When I opened my eyes, the sight in front of me stunned me for a moment. It is no longer a familiar bedroom, but a strange courtyard, surrounded by an ancient and mysterious atmosphere. I rubbed my eyes, trying to confirm if I was still dreaming, but everything around me was so real.

I realized that I had traveled through time.

This is a world I never imagined - the world of ninjas. I was in a training ground, surrounded by all kinds of strange equipment and mysterious runes. I tried to stand up, but found that my body seemed much lighter, as if full of strength.

I understand that in this world, I need to practice as a ninja and become stronger. This is the only way to survive.

I started trying to do basic physical training based on the plots in some ninja movies and anime that I remembered. I jumped, rolled, climbed, and constantly challenged my limits. Although my movements were awkward and slow at first, over time I gradually mastered these basic techniques.

In the process, I met many like-minded fellow ninjas. Some of them come from different families, and some have unique blood inheritance limits, but we all have the same goal - to become stronger and protect the peace of this world.

We sweat profusely in the training ground together, competing and learning from each other. I gradually learned more ninjutsu and taijutsu, and made many trustworthy friends.

However, the world is not peaceful. Various monsters and evil forces often appear, threatening the peace of this world. As ninjas, it is our duty to eliminate these threats.

In battle after battle, I gradually showed my strength. I used my ninjutsu and taijutsu to defeat those monsters who tried to destroy world peace. Every victory makes me more convinced that I have the ability to protect this world.

But I also understand that there is still a long road ahead. I need to continue to practice and become stronger in order to deal with more powerful enemies.

So, I returned to the training ground again. Every jump and every roll seems to be a challenge to the unknown future. I know that only by constantly getting stronger can I survive in this ninja world full of dangers and opportunities.
