Chen Du looked at the large pile of materials and countless equipment in front of him, and his excitement was spontaneous. These materials are hard to buy in the market, and if it weren't for the cooperation with the fat man, he wouldn't dare to think about it.

This time there were more materials than he had seen at Yang's Auction House last time, and they were piled up in three small warehouses. And the equipment sent by the fat man is also very valuable, many of which he has never seen, and all the equipment adds up to hundreds of millions, which can be described as a heavy gift. And the fat man gave this gift, Chen Du couldn't give birth to a trace of refusal, so he could only secretly write down this favor.

Commanded everyone to help place it, and it took a busy afternoon to put all the equipment and materials in place.

Card analyzer, micro-precision liquid quenching device, constant temperature maintenance instrument...... Looking around, Chen Du couldn't help but be satisfied, having a state-of-the-art laboratory had always been his dream. However, I didn't expect this dream to come true so inadvertently. Although these equipment are not the best in the Federation, they are by no means capable of being purchased by ordinary groups.

What could be more wonderful than this?

It was already dark outside, and Chen Du remembered that he had been busy until now and had not eaten. I was about to look for something to eat, when suddenly, the alarm sounded.

"Unknown intruder spotted! Level 1 alert, all units are immediately in place! ”

The radio in the building was constantly broadcasting, and everyone was immediately on alert. Kaxiu, who was on duty, was ready for battle as soon as possible, and those who were resting also quickly entered the combat post.

The empty base immediately appeared even more empty.

Twenty people guarding such a large base is too weak. It is precisely with this in mind that only one access point is now used in the entire building, and all other access points are closed. This also means that they only need to concentrate their combat power on this one channel. The building's protection can be very good, and if you want to enter by destroying the exterior wall, without a special card, you will need to continue to attack for a long time to achieve your goal.

Operational Command.

Bagnel sat casually in the command chair, surrounded by a curtain of light. Each light curtain is about two meters long and two meters wide, and twelve light curtains form exactly one circle. The command chairs can be rotated at will, and the image outside the base can be clearly seen from these light curtains.

On a light curtain in front of him, a black shadow could be seen on the edge of the lawn.

It was the first time Chen Duan had seen such an advanced combat command room, and there were several light curtains in front of everyone, and some of them were constantly working on it.

What makes him feel the most novel is the constantly flowing symbols on some light curtains. Looking closely, he realized that these high-speed moving symbols were a complex string of numbers.

Chen Du did not systematically study mathematics, which is extremely rare among this card maker. But this is not to say that he is completely ignorant of mathematics, on the contrary, he has profound attainments in some areas of mathematics.

This is directly related to the theory of chipping he studied. At the heart of the theory is computation and optimization. When he first learned the theory, he suffered a lot from the difficult and profound content, and in order to learn the theory, he studied mathematics for a long time. It's just that he studied mathematics just to learn the theory of fundraising, so the content of his study is only for the content related to the theory of fundraising.

In other words, he is seriously biased.

There were only three or five people in the huge combat command room, and Bagnell was lazily half lying in his chair, half squinting, not knowing whether he was looking at the light curtain in front of him, or if he was sleepy and wanted to sleep.

Bagnell suddenly noticed Chen Dui entering the operations command room. Hurriedly sat upright: "Why are you here?" ”

"When you hear someone invade, come and see."

"Don't worry, there's only one here, and it's estimated that it's a pathfinder." Bagnell gestured to the light curtain.

Only then did Chen Du notice the black shadow on the light curtain.

Looking at Bagnell's fearless expression, Chen Du suddenly wanted to see him commanding a battle.

"What is he doing?" Seeing that he was slow to make a move, Chen Du couldn't help asking.

"Hey, hey." Bagnell said proudly, "He's worried, probably thinking about how to get closer." ”

Indeed, Bagnell's measures were extremely thorough, which Chen Du admired. Even if it was himself, he didn't know how to get close to the base without being detected. I sighed in my heart, professional is really professional, and I would never have thought of these ideas.

Half an hour later, the dark shadow had not moved, but Bagnal still had a very unconcerned expression, and he was very patient, without the slightest restlessness.

After another ten minutes, the black shadow finally couldn't hold back and began to approach the new base.

