(Dragon Ball fanfiction + transmigrated into Future Trunks + single heroine + Future Timeline)
This is West City, once a prosperous home, now nothing but a distant memory. The bustling commercial streets have become scorched earth, while the once lively high-rises are now reduced to crumbling ruins.
The warriors paid a terrible price. Their blood stained the earth as one heroic figure after another fell.
But they never gave up, because they knew that as long as there was even a glimmer of hope, they could never stop fighting.
Golden flames reignited in the desperate, rain-soaked night. They were the light of hope, a steadfast belief in the future.
(P.S. The story may visit other worlds later, but I haven't decided yet. Please share your suggestions! Many thanks!)
The subject matter is good, but it's too watery
To be honest, I feel that the role of the time traveler is not highlighted. You have not transformed after traveling for so long. Where is your foresight?
Time and space can be changed. For example, Zamasu destroyed a lot of time and space.
