Kenji was a determined teenager with a dream. He wanted to be the strongest man alive. Soon, he would start university, and he believed that strength would help him make new friends and stand out. Every day, he went to the gym, lifting weights and working hard. But no matter how hard he tried, his physique was not large. He felt small compared to the other gym-goers, and this made him sad. 

One day, after another exhausting workout, Kenji returned home and collapsed on his bed. He stared at the ceiling, thinking about what he could do to achieve his goal. It seemed like no matter how many hours he spent trying to build his muscles, he just wasn't getting anywhere. While he lay there, lost in thought, something unusual happened. A strange glowing light appeared in his room, and suddenly, a voice echoed around him. 

"Do you want to activate the System Strongest Man?" the voice asked. 

Kenji sat up in surprise. "What is that?" he wondered. But deep down, he knew he wanted to become stronger. "Yes!" he shouted, "I want to activate it!" 

"Your first task is simple," the voice continued. "Do 100 push-ups." 

Kenji jumped out of bed, eager to prove himself. He dropped to the floor and began counting. One, two, three... His muscles burned, but he pushed through the pain. When he finally reached 100, he fell to the floor, panting. 

"Task complete," the voice announced. "Now, you will receive more tasks to gain strength." 

The next day, Kenji asked for his following challenge. "What do I have to do now?" he asked excitedly. 

The voice replied, "You can choose between super speed or strength. Choose wisely." 

Kenji thought long and hard. He wanted to be the strongest. "I choose strength," he declared. 

"Your task is now to do 1,000 push-ups and also work on bicep curling," the voice instructed. 

"1,000 push-ups?" Kenji gasped, but he didn't back down. Determination filled him. He set his mind to it and spent the entire week completing the tasks. Each day was harder than the last, but he felt stronger. By the end of the week, he felt different. 

"Task complete," the voice echoed again. "You are now super strong." 

Kenji could hardly believe it. He flexed his arms and looked at his reflection in the mirror. His muscles had grown, and he felt incredible. With newfound strength, he rushed outside, excited to test his abilities. 

When he reached the city, he found a tall skyscraper. With a deep breath, he bent down and lifted it with both hands. The building felt surprisingly light, as if it was made of paper. Kenji stood there, holding the entire skyscraper over his head and smiling widely. He gently set it back down, careful not to damage anything, feeling like a superhero. 

But the voice returned. "Now, you may choose your next ability: super speed." 

Kenji thought about it and grinned. "Let's do it." 

"Your tasks are to do 1,000 squats and some jumping exercises," the voice instructed. 

Kenji felt a rush of excitement again. He moved to a large open space at the park, eager to start his exercises. He counted his squats, feeling his legs burn, but he didn't stop. Every squat brought him closer to his goal. After completing the squats, he moved on to jumping exercises—jumping high into the air and landing smoothly. 

Finally, exhaustion hit. Kenji felt his limbs become heavy, and before he knew it, he lay on the soft grass, fast asleep. 

In his dreams, Kenji found himself in a mysterious world filled with vibrant colors and strange creatures. He met a wise old man with a long beard who told him that true strength came not only from power and muscles but also from courage and determination. The old man encouraged Kenji to never give up, no matter the challenges he faced. 

When Kenji woke up, the sun was shining brightly in the sky. He felt refreshed and eager to continue his journey. "I have to complete my tasks," he reminded himself. 

With renewed energy, Kenji quickly got back up and prepared to activate the super speed tasks. He focused on breaking his limits and aimed to become not just strong but fast too. 

As Kenji trained, he felt something change within him. The warmth of determination surged through his veins. He was excited about the adventures waiting for him ahead. Each task he completed brought him closer to being the strongest, and he knew he could take on any challenges that life threw at him.
