The first five times of the thunder tribulation, it is generally yin thunder, and the black peach wood is to absorb a trace of thunder and lightning power into the tree body and store it when experiencing the yin thunder tribulation, and then slowly refine and absorb it, but the amount absorbed at one time cannot be too much, otherwise it will be destroyed by the thunder and lightning! And if you want the heart of the tree to turn all black, you need to go through at least five Yin Thunder Tribulations, otherwise the heart of the tree will not all turn black.

And after experiencing five Yin Thunder Tribulations, the peach tree can generally transform into a human body, so if you want to get it, it's impossible! Some Taoists who have an organic fate get black peach wood in the deep mountains, and that is also because the peach tree failed to cross the catastrophe, and finally turned into a body and was obtained.

Although the peach tree has turned into a human body, they have no dodge the hundred-year tribulation, and after turning into a human body, the power of the heavenly tribulation is naturally much stronger, so some peach trees have to hide in the inaccessible mountains when they cross the tribulation.

As for the Yin Yang Peach Tree, it is the body of the Wood Immortal who has experienced the Ninth Heavenly Tribulation, and the first five Peach Trees have experienced the Yin Thunder Heavenly Tribulation can absorb the power of thunder and lightning into the body, making their bodies more and more tenacious, so as to resist the later Heavenly Tribulations.

And from the sixth heavenly tribulation, thunder and lightning are not ordinary thunder and lightning, but yang thunder, the role of yang thunder is to cross the peach wood from the demon body into the immortal body, and those who are absorbed by the peach wood into the body of the power of yin thunder, you can use the ground to resist the impact of yang thunder, so that your body will not be destroyed!

When the last bit of black yin thunder in the immortal wood is dispersed by the yang thunder, the peach wood will be the real immortal body! But how difficult it is to survive the Heavenly Tribulation, some Wood Demons were hacked to death during the first Heavenly Tribulation, and those who can cultivate to nine Heavenly Tribulations are estimated to be unable to count on one hand since the beginning of the world.

And the peach tree in front of Xiao Yu was not able to withstand the Yang Thunder Tribulation during the Ninth Thunder Tribulation, so the spirit dissipated, and the black left in his body was the part left by the Yin Thunder, and the white was the part that had turned into a wood immortal, so it was called the Yin Yang Peach Tree by the cultivators.

It takes at least 1,500 years for a Yin Yang Mahogany to form, because it takes 100 years for a tree to open its spiritual wisdom, and then it will experience a Yin Thunder Tribulation every 100 years, and the subsequent Yang Thunder Tribulation will descend once every three years, so it is said that there are at least 1,500 years.

Looking at this yin and yang peach tree, Xiao Yu seemed to see his grandfather, they were all the same, they had been fighting for the unattainable immortal dream all their lives, but in the eyes of the Heavenly Dao, thousands of living beings were like grass suke, no matter how devout you were to the Heavenly Dao, but in the eyes of the Heavenly Dao, you were just a tool that he could drive.

Just like this yin and yang peach tree, he cultivated from a weak peach tree to a spirit body, and then passed the test of layers of thunder tribulation in order to seek the avenue, but in the end he died under the thunder tribulation, and his thousand-year-old cultivation turned into a bubble, like a flash in the pan.

Xiao Qiang saw that Xiao Yu looked at the wood and didn't speak, and immediately asked, "Xiao Yu, what are you talking about Yin and Yang wood, is this thing useful?" ”

"Dad, this peach tree doesn't need to be sawed," Xiao Yu said with a deep breath.

"If you don't saw it, isn't this tree heart useless?" Xiao Qiang asked suspiciously, he was holding a chainsaw before, so he naturally knew that this seemingly rotten wood was actually very hard in the heart of the tree, and he cut the heart of the fist for more than ten minutes, but only cut a small crack.

"It's useful, but you can't cut it with a chainsaw, it's easy to hurt the wood, you wait for me" Xiao Yu dropped a sentence, walked back to the house quickly, and walked out with this talisman, but now Xiao Yu's face looked very dignified.

