"Tsk! What's wrong? Won't you let others speak?" Tesla scratched her neck.
"Allowed, of course," Nancy Edison nodded with a smile. "But for a loser who doesn't want to speak kindly, it should be good to suffer a little, don't you think?"
"Who are you calling a loser?" This time, Edison didn't answer, but just curled her lips and made a greeting gesture.
As the current Leader of the North American branch, Edison was always guarded by a group of bodyguards in suits.
"What, what do you want to do?" Tesla's tone began to tremble as she watched the team of bodyguards gradually move behind Edison.
"Well... what do you think I want to do?" Edison tilted her head innocently. The group of bodyguards behind her was still full of oppression.
"I warn you, this is broad daylight!" Tesla looked at Edison, who was pretending to be innocent in front of her, and instantly became timid. She began to slowly retreat, as if ready to flee at any moment.
Edison suddenly laughed, "I've wanted to say this for a long time... Your reaction is really interesting, Dr. Loser."
"You're the loser!" After realizing that the other party was playing with her, Tesla glared angrily at Edison, who had lost her composure and was laughing. But looking at the big men in suits and leather shoes behind Edison. Well, let her win this round for now.
"By the way, Dr. Einstein, this is a gift from the meeting. Please accept it." Edison gestured with her hand, and a bodyguard behind her respectfully handed a suitcase to Einstein.
"The gift I promised you before, but it was stuck due to various factors, such as materials when I was in London, so I've only made it now."
Gift? Bewildered, Einstein opened the suitcase: there was a screen inside. This is a gift for Tian Shi. Einstein quickly realized this, silently closed the suitcase, and nodded.
"I have received Ms. Nancy's wishes."
"..." Edison tilted her head and looked at Einstein, with the words "This is not what I want to hear" written all over her face.
"Tonight, Ms. Nancy, please join us for dinner." Einstein reluctantly changed her words. What's after dinner? I'm afraid she's just preparing to live with Tian Shi at night, right?
"I can't help it. I'm a bit guilty. After all, I'm eating soft rice. It doesn't matter if I sell my body." Tian Shi sighed beside him. Einstein rolled her eyes slightly at the source of the sound. Suffer? I'm too lazy to expose you.
"Then, the ruins below will be handed over to you." Edison, who got the answer she wanted, left happily.
"That is..." Welt was still a little confused about this series of events.
"Just a local tyrant." Tesla sneered, "Let's go see what's buried here."
Everyone took the open-top elevator all the way down, and soon they saw a solemn and heavy metal door at the bottom, with simple and strange text clearly visible.
"We are fighting for the future."
"We... the next generation... for... that should mean 'we fight for the future'." After Tian Shi directly said the text above, Finn also translated it. Einstein looked at the air in surprise, as if surprised that Tian Shi knew the words of the pre-civilization.
"I never said I didn't understand pre-civilization writing." Tian Shi noticed Einstein's gaze and explained softly. He didn't study systematically, but he lived with Aponia and Mobius in the pre-civilization for nearly 20 years.
Although he didn't dare say his language level was very high, he had no problem reading and writing pre-civilization text.
"..." Suddenly I felt that Finn was useless. Compared to Einstein, who only thought about it, Tesla really gave Finn a strange look.
Strictly speaking, this guy is really annoying, he's next to them, and it's not easy for them to communicate directly with Tian Shi like in Laboratory 42. If they had known that Tian Shi knew the writings of the pre-civilization, they wouldn't have brought Finn here.
Einstein tugged at the corner of her teacher's clothes. "Tian Shi knows."
"He knows?"
"What's wrong?" Finn looked at the teacher and apprentice whispering behind him with some doubts.
"It's nothing, let's go in." Planck opened the door, and an ancient ruin resembling a city appeared in front of everyone.
"It's like a dwarf city from Tolkien's novels." Looking at the shocking ancient ruins underground, Tesla sighed sincerely. The scattered remains of rooms and the extremely industrialized metal plank roads seemed to speak to them of the glory of the pre-civilization.
"Look, look! Isn't this the 'M-theory' you studied before?" Finn found a dilapidated blackboard among the ruins.
The girls silently distanced themselves from the excited Finn, but Tian Shi noted that part of the formula with great interest. Very little, and nothing can be researched. This M must refer to Dr. Mei.
On the other side, Einstein stopped Schrödinger.
"This place is really very solid, isn't it?" Einstein's flashlight swept across the top of the cave, and she could vaguely see that the imperceptible supports had merged with the stalactites, but they didn't seem to be damaged at all. Obviously, this is not a masterpiece of modern people.
"Yes, the support structure is intact, which is incredible, but there is no risk of rockfall."
"Then here..." Einstein looked at the ruins around her. "Foreign enemy invasion? Infectious disease? Internal strife?"
Just after expressing her doubts, Einstein suddenly closed her eyes uncomfortably and put her index finger in front of her lips.
"Do you hear... a sound?"
"..."
"No."
"No sound is heard except Finn's shouting." Schrödinger, Tesla, and Planck shook their heads.
Einstein still didn't open her eyes, only frowned.
"Didn't you hear it? It was sharp, like tinnitus[1]." Einstein put her finger in her ear, twisted it, and pulled it out sharply.
"It's not an illusion!"
"Mosquito noise?" Planck murmured softly. "Lieserl, can you identify the source of the sound?" Tinnitus sound, in short, is a kind of ultrasonic wave that only minors can hear, most of which comes from some kind of facility that is still in operation.
Of all the people present, only 17-year-old Einstein was a minor. Einstein completely closed her eyes and felt the mosquito noise in her ears, and let Tesla help her forward.
Everyone had a hunch that the source of the sound... might be the biggest secret of this relic.
[1] Tinnitus, also known as tinnitus, is the perception of a sound, such as a ringing or buzzing, that has no external source.
