The attack came extremely suddenly, and the opponent's weapon was something that had never been seen before, a lieutenant officer whose strength had reached the third level of the white star directly burst his head, and the headless corpse ran forward two steps, and then fell to the ground with a bang.

"Stealth, fight back!" When Hong Yi saw this scene, he also knew that the combat robot was not a combat robot of the military department at all, so he immediately ordered.

The soldiers behind him were also tested-and-tested, and when they heard the order, they immediately looked for cover and began to shoot at the battle robot that rushed towards them.

Under closer inspection, this combat robot is actually not the same as the combat robot of the military department, although it is similar in appearance, but the difference is still very large, its power system does not have that kind of circuit and oil pipe connection, just simple metal spliced together, there are extremely strange lines on it, and in those lines, there is a faint halo. The robot's only weapon is a laser cannon that looks like a power plant on its back, and it has some kind of strange oval weapon mounted on its hand.

At this moment, bullets are being fired outwards from this weapon at a very fast speed.

In terms of power and appearance, this weapon also resembles a pulse rifle.

Although there were more than 30 people on Hong Yi's side, they were so overwhelmed by this robot that they couldn't raise their heads at the moment. In short, the firepower is too fierce, especially the laser cannon on the other side's back, it is simply an indestructible weapon, even hiding behind a metal barrier, that weapon can cut through the metal wall like cheese.

On the contrary, the bullets of the pulse rifle hit it, and it did not cause much damage.

From this alone, Hong Yi could see that the metal material used to make this strange robot was definitely not ordinary, and its hardness was harder than all the metals he had ever seen.

At this time, two more soldiers were shot by this robot, and then look, the bunker where Wen Jin and the other three soldiers were hiding was about to be shattered by the combat robot, and the situation was extremely dangerous. Hong Yi knew that it would not work if it continued like this, and the pulse rifle would not work, so he would change his weapon.

Hong Yi tossed the pulse rifle aside. Then he took out the Night Blade from the small bag.

The next moment, Hong Yi rushed out, and the combat robot reacted extremely quickly, and the laser muzzle was immediately aimed at Hong Yi. However, at this time, Hong Yi raised his hand and waved his hand and performed the skill of 'flying sand and stones'.

This skill is not lethal at this stage, at most it will knock the target into the air or roll it up, but Hong Yi didn't think about using this trick to kill the combat robot. All he had to do was interfere with the other party's aiming.

A gust of wind rose from the bottom, and the combat robot was violently rolled up two meters high, and the laser cannon that was originally aimed at Hong Yi also lost its accuracy at this time, and a beam of light shot out, grazing Hong Yi's body for half a meter.

Hong Yi increased his speed violently, and rushed to the side of the battle robot in the blink of an eye, and the night blade in his hand was already stabbing out.

Syllable!

With a crisp sound, the Night Blade only pierced about two inches before it was blocked by the metal.

Hong Yi also frowned, all the time. The blades of the night are invincible, even if they are alloys, the blades of the night can easily cut and pierce, I didn't expect the body of this combat robot to be so hard.

The next moment, Hong Yi dodged a sweep of the combat robot, turned around, and had already replaced the sword of the battle robot in his hand, with the power of the turn, the sword of the town stone slashed at the waist of the battle robot, Hong Yi thought that this attack would not have much effect, but he didn't expect that this time it would be a battle robot cut into two pieces.

And that's not all. The destructive power brought by the sword of the town stone smashed half of the body of this combat robot to pieces, and with a bang, the combat robot fell to the ground. Motionless, the special aura in the metal pattern also disappeared, as if it had been absorbed by the Sword of the Stone Suppression.

Hong Yi was also stunned at this time, he didn't expect this combat robot that seemed to him to be very difficult to be killed so easily.

Looking at the Sword of Zhenshi in his hand, and then at the remains of the combat robot that had been shattered on the ground, Hong Yi knew that all this must have something to do with the Sword of Zhenshi.

Hong Yi was a little stunned here. Over there, Wen Jin and Jiao Yong had already surrounded the rest of the soldiers.

At this time, they didn't say anything, but there was a trace of awe in their eyes when they looked at Hong Yi, they could see clearly just now that the shell of the combat robot was extremely hard, and even the pulse rifle could not penetrate it, but they didn't expect to be cut to the ground by Hong Yi with a sword.

What they couldn't understand the most was where did Hong Yi's sword come from?

Although they had doubts in their hearts, these soldiers were trained, knew the rules of secrecy, and knew about the affairs of the commander, and they could not ask if the commander did not say it.

