Spy War-Black Notarization

His gun went off! The head in the scope looks like a watermelon! He fell down, in front of his wife's grave! He is alive again, reborn in this war-torn era!

In this dark age, the law cannot judge you, the sinful traitors, so let me judge you instead of notarization! This novel and its characters are purely fictitious.
