"Don't speed, don't turn around, don't fire. Ｘ”

This is a warning!

Everyone on the battleship was shocked, and pondered the meaning of this sentence repeatedly, but there was too little information, and everyone was confused, and they couldn't think of the reason after racking their brains, and they discussed it for a long time without a conclusion. The only thing that is certain is that the words made of these stones should have been left by the expedition ship personnel who sent the message for help, but what about them?

After a few minutes of silence, Zhuang Xiaolin ordered: "Search around, maybe there are clues." ”

The operator immediately took control of the lens of the reconnaissance satellite and scanned the plain where the text was located several times, but found nothing. The terrain on this planet is homogeneous, with most of the surface made up of rocks and dark soil, and it is almost impossible to discern useful information from reconnaissance satellites when viewed from above.

"Put the drone down." Zhuang Xiaolin said again.

A drone, just over three meters long, ejected from the battleship's hangar and landed at an extremely high initial speed towards the plain, which soon reached Mach 15, and the on-board camera transmitted the real-time footage back to the battleship.

The plain is located in the equatorial region of the planet, a few minutes later, the drone is only more than 30 kilometers from the ground, the text on the plain is clearly visible, and a large number of messy traces can be vaguely seen next to the boulder that makes up the text, the drone pilot was about to slow down and approach the text, suddenly the screen went black, and the video signal was interrupted.

"What's the situation?" Everyone asked.

The pilot was also at a loss, shook his head and said, "I don't know, the whole plane is lost." ”

At this time, the reconnaissance satellite switched the screen to the screen in time to play back the scene of the drone landing. One second, the drone flew as usual, but in the next second, the drone in high-speed flight suddenly disappeared. The satellite put the picture back many times in a row, but unfortunately the distance was too far, and the satellite did not focus on the drone, so the shooting was not very clear.

Everyone was furious and couldn't understand what was going on.

Zhuang Xiaolin said decisively: "Put another drone out, this time let the satellite lock." ”

"Yes."

Another drone immediately ejected, and it didn't take long for it to reach the sky over the plain. In full view of everyone, the drone repeated the mistakes of the past and also disappeared from the screen. However, this time the reconnaissance satellite took pictures very clearly, and at the moment before the drone disappeared, a red ray appeared out of thin air and hit the drone with great accuracy.

This ray looks very ordinary, similar to a laser, less than five centimeters in diameter, and the time it appears is also extremely short, only lasting about a tenth of a second, and it disappears in a flash, but the power is extremely terrifying, instantly penetrating the titanium alloy shell of the drone and vaporizing the entire aircraft.

Everyone looked at each other in shock, and there was only one thought in their minds: "Where did this laser ray come from?" Where did it go again? ”

The reconnaissance satellite did not find out where it came from, and after destroying the drone, it did not continue to fly forward, but disappeared as if it had escaped into the void.

The laser ray itself is not scary, it is scary that it comes and goes without a trace, appears out of thin air, and disappears out of thin air.

Also, what are the conditions under which the laser rays are triggered? Is this a ban on all flying machines landing on planets? Is it a mysterious weapon left behind by a super civilization? And what is the technical principle?

One question after another followed, the atmosphere on the battleship became more and more strange, and in the face of incomprehensible things, many people quietly retreated in their hearts.

Zhuang Xiaolin fell into deep thought, and after a while, he suddenly asked out loud, "How many drones do we have?" ”

The pilot inquired about the weapons reserves on the battleship and replied: "Twelve." ”

"Keep put." Zhuang Xiaolin issued an order, and seeing the doubts on everyone's faces, he said again: "You have to slow down the speed of the drone this time, don't land at such a fast speed again." ”

After listening to Zhuang Xiaolin's words, many people with flexible thinking guessed his thoughts.

The pilot, although he did not understand it very well, did it anyway. The third drone was released, landing from space at a speed of Mach 1, and it took more than an hour to get close to the ground, everyone's eyes were glued to the screen, and the drone passed the previous two disappeared unharmed, this time, the laser ray did not appear.

"I see!"

One of the mercenaries exclaimed excitedly: "The phrase 'don't overdrive' means don't fly too fast, otherwise it will trigger a laser ray attack!" ”

In fact, there is no need for him to say, seeing that the drone is safe, everyone understands.

The pilot controlled the drone to cruise over the plains at Mach 1 speed, first transmitting the situation of the eight characters on the ground back to the battleship, and then expanding the search range around the words in an attempt to find traces of humans. But after searching for a long time, the stone text has been analyzed over and over again, but there is still no result.

There are indeed a lot of messy traces around the text, all of which are a messy pile of stones scattered randomly, occasionally mixed with a few human footprints, and at a glance you can tell that they were stepped on in power armor, and it seems that a very fierce battle has occurred.

The drone tried to get closer and dropped a bit, only to have another accident, and the plane lost control and crashed to the ground, turning into a pile of scrap metal in the blink of an eye.

