Their commission was suspicious.

"Wait, let me see... Oh, the most perfect part of this plan seems to be an option to restore all the saved people's memories of the apocalypse after the rescue. The original intention seems to be to ensure that the saviors' contributions are not forgotten..."

Those who hold salaries for everyone must not freeze them to death in the wind and snow.

[That makes things even easier. Search for destroyed worlds, find someone to save them, and you'll get feedback after the salvation, a large amount of "lie elements," and the potential Primogems reward for completing the quest. Three birds with one stone.]

The only problem is... the historical changes that might result from altering history.

"If we're talking about the end of the world and the apocalypse... you might say the Yellow Springs..."

[You really are just lusting after her... otherwise why would you keep thinking about her?]

"I'm warning you, don't talk nonsense. I'm only paying a little more attention to her because she looks like Mei, and also because her hometown was destroyed." Chen Luo quickly shook his head.

[It's hard to say. It'll be quite difficult for Huang Quan to obtain it. First, as the envoy of nothingness, does he still want to save the world? After all, nothingness pursues the idea that all things are illusions. Second, even if he defeats the so-called gods of Takamagahara, the Void Star God will easily take his head.]

“That is a problem…” Chen Luo nodded.

It could be said that whether it's Izumo, the invaded country, or Takamagahara, the invader, even if one side achieves a complete victory, they may ultimately still be unable to escape the final "nothingness."

"But there is a way to break the deadlock, or rather, this way to break the deadlock is applicable to the entire planetary world."

"Hmm? What method?"

[Find Aha. That rascal wouldn't mind saving a planet from the clutches of the Void Star God if he could just get Aha's attention. But attracting Aha's attention is the problem, because those saviors can only recall memories.]

"Are you a genius?" Chen Luo was greatly shocked.

Chen Luo hadn't initially thought of this solution.

My father once said that we should use the Star God to fight the Star God.

The Void Star God did not intentionally want to touch Izumo, where Yomi resides, or Takamagahara, which was in conflict with it. The destruction of these two worlds was simply due to their bad luck.

The Void Star God is extremely powerful, but the opponent is just slacking off.

Ahha once sent a group of young people to the Void Star God to help them assassinate him, so naturally he could also save the unlucky soul who was about to die from the Void Star God's unconscious actions because of fun.

"I think we should stop calling this world the Locomotive World or the Starry Sky Railway World and just call it '100 Ways to Use Aha,'" Chen Luo complained.

The user-friendly plugins really take Aha to a whole new level.

The key is that Ahha is easily hooked by the lure of fun.

Because the God of Laughter was used because of Laughter, this whole thing is just too hilarious! Long live Laughter!

Chapter 2197 Chen Luo: Next... do I need someone else to fulfill my wish?

"If you don't want to save the world, just say so. I won't force you." Chen Luo sighed as he looked at Saeko Busujima in front of him.

Chen Luo is the kind of person who will try anything he thinks of.

After obtaining the Savior achievement, my first reaction was naturally to give it a try.

Whether it's an achievement or a prop, beyond the surface description, there are often deeper things waiting for Chen Luo to explore.

The world that Chen Luo can think of most easily to save right now is the zombie world where Highschool of the Dead is located.

The dark world of bullets probably can't use the third, most perfect method of redemption: time travel. In that world, those who want to save the world can't do anything if they go back to ten years before the apocalypse began, and those with the power to stop the disaster ten years ago don't have enough faith to support them going back ten years.

Hopeless.

Fortunately, the dark world of bullets still has a large number of Paradise Adventurers active in it, killing Gastrea to gain experience, which has led to a significant decrease in the number of Gastrea in this world.

As the range of human activity in this world gradually expands, sooner or later, all the Gastrea creatures in the world will be wiped out by the adventurers of Paradise.

This, too, can be considered a form of salvation.

At most, the rescue wasn't thorough enough, and it's difficult for humanity to recover to its former glory in a short period of time.

But this can be considered as doing everything one can to be kind and righteous.

As for the pre-civilization... the pre-civilization did not need to save the world. Besides, the pre-civilization was destroyed 5 years ago. Who can go back 5 years?

After Chen Luo rescued all the people from the pre-civilization, even those who were most eager to save the world would have their faith in saving the world diminished considerably due to this external factor.

In this case, even the Thirteen Heroes could not go back 5 years.

The later the world is destroyed, the more feasible the third method will be.

Therefore, the only option is the world of Highschool of the Dead.

When Chen Luo arrived in this world and explained his ideas to the world consciousness, the world consciousness did not refuse. In any case, the world consciousness originally planned to reopen the world and did not know how to make it develop, so it let Chen Luo do as he pleased. Anyway, no matter what changes were made, it would not be worse than it is now.

