The clouds are gloomy and bleak, and they are slaughtered.

The entire Netherworld is shrouded in the clouds of war, and there are six black holes in time and space, distributed all over the Netherworld, and the battle between the six demon kings and the Six Heavenly Palaces of the Netherworld is in full swing, and tens of thousands of ghost cultivators and demons are killed every day!

The big war has not started, the small battles are continuous, and neither side has sent out masters above the immortal level in the trial stage, after all, even if it is the entire netherworld, the real masters above the immortal level are only nearly a hundred, and the demon world is also about the same, the time for the decisive battle has not yet come, and neither side is willing to lose the immortal-level combat power.

In this kind of desperate fight between the monks of the two realms, several years have passed in the lower realm again, and the war between the two sides has begun to escalate gradually, and today the demon world hides immortal-level demon immortals in the army, killing tens of thousands of ghost cultivators in one fell swoop in the chaotic battle, provoking the fire of the Xudu Immortal Zun, and tomorrow will do the same, send his subordinate ghosts and immortals to join the battle, and also sweep away a demon!

You come and go on both sides, and no one will suffer!

However, in the Black Flag Battalion, Zhou Yu has completed the training of the Black Flag Battalion and is ready to lead the army to the lower realm!

Compared with a few years ago, the Black Flag Battalion is like two teams, waving the flag, the ghost spirit is condensed but not dispersed, and it is already an out-and-out elite division, and under the guidance of Zhou Yu, the strength of the seven commanders has increased to varying degrees, and almost all of them have become the strongest in the quasi-ghost fairy realm, and compared with the ghost in the original empty realm war, the overall strength is not much stronger than before.

In the Xuanxuan Palace, Zhou Yu saw the lord of the Yin Heavenly Palace again, still hazy, unable to see his face clearly, regardless of men and women, difficult to distinguish between old and young, quietly standing on the top of the mountain in the study micro-world, standing with his hands in his hands, indescribably chic and calm.

"I've seen the palace master!" Zhou Yu bowed, "The Black Flag Army has completed its formation, and it can participate in the battle in the lower realm at any time, and I also ask the palace master for permission to be in the lower realm." ”

The Lord of the Yin Heavenly Palace didn't reply, and said lightly: "Go when you're ready, you don't need to ask me! But one thing to remember, you can only stay in the battlefield of the Netherworld Thirty-one City, and you must not move to the battlefields of the other five heavenly palaces!"

Zhou Yu was stunned for a moment, why is this? Puzzled in his heart, Zhou Yu didn't ask more, nodded, and turned to leave......

In the perception of the Yin Heavenly Palace Lord, Zhou Yu led the army to leave Nai He Tian, all the way towards the battlefield of the Netherworld Thirty-One City, and sighed, in the past few years, as he continued to consume mana to deduce the heavenly machine, he gradually understood many things. This Netherworld Catastrophe is a matter of days, but it is also a man-made calculation.

The Six Heavenly Palaces have been in charge of the Netherworld for too long, and he, as the master of the Yin Heavenly Palace, has been in the first place in the Six Heavenly Palaces for too long.

Counting the Demon Realm and the Netherworld, ten of the twelve Great Holy Masters are actually in the midst of calculations! Now, although the Yin Heavenly Palace Lord understands the cause and effect, he can't change the development of the Great Tribulation, and he doesn't want to change it!

The Yin Heaven Palace Lord knew that Zhou Yu was his own reincarnation, and it was impossible for his reincarnated body to come to the Netherworld before the endless years, and to see his own, he saw another self, which was a paradox in itself!

And the Yin Heaven Palace Lord himself also understood why the one behind the scenes would send the reincarnation here, and also asked him to kill himself, it seemed impossible, but in fact, it was precisely the hope that he would never kill himself in the future life!

It's very contradictory to say, but the Yin Heaven Palace Lord understands that after reaching a higher level, a strong person can achieve all kinds of unbelievable things, and even say it wrong, turn wrong into right, and all kinds of impossibilities can become facts!

It's like if after this calamity, if the reincarnation kills oneself, and oneself is reincarnated as him, this is an irrationality in itself, but it exists.

If you reach the legendary Dao Fruit realm, you can even go back to the beginning of everything, the beginning of the beginning, and leave your own figure in all the later times, changing the cause and affecting the consequences. For example, the Yin Heaven Palace Lord fell in this catastrophe, but if a Dao Fruit realm powerhouse made a move, he could go back in time to before the fall after the fall, so as to reverse the ending.

It's incredible, it's immeasurable.

Obviously, the person behind the scenes has not reached the realm of Dao Fruit, otherwise there would be no need to be so troublesome, or in fact, he was not in his heyday, he was subject to any restrictions, so it was difficult to directly change the catastrophe, in other words, he did not have the ability to kill himself at this time, otherwise he would not have borrowed Zhou Yu's hand, and in the later generations, it was difficult for him to wake up at the current node for some reason, so he made this decision!

This is the opportunity, the opportunity to give the Yin Heaven Palace Master, more precisely, the opportunity to Zhou Yu! The Yin Heaven Palace Lord planted the seed in the magic passed on to Zhou Yu, once the time comes, he will understand the cause and effect, this is the back move of the Yin Heaven Palace Master, do not interfere much, take care of but not preach, everything looks like normal.

Zhou Yu naturally didn't know that there were so many calculations and countercalculations behind this, he only knew that this Netherworld Tribulation was not only the Heavenly Palace, once he missed, it would inevitably be the end of the catastrophe, but he didn't know that the Lord of the Yin Heavenly Palace had now seen through everything and laid a follow-up.

Led the Black Flag Army to the Nether Netherworld Thirty-one City, the black clouds of the void with a radius of hundreds of thousands of miles were like ink, and countless ghost armies were in the clouds, and above the clouds, a black hole the size of a hundred miles was slowly rotating, like a dark whirlpool, in which there were countless ghost roars and demon roars, and the fight was in full swing!

Even if Zhou Yu has seen a lot of big scenes so far, but such a scale of the war still shocked Zhou Yu, in comparison, the 100,000 Black Flag Army behind him is so small, in this kind of catastrophe, it is really like ants below the immortal road, people and immortals are everywhere, there are many immortals like dogs, and the heavenly immortals and the holy lord level are the backbone and top combat power of the catastrophe!

Even the blood station in front of him can only be regarded as an appetizer, when the empty black hole is completely opened, when the armies of the two realms are overwhelmingly rushing to kill, the blood flow is not enough to describe, no wonder the Netherworld in the future will be so bleak!

And when there is a big battle between the Heavenly Immortal Level and the Holy Lord Level, I am afraid that every move will cause a big shock in the two realms, and that is when the catastrophe is at its peak, the Heavenly Palace is broken, but the sky is shattered by the aftermath and falls to the lower realm......

Just thinking about it, Zhou Yu unconsciously became nervous, to this day, what he wants is to live, to live to the post-catastrophe, and to live to return to the afterlife!
