A look of complacency spread across the Purple Crane True Person's face. In the terrifying situation around them, his demonic nature was fully revealed.
"Look at these corpses. They are all the stepping stones on my path of exploring spiritual roots."
"The only difference between a cultivator and an ordinary person lies in the presence or absence of spiritual roots. But what if I sew a cultivator and an ordinary person together?" the Purple Crane True Person said. "As soon as this idea came to me, I immediately started looking for people to experiment on."
"Ordinary people are too weak to withstand such injuries. But later, I used the Corpse Puppet Secret Technique and supplemented it with pills, so that ordinary people could be sewn together with cultivators while still alive."
"Although they survived, the results were extremely disappointing to me. Ordinary people would die from extreme pain, and no pill could suppress it. If two cultivators were sewn together, both of them would be in excruciating pain. There was no such problem with two ordinary people. It can be seen that the spiritual roots are playing some kind of role in this."
"Well, isn't my experiment very bold?"
This old monster even set up a control group...
However, the medicine in the cultivation world is really advanced. It's actually possible to sew two strangers together without causing death.
From his description, it's obvious that the spiritual roots are incompatible and cause rejection reactions.
The pain must be roughly similar to the pain of tearing out spiritual roots...
Xu Shan still remembered it vividly. Just one pull could make his whole body paralyzed and make him foam at the mouth.
If he hadn't been bewitched by the Kun Beast back then, he definitely wouldn't have been able to withstand Zhang Biao's continuous tearing of his spiritual roots.
It's hard to imagine how one could hold on if that pain originating from the soul persisted.
Xu Shan suppressed his nausea and asked, "Then what? Did you solve the problem of the pain?"
"No, I didn't solve it at all. I've tried repeatedly and can confirm that that kind of pain is impossible to eliminate." The Purple Crane True Person said regretfully. Then, he changed the subject and said, "But I did all these just to seek an answer. Whether the pain is eliminated or not doesn't matter."
As he finished speaking, a spine as white as mutton fat jade appeared in the Purple Crane True Person's hand, and he stroked it obsessively.
Xu Shan looked at the white jade spine in shock, and his eyebrows began to throb!
This... What the hell is this! Fragrant oil?
The Green Seal was starting to absorb it, but it seemed that this spine was very difficult to absorb.
There was just a throbbing feeling between his eyebrows, but it was only slightly warm, not the kind of intense heat he had felt before.
This bone seemed very difficult to absorb...
The Purple Crane True Person didn't notice anything unusual at all. Holding the spine, he murmured and reminisced in front of Xu Shan.
"Many years ago, the cave of an ancient cultivator in the depths of the Southern Border was unearthed. This place was called the Ancient Immortal's Tomb, which attracted countless powerful people to fight for it. This spine and the Wugou Xuanshu that you cultivate were both obtained from the tomb. For these, I almost suffered a great deal. I even took the risk to cross the Sunken Spirit Sea and seek refuge in the Righteous Path."
"These two things are actually the complete inheritance of that ancient cultivator! The strength of this person is the strongest I've ever seen in my life. Good magic tools will be decayed after tens of thousands of years, but his bones are still as good as new. But I don't know which powerful expert killed him when he was alive. All his bones were broken, except for this spine."
"That ancient cultivator should have been lingering on the verge of death at that time. He sacrificed all his cultivation and refined it into this spine. The spinal cord even became a rare treasure that's hard to find in the world. What's more interesting is that he should have been eager to pass on his inheritance at that time, and he also left a method of using the spinal cord. This method can even lead ordinary people to the path of the Supreme!"
The Purple Crane True Person paced around, patted Xu Shan's shoulder, and let out a long sigh: "Feeding the Nether Spirit with his spinal marrow can cultivate a spiritual root that has never been seen before in the cultivation world! A living spiritual root that can even cultivate on its own!"
"The noblest and the lowest things in the cultivation world can actually be combined. And the characteristics of the Nether Spirit make the spiritual root it transforms into can be used by anyone."
"Unfortunately, those were just the speculations of the ancient cultivator before his death... I tried this method, but in the end, it still failed. The Nether Spirit that absorbed the spinal cord dissipated..."
Xu Shan was greatly stirred and swallowed hard!
A living spiritual root, wasn't that just like Zhang Biao?
He crossed the Sunken Spirit Sea and went to the territory of the Righteous Path. Maybe it was in the Shuijing Domain, at the Chiyun Temple!
That is to say, the so-called fragrant oil is actually the spinal cord of the ancient cultivator?
The possibility is too high... It's almost certain!
Did he have such a connection with the Purple Crane True Person?
The Purple Crane True Person seemed to be a bit carried away and said to himself, "After knowing that this method didn't work, I almost went crazy... Hehe, but as the saying goes, there's always a way out!
"The Ancient Immortal's Marrow was used up, but there's still this spine left! And this spine is actually the key. Back then, the ancient cultivator actually only refined the spine with all his strength. The Ancient Immortal's Marrow was just transformed from the spine."
"As long as the spine of someone else is replaced with the spine of the ancient cultivator, there will be a chance to nurture the Ancient Immortal's Marrow again."
"But once this bone is transplanted into the body of a cultivator or an ordinary person, they will feel extremely painful."
"At first, I thought it was a problem with this spine. But after many experiments, I made an astonishing discovery. It's not the problem of the spine, but that when it's transplanted into the human body, it will transform the spiritual roots, and even ordinary people will develop spiritual roots because of it and be able to sense the spiritual energy!"
Feeling the warmth between his eyebrows, Xu Shan asked, "Then the problem of the pain has never been solved. Even if a spiritual root is cultivated, what's the use of it?"
A smile appeared on the corner of the Purple Crane True Person's mouth: "Of course it's useful. I have a Blood Refining Living Corpse Technique, which can make the recipient stay between life and death, unable to feel the pain, and can also be connected to the mana of the controller."
"Unfortunately, it takes time to use this technique. Before you, five people tried to transplant this bone, but none of them survived more than a stick of incense because of the intense pain. I need at least two sticks of incense time. And only you have the chance to hold on."
"As long as I refine you, we can witness the peak together! We can be master and disciple for life after life. What do you think of how I treat you?"
Xu Shan took a deep breath: "Go to hell! If you have the guts, kill me now!"
Instead of getting angry, the Purple Crane True Person laughed and looked at Xu Shan, saying, "Do you know why I'm telling you all this?"
"Firstly, because I can't hold it in and need to talk. Secondly, because I appreciate you. If I didn't have this inheritance of the ancient cultivator, I really often thought about accepting you as my direct disciple!"
"Oh?" Xu Shan sneered, "Is this some kind of comfort before you kill me?"
"No, no, no." The Purple Crane True Person shook his head and smiled faintly, "I was born into a humble family, and my talent was so low that I only had a lower-grade spiritual root. I struggled in the cultivation world for a hundred years before I could barely show my head. I would pounce on any opportunity like a mad dog and never give up! How many times have I lingered on the verge of crisis and tossed between life and death to achieve what I am today."
"I see the shadow of my youth in you... You are just like me back then. Even in the face of numerous crises, you still risk your life to desperately improve yourself and strive for a place in the world."
Xu Shan looked puzzled.
The Purple Crane True Person looked at him squarely and said, "Yang Lin... You killed her, right?"
