Dora used to be a school teacher on a certain blue planet. One day, her students 'pranked' her by throwing a fake plastic spider at her. Terrified, she backed off, fell, hit her head on the ground, and died.

Transmigrators usually die by getting hit by trucks, asteroids, lightning, etc.; her death was quite unusual for transmigrators.

In any case, after transmigrating into this world and going through the first few phases of shock, denial, and depression, she finally accepted her fate.

Her system, or golden finger, as some call it, was quite powerful; despite being reborn into a mortal's body, her life has never been in danger.

It is called the 'Simulation' system; it allows her to 'simulate' her own future, therefore knowing all future events and anything that may threaten her. If she dislikes the result of a simulation, she can 'overrule' it and change it to her liking.

This basically means she can change the entire world's future as long as she dislikes it. After all, her future is not standalone; changing events in her future changes the whole world alongside her.

Still, she can't overrule everything; some things are 'unoverrulable,' meaning they must happen in all futures.

One such unoverrulable event has been the appearance of vampire kings. She has seen that vampire kings will start appearing and causing huge disasters in the future. In one recent simulated future, she was killed by one such vampire king.

She tried to overrule it and prevent vampires from becoming widespread, but she failed. She only managed to change her own future so that the vampire king missed her and killed her neighbor.

That result wasn’t satisfactory; if it all goes like this, millions would die at the hands of vampire kings. Unfortunately, she lacks the ability to stop it.

She was transmigrated into this world about 20 years ago; she was born into an aristocratic family. Her family spent a lot of money and sent her to a small immortal cultivation sect. Even though she was quite talented, she only managed to reach the 1st stage of the Energy realm in 20 years. After all, this area is a low-energy zone; even the existence of cultivation sects can barely be maintained.

The local big sect, StrongSoul Sect, doesn’t care at all about mortals living in low-energy areas. In ancient times, the sect used to perform immortal cultivation tests and take disciples even from low-energy zones, but in modern times, it stopped caring at all.

This area is said to be under the control of the IcePower Immortal Master, who doesn’t care about mortals and has a non-intervention policy. In ordinary times, it is good that immortals don’t interfere with mortals. Still, once a disaster like the vampire kings happens, the lack of strong cultivators could lead to the inability of the local population to fight it off.

"How can the StrongSoul Sect be so irresponsible? With IcePower in closed-door cultivation, there is little hope of any help from strong cultivators!" she thought in annoyance.

Her knowledge about the world is much higher than one may expect; after all, her system has the ability to perform one simulation every hour. By now, she has performed tens of thousands of simulations, each and every one of which would help her uncover secrets and important information.

Each simulation continued until her death; in some of the simulations, she reached high levels of cultivation and lived for tens of thousands of years. Fortunately, the system has a memory management function, which allows her to seal most of the memories in the system and visit them only when needed. Otherwise, with memories of billions of years, she would have already gone crazy!

The most strange thing is that until just a few months ago, in none of her simulations she had ever seen any trace of vampire kings; they appeared only recently, seemingly with no apparent cause.

Cultivation level: First stage of the Energy realm

Simulation: Ready

Teaching: Locked

Disciples: Locked

Divine protection: The abilities and skills of other systems do not work against the host.

Seeing that the simulation was ready, Dora activated it without hesitation; whenever the simulation was ready to be performed, she would not hesitate at all.

"Simulation has been successfully performed: At the age of 23, you finally manage to break through to the 2nd stage of the Energy realm. Your sect master admires your talent and appoints you as the young lady of the sect. At the age of 27, you encounter a vampire king; using your lifesaving treasure, you barely manage to run away. At the age of 29, your sect was attacked by a powerful vampire king; you barely were able to run away, but your sect master and most of your fellow disciples and sect elders died."

"At the age of 35, you finally reach the headquarters of the StrongSoul Sect and are accepted as a disciple. At the age of 38, you break through the 3rd stage of the Energy realm; the concentration of energy is much higher, and the StrongSoul Sect gives much more resources, so your cultivation speed increases tremendously. At the age of 40, you break through the 4th stage. You accept a sect mission and complete it without issue. The StrongSoul Sect sends investigators to check the situation with the vampire kings; the investigators return and report that the issue is not serious and that the vampire kings are at most as strong as the 4th stage of the Energy realm. You protest, but as a disciple, nobody listens to you; the StrongSoul Sect puts the matter of the vampire kings aside and won’t send any help."

