After about half an hour, the enemy camp gradually quieted down. It is estimated that no trace of the enemy was found, and it is believed that it was caused by a false alarm by the alarm system. All the enemies returned to their tents to continue their rest, and only a few sentries remained, continuing to stand guard.

The members of the squad touched the vicinity of the enemy camp again, this time they didn't dare to get too close, the mirage walked in front, about five hundred steps away from the enemy camp, and suddenly stopped, and now they didn't use the hidden butterfly on their bodies, because once they used it, they couldn't see each other anymore.

Everyone saw the mirage stop, and hurriedly followed suit, looking for a hidden place.

The Four Elders used the Hidden Butterfly on the mirage, and his form disappeared from everyone's sight.

The rest of the people could only wait patiently, and when there were about two teas, everyone felt that life was as uncomfortable as a year. Finally, Du Wu's heart moved, as if he felt something, a figure in front of him slowly appeared, it turned out that the mirage demon took off the hidden butterfly on his body, and he returned to everyone.

When Du Wu saw that the mirage had a very big mouth and a happy face, he knew that it was most likely a success. But I still couldn't help asking: "Xiaobei Xiaobei, how is it, have you found it?"

The mirage demon hurriedly took out a jade bottle from his arms, handed it to the four elders, and said to everyone: "Master, elders, Xiao Bei is fortunate not to be dishonored, the thing here should be the spirit Gu." ”

The four elders took the jade bottle. She didn't open it, she said to Du Wu: "Princess, everyone, if it is about to dawn today, we can't continue to act tonight, why don't we leave for a while and go to a secluded place, wait for me to study it, how to deal with this spirit Gu, and tomorrow night, we will come to burn food again." ”

As soon as everyone heard the reason, they all nodded in agreement.

The group quietly left the enemy camp and found a valley about twenty miles away from the enemy camp, which was extremely secretive, and everyone stopped here.

Elder Shaohan looked for a flat boulder, took out the jade bottle, spread a clean handkerchief on the boulder, opened the lid of the jade bottle, and poured out the contents inside.

Everyone gathered around, only to see that they were a few small insects, and the insects looked very strange, without feet and wings, and looked like a meat egg. The strangest thing is that he doesn't even have eyes, but he has a protrusion that resembles a tentacle in the front of his body. The protrusion kept turning direction, and when it turned to the direction of a person, it suddenly seemed to feel something, and the body of the insect vibrated violently, as if it was extremely frightened.

The fourth elder asked the mirage, "Xiaobei, how did you catch them, and where did the enemy hide them?"

The mirage replied: "Elder Grandma, Xiao Bei has a very strong perception of this kind of Gu, and just now I searched with my heart and found that these little things were actually buried in some metal balls in the ground, and the metal balls were connected together through some metal filaments, which should go straight to the inside of the camp. ”

Elder Shaohan nodded and said, "Xiaobei, you have made a great contribution this time, and I will ask the princess to reward you well." ”

The mirage hurriedly replied: "Grandma's words are serious, this is a matter within Xiaobei's share, and she can share her worries for her master, fortunately!"

When everyone heard him actually pull up the text, they couldn't help but be amused.

The fourth elder said: " Princess, seniors, Shao Han now basically understands how the enemy's alarm system works, the enemy buries these spirit Gu underground, around the barracks, no one can find it, but the spirit Gu can feel the breath of human beings, once someone approaches the defense circle formed by the spirit Gu, the spirit Gu vibrates violently because of fear, this vibration will be transmitted to the enemy's camp tent through metal balls and metal filaments, and the camp must be connected with extremely sensitive bells and other things, once the vibration occurs, it will send out a sound warning, and the enemy will find that someone has invaded。 ”
