When everyone rushed to the outside of the cave, it was almost dusk, and the sunset was like fire, shining the heavens and the earth golden. Yu Jingying, www.biquge.info of the pen "Fun" Pavilion, looked at a black hole standing in front of her, and couldn't help but feel a little scared. She asked Sun Mudao, "There won't be tigers and snakes in this, right? Even if there are no tigers and snakes, rats and bats and the like are quite scary." Sun Mu didn't have time to answer, Xiang Wan began to ask again, "This place is indeed remote, but this cave entrance is extremely conspicuous, in case someone walks here and spreads the news, isn't it going to be caught in the urn?" Yu Dayou and Shangguan Hongyang also looked puzzled, and the two of them didn't understand why Sun Mu led everyone to this cave, everyone here has two hits, tigers and poisonous snakes don't have to be afraid, and rats and bats are just a joke, but if you really want to be targeted, surround the mouth of the cave, it is really difficult to fly.

Sun Mu saw everyone's doubts. He smiled and said, "Your suspicions are well founded. But that's only because you're far from knowing the secrets of this cave. Come with me. Sun Mu pushed forward the wooden fence at the entrance of the cave, took the lead into the cave, and lit the fire barrels inside in turn, which were full of flammable grease and the like. Sun Mu said with a smile, "There are a total of sixty-six fire barrels in it, and when lit, it can illuminate the cave as if it were daylight, which beast and poisonous snake dare to entrench here?" But now it's summer, it's already hot, let's light six fire barrels first, enough for lighting." As the flames grew louder and louder, everything inside the cave was clearly visible to everyone. Shangguan Hongyang roughly estimated with a pair of naked eyes, this cave is about two acres in size, about two zhang high, it looks very empty, and you can still hear the faint wind from time to time, obviously the ventilation conditions are good. Sun Mu introduced to everyone one by one, "Look, there is a small pond in the low-lying area to the east, which is connected to the underground spring, and the sixty fire buckets are placed next to the pool. It can be used not only for lighting, but also for defense. The sixty fire barrels were neatly placed behind the wooden fence at the entrance of the cave, and all of them were tied with iron wires, and once they were all burned, the huge fire formed could burn for four whole hours, and no one could be approached within a kilometer, and not even a single mosquito could fly in. What are we still worried about the encirclement of the enemy?"

Yu Dayou said, "This defense is indeed innovative, and it sounds flawless." But the question is, aren't we trapped in it ourselves? Even if we don't suffocate, this fire will eventually be extinguished. When the time comes, what will the enemy do?"

Sun Mu smiled, "It's okay. Let's take a look at the stone gate on the west side. Behind the stone gate is a tunnel that leads to the back of the mountain. By the time the flames were extinguished and the enemy had attacked, we had been able to escape from the back of the mountain for at least four hours. Hahahaha. Yu Dayou also smiled, "Haha, I understand, it's a good trick for the golden cicada to get out of its shell." ”

Yu Jingying still didn't quite understand, and said, "What if the people of the Sea Gang can't search here? Isn't your careful arrangement in vain?" Sun Mu was almost speechless. Still replied to Xiang Wan, "That's not right. You see that on the wooden beam on the north side, there are bacon, sausages, and the like, and several jars of wine are piled up underneath. Everyone eats and drinks well every day, sings about wine, and recuperates from injuries while fleeing. It's like a camping in the wilderness. Isn't that interesting?"

Sun Mu laughed and said, "That's not all. As you can notice, there is also a small school martial arts field near the entrance of the cave to the south, with swords, clubs, and so on. Wouldn't we be able to pass some boring time if we talked to each other?"

Yu Dayou exclaimed, "Not bad, very good, you think very well, and all aspects have been considered." If you join the military, you must be a general. But we still can't be too careless, we have to do the preparation work in advance. Like this wooden fence, it had to be closed first, and the fire barrels had to be stacked at the mouth of the hole first, and first tightened with wire. Whoever wants to go out and take some breath can do so by climbing over the fence. In addition, outside the entrance of the cave, some people must also be arranged to guard it to prevent the people of the Sea Gang from sneaking up. We don't fight unprepared battles. ”

After Sun Mu heard Yu Dayou's appreciation, he was flattered, and quickly nodded yes, "Yes, yes, yes, okay, just do what you say, General Yu." ”