"What's going on?" Everyone looked at each other.

The pilot checked the data and quickly found out the reason, reporting: "After the drone flew at an altitude of less than 300 meters, the electromagnetic signal was interfered with, so the control was interrupted." ”

Zhuang Xiaolin thought for a moment and waved his hand: "Put another one down." ”

In the next few hours, at the cost of six drones, it was finally discovered that there is a peculiar shielding force field on the surface of the planet, which can interfere with the transmission of electromagnetic waves, covering the whole world without dead ends, and all aircraft flying at an altitude of less than 300 meters can no longer communicate with the outside world.

At the same time, the upper limit of the speed at which the laser ray is triggered was also measured, which is about Mach 7. As long as the speed does not exceed Mach 7, that mysterious laser ray will not appear.

And then there is no other useful information.

After several days of continuous searching, except for the eight stone characters, the reconnaissance satellite did not find any other anomalies, let alone artificial structures, or even no signs of life.

During this period, the hearts of the battleship were fluctuating, and in the face of such a strange planet, some mercenaries secretly showed their intention to retreat. Although no one said it openly, the rumors inevitably spread and gained the support of many people. This made Zhuang Xiaolin very unhappy, but he couldn't have a seizure, he had an ugly face all day long, and the mercenaries were cautious in front of him, and they didn't even dare to come out.

Xin Xiaolin, who had not participated in the discussion, continued to pay attention to Zhuang Xiaolin, knowing that he had never thought of leaving empty-handed at all.

In fact, most of the mercenaries, including the two deputy commanders, supported Zhuang Xiaolin, and everyone risked their lives to cross more than a thousand light years and run to the hinterland of the Steelmane Empire, but when it came to the end, they fled without even landing on the planet, no matter who they were, they would be very unwilling.

There is also the sentence "don't turn around" that also makes people's hearts heavy, faintly pointing to the meaning of not turning around on the battleship. Until these three "don't" warnings are understood, no one dares to turn around easily.

But to figure it all out, it is inevitable to land on a planet.

Finally, after hesitating for a few days, Zhuang Xiaolin gathered everyone on the battleship and announced that he was ready to land on the planet.

"Here's a list of people who landed this time, and if anyone doesn't want to go, they can come up now."

A holographic screen unfolded in front of everyone's eyes, listing sixty names on it, all of whom were the strongest group of people in the Tyrant Tiger Mercenary Group, and Xin Lin was among them.

Xin Xiao was not surprised by this, he knew it not long ago when Zhuang Xiaolin and the two deputy heads of the regiment discussed the registration list.

At present, there are more than 500 people on the warship, one-third of whom are logistics personnel, and their role in the mercenary group is to serve, including responsible for food, medical care, warship operation and maintenance, weapon maintenance, etc., and the remaining more than 300 people are full-time combatants.

The situation on this planet was too weird, Zhuang Xiaolin didn't dare to send all the combat mercenaries down at once, and decided to draw the strongest group of people and divide them into two landing planes and set off.

Xin Lin had just joined the mercenary group, but his strength was obvious to all, judging by Raven Drake's eyesight, Xin Lone's strength was enough to rank among the top twenty of the mercenary group, so he was put on the list. This is the first time Zhuang Xiaolin has officially learned of Xin Lian's existence, if it were in the past, he would definitely call this Shi Hongyi to get acquainted, but forget it for now, since Raven respected him so much, he had no objection.

To be honest, Xin Lin refused to land on a planet in his heart.

However, after seeing Zhuang Xiaolin announce the list, a dangerous light flashed in his eyes, and he was very aware of the current affairs and did not make a sound. But some people don't know what the situation is like at this time.

"Commander, can I not go?" A middle-aged mercenary asked.

Everyone looked at the middle-aged mercenary, his face showed a little shame, and he explained in a low voice: "My son was just born before leaving, and I don't want to die here and let him lose his father......"

Zhuang Xiaolin's face was expressionless, and before the middle-aged mercenary finished speaking, he suddenly punched out of thin air.

Bang!

The red light shone, and a blazing fist wind hit the middle-aged mercenary in the crowd in the air, knocking him into the air, slamming into the metal wall of the battleship, breaking the bones of his body into an unknown number of pieces, and he passed out before he landed.

"Take him down and lock him up, don't let him die, go back to Space City and ask his family to pay a ransom of 10 million before throwing him off the ship." Zhuang Xiaolin said coldly.

Seeing the middle-aged mercenary being carried out, everyone was silent.

There were also a few mercenaries who originally wanted to withdraw from the landing list, seeing such an end, where did they dare to speak, and quickly closed their mouths honestly.

Xin Xiao shook his head secretly, Zhuang Xiaolin is killing chickens and monkeys, so that those mercenaries who are reluctant to retreat know who is the boss on the battleship, and he has put out the idea of leaving as soon as possible.

