Xu Qiang quickly started the car, then turned around and chased in the direction where the wolf had fled. On the way, Xu Qiang explained to the fat man how to get through the valley, which was to use the fleeing black-backed brown wolf.

The appearance of these three black-backed brown wolves was very abrupt, in the vast space to the north of the valley, there were really few living creatures, especially on the ground there was not even a single animal, and the appearance of the red-eyed giant eagle was an accidental and inevitable difficulty, because they were birds, they could fly, and sooner or later they would fly here.

But the presence of the black-backed brown wolf here confirmed their previous judgment even more certainly: they would be able to escape from this barren land immediately. Running in the direction of the giant eagle was roughly expected, and the direction in which the wolf fled was more likely to lead the two of them to find a suitable place for the wolves to live, and this place should also be suitable for Xu Qiang and the two to survive.

Then the cause of the morning fog is analyzed, the conditions for the formation of fog are cooling, humidification, and condensation nuclei to increase the water vapor content, and one of the key factors is that the water vapor content in the air must reach a certain level. Previously, the area they belonged to was a scorched earth formed by the fire, and the air had a low level of water vapor. It is only in close proximity to water-rich areas that the water vapour content in the air can increase enough to form fog. Therefore, from this aspect, it can also be judged that the two of them are about to arrive in an area suitable for survival.

"And how far are we from that area?" After hearing the reason explained by Xu Qiang, the fat man asked.

"How far we are from that area depends on the black-backed brown wolf that is fleeing ahead. But it can also be roughly extrapolated. The wolf's range is about 160-350 square kilometers, which translates to a distance of about 10-20 kilometers in a straight line. So, as long as the two of us can get to the other side of the valley, then we have a very good chance of finding a suitable area to live. So, let's pick up the speed and catch up with that black-backed brown wolf. ”

The wounded head wolf was running slower and slower, because he had been running, and the blood on his thighs had no tendency to coagulate, and the blood sprinkled was as eye-catching as a piece of black wood on the white snow field in the eyes of Xu Qiang and the fat man. After sprinting with all his strength for a while, the figure of the head wolf can already be seen.

"See, it can't run away." The excited voice of the fat man who was in charge of observation sounded, but he was not happy for long, and the figure of the head wolf disappeared behind a stone in a flash.

Xu Qiang quickly rushed to the place where the head wolf disappeared, looked down, and a surprising picture appeared in front of the two. A gentle downward slope is covered with large and small stones, as well as shallow or deep earth pits. And the figure of the black-backed brown wolf also appeared in sight again, running upward.

Xu Qiang got out of the car and observed the slope situation, the slope is very steep, and the maximum climbing degree is about 80% or more close to 90%. If you climb from the bottom of the slope, if there are obstacles, you will probably not succeed, and the probability of car crash and death is very high. But from top to bottom, the relative certainty is still relatively large, as long as the body is not parallel to the slope. And those obstacles don't play too much of a hindrance role, and the benefits outweigh the disadvantages. After weighing it repeatedly, Xu Qiang decided to take advantage of the good weather and wide vision to immediately go downhill. The fat man acted as a temporary observer, helping Xu Qiang to inspect the road conditions in front of the car and guide the direction.

At this moment, it truly reflects the powerful ability of a four-wheel drive off-road vehicle in extreme road conditions. The particularly heightened chassis has good passing performance, and the four red cylinders make the shock absorption effect just right, even through some deep pits, people will not feel too much bumps in the car; Four AT off-road tires provide good road adhesion and enhanced grip; In the four-wheel drive mode, the vehicle provides better power, traction and better driving experience, and the vehicle and personnel are safer and more stable in the case of intense driving, especially the situation that Xu Qiang and the two are currently encountering, and the off-road and safety performance is better reflected. What Xu Qiang has to do is to try to control the speed of the car and try his best to keep the front of the car facing downwards to avoid causing the body to roll sideways.

Xu Qiang drove the pickup truck and slowly slid forward with the idle speed of first gear, only slightly increasing the speed when going around obstacles to make the body straighten as soon as possible. Although I have participated in many off-road activities and rushed through Haohan Slope, it was carried out under the condition of full logistics support, and there were many riders in the back, and problems could be quickly treated. But here, Xu Qiang must remain 120% cautious and not make the slightest mistake.

It was because he was sweating all over his body while driving, the steering wheel was slipped, and he had to wear cotton gloves in the storage box to get better; His right leg spasmed due to staying in one position for a long time, and he had to stop and rest for more than ten minutes. And Luo Fatzi also gave full play to the role of an observer, informing Xu Qiang of the dangers and obstacles he was about to encounter on the way in advance

In the end, under Xu Qiang's full control and the strong traffic capacity of the off-road pickup truck, the two finally drove the car to the bottom without danger. didn't care about resting, and accelerated again to chase in the direction where the head wolf fled, and the two in the middle just drank a few sips of water to replenish the lost water.

The howl of a wolf was heard in the distance, long but abruptly stopped, full of pain, reluctance, and relief. Following the trail of blood left by the head wolf, he went all the way and did not go far, and saw the sturdy head wolf lying on a rock, motionless, as if asleep. And there are some obvious crawling traces behind it, but there are no traces of blood left, obviously this black-backed brown wolf died of blood.

Looking at the scene in front of them, Xu Qiang and the two were speechless for a long time, and then silently got out of the car and walked to the wolf's corpse. Although they were in a hostile position, the two were touched by the wolf's persistence and indomitable spirit. The strength of the three wolves is tantamount to disaster for two unarmed humans, but it is negligent in advanced weapons that are far from belonging to the current era, and it is hated by it. Nature is also so cruel, no one can escape the law of the jungle, and if you are not careful, you may become the ghost of other species.

Looking at the direction in which the wolf was crawling, it was clear that its way back was not far ahead. The fat man carried the wolf's corpse into the trunk and gathered with its two brothers, and they would also become the materials for Xu Qiang and his survival in this world, not only meat, but also fur. During the last Xiaoice period on Earth, the species that disappeared included not only the vast majority of animals and plants, but also most of the soul-leading humans. In addition to food and water, how to survive the long-term ice, snow and cold has become the key to their long-term survival.
