I Have Been Using Inkstones for Thousands of Years, but You Are the One Who Will Come Later

In the battle of Yanmen Pass, Dingyuan General Lin Yan died on the battlefield. His only obsession before he died was not fulfilling his promise to marry her. When he opened his eyes again, he became the cold transfer student who was feared by everyone in Ningcheng No. 2 Middle School. Taciturn, distant, and with an aura that doesn't allow strangers to approach him, no one knows that this young body contains a soul that spans thousands of years. Everyone thought he was cold and unapproachable, only Shen Wan knew—— When she was being made things difficult for her, he stood in front of her calmly; When she fell into a coma due to fever, he stayed up all night making porridge and giving her medicine; He remembers her favorite food, her fear of the dark, and the little habits she keeps deep in her heart better than anyone else. Everyone asked why Lin Yan made an exception for her. Only Lin Yan himself knows this. He came here after thousands of years of travel and dust, just to make up for an engagement that was thousands of years late. The girl he failed to protect in his previous life, he will protect her in this life.
