The group of mercenaries on the plane are actually a little stunned now, they really haven't seen such a fierce guy in the process.

According to their original plan, they pursued along the railway, and after catching up, they landed ahead, and then they managed to climb onto the train and find their target.

But they didn't know that this train would be a special military train, and according to their plan, although it was obviously too late to depart, with the helicopter's speed of more than 200 per hour, it should not take more than an hour to catch up with a train with an average speed of only 50 or 60 per hour.

But they never expected that this train was a military special train, and the speed reached nearly 100 kilometers per hour, and after they barely caught up, they looked at the train that was roaring and speeding below, and with obvious military signs, they had already retreated.

Flying a plane into Mongolian territory was already quite risky, and they would not have dared to do it if it had not been for the fact that the Mongolian borders had been lax and that the Mongolian military had little air defense.

The $30 million bonus, like a blindfolded lard, made them decide to take a risk.

This is also based on the fact that they know enough about trains in Mongolia.

Mongolian passenger cars often carry dozens of carriages, some of which are more than five or six hundred meters long, which makes the strength of the nose limited and the speed of the vehicle extremely slow.

The speed of passenger trains is relatively fast, but it is only a maximum of fifty or sixty.

Freight trains, on the other hand, tend to be slower, especially trains leaving small places like Sukhbaatar Station, which often have fifty or sixty carriages hanging on them, and the speed can be as low as less than 30 kilometers per hour.

You must know that the world record of 100 meters of human beings is close to 40 kilometers per hour, even if ordinary people, who are stronger and faster, within a distance of about 100 meters, it is basically not a problem to reach 25 kilometers per hour.

And this kind of train is so long, it doesn't need the speed that they mercenaries can catch up with the train, they just need to be able to see the right time and climb on the train at the right time.

It's not like they haven't tried something similar before, basically, trains with speeds below forty per hour, and it won't be too difficult for them to climb up. A small number of them are more qualified, and they can barely jump into a car with a speed of more than 40 per hour.

Yes, they originally came to a freight train with a speed that was basically impossible to exceed forty per hour, but they didn't expect that when they caught up, they already felt that something was wrong, and after flying for a short while, the speed data of the train obtained by the pilot reached more than ninety-five, which made the gang on the helicopter basically give up their previous ideas.

And because it was a military train, they didn't have enough explosives on board, so the chances of trying to stop the train or trying to climb on it were already very low.

They had been thinking that maybe they should choose to give up, although the Mongolian military was useless, but they were not bold enough to be ready to wrestle with the Mongolian military in Mongolia.

After all, their base camp is in Russia, and they have long relied on Russia's vast and sparsely populated region, and the Eastern Siberian region is one of the regions with the most lax military control, so they have survived to this day.

In fact, they usually take on missions that are rarely on the Eastern Siberian side, but on the territory of Kazakhstan, as far as the eastern part of the Caspian Sea.

If they really cause any big trouble in Mongolia, the Mongolian army may not have much to do with them, but the Russian military will definitely be able to follow the clues to find their secret base in the territory of the Republic of Buryatia in the Russian Federation.

They know very well that it is not that the Russian military cannot find them and cannot kill them, but that the Russian military is not aware that there is such a mercenary army active within its territory. Because this mercenary army rarely takes on missions in Russia, and if they do, they are all small tasks similar to these few days - of course, when this task is upgraded from just killing a Chinese named Lao Dapeng to killing a Chinese named Cheng Yu worth 30 million dollars, it has become a big task enough to drive them out.

But no matter what, just killing a few people is insignificant on the scene. Even if it is noticed by the Russian military, it is difficult to implicate the entire mercenary army.

But because Cheng Yu ran too unexpectedly, these mercenaries made the decision to use this old-fashioned agricultural military helicopter that they usually didn't dare to use.

They made such a decision, thinking very well, driving the plane out, catching up with Cheng Yu and killing him, and then directly discarding the plane on the vast steppe of Mongolia.

After all, when they got their hands on this plane, it didn't cost a total of more than $100,000. And the market price of a brand-new Mi-8 helicopter is about six million US dollars.

Compared to the $30 million bonus, it's insignificant.

But the unexpected discovery after catching up with the train is enough to calm these guys who have been carried away by bonuses again, and it is not a matter of more money and less money, but something that may lead to a sweep of their bases by the Russian military.

They wanted to give up, but they were a little tormented, after all, the deal had only received an advance payment of $300,000 so far, but it had already taken four lives, and the messy expenses had already exceeded $100,000. Now that they give up, the plane is basically unkempt, which leads to some hesitation.

