"The default initial Hertz is 0."
"The correct sound frequency to pass this level should be based on 0 Hertz. It needs to be increased 9 tis consecutively, then decreased 2 tis. The only issue now is how much to increase and decrease."
"Are there any other anomalies?"
"None." In the train room, Ai’s voice paused before speaking again, "I didn’t find any special anomalies."
"Let take a look!"
Chen Mang took a deep breath, jumped off the train briskly, and headed towards the stone slab at the front of the square. He needed to see if the final answer was hidden on that slab.
A very rudintary stone slab.
Engraved on it were the three sentences he just saw. He carefully counted each word, perhaps the numbers to add were the sum of these words. But in the next mont, he was slightly stunned, every corner of the square had been thoroughly searched, and this stone slab had been visited by Li Shiji countless tis.
But it seems, there is a place that hasn’t been walked upon.
And that is...
Chen Mang looked at the Constant Star Train, and that place is under the train carriage. He imdiately used his cane to remotely control the train to hover in the air and walked towards the underside of the train.
Sure enough—
At the very edge of entering the square, under the 14th carriage, he found so extrely faint and blurry numbers engraved on the ground.
"1892".
"Got it!"
Chen Mang grinned. If he’s not mistaken, the answer can only be two things: one possibility is 1892 Hertz, the other is starting from zero, add 1892 nine tis consecutively, then subtract it 3 tis.
That is 11352 Hertz.
"Everyone, quickly and orderly return to the train!"
His voice quickly spread across the square through the Car Sound System, then he walked briskly towards the train room, sat in the seat, and excitedly took a bottle of mineral water handed over by Fang and drank it all before looking at the screen.
"Ai, emit the sound of 11352 Hertz."
"Give it a try."
"No problem."
In the next instant—
Accompanied by a piercing sound that ca from the Car Sound System, the howling expressions of tens of thousands of faces on the surrounding walls instantly ceased. The originally hideous expressions gradually cald down, with eyes closed, as if asleep.
Imdiately after!
"Click, click, click!"
The sound of gears turning was heard, and the walls that were like a cage slowly split from the middle, revealing a Train Tunnel wide enough for the Constant Star Train to enter.
"What a pity."
Chen Mang looked at the train tunnel in front of him with a little regret. Unfortunately, the final answer was 11352 Hertz. If it were above 20000 Hertz, it would have been great, as only by upgrading "Car Sound System" to above Level 10 could one have the Supermodel Effect that can emit sounds above 20000 Hertz.
Other trains definitely don’t have this effect.
He could have used this thod to eliminate almost all of the other 19 trains here.
He wondered how the other trains were progressing.
This level wasted more than half an hour of his ti, he needed to speed up the pace.
He slowly pushed the control lever, and the train entered what seed to be the underground "Train Tunnel." The path ahead was unknown, but having passed two levels in quick succession, he felt a bit confident. Even if the next level increased in difficulty, he would no longer feel utterly helpless.
The answer must exist.
Once this condition is t, the rest is simply a matter of ti.
"Master Mang."
Standing beside him, Li Shiji apologized, "I’m sorry, I didn’t help much..."
"It’s okay."
Chen Mang waved his hand and softly said, "In these circumstances where data is quickly inputted and filtered, human labor could never compare to AI. There wasn’t much room for you to play a role in this level, so don’t bla yourself."
"I think we did pretty well in the first two levels, we should still be able to break into the top three."
"Keep it up, stay energized."
...
The Train Tunnel wasn’t too short, and the Constant Star’s speed wasn’t too fast either. After traveling at 500km/h for three minutes, they reached the location of this level.
The space in front gradually opened up.
Upon exiting the Train Tunnel, what ca into view was a massive "Heavy Machinery Factory" located in the square in front of the factory’s entrance.
The steel doors were full of rust and were crumbling down to the side.
Weeds grew around the tilted cranes.
The ground was covered in a liquid mixture of engine oil and sticky blood, making the whole scene look dilapidated. In the corners of the factory, one could vaguely see a small mountain made of chanical debris and human bones, slightly higher than a two-ter wall.
The train slowly ca to a halt.
A light screen appeared before them.
-
"Congratulations, Pioneer, reaching here is already proof of your strength."
"But—"
"The train is a team effort. If only the Train Captain is exerting effort, this train won’t have much potential. Talent storage is an anti-human task in Doomsday, but it’s sothing that has to be done."
"The next part will be a lot of fun."
"You may choose to exit this Adventure Map at any ti, but please note that choosing to give up ans you will voluntarily and permanently opt out of the ’chanical Civilization Heir’ selection."
"This level is the final level of Stage 2. Successfully passing this level ans clearing Stage 2."
"Following this, a thousand zombies will attack you, each wave lasting fifteen minutes. After each wave of the Corpse Tide finishes attacking, your train will have five minutes for rest."
