God gave Chen Jin a heart that could not bear to see the suffering of the world, but it did not give him the ability to save anyone.
He is just a senior high school student in Wuling No. 3 Middle School with a neural adaptation rate of only 31. He attends classes during the day and works at the night flight maintenance station after school. He is used to lowering his head, being patient, and telling himself: Don't cause trouble.
Until that day, he came into contact with a red-labeled scrap armor that was judged to be "unconscious" in the scrap armor warehouse.
Everyone said it was dead.
Only Chen Jin heard the remnant sound.
"... Late..."
The legacy of the Dark Moon, the strange beasts of the mountains and seas, the ancient covenant, and the sleeping mechas are all buried under layers of neon and steel in the modern city.
And that useless armor named "Jianshan" has been waiting for him for a long time.
When the mountains and seas return, the world on which mankind relies for stability begins to crack.
Chen Jin finally understood that some things were not beyond saving.
It was everyone who sentenced it to death too early.
This is a story about young people, useless armor, mountains and seas, and forgetfulness.
It is also the first time for an ordinary person to decide:
I can't pretend not to see it.
