"I'll give you one last chance to die or hand over the tiger bones." Lin Mu said coldly.

"Nirvana is extremely difficult to survive. If there is no devil and tiger bone, I will die a lifetime, so I might as well fight to the death." Vigorously gritted his teeth.

"Then you just die." Lin Mu said coldly. He didn't have the Tiger Clan's body-refining exercises to exchange with the Vigorous Earth Splitting Tiger. Since the other party was unwilling to hand it over, he could only grab it.

The vigorous vitality condensed into a Suzaku in the sky, and the raging flames wrapped the whole body, exuding an extremely terrifying power.

"I am willing to surrender the tiger bones of the Heavenly Demon." Feeling the arrival of death, the Earth-Splitting Tiger was still softened. When he handed over the tiger bones of the Heavenly Demon, it still had a chance to survive.

"Don't play tricks on me, otherwise I will let you know that death is sometimes a luxury." Lin Mu said indifferently, the Vermillion Bird in the sky slowly faded, and finally disappeared.

"Don't dare." The Vigorous Earth Splitting Tiger broke out in a cold sweat, and immediately turned back to the cave. After a while, there was a rush of heavy steps in the cave.

The figure of the Tiger Vigorously reappeared again, carrying a black skeleton that was several feet long on his shoulders.

With a loud bang, the black skeleton was placed on the ground, and the entire valley trembles suddenly, the weight, even Lin Mu was a little moved.

The skeleton is pitch black, shimmering with the luster of fine iron, as if cast by metal, exuding a vicious atmosphere.

"It's worthy of being one of the three big tiger races in the monster beast world." Lin Mu was secretly speechless.

Lin Mu put the Heavenly Demon Tiger bones into the Universe Bag, and in the unwilling and helpless eyes of the Tiger Vigorously, he took Qingtan and left the Beast Valley.

After leaving the Beast Valley, Lin Mu did not leave this virgin forest, but found another secluded valley, because Xiao Lei was about to hit Nirvana.

Breaking through Nirvana is very important to Xiao Lei, even Lin Mu dare not care.

"I have enough Nirvana Pills here. Don't worry about breaking through." Lin Mu said lightly. After speaking, he took out one million Nirvana Pills and formed a torrent of Nirvana Pills.

Xiao Lei let out a low roar, rushed into the Nirvana Pill torrent casually, and began to impact the Nirvana Realm.

The pill of Nirvana turned into the air of Nirvana, and was continuously sucked into the body by the small thunder. Soon, the strong air of Nirvana completely enveloped him.

All Lin Mu could do was to wait and protect Xiao Lei.

The time for the monster to break through the Nirvana Realm was longer by humans. Lin Mu had waited for three full days. In the middle, Xiao Lei had absorbed the one million Nirvana Pill, and Lin Mu invested another 500,000 Nirvana Pill.

When the brilliance of the early morning on the fourth day shrouded this mountain range, the 500,000 Nirvana Pill was almost absorbed by Xiao Lei.

"Roar--"

A low growl came from the crimson nirvana, and then a suction force was generated. All the nirvana was like a river returning to the sea, swallowed by Xiao Lei.

Xiao Lei's figure appeared in front of Lin Mu again, the crystal armor on his body exuded a faint golden luster, and the wings on his back shone with cold blades like blades.

"Successful." Lin Mu smiled happily.

Xiao Lei did not come, instead, like a human, sat down on the spot, and a crimson flame emerged from his body.

"Xiao Lei is planning to cross Nirvana?" Qing Tan asked somewhat unexpectedly.

"The monster beast can only complete its true transformation after it has passed Nirvana." Lin Mu said.

In the next half day, the hot fluctuations that erupted in Xiao Lei's body became more and more terrifying. Fortunately, Lin Mu and Qingtan had already entered the Nirvana Realm and were not affected.

When this hot wave reached a peak, it began to slowly weaken.

As the temperature rose and fell, a thick mist appeared around Xiao Lei, and his vision became extremely hazy.

When the fluctuations completely disappeared, Lin Mu's spirit suddenly lifted, looking into the thick fog, heavy footsteps came out of the thick fog, and then a figure walked out of it.

As soon as the figure came out, Lin Mu blocked Qing Tan's eyes.

This figure is exactly the transformed Xiao Lei, about the same size as Lin Mu, and three points similar in appearance to Lin Mu, except that he has just transformed, and he has nothing on him.

"Hurry up and put it on." Lin Mu took out a set of his own clothes and threw it over.

"Thanks...Thank you...Master." Xiao Lei was still a little unaccustomed to speaking, took the clothes, and put them on with some jerky movements.

"Since it has been transformed, call me eldest brother later." Lin Mu smiled. Although Xiao Lei's blood is not as good as the Devil Tiger, it is a bit stronger than the Vigorous Earth-Splitting Tiger. The first Nirvana is already Completely transformed into a human form.

"Big Brother." Xiao Lei smiled stiffly.

"Are you Xiao Lei?" Qing Tan looked at the transformed Xiao Lei curiously.

"It's okay to call Xiaolei, but you have to have a surname. Just follow my last name, Lin Lei. From now on, I will be your elder brother and Xiaodong will be your second brother." Lin Mu said.

"What about me?" Qing Tan asked.

"You are the youngest, still your younger sister." Lin Mu smiled.

"That's okay, I have another brother." Qing Tan smiled playfully, revealing two small crescents, not because it was his younger sister.

"Xiao Lei, do you have a weapon?" Lin Mu asked.

"No." Xiao Lei shook his head. With his current strength, he couldn't build a spirit treasure for himself.

"No, it doesn't matter, wait until I find the right materials to refine a heavenly spirit treasure for you." Lin Mu smiled, Xiao Lei's bloodline is still a little worse.

"Yeah." Xiao Lei nodded.

Lin Mu's fingers touched Xiao Lei's eyebrows, and passed Lei Yuan Gong and Lei Shen's body to Xiao Lei.

"This is my cultivation technique, and you are also of the Thunder attribute, and you can certainly practice it." Lin Mudao, Lin Dong can practice the dragon clan's practice, and it is not impossible for Xiao Lei to practice the human practice.

"Thank you, brother." Xiao Lei smiled.

"Brother Lin Mu, where are we going next?" Qing Tan asked.

Lin Mu heard the words and thought about it carefully. Now that the ancient secret store is still several months away, he needs to find something to do during this period.

Looking for opportunities?He doesn't have that interest. For him, those inheritances are very tasteless. What he needs is Nirvana Pill, a lot of Nirvana Pill.

"Let's go to robbery." Lin Mu smiled.

"Robbery?" Qingtan said in a bit of astonishment.

"The ancient secret store will be opened. As long as the dynasty in the northwestern region thinks that it has some strength, it will definitely come to this ancient temple. We will definitely gain a lot of gains by blocking the road on the only way to the ancient temple. "The corner of Lin Mu's mouth raised slightly.

In the Great War, there were not only one hundred dynasties, but in the northwest region, the number of dynasties exceeded one hundred, and the number of high-level dynasties was not a minority.

And with his strength, there is no need to worry about any danger, even if he is under siege, but he can't beat him, it is always okay to retreat.

"Okay." Qing Tan said with a playful smile. In her bones, she was still a rebellious little witch.

"I also helped Big Brother grab them." Xiao Lei said in a daze.

"Well, after Xiao Lei is fully familiar with his body, we will set off." Lin Mu smiled.
