At night.

Tang Zheng lay on the bed unable to fall asleep.

Outside, Luo Fei rested for four hours while Tang Zheng was awake.

He told Tang Zheng that they had more energy than ordinary people and could guarantee basic sleep by sleeping for four hours.

After Luo Fei woke up, he stood in front of Tang Zheng's bedroom door with a gun like a sentry, standing guard for Tang Zheng.

Tang Zheng refused to rest even after persuading him, and Tang Zheng stopped persuading him.

Lying on the bed, listening to the occasional howling of zombies coming from outside the window.

From time to time, there were screams from people, and someone was killed again.

The bright neon lights of the past no longer light up.

There are only a few lights in the city, flickering like will-o'-the-wisps.

The network is still working, but there are obviously fewer messages asking for help.

The empire did not officially send any news of rescue. There was originally an imperial duke in charge of governing Sanjiang City, but as of noon today, the duke also died.

What should he do?
