A Foggy City Holiday? Wishful Thinking!

P. S.: "Fullbottles" and "energy bottle" are both acceptable terms. The sound effects for Build will primarily be a mix of Chinese and English; let's remove the Japanese. After all, Tesla isn't Japanese, and we can't use Japanese for sound effects.

"In short, I've gotten myself into a sudden incident. That's it. I'll have to ask you to cover for Kiana and the others, Mom."

He had initially thought it would be difficult to say those two words, but after deeply experiencing Theresa's sincere feelings, he naturally uttered the name.

"Hey, wait a minute, Sachi, what happened? You're not in danger again, are you? If you need my help, the Far East Branch's resources are at your disposal!"

"Don't worry, you know my strength, and Judah is with me. He's almost fully recovered and will be fine."

"Why can't you stay still, kid..." Theresa was having a headache with her son.

Fortunately, he hung up the phone, picked up the coffee on the table and took a small sip. Einstein across from him ordered a dessert, ignoring the sullen red-haired Lobster Girl next to him.

"Bird's Nest Head, what do you mean?"

"Dr. Tesla, you are well past the age of enjoying sweets. I don't think this kind of food for children is suitable for you."

Tesla pointed to the cake in front of her. "So what are you doing?"

Einstein, shameless as ever, said, "To replenish sugar."

Fortunately, she ignored the daily bickering between the two rivals, quietly ate her cake, and casually fed Little Xuan a spoonful.

Without a digestive system, Little Te could only squat under the table, but she didn't care. In her opinion, Little Xuan's behavior of taking in extra energy was simply foolish. As a high-level Armed Doll, she only needed to recharge and didn't need such meaningless functions.

On the transport ship bound for London—

Fortunately, she had dozed off, and her two fox ears drooped down. "So what do you want that you called me over in the middle of the night?"

Little Xuan lay on his head, trying to tie a knot in the two fox ears, but after being rewarded with a flick on the forehead, he turned his attention to his tail.

Tesla examined his tail and ears. "Before that, explain to me what's going on with you. Didn't you only have fox ears before? How come you've grown a tail too? Are you going to turn into a fox in a while?"

"Um, the power of the Stigmata has gotten a little stronger recently. (It's probably because my Polymerization with Sakura has deepened, so the speed type has also changed a bit. Speaking of which, it feels so good to grow up.)"

"Is that so? Even its size has increased? Tch, it looks pretty good. Here, take this, it's Fullbottles I extracted from Titan." Tesla pulled out a black Fullbottles and tossed it to him.

Growing up this way is a good thing for him, since his mother's body has remained at the 12-year-old level due to the Polymerization of Honkai Beast genes, and he seems to have inherited this trait. Based on his physical examination since entering school, his body has not shown any significant growth in the past year.

Robot!

"Based on my analysis, it should be the best match for the Phoenix Energy Bottle you obtained earlier. Make good use of it. Oh, right, there's something I forgot to tell you before. The Lock Energy Bottle you obtained from Judah has an extremely strong weakening effect on Honkai Energy. If you use it in combination with other bottles, your combat power will probably be greatly reduced. I suggest using it only with the Drill Crusher to unleash skills. That's the best choice."

Tesla couldn't help but glance at him a few more times. He had to admit that the little guy was really good-looking and pleasing to the eye. He was rich, kind, and generous, but he was a bit of a show-off, a bad habit inherited from the Kaslana Family that he just couldn't shake.

For some reason, she really wanted to touch his ears and tail; just imagining the Jotaro feel made her excited.

Feeling Tesla's intense gaze, Xing couldn't help but shiver and quickly asked, "So what is it?"

"To be honest, I don't know either. Bird's Nest Head called me urgently just now. I didn't want to answer, but she kept calling several times, keeping me awake. She said she's in London and in unprecedented danger, and asked me to bring my Kamen Rider to rescue her. That sleep-depriving bastard, if nothing really happens, I'll kill her!"

Although Tesla was sharp-tongued, it was clear that his red eyes were filled with worry.

Little Xuan, tired from being stroked by his tail, lay listlessly in his arms and yawned. "Young hero, it's so late and you're still on a business trip. You must be exhausted. And when is my immortal coming back? You said she's been gone for almost half a month. That wretched Otto, how dare he exploit my immortal like this! Don't let me run into you!"

