Just when Chen Xi was thinking about how to use to safely pass through this dead sand, in the other three directions of the base, there were also two teams of participants who made faster progress at the same level.

After an introduction to the program, they also saw the difficulties of this sandy land.

In addition to the two more intuitive questions that Chen Xi thought of, there are several details that must be noted.

First of all, Kunfa is not a purely dead thing, like rugby, it moves.

Although it flies very slowly, it is still moving, and it will still change its inherent direction of movement during the transfer between personnel. The angle of this deflection may be small, but as the passing distance increases, the range of deviation will increase accordingly, until the receiver cannot receive the ball accurately.

Secondly, it is important to consider the problem of someone dying unexpectedly after receiving the ball.

This is the most dangerous stage of the entire playthrough, as once someone is besieged and killed by Guise during the pass, causing Kunfa to stop the transfer, then the whole team faces a serious test of life and death.

The surrounding participants must rush to the location where Kunfa is located in the fastest time to collect and pass it away. Otherwise, the longer the time drags on, the more Giss will gather under Kunfa, and the more dangerous the action to recover Kunfa will inevitably be. Eventually, the location becomes a death trap that consumes the lives of the participants, putting the entire team at risk of destruction.

The above two details limit the distance between the participants, and must not be too long, and must ensure the stability of the relay and the room for timely recovery of mistakes after someone dies, but correspondingly, the shortening of the distance during the relay will be a bad news for the participants in the range, which means that the probability of them being attacked is greatly increased.

This brings us to the third problem, how to grasp the degree at this distance. It not only ensures that the occurrence of mistakes can be minimized, but also reduces the number of times that most participants are attacked by Guiss to a safe range.

It can be said that these five points of the puzzle constitute a source of danger that all participants have to face with caution, and they need to spend a lot of energy on it, otherwise, if any of these problems are not taken into account, the team will be in a desperate situation.

And the place of tragedy is also here, the time limit for oxygen supply in the third level is only a little more than an hour, and the time is passing little by little, leaving them not long to think and arrange.

"That's the real problem we need to face, and when I went to the toilet, I tried the black material that surrounded the field, and found that they are a soft elastic substance with a certain fluidity, and I can't stand the weight of a person hanging on it, and besides, after being attacked, it will recover in a very short time, that is, don't think about avoiding Guise's attack from the road above, we can only pass through the ground in a real way."

After returning, Chen Xi explained all the problems that need to be faced through this sandy land.

Of course, this is not to scare people, but to remind these people that they can see where the danger lies, so that they can avoid the time when they really face it, but they become scrambling because they are not mentally prepared.

"If we look at it this way, even if we can get through this sandy field, we will lose a lot of people."

After hearing this, one of the three Kahneman brothers thought about it, and then said with some worry: "I calculated just now (monocular distance measurement method, the basic skill of artillery, estimate the distance by the thumb and the sight angle of the location, the deviation within ten kilometers is not large), the distance to reach the opposite side is two kilometers long, even if we run with all our strength, it will take us nearly three minutes to fully pass, not to mention that we still have to carry out the team's transmission, at least twice the time." ”

The others looked at each other with the same expression. A few of them had less agility attributes, and they looked over with apprehensive eyes.

Chen Xi understood what they were worried about, and no one here's agility attribute was more than 20 points. According to the calculation method of the Evolution Center, 10 points of agility represents the ultimate speed of humans - about 100 meters in 10 seconds, even if they rely on the amount of force and agility increase brought by the exoskeleton power system contained in the electromagnetic protection armor (10 points each), it is difficult to increase their agility to the extent that they can cope with a large number of Guiss sieges.

They had already felt the speed of Guise's attack when they were in the ruins of the city, and no one here could handle more than four attacks at the same time. Not to mention that in the sandy environment, Gis's movement speed will be increased again, and the frequency of attacks will be higher, while their movement speed will be further reduced due to the loose ground.

For such a long period of time, not only those who hold Kunfa will encounter a large number of attacks, but those who are on the periphery will inevitably face various dangers.

All in all, even the strongest Kolchak did not have much confidence that he would not fall into a desperate situation due to various accidents in the process.

However, Kolchak did not show too much worry like others, but asked directly to Chen Xi, who was currently in charge: "Okay, don't sell it, I don't think you're worried at all, you should have thought of a way to deal with it, no matter what kind of arrangement, as long as you tell it, we will definitely do it." ”

Saying this, Kolchak suddenly turned his head and warned the others with a fierce face: "If anyone has problems in the process because they don't listen to the arrangement, even if they get through this level at the least, the people on my side will definitely not let him go." ”

As a top soldier with actual combat experience, he has already seen that Chen Xi's purpose in explaining the difficulty of this level is to let others clearly understand the danger and let them understand that if they do not listen to the command and arrangement, it will inevitably be the end of the regiment's annihilation. And his warning is to add a layer of insurance here, not to mention that everyone here will become like a machine, and will carry out arbitrary orders exactly at all, but at least to ensure that everyone remains consistent in their actions to the greatest extent.

This is the benefit of having a good teammate, and many things that are inconvenient to say and do can be consciously helped to make up. Of course, the premise is to ensure that the purpose of the two sides is at a high degree of unity, and there will be no phenomenon of pulling each other's back.

Looking at the people whose expressions became solemn, Chen Xi glanced at Kolchak gratefully, and directly followed the topic: "Indeed, as Kolchak said, I have already thought of ways to pass through this sand safely, or three, but the premise of these methods is that you must fully cooperate with my arrangements and instructions. ”

"Remember, it is full cooperation, there can be no deliberate negligence in the process, as long as you can guarantee this premise, I can also 100% guarantee that you will pass this level safely."

Not to mention that the words "three methods" will bring these people a frustrating feeling of "I am too stupid to even think of one", Chen Xi once again emphasized the importance of discipline, and then said all the methods he thought of.

In order to make it clearer, he said as he drew a series of patterns on the ground covered with fine sand for a more detailed explanation.

"The above is my tactical arrangement, if someone doesn't understand, you can ask me, you all know that this is a time race with only two endings, life or death, and a mistake or omission will push us to death, so there can't be any ignorance"
