"Sneer~Sneer~"

With a low cutting sound, the door to the outer floor of the studio was quickly swept away by the assassin piloting the mech.

"Haha, Mr. Zhang, the mecha you built is really easy to use. Black Snake, this craft is much better than yours! The Assassin laughed.

After the gate is gone, a golden-red crystalline titanium alloy defense layer is displayed inside.

"Hey~ There is still a layer, yes, Mr. Zhang, it seems that you have already taken precautions, but this is a futile struggle, look at my means!"

The steel-gray mecha took a few steps back, followed by a violent hissing sound from the mecha engine, and the mecha rushed forward, and the high-energy particle concussion knife in his hand thrust forward with force.

"Broken!"

"Huh~~~~" A piercing metal friction sound appeared, and the tip of the knife scratched the crystalline titanium alloy plate, rubbing a long spark.

This scene looked unusually terrifying, and Ling Xiao subconsciously exclaimed.

However, when the spark was extinguished, the crystalline titanium alloy plate was unharmed, and if you look closely, you can only see a scratch the size of a hair on its surface, and then look at the high-energy particle concussion knife in the mecha's hand, the tip of the knife has been broken, and there is a very obvious curl blade on the knife body.

Obviously, with this concussion knife alone, there was no possibility for this mecha to break through the crystalline titanium alloy wall.

"It's okay, it's okay." Ling Xiao let out a long breath, her whole person relaxed, she turned her head to look at Zhang Yuan: "BOSS, the military will soon find out about the abnormality here, I estimate that it will only take half an hour at most." ”

As long as they survive this time, they will be safe. Judging by the defense of the crystalline titanium alloy, they are now very safe.

Zhang Yuan was not as optimistic as her: "If the military wants to discover the anomaly here, I'm afraid half an hour is not enough." ”

Ling Xiao was stunned: "What do you say?" ”

"Very simple reasoning." Zhang Yuan smiled: "Since this group of assassins can find a way to transfer the signal we sent here to this disguised Colonel Levi, they can naturally disguise our existence in front of the military." We have just finished contacting General Li Delin, and General Li has just called 48 million star coins, according to common sense, we should be busy during this time. General Li will definitely not bother for no reason....... All things considered, we are afraid that we will not be able to wait for assistance today. ”

These words almost brought Ling Xiao's tears down, and her voice took on a crying tone: "BOSS, how long do you think our defensive wall can last?"

"I don't know." Zhang Yuan shook his head, this is the truth, if the other party has been using conventional means, then don't say that it will not be able to break through for 12 hours, 36 hours, but in case the other party has any killer features, it will be difficult to say.

"What then?" Ling Xiao's heart was messy again, and all kinds of thoughts went up and down in her mind, one worried that she would die early, the other worried that Zhang Yuan would really be killed, which would cause the Golden Sky Domain to suffer huge losses, and she was also worried about how her elderly parents would face such a tragedy after her death.

Seeing her so lost and depressed, Zhang Yuan smiled and comforted: "Haha, Miss Ling, don't be so pessimistic. It's not the worst yet, and it's not like we're not out of the cracks. ”

As he spoke, he quickly operated on the holographic screen with both hands, and as he operated, three 3D printers not far away started at the same time and began to run at full speed.

"It's a pity that I sent the mecha at hand to the mecha exchange exhibition hall, otherwise, I wouldn't have any pressure to come to 10 clowns like this outside." Zhang Yuan sighed slightly.

Mecha is a heavy weapon of war, and each mecha has a note, and the only mecha that Zhang Yuan has in hand is the brand new assassin mecha he recently made. It was precisely because the mecha was gone that he was in a dilemma.

However, although the assassin mecha is gone, in this studio, the materials, equipment, and energy are all complete, and as long as there is enough time, he can completely create a weapon to restrain the assassin.

The only question is to see if the other party will give him this time.

The printer was running at high speed, and Zhang Yuan didn't build a mecha, because this thing was too complicated, it would take too long, and the risk was too great, so he built an all-phase sniper artillery.

Compared with mechas, the artillery structure is simple and powerful, as long as the aiming system is powerful enough, there is no problem at all to deal with an elite assassin mecha.

When the 3D printer was running at high speed, the assassin mecha outside the studio door was not idle.