So even though they were puzzled and curious, no one asked. Seeing this, Hong Yi also nodded secretly, if these soldiers asked, it would be really difficult for him to answer, and now they don't ask, it is the best, and it saves a lot of things.

However, Hong Yi knows that it is best not to let too many people know about this kind of thing, especially the fact that he has special storage items such as small Qiankun bags and treasure demon bags, it is best not to leak them, otherwise it will definitely cause trouble.

"Jiao Yong, immediately bring ten soldiers on alert, and the others, collect the wreckage of this robot!" Hong Yi ordered at this time, and the other soldiers immediately executed.

As soon as that lieutenant died, Hong Yi was now the highest-ranking officer on the scene, so these people could only obey Hong Yi's orders. On the other hand, Hong Yi showed strong combat effectiveness just now, which is also the reason why the soldiers are respectful.

The soldier in charge of the guard immediately climbed to the high point and began to look around, while the others followed Hong Yi to check the wreckage of the robot.

Du Yuanyuan bent down at this time to look at the severed part of the robot, and her face was also turned out with a trace of horror, she also shot this combat robot with a pulse rifle just now, but the bullet could not break through the outer defensive shell at all, and at this moment, the seemingly hard metal turned out to be very fragile, she herself is also a white star level evolutionary, the strength is much greater than ordinary people, and the use case can crush these metals with a pinch.

At first, she thought it was an accident, but she tried other parts, and the same was true.

The situation was immediately reported to Hong Yi.

Hong Yi didn't bother to put the sword of Zhenshi into the treasure demon pocket at this time, he knew that there would definitely be a battle next, so it was better to carry it on his back, otherwise it would be very troublesome to take it and collect it.

Hearing what Du Yuanyuan said, he also attached great importance to it, and checked it to see if it was so. The original hard robot body has become very fragile at the moment, and those metals will be crushed as long as they exert a little force.

"It's not metal!"

Finally, Hong Yi came to a conclusion, and when he heard this conclusion, several other soldiers also looked ugly and incredulous. They had strafed this robot together just now, and the pulse bullets couldn't destroy it, so they knew how hard its body was, and now, how could it be so fragile.

No one knows what's going on.

Hong Yi thought of a possibility at this time, there were many lines on the body of this robot before, and this kind of texture can be said to exist on every part of it, and in those lines, there was a strange light flashing, but after he cut off the robot, the halo disappeared.

Isn't it understandable that those halos are the key?

The more Hong Yi thought about it, the more he felt that there was such a possibility, but now he couldn't see the shadow of that halo at all, Hong Yi knew better than anyone that the halo in the robot's body just now was absorbed by the Sword of Zhenshi.

Touching the sword of Zhenshi behind him at the moment, Hong Yi didn't know what to say, so he asked Nuwa, and this time Nuwa's answer was very sure that she didn't know.

I have no choice but to put this matter down first.

But the wreckage of this robot was still collected by Hong Yi's order, maybe it was brought back and studied by the research institute of the military department, and new discoveries could be made.

Of course, the most valuable of all are the two weapons used by the robot, one is the odd oval gun on the arm, and the other is the laser cannon mounted on its back.

Especially the laser cannon, Hong Yi studied it carefully and found that he couldn't use it at all, not to mention himself, even other people were the same, they didn't know how to activate the shooting at all, so although he knew that this laser cannon was extremely powerful, he could only put it away and hand it over to the military department for further research when he went back.

At this time, the soldier in charge of the guard sent back a message that there was an object approaching two kilometers away, and it seemed that it was the same combat robot.

As soon as Hong Yi asked about the number, he immediately ordered everyone to evacuate.

The number of combat robots that appeared this time was as high as ten, and thinking of their terrifying combat power, Hong Yi naturally wanted to avoid the edge for the time being.

After a few kilometers, Hong Yi found that everything here was made of metal, like a mechanical city spliced out of metal.

There are also buildings in this mechanical city, and there are many wrecks of unknown things, but everything is dead and I don't know how long it has been abandoned, and the ground has accumulated a thick layer of ash the size of a fingernail, and there is a clattering sound when you step on it.

Along the way, Hong Yi saw a lot of familiar things, such as combat robots, such as the prototype of a pulse rifle, and some orbital laser cannons that have been destroyed, and even some sophisticated mechanical and electronic equipment.

Although these things look very different, they have a lot in common with the technological devices used by humans today.

When Hong Yi saw this, he already understood in his heart what was the source of the rapid development of science and technology of mankind after the catastrophe. (To be continued.) )
