On January 5, ai era 745, sunlight streamed through the windows of Bulma's house, illuminating the spacious living room. A figure sat cross-legged on the floor, eyes closed, his breathing steady and deep. This was Zhou Zilong, who had transmigrated and been living in this world for a year.

However, today's training made him feel an unprecedented bottleneck. He clearly felt that his strength had reached a critical point, and no matter how hard he tried, his strength could not advance further.

"Phew~! It's really not easy. It's been a year since I came to this world. My combat power has broken through from the original 10 to 200, but it seems I've encountered a bottleneck. My training seems unable to improve recently," Zhou Zilong opened his eyes, sighed softly, and a hint of confusion appeared in his gaze.

Just then, Xiao Ling's voice sounded in his mind: "Zilong, you can go and apprentice yourself to Master Roshi to push the plot forward a bit, learn some of Master Roshi's martial arts realm experience, and by the way, figure out your own martial arts. For the past year, you've still been in the stage of blindly groping around, so it's quite good that you've managed to raise your combat power to 200."

Zhou Zilong was startled, then nodded. He understood that Xiao Ling's suggestion was reasonable. Since transmigrating to this world, he had always relied on his own efforts and memories of the original work to cultivate. Although his progress was rapid, he ultimately lacked systematic guidance.

"You're right, Xiao Ling. I should seek higher-level guidance," Zhou Zilong made up his mind and turned to walk towards the bathroom to prepare for a bath. However, just as he was about to step into the bathroom, Xiao Ling's voice sounded again: "Zilong, I have some very bad news for you. After my observations during this period, I've detected that you're not the only one who has transmigrated to this world."

Zhou Zilong's footsteps paused, and a hint of surprise flashed in his eyes. He hadn't expected there to be other transmigrators in this world. "Xiao Ling, are you saying...?"

"Yes, this transmigrator also came with a system, just like you, but their system is bound to a villain. So, you might encounter many different situations in the Dragon Ball World in the future," Xiao Ling's voice carried a hint of worry.

Zhou Zilong's heart tightened. He understood what this meant. A transmigrator with a villain system would likely cause a much larger butterfly effect in this world, and he had to be prepared to face this unknown challenge.

"But I also have some good news for you," Xiao Ling's tone shifted. "This transmigrator is also very weak at the moment, and they are not on Earth, but on another planet. Furthermore, their system has not yet awakened. However, to deal with their system, I need to go into a dormant update. I hope that when Xiao Ling wakes up next time, Zilong's strength will have improved a lot."

Upon hearing this, Zhou Zilong breathed a sigh of relief. Although a potential threat existed, at least for now, he didn't need to worry too much. Moreover, he understood that Xiao Ling's dormant update was to better cope with future challenges.

"Okay, Xiao Ling, you go ahead. I will continue to work hard to improve my strength," Zhou Zilong said with a smile.

At this moment, in Bulma's laboratory, the lights were bright, and various instruments shimmered with the glow of technology. Zhou Zilong, having showered, stood by the window, gazing at the starry sky, his heart filled with determination. He turned around and said to Bulma, who was busy working: "Bulma, I might have to leave for a while."

Bulma stopped her work and looked up at Zhou Zilong. Her eyes, usually full of curiosity and vitality, were now filled with confusion and reluctance. She walked to Zhou Zilong's side and asked softly, "Huh? Zilong, where are you going?"

Over the past year, Zhou Zilong and Bulma's relationship had grown closer. The two not only supported each other in scientific research but also cared for each other in daily life. Their relationship had surpassed that of ordinary friends, and an indescribable affection was quietly growing between them.

Moreover, Bulma's father, Dr. Brief, greatly admired Zhou Zilong, who was skilled in both academics and martial arts. He not only gave Zhou Zilong 5% of Capsule Corporation's shares but also appointed him as a technical consultant for Capsule Corporation. If Bulma hadn't been underage, Dr. Brief might have even urged the two to start dating quickly.

Zhou Zilong took a deep breath and half-lied to Bulma.

"I need to go find a master to apprentice myself to and begin new martial arts training. Yesterday, I dreamed that Earth was invaded by an evil force, and I wanted to stop it but couldn't do anything. That feeling of powerlessness frustrated me. I hope to be able to protect you better in the future, as well as some other people I want to protect."

His words were full of steadfastness and determination.

Upon hearing this, Bulma's eyes flashed with surprise, but it was quickly replaced by understanding and support.

"Zilong, I believe you can do it," she said, her voice full of trust and encouragement.

Over the next few days, Zhou Zilong and Bulma prepared the items needed for the journey. Bulma used her intelligence to create some practical tools for Zhou Zilong, such as an energy detector and a portable communicator. Zhou Zilong, in turn, used his technological knowledge to create 30 robot bodyguards with a combat power of 1000 for Bulma and Dr. Brief, to cope with potential dangers.

On January 10, ai era 745, sunlight streamed through the clouds onto the land of West City, casting a golden glow over the bustling metropolis. Zhou Zilong stood at the entrance of Capsule Corporation, taking a deep breath of the fresh air, his heart filled with anticipation for the future. He was about to leave this familiar city and travel to a distant island to find the legendary martial arts master—Master Roshi, hoping to apprentice himself to him and further improve his strength.

After leaving Capsule Corporation, Zhou Zilong was not in a hurry to go to Kame House. He knew that to get Master Roshi to accept him as a disciple, mere enthusiasm was far from enough. So, he decided to prepare some gifts first to increase his chances of successful apprenticeship.

Zhou Zilong came to a bookstore and carefully selected several books suitable for Master Roshi to read. He knew that although Master Roshi was old, his desire for knowledge had never diminished. These books would not only enrich Master Roshi's spiritual world but also allow him to feel Zhou Zilong's sincerity and respect.

In addition to books, Zhou Zilong also purchased some practical items, such as tea sets, tea leaves, and some pre-made delicacies.

After preparing the gifts, Zhou Zilong went to a relatively secluded place. He took out a capsule, pressed it lightly, and a modified jet plane instantly appeared on the ground. This plane was modified by Zhou Zilong using capsule technology combined with his knowledge of mechanical design. It had a longer cruising range, enough to support him on his journey to Kame House on the island.

Zhou Zilong piloted the jet plane, soaring over the sea. The sea breeze brushed against his cheeks, bringing a hint of coolness. He admired the beautiful seascape while thinking about how to express his sincerity to Master Roshi.

Ten hours passed, and Zhou Zilong still hadn't found any trace of Kame House. He began to feel a little anxious, worried that he had missed his direction.

"It's been a long time since I've seen a plane fly by. It wouldn't be looking for me, would it?" At this moment, an old man on the sea, riding a Sea Turtle, wearing sunglasses and an orange casual shirt, holding a cloud-shaped staff, and carrying a large turtle shell on his back, muttered to himself after seeing Zhou Zilong's plane fly past.