I saw him bent on his waist and slowly moved forward. The movements are fast, quite brisk, and with the cover of the night, it is really not easy to spot. He could be spotted from so far away, and the eyesight of the people who found him was amazing.

Glancing disapprenantly, Bagnell bared his teeth and smiled, "This guy is going to be unlucky." ”

Sure enough, before he finished speaking, he saw a sudden burst of light on the black light curtain.

The infiltrator triggers the device that is ambushed in the grass, and Chen Du remembers the day he saw Bagnell placing a device in the grass. That's the density that you can touch almost every two steps.

What kind of grass is this, this is obviously the sea of jamming mechanisms!

Chen Du suddenly felt some sympathy for the infiltrator.

"With the directional blasting mechanism and the high-sensitivity triggering device, hehe, the explosion range is less than one meter. But the power at the center of its explosion is enough to break through the three-star energy shield card. No matter how you listen to Bagnell's introduction, there is a smug smell.

However, the infiltrator also shone brightly, and a pale blue energy shield rose up.

The energy shield shook violently, but it was still holding on.

"Four-star energy shield!" Bagnell's eyes lit up, and he suddenly felt a little energetic.

The infiltrator probably knows that he is exposed, how can someone who can lay this kind of protection be touched and the mechanism has not been discovered? Looking at the lawn that stretched for several kilometers, the thought of the unguardable mechanism in the grass made his scalp tingle, and he asked for his surname to rise into the sky.

When he rose into the air, whether he was advancing or retreating, he did whatever he wanted.

Chen Dui's attention was also attracted by the pale blue energy shield on the light curtain. Three-star energy cover cards are more common, four-star ones are rarer, and five-star ones are even rarer. In fact, the use of energy cover cards is very technical. The same energy shield card, in the hands of an ordinary card repair and a defensive card repair specializing in energy shields, the protective surname is very different.

A combat-type card that has the ability to use a four-star energy cover card, then the card he is good at should have a five-star card!

Those who can use five-star cards are masters of the best of the best, no matter where they are.

"There's a big fish! Hey. Bagnel touched his chin with an interested expression. Then he said to himself: "Don't treat me well, let me feel at ease!" ”

Chen Dui, who was listening to it, was completely speechless.

"Attention all, band attack ready, and a warm welcome to our guests." Bagnell commanded the microphone in front of him.

Seeing that no one was attacking, the infiltrator holding the blue energy shield boldly approached the base.

"It turned out to be a rookie." Bagnell muttered, his face lacking in interest, but the tone of the command immediately followed was extremely cold: "Attack! ”

Before the sound was gone, a beam of light, a wave blade, and an energy shuttle all flew towards the conspicuous infiltrator. Before the infiltrator could come, a series of screams rang out.

There are a total of twelve attacks, divided into four waves, each consisting of three attacks, with two channels separated by 0.2 seconds.

Every wave of attacks, every attack, has been carefully arranged, and every reaction of the opponent is all counted.

In the first wave of attacks, the infiltrators didn't care, and such attacks were not violent. However, he was still quite impressed, and of course he could see that the angles of these three attacks were finely arranged. It was difficult for him to dodge them all, but for Cassius of his level, this level of attack was not enough to make him flinch.

Only one of the three attacks attacked him, an energy shuttle, causing his energy shield to shake violently.

The second wave of attacks after 0.2 seconds shocked him, and the other party really had a back move.

In the flash of light, he suddenly found that the angle of the second wave of attacks and three attacks was really too tricky! With the energy shield propped up, no matter how he dodges, he will be hit by two of them. And if he doesn't hold up the energy shield, although his flight speed can be increased and he is more agile, the possibility of being able to dodge it all is still very small.

There is a good chance that he will be hit by one of these attacks. However, without the protection of the energy shield, a single attack would have been enough to kill him.

In the middle of a second, he subconsciously chose to continue to hold up the energy shield, which in his opinion was safer and safer. The protection of the four-star energy shield is so good that ordinary attacks can't shatter it at all.

In the second wave, two attacks hit his energy shield.

His face changed suddenly!

It was like throwing another stone into a lake that had not yet calmed down, and his energy shield shook even more violently. However, what made his face change suddenly was not this powerful wave blade attack, but another attack in this wave of attacks.
