The Memory Trimmer

‌ Chapter 1: False Memory Clinic ‌

Neon lights in Manhattan, New York, cast weird DNA spirals on Jiang Xia's quantum incense burner through bulletproof glass. The underground memory repairman was using his brain Neuron Universe device to erase the trauma of a car accident when he realized that the red Toyota in his memory had never existed in the same advertisement ten years ago.

"Mr. Lin, are you sure you bought it in 2013..." Before the words were finished, the customer's pupil suddenly turned into a data vortex. Jiang Xia's nano-repair machine buzzes, and the memory that should have been erased in the hologram begins to erode in reverse - the non-existent car radio is retelling her breakfast in binary code.

‌ Chapter two: The Jet Lag Hunt ‌

Three days later, Jiang Xia woke up under the Brooklyn Bridge with a countdown light code on her wrist: 71:59:23. The piers are plastered with wanted posters of themselves of different ages, the latest one labeled "2042 Mastermind of financial crimes across time and space."

The man in the dark grey trench coat came out of the morning mist, his right hand a prosthetic-modified cause-and-effect meter. You've altered too many memories, and now 40 parallel universes are coming to kill you." He took off his sunglasses. "By the way, I'm you in 2035."

Jiang Xia's cold smile solidified in the corners of her mouth - the man has the same lacrimal mole scar below her left eye, which was beaten with a data cord by a memory dealer at the age of 16.

‌ Chapter 3: The Black Market of memory ‌

When they broke into the underground auction in the Gangnam district of Seoul, Jiang Xia finally understood the source of those abnormal memories. "Memory packs of the 2024 Bitcoin Crash" float on the holographic booth, and ladies are bidding on "first love that never happened."

"The memory black market uses dark matter to build a false timeline." The future activates its own EMP device, "The so-called car accident you deleted last week was actually from another universe..."

The auctioneer suddenly turned into countless pixels burst, and Jiang Xia was pushed into the escape channel. The last image seen is of the 2035 self fending off the Time police's boson bullet with his body, and the meter in the pool of blood shows a countdown: 00:07:44.

‌ Chapter 4: The embroidery of Cause and effect ‌

Tokyo Shibuya intersection, Jiang Xia in the jet lag under the siege to start the ultimate solution - the memory repair device stabbed into the back of the neck. The pain made her see the warp and weal of all the timelines: those deleted memories swam like goldfish in a pool of cause and effect.

"So I see." Dipping her nose into a Starbucks napkin, she calculated, "Every tampered memory is a silver needle pierced into time and space, and the collective human subconscious is the loom that embroiders parallel universes."

At the moment when the countdown returned to zero, Jiang Xia used a laser pointer to engrave the McBius ring code in the retina. The pursuer's time weapon suddenly recoils as it touches her skin, and the entire street contracts into a singularity like crumpled tinfoil.

‌ Chapter 5: Recursive life ‌

At the top of Seattle's Rainier Snow Mountain, Jiang Xia watched seventy-two parallel worlds of himself emerge from the morning fog. Some of them carried Judgment Day files, some wore neurological crowns, and the youngest version even held their infant selves.

"A memory restorer is a time hole." The future itself, first encountered, rises from the snow, quantum foam oozing from a bullet hole in its chest. "Now it's your turn to be the anchor."

Ginger Xia ignited the final quantum incense, neon-colored incense ash in the air to form the Klein bottle structure. As all the parallel selves melted into her body, the LED facade of the Bitcoin exchange suddenly flashed a 2013 Toyota AD - the red car that the customer had not remembered.

‌ Final chapter: Missed calls ‌

Three months later, a teenager in an Internet cafe in Tokyo found a strange live broadcast on the dark net: a woman wearing a white coat presented both youth and old age on the operating table. As the camera gets closer, all the audience phones receive a voice message from 20 years ago:

"Your memory repair appointment will begin now, counting down to 71 hours and 59 minutes...
