The sky.
The air force squad from the Han Zhong Military District piloted their fighter jets, whistling as they circled around.
Missiles exploded around the ship on the river's surface.
Water surged skyward, the valley shook, and rocks tumbled down.
After repeating the sweep several times, the squad leader signaled the other planes to cease fire.
He connected to the ship's broadcast and said:
"Yangtze River No. 7, proceed forward, the military grandmaster will conduct a comprehensive inspection of the ship."
The demons are very cunning, many are adept at invisibility and transformation techniques.
Therefore, any ship and personnel attacked by demons need to undergo the first security check.
Then, upon entering the military-controlled area near the base city, they undergo a second security check.
Finally, when goods and personnel enter the city, they undergo a third security check.
Even with this, it cannot completely prevent demon ghosts from infiltrating the base city.
