Brother, just how powerful is our family?

January 19, Bishui Huating Villa District, Huai County.

Three black cars drove into the parking space of the Qin family villa.

The rear door of the middle Maybach opened, and Qin Yang jumped out, dressed in trendy clothes, wearing sunglasses, and the Richard Miller watch on his wrist gleaming in the winter sun.

"Brother, what's the rush? I'm surfing with my friends in Sanya." He took off his sunglasses, a smile on his face.

Having spent the last few months traveling and enjoying himself, Qin Yang exudes confidence and a relaxed demeanor, a quality bestowed upon him by wealth and freedom.

Qin Feng stood at the villa entrance, dressed in simple home clothes: "Come in and we'll talk."

In the living room, Qin Yao's parents and Qin Yao were already waiting.

Qin Jianguo and his wife sat on the sofa and smiled when they saw their youngest son return.

Qin Yao, dressed in fluffy loungewear, was scrolling through short videos on her tablet.

"Everyone's here." Qin Feng gestured for everyone to sit down, then looked at Qin Yang, "Did you have fun?"

"So happy! I'm so happy!" Qin Yang exclaimed, beaming. "Brother, you wouldn't believe it, the owner of that yacht club in Sanya recognized me and insisted on giving me a yacht. I said I didn't need it, but he kept trying to get close to me..."

"Alright," Qin Feng interrupted him, "I called you back because it's important."

Qin Feng clapped his hands.

Four composed bio-engineered medical personnel, dressed in white medical uniforms, emerged from the side hall, each carrying a silver metal box.

Qin Yao curiously peeked out: "Brother, what's this?"

Qin Feng didn't answer directly, but looked at his parents: "Dad, Mom, do you remember I told you before that I did some... special scientific research in Africa?"

Qin Jianguo nodded: "I remember. We don't know anything about it, but you know how to handle things."

"What we need to do today is one of the results." Qin Feng opened a box containing five transparent syringes filled with a pale golden liquid that shimmered slightly under the light. "This is called gene optimization fluid."

"Gene optimization fluid?" Qin Yang's eyes lit up. "Is it the kind from novels? The kind that turns you into a superhero after an injection?"

Qin Feng nodded: "Similar, but more complete and safer."

Qin Yao put down the tablet and leaned closer to look: "Brother, don't tell me... you really have a system or something?"

Qin Feng chuckled and gently patted his sister's head: "What are you thinking about? Reading too many science fiction novels?"

"But this is too sci-fi..." Qin Yao muttered.

Qin Feng said seriously, "Simply put, this is a biological agent based on gene editing and nanotechnology. It can repair human defects, optimize gene sequences, and stimulate potential at the molecular level."

He picked up a syringe: "The first injection is mainly to optimize physical fitness. After completion, various indicators such as strength, speed, endurance, and recovery ability can reach more than ten times the human limit."

"Ten times?!" Qin Yang exclaimed. "Wouldn't that make him Captain America?"

"Pretty much." Qin Feng nodded. "The second optimization focuses on the brain. Memory, learning ability, and information processing ability will see an exponential increase. Do you know why I can handle so many complex tasks now? This is one of the reasons."

Qin Yao pondered as she recalled her brother's astonishing decisions and plans.

"The third optimization," Qin Feng paused, "hasn't reached its limit yet. I've optimized it three times myself, and now ordinary firearms are ineffective against me—not that I can't hit them, but that even if I do, it's useless."

The living room was completely silent.

Qin Jianguo and his wife looked at each other in bewilderment. They had experienced a lot in their lives, but this was still beyond their comprehension.

Qin Yang suddenly thought of something, his expression turning strange: "Brother, what if I get appendicitis after I've finished optimizing it? Won't the scalpel become dull?"

The question caught her off guard, and Qin Yao burst out laughing.

Qin Feng smiled and waved to the medical staff next to him: "Come on, remove my brother's appendix first, without anesthesia."

"No, no, no!" Qin Yang waved his hands repeatedly, "I was just kidding!"

After the laughter and joking, the atmosphere relaxed a bit.

Qin Feng looked at his parents, his tone sincere: "Dad, Mom, I know this sounds unbelievable. But please believe me, this technology is safe. I've personally tested it and it has undergone long-term verification. After the optimization is complete, your bodies will become healthier, younger, and your lifespans will be significantly extended."

Qin Jianguo and his wife exchanged a glance. They saw the sincerity and confidence in their eldest son's eyes, and they also saw the professional demeanor of the medical staff.

"Xiaofeng, you're right, we believe you." Qin Jianguo finally nodded, "But... isn't this a bit too much? We're so old, what are we doing all this for?"

"Dad, it's precisely because you're getting older that you need this even more," Qin Feng said. "I want you to live a long and healthy life, to see the achievements I've made, to see Yao Yao get married and have children, and to see Qin Yang settle down and start a family. I want you to enjoy life, instead of being troubled by aging and illness."

These words struck a chord with Qin Jianguo. He looked at his wife, then at his three children, and finally made up his mind: "Okay, let's give it a try."

Qin Yao raised her hand: "Me too! I want to become more beautiful!"

Qin Yang, not to be outdone, declared, "I want to become stronger! No, I'm already very strong... I want to become smarter!"

Qin Feng smiled: "Everyone gets a share. But let me make this clear—the optimization process won't be easy. After the first injection, your body will undergo restructuring, which will cause intense pain for about three days. The second and third injections will be better, but still uncomfortable. You need to be mentally prepared."

"I'm not afraid of pain." Qin Jianguo straightened his chest. "When your mother gave birth to you, I heard her screaming outside the delivery room. That's real pain. This little bit of pain is nothing."

Qin's mother glared at her husband reproachfully, but her eyes were full of laughter.

Preparations began quickly.

The medical team converted the villa's basement into a temporary medical center.

It is equipped with advanced monitoring equipment, life support systems, and four independent optimization chambers—looking like hibernation pods from a science fiction movie.

"Everyone, put on your medical gowns and then enter the optimization chamber," directed Dr. Qin, the team leader and a medical bio-engineer. "The first optimization will take 72 hours. We will monitor the entire process to ensure safety."

Qin Jianguo and his wife were a little nervous, but seeing Qin Feng's encouraging look, they did as instructed.

Qin Yang, however, was eager to try: "Bro, after the optimization, will I be able to dismantle a tank with my bare hands?"

"Theoretically, it's possible," Qin Feng said seriously, "but I don't recommend you try it—tanks are quite expensive."

Qin Yao was the last to enter the optimization pod. Lying on the soft mattress, she watched the transparent canopy slowly close, and suddenly felt a little scared: "Brother, does it really hurt?"
