Wan Lin's mouth muttered: "The elevation of the South Mountain in front of the house is 390 meters, the elevation of the North Mountain behind the house is 400 meters, the slope of the east slope is 45 degrees, the cliff is 550 meters above sea level, the cliff is 85 degrees, the cliff is almost vertical, and the southwest is five kilometers away, and there is a primeval forest with an area of dozens of square kilometers," he said, and he quickly drew the mountains and forests on the paper with the above numbers

In the blink of an eye, he drew the terrain around his house, marked the detailed terrain number on it, and then handed the map to Li Dongsheng

Li Dongsheng took the drawing, glanced around, looked around the terrain, asked for a pencil from Wan Lin's hand, and marked the hidden positions of several team members on the map

He carefully studied the map for a while, frowned, and asked: "The terrain is good, easy to defend and difficult to attack, this location should be your ancestors considered the defense of the cold weapon generation at that time, but now the generation is different, once the enemy brigade occupies a commanding height around, it is possible to destroy your courtyard, our troops are too small, it is impossible to guard all directions, then where is our retreat?"

Prepare for a rainy day, and at this time, a good commander must have the elements and the issues that can be considered on the battlefield at any time

Wan Lin smiled and said, "Hehehe, don't worry, our ancestors have long considered the worst-case scenario in this place"

He stretched out his finger and pointed to the hillside behind the house, and continued: "There has always been a secret road in my house that leads directly to the back of the mountain behind the small courtyard, in case of emergency use in that era of war and chaos, and later my ancestors took their families to expand this secret road, and dug a tunnel connecting the secret road in all directions of the east, west, north and south, and the stone behind Mr. Yu is the entrance to the secret road on this hillside."

Li Dongsheng looked at the place not far behind him, Yu Jing was lying on his stomach and exclaimed: "Your ancestors are really thoughtful, once they are surrounded by the enemy, they can withdraw from this area at any time."

Wan Lin replied: "The vigilance of people who practice martial arts is very high, according to my grandfather, the ancestors chose this place to settle because they took a fancy to the terrain here that is easy to defend and difficult to attack, and later there was an incident of warlords and soldiers hunting beasts with guns, and after the ancestors realized the power of guns, they repaired the secret passage again, and dug emergency tunnels in all directions around it, which was also the best way to protect themselves at that time."

Li Dongsheng said with a smile on his face: "Okay, since there are such favorable terrain conditions, then we will use this as a battlefield for the total annihilation of the little devils, if they dare to come, let them stay here forever, you go and inform the surrounding team members, let them know the terrain and landform of this area, know the location of the entrance to each secret tunnel, and facilitate maneuvering in battle."

Wan Lin agreed, looked up at the sky, and said into the microphone: "Be careful, it may rain for a while," he said, quickly ran around the surrounding terrain, took the drawings and introduced the detailed terrain and the location of the entrance to the secret passage to each team member, and then ran back to Li Dongsheng

The team members who got Wan Lin's notice were all smiling happily, everyone really didn't expect that Wan Lin's hometown still had such a mystery

Wan Lin ran back to Li Dongsheng's side, nodded at him and said, "I have informed each member of the team about how to open the secret passage," he said, looking up at the sky again, and shouted into the microphone loudly: "All avoid the top of the mountain, pay attention to the thunder and lightning."

Hearing Wan Lin's reminder, Cheng Ru, who was lying on the top of the surrounding mountain on guard, quickly held a telescope to observe the movements around him, and then all retreated to the top of the mountain, found boulders, tree pits and other locations on the hillside, and took out raincoats from their equipment bags and put them beside them

Everyone was just about to stop, when the originally scattered black clouds in the air suddenly rolled up, like a black pillar of smoke, moving rapidly, quickly merging in the air, instantly covering the entire sky, and the mountains that had just been bright suddenly became dark like a dark night

"Huh" a lightning bolt across the mountain, "Kara" a loud sound, followed by lightning slashed to the hundred-year-old tree in the distance, the two hugged each other, and the big tree that could only surround was split in half from the top of the tree, a big partner, with countless sparks rising on the top of the mountain

Before the flames on the big tree were completely ignited, the soybean-sized raindrops "crackled" and smashed down from the air, instantly extinguishing the freshly lit flames

The deafening thunder sounded like it exploded in the ears of Xiaoya and Yu Jing, which made their eardrums "buzz", and several people hurriedly pulled the raincoat next to them and put it on their bodies

Xiaohua and Xiaobai saw that the commandos had all withdrawn from the top of the mountain in order to avoid the thunder and lightning, and ran to the two peaks in front of the house and behind the house respectively, standing on the two big rocks on the top of the mountain, facing the pouring rain, their eyes blazing around, not afraid of the thunder and lightning flashing in the air

Perhaps two little leopards are pondering: when the sky falls, there is a tall leopard family that can't be split by thunder

The torrential rain in the mountains came and went quickly, and in less than an hour, the dark clouds in the sky were blown by a sudden gust of wind and flew to the northwest, and a blue sky was revealed above everyone's heads

A sudden pouring rain washed away the dirty blood stains left by the little devils in the mountains, and also washed away the dust on the hillsides and trees, and the fresh air filled the mountains again, as if yesterday's vigorous incident had not happened at all

Li Dongsheng stretched out his hand to wipe the rain off his face, lifted the raincoat and hat on his head behind his head, and shook the water droplets on his face vigorously: "Report to Vice Minister Li, I am the pilot of the transport plane of the military region, we are twenty kilometers away from you, and now we are flying in the stratosphere at 6,000 meters, please tell me about the cloud situation above you," a clear voice suddenly came from his earphones

Li Dongsheng was overjoyed when he heard that the military region's transport plane had arrived, he looked up at the sky and replied quickly: "The ** layer above us has drifted away, and now there is a blue sky, which can reduce the altitude."

Li Dongsheng knows that the plane usually flies to the stratosphere above 5,000 meters during flight, avoiding the clouds below that may cause lightning, so as to ensure flight safety

"Roger," the pilot replied, and after a while, a small transport plane swooped down from a high altitude in the distance, reaching them, and spun over them, and then a string of black shadows floated out of the fuselage, and after a while, several mushroom-like umbrella flowers bloomed over the black hawk, and quickly floated towards the ground

When they arrived in Wanlin, several people were overjoyed, but no one expected these comrades-in-arms to arrive so quickly
