God Killer: Was He Sacrificed at the Beginning? Fortunately, I Kept It

[King of Start] + [Hot Blood] + [Decisive Killing] I, the first-generation hero, have been guarding the tomb for hundreds of years. As soon as I came out of the coffin, I was treated as a useless living corpse by the current empress! The next second, the [Hall of Valor System] was activated. I inherited the legacy of thousands of comrades in arms, lying in the coffin and blasting the evil god with one finger! "My life is not long, but whoever dares to touch my Daxia, God will kill you!" Killing a god with one sword and counting down her life for 72 hours. The empress was so frightened that she cried and begged me not to die! Ridiculous! The technological major general actually said that I was a disposable "biological switch"? You still want to use high-voltage electricity to "test" my withered corpse and pull out my oxygen tube? ! Unexpectedly, this is just the beginning. The real enemy is actually the "history tamperer" who attempts to completely obliterate all my heroic comrades from upstream in time!
