White Luna wielded Light Power; her spiritual power and Star Power were both at grade B.
Black Luna wielded Dark Power; her Strength, Agility, Body, and Defense Qualifications were all at grade B.
However, by using the soul bond of "Gemini," both of them could simultaneously reach a 6B qualification.
But such powerful soul power had a flaw.
They couldn't be separated for long periods, so usually, one of them would fall asleep.
During the day, White Luna controlled the body while Black Luna slept inside.
At night, they would swap control of the body, along with synchronizing their memories.
Just now, even without White Luna summoning her, Black Luna had woken up sensing her sister's danger.
Several seconds passed; though the power of Void Shattering had begun to wane, Black Luna's body only sustained minor scratches under the attack, without being torn apart.
Moreover, the black patterns on her body grew deeper, and her powerful physique started breaking free from the twisted void's bindings.
At this moment, Su Yuan made his move.
Silver light rose beneath his feet; Su Yuan directly used Teleportation to swap places with Black Luna and appeared right in front of White Luna.
Black Luna hadn't synchronized memories yet, so she hadn't witnessed Teleportation before. Seeing Su Yuan wielding a knife before White Luna, she was instantly shocked.
White Luna's expression changed dramatically; she desperately gathered Star Power to manifest the defensively countering Holy Light Body.
However, Su Yuan's knife-wielding action was naturally faster; he swung the blade down.
Blood spurted; White Luna didn't even have time to scream before Su Yuan decapitated her!
"Damn it!" Black Luna's face contorted, eyes filled with intense coldness and anger. "You actually killed my sister?"
Su Yuan looked at Black Luna and couldn't help but frown.
On her face, besides anger, there were no signs of grief or sorrow.
This was extremely unreasonable unless Black Luna wanted to monopolize the body. For twin sisters sharing a single soul, there should be deep feelings.
At this moment, Black Luna touched her chest. Suddenly, a light-dark mark appeared.
Su Yuan's expression shifted; his eyes silver gleamed as he activated All-Knowing Vision to look at White Luna's corpse again.
Soon, Su Yuan faintly sensed an invisible soul energy rising from the corpse.
"So it really isn't that simple."
A cold light flashed in Su Yuan's eyes. He raised his hand, unleashing several Boundary Breaking Lines.
However, the Boundary Breaking Lines passed through, doing no harm to the soul energy.
Before long, the soul energy entered the light-dark mark on Black Luna's chest.
Afterward, White Luna's decapitated body turned into pure white light and disappeared.
"So sharp…" Black Luna frowned at Su Yuan. "But ordinary energy and physical attacks cannot touch the soul."
As Black Luna spoke, white light appeared on half of her body. Her originally black eyes and hair gradually turned black and white like the original Luna.
"Could it be…" Su Yuan thought of something.
In the next moment, black and white light split from the center, transforming back into the two sisters.
"What pain!" White Luna stroked her neck, her beautiful face filled with intense anger.
Since receiving Holy Blessing and significantly advancing her soul power, mastering resurrection, this was her first use of it!
Though resurrected, the pain of decapitation and the trauma of her first death made White Luna's expression extremely grim.
"So they can resurrect…" Su Yuan narrowed his eyes, contemplating rapidly.
Clearly, this was a trait similar to the Poison Fire Two-headed Python encountered during middle school trials.
But the Poison Fire Two-headed Python merely regrew a head when one was chopped off, equivalent to having a spare body part.
However, the Gemini twins were two completely separate entities. Their resurrection technique far surpassed the Poison Fire Two-headed Python!
Su Yuan's mind raced, devising three countermeasures.
One, even with such unique abilities, there must be a limit to this abnormal resurrection method. It couldn't be infinite reincarnation.
Thus, continuously killing them until they couldn't resurrect was a possibility.
But if they could indeed reincarnate multiple times, it would be extremely troublesome.
Not to mention whether Su Yuan could manage it, the resources and methods required would be immense, and this battle wouldn't only involve the Gemini twins as enemies.
Two, since one could revive the other, simultaneous defeat was necessary, like dealing with the Poison Fire Two-headed Python.
Su Yuan calculated earlier. From Black Luna revealing the light-dark mark on her chest to White Luna's soul leaving her body and entering Black Luna, restructuring took roughly a minute.
As long as he could kill both within a minute, they could be dealt with.
With Void abilities, Su Yuan might even get a chance to directly pierce both.
Although direct and feasible, this strategy held high risk and unpredictability.
Not to mention the need to carefully create opportunities, he hadn't yet seen Black Luna's full capabilities.