From this punch, Zhuang Xiaolin showed terrifying power.

That middle-aged mercenary is a high-level warrior who has cultivated to the limit of the node, and his strength is quite good, otherwise he would not have been selected into the list, but he couldn't catch Zhuang Xiaolin's punch, the difference in strength between the two sides is too big, like a moat that is insurmountable.

Xin Lin thought to himself that he had changed himself, and without putting on an iron-blooded warrior, he couldn't block a few punches from Zhuang Xiaolin.

"If you want to secretly attack Zhuang Xiaolin, you must act cautiously and think long-term." His face was silent, but his heart was thinking about it repeatedly.

Zhuang Xiaolin's gaze swept over the mercenary, and he said in a deep voice, "Does anyone still want to quit?" ”

There was silence on the deck.

"Good." Zhuang Xiaolin nodded with satisfaction and ordered, "Then put on the armor and set off." ”

The remaining fifty-nine people on the list, plus Zhuang Xiaolin and Raven Drake, all rushed to the battleship's equipment bay, where sixty-one pairs of power armor had been prepared and placed next to the wearing machinery. The Tyrant Tiger Mercenary Regiment has more than 200 sets of power armor in reserve on its warships, most of which are standard and mass-produced ordinary armor, called the Dreadnought series.

The price of a set of dreadnought armor is about 70 million, which is considered a bargain, neither protection nor firepower is very outstanding, and the performance can only be at the bottom of the many armors of the Federation.

Even if the Dreadnought's performance is mediocre, this is power armor that can greatly increase the mercenaries' chances of survival.

Ten armor wearing machinery started at the same time, the mercenaries took off their coats, one by one walked up, the armor was quickly installed, in less than a minute, a set of blue and white armor was completely worn on the body, and the sound of mechanical transmission was made between walking, and the armor brought an inexplicable sense of security, so that everyone had more confidence in their hearts.

Xin Lin also put on a set of dreadnought armor, he adapted to it casually, and the experience of using it was more than a notch worse than that of the iron-blooded general.

After putting on their armor, choosing their weapons, and bringing a batch of ammunition, potions, and nutrient solutions, everyone went to the hangar and sat in the two landing planes.

Zhuang Xiaolin and Raven each led a landing plane, and Xin Lin was assigned to Raven's side, and he noticed that Raven's armor was different from that of the mercenaries, wearing a set of backfire armor worth more than 300 million, and his performance was much higher than that of the dreadnought. On another landing plane, Zhuang Xiao was also wearing silver and white backfire armor.

Having sat down, the landing aircraft flew out of the hangar and broke away from the battleship.

The landing site was chosen on the plain where the stone text was located, near the equator, because the flight speed exceeded Mach 7 would trigger the laser rays, and for safety reasons, the landing aircraft only flew and landed at Mach 3 speed.

Sitting in the cabin, the silent telepathy swept over the people, including Raven, all the mercenaries were solemn, and some of them looked at the nebula outside the string window, or kept wiping their weapons and checking their armor, and the words in their mouths revealed the uneasiness in their hearts.

Xin Lian's heart was also very heavy, and that feeling of danger always lingered in his mind, like a bone appendage, lingering.

After flying in silence for more than forty minutes, the landing aircraft was close to the ground.

When the altitude below the ground is less than 300 meters, the signal of the optical brain inside the armor is interrupted, the network connection is lost, and the communication channel established between the mercenaries is also invalid.

However, this was expected and did not cause panic among everyone.

Before landing, the landing aircraft was changed to manual piloting, which could operate as usual, and after a few seconds, with a slight shock, it landed on the ground. The hatch immediately opened, and the armored mercenaries rushed out, stepped on the surface of the planet, and quickly formed a defensive formation with weapons in hand, guarding the surroundings.

Zhuang Xiaolin took the lead, turned his head to look at the stone text not far away, confirmed that there was no danger, and said, "You withdraw the battleship first." ”

The two mercenaries piloting the landing plane should have said in unison, their strength was average, and they didn't dare to stay on the planet for a long time, so they hurriedly took off.

The landing planes took off one after the other and slowly accelerated into the air.

At this time, Xin Xiao was looking at the stone in front of him, the last two words were "turn around", a flash of inspiration flashed in his mind, and at the same time there was a palpitation, and he said secretly: "No! ”

Before the thought fell, out of the corner of his eye, he noticed two thick red lights flashing, and the two landing planes that had just taken off for a few seconds made a muffled sound, and the weapons and ammunition in the cabin were triggered, and they exploded violently, turning into two huge fireballs scattered down.

The mercenaries on the ground scrambled to dodge the blast wave from the explosion.

Fortunately, the landing plane exploded in the air at a distance of more than 100 meters, and did not cause much damage to the mercenaries.

Zhuang Xiaolin gritted his teeth and said: "It turns out that 'don't turn around' means that you are not allowed to leave. ”r
