I Opened a Ninja School in Another World

The best way to write a ninja academy in another world is for the protagonist to have a certain level of strength from the start, and then open his own academy. He absolutely must start from scratch and grow stronger. A setting like an urban fantasy where a character awakens their profession would be better, not a Western fantasy. What's the point of writing this book like this?

It's too drawn out, too detailed, and doesn't get to the point. Many of the bloodstains are actually useless. Mastering the Bloodstain Network allows for the free combination of various bloodstains, and the system could directly provide beginner and intermediate immortal bodies. The later stages of the Bloodstain Network and the establishment of the main school are too slow; they could be faster.

I don't understand why so few people are watching?