He tried to slash the crystalline titanium alloy layer a few more times, but in vain, he took a few steps back and stood there motionless, and after 3 minutes, he took out a metal ball with a diameter of 15 centimeters from the storage compartment of the mech, the surface of the metal ball was very smooth, but dense lines could be faintly seen.

Zhang Yuan has been paying attention to his movements, and as soon as he saw the metal ball, he immediately enlarged the image, scanned the surface texture of the metal ball, and then entered it into the database of the super light quantum brain for comparison.

A few seconds later, the Optical Quantum Brain gave the result: "There is a 92% chance that this object is a crystalline phase converter." ”

"Oh my God!" Ling Xiao let out a low breath.

Crystalline phase converters can easily change the macroscopic physical properties of matter, for example, crystalline titanium alloy is macroscopic as a high-strength, extremely heat-resistant metal solid, but after using this thing, crystalline titanium alloy may be converted into a soft plasticine-like thing.

"BOSS, this thing is still in the research and development stage, although there are some achievements in the laboratory, but there is still a long way to go before it can be applied. How could this guy possibly have a finished product? ”

Zhang Yuan thought for a moment and said, "There should be a very complete team behind this assassin. This team has very strong scientific research capabilities and very strong mechanical skills. He just mentioned a guy called 'Black Snake', and that guy is supposed to be the core of this support team. ”

At this moment, the Assassin had already installed the phase converter 50 centimeters in front of the crystalline titanium alloy plate, and after installing it, the Assassin mech pressed to start.

After about 2 seconds, the lines on the surface of the crystalline phase conversion instrument lit up one by one, and after 3 seconds, a small circular opening suddenly opened in front of the instrument, which lit up slightly, shooting out an emerald green cone-shaped light.

When this ray of light hits the crystalline titanium alloy plate, something strange happens!

The alloy plate, which was originally tough and flawless, began to become loose, and a large number of small holes like a hornet's nest appeared on the surface, and in each small hole, a large amount of oily liquid like candle oil not only gushed out, but the crystalline titanium alloy plate began to thin at a speed visible to the naked eye.

The main control brain in the studio immediately started to alarm.

"The outer layer of defense has been compromised, and it is currently 92% complete."

"The current completion rate is 85%."

"The current integrity is 76%."

“。。。。。。”

The crystalline titanium defenses are crumbling at an alarming rate.

Outside the door, the assassin's laughter rang out: "Mr. Zhang, you are really willing to spend money, such a large laboratory, you are all airtight with 1 layer of crystalline titanium alloy plates, admire and admire, but your luck today is not very good, I just have something at hand to restrain your alloy plate, haha." ”

Ling Xiao's mind was already completely confused, and she looked at Zhang Yuan helplessly, waiting for his countermeasures.

Zhang Yuan comforted: "Don't worry, we still have a universal field to protect." ”

As soon as he finished speaking, the voice of the assassin sounded outside the door again: "Mr. Zhang, do you think again, without the crystalline titanium alloy plate, you still have a layer of defensive force field, right?" Hehe, I'll tell you, that thing doesn't have one, because I still have a force field interferometer on hand, hehe. ”

As soon as she heard this, Ling Xiao's face became even whiter, her body trembled involuntarily, and she almost couldn't stand.

Zhang Yuan also raised his eyebrows, force field interferometer, this guy has a lot of good things in his hand, the manufacturing principle of force field interferometer is not complicated, in the Golden Field, this thing almost appears with the universal power field, but the principle of this thing is simple, but the manufacturing difficulty is outrageously high, because it requires very, very high processing accuracy, beyond the ability of most of the 3D printers in the Golden Field.

At present, the production pass rate of all known processing methods in Golden Sky is less than 5%, and the cost of a force field interferometer is more than 8 million star coins!

An assassin, not to mention the black technology of a crystalline converter at hand, there are even 8 million force field interferometers, it seems that the employer behind this guy is out of blood.

Just as he was thinking about countermeasures, the surveillance video in front of him suddenly moved, and a vague shadow flashed quickly in the entrance of the building in front of him.

Zhang Yuan stared at it, and suddenly felt happy in his heart: "It's just right." ”

This figure is none other than Levi!