But just when they hesitated, Cheng Yu jumped out and fired a few shots at the plane like a demonstration, this is an airplane, not a hen, even if you want to eat chicken, you can score clearly, okay?

And those mercenaries on the plane, how could they have been subjected to such an "insult"?

Especially when Cheng Yu left the train alone, and let them see the possibility of completing the mission, as if 30 million dollars began to beckon to them again, therefore, the head of the mercenary didn't care about the pilot's gunshot wound, and even didn't care that guy was the only "baby bump" who could fly an airplane in their entire mercenary army, and still ordered him to endure the gunshot wound and turn the nose of the plane to chase Cheng Yu.

The pilot had been shot before, but now it was a little bit bigger, and after the ejection of the bullet, the shape of the warhead had changed, and after being shot into the body, it was different from the feeling of being directly ingested into the body. But he still endured the pain at the base of his thigh and struggled to control the plane.

He knew very well that it was not a matter of whether he listened to orders or not, but that he had to control the plane well and make it land safely.

Otherwise, it's the entire plane that dies.

And the pursuit of Cheng Yu, after all, is just a broken car that can't run fast on the grassland, which can't add a few minutes.

Enduring the pain, the pilot reversed the direction of the nose of the plane, and the fuselage swayed from side to side, chasing the jeep piloted by Cheng Yu.

At this time, the leader just now had already thrown away the telescope, picked up the assault rifle around his neck, walked to the tail of the plane, and opened the cabin door near the tail of the fuselage.

Although it is also clear that in such an aircraft with very unstable flight, it is extremely difficult to shoot even a car.

However, the humiliation of being almost hit by Cheng Yu just now still made the leader unable to suppress the anger in his heart, and tried to stabilize his body, frantically pouring the bullets from the assault rifle in his hand in the direction of Cheng Yu's car.

Cheng Yu stepped on the accelerator in the car, he also knew that he would not have too much time, and it might be a matter of minutes for the other party to catch up, and he had to drive the car to the river before this time.

The body is uninsured, and it is not known how many people were on the plane, but a rough estimate is that there are at least a dozen.

The firepower of a dozen guns was enough to shoot the car into a sieve.

Only by arriving at the river as soon as possible and using the cover of the riverbed can he reduce the number of opponents as much as possible when the plane lands.

Of course, Cheng Yu still relies on this, after all, with the blessing of firearms.

While driving frantically to the river, Cheng Yu also quickly clicked on the pattern of the system mall in his mind and quickly exchanged for a firearm.

When the exchange was successful, Cheng Yu was slightly stunned, because he had spent eight points on the exchange of firearms this time.

It was only then that he remembered that his firearms had been upgraded because he had accidentally played a doublekill in that woods, and now it was no longer an intermediate firearms, but an advanced firearms.

Correspondingly, its redemption points have also increased a bit.

But after Cheng Yu completed the upgrade of the firearms, he didn't have more time to let him see what kind of changes the upgraded advanced firearms skills had produced.

Immediately turning the picture in his mind into the task pane, Cheng Yu clicked on the advanced firearms that had been successfully exchanged.

A translucent dialog box appeared in Cheng Yu's mind, and he saw that it was written: Do you use firearms immediately?

Of course, Cheng Yu chose whether or not.

Then, just as he had done when he first used the Intermediate Gunnery, a second dialog popped up in the Divine Pick system, which read: Do you want to check the details of the use of the Advanced Gunnery immediately?

This time, Cheng Yu chose "yes".

"The advanced level of firearms can allow users to calmly control people and firearms with a caliber of no more than five centimeters, and the accuracy of the visual range can reach more than 98%.

This firearm is not used by the host himself, but can also be applied to others, and after the host confirms the use of firearms, the host also needs to select the user.

The user must be within the host's visual range.

After use, the user will experience memory lapses, so use with caution.

Once used, the high-level firearms will continue to work on the user until the host's points are depleted.

For each minute of firearms duration, twenty points will be deducted from the host.

If the living target dies, one hundred and fifty points will be added. ”

Sure enough, after the upgrade, the hit rate increased. However, the threshold for its use has also become higher, and the number of points consumed per minute has reached twenty.

Along with this, the number of points you can earn by shooting enemies is also greatly increased. Although the cost does not increase year-on-year, as long as the timing is properly controlled, the gain will be much higher than that of intermediate firearms.
