No matter what kind of defense module, or all kinds of special munitions, or even specially developed models for Planet Four, there are a lot of spare items at the Legion space base in planetary orbit, with the exception of Cambrian.

The Cambrian was designed hundreds of years ago, and can only be found in museums throughout the Federation. Because of its unique structure, which is particularly resistant to the environment of Planet 4, it was rediscovered, and after redesign, several strong protective versions were specially built and distributed to the base on the planet's surface.

The performance of the new version of Cambrian is not as good as the original version, so naturally it will not produce more, and only three units were originally produced, but the other two were distributed to the forward base of the Pirate Flag, one was destroyed by Chu Jungui, and the other became his trophy. At this moment, the entire N7703 galaxy is not able to find any more Cambrian.

It will take at least 3 days for the new Mastermind to be produced and transported to Planet 4. That is, for the next 3 days, the Doomsday Shadow Fortress is truly streaking.

Without Cambrian's computing power, the effectiveness of the fortress's defense system would have been reduced by at least half.

Joseph looked at the time and said, "Fortunately, in another eight hours, a new round of supplies should arrive." ”

"Supplies have already departed, which means that what we are waiting for is only regular supplies. ”

Joseph sighed, "Why are you living so sober, aren't you tired?"

"I'd rather be tired than die. ”

"I went to work. Joseph waved his hand and drove the badly damaged mecha to help the soldiers clean up the corpses of the war beasts and clean up the battlefield.

William shook his head and was walking towards the nearest ruin, when suddenly a series of warnings appeared in front of him!

A behemoth appeared in the distant sky, and it was a floating base that went and returned!

Chu Jungui stood in the floating base, looking at the Doomsday Shadow Fortress in the distance, approaching quickly. In fact, the floating base was not repaired, and during this time, Chu Jungui just changed the direction of the main engine, turning the original base head into the base tail, and letting the relatively intact side rush forward.

The Shadow of Doom Fortress was in turmoil. William's heart sank, and he immediately shot out all the missiles that could be launched, and then ordered someone to replenish the missiles of the launch module as quickly as possible.

Fortunately, the Shadow of Doom Fortress was still out of the strike range of the floating base, so William immediately struck first.

Watching more than a dozen missiles attack, Chu Jungui also showed a touch of relief in his solemnity.

"Looks like you're running out of missiles!" said the subject with a smile to himself, and then manipulated the weapon station to destroy the incoming missiles one by one.

If there is a surplus of ammunition in the Doom Shadow Fortress, then hundreds of missiles should be launched in one go, directly destroying the floating base, and not leaving Chu Jun a chance to return. If the missile launch module is insufficient, then it should also be launched in several waves in a row, not only one wave as it is now, and then there will be no then.

Without missiles, what is the subject afraid of? Everything in this fortress is already in his pocket.

The floating base accelerated forward, slightly arrogant.

Then I heard a few muffled toms, and a piercing scream came suddenly, and several shells flew by the side of the floating base, only a few meters away from hitting.

Startled, the subject swept his gaze, and by comparing and analyzing the images in his memory, he instantly locked on to the source of the attack: the rapid-fire cannon of the Doomsday Shadow Fortress.

Chu Jungui was dumbfounded, forgetting for a moment the range of the rapid-fire cannon of the Doomsday Shadow Fortress. He did not expect that the rapid-fire guns of the fortress had a range of more than 15 kilometers. This is far beyond the range of the weapon station of the floating base, and the shells cannot be intercepted, so Chu Jungui does not dare to use the floating base to resist the fortress city defense artillery.

The test subject was indignant in his heart, a rapid-fire cannon specializing in short-range defense was against a primitive war beast, what was it necessary to engage in such a large range?

However, complaining and complaining, Chu Jungui was not slow to react at all, and immediately raised the height of the fortress, and at the same time, the engine was fully opened, drawing an irregular trajectory in the air, turning around and flying away.

Seeing the floating base leave, William was also stunned for a moment, only to suddenly realize, and he was so remorseful that he wanted to give himself a few slaps. He was also limited by inertial thinking for a while, and he was bent on using missiles to solve the problem. Missiles are indeed the best means to deal with large targets such as floating bases, but the problem is that these missiles are originally intended to deal with war beasts, so they are all area kill types, and the so-called high speed is only relative to other missiles, and the absolute speed is not too fast. Even many intraplanetary vehicles are much faster than it.

William also forgot that there were still a dozen rapid-fire guns. These rapid-fire guns are not very powerful per shot, but each turret is capable of raining hundreds of shells in a minute. It will take no more than three minutes to destroy the subject's floating base.

But it's useless to regret it, Chu Jungui has already flown away in the floating base. Once a subject realizes a mistake, it will never be a waste of time to correct it.

The floating base leaves, but William is in a dilemma.

He looked in the direction of the floating base and frowned. Old General Leitner came to his side and asked, "What are you thinking?"

William said: "I wonder if it's time to evacuate. ”

Leitner neither roared nor mocked, but pondered, looked at the devastated fortress again, and thoughtfully.

"If the people above are determined to abandon this planet, then perhaps a better way is for us to land on the other side of the planet. Even if it's rebuilt, it's better than staying here. ”

The old general said: "Is this necessary? Hasn't he already been beaten away by us? The rapid-fire cannon at the base is a sharp weapon against that kind of big iron box." ”

"If you run away, you can come back. And I'm sure he'll be back much sooner than we thought, and by the time he does, he'll probably have the weapons to suppress our rapid-fire cannons. ”

"How is this possible?"

"Although his aesthetics are a little worse, he can build a floating base and make some new weapons. What's more, it is actually very easy to suppress our rapid-fire turret, as long as the caliber is large enough and the barrel is long enough. William smiled wryly.

At this moment, on the floating base, Chu Jungui has sent the new design drawings to the production area in the base, requiring immediate production. Return to the Shadow of Doom Fortress as soon as production is complete.

Roses appeared on Chu Jungui's monitor, and she asked curiously, "Do you have a way to deal with the rapid-fire cannon of the fortress?"

"Of course! It only takes 8 hours. Chu Jungui didn't hide his secrets, and sent the design drawings over.

When Rose saw it, she suddenly couldn't laugh or cry. The design picture is a mechanical keyboard that is three full circles larger, and the 280mm caliber is particularly dazzling.
