to merge with Du Lingfei.

His cultivation in this life will eventually turn into a peerless pill that will allow the Heavenly Lord to transcend from then on, together with Du Lingfei, under the formation of the alchemy furnace.

Bai Xiaochun never thought about this ending before that, even though the poor ancestor had said meaningfully that sooner or later, he would turn against the Heavenly Lord.

But Bai Xiaochun still naively believed that with Du Lingfei, he had no deep hatred with Tianzun, and behind him was the tomb guardian and his disciple Bai Hao. There were too many trump cards that gave Bai Xiaochun a certain degree of confidence.

But... all of this is just a mirror...

His consciousness has long been blurred. The difference is that the aura from Du Lingfei made the two of them feel sober in this fusion.

"Maybe all this is also the plot of the tomb guardian......" Bai Xiaochun murmured, and his consciousness blurred again.

Almost as Bai Xiaochun realized that the tomb guardian had made some kind of push in his life and death crisis, in the wilderness, deep in the land of Kuihuang City, in the ruins of the lower three cities, and on the broken tower, the tomb guardian sitting cross-legged there opened his turbid eyes.

"Bai Xiaochun, I hope you... don't hate me. This is my mission of existence... and also the mission of the Emperor of the Underworld." The guardian of the tomb was bitter and whispered softly, he slowly raised his head and looked at the Void.

At the end of the wild and empty space, there is a big river that outsiders cannot see. The river water is pitch black and flows continuously. In contrast to the vitality represented by the sea of ​​heaven, this river represents... death.

There are countless unjust souls flowing in the river. These souls roar in struggle, but they cannot leave the river. They can only go away with the river and enter the cycle of reincarnation...

This river is called the Styx.

At the end of this nothingness, the source of the Styx River... On the majestic river water that looks like sea water, there is a pitch-black palace. This palace exudes the meaning of death, and there is no light in the cold.

This is...the palace of the underworld!

In the Nether Palace, this generation of Emperor Bai Hao sat there silently. He was wearing an imperial robe, and his whole body emitted a strong breath of death.

But his face was no longer as majestic as usual, but full of anxiety. The intensity of this anxiety seemed to have affected the Palace of the Underworld and the River Styx, causing the sound of big waves to be heard from time to time.

Bai Hao's eyes were full of worries. He had seen the failure of the great subordinates of the Heavenly Lord and the tomb guardians with his own eyes. He was also taking action and was collapsed by the Heavenly Lord.

Although Bai Hao didn't know all about the purpose of taking Bai Xiaochun away, he could have some guesses. He knew that the master must be in great crisis at this moment!

He understood that looking at the whole world, now... the only one who can save his master is himself!

He knew the weakness of the tomb guardian, and he knew that the current tomb guardian would return to the ruins at any time and was no longer as strong as before. He even understood that even if he was the Emperor of the Underworld, he would definitely not be the opponent of the Heavenly Lord...

"Master..." Bai Hao whispered in a stern voice, and scenes appeared in his mind. With Master, all kinds of things constantly appeared in front of him.

That was his only relative, that was the person he thanked the most in his life, that was the person he Bai Hao once vowed to protect with his life...

That was also... the happiest time of his life.

Gradually, the picture in his mind disappeared, and in the end there was only one picture left... that picture that was deeply imprinted in his soul and could never be erased in his life.

In the picture, Bai Xiaochun turned his back to him and spoke lightly, telling him that from then on, he would accept him as a disciple...

"Master..." Bai Hao smiled this time, with decisiveness, determination, and a strong sense of determination in his smile!

He understood that if he wanted to rescue Master from Tongtian Island in front of Tianzun... there was only one way to do it!

That is...the twenty-two colored fire that has refined the limits of this world!

Before this, even though Bai Xiaochun was already a god, Bai Hao still did not stop deducing the formula of the twenty-two-color fire. Until finally, he had realized through this deduction that the limit of this world was the twenty-one-color fire.

Unless in special circumstances, it is impossible to appear twenty-two-colored fire, because after the twenty-two-colored fire exceeds the limit of the world, all the multi-colored fires under it can be regarded as ordinary fire, and the twenty-two colors are already immortal fire!

