After sending Casey Palug away, Lu Xiao returned the time in the isolation room to normal, and the Chaldean personnel responsible for monitoring him found no abnormalities.
"I didn't expect that the fourth beast, one of the disasters for mankind, would worry so much about the life and death of a mere human being."
Lu Xiao whispered with some emotion: "Conquering the enemy without fighting, Ma Xiu's merits are immeasurable."
Ma Xiu is not Lu Xiao's first "patient". Lu Xiao has accumulated a lot of experience in treating physical defects. Treating Ma Xiu is just a "minor surgery" for Lu Xiao.
The problem is time.
Whether it is repairing or directly replacing the body, Ma Xiu will need a certain amount of time to adapt again, and it is impossible to plug and play like Lu Xiao, who masters the materialization of the soul.
The battle for the Temple of Crowned Time is about to begin, and Chaldean staff are working day and night to calculate the coordinates of the temple, striving to complete the final step of restoring human nature in the shortest possible time.
Calculating based on Chaldea's work progress axis, it will take about one month.
One month may be barely enough time for Ma Xiu to complete restorative training, but just in case, Lu Xiao decided to adopt a safe plan and postpone the treatment process until the end of the war.
…
To the Chaldean staff, Lu Xiao, who voluntarily accepted surveillance and isolation, was undoubtedly a weirdo.
Since arriving in Chaldea, Lu Xiao has never left her room, and she doesn't care about the strict surveillance 24 hours a day.
Most of the time, Lu Xiao sat cross-legged on the ground meditating. Occasionally, he would stand up suddenly and make inexplicable gestures with his fingers in the air.
When Leonardo da Vinci looked at the surveillance screen, he had a thoughtful expression on his face.
She had some contact with Lu Xiao when she was at the Sixth Singularity. Although she didn't know much about him, Da Vinci always subconsciously believed in the information and suggestions provided by Lu Xiao.
'Parallel world?'
Da Vinci curled his fingers and tapped his forehead lightly.
Strictly speaking, Chaldea's spirit transfer experiment is to project the Master into various parallel time and spaces in human history.
As one of the three heroic advisors summoned by Chaldea and a famous omnipotent man in history, Leonardo da Vinci was no stranger to the theory of parallel worlds.
Heroic Soul is an existence transcending time. Although he did not obtain memories related to Lu Xiao in this incarnation, Da Vinci still retained some vague impressions in his soul and subconscious.
Every time a heroic spirit returns to the Throne of Heroes, its memory will be sealed. This is a rule set by the two major inhibitory powers.
But rules are dead and people are alive.
One's own willpower is one of the important reference data for recovering memory, and Gilgamesh is a typical example.
On the other hand, the deeper the contact with a companion with whom you have a strong bond, the greater the possibility of recovering your memory.
Using the legend of his heroic spirit to manifest the familiar yet unfamiliar painting, Da Vinci compared Lu Xiao with the person in the painting many times to confirm that he was the person depicted in the painting.
"A close friend..."
With a frown, Da Vinci tapped her forehead harder, and some deep memories in her mind began to slowly revive.
Lu Xiao was meditating in the room at this time, comprehending the gift left by King Hassan.
According to Wang Hassan, the gift he gave Lu Xiao can only be truly understood after death.
At first, Lu Xiao thought that what Wang Hassan left behind was guidance on awakening the Demonic Eye of Death, but it turned out that he wanted to start a fight.
King Hassan himself is the incarnation of death. He can cut off various concepts of existence without the assistance of the magic eye.
After more than ten days of quiet understanding in Chaldea, Lu Xiao gradually understood the secret.
What the owner of the Eye of Direct Death can see is the target's death line. As long as it is cut along these lines, regardless of whether the target is a living thing or an inorganic object, its own concept of existence will be completely destroyed and cannot be repaired by any means.
Lu Xiao had already come into contact with the source after the Fourth Holy Grail War, and involuntarily received a lot of useful and useless knowledge from that magic vortex, including part of it related to the concept of death.
What Wang Hassan left behind was not an external auxiliary "device" like the magic eye, but an intuitive understanding of the origin of death.
To put it simply, Lu Xiao can now vaguely see the weaknesses of the target.
It is not a monotonous dead line, but a very three-dimensional conceptual weakness with complete points, lines and surfaces, which can be seen even without special activation of abilities.
Just like the room where he is now isolated, Lu Xiao has at least a thousand different ways to cut through the wall and leave easily without using force to crush it.
"Um?"
Da Vinci's gaze projected through the surveillance camera was noticed by Lu Xiao.
With a thought, Lu Xiao erased the "colorful" anatomy diagram of things and turned his attention to the camera Da Vinci was using.
From Da Vinci's perspective, Lu Xiao suddenly turned her head to face the camera with a half-smiling expression, and then a low voice of inquiry came from behind her.
"Leonardo, do you need my help with anything?"
da Vinci:"!!!"
Da Vinci was not frightened by the sudden sound from behind, she had already heard who the sound came from.
In the surveillance screen, Lu Xiao was still meditating with his eyes closed with a faint smile on his face. When Da Vinci turned around, he strangely saw another Lu Xiao.
"...How did you do it?"
Lu Xiao shrugged: "It's just a clone pulled from the past time gap."
During this period of time, Lu Xiao seemed to be staying in the isolation room honestly, but in many cases the staff saw his clone in the same position.
These clones were manifested by Lu Xiao from a certain timeline in the past. They look no different from the real person in appearance, and they can also perform a series of actions according to Lu Xiao's orders. They can be fake and real.
Just like now, after noticing Da Vinci's gaze, Lu Xiao immediately created a clone, turned on the aura blocker and sneaked into the control room quietly, just in time to catch Da Vinci.
Lu Xiao sat quietly on the chair in front of the monitoring station, crossed her legs and looked at Da Vinci leisurely: "I know you have a lot of doubts in your heart, just ask them, and I will answer whatever I can."
Da Vinci was also a man who had experienced many storms. The many strange adventures Fujimaru Ritsuka experienced in the seven singular points also gave her a lot of knowledge.
"Then I'll keep the story short."
Da Vinci took a deep breath and asked the question he cared about most first.
"What was our previous relationship?"
Lu Xiao: "?"
"Is this question worth asking?"
Looking at Da Vinci's stubborn expression speechlessly, Lu Xiao spread his hands and sighed: "Just like the name of the painting, we are close friends who can trust each other in life and death... But I promise there is no deeper relationship."
