บท 153: The Evil Spirit Insect

The government's underground city plan was grand. The underground complex took up a vast area and had all kinds of facilities.

To avoid being discovered by the evil spirits, and not knowing the specific situation of the evil spirit stronghold, Ning Shi did not dare to rashly investigate the buildings after losing the trail of the evil spirit assassin.

However, he was not in a hurry. Not only did he not stay in the underground city for long, but he also went back the same way he came. He stood guard near the crack in the rock wall where the evil spirit assassin had just entered.

Ning Shi believed that there would be more evil spirit assassins who would return.

He waited for more than six hours at the crack in the rock wall, until three o'clock in the morning. Just as Ning Shi was about to give up and go back to school to think about it, another evil spirit assassin turned into light smoke and appeared at the foot of Green Dragon Mountain.
