Chapter 15 Summary
"So far, we have sent three time-space text messages. I think it is necessary for us to summarize the patterns and mysteries involved."

Jiang Ran pulled the small blackboard to the front of the lab bench, writing on it while summarizing:

"The first time a time-space text message was sent was purely by chance, a lucky coincidence."

That's a very apt description.

The coincidences at the time were just too extreme.

While packing up his things, Yan Rui, a senior student from the film club, found an old positron cannon. Out of curiosity, he placed the positron cannon on the table, which happened to be aimed at the transformer distribution box outside the window.

After the positron cannon was activated, it burned out the circuitry and caused a power outage after only 0.7 seconds of operation.

In this 0.7 seconds, the positron beam bombards the high-voltage transformer, creating a spacetime black hole that lasts for exactly 0.7 seconds.

Jiang Ran happened to be standing next to the distribution box at that moment, and happened to press the send button within those 0.7 seconds, sending out the text message radio waves.

Thus, the spacetime black hole captured the radio waves, traveled through time and space back to the past, and transmitted them to three days earlier, completing a completely accidental spacetime text message transmission.

This event was purely a low-probability coincidence; with so many "coincidences," a slight mishap could have prevented it from happening.

"The second time-space text message transmission was our first test after we repaired the positron cannon."

This was just a test experiment.

No one was sure they would succeed, but they did.

The test text message was successfully sent three days ago, and history was changed, causing the timeline to shift once again.

The experiment itself was perfect, except for...

Cheng Mengxue received two text messages on her phone.

The second text message appeared out of nowhere, and the mysterious garbled numbers on it have yet to be deciphered.

Jiang Ran continued writing on the blackboard:

"【The third time-space text message】is the first time we have actively sent a text message after we have grasped certain patterns, in an attempt to actively rewrite the trajectory of history, actively trigger a timeline jump, and try to revive Xu Yan who died unexpectedly."

This attempt is crucial.

Because it is purposeful... a challenge to established history.

This is the opening of Pandora's box.

It was the beginning of an attempt to manipulate history.

It is a verification of the worldline theory.

It is proof of the power to control space and time.

……

Jiang Ran put down the chalk and brushed the chalk dust off her fingertips:

"Through these three experiments, we have basically mastered the principles and usage rules of time-space text messaging. Xiaoxue, it's your turn."

"Coming!"

Cheng Mengxue had been writing on the whiteboard paper.

She stood up, picked up the magnet, and pasted the whiteboard paper covered with large writing onto the small blackboard:
"This is what I just summarized... the rules and key points about time-space text messaging. I'll go over them one by one."

On the whiteboard, written in bold:

Time-Space SMS User Manual (Version 1.0)

[1. Time-space text messages can only be sent up to three days ago.]

2. The sending window for time-space SMS messages is only 0.7 seconds.

3. After the positron beam is overloaded, it needs to be powered off and left to stand for 20 hours before it can be used again.

[4. The successful sending of the text message will trigger a change in spacetime, which only Jiang Ran can perceive.]

[5. Changes in spacetime represent leaps in world lines, but only Jiang Ran possesses "full spacetime memory."]

?

Jiang Ran stared at the last one:
What is "Full-Time Memory"?

"The name I gave you because of your special constitution."

Cheng Mengxue, hands on hips:
"Isn't he handsome?"

"That's so cringeworthy..."

"Wow, what a perfect definition! The previous explanation was too wordy; we need to be more concise."

She tried her best to persuade them:
"With so many shifts in the timeline, haven't you retained your memories each time? Those lost histories of time that none of us remember... are all in your mind."

"Since you possess memories from every timeline, naming this special constitution 'All-Timeline Memory' would be the perfect name!" "Whatever you say." Jiang Ran felt it didn't matter what it was called.

He looked at the "Time-Space SMS User Manual (Version 1.0)" and pondered...

in fact.

Many of these rules may not be absolutely accurate.

However, since this is a provisional version, it's fine as is for now.

If we make new discoveries later, we can update to version 2.0 or 3.0.

Then.

Next.

Qin Feng summarized it.

"Let me share my thoughts on this positron cannon."

Qin Feng walked to the experimental table:

"The principle, structure, and effect of this device are all unknown. Anyway, I don't believe it can actually emit a positron beam. Okay, it does seem to emit some energy, but I must say, it absolutely cannot be a positron beam. Physics doesn't allow it."

"Get to the point," Jiang Ran interrupted.

"Because we dare not disassemble the core components, the research progress is very slow."

Qin Feng continued:
"But I feel that time-space text messages can't just be sent to three days ago. There must be some variable that can control the 'depth' of the time-space black hole to send the text message to an earlier point in time."

"For example, ten days ago? A month ago? A year ago?"

possible.

Jiang Ran had thought about this before.

"So, in the next experiment, I plan to try to find this variable."

Qin Feng pointed at the positron cannon:

"The electron beam density can be changed by controlling the intensity of the beam concentrate through an external circuit."

"I think it's very likely... that by increasing the electron beam density, we can send text messages to even earlier points in time!"

Jiang Ran nodded:
"You can try it, but I suggest you don't increase the density first. Try decreasing the density first... How about sending text messages from two days ago, one day ago, or even a few hours ago?"

Qin Feng smiled:

"You're as cautious as ever, but you're right, it's safer that way."

"Not only that."

Jiang Ran extended his index finger:

"Since we're going to conduct experiments, let's explore as many possibilities as possible."

"Next time we send a text message, we can have a different person send it, or a different phone send it... and see if you can also retain your memory across all times."

Currently.

Why I possess "full-time memory" remains an unsolved mystery.

He had thought about it before.

Could it be related to who sends the text message or who presses the send button?

Although this is very mysterious.

But since we have no ideas, let's try some metaphysical methods. Maybe we'll just stumble upon something by sheer luck.

"All right."

Jiang Ran glanced at his watch; it was 9:01 PM.

The dormitory building will close in two hours, which is enough time to conduct a time-space text message experiment.

"Now that we've finished summarizing, let's get started on the experiment without further ado."

He cleaned the blackboard.

Write the words "The Fourth Spacetime SMS Experiment" in large characters.

Then she turned around and smiled slightly:
"Now that there is no need for testing and no emergency to salvage, we are completely free to decide the content of the time-space text message."

"So, let's brainstorm together—"

"What kind of thing are we going to do this time using time-space text messaging?"
