For several days, Mu Yu was thinking about what Wanwan said that day, and the dead wood didn't take another step out of the small courtyard, obviously being glued to Wanwan. After a few days of rest, Deadwood finally brought up the matter of the Stygian Grass.

"When separating the angry and dead qi of the Stygian Grass, you must be careful not to let the dead qi spread out, otherwise there will be unforeseen consequences. Feng Haochen said solemnly.

Evil Immortal often came over to join in the fun these days, he knew that Mu Yu planned to use the Stygian Grass to treat Feng Haochen's injuries, he surprisingly did not object, and said: "Don't worry about it so much, I'll help you cover it if something happens to the dead air, if it really doesn't work, I'll find a way to throw it to the sky." ”

"Don't forget the lesson of the First Heaven. "Feng Haochen is not the kind of person who does things without thinking about the consequences.

"One Heavy Heaven, what happened to One Heavy Heaven?" Mu Yu knew that having a triple heaven and a double heaven meant that there was a double heaven, and even a fourth heaven and a fifth heaven, but he had never heard of anything other than a double heaven and a triple heaven before.

"It's very simple, the first heaven was destroyed by the Stygian Grass. Evil Immortal said nonchalantly.

"What!" Mu Yu looked at the dark grass in his hand, startled, and almost threw it to the ground by mistake.

A heavy heaven was destroyed by this little grass?

Evil Immortal felt that Mu Yu was a little surprised, and said: "Where is this world as simple as you imagined? Since the birth of the world, everything is relative, and there are favorable factors for the development of the world, and there is also the existence of destroying the world, and the existence of the Stygian Grass is a proof of this. ”

After a pause, Evil Immortal continued: "Whether it is a heavy heaven, a double heaven, or a triple heaven, there is a dark grass. In the past, no one knew about the serious consequences of the dead qi produced by the Stygian Grass, so no one paid attention to it. Later, I don't know which guy from the One Heavy Heaven separated the dead air and the life of the Dark Grass, sucked the life, and then the dead air began to spread, and finally turned the One Heavy Heaven into a world without any living beings. ”

"Most likely, it was a good thing to do by a stupid guy like Yumon. Evil Immortal added.

According to what the evil immortal said, whether it is a heavy heaven or a second heaven and a third heaven, there are human races, demon races and demon races. One Heavy Heaven is mainly controlled by the Youmeng Demon Race, the human race and the demon race are almost extinct, in ten thousand years ago, a stupid Youmeng Demon Race found the only dark grass in the First Heavy Heaven, deprived the vitality away, and discarded the dead air.

At first, the amount of dead air is not large, and there will be no serious consequences. But the death gas is powerful in its contagion, it can gradually spread, turning everything it encounters into dead air, constantly expanding. After the Yumeng Demon Clan of the First Heavy Heaven found out that the situation was wrong, it was too late to save it, so they could only abscond to the Second Heaven and the Third Heaven one after another, and those who could not escape were eroded by the dead air, and the First Heavy Heaven was completely covered by the dead air.

Every heavy heaven has a dark grass, and Dead Wood said that he has been looking for a long time in the triple heaven and has not found it, so he can only let Mu Yu go to the second heaven to find it. Because he guessed that the Dark Grass of the Triple Palace was protected by the Triple Palace, it was impossible for Mu Yu to have the ability to take the Dark Grass from the hands of the Triple Palace.

The Stygian Grass is extremely terrifying, and it is not so easy to find even in the Double Heaven. What Mu Yu didn't know was that if the mysterious Phantom Qingyu secretly helped, he wouldn't have been able to get the Stygian Grass at all. Phantom Qingyu is the same as Sword Shadow Dust Wind and Evil Shadow Immortal, they are all immortal people with great cultivation, and he helped Mu Yu naturally to help Sword Shadow Dust Wind.

