The sovereign immortal body is the body formed from sovereign immortal fetus Gu, whose dao marks do not conflict.
Ordinary Gu Immortals absorb dao marks only from an enemy of the same path. Fang Yuan can absorb dao marks from any enemy he kills and treats that as the best way to raise his foundation. Spectral Soul wanted to revive using this body. ch. 1127 The Gu sits on Sovereign Immortal Fetus Gu.
First injury
That lack of conflict between dao marks is also a disadvantage. When a rank seven Gu Immortal pierces Fang Yuan’s left arm and stomach, fragmentary ice and snow path dao marks engrave the wounds and make them hard to heal. The sovereign immortal body’s disadvantage appears for the first time, and he is easily injured. ch. 1141
Free passage and a local aura
The sovereign immortal body lets Fang Yuan travel through regional walls easily and alter his aura completely so he becomes a local. Hei Lou Lan and the others carry Northern Plains aura, which passes in Eastern Sea but draws strong ostracism from locals in Southern Border, Western Desert or Central Continent. ch. 1154
Defense weakness
Non-conflicting dao marks are a huge advantage and a major flaw. Once an attack penetrates his defenses, he takes the damage fully. The attacks are not weakened by the dao marks in his body. ch. 1179
Annexed dao marks
When Fang Yuan annexes Han Dong blessed land, he absorbs all of its dao marks instead of the usual reduced take. Ordinary Gu Immortals, even those of the ten extreme physiques, face conflicts between different dao marks when annexing immortal apertures. The sovereign immortal body does not, so every path’s dao marks can stay. Spectral Soul deduced sovereign immortal fetus Gu and refined it through great danger. Non-conflicting dao marks make the body fragile, but Fang Yuan judges the advantages far greater. ch. 1185 Annexing another Gu Immortal’s aperture ordinarily costs the annexer some of the dao marks gained and sacrifices future growth potential for a short-term gain; Ying Wu Xie notes the sovereign immortal body is exempt from that cost. ch. 1184
Dragon transformation
In ancient sword dragon form Fang Yuan has a sturdy and strong body, but the sovereign immortal body’s characteristic of non-conflicting dao marks still exists. He reads ancient sword dragon transformation as strong offense and weak defense with an extreme imbalance between the two. ch. 1205
No restriction crossing a regional wall
Weighing whether to flee through Eastern Sea’s regional wall, Ying Wu Xie knows that ordinary Gu Immortals risk their immortal apertures shaking and severe backlash from using Gu worms or immortal killer moves inside one, but the sovereign immortal body’s nature lets Fang Yuan travel through regional walls freely, without any such restriction. ch. 1253
An advantage in healing
The sovereign immortal body is the main reason Bai Ning Bing’s freezing sight works so well on him, and without the ancient sword dragon’s tough body and strong vitality a human body might have been frozen to death. The same lack of repulsion also helps him recover. Because his dao marks do not repel a wound’s other dao marks, mortal healing methods can still take effect on him even when used repeatedly. This is unlike Tai Bai Yun Sheng, who cannot be healed easily once injured. ch. 1258
Taking the region’s aura
Once he passes a regional wall, the sovereign immortal body lets Fang Yuan shift his own aura to match that region’s, so he reads as a native Gu Immortal and blends in completely. ch. 1272
Fast natural recovery
After a failed attempt to improve the killer move vajra shell with a rank one mortal Gu leaves him with minor injuries, Fang Yuan judges the injuries small enough that Man as Before is unnecessary, and that he will recover in a couple of days on the sovereign immortal body’s recovery speed. ch. 1314
