Wind Knife carefully observed the terrain of the mountainside, and suddenly felt nervous in his heart: now, if the leopard head wants to sneak into the canyon secretly, he can only go through the enemy checkpoint where the guò groove is located.

However, in such terrain conditions, it is almost impossible not to alert the enemy in the checkpoint to sneak in. The only way for the leopard head to do so now is to quietly take out a few enemies in the outpost and then secretly enter the enemy's base along the hillside below the ladder.

Just when the heart of the wind knife was beating wildly in tension, a low voice suddenly came from the base, and then I saw that on the dim hillside on both sides of the valley mouth, four shadowy figures appeared, and they were walking unhurriedly on the hillside towards the soft ladder hanging in the air and hanging halfway up the mountainside.

The enemy has changed the guard! The wind knife reacted immediately, and a cold sweat immediately broke out on his body, lest the leopard head and Xiaohua attack at this time, he quickly tapped the microphone lightly, reminded the leopard head to pay attention, and then raised his hand to put a grenade next to him, and then gently pulled the bolt, moving the muzzle of the gun to aim at several black shadows on the mountainside on the left, ready to provide support for the leopard head at any time.

At this time, Wan Lin, who was hidden next to a rock on the side of the groove, also suddenly found two teams of people and horses suddenly drilled out of the foot of the mountain on both sides of the canyon, and he was shocked into a cold sweat.

Just now, he and Xiaohua approached the side of the enemy's mountainside outpost in concealment, and he found that there was a rock in front of him that was less than half a meter protruding, just enough to hide his and Xiaohua's figures, and he could probe to observe the enemy outpost in the groove.

But at this moment, the mountain hound suddenly barked wildly, and he immediately realized that he had been discovered by a fierce dog with a keen sense of smell and hearing. He hurriedly pointed to Xiaohua behind the mountain, and then made a few gestures.

Xiaohua immediately rushed along the cliff to the back of the mountain, and then let out a roar and blue light, and at once suppressed the barking fierce dogs in the valley.

Wan Lin hid on the steep rock wall, his two toes on a slightly protruding rock, one hand tightly clutched a narrow stone crack above his head, supporting his full body weight.

After quiet in the valley, he poked his head out of the hidden stone wall and glanced at the valley, and saw that the groups of terrorists who had just poured out had returned to their dormitories, and there was no longer a single figure in the canyon.

He let out a sigh of relief, kicked the stone wall under his feet, and threw himself into the air, hooking the edge of a raised rock on the edge of the groove with a steel hook in both hands, and then his body immediately clung to the steep rock, and then found a slightly raised rock under his feet and stepped on it.

He moved with great dexterity, quickly fixed his body on the rock wall, and then slowly poked his head out to the side.

The barrel of a heavy machine gun in the groove protruded diagonally from the side of the rock, and he could reach the body of the black hole, and the distance between the two sides was already within reach.

Wan Lin immediately held his breath, turned his head to look in the direction behind the mountain, and saw that Xiaohua was quietly rushing towards him. He then slowly twisted his head again, observing the defenses of the enemy base.

At the foot of the hill on both sides of the gate of the valley, there is a semicircular fortification, on which several light and heavy machine guns are placed, but the fortifications are empty. He looked behind him in amazement, and saw that on the hillside behind the two fortifications, there was a low house, and a glimmer of fire was faintly revealing from the cracks in the wooden houses.

Wan Lin suddenly understood that in this cold temperature, these terrorists on guard at the valley mouth all retreated into the small cabin behind, and the guard outside the valley was monitored by the guard posts built on the mountainsides on both sides of the valley.

He then quietly poked his head out and looked into the depths of the valley, which was pitch black, several kilometers away, and a high mountain in the distance was hiding the mouth of the valley on the other side.

Obviously, this is a relatively enclosed canyon, with the valley facing north and south, and the steep mountains on both sides and behind it not only protect it from attackers, but also provide shelter from the cold northwest winds of winter. Judging from the mountain, the steep mountain located in the northernmost part of the canyon is very likely to have a hidden escape route.

Wan Lin's eyes quickly observed the general terrain in the valley, and secretly said in his heart: Looking at the topography here, it is indeed a good place to defend and retreat in a crisis. Since these terrorists have established a base here, it means that there must be people who understand military affairs in them.

His gaze then looked into the bleak valley. In the dimly lit canyon, rows of neat huts were built on the slopes on both sides, and some of the houses also showed a faint glow of fire. Obviously, this row of wooden houses is where the terrorists live, and it is estimated that there are four or five hundred terrorists gathered in the canyon here.

Wan Lin was shocked in his heart after reading it: "Good guy, the terrorists here are actually on such a large scale!" It is no wonder that they have established such good relations with the local armed forces of various factions in the local area. In a war-torn environment, this armed force is a force that must be fought over against any force."

He immediately estimated the number of houses on the hillsides on both sides of the valley, and said secretly in his heart: "Good guy, there are at least more than 200 row houses densely packed on both sides of this hillside, and counting the two or three hundred armed men who went out to reinforce just now, there are at least more than 100 terrorists here. The guards here must not be alerted now, otherwise it will be difficult to find a target in the narrow canyon and carry out the killing."

He frowned and looked up in the direction of the mountaintop, looking for another way to avoid the secret infiltration of the outpost in front of him.

The sheer cliff wall stretched from top of his head to the top of the mountain, and once he climbed on the steep cliff face, he could not hide from the gaze of the sentinels on the opposite mountainside and the bottom of the valley.

He shook his head slightly, and immediately dismissed the plan. Now, except for passing by the enemy post in front of you, it is simply impossible to enter the canyon covertly without alerting the enemy.

His eyes were immediately locked on the outpost in front of him, and he knew that he now had no choice but to take out a few enemy sentries in the recess by surprise and sneak into the valley!

He then quietly took out a steel needle from his waist, lifted his true qi and focused on the groove in front of him. Gradually, from the breath of life coming out of the groove, he had already identified that there were four sentries in the outpost, two of them were on the edge of the groove on his side, probably the two who had smoked just now, and the other two seemed to be sitting not far behind them, and were now snoring softly.

Wan Lin judged the situation in the outpost, gritted the root of his teeth, looked up at the small flower that had been running, and suddenly raised his hand and waved it, just as his arm swung to the side of the rock, and was about to let go of the steel needle, the corner of his eye suddenly flashed in the groove on the opposite mountainside, and a figure bowed his head and lit a cigarette in the direction where he was.
