Came to the drained riverbed, where there was a huge stone gate.

Sliding down the riverbank, Otto slowly walked to the stone gate.

It's a solemn and eerie door. On the moss-covered prototype door panel, a line of quaint and strange engraved handwriting is faintly visible.

????????????????

“eba dagami rashi ha nu”

"For the next generation...... War...... By us? …… We fight for the future. ”

Sure enough, this is something left over from the last century

Sighing inwardly, Otto instructed the surrounding Destiny personnel to lift the stone gate with a crane.

The structure of the ruins itself is reminiscent of the ancient castle of Petra in geographical miscellaneous matters, or Tolkien's dwarven city.

In the huge underground castle, the rooms are dotted with walls, and the plastic-like white façade makes people think that this may be a secret base for aliens.

The ground under the feet is also made of a considerable amount of masonry, but it is badly damaged compared to the rest of the crypt.

Touching a pillar in the crypt, Otto looked up at the structure.

It stands to reason that the structure here should be sturdy and free from any risk of falling rocks

"So these ruins and ruins at the end,"

"It was sabotage, huh?"

Taken aback by his own speculation, it means that someone found out about this place before the Mandate of Heaven.

"Huh? Sound! ”

Holding his breath, Otto carefully discerned the sounds that were spreading in the air.

Because he came down alone, he couldn't ask about other people's perceptions.

But even if someone else was there, they might not be able to hear it.

The normal hearing frequency range of a normal person is 20-20,000 Hz, and this range will gradually decrease with age.

At present, this mosquito sound has reached the point where adults cannot detect it.

As for Otto, he is no longer among those who are beyond the realm of humanity.

Guided by Superman's hearing, Otto easily found the source of the sound.

Along the way, there were those inexplicable pre-civilization devices, and there were also many relatively close remnants - white bones that had not yet flourished, and early rifles. Or even some Shoshone tents.

Even the most mentally handicapped person can easily see that the history of these things will never exceed 200 years.

……

At this moment, in front of Otto's eyes was a gate made of alloy.

"Is it locked?"

Seeing the keyhole on the door, Otto found that it could not be opened after trying the consequences.

He pulled out the pistol he had with him, and aimed the slender silver-white body at the keyhole.

With a "bang", the alloy door finally opened.

The inside of the door was a very clean room, at least compared to the outside. The surrounding plastic-like wallpaper has been heavily liquefied.

On the ground, there was a badly faded feather shawl.

Walking forward, Otto lifted it up.

"Dry corpses? Looking at the powdery surface, it must have been at least 10,000 years old. ”

Silently walked to the desk in the center of the room, and on the dusty table was a strange machine, from which the noisy sound came from.

"What is this thing, Ultrasonic Soul Steel Recorder? Why did it appear in this place. ”

Looking around, Otto saw a text carved out of a candle at the top of the room.

Boys who have come here......

I've entrusted you with the last soul steel......

The Knight of the Virgin City, by H. Lentinion A

"Soul steel? Londonderry, Northern Ireland ......"

Reading the underlying content of the words, Otto planned to find a time to take a look.

Lentinion is the old name of London in ancient Roman history, and the city name includes the places of London, and only Londonderry is called the "virgin city". Because it has never been conquered in history.

Out of the room, Otto was going back.

But at this moment, as if a burst of electricity passed through his body, Otto slammed into a spirit.

With wide eyes, he looked at the wall to the side.

With the sound of "boom, boom", a secret passage opened here.

"Wait, what's going on, did I trigger some trap just now?"

Otto thought to himself, there was nothing unusual about it except that he had just felt electrocuted, and that feeling was more like an instinctive reaction to the danger of a creature.

Shaking the flashlight in his hand, Otto still planned to go down and take a look.

The dark staircase did not put any psychological pressure on him, and along the wet walls, Otto finally came to an empty room.

"Hmm~"

Covering his nose, there was a strange smell in the place. It's like the taste of your own lab.

"This, yes...... No way. ”

Scanning the flashlight in his hand, Otto found the broken culture tank on the side.

The debris fell to the ground, but it was still recognizable.

"The laboratory of the last century."

His hands were shaking with excitement, and Otto's tone was a little shaky.

Along the way, both sides of the road were always filled with culture tanks, some of which were even alive......

As he went deeper and deeper into the underground lair, Otto finally saw the original owner of the laboratory.

The clothes on his body had completely rotted and disintegrated, and only the dry corpse had fallen to the ground in a strange bend.

The heavily weathered corpse was no longer recognizable, and Otto walked over to the stone table in front of the corpse.

On it, there is a large string of dense ghost drawings.

Combined with the corpse's strange posture, it can be deduced that it may have been recording something at the time of its death.

"In order to fight the more and more evolved lawyers, humans have begun to study their secrets"

Translating the words on the stone table, Otto read so-so with his own understanding.

"Humans have created 13 powerful 'weapons' by defeating the 'core fragments' left over from the lawgiver and sealing them in the 'soul steel' composed of nanomachines."

"Weapons? Is it referring to holy relics? ”

"Relying on 13 weapons, humanity has gradually gained an advantage in the war against Honkai"

"However, all this collapsed in the face of the great power of the 'Last Lawgiver'"

"I'm not willing to give up, I know that the next civilization will also face collapse"

"I have put all my life's learning into the genetic factors of human beings, and when these recessive genetic factors manifest themselves in the next generation of humans, they will emerge as 'stigmata'!"

"These girls with genetic factors are protected in hundreds of safe cabins, waiting for their awakening in tens of thousands of years."

"The name is...... MEI?！ Mei Yi ?!! ”

Slowly comprehending the last sentence, Otto's eyes were covered with a faint blue mist.

"Hahahaha"

Covering his forehead, Otto couldn't resist the urge to laugh out loud.

"Calm down, don't get excited too soon."

After convincing myself to calm down my excitement, the next thing I thought about was how to transport these things back.
