The fifth layer did not look like an underground bunker and instead it looked very much like a normal city but just without the sun. It was also a lot less dilapidated than the city which was in the outside world.

Most of the explorers who had come to these ruins were unable to enter the fifth layer and ended their journey on the fourth. That was because there was a mechanical guardian protecting the doors to the fifth layer. That mechanical guardian was made in the shape of a Griffin and it was incredibly strong.

If Elena judged that mechanical guardian according to levels then that guardian's level would be 250 plus. So it was almost impossible to get rid of it without deploying extra large weapons.

But after a lot of experiments and sacrifice the explorers had found a way to distract the mecha Griffin and used that chance to enter the fifth layer. But the cost of items they needed to distract it was very high so not many could use this method.

But Elena did not have to face the mecha Griffin as with the world's will's death this mystical mecha had also died. So she was able to reach the fifth layer easily. Exploring this layer was also way more profitable than the other ones as it had a lot of treasures still left untouched.

But there were also quite a lot of safety mechanisms attached with the treasures. Even though most of them had used the mystical aspect of the science and had become useless, few of them which did not use any mystical aspect were still active and gave Elena a hard time. But still with enough time and intelligence, she was able to collect most of the useful treasures of the fifth layer before leaving it.

...

Again there was a guardian between the fifth and the sixth layers. It was a large mechanical dog with three heads, yes it was a mecha Cerberus. It was slightly stronger than the mecha Griffin but not by much. It had also become useless.

Before entering the ruins Elena had used her powers to give the ruins a power source which in turn activated the normal mechanisms. But the mechanisms needing the power of mystical aspects of science were not activated.

The mystical aspect of science was something unique to this sci-fi world. So even Elena did not have the ability to replicate this function. When the World's Will of MK-1890 died, this aspect also disappeared alongside it. For that reason, those mecha robots were not activated even though Elena wanted to test their powers herself.

But she did not let the mecha robots to go to waste. She collected them and hoped to find a different way to activate them in her mini world. The mecha robots were too cool to just disappear.

So, the sixth layer was also like the fifth one, but the city was a bit more luxurious. The buildings were taller than the fifth layer but the area that the sixth layer occupied was lesser in comparison. But Elena needed almost the same amount of time as the fifth layer to completely search the sixth one.

This layer was the same as the fifth layer as it also had a lot of untouched treasures. Elena was especially astonished to see the amount of gems and jewels this layer had. From that she could guess that the residents living in this layer were specially fond of gems for some reason.

Elena used her abilities to find the reason for that in order to satisfy her curiosity. As this use of her ability did not help her in the exploration, it was not cheating. And the reason was quite simple but hilarious.

One of the most beloved administrators of this layer was very fond of colourful gems and jewels. So, suddenly one rumours spent like wildfire among the residents of the sixth floor that he was going to marry the woman who had the most amount of gems. So, for that reason, all the single and some married women started to collect as many gems as possible due to those rumours. That's why this floor had so many gems.

...

The seventh layer was once again completely different from the previous one. Instead of having large buildings, this whole floor was filled with a lot of well made small villas. This layer had never been conquered before as the guardian to the seventh layer's door was too strong.

The door to the seventh layer was guarded by a mecha Kraken. It had seven long and flexible tentacles like arms that proved too difficult for everyone. Elena once again got her hands on another great mecha specimen.

Even though the area this seventh layer took was smaller compared to the sixth floor and the numbers of people living here was also small but the amount of wealth stored here was insanely high. Not only that but the amount of traps here was also lower.

Probably because the security of this high end layer so very good so most of them did not bother to set up traps to protect their belongings. So, Elena had an easier time looting the treasures here. But unfortunately, most of the items present in this floor used the mystical aspect of science so they got ruined after the world's death.

Still Elena was happy with her gains and she went to the eighth layer with a cheerful mood. The guardian of the door to the eighth layer was a mecha Hydra. Actually it was a Mecha Yamata no Orochi with eight dragon heads and eight tails. It was so cool looking that Elena could not resist the urge and used telekinesis to make the inactive mecha move. It looked super cool.

After she had enough fun with her new mecha toy, she finally entered the eighth layer. There she found a similar layout as the seventh floor but with one eight large mansion instead of several small villas. Those mansions looked majestic and had an ancient vibe to them.

All the mansions had very tight security and the security system not only used the mystical aspect but many measures were also focused on the normal technological approach. So Elena needed a very long time to search all eight of the mansions.

But after Elena was done with the searching she did not leave like the previous time. Instead she stored the whole eighth layer into her inventory. She liked the design of the whole small city too much so instead of just taking the normal loots, she ended up taking the whole floor with her.

She did have to use her powers once more, but she did not use the power for exploration and used it just to satisfy her desires so it was fine in her opinion. It would be too disappointing for such a well made city to get destroyed, that was her thought when she took the whole floor for herself.

...

Finally Elena entered the last and the final layer which was the ninth layer. The guardian of the ninth layer's doors was mecha Narasimha, which had a human-like body but the head of a lion.

It also had 9 hands and all the hands held a different weapon. The left side had four hands and the right side had five. This mecha would have the power of a peak A rank or level 299 if it was active.

This was once more a fascinating mecha robot and Elena took her sweet time enjoying looking at it. She then finally stored it in her inventory and entered the last layer.

This layer only had a single structure present and that was a massive castle. This castle looked majestic and even after millions of years, gave off an intimidating aura.

Elena quickly started to search the castle. This place had more traps than all the traps she had encountered before combined. So Elena needed to spend over two whole months to search the whole place properly.

But the amount of wealth she managed to find was also astonishing. This castle alone had ten times more wealth than all the other layers combined. If Elena just ignored all the layers and came straight here she wouldn't lose out on much.

Elena also found the main thing she was searching for. At a secret chamber in the throne room of the castle, Elena found a young girl's body. She had perished millions of years ago but her body was still in perfect condition.

This person's race was the perfect creation of this world and Elena had planned to use resurrection in her. Most of the souls of this world's inhabitants had disappeared with the death of the world, but the soul of this person was still there in the after realm of this world. Her soul would only disappear when the whole world would vanish, not before that. It was the last struggle of a dead world to preserve its greatest creation.

Elena did not want the hard work of the world to go to waste, so she used resurrection in the Royal Rehona lady. A brilliant golden light surrounded her and disappeared after a few minutes. Then the eyelids of the still body moved a bit and she opened her eyes.