Once the twenty-two-colored fire appears, it will immediately become the unparalleled strongest force in this world. The twenty-two-colored fire can burn all existences in the world.

And such fire is enough to fight against the Heavenly Lord, giving Bai Hao the possibility of saving Bai Xiaochun in front of the Heavenly Lord!

But... if you want to refine the twenty-two-colored fire, there is no soul in this world, and it can be used for refining fire. Even if you use all the souls in the Styx to refine it, you will eventually stop at the twenty-one color.

"There is only one way..." Bai Hao looked stern and murmured, his eyes were extremely firm and strong, and he was extremely decisive!

This method is to refer to the fire refining method of the Miao Liner family, use the soul of the Emperor of the Underworld as the main material, burn yourself and refine your own soul... Only then can you refine the unique... twenty-two colored fire in this world!

Only this method can be done!

After all, he is the Emperor of the Underworld, a god-like existence who controls the River Styx and controls the cycle of reincarnation in this world!

"Master... I'll save you..." Bai Hao smiled, smiling, his tears flowed down, but his absolute certainty did not decrease at all.

Even if this method is so expensive that he can't bear it, he still... has no regrets!

Even if this method will make Bai Hao... all the aura of existence be erased from now on, he will still... be without complaints!

Because that was his master. The moment he knelt down to Bai Xiaochun, he had already decided... the teacher's kindness is as good as the sky!

His tears were not the essence. At the moment they were flowing, they became part of the Styx River. Bai Hao took a deep breath, stood up slowly, raised his right hand suddenly and waved it violently.

"Here is the soul!"

Suddenly, outside the Nether Palace, the endless unjust souls from the Styx suddenly came from all directions. After penetrating the Nether Palace, they surrounded Bai Hao's side, and gradually formed a huge vortex.

As the vortex rumbling turned, Bai Hao made a gesture with his left hand and suddenly pointed to his eyebrows. As his fingertips fell, his body seemed to burn, and flames suddenly arose from his body!

This is a color of fire...

It was not over. As Bai Hao's hands quickly pinched the soul sea around him, the surroundings rotated faster. Widths of soul flew out and merged into Bai Hao's body, causing the flames on his body to increase continuously at an astonishing speed.

Two-color fire, three-color fire, four-color fire...

In just a few breaths, the sea of ​​fire on Bai Hao's body became more and more majestic, and its color had become sixteen colors!

Still continuing!

If there is a person in this world who can go alongside Bai Xiaochun in fire refining, or even slightly surpass it... then this person can only be... Bai Xiaochun's disciple, the contemporary emperor of the underworld... Bai Hao!

With the roar, Bai Hao's body burned more and more, and countless souls came wildly in the soul sea around him, until the flames on Bai Hao's body became seventeen colors, eighteen colors and even nineteen colors...

There is no end!

Bai Hao's eyes became more and more determined. With a wave of his hands, all the souls around him shook at this moment. After all, a loud noise suddenly echoed at the source of the River Styx where the entire Nether Palace was located.

Twenty colors!

Twenty-one colors!

Until this moment, Bai Hao raised his head and let out his strongest roar and roar towards Xuwu!

In this roar, his soul... suddenly burned, with the help of this burning power, with the help of his own soul of the Emperor of the Underworld, with the River of Styx as the root and the soul as the basis, Bai Hao's eyes were also filled with flames. The twenty-one colored fire burning on his body at this moment... gradually... another color appeared!

It is... Twenty-two colored fire!!

At the moment when these twenty-two-colored fires appeared, the entire wild world seemed to have no change, as if everything was as usual, but all the monks on both sides fighting on the battlefield trembled for no reason, as if there was a breath they could not see but made their souls tremble suddenly descended in this world!

Whether it is the Nascent Soul, the Heavenly Man, or even the Demigod... they were all shocked at this moment and inhaled in horror!

Not only the wilderness, but also all the creatures on the Tongtian Continent, whether they are monks or ferocious beasts, even vegetation or mortals, all of them are all, and there is a wide range in the sky of the entire world, covering all the sky like never before... the world net!!

Impressively, at this moment, all the existences in the whole world seemed to be in my ears, and I heard the murmurings echoing in the heaven and earth under the unimaginable pressure!

"Master...I'll save you!"
