(Ahem, who said earlier that it was a full moon night in early May?) Is it Kun Kun? Definitely not, Kun Kun has been in the first grade! Well, it's the waning moon... ）

The big slave stayed on the barren slope with Lao Dao, without the two refining corpses, there was no need to worry about the threat, and the residual breath of the two refining corpses was enough to make those poisonous insects dare not take a step beyond the thunder pool, so Mu Yi was not worried about them too much.

When he was close to the battlefield, the aura on Mu Yi's body had already converged, although he was still standing there, he couldn't feel any breath, if he didn't look at it with his eyes, it would be as if Mu Yi didn't exist.

At the beginning, Mu Yi also got two jade boxes from the tomb of the king, one of the jade boxes stored a broken volume of the Six Heavens True Formula, in which only the invisible body talisman and the soul travel three realms talisman were complete, so for a long time, Mu Yi has also been slowly studying.

It's just that these two kinds of talismans are really profound, even with Mu Yi's current realm of the way of talismans, he can only know a little bit about it, and if he wants to fully grasp it, I'm afraid he can only wait until he really reaches the third level, or even the fourth level.

Although he can't master it, Mu Yi also learned something from it, especially the invisible body talisman, which is not only a talisman, but also a rule, Mu Yi ingests the rune from it, although he can't do the real invisible body, without leaking a single breath, but he can barely restrain his breath, and his vitality is all restrained, like rotten wood, which is also the main reason why he dares to enter the battlefield.

Because as long as those resentful spirits don't feel angry, they won't attack him, and it is said that the real use of this invisible body talisman is to cover the heavens, it is said that as long as you wear this talisman, even the heavens and the earth cannot be found, and no hexagram can count him, which is really terrifying.

Li Cripple looked at Mu Yi's changes, his eyes flashed a few times, but he didn't say anything, and then he also cast a secret technique, and the breath of a living person suddenly dissipated, replaced by a thick dead air, so as to hide the vitality of his body.

Although this method is harmful to the body, it is also a method, and after refining corpses for so many years, there must be a set of its own methods.

In front of the eyes of the two of them, it is a desolate place, especially in this big mountain, it is also a miracle to have such a place, at least for several miles, look at the remaining traces, there should have been trees here back then, but after more than 300 years, only a dead silence and desolation have been left.

The arrival of Mu Yi and Li Cripple did not cause any movement, but then, Mu Yi also saw a shadow floating in the distance, that shadow could only be regarded as humanoid, without any sanity, just passing over this dead and silent land, aimlessly.

The two entered this dead and silent place, although hundreds of years have passed, they still see some similar dry bones from time to time, but most of them have long been weathered and changed, which is also because of the strong yin qi in this place, otherwise the truth would have been lost.

A gray cloud floated in front of the two of them, and the two of them remained motionless at this time, waiting for the gray cloud to drift away before they breathed a sigh of relief, the gray cloud itself was not terrible, but there were many shadows inside, like a team of soldiers and horses passing by.

Subsequently, Mu Yi saw some headless phantoms, saw some formless shadows, these resentful spirits can be described as strangely shaped, the only thing they have in common is that they have no intelligence, and they all rely on instinct.

"Master, the Nether Flower is ahead." Li Cripple gestured to Mu Yi, in front, there was a valley, a hollow place, which was also the place where the Nether Flower grew.

The two of them had a smooth journey, and there was no accident at all, which couldn't help but make Mu Yi have some contempt for the ancient battlefield, especially the souls of the fallen soldiers on this battlefield were swallowed by the Holy Spirit, and without the soul, ghosts would not be formed, just some resentful spirits, but they were not terrible, at least the strongest resentful spirit that Mu Yi encountered had just reached the second difficult level.

If you don't worry about startling the grass and snakes, Mu Yi can kill it with your hands.

The two of them soon came to the small valley, where the yin qi was even stronger, especially at night, almost wanting to turn into substance, and the place that Li Cripple was pointing to was in the middle of this valley, where Mu Yi vaguely saw countless corpses lying horizontally.

"Hey, how are the bones here similar to when they first died?" Entering the valley, Mu Yi soon discovered a strange place, he didn't feel anything from a distance before, but now, he clearly saw that these corpses that had been dead for hundreds of years, except for the lack of flesh and blood, the bones looked crystal white, and they looked no different from just dead.

Mu Yi felt it carefully for a while, and found out the reason, these corpses and bones, a large amount of yin qi has been accumulated, and it is precisely under the nourishment of these yin qi that these corpses are as new as new, fortunately, the soul of this army was devoured at the beginning, otherwise it would really become a fierce place, even more terrifying than the mass grave outside Cangzhou City, even if a ghost king appeared, Mu Yi would not be surprised.

