The useless princess is causing trouble again

The Black Evil Army camp is backed by a bare mountain, and a barrier is set up in front of it, making it easy to defend but difficult to attack; four sentinels stand at the gate of the camp, they are tall and mighty, with serious faces, holding long spiked knives in their hands; the sound of synchronized footsteps can be heard all around the camp, and three patrol teams are patrolling around the camp without sleep.

The three large granaries are located at the foot of the mountain in the north. They are heavily guarded on all sides. Eighteen patrol guards patrol back and forth. They are very vigilant and will pay attention to any slight movement.

Shangguan Wei used the agency's navigation system to evade layers of strict surveillance and led Situ Chong to the foot of the mountain in the north. The two hid behind a large rock halfway up the mountain.

Half an incense stick of time passed, and the number of patrolmen near the granary increased. Shangguan Wei sighed, holding her chin with her right hand and thinking. After a moment of silence, her eyes suddenly lit up, and she took out a treasure from the space and immediately assembled it. Situ Chong squatted on the left side of Shangguan Wei, watching her tinkering with things carefully, and asked in a low voice, "Madam, what are you doing? Do you need your husband's help?"

Shangguan Wei shook her head and replied, "No need to help, just watch the situation from the side. Once I assemble this little thing, I can burn down several granaries without having to go down."

Hearing this, Situ Chong was very curious, "This little thing is so powerful, has Madam given it a name?"

Shangguan Wei smiled with her eyebrows curved, "Hehe! This is called a remote-controlled drone. According to the manual operation of the sensor, the drone can attack the granary silently, and then we can retreat safely."

"The drone comes and goes without a trace, and can paralyze the enemy very well. I am eager to witness its power."

Situ Chong looked at the little thing in Shangguan Wei's hand with deep anticipation in his eyes.

"Hehe! I've done it. Now I'm going to show you how powerful it is. Don't blink!"

Shangguan Wei assembled the remote-controlled drone and held it in front of Situ Chong to take credit. Her rosy cheeks looked very cute. Situ Chong smiled softly and said softly, "Okay, I will watch from the side. If you need help, just let me know."

"Well, Chong, take the drone in your hand. I need to put something in it."

Situ Chong picked up the drone and held it in front of his chest. Shangguan Wei put five smoke bombs into the fuselage and then pressed the start button on the operating template. The drone flapped its two wings and slowly flew into the air. Under the cover of night, it quickly flew over the granary. After locking onto three targets, it pressed the release button and the drone dropped smokeless bombs one by one.

Shangguan Wei raised her lips and smiled, "Hehe! Three minutes left, the show is about to begin. But the drone still has two smokeless bombs, which will be dropped on the main tent and the stable respectively, catching them off guard."

Situ Chong nodded in agreement, "Madam, your idea is very good. I fully agree with it. Let's retreat when they start to riot."

"Okay, when they start to fight the fire, we'll take advantage of the chaos and run."

Shangguan Wei pressed the joystick with her right hand to fix it in the positive direction. The drone flew quickly towards the stable, dropped the smokeless bomb and continued to fly forward. Finally, it hovered over the brightly lit main tent and dropped the smokeless bomb again. After doing everything, the drone returned along the same route.

Before a cup of tea was up, the drone returned to Situ Chong accurately. Situ Chong felt it was amazing, but he didn't have time to explore it further. Five locations below had caught fire. The smokeless bomb was powerful, and the fire spread quickly, instantly turning the granary and stable into a sea of ​​fire. There was a lot of noise around, and the camp was in chaos.

Seeing this, Situ Chong said, "Madam, let's retreat. If we are late, it will attract the attention of the King of Lingnan."

"Well, let's retreat!"

"Okay, I'll be able to go faster if I hold you."

"Wait a minute, let's go over there."

Shangguan Wei put the drone into her sleeve, stood up, and pointed her right index finger in the direction of retreat; Situ Chong picked up Shangguan Wei horizontally, used his lightness skills to leap up from the spot, and as light as a swallow, he quickly disappeared halfway up the mountain.

In the tent opposite the main camp, Lingnan King Cheng Yi had already fallen asleep. He was suddenly awakened by a cry for help outside. He opened his confused eyes and shouted unhappily, "Lieyi, what's going on? It's so noisy outside?" He sat up with a headache, holding his forehead with his right hand and looking towards the tent door.

But before Lie Yi could answer, a clear, pleasant and anxious voice sounded, "Father, something bad has happened. Our granary and stables have been burned, and even the main tent has not been spared."

Upon hearing the noise, Cheng Yi jumped out of bed and ran out of the tent door without caring about his image. He looked straight at the burning main tent opposite him, and raised his head to see the thick smoke rising from the north. His anger was rising, and he roared with foam at the mouth, "Who did this? Who did this? I will not let him off easily. I will tear him into pieces and send the Falcon team to search for him."

The girl in black stood aside, staring at the fire in front of her, and slowly said, "Father, don't be angry. This general has ordered the Falcon Commando to put out the fire and search for the suspects. As for who did it, it must be the Southern Frontier Army that set fire to the granary and stables, mainly to hinder the Black Evil Army's offensive."

Cheng Yi was silent for a moment, then took a deep breath, "Xin'er, you don't have to bother looking for him. He was able to evade the tight defense and easily enter the camp. This person must be an excellent martial artist and should have escaped long ago. You should accompany your father to the granary and stables to minimize the losses."

The black-clad girl cupped her hands and said, "As you command! It's dark and the road is slippery. The danger has not been eliminated. Father, please follow me."

Lie Yi, who was standing behind him, coughed lightly, "Your Majesty, let me help you tidy up your appearance."

Cheng Yi looked down and saw his bare feet. He frowned and said, "Go quickly and get me my coat and boots."

Lie Yi said "OK" and turned to walk into the tent.
