Get in the car and start and continue heading ahead. The terrain in the valley has begun to become rugged, and the horizontal drop from the ground has increased from about 15 meters to about 20 meters, and the range does not fluctuate much. The valley walls on both sides are steep, and after two kilometers of progress, there is still no passage for a medium-sized animal such as a wolf, let alone a wide road suitable for off-road vehicles.

Just as the two of them were about to give up after another three kilometers, a concave appeared 50 meters ahead, and the bottom of the concave was densely scattered with some paw prints similar to wolves or dogs. Xu Qiang and the others have seen dog paw prints, but there have been no dogs in this world, or dogs domesticated by humans have appeared. But in this barren land, uninhabited scorched earth, the likelihood of a dog that is highly dependent on humans is extremely low. So, to be precise, those paw prints should be wolf-like imprints.

The presence of these traces here can only indicate one thing, this is a passage to the ground above, at least a passage suitable for wolves.

Xu Qiang stepped on the accelerator lightly, and reached the concave surface in a few breaths, and an upward passage that was only more than two meters wide appeared in the sight of the two. Luo Fatzi, who was sitting in the co-pilot, gasped.

The road surface can no longer be described as rugged, the twists and turns are steep, and the maximum climb from the bottom up is similar to the place where you just came down, but the difficulty of rushing from the bottom up will be three to five times more difficult than the down, and the danger will increase tenfold. The drop is 20 meters, but the height of these 20 meters will be difficult.

Moreover, in the place where the slope is about to be reached, there is a stone protruding about 50 centimeters from the slope, which will become an obstacle for Xu Qiang and the two to reach the top of the slope. Of course, the two of them can stay away from this danger, and it will be much safer to choose to climb on foot. But their partner will be abandoned, which is not acceptable to the two of them at the moment, and when there is gas or a car to drive, it is a great help, and they have already considered it a real partner.

"Let's go, fatty, let's go up and have a look." Xu Qiang took out a long-handled shovel from the car, handed the fire axe to the fat man, and called him to go to the top of the slope to see if he could dig out the stone, or knock down the stone more than 20 centimeters, and behead the last roadblocker.

Bang bang

Walking in front of the stone, Luo Fatzi hit the stone twice in a row with the back of the elimination axe, and with three points of force, he dropped some broken stones, the size of quail eggs, not very hard. Xu Qiang, on the other hand, used a shovel to dig half a meter deep around the stone, but still couldn't see the root of the stone, and it seemed that it would not be a matter of time or a half to dig it out.

The sound of banging kept sounding, and after Xu Qiang and the two rotated twice, they finally knocked off the stone by about thirty centimeters to ensure that the vehicle could pass normally.

While Luo Fatzi was cleaning up other larger stones on the slope, Xu Qiang observed at the top of the slope for a while and found a relatively thick stump, the roots of which were deeply rooted in the soil. Xu Qiang roughly measured it with his own footsteps, about 28 meters from the bottom of the valley. He returned to the off-road vehicle and took out a nine-meter-long tow rope, connected the hooks at both ends with the tow hook on the winch at the front of the car, and the tow rope folded in half was close to 30 meters long with the 25-meter-long winch rope, and he was ready to tie the tow rope to the tree stump in the middle of the hill to increase the safety factor at the top of the slope, and Luo Fatzi was responsible for controlling the winch switch and cooperating with Xu Qiang to tighten the winch rope.

After observing the slope back and forth three times and repeatedly confirming the plan to reach the top, Xu Qiang started the car and began to challenge the slope that he had never dared to challenge in modern society. All the heavy objects on the car were placed in place, including the corpses of the three wolves, just to reduce the weight of the off-road vehicle and increase the success rate of the hill.

The engine roared, the pickup truck sprinted at a speed of sixty yards for a distance and then rushed up the slope, and after continuing to move forward for ten meters, Xu Qiang quickly switched to the first gear, increased the throttle output, and the strong power of the engine drove the vehicle to climb up at a constant speed. There is still room for power in the first half of the race, and after entering the second half, the speed of the car before the car is significantly reduced, but the forward momentum is still undiminished, and the engine speed has increased to 4,000 rpm. In four-wheel drive mode, the body twists back and forth, and the force generated by the friction between the wheels and the ground will bounce the body uncontrollably, and the dust raised behind the wheels is overwhelming, and the stones are flying, hitting the ground and popping.

After 5 meters, the sound of the engine has begun to roar, and the rev has increased to 6,000 rpm. In the loud roar, Xu Qiang's voice came out:

"Fatty, quick, leash!"

Luo Fatzi, who had already dragged the rope in front, had already come to the stump, quickly put the folded trailer rope on the stump, quickly turned around and rushed to the off-road vehicle that was still moving forward, took out the winch controller, started the switch, and the winch rope was quickly tightened.

With a crunch, the winch rope was pulled faster than the off-road vehicle was moving forward, the motor beeped overwhelmed, and the winch rope, which could withstand 12,500 pounds of tension, collapsed tightly and hummed. With the joint efforts of the two, the off-road vehicle still struggled forward, and the body kept swinging back and forth on the slope, like a fish tied to a fishing line, desperately struggling in the water, just to escape to the deep water and gain freedom. And now the body of the off-road vehicle swings, just to be able to add more forward momentum and be able to successfully reach the top.

The engine has begun to roar, the speed has reached the red alert area of 7,000 rpm, and the sound of the engine is like a thousand oxen galloping, like a hundred tigers roaring in the forest, and it wants to tear the sky; The exhaust pipe spews out a large amount of white exhaust gas, which merges with the ash of the rear wheel to form a majestic smoke and dust, like a dragon spitting fog, like a mirage spitting shadows, straight into the sky.

There are still five meters to go, and we are about to reach the big rock. Luo Fatzi, who controlled the winch motor, had sweaty palms in his hands, and his expression was nervous to the top, lest he control the motor too much force and cause the winch rope to break, causing the off-road vehicle to lose the drag of external force and slide down the slope. The throttle has been stepped on to the end, the speed has reached the peak of 8,000 rpm, and the engine is like an old cow that is still breathing, coughing violently, poof, and the tail is intermittently spewing out thick black smoke, as if it will not be able to hold it in the next moment. And Xu Qiang's whole body was already sweating like rain, and the steering wheel was slippery, so he could only hold on to the intersection of the two transverse spokes and the rim.

The last five meters are like a moat.
