In interrogation room No. 76, Shen Muhan used his newly forged identity to let the traitor kill the military commander's backstabber. When he walked out of the door, the little girl selling cigarettes on the street looked at him suspiciously - the system had erased her father's existence three days ago, and now no one remembers that the man was a traffic officer of the underground party. He hid the gun and ran to the alley where they agreed to meet. The menorah is not there. Only the broken string kites were drawn in chalk on the walls - the death signal of a single severed string. Shen Muhan pressed his forehead, where Shadow Walker's burn marks began to appear. He must find the candlestick within 72 hours, otherwise he will be permanently lost. But Masao Sato from Special High School Class 76 stared at him, female military agent Mu Qiutang tested him, and a man claiming to be his brother Shen Muguo suddenly appeared - but Shen Muguo died three years ago. When he opened the fake identity system to query "Shen Muhan", there was only one line on the screen: This identity was generated by a forgotten civilian, and it would collapse retroactively.
