"Next time, next time for sure," Su Mu said casually.
"Then it's settled!" Senti agreed excitedly.
Su Mu: "…"
Didn't this child realize he was just playing along? Forget it, just treat it like coaxing a kid.
"Oh, little Su Mu is so cute no matter how many times I see it~~" Elysia smiled, stretching out her hand to rub Su Mu's head.
Why did she come here so early in the morning? Was it just to take advantage of Su Mu's form to tease him again?
Su Mu was too lazy to talk or swat her hand away. He had been touched by Elysia countless times—his dignity was long gone, so it didn't bother him anymore.
"So, what do you want with me?" he asked.
"Of course, I came to play with you!" Senti said with a smile. She wanted to spend time with the younger Su Mu while she still could, as such an opportunity might not come again.
"Me too~~" Elysia added, imitating Mou Fei's tone with a flowery smile.
"It's Monday, what's fun about that?" Su Mu grumbled.
"Isn't the fun you?" Unable to contain her joy, Elysia picked Su Mu up and rubbed his soft little face hard.
"I want to too! I want to too!" Seeing Elysia nuzzling Su Mu like a cat, Senti hugged Su Mu from the other side, burying her face into his back.
Su Mu: "..."
No way... why did he feel like he had become a walking mint? Everyone wanted to take a taste, right?
Su Mu spent the whole morning playing along with Senti. After noon, Mobius called him, asking him to come to the lab. His time in this form was almost up, and Mobius wanted to collect more experimental data.
Su Mu agreed. He wasn't sure if there would be any issues when changing back, so it was safer to let Mobius monitor him.
Hearing Su Mu was going to change back, everyone in the Golden Courtyard was curious. Led by Elysia, Vill-V, Einstein, Tesla, Mei, and other scientists couldn't contain their curiosity and followed him to Mobius's lab.
In front of everyone, Su Mu stripped down to his boxers and lay on the experimental table. He protested, but it was useless; he could only endure the embarrassment of being watched.
Soon, Su Mu felt drowsy. He obediently closed his eyes, and when he opened them again, he was back to his original body. Su Mu sighed in relief—thankfully, nothing strange had happened during the transformation.
Moreover, his body was noticeably stronger than before. His muscles were more defined, and even his abdominal muscles were more prominent.
Everyone who witnessed his transformation was shocked. Though they knew Su Mu had been a child, seeing him change was a completely different experience.
"Mobius… you're not just the world's top scientist; you're practically a monster," Mei said excitedly, pushing her glasses up.
For someone like Mei, who was always calm, to get this excited showed how impressive Mobius's experiment was. The thought that such a magical drug was created simply because Mobius wanted to enhance her body was mind-boggling.
Once Mobius confirmed that Su Mu's body showed no adverse reactions, she prepared to continue developing the drug. After all, who wouldn't want to rejuvenate and have an unlimited lifespan?
Mobius certainly did. With infinite time, she could continue her research until she mastered infinite truths. So, although she discovered the drug by accident, she wasn't going to let the opportunity slip away.
Tesla and the others didn't care much for immortality but were still interested in the idea of staying youthful forever. After all, who doesn't want lasting beauty? Even Vill-V felt the same.
In the days that followed, Su Mu became more aware of how powerful his body had become. Before, he could barely keep up with Bronya's demands, but now, he could overpower her easily. She even cried for mercy once and fainted twice.
Su Mu was thrilled. As a man, he could finally stand tall!
Of course, Su Mu hadn't forgotten the promise he made to Bronya. A few days later, he secretly went to Mobius and asked for another shrinking potion, which he gave to Bronya.
Under Su Mu's amazed gaze, Bronya reverted to a younger version of herself.
"This is such a novel experience. I never expected Bronya would change back to her former self," she said, looking at her small hands and slightly bulging chest.
"Bronya, you look so cute," Su Mu said, giving a thumbs-up.
"You think Bronya will be happy if you say that, my perverted darling?" Bronya glanced at him, her tone as familiar as ever.
"Why not?"
"Hmph… You're right. Bronya is happy," she said, the corners of her mouth lifting in a slight arc.
Then, in front of Su Mu, she put on her old school uniform from St. Freya Academy. Su Mu had wanted to see her wear the Herrscher of Reason's outfit, but he hadn't asked Eden to make one before.
Now, it was impossible. If Eden found out he was using her creations for this… even her good temper wouldn't save him.
"Bronya, let me hug you," Su Mu said, opening his arms.
Without hesitation, Bronya jumped into his embrace. The height difference between them was now very apparent—Bronya barely reached Su Mu's chest. Su Mu, standing at 1.8 meters, had grown two centimeters taller due to the potion, while Bronya was now only 147 centimeters. The difference was more than 30 centimeters.
Holding her petite body, feeling the different sensation, Su Mu felt like his life was complete. *People live just for Bronya.*
"How does it feel? Are you happy, Brother Su Mu?" Bronya asked, looking up at him expressionlessly.
"Hiss—Bronya, you're too good at this…"
Su Mu was stunned by the power of her words.
Bronya, feeling content in his arms, suddenly remembered something and pushed him away, running into the bathroom. Su Mu was confused.
A few minutes later, Bronya staggered out, looking as if something had hit her hard.
"What's wrong, Bronya?" Su Mu asked, worried.
"It's grown… that thing has grown back…" Bronya said, with an expression torn between laughter and tears.
"What the hell?! No way!" Su Mu glanced at her lower body and understood immediately. He was shocked, but it made sense. The potion had regressed her body by ten years, bringing everything back to how it was then.
Bronya, looking terrified, realized her current form was much weaker. If Su Mu got serious, she might not survive…
"…"
The two sat in silence for a long time.
After processing everything, Su Mu decided, "Maybe we should call it off for tonight. I'm just happy to be able to hold you like this."
"...No," Bronya suddenly said, determination burning in her eyes. "Bronya will not give up! No matter how tough it gets, I will try!"
Su Mu was speechless. Why was she getting fired up over this?
"Come on, Amu. Bronya will not lose." She took his hand and led him upstairs.
Su Mu: "…"
That night, Bronya braved through it all. The rest of the details were, of course, not for outsiders.
After that night, they discovered a new way to play, and every few weeks, Su Mu would ask Mobius for more potion. Sometimes he'd drink it, sometimes Bronya would. It became their little routine.
Su Mu even asked Mobius to improve the potion so it would only last eight hours—perfect for nighttime use, without affecting daily life!
Mobius, upon learning what Su Mu was doing with the potion, was disgusted but continued providing it. After all, her pride as a scientist didn't allow her to turn down such an unusual request.
As Su Mu's days passed in bliss, a new update for *Honkai Impact 3* arrived.
In the version preview, Su Mu introduced the new content to the players. Alongside the usual main plot updates in Chapter 24 and new stages, the event "Maze and Rabbit" drew attention. Players were captivated by the cyberpunk-like setting of Skydome City, the stylish Brownie character, and the armored Yae Sakura.
The next day, when Elysia's live broadcast started, countless players tuned in. This time, she was joined by Tesla and Dr. Einstein.
"Hi~~ Did you miss me?" Elysia greeted the audience as usual before turning to Su Mu. "My dear Su Mu, I think many players are curious. What's the relationship between Brownie and Bronya in the event story? Are they from different worlds, or is it a relationship like Stargazer and Theresa?"
Su Mu smiled. "It'll be clear once you play through the story, but I don't mind telling you. Brownie is actually Bronya's nickname. Since she exists in a world bubble, she doesn't have the Reloaded Bunny, so I incorporated rabbit elements into her design, making her a mix of both Bronya and a bunny character.
