The black "Key of the Nine Shades" is simple and unpretentious, but at this moment, it is constantly blooming and gloomy, and with the voice of the Yin Netherworld, the "Key of the Nine Shadows" continues to grow, and in a short period of time, it has become several times the size of before.

Moreover, this growth trend has not slowed down, but is getting more and more violent, and the swarthy "Nine Shades Key" is no longer as small as before, very clumsy, and has begun to transform into large objects such as sledgehammers and mallets.

Lei Yu's brows furrowed slightly, the "Nine Shades Key" that could be held with one hand before now had to be held with two hands. He felt that he was not holding a key at all, but was lifting dozens of large mountains, which made him feel breathless.

"What's the matter, how can this 'Key to the Nine Shades' be so heavy?" Lei Yu cried out in his heart, this 'Key to the Nine Shades' was far from being as simple as it seemed, and this weight alone was enough to make him desperate.

"Senior, what the hell is this, why is it so heavy!" Lei Yu was a little impatient, the current "Nine Shades Key" is more than ten zhang long, and the black and slippery autumn is like a thick wood, and this wood is extremely heavy, I am afraid it is not comparable to Wan Jun.

With a "boom", Lei Yu threw away the "Key to the Nine Shadows" in his hand, he really couldn't support it anymore, his mouth was panting like a dog, and there was sweat on his forehead, almost becoming a river.

He was sure he had never seen anything so heavy that even he couldn't lift it. If a cultivator is accidentally hit by this thing, he will be sure to turn into meat puree immediately, and there is absolutely no second possibility.

His eyes looked at Yin Ming, and when he saw the playful smile on Yin Ming's face, he understood that he had been deceived, and Yin Ming had long known that Yin Ming was doing this, and he did it on purpose.

However, now he can only smile bitterly, who let this be his own choice, no wonder Yin.

"Stinky boy, this 'Key to the Nine Shadows' is the 'Nine Shadows Emperor' personally refined from the 'Starry Sky Divine Sand', although it is not a thunder soldier, but in terms of hardness, it is definitely much stronger than ordinary thunder soldiers. It's good that you kid has been able to hold on for such a long time, and it looks like you haven't relaxed during this time!"

Yin Yin said with a smile, stretched out his hand, and in an instant, the huge black wooden stick quickly shrank, until it was only the size of a finger before it was taken into Yin Yin's hand.

Lei Yu gasped, he had heard of the "Starry Sky Divine Sand", it was the supreme divine object in the starry sky, and every grain of the "Starry Sky Divine Sand" had the weight of progress, and this "Nine Shades Key" was refined from the "Starry Sky Divine Sand", and it was normal to have such a weight.

"Hey, that old guy is here so soon, it seems that I really can't wait!" Yin Ming muttered to himself, not caring about the "Key to the Nine Shadows", but looking at the sky, with some solemnity between his eyebrows.

"Senior, is there any enemy?" Lei Yu said carefully, Yin Ming is a strong man in the Immortal Thunder Period, but now he has shown such a look, which makes his heart beat for a while, and it is definitely not simple to be able to make Yin Yin and Yin so cautious.

"A very nasty person!" replied calmly, looking into the distance without turning his eyes away, as if there was something in that void that made him cautious.

A purple cloud suddenly emerged in the distant void, the clouds were layered on top of each other, with a trace of dignity, as if an emperor had descended into the world, and there was a coercion that belonged to the emperor in every gesture, directly pressing on Lei Yu's heart.

"Immortal Thunder Period, definitely Immortal Thunder Period!" Lei Yu's eyes widened, without blinking, he felt that the aura was somewhat familiar, as if he had seen it before.

"Old friend, I haven't seen you for a long time, is that how you welcome the old man?" Before anyone arrived, the sound came first, and a peaceful voice sounded from the purple cloud, and then I saw the purple cloud disperse, revealing the scene inside.

A middle-aged man in a purple robe stood in the void, his hands behind his back, and his instrument was lofty, placed in the void. All around him, the endless void began to tremble, twisting together as if in submission to him.

He stepped out with a hint of a smile on his face, as if he had crossed the limit of distance, and in an instant, he came to the front of Lei Yu and Yin Ming, the speed was so fast that Lei Yu didn't react, and could only watch the middle-aged man's original location.

"Zixiao Ancestor!" Lei Yu was shocked in his heart, and he saw the middle-aged man in front of him clearly. He always had a smile on his face, and when he opened his eyes, there seemed to be the sun, moon and stars disillusioned inside, like a deep pool, and if you looked at it, you would fall into it.

Involuntarily, Lei Yu took a few steps back, the coercion of the Immortal Thunder Period made it difficult for him to hold himself, and it seemed that he might be crushed into pieces by this coercion at any time, but soon, another gentle breath blew in, like a spring breeze, sweeping away the sense of oppression brought by Zixiao Ancestor.