Yin Yang wood is different from ordinary wood, if it is an ordinary lightning strike wood, it only needs to be treated simply, and it can be used, but Yin Yang wood is a half-immortal body, and the tree body contains stored fairy qi, if it is not handled properly, it will not only let the fairy qi dissipate, but also the power will drop a lot.

"Dad, you stand farther away" Xiao Yu stood in front of Taomu and said solemnly.

When Xiao Qiang saw Xiao Yu like this, he immediately took two steps back suspiciously, and was about to ask, but he didn't want Xiao Yu's eyes to close slightly, holding the talisman in one hand, and sliding quickly on his chest with the other hand, and whispering what it was.

Xiao Yu's mother walked in from the courtyard at this time, and when she saw where Xiao Yu was standing, she was about to go to say hello, but was stopped by Xiao Qiang, and then the two stood behind and looked curiously.

At this moment, Xiao Yu's eyes opened suddenly, and his feet quickly stepped up the Tiangang Beidou step in the courtyard, every time he took a step, Xiao Yu had to chant two sentences, Tiangang Beidou step is evolved according to the arrangement of the Big Dipper, but this is not a simple seven steps, but forty-nine steps, which is the evolution of the Maoshan Patriarch according to the Tiangang Beidou, which has a huge spiritual attraction effect.

Forty-nine steps, Xiao Yu from the beginning of the very slow, to the end faster and faster, although each step does not seem far, but has a unique law, and look closely, you will find that Xiao Yu walked the Tiangang Beidou step actually wrapped the peach wood in it, when the last step fell, Xiao Yu quickly slid a circle with one foot in the place, and then stepped on the circle two points, as if stepping on the yin and yang.

Then Xiao Yu waved the talisman in his hand, and shouted in his mouth, "Sanqing Tianzun, merciful sentient beings, open the talisman spiritual fire, burn the dry body, Tiangang Big Dipper Seven Star King, bless the wood immortal to die in vain, the heavenly spiritual light, the earth spiritual light, one spirit and one light worship the heavens, the heavenly immortals, the yin Cao soul, help me open the immortal fire door, urgent as the law."

After reciting the incantation, Xiao Yu suddenly threw out the talisman in his hand, and then said, "The fire burns the dead wood, and it is reborn when it encounters fire."

The talisman flew out lightly, but landed on the peach tree accurately, and then with a bang, the whole peach wood seemed to be poured with gasoline, and ignited a flame more than two feet high, but this flame was not the usual yellow-red, but with a hint of pale.

Xiao Qiang's eyes were like copper bells, and even Xiao Yu's mother nervously grabbed Xiao Qiang's arm, not daring to make any sound.

Xiao Yu saw that he had successfully ignited the peach wood, and immediately sealed his hands and continued to step out of Tiangang, but this time he stepped out of Tiangang, but it was not as easy as before, and without taking a step, Xiao Yu felt that his legs were heavy, and if he didn't take a step, Xiao Yu had to stand there and rest for a while, and then continue to step out.

The seemingly dry mahogany grew smaller and smaller under the scorching flames, but the flames grew higher and higher, and the flames began to twist like a man, as if something was about to escape.

Seeing this, Xiao Yu hurriedly sat cross-legged on the ground, sealed his hands, and quickly clicked on the flame a few times, and after these few clicks, the flame became normal again, and Xiao Yu stood up and continued to walk Tiangang, but now, Xiao Yu's face became more and more pale, and finally after taking the last step, a mouthful of blood spit out.

"Xiao Yu .....".

"Ahh.......h

Xiao Qiang and his wife saw Xiao Yu suddenly vomiting blood, and couldn't help but exclaim, and they were about to rush over, but Xiao Yu stretched out his hand to stop them, Xiao Yu understood that now this is the last step, if it fails, this Yin Yang Wood Sacrifice will fail, so now, Xiao Yu has to hold on no matter what.
