When Wang Xu drove to follow Mu Tianyu's car over the valley bottom, he almost completed several difficult tests in climbing. Although Wang Xu was in a backward position in the initial hill climbing competition, it did not affect his mood.

Next, Mu Tianyu drove the car into the rocky hill in front.

The ground was full of pebbles, the big ones the size of a military cauldron, and the small ones the size of a man's fist.

From afar, this place must have been a riverbed a long time ago.

The cobblestones may have been caused by historical floods, mudslides. But the specific cause should be traced back to the Mesozoic era about 100 million years ago.

Under the action of the earth's crustal movement, magma emerges from the surface, and granite is formed by quickly obtaining cooled magma. Thousands of years ago, the staggered extrusion of granite caused by magma intrusion produced a large number of smaller stones, and those stones at the water's edge were slowly washed away by water and rolled by themselves over a long period of time, and finally formed today's pebbles.

In this area, some rocks may have not had time to be weathered into pebbles, and the riverbed here has completely dried up; Some stones are rounded after weathering and become pebbles.

It is not a problem for a normal off-road vehicle to pass through rocky obstacles, but gravel is prone to cause strong bumps.

Pebbles, in particular, are fluid, and cars are advanced above and are prone to skidding.

When driving in rocks, you should also be extra careful because angular stones are more dangerous. Not only can they puncture the tire, but they can also cut holes in the sidewall on both sides.

Mu Tianyu passes at a slower speed, which can greatly reduce the risk of the tire being scratched, so as to ensure absolute passing safety.

But Wang Xu didn't think so, he just wanted to win at this time.

He quickly chased after him and shouted over the walkie-talkie: "Master, why can't you turn on, crawling so slowly!" ”

"Take care to protect your tires." Mu Tianyu seemed to give an order, and it seemed to be telling Wang Xu to know.

But Wang Xu said: "This kind of place must have been a riverbed a long time ago, and after it dried up, it formed a rocky hill. In the past, pebbles were formed by the impact of water currents, but now they are mainly formed by weathering. ”

"Drive well," although Mu Tianyu knew that what Wang Xu said was right, and also knew the meaning of his analysis, the conclusion was: The stones here are not sharp enough to scratch and puncture the tires.

"Be careful, there may be fixed stones of different shapes underneath the pebbles."

As he was talking, the rear wheel of Mu Tianyu's car began to slip. Maybe it's because it's too slow, causing the right rear wheel to sag when it slips, and the left rear wheel to start skidding as well.

Wang Xu took the opportunity to overtake Mu Tianyu from the side, maintained a certain speed, staggered, violently bumped, and quickly passed through the chaotic stone hill.

Mu Tianyu could only get out of the car and began to move a few large stones that were not too round and stuffed them under the rear wheels.

He boarded the car again, and when he reversed, some of the larger stones fell into the wheel pit. Mu Tianyu changed to the forward second gear, stepped on, and rushed out.

He also accelerated the speed of the car a little like Wang Xu, and was no longer so careful and slow.

The jeep was very bumpy and staggering, and it drove out of the rocky hill.

When leaving the rocks, Mu Tianyu got out of the car again and carefully checked the condition of all the tires.

Because Mu Tianyu felt that after the car waited for the end of the race, and drove at high speed on the highway, a small crack on the tire was easy to cause a puncture, and the consequences were serious.

And Wang Xu didn't think about it at all, he drove the car directly onto a downhill in front.

Mu Tianyu understood Wang Xu's mood, looked at his advancing jeep, and thought that it was better to fight steadily and steadily, not to damage the vehicle because of the ruthlessness.

In fact, the downhill is like climbing, and where Wang Xu drives in, he almost must use a low-specific gear group and a low gear.

But Wang Xu still used 3 gears. This is through a road-like extreme gear.

At this point, the engine braking efficiency should be used as much as possible. Jeeps' downhill deceleration systems are generally designed specifically for this type of terrain.

However, in the process, generally do not step on the brake plate, should keep a straight downhill, strong braking may lock the vehicle, will make the steering function temporarily invalid, if not straight downhill, may be due to the slope is too awkward, so that the car overturned, very dangerous.

Mu Tianyu looked at Wang Xu's posture, he was fighting for his life. I thought to myself, this exercise training, although the addition of this racing car can be regarded as adding luster to the entire exercise training subject. However, it cannot show the strength of the entire rescue brigade, nor can it train all the commanders and fighters, and it is a relatively niche exhibition game.

Therefore, Mu Tianyu didn't want to damage military materials because of Wang Xu's gamble. These two jeeps are also relatively new and important equipment of the Jiangcheng Fire Detachment.

The two captains don't see it that way. They believe that in the course of the exercise, all the problems that occur, especially the unexpected, are likely to suddenly appear in different ways in actual combat.

They wanted to take this opportunity to practice Mu Tianyu as well. Everyone knows that Mu Tianyu, who is just 28 years old, has already written an invincible military myth.

But a person always has a specialty that he is not good at, that is, as the saying goes, "there is a specialization in the art industry." "When it comes to racing, Wang Xu is a professional. He also has a very strong appeal, and he has a group of brothers around him.

His ability in this area may be what Mu Tianyu needs.

Fortunately, this Wang Xu has his father's genes and can make good use of people. He is bent on making a friend of Mu Tianyu, and he wants to be friends with Mu Tianyu for life, regardless of fame and fortune.

Although his way of establishing a relationship with Mu Tianyu is very strange, his sincerity, the two captains especially understand.

They felt that Wang Xu was suitable for a soldier, and if he could be with Mu Tianyu, maybe their cooperation would complement each other and be conducive to promoting the development of the army's affairs.

At the same time, they can also explain to the old leader, Wang Xu is carried by Mu Tianyu, his energy will be used in a serious place, and he will progress and grow.

And Mu Tianyu will also have one more channel in his work.

However, Mu Tianyu didn't think about this at this time, he just wanted to win Wang Xu and no longer be "harassed" by his tracking; If you can't win, it's a big deal that Wang Xu needs him to help him, and if he wants to learn the technology or knowledge of firefighting, he will pass it on to him without reservation.

He keeps calling himself master, so isn't that what the master has to do!

Of course, he didn't think that when the master modified the world of sports cars, he also had many rules similar to those in the Chinese martial arts world. Every racing team will have such a master, this master, for a team, he is a soul, he can turn decay into magic, he can make this team invincible forever.
