Willow Ye traveled to the world of Naruto, but got the worst start.
He was riddled with bone diseases, had low fever and coughed up blood all year round, and his meridians were so fragile that he could hardly bear chakra.
But precisely because of this broken body, he had mastered chakra control to a level that was beyond the reach of ordinary people.
In order to survive, he could only study his disease while embarking on the path of medical ninja.
From the ninja school to the battlefield, from self-rescue to saving others, from the era of Shisui and Itachi to the new era of the ninja world.
This is the story of a sickly boy who struggles to survive and grow step by step in the world of Naruto, and eventually becomes a lifeline for others.