"You broke through the 5th stage of the Energy realm at the age of 45. You receive news indicating that a vampire king has attacked your family, and the survivors ask you to send help. Looking at the date of the letter, you notice it is from two years ago. You curse at the terrible post company and ask the sect for time off to go and check on them; the sect refuses. You curse again but don’t dare disobey the sect. At the age of 49, the sect investigators inform you that vampire kings killed your family."

"You broke through the 6th stage at the age of 51. You broke through the 7th stage at the age of 56. You broke through the 8th stage at the age of 63. You broke through the 9th stage at the age of 72. Finally, you broke through to the peak and the 10th stage of the Energy realm at the age of 90. At the peak of the Energy realm, your lifespan is around 2,500 years. You are considered one of the most talented of the new generation of the sect and are rewarded with many cultivation resources."

"To prepare for breaking through to the Element realm, you intended to accept sect missions; however, Elder Graceful Night, one of the most influential elders of the sect, accepted you as her disciple. She provided all resources you needed to cultivate; you no longer had any need to accept any missions."

"Breaking through to the Element realm was not easy; it took you 200 years. Finally, at the age of 290, you managed to break through to the Element realm. By this time, low-energy zones are under the rule of vampire kings; a vampire king managed to break through to the Divine Soul realm in only 200 years and started threatening the wellbeing of mortals who lived in the StrongSoul Sect's territory."

"The StrongSoul Sect couldn’t allow the vampire kings to advance any further; the chief elder of the sect, at the Void Soul cultivation level, set off to destroy the vampire kings."

"X killed you."

"Again!" Dora sighed. Recently, most of the simulations had the same ending, and she had failed to change it no matter what she did.

"I want to overrule," Dora said to the system.

"Specify," the system said.

"I would survive until at least the age of 1,000," said Dora.

"Overrule failed," the system prompted.

"The sect master didn’t set off to kill the vampire kings."

"Overrule successful!"

"Simulation continues."

"The StrongSoul Sect couldn’t allow the vampire kings to advance any further; the chief elder of the sect, at the Void Soul cultivation level, wanted to destroy the vampire kings, but in the end, he didn’t go there personally; he sent Elder Graceful Night to eliminate the vampire kings."

"X killed you."

"I want to overrule," Dora said again; each simulation has 3 overrule opportunities.

"Specify," the system prompted.

"The sect master didn’t send anybody; he ignored the vampire kings!" she said.

"Overrule successful!"

"Simulation continues."

"The StrongSoul Sect couldn’t allow the vampire kings to advance any further; the chief elder of the sect, at the Void Soul cultivation level, wanted to destroy the vampire kings, but in the end, he didn’t. He thought that other immortal forces would probably deal with it, so there was no need to pay any attention. In any case, Master IcePower ordered not to interfere with mortal affairs."

"At the age of 350, you broke through to the 2nd stage of the Element realm. You accepted a sect mission. On your way, you discovered a secret nest of vampire kings; you went back and reported it to the sect. The sect master was furious; he immediately set off to destroy them personally."

"X killed you."

Dora sighed and decided to try again, even though she knew it most likely wouldn’t work.

"I want to overrule."

"Specify."

"No one from the StrongSoul Sect ever attacks the vampire kings."

"Error! Overrule is only available for one specific instance."

After getting the expected results, she finally chose her final overrule chance.

"I would run away from the sect before the sect master set off to kill the vampire kings!"

"Overrule successful!"

"Simulation continues."

"You left the sect to look for opportunities. At the age of 310, you received news of the destruction of the StrongSoul Sect; the entire sect grounds were under a sea of blood. You were terrified and ran away."

"On your way to the north, you met a vampire king as strong as a Substance Soul cultivator."

"Vampire king Spring Breeze killed you."

"End of simulation."

Dora shook her head and decided to do another simulation one hour later to discover more details.
