Since Ao Kun hired those professional mercenaries as personal guards, Kun Sha transferred these original guards here to guard their secret passage.

It's heavily guarded, and no unrelated personnel are allowed to approach it. In the eyes of outsiders, this is a warehouse for storing valuable materials, and it is natural to send troops to guard it, and this is indeed an important warehouse for storing drug raw materials. Therefore, outsiders do not know that there is a secret passage that leads directly to the outside of the valley.

Seeing that all the guards were at their posts, Kun Sha whispered behind him, "Follow me to the exit and have a look" and walked inside. A guard behind him took two steps to get in front of Kunsha, and pressed on the edge of a row of shelves at the end of the warehouse, and the shelves slid silently to both sides, and a dark hole more than one person high was immediately revealed, and a cool breeze blew out of the hole.

The guard reached out and touched the cave wall again, and a string of dim lights immediately lit up in the dark cave, he turned around and shouted: "Flashlight", the guard in the house immediately took a few strong flashlights and ran over, and handed one to each of Kun Sha and several people, which was for fear of emergency use after the power was cut off in an emergency, and it was night, and it may also be used when walking out of the tunnel.

Ao Kun's manor is located in the middle of the hillside, about 2,000 meters away from the cliff behind, when Ao Kun built this manor, he considered the defense of the cliff, in case the enemy captured the cliff behind, and attacked the manor directly from the cliff, this distance has been out of the range of most rifles.

After the manor was built, they found that the manor was quite far from the cave that led directly to the mountain, and Kunsha wanted to strengthen the guard between the manor and the cave. But Ao Kun Yaoyao insisted on digging such a hole in the manor that led directly to the cave.

At that time, when this tunnel was built, they used their own troops, and did not use a single outsider, to ensure the secrecy of this secret passage. Facts have proved that Ao Kun's decision at that time was correct, after they entered here, they were repeatedly attacked by government troops and other drug lords into the canyon, and several times they used this secret passage to escape from death.

Several people raised their feet and walked to the cave, this distance is the tunnel they dug artificially on the hillside, the ground in the cave is paved with stone slabs, and the surrounding and top of the cave wall are like the tunnel of a coal mine, with logs secretly supporting the cave to prevent the cave from collapsing. The cave was filled with the smell of earth, and the air seemed a little damp.

One of the guards walked in the front, raised the AK47 assault rifle in his hand and pushed the bullet with a "bang", and drilled into the depths of the cave, Kun Sha followed closely behind him, and the other guard followed up in the cave and turned around and pressed a button, and the shelves outside the cave quietly closed again, covering the cave tightly.

Several people passed through this artificial tunnel, the ground in front of them suddenly became undulating, the strange rocks on the cave wall were craggy, and the caves of different widths and narrows extended ruggedly into the distance, and the air in the cave suddenly became dry, without the strong smell of earth in the artificial tunnel. Kunsha looked up and knew that he had entered the cave under the cliff at this time.

The cave is uneven, as the mountain extends left and right, the cave is sometimes spacious, sometimes narrow, a huge stone stretches out from the cave wall from time to time to block the way, the narrowest place needs people to squat to pass, the guards carefully lead the way in front, and turn around from time to time to remind Kun Sha to pay attention to the stones above his head and the rocks that suddenly appear under his feet.

Fortunately, a series of lighting lamps were installed in the cave, and the lights flickered on and off, obviously because the power output of the diesel generator was unstable, but it could also basically illuminate the terrain in the cave.

On the wall of the cave, every 1 or 20 meters, a pine branch torch is inserted between the stone crevices in case of power failure. In some spacious places in the cave, there are some chests marked with canned food and boxes of mineral water placed against the cave wall, and some shelves are fixed on the cave wall, on which are stacks of thick animal skins.

For this escape route, Ao Kun and several people can be described as painstaking. They not only considered the lighting in the cave, but also considered that once the canyon was occupied by the enemy, and there were enemies at the exit, they could ensure that they could survive in the cave for dozens of days in secrecy.

When Ao Kun and his gang planned to set up camp here, Ao Kun personally took several important backbones of the group and carefully surveyed in the canyon. The terrain of the canyon is steep, easy to defend and difficult to attack, and it is rich in natural resources, so it is indeed a good place to set up camp. At that time, their only concern was how to escape after being besieged here.

The terrain of the canyon is like a double-edged sword, although it is easy to defend and difficult to attack, it is also conducive to the opponent to surround from outside the valley. Although the canyon is rich in natural resources, there will be a large number of workers in the drug processing factory and soldiers guarding the canyon in the valley, with the scale of several thousand people, once besieged, no matter how rich the natural resources are, it will not be able to sustain the survival of thousands of people in the valley for a long time.

Therefore, in order to establish their base camp here, it is necessary to have a hidden retreat in case they are besieged for a long time, or to use the passage to escape in time after the opponent's heavy forces have attacked the canyon.

In order to find an escape route, Ao Kun ordered Kun Sha to lead people to explore hundreds of large and small caves on the long cliffs on both sides of the canyon. After nearly a month of exploration in Kunsha, he finally found this hidden cave on the cliff in the south that leads directly to the back mountain.

Ao Kun was overjoyed to hear the news and finally decided to establish his own base here. In the years that followed, they spent a lot of money to purchase advanced chemical equipment, built two large drug processing plants on the northern slope of the canyon, and built a large diesel generator set to provide electricity supply in the valley to ensure the lighting in the manor and the production of electricity for the drug processing plant on the opposite hillside.

With the expansion of their drug business, Ao Kun gradually expanded the scale of their manor, strengthened the connection between the manor and the cliff cave, and prepared an emergency power supply in the small courtyard outside the cave to ensure that the cave was lit in times of crisis.

Now, this canyon is like a small city, and Ao Kun and his gang have invested great manpower and material resources in it, and built quite complete infrastructure. This is the home of Ao Kun and his gang, and it is the treasure place where they gather their wealth. As a last resort, Ao Kun will never give up here lightly.

For decades, Ao Kun has continued to grow his power and expand his territory in the years of struggle with the government army and the surrounding drug lords. But he deeply knows that his rapid rise in the drug world will definitely arouse the strong envy of all forces, and they will definitely use all kinds of forces in every possible way to get rid of themselves and rob them of their territory and wealth.

He must be prepared for danger in times of peace and take precautions!
