It didn't take long for the physically and mentally exhausted old D and his party to go to the valley under the leadership of the doctor, and when they saw the well-equipped and fully armed Xingfeng and others, they immediately breathed a sigh of relief, and they all couldn't suppress their cheers.

What's more, he just lay on the ground and cried with joy!

"Hahaha, Allah forbid, I am finally saved, thank Allah."

"Gentlemen, thank you, thank you for coming to our rescue."

"Commander, it's great to see you alive, those demons are simply terrifying."

……

For them, these nearly two weeks have been an ordeal from hell.

And the members of the action team who came to the rescue, seeing that this group of big men were forced to be this "crazy look", recalled the description of this torture before, and their hearts suddenly tightened.

I know that the enemy I am about to face is probably not just tricky!

"Scalpel, big man, you're in charge of treating the wounded, motorcyclist, you take over the guard of the scalpel, and the others send food and water down."

Xing Feng gave an order, picked up a bottle of water and a piece of vacuum-packed ham, walked up to Lao D and handed it to him, patted him on the shoulder and said, "Tired, eat something and rest first, do you know where they are now?" ”

Although the old D five-person group is the existence of villains, and the fanged mercenary team has also been adopted by Xingfeng in the mode of "stocking", it does not mean that he does not care about their life and death.

After all, that was in the past, and now they are also their own subordinates, and they are all talents with good combat ability.

Old D, whose face was covered with mud and grass clippings and whose image had been completely ruined, unscrewed the lid and drank most of the bottle, and then directly bit into the ham package.

After taking a bite impatiently, he calmed down and said, "After last night's overnight journey, they should be about twenty to thirty kilometers away from us now, and they will definitely not be able to catch up for a while and a half." ”

"Surely you can't catch up, are you sure?" Seeing that Lao D said it so accurately, Xingfeng was greatly surprised.

"I'm sure, Commander."

Old D swallowed the food in his mouth, and then said: "There seems to be a reason for this, I don't know the specifics, I only know that this group of people wearing metal armor is very fast in the daytime, and we can't outrun them at all, even in this woods." ”

"But once it's night, they stop the pursuit, which is strange, and that's why we've been able to escape so far."

"It's night?" Xing Feng was stunned.

According to the news given by Satan's God before, as well as his own personal experience, Xingfeng is very sure that this group of people must be some organization that has obtained the technology of interstellar civilization.

However, these high-tech gadgets, which are powerless even anti-materiel sniper rifles, have this strange and even incredible flaw.

This was a completely unexpected accident!

"Are these just half-finished products? Or is it an energy problem that hasn't been solved yet? Or are they relying on solar energy? Xing Feng thought to himself.

On the earth now, the auxiliary device of the "individual exoskeleton system" is no longer mysterious.

Although its function is far from the "protective armor" worn by the group of people who chased after it, its fundamental purpose is to serve the soldiers and increase the combat ability of the soldiers.

The reason why the "individual exoskeleton system" is not popularized is that it is still a laboratory product, and the biggest problem is energy.

Until "controlled nuclear fusion" is overcome, or new energy storage devices appear, all existing storage devices on the earth cannot support the actual operation of the "individual exoskeleton system".

The "protective armor" of this group of people is very powerful, and it is inevitable that the energy consumption will be huge.

Of course, this is just Xing Feng's personal speculation, and he doesn't dare to make a conclusion as to whether it is a matter of energy or not.

"How many people are there, what kind of weapons and equipment, and how long will it take for them to catch up with their ability to move during the day? Tell me more about the situation. ”

Why this group of people of unknown origin came out at night and day is inconclusive for the time being, but other information will be of great help to him.

"The roads in the mountains seem to be very restrictive for them, and their speed during the day is about twice as fast as ours, and the speed should be about 6 kilometers per hour, as for how many people ......"

"There were only two people who fought with us at the beginning, but as soon as these two people appeared, we were directly defeated, and seven men died in just half an hour, completely unable to resist, as for the back...... We've all been running away......"

Old D's pupils dilated for a while, and he smiled bitterly with palpitations, and did not continue.

As if it were a nightmare!

Seeing Lao D's appearance, Xing Feng could imagine that when they faced this group of "invulnerable" perverts, they were all stunned, where did they still have the heart to care about others.

"Since you haven't fought again, how do you know how far away they are from you?"

Hearing Xing Feng's doubtful words, Old D showed the first smile that had converged so far.

A little proud!

"Their tracking methods are very strong, no matter how much we run, we can't get rid of them, but the way seems to be very simple, they all follow the path we escaped."

"And when we escaped, in order to create obstacles for their pursuit, the ghost used grenades and rockets, and deliberately arranged a lot of ghost mines along the way, as well as some communication equipment for detection."

"I didn't expect it to be triggered by them, and this distance is what we can judge by the sound of explosions coming from the communicator."

Hearing this, Xing Feng became more and more sure that the reason why the "protective armor" on this group of people was so different in combat ability compared to the one he encountered a year ago, and the difference in combat effectiveness was so big, and even the function of scanning and detection was gone, it should have encountered some bottleneck.

After all, this is the earth, and the materials and technology are very effective, no matter how powerful the technological products of your interstellar civilization are, after they have been used for so long, they will inevitably encounter the problem of energy shortage.

"Okay, it's going to be a few hours before they chase after you, now you take your people to the back to pay attention, and then you have the energy to participate in the battle."

Xingfeng's words startled Old D, and he exclaimed in a tone several degrees: "Commander, are you sure we are not retreating immediately?" ”

This group of people basically ignored bullets and grenades, and even if they were hit by a bazooka, they would only be blown up, and they could get up and fight as usual.

Now Xing Feng didn't choose to retreat, but wanted to organize a wave of people in this valley, which made Old D couldn't believe his ears.