But Chen Luo never imagined that he might die before even achieving his goal.

The reason, of course, was Saeko Busujima, who was looking at him apologetically.

As the chosen representative of this world's consciousness, Saeko Busujima, having also become an adventurer in Paradise, and possessing a rather unique personality... is a top-tier choice in terms of strength, spirit, and resilience. However...

"My lord, I am truly sorry." Saeko Busujima knelt before Chen Luo in a dogeza (a traditional Chinese kowtow) posture.

"...I never expected you couldn't even go back 10 days. Just how much do you like this chaotic world?" Chen Luo complained.

Although the user-friendly plugin advised Chen Luo not to waste time on Saeko Busujima, sending someone else to rewind wouldn't cost Chen Luo anything, and the experience of failure was also valuable, so Chen Luo ignored the objections and chose Saeko Busujima.

But Chen Luo didn't expect Saeko Busujima to fail so decisively.

"..." Saeko Busujima said nothing.

"Alright, I'm not blaming you. After all, everyone has their own ambitions," Chen Luo said.

Saeko Busujima possesses a unique bloodlust. Had she been born in a chaotic era or in ancient times, with her talent, she would undoubtedly have become a renowned swordswoman.

Unfortunately, in modern times with extremely comprehensive laws and regulations, this characteristic has become a shackle.

The emergence of the apocalypse allows the other party to completely let go of themselves.

Therefore, it is indeed very difficult to send Saeko Busujima to try to save the world.

Because her father was not dead, but living well in America, her desire to save the world was really low.

Fortunately, the Paradise was the medium that allowed her to find a place to vent her bloodlust even after being saved in this world. Otherwise, Saeko Busujima might not have been able to rewind even for a day, let alone last for 10 days.

However, failure also has its advantages; at least it allows Chen Luo to collect some lessons learned from failure.

“From your failed experience, I’ve learned a few lessons. First, if you don’t successfully save the world, everything you do in this timeline will be lost; in other words, your progress isn’t retained. This means it’s impossible to complete the apocalypse by having someone repeatedly play through the game and keep retaining their progress,” Chen Luo said to Saeko Busujima.

Meanwhile, Saeko Busujima was taking notes on the key points Chen Luo mentioned.

Saeko Busujima's lack of desire to save the world doesn't mean she doesn't want to save the world; it just means her obsession isn't that strong.

Anyway, if this world is saved, Saeko Busujima can go on adventures in other worlds.

"Secondly, although repeating a strategy won't save your progress, you can choose the one with the highest progress and complete it. Even if you don't completely save the world, a world that has been intervened in is always better than the status quo that hasn't changed."

As Chen Luo finished speaking, he looked at the save file that only he could see.

Current backtracking count: 2

[Should we implement worldline coverage?]

[Warning: You only have one chance to cover the world line.]

After seeing this prompt, Chen Luo chose to give up.

The first save file was created by Chen Luo himself, while the second save file featured Saeko Busujima.

Chen Luo's time rewind was slightly better than Saeko Busujima's—11 days.

If Chen Luo clicks on this save file, he can see what changes will occur after this save file is overwritten in this world line.

The change is nothingness.

Saeko Busujima can't even go back to when she first met Chen Luo, let alone save the world.

Chen Luo's handling of this world after arriving has been mostly optimal, and he deserves some credit for the fact that so many people are able to survive in this world.

Chen Luo remembered that after arriving in this world, he dealt with the zombie problem.

Therefore, when using backtracking as a savior method, as long as it doesn't backtrack to the original critical node, the changes it can make to the current pattern are basically negligible.

"It's a real pity that this time-travel ability can only be used by one person at a time. Otherwise, having hundreds of thousands or even millions of survivors team up to save the world would be much more efficient," Chen Luo sighed.

“Yes. But the world is already very lucky. At least with the help of adults, the casualties are not as serious as we imagined,” Saeko Busujima said respectfully and admiringly.

“Putting nice things on is useless. My obsession with saving this world isn’t that deep. That’s my third discovery. If someone from outside this world uses the ability to rewind time to try and save it, their identity after going back to the past is random,” Chen Luo said.

“Random…isn’t that a good thing? According to you, there’s no limit to the number of times this backtracking function can be used. As long as we can randomly select someone of high status and power, wouldn’t saving the world be much easier?” Saeko Busujima said.

“This is the fourth problem. For people outside this world, like me, using the ability to rewind might be more difficult than for those directly involved in the apocalypse. It might be because the sense of immersion isn’t high enough, or it might be the price of the advantages brought by a random identity.” Chen Luo shook his head.

The idea that outsiders would want to save the world is likely to be less appealing than that of the people involved due to a lack of immersion, and the cost of random identities adds to the problem... It's probably unlikely that outsiders can help save the world.