This is also the reason why after every great war in the past dynasties, there are always monks on the battlefield who carry out excess, in order not to let the soul stay in the yang world, otherwise under the nourishment of that huge yin qi, it is inevitable that countless powerful ghosts and fierce ghosts will be formed, which will bring disaster to the world.

But like the battlefield in front of you, no one cleans and buries it, even if there are no ghosts, but over time, countless resentful spirits have been formed.

In the end, under the finger of Li Cripple, Mu Yi found the so-called Netherworld Flower, but at this time, the Netherworld Flower was wrapped in endless Yin Qi, and the Yin Qi was so thick that it almost turned into substance, and more importantly, around it, there were several powerful resentful spirits wandering.

These three resentful spirits can be said to be the most powerful resentful spirits on this battlefield, although they don't know how strong they are before they make a move, but they can make Mu Yi faintly feel a sense of threat, and this alone proves that the three resentful spirits are difficult to entangle.

And when Mu Yi and Li Cripple arrived, the three resentful spirits also glanced at the two of them, as if to warn.

"Master, this resentful spirit seems to have increased by one, according to the records of my master, there were originally only two powerful resentful spirits here, but now it has become three." Li Cripple said to Mu Yi, in fact, after entering this battlefield, the two of them have always been transmitting sounds, otherwise if they open their mouths, it is easy to leak their anger.

"Three doesn't matter, when the Nether Flower opens, I will first entangle these three resentful spirits, and then you take the opportunity to seize the Nether Flower and leave here." Mu Yi also said that if he didn't make a move, even if the three resentful spirits in front of him only faintly felt that he was a threat and regarded him as a competitor, but once he did, he would not be able to hide his vitality, and he would definitely be attacked by a group at that time, at that time, there would be more than just three resentful spirits, I am afraid that there would be thousands of them, stirring up the entire battlefield.

And seeing those three resentful spirits guarding around the Nether Flower, it was obviously not until they absorbed the Nether Flower that it was very beneficial to them, and now it was just a confrontation.

The Netherworld Flower is still just a bud at the moment, black and purple, and it looks like the Netherflower is like a living thing, and when it breathes in, it will swallow the infinite yin qi around it and turn it into nutrients.

However, if this Netherworld Flower wants to really open, it can only be considered perfect with a little yang energy, so it will open when Yin and Yang meet.

Strictly speaking, the opening time of the Netherflower should be at the turn of the child and the ugly time, the so-called yin energy is extremely prosperous, and thus, a trace of yang between heaven and earth is generated, which is the so-called intersection of yin and yang.

The intersection of yin and yang here does not mean that until the sun rises, at that time, the yin energy has long receded, and the yin and yang converge, between life and death.

"Master, can I absorb the Nether Flower here?" Li Cripple asked suddenly.

"Here? Aren't you afraid of death? Mu Yi glanced at Li Cripple in surprise, and from the three resentful spirits in front of him, he could see that when this Netherworld Flower opened, it would inevitably attract countless resentful spirits, and even if he stopped the three Glyphant Spirits, it would be difficult to stop all the resentful spirits in the entire battlefield, so Li Cripple wanted to absorb the Netherflower here, purely to find death.

"Master, this Netherworld Flower was planted by my ancestors who refined the corpse, since I knew that this Netherworld Flower had a strong attraction to resentful spirits, so I naturally made preparations for a long time, in fact, below here, there is a formation, as long as you hide in that formation, you can safely absorb the Netherflower Flower, but that formation can only accommodate one person, so..." Li Cripple couldn't help but lower his voice at the end, although his words were not finished, but the meaning was already very clear, when the time came, let Mu Yi block all the resentful spirits for him, and he took the opportunity to activate the formation, and then hid inside to absorb the Nether Flower.

"Yes."

Unexpectedly, Mu Yi directly agreed, which made Li Cripple a little surprised, in fact, even if he left here, he could still absorb it, but in comparison, it was undoubtedly better to stay here, he was refining the corpse with the help of Yin Qi cultivation, according to his original plan, he brought the refining corpse in, so that the refining corpse could resist the resentful spirit, and he hid in the formation while absorbing the Nether Flower, and at the same time strengthening the refining corpse with the help of the Yin Qi here, it can be said to kill two birds with one stone.

But now, it is naturally impossible for the refining corpse to follow up, let alone evolve again, so Li Cripple can only absorb the Nether Flower by himself and strengthen himself as much as possible, so that he can survive the transformation of anger and become stronger.

Although it has been banned by Mu Yi, Li Cripple's ambition has not diminished at all, and his desire to become stronger has become more intense, and this desire cannot be suppressed even by Mu Yi.

"Thank you, master." Li Cripple was overjoyed, and this time his thanks were also sincere, after all, if Mu Yi hadn't blocked those resentful spirits for him, he wouldn't have had time to enter the formation at all, and it was still a question whether he could even capture the Nether Flower.

Of course, if Mu Yi didn't appear, he would also have the possibility of success by refining corpses.