Upon hearing Little Xuan's words, Tesla turned his head in surprise. "You little rascal, do you have a grudge against Otto?"

"That bastard... ugh ugh ugh!"

Just as Little Xuan was about to recount Otto's atrocities, Xing covered her mouth, saying, "You can't just tell everyone, you little darling!"

Tesla looked suspiciously at Xing, who was covered in cold sweat. Xing racked his brains and made up an excuse, managing to fool him with a combination of coaxing and deception.

After landing at the Anti-Entropy base in the UK, the two rushed to the location designated by Einstein, where they encountered a leisurely blue-haired woman in a private room of a London café.

Tesla, who was initially worried about his girlfriend, suddenly exploded. "Bird's Nest Head, you call this being in danger? Believe me or not, I'll punch your head off!"

"Dr. Tesla, don't be fooled by appearances. Don't be fooled by my calm and cheerful demeanor; I'm actually very anxious inside. By the way, who's that good-looking guy next to you? Some poor soul who was just tricked into working here?"

Enraged, Tesla reached out to the boy. "Xing, give me the Gorilla Fullbottles and the tank -Fullbottles. I want her to experience the power of science firsthand!"

Fortunately, Tesla desperately pulled back from taking Einstein down with him. "Don't be impulsive, Doctor! This is a public place, you can't do anything rash!"

Einstein looked at him with surprise. "You are Xing? Little guy, did you accidentally ingest Dr. Tesla's useless invention and develop prematurely? Have you had a physical examination? There might be some side effects. Look, the color of your hair and eyes has changed."

Her words only fueled Tesla's anger. "**(Anti-Entropy profanity), what do you mean by useless invention? Don't hold me back, I'm not Tesla if I don't tear that infuriating mouth of hers apart today!"

Faced with the bristling Lobster Girl, Einstein waved to them, signaling them to sit down and have something to eat.

Let's go back to the present—

Tesla, trying to calm herself down, gulped down a large mouthful of coffee. The bitter taste almost made her faint from crying, "Damn it, I was so angry, I forgot to put sugar in!"

Fortunately, Tesla thoughtfully ordered her a pudding, and Tesla gave a soft hum and started eating.

Einstein squinted at the two of them, as if observing, or perhaps lost in thought. After Little Xuan finished her fifth cake, she asked, "Xing, how is Dr. Tesla's work on the Fire Moth?"

"Well, generally speaking, the professor is sloppy and unkempt. She always goes to the wrong class, and she even berates students when they don't understand. She never considers whether it's her fault, and she always misappropriates funds to create a bunch of non-existent inventions... There are too many faults for me to remember."

Einstein agreed wholeheartedly, saying, "That's absolutely right. Look, Dr. Tesla, I never imagined that besides Yang and me, there would be anyone else who would tolerate your many shortcomings and fund your experimental research. Be grateful."

Sensing Tesla's resentful gaze, Xing added without changing her expression, "However, the doctor is serious and meticulous, always focused and attentive when working. She is never late for class, always starts on time, and never goes over time. Although she never scolds people, she always considers the feelings of others, making her a very good teacher and friend."

"That's a very good assessment. Yang is truly fortunate to have a student like you." Einstein nodded in satisfaction, his appreciation for Yang's good fortune growing even stronger.

Let's examine him a bit more. Whether he's qualified to inherit the core of the Herrscher of Reason requires further observation from multiple perspectives.

Tesla turned its head away Tsundere and snorted again.

"So, Doctor, you didn't call us here just for coffee and dessert, did you? Shouldn't you tell us the truth?"

At this point, Einstein paused, remained silent for a while, and then slowly pulled up his sleeve, revealing a patch of illusory purple where the human body should have been.

"As you can see, there is a problem with a part of my body."

Tesla and Yuki exclaimed almost simultaneously, "Quantumization?!"

"The little guy is doing well in his studies; he knows quite a lot."

Tesla quickly grabbed Einstein and began to search her body, fearing that she would disappear from his sight at any moment.

Einstein shoved Tesla away with disdain. "Don't worry, Dr. Tesla, only a part of my body has uncontrollably turned into Quantum State, it's not that serious yet."

Tesla asked anxiously, "What exactly happened? Explain yourself!"

