Fang Yuan stared at the severed arm within the phantom golden bell, muttering to himself.
According to the *Biography of Song Zi Xing*, after Song Zi Xing rebelled against Ten Thousand Dragon Dock, he slaughtered his pursuers, then concealed his tracks, painstakingly built his power, and developed rapidly.
He had a long-term vision and was fully aware of his own situation. Thus, he specifically researched this killer move.
During the Central Continent Gu Refining Convention of that year, the ten great sects joined forces and set a trap, attempting to surround and kill Song Zi Xing. In the end, he actually managed to escape!
In this battle, Blood Demon Disintegration made its debut and amazed all of Central Continent. The majority of the credit for Song Zi Xing's escape went to this move.
This immortal killer move could form a flesh-and-blood clone in a short amount of time. The clone was extremely fast, comparable to the Blood Rainbow Flash. Moreover, it was lifelike and extremely realistic. Even an immortal-level investigative killer move would be hard-pressed to find a flaw in it.
However, the cost of using this method was also immense.
One needed to transform a part of one’s own body into a false flesh-and-blood body. It also required a massive amount of immortal essence to provide power and maintain the false body's existence. The more immortal essence consumed, the longer it lasted.
Gu Immortals had many methods for regenerating severed limbs. The physical loss from Blood Demon Disintegration was only a superficial phenomenon. In reality, it consumed the Blood Path Dao Marks on the body.
It was precisely because of these Blood Path Dao Marks that the mysterious power of Blood Demon Disintegration was achieved.
If not for using the Blood Path Dao Marks as the price, the flesh-and-blood false body formed by Blood Demon Disintegration would never have reached such a convincing level.
When an ordinary Gu Immortal was injured, for example, if Fang Yuan were attacked one day and lost most of his body, the Strength Path Dao Marks on him would all be reclaimed by his immortal aperture. When his body recovered, the Strength Path Dao Marks would once again adhere to his body.
Once a Gu Immortal died, all the Dao Marks on his body would be reclaimed into his immortal aperture. For example, the Fox Immortal Blessed Land.
After successfully executing Blood Demon Disintegration, even if the severed limb could regrow, the newly born flesh would be completely blank. The original Blood Path Dao Marks were all consumed along with the false body.
Without a doubt, the loss of Dao Marks was an immense loss for a Gu Immortal.
This was because Dao Marks were extremely hard to come by. They were only gradually accumulated by enduring Heavenly Tribulations and Earthly Calamities. Every time a Gu Immortal faced a tribulation or calamity, they often had to risk their lives, and their immortal aperture could be damaged, with their painstakingly managed resources destroyed in an instant.
Therefore, the cost for a Gu Immortal to obtain Dao Marks was extremely high.
From this, one could see the value of the Eating Immortal Gu.
But Fang Yuan could be certain. Song Zi Xing should not have an Immortal Gu similar to Eating Gu on him. Having lost his Blood Path Dao Marks, he would have to undergo tribulations again and slowly accumulate them anew.
The Dao Marks on a Gu Immortal's body could effectively increase the power of Immortal Gu and Immortal Killer Moves. The degree of this amplification was terrifying; at the Rank Eight level, it could increase power by hundreds or thousands of times. Therefore, a Rank Seven Gu Immortal could rarely fight against a Rank Eight existence.
*The Biography of Song Zi Xing* recorded that Song Zi Xing escaped without a trace and survived. In the end, only a head and half a chest remained; the rest of his body was resolutely abandoned. He had utilized Blood Demon Disintegration.
In this battle, the ten great ancient sects of Central Continent lost a lot of face. They did not achieve their goal and were instead toyed with by Song Zi Xing. They suffered heavy casualties.
Song Zi Xing's losses were also extremely severe. He lost a fierce blood dragon bat, an ancient desolate beast, and most of the Blood Path Dao Marks on his body were destroyed. This battle caused him to not show his face in public for over two hundred years afterward. He was even missing without a trace for a time, leading people to suspect that he had died.
However, by the time he re-emerged in the world, not only had he fully recovered his battle strength, he had even nurtured three fierce blood dragon bats!
Such a major event as the ambush on Song Zi Xing, Fang Yuan naturally knew clearly.
He looked at the severed arm, a faint heat flickering in his eyes.
This severed arm and hand came from Song Zi Xing; it was the flesh and blood of his original body. As long as Fang Yuan obtained it, he could refine Song Zi Xing's head using Gu refining techniques.
And Song Zi Xing's head was the sole condition for the Star Constellation Blessed Land's Land Spirit to acknowledge a master!
Land Spirits were beings that stuck to rigid logic. As long as Fang Yuan took out Song Zi Xing's head and gave it to the Land Spirit, he could become the master of the Star Constellation Blessed Land. The Star Constellation Land Spirit would not care whether Song Zi Xing was still alive or not.
It was just a pure obsession, formed by combining the land will with the blessed land's heavenly and earthly might.
Fang Yuan could become the master through this. Even if, one day in the future, Song Zi Xing bounced and jumped in front of the Land Spirit, the Land Spirit would not betray Fang Yuan.
Because the conditions for acknowledging a master had already been truly achieved by Fang Yuan.
However, at this moment, subduing this arm was still a bit troublesome for Fang Yuan. Breaking the Golden Bell was not difficult, but once the Golden Bell phantom shattered, the arm would explode and turn into a sky-covering cloud of blood mist.
Fang Yuan had to use other methods to promptly suppress the severed arm, otherwise he would be drawing water with a bamboo basket and end up with nothing.
In fact, Fang Yuan's impression of this arm was also quite profound.
His current location was on the edge of the Zhen Yang Mountain Range, near Yuanyang City.
Song Zi Xing's severed arm was wrapped in an immortal killer move. The Gu Immortal who performed the move was busy chasing Song Zi Xing and had long forgotten this arm. As time passed, after one night, the golden bell would disperse, and the arm would explode into a blood mist.
At that time, the blood mist would cover several hundred li in all directions, causing widespread suffering and leaving a deep poison for ages to come.
For the next several hundred years, the Yuanyang City side would continuously issue quests, recruiting talented individuals to go deep into the blood mist and slay the blood beasts that were constantly being incubated within it, preventing the blood beasts from forming a beast tide that would assault Yuanyang City.
In his past life, when Fang Yuan traveled to Central Continent, he had lived in Yuanyang City for a period of time. To survive, he had also accepted the quest to eradicate blood beasts.
From this point of view, Fang Yuan coming here early to subdue Song Zi Xing's severed arm was actually a good deed.
Fang Yuan observed for a moment, then carefully used several mortal killer moves to test it.
The Golden Bell phantom remained steadfast, worthy of being an immortal killer move.
Fang Yuan also continuously circled the phantom golden bell, observing it from every angle, trying to find a suitable method.
The golden bell phantom was not purely still, but rotated slowly. Inside, the severed arm hovered in the air, and a flash of bright red blood light flickered on the arm and hand from time to time.
After circling more than a dozen times, Fang Yuan already had a plan in his heart.
He was just about to make a move when suddenly his ears moved, and he heard many sounds.
"An explosion... did you hear it too?"
"...It... is... saw a strange light..."
