Lin Xian stepped back.
Gazing at the eight gleaming password wheels underneath his nameplate on the locked safe:
20240328
This sequence of eight numbers formed a date, marking the 20th birthday of Chu Anqing, as well as the day she vanished into blue stardust.
In fact, until today, when Lin Xian decided to set the password, he had never considered what kind of password he would choose.
He simply thought that any complex password would suffice.
Even a simple one would do.
After all, safes are meant to deter honest people, not thieves. If his dreams were illusory and crafted by the enemy in a fake studio, the enemy could certainly have cracked the hafnium alloy safe within 600 years using brute force, peeked at the note inside, and reproduced a copy for him to see.
The password wasn't important.
What mattered was the content of the note and needing a fixed reference point like the safe to ensure that he would see the note 600 years later.
