The System, being in this space, could also see the appearance of the parasite through the body's perspective.
Tang signaled the System to throw an appraisal at it, but the System indicated that it couldn't.
They couldn't affect things that were in a 'being observed' state, and appraisal was also impossible.
This space and dimension were far higher than the real world and the spirit world. Without meeting certain conditions, they could only be like readers, unable to interfere with the story's progression.
But this also had its advantages.
"It's only a shallow parasitism."
Tang, like a ghost, followed behind the baby-faced knight.
He found that he could clearly hear the conversation between the baby-faced knight and the parasite within him, although this also consumed a lot of spirituality. But he had borrowed a lot.
His future self was really generous, the spiritual power borrowed was much more than several Sequence Five selves combined.
"If I really borrowed spirituality from my future self, then that self who lent the spirituality must have at least reached Sequence Two, or even Sequence One."
A powerhouse of that level had a vast amount of spirituality, and lending some wouldn't affect them at all.
So, extending this further, could he borrow other items besides spirituality from his future self?
For example, the Sun Scepter with its missing Extraordinary characteristics completed? Or other marionettes and magical items his future self controlled?
Or, for example, borrowing the System that might have already devoured the God of Craftsman or the Hidden Sage in the future?
Even just a few seconds would be enough for him to play some new tricks.
"Hiss, thinking about it this way, the Yesterday Once More charm is much more powerful than I thought."
Of course, this had to be experimented with and the rules figured out before it could be used as a trump card.
Whether he had to use the Yesterday Once More charm within Euclid's space to borrow power from his future self, or if he could leverage this power in the real world as well.
Moreover, the power of the Yesterday Once More charm hadn't reached its peak.
The essence of a charm was to pray for power from a high-level existence and use materials that could bear it and corresponding symbols to fix the obtained power.
The theater core had no object of prayer. The Yesterday Once More charm was also a type of charm. Praying to oneself and responding to one's own prayer, with only the Sequence Two Miracle Worker level theater core, without the Gray Fog participating in the response, the Yesterday Once More charm it created wasn't at its best.
Naturally, the total amount of power requested from the past self would also decrease.
Moreover, the spirit worms remaining in the theater were not many.
After becoming a Sealed Artifact, the theater core could no longer autonomously split off corresponding spirit worms. The spirit worms currently used to make Yesterday Once More charms were all the theater's previous reserves. Hmm, this also needed to be resolved.
Should he rob the Secret Order and catch a few Trick Sorcerers to split spirit worms for him to play with every day?
Old Zaratul was dead, and Little Zaratul might still just be an ancient scholar...
Noting down the little calculations in his heart, Tang, with the support of divinity and a large amount of spirituality, found that under this close observation, he could 'flip open' some information about the person he was observing like turning the pages of a book.
Tang waved the Sun Scepter in his hand, and the power of spirituality caused the baby-faced knight's figure to gradually collapse from three-dimensional to flat, unfolding like a paper doll.
Then, the paper doll's flat body flipped page by page, and dense text flooded into Tang's spirit body at once.
He could certainly refuse. The power of divinity could resist this influx, but Tang didn't stop it.
This was inherently part of testing the rules.
"Being in this space, there are no secrets to the things being observed."
Like characters in a filed book, big and small events were recorded in detail.
"What's this called, Heaven's Door (note)?"
Tang roughly reviewed the transmitted information, which was the life history of the baby-faced knight, and then summarized again.
"The more detailed, the more spirituality is consumed."
"Even for an ordinary person, if you want to browse their entire life in detail, the spirituality required is equally enormous."
Tang looked at the middle-aged man beside him.
As a parasite, he was only shallowly parasitizing an ordinary person, just using this to hide himself.
He could only see everything the host saw and hear everything the host heard, but he couldn't interfere with the host's thoughts or steal his ideas.
This shallow parasitism was difficult to affect the host but also indirectly showed that this parasite was not like Amon.
Of course, it might also be a disguise.
After Tang confirmed that this wasn't some avatar of Amon trying to enforce the law, he prepared to browse the other party's history.
However, browsing the information of this parasite required hundreds or thousands of times the spirituality of the baby-faced knight.
The heaviness in front of him prevented Tang from compressing this middle-aged man's body into the shape of a paper doll. While ensuring his spirituality was sufficient to do other things, he could only read some basic information about the other party.
However, after reading it, Tang's expression became strange again.
"Ha."
Pales Zoroaster.
Sequence One, Time Worm.
Was Tingen this lively?
Never-Ending Theater.
Tang squatted on the ground and dry-heaved twice, relieving the dull pain in his brain caused by the exhaustion of his spirituality.
A stack of Yesterday Once More charms was placed on the table, and the War Bishop marionette, now re-controlled by the theater core, stood aside, watching Tang squatting on the ground.
Tang prayed to the theater, and after receiving a response, his spirituality was soothed.
After leaving Euclid's space, the System retrieved the Sequence Four Extraordinary power from his body and then re-established contact with Tang, liberating the Extraordinary characteristics of the Master of Marionettes. Only then did he return to his body, retreating from the pseudo-demigod state.
"This time's harvest is quite a lot."
'Host, what's wrong with your spirituality?'
The System asked curiously.
After rebinding with the host, the abnormality of Tang's previous spirituality value also appeared in the System's logs, and it discovered the problem.
The War Bishop marionette also cast a gaze at him at the appropriate time.
"How to put it," Tang slumped into the chair, feeling somewhat languid due to the exhaustion of his spirituality, "Something unexpected happened."
He picked up a charm on the table and then used it.
The Yesterday Once More charm transformed into a historical gap, allowing Tang to see the ocean, mermaids, and himself advancing to Master of Marionettes.
He saw the Never-Ending Theater, saw himself preparing the theater, also saw the Sun Scepter, saw the Knowledge Wilderness, and saw himself floating in mid-air.
That was himself in the 'Observer' level.
But he didn't borrow the power from when he was at that level, because that level's self was full of mad knowledge, and the power brought by the Yesterday Once More charm would probably disappear in a few seconds.
After all, these were all illusions.
Note: Heaven's Door, a Stand in JOJO, whose ability is to turn people into books and read all the information about them on the pages.
