The Saint's Sword Spirit Ran Away from Home

Jiang Zhiyue was born into a new life, but as the spirit of a sword. With the System's help, she promptly escaped from the sword and ran away. Fu Jingqi never uses his spirit sword. Not because it's too powerful, but because it's a useless sword with a fancy appearance that can't be upgraded. But one day, Fu Jingqi discovers that his sword has gained a spirit. Then, one day, he discovers that his sword spirit has disappeared, and that his sword can now be upgraded. Theme: Unity and friendship!