"Actually, I suspect that it should be the spirit lord of Yichongtian Mu Youmeng who sucked away the anger of the Stygian Grass at the beginning, Mu Youmeng's favorite is the vigorous vitality, and the anger of the Stygian Grass is a huge treasure for him, just think about his life and death ability in the blink of an eye. It's a pity that he was a fool and didn't deal with the dead air and ruined the whole world. "Evil Immortal gloated with schadenfreude on his face, it was the Yumeng Demon Clan who had the advantage in the first day, and their destruction really couldn't arouse the sympathy of Evil Immortal.

Mu Yu once used the ability of "life and death in the blink of an eye", his eyes represent life and death, and the fatal injury of Tian Ran and Feng Haochen was healed by his "life and death in the blink of an eye". It's a pity that this ability is too rebellious, far from being something he can control, and now that the Youmeng Spirit Lord in his body is sealed by the Nine Heavens Sealing Demon Array, Mu Yu can no longer use this ability.

The ability to defy the sky has more limitations, it is impossible for him to use his left eye to infinitely resurrect the Yumeng Demon Clan who died in battle, nor can he directly use his right eye to directly sweep away a large number of Terrans, this ability has a great load on his body, and the most important thing is that the Terran can resist that death qi to a certain extent.

At the beginning, Mu Yu seemed to be irresistible in the blink of an eye when he used life and death in the Moyun Mountain Range, but in fact, with his cultivation in the Jindan stage at that time, if he used it on people in the out-of-body stage, at most he would make the people in the out-of-body stage bleed a little nosebleed, and it would not cause any substantial damage at all, and even Mu Yu himself would be counterattacked.

"You don't have to worry about the excess anger of the Stygian Grass, the Heaven and Earth Formation will absorb it, and the solution of the dead qi is a big trouble. The passages to enter the One Heavy Heaven are all sealed, and it is unrealistic to throw them into the One Heavy Heaven, and you have to rely on the Wood Spirit that Mu Yu got from the Yumeng Demon Clan, but I don't dare to guarantee what will happen to the Wood Spirit after absorbing the death qi. Feng Haochen said slowly.

"Don't worry about those who don't, our Great Love Saint quickly resumes his cultivation Besides, I can't wait to beat up the defenders of the Triple Palace, that guy looks annoying from head to toe, there is no good thing in the Triple Palace!"

"Can you cover it up a little when you speak?" Feng Haochen was quite helpless.

Evil Immortal snorted disdainfully: "What are you afraid of? Are you still worried that the defenders will not be able to eavesdrop? Didn't you set up so many formations for this small courtyard? He has attained extraordinary achievements in the formation path, will the three of us lose to him?"

Although the evil immortal shouted every day that he wanted to kill Sword Shadow Dust, but Sword Shadow Dustwind was his old friend for thousands of years, and he couldn't really do it. The most important thing is that some of the practices of the Mie Palace are too much, and even he can't stand it.

"Alright, don't talk about it!, let's get to the Stygian Grass!" said Deadwood.

Everyone focused on the Stygian Grass in Mu Yu's hand.

The Stygian Grass originally needed an alchemist to be able to separate it accurately, but with Mu Yu here, he wasn't so worried. Although his alchemy technique was at the level of a three-legged cat, his control over plants was unmatched by others, not to mention that there was a dead wood by his side to guide him.

The consequences that the Stygian Grass can cause are also in the form of plants, it has a black and white leaves intertwined with each other, and the anger and death are maintained in a wonderful equilibrium state, which is difficult to break, just like the balance of the five elements in the ethereal land, the balance of life and death of the Stygian Grass is even more than that!

"You follow what I said, first separate the Nine Qi Soul Cleansing Flower. ”

Under the guidance of Deadwood, he first separated the dead qi of the Nine Qi Soul Cleansing Flower. The process of processing the Nine Qi Soul Cleansing Flower is not that complicated, because it is different from the Stygian Grass, there are not so many restrictions, and there is no internal balance problem, this process is easy for Mu Yu.

It is not so easy to separate the vitality and death of the Stygian Grass, and if the balance it maintains can be easily broken, the world will be finished a long time ago. The vitality and death of the Stygian Grass are involved with each other, and it is difficult for the power to restrain each other to be dispersed, and Rao is the ability to control the wood with Mu Yu is also extremely difficult.

