And what he was worried about just now was not the question of whether he could go back or not.

But another thing that is more important to him.

That is-the perfect clearance of the copy.

His goal from the beginning was to pass all the dungeons perfectly.

It's not an obsession with scoring.

It's simply because only he knows the secret-if you pass the dungeon perfectly with the SSS rating, you will get the opportunity to extract the dungeon as the exclusive world authority!

This is a reward that he absolutely cannot defend!

Even surpass any other rewards in the SSS level clearance evaluation!

But this copy.

At present, there is only one task with the upper limit of S level.

Obviously he has basically cleared the level, what about the remaining tasks? soft.

Chapter 600 The Root of the Disaster, 300-member Committee (5/5, subscription required)

Want to complete the copy perfectly.

It is necessary to complete three important tasks and achieve a perfect evaluation of the S level.

In the end, when the dungeon was cleared and settled, three S-level tasks were perfectly completed to obtain the highest SSS-level clearance evaluation.

However, Su Yue had only one mission of "Saving Destiny Girl".

The other two have not been seen.

Although the old cat also had an S-level mission he didn't know about.

But that is the exclusive task of the villain.

Belongs to the evil road line.

There is a certain conflict with Su Yue's mission.

So this is not actually a required task.

In fact, he already knew one of the remaining two tasks.

After all, he can almost guess the possible setting of some tasks as long as he follows the original route of the work "Stone of Destiny".

Saving several important girls is indeed an important thread.

But for the many tragedies and troubles in "The Gate of Destiny", it even easily caused the real reason for the future despair and the ending of the world war.

It is [Time Machine].

For this era, the time machine is basically the fire of struggle.

It is an existence that cannot exist in this world.

880 So there is no time machine on the last perfect world online.

So according to Su Yue's speculation.

Another important task is to be completed after reaching the perfect world line-destroy the time machine!

This is also the main task of the protagonists in the original work.

The time machine that will bring struggle and misfortune, which is now beyond human control, is strangled in the bud.

Don't let it be born in this world.

Only in this way can this world have a bright future.

Su Yue is very sure about his own speculation.

So come this way.

Only the last task is left.

What could this task be?

Su Yue thought about many possibilities.

Many of them are unable to rise to the main line, at most they can only be regarded as side-line tasks.

He might do those tasks if he has time and interest.

But those are obviously not the main line of this copy.

The first task is to save the girls.

The second task is to eliminate the important props that cause chaos.

Then the third task...

"Destroy... the evil party?"

Su Yue suddenly realized that he seemed to have grasped an important clue.

That's right.

He suddenly remembered.

There is an existence that runs through the main line of this world from beginning to end.

That is SERN!

It is true that SERN's existence seems to be hidden in some worlds.

But they have always existed.

And-the study of time machines has always been their main topic!

Even if it is heading to the final perfect world line.

Their research on the time machine will not stop there.

Even if he and Makise Kurisu don't develop a time machine, SERN should still succeed in researching it one day.

Although by that time, perhaps hundreds of years later, humans at that time might no longer have to fear the existence of time machines.

But who is right about everything?