This probability is probably even lower than the probability of someone from within the world going on an adventure to the Dimensional Sea and encountering a world-class item as soon as they step out.

Thinking about it now, that guy, Chikujoin Shinkan, is really lucky.

"Yes, so it's just low, not nonexistent."

"Then, my lord, I will go and find someone who can save the world. Is there anything else you wish to entrust to me, my lord? Or is there anything else you require?" After summarizing the key points Chen Luo had mentioned, Saeko Busujima said.

"Requirements... I have a list here that specifies who can be selected. Just go and find them." Chen Luo took out a long list and handed it to Saeko Busujima.

"As expected of the master, he has already made preparations long ago."

"...Don't always praise me like that, I'll get arrogant. Actually, with the ability to scout and devise strategies using the Book of Akasha, the requirements for the other party's identity aren't that high. As long as the other party can hold out until they can go back to before the apocalypse and act according to the plan I gave them, saving the world won't be difficult," Chen Luo said.

Especially when this world is the everyday world.

While being able to bring memories back to the past is a significant limitation, knowledge is sometimes extremely important.

However, the strong always have some advantages when they go back in time. For example, after going back in time, Chen Luo discovered that his physical condition was better than the physical condition of the person he possessed in his memory.

There are some preferential treatments, but not many.

Chen Luo had already prepared a blood sacrifice formation that could enhance the physical attributes of people without magic power through blood sacrifice, and even summon meteorites.

When the time comes, just summon a meteorite and scatter the ashes of the research institute, and the apocalyptic crisis will naturally end.

However, when using the blood sacrifice formation, various problems often arise, such as the difficulty of collecting blood.

You can buy pig's blood or duck's blood, but that's inefficient. Human blood is the most efficient.

Therefore, the optimal solution is to make the other party a master assassin at the memory level, then enhance their combat power so that their strength increases after returning to the past. Then, relying on their enhanced physical qualities, assassination skills, and the enhanced physical qualities after blood sacrifice, they can kill everyone in the research institute that is studying the zombie virus, and then use their blood to summon a meteorite to destroy the evidence and incidentally destroy the virus.

This...is a necessary sacrifice!

As for the problems that may arise during the process, that's something that the user-friendly plugin should help take care of.

For example, a user-friendly plugin could implant the code for hacking electronic devices that the other person would need after traveling to the past into their mind. The other person could then solve most problems simply by copying the code.

Even without the blood sacrifice formation, with the code support provided by the user-friendly plugin, although controlling nuclear bombs is basically impossible, controlling the launch of some missiles may not be a problem.

They blew up those virus researchers with missiles!

However, since the best candidate didn't like to use his brain, the proposal was rejected.

"Sir, it seems that a significant portion of these people are strangers." Saeko Busujima looked at the names on the list with some surprise.

Saeko Busujima originally thought that the responsibility of being the savior would likely fall on the main characters, but she didn't see any of their names on the list.

"Who says the protagonist has to be the one to save the world? Besides, the reason the protagonist group is the protagonist group is because they survived the apocalypse, and being able to survive in the apocalypse often means they're not the worst off. In this apocalypse, only those who are most miserable will want to solve the apocalypse," Chen Luo said.

"I see." Saeko Busujima nodded, finding Chen Luo's words to be very reasonable.

Although the main characters may experience many hardships, at least they are still alive.

"Oh, and also, remember to ask them in the order listed, because the higher they are on the list, the less they have to pay to save the world. After the save file is overwritten, all the injuries they sustained while saving the world will become real," Chen Luo reminded Saeko Busujima.

"What about me? Will I go from being an adventurer in the amusement park to an ordinary person?" Saeko Busujima asked.

Saeko Busujima didn't feel any joy about this, because it meant she would have to rejoin Paradise and start accumulating Paradise Coins to strengthen herself again.

"Who knows? That's precisely why I want to save the world and see what happens. But don't worry, your memories will be preserved," Chen Luo said.

Because after saving the world using the third method of salvation, there is an option to retain the memories of the apocalypse, which is equivalent to allowing all those who died in the apocalypse to return to the day before the apocalypse.

The purpose of doing this is to warn people in the world not to make the same mistakes and not to enter the apocalyptic ending for the same reason. Otherwise, wouldn't the world have been saved in vain?

As for whether the puppetization would still be effective after time had passed, Chen Luo was uncertain.

However, Chen Luo is pessimistic about this.

If reshaping the worldline affects people in the future, and they still suffer the same effects when they return to the past, then what's the difference between that and not saving the world at all?

Although both the puppetization ability and achievement level are six stars, the Savior achievement represents the pinnacle of saving the world, so it might have a higher priority...