"Be careful, try to find the point in the balance of the grass. Just by destroying that one point, you can separate the two leaves. Deadwood said.

Mu Yu's hand touched the Stygian Grass, and his entire consciousness had merged into the Stygian Grass. The two leaves of the Stygian Grass, the white contains infinite vitality, and the black is cold and domineering, the moment Mu Yu's consciousness entered the Stygian Grass, he felt like he was struggling on the edge of death and vitality, and he suddenly felt an unwarranted tremor in the depths of his heart, Mu Yu was shocked to find that there was something else in the Stygian Grass!

The two leaves of the Stygian Grass formed a world of their own, and he obviously entered from the junction of the two leaves, but he didn't grasp the degree well, and he still entered the dead air of the Stygian Grass. Surrounded by a vast black fog, whether it was under your feet, overhead, or around, the endless black fog could not be seen at a glance. The black mist was restless, condensing into various strange shapes from time to time, shaking faintly, drifting apart, and condensing again.

The pure black mist gives people a desperate impulse, killing, manic, restless, sad, all kinds of emotions rush up, making Mu Yu think of death for a moment! This is a primitive force, deducing all kinds of possibilities that can produce death.

This black mist is the so-called death qi, luring Mu Yu back to the embrace of death.

The black mist transformed, and suddenly the sky was bloody, all the black mist turned scarlet, and endless killing flashed in Mu Yu's eyes.

Then, Mu Yu saw a bloody scene!

The setting sun stained half of the sky red, and the blood-colored light poured down on the earth, illuminating the mess.

The ground was no longer so flat, and sharp earth pierced the ground, piercing corpses one by one, the blood still dry, the sword still in hand, but life was gone.

The trees lay horizontally, and the hard branches hung with human figures, and the leaves were blood-red, which was very strange.

The river had been frozen, and ice edges rose from the surface of the water, piercing through countless cultivators, and warm blood flowed down the ice edges, failing to melt the biting cold.

The flames burned on the earth, so vigorous, with the body of the cultivator as the source of fire, burning, burning, and reflecting the setting sun.

The cruel flying sword betrayed its master, the tip of the sword slashed through the heart, flashing cold light, and came out through the body, and the person holding the sword still had horror in his eyes, and he did not understand why the sword in his hand turned to him.

The tragic war between the Terran and the Yumeng Demon Race actually broke into Mu Yu's brain, and he saw all kinds of shocking deaths of the Terran cultivators, with their heads flying, their bodies amputated, their limbs broken, their bodies shattered, and their blood flowing like rivers! He saw that the Yumeng Demon Race turned into steam, into charcoal, into dust, into sawdust, into molten iron!

There is no chance of survival, there is no fluctuation of vitality, everything is death, everything is dying, and death is the final destination of all things. Here, there is no hope, no life is seen, and here, everything is showing the gesture of death!

Mu Yu hates this feeling, in the black leaves of the Stygian Grass is a world of death, staying for a long time will make people feel hopeless, and it will also make Mu Yu's consciousness dissipate itself and turn into death. He ran back, he knew where the breath of life was, and that direction was guiding him like a light in the dead silence. But he saw that the light was close at hand, but he couldn't reach it, and he galloped in the direction of his life, he wanted to get out of here, but he couldn't find an exit. Time was slowly passing, he felt that thousands of years had passed, but he still couldn't get to the intersection of life, and a breathtaking despair shrouded him from the bottom of his heart......

"Wow!"

As if he had been fished out of the water, Mu Yu's whole body was soaked in cold sweat. Deadwood's hand clicked on Mu Yu's, dragging his consciousness out of the dead aura of the Dark Grass!

"My consciousness is trapped in the world of the death of the Stygian Grass, and that place is terrifying. It took a long time for Mu Yu to spit out these words in horror.

"You enter in less than ten breaths. Deadwood said softly.