Einstein remained completely calm and even gave Xing a science lesson. "Actually, before this, we at Anti-Entropy had already made some progress in the quantum field, and were able to quantize the Titan Mech to achieve a surprise attack effect. We have even made some progress in the quantization of the human body, but the situation I am facing now is much more complicated."

"What we study is controllable quantization, but the quantization within me is not within our control. I don't know when it will worsen and cause me to completely disappear from the real world. However, it seems that as long as someone can observe me, this state will be somewhat alleviated. Look."

Einstein raised his left hand, and the illusory part slowly returned to normal.

"As for why I became like this, it all started a few days ago. I received intelligence that there might be clues to the Second Divine Key hidden in London. Unsure of the credibility of the information, I came here alone. I didn't expect that instead of finding the Second Divine Key, I would encounter a mysterious girl."

Hearing this, the two became more attentive. "A girl?"

"Yes, it was a dark night. I was walking back to the hotel after leaving the museum. I felt someone was following me. I initially thought it was some blind pervert, but unexpectedly, after I deliberately walked into a dead-end alley, I saw a graceful young woman."

"Because the light was dim at the time, I couldn't see her face clearly. Her features were long hair, about 1.5 meters tall, wearing a crystal pendant and a specially made dress. What impressed me most were her eyes, which shone with a soul-devouring red light even in the dim environment."

"There seemed to be a terrifying aura around her. I was stunned and unable to move until she walked up to me and grabbed my arm. Only then did I barely regain control of my body and summon the Titans who were with me to fight her."

"She didn't take me seriously. When she saw the Titan Mech, she released me, took out a large scythe from somewhere, and with just a light swing, cleaved a Titan into pieces—even though it wasn't a very powerful model."

"I was terrified at the time. While the mech was holding her back, I took off running and ran until I was far away. When I came to my senses, I found that my body was soaked in cold sweat. Moreover, the places she touched showed quantum symptoms."

"Yang has gone missing in Sea Abyss City. I don't know the specific reason, but right now, I need to take care of my own problems first. If Yang is really in danger that he can't handle, then there's nothing we can do..."

It wasn't selfishness; Einstein was simply acting with rational thinking.

Tesla bit his lip, his body trembling slightly. "Why didn't you tell me about Yang's disappearance in the previous call?"

"Given your personality, if I told you directly, you would most likely go and die."

"Slap!" Einstein received a solid punch from Tesla, who was filled with rage, right across the face.

Tesla was practically screaming, "Now, what do we do?!"

"Shenzhou's an old Chinese saying: 'The one who tied the knot must untie it.' As it stands, only by finding that girl and defeating her can I have any hope of recovery."

She looked at Sachi, who was looking down as if deep in thought, and said, "I know this might sound selfish and unreasonable, but I need your help, Sachi Kaslana."

"No problem. I swear on Kaslana's honor, I will defeat her." Without any hesitation, Yu agreed.

Tesla smacked him hard. "Are you stupid? Didn't you hear what Bird's Nest Head said? If she touches you, you'll be forced into uncontrollable quantumization. What if you get caught in it too?"

He grasped her left hand, which was covered by an iron fist, adjusted his hat, and said in a relaxed tone, "Don't worry, I'm very strong."

"But..."

"There's nothing to worry about. Once I transform, she won't be able to touch me directly anymore, right? What's there to be afraid of?"

Einstein nodded and said, "That's right, that's one of the reasons I called him over."

Tesla was dumbfounded. Damn, how come they didn't think of this?

As she looked at Einstein's illusory arm, it seemed to be talking to itself. "My philosophy is to fight for all the good things in the world, and of course, the kind-hearted scientist who tirelessly fights against the Honkai is among them."

Furthermore, the girl Einstein described looked so much like "her" that he was determined to find out more.

Einstein suddenly remembered something. "Oh, right, there's something I forgot to tell you. When I was looking for clues here earlier, I think I saw Otto..."

Xing instantly lost her composure. "What did you say?!"

——Divider——

The girl with red eyes sat on the huge engine of the train, looking down at the pendant on her chest, her silver teeth clenched.

"Seele ..."

Author's Note—

Tesla belongs to Old Yang, don't overthink it. Besides becoming a wife, a girl can also be a friend.

Even Einstein didn't have it, and don't overthink it.