"Boy, you are now the sect master of the Hell Demon Sect, not a disciple of the Zixiao Sect, you represent the Hell Demon Sect. Judging from your identity, you are in the same position as him, you don't need to give a salute, and the people of my Hell Demon Sect never need to give a salute to others. ”

A proud voice sounded in Lei Yu's mind, it was a gloomy voice, which made Lei Yu have a feeling of sudden enlightenment. Thinking of this, the feeling of oppression in the soul suddenly disappeared, and it was replaced by a sense of relaxation.

His eyes were calm, his waist couldn't help but straighten up, and he completely regarded himself as a person of the same level as Zixiao Ancestor, with no fear, no flattery, only calmness.

The change in Lei Yu made Yin Yin couldn't help but smile, and also made Zixiao Ancestor can't help but glance at it.

"Who am I, it turned out to be you, I haven't seen you for a hundred years, it seems that you are alive and well, so I am disappointed for a while. Yin Ming's face smiled, but there was a mockery in his words.

Zixiao Ancestor just smiled, didn't care, and said, "The old man came here today, not for fun. Yin, do you remember the conditions you promised the old man?"

His voice was very loud and convincing, as if everyone would be convinced by what he said. If it was before, Lei Yu might have been confused by his voice, but now that Lei Yu's mentality has changed, he will naturally not be affected by it.

It's just that, despite this, Lei Yu still has a trace of doubt in his heart. At the beginning, in order to allow him to stay in the Zixiao Sect safely, Yin Ming and Zixiao Ancestor reached an agreement, Yin Ming needed to help Zixiao Ancestor find pure Yellow Spring Water in order to promote to the Golden Thunder Stage, and Zixiao Ancestor needed to help Yin Ming recover his strength.

Both sides take what they need, they just need to wait until he is promoted to the Thunder Infant Stage, go to the "Hell Demon Pool", and communicate with the Hell Underworld. And now that he has been promoted to the Thunder Infant Stage, it is time to fulfill the original conditions.

Lei Yu was sure that this battle Zixiao Ancestor had been hiding in the shadows, and he would definitely not allow Lei Yu to have an accident. As long as Lei Yu is really in danger of death, he will definitely take action immediately, after all, this is his only chance to be promoted to the Golden Thunder Period.

Lei Yu shook his head and smiled bitterly, secretly thinking that he had tried all his strength, but everything fell into Zixiao Ancestor's calculations, this feeling made him very unhappy, but what if he was unhappy, the gap in strength made him unable to resist at all.

"Of course I remember!" Yin Ming said, his eyes scanning Zixiao Ancestor's body for a moment, and a glimmer of essence flashed in his eyes.

"Your longevity is numbered, and you are so eager to get the water of the Yellow Spring!"

Yin Minghui's eyes are like beads, and he can see through the longevity of Zixiao Ancestor at a glance, the strong people in the Immortal Thunder Period are not immortal, 100,000 years of longevity is the limit of the strong people in the Immortal Thunder Period, and the Zixiao Ancestor can live for more than 100,000 years, mainly because he has taken a few anti-heaven elixirs, which has been able to live until now.

But the elixir is also exhausted, and the current Zixiao Ancestor has reached his twilight years, if he can't break through again, the last result is that his longevity will be exhausted and he will die out forever.

When a person dies like a lamp going out, whether it is a cultivator or a mortal, there will be such a result. If you want to live forever, you have to pay a price that is unimaginable to ordinary people, and cultivators are not as chic and comfortable as mortals imagine, on the contrary, in order to live forever, in order to become immortals, cultivators have been busy, and most of their time is spent in retreat and cultivation.

This is a kind of sorrow, even if he has the power to turn the world upside down, but after reaching the end, he still can't escape the causal cycle of birth, old age, sickness and death, and Zixiao Ancestor is no exception.

At the mention of this question, Zixiao Ancestor also fell silent. At this moment, Lei Yu could clearly see that Zixiao Ancestor's skin was not as bright as he imagined, but wrinkled, and in his hair, the snow-white silver threads were very eye-catching.

Zixiao Ancestor is really old, and the strength of the years cannot be resisted, even if the strength is boundless, but after all, he can't escape such an ending.

"According to the old man's estimate, there are still two hundred years of life!" Zixiao Old Ancestor's voice became gloomy, and the green tendons on his forehead revealed his true mentality, his desire for immortality had overwhelmed everything, so he would follow him directly, he wanted to get the water of the Yellow Spring, and he wanted to be promoted to the Golden Thunder Period.

"That's good, as long as it's not going to be done right away, there's still time. In fact, I don't want to go to the Hell Demon Pool now, after all, this kid's strength is still too weak, even if he goes to the Hell Demon Pool, he may not be able to communicate with the Hell Underworld and restore my strength, which means that you may not be able to get the Yellow Spring Water. ”

"But it's different now, since you still have a few hundred years to live, then this matter can be postponed, and it's not too late to do it when this kid is strong enough. ”

Yin Ming said with a smile, and decided this matter.
