Long Life? I Backhandedly Contracted the Ultimate Imperial Weapon!

Su Qingxue, the reincarnation of the empress, was a little crooked. She was reincarnated as a war spirit with a magical weapon. She was arrogant and did not want to sign a contract and become someone else's possession, so she disguised herself as a disabled spiritual soldier and practiced alone. But she didn't expect that times have changed, and now all war spirits must have a contractor, otherwise their intelligence will be shattered and recast. "Does it mean that this emperor will die in such a painful way in this life?" Just when Su Qingxue was desperate, her neighbor Lin Yuan stood up and was willing to sign a contract with her, a "waste war spirit". Lin Yuan looks young, but in fact he has only a short lifespan. The war spirit that spent his whole life strengthening recently betrayed him. Perhaps he wanted to help her before he died, so he stepped forward to sign the contract. Su Qingxue felt grateful, thinking that Lin Yuan's life span was short, and the contract would be automatically terminated when his life span was exhausted, so he signed a contract with Lin Yuan. "Lin Yuan, I promise you that when I recover, I will make the war spirit who betrayed you kneel in front of your grave to admit his mistake." "Wait... What's going on with your life-span fire? The promised lifespan is running out?" "I also want to ask you this, where is the scrap battle spirit that we promised? How did it become the ultimate emperor's weapon? How do I develop it!?"
