Liu Guohao and his two comrades ran up to the stairwell entrance and saw an American soldier who had been turned into a mass of mutilated flesh. His legs, smeared with visceral matter, were twisted irregularly, and they nearly vomited at the sight. These weren't zombies, but a living, breathing person, which made it even harder to accept.
Tang Zheng swung his left fist silently, gesturing for silence, and quickly peeked into the corridor. Across the stairwell, a soldier was firing, blocking the escape route of Dong Zixuan's group. It seemed there were also soldiers guarding the room across from Room 907, occasionally lobbing hand grenades and suppressing with a general-purpose machine gun, showing off formidable firepower.
The American soldiers were highly skilled. Ten seconds after Tang Zheng's group opened fire, inquiries came from the blood-stained walkie-talkie on the ground.
