After a few days, the new composite material was refined several times, and the design was finally fixed and mass production began. This material is named 'Yulei'.

The drone was destroyed, mainly because the lightning material used was too little and too thin. But even then, it took more than a dozen mines to be penetrated.

The improved new material will be produced in a standard module of one cubic meter, a thickness that, according to the calculations of the test body, should be able to support through storm clouds.

With the possibility of leaving this hellish place, Chu Jungui immediately put the production of imperial thunder to the point where it was second only to the defense system.

The floating base was pulled out of the hangar and was specially optimized by several starship design experts so that the surface of the hull could be covered with lightning bricks without compromising other performance.

But after evaluation, the experts agreed that the original design was too bad to be improved, and the only way out was to tear it down and rebuild it.

Chu Jungui actually didn't care so much about the criticism of his design, he originally just wanted a weapon platform that could fly with kinetic energy, so that he could use the anti-gravity engine he had just researched.

These specialists can be recruited by the Lancers and Pirate Banners, and they all have real skills. With Cambrian's support alone, a completely new design was produced in one night.

The new ship looks much more beautiful, with beautiful lines, like a silver shuttle. The Attitude Control Engine and the Main Engine are usually hidden inside the ship's hull and will only be activated when in use. It's not just for aesthetics, it's about preventing the engine from breaking when passing through storm clouds. According to their scheme, the ship will only rely on anti-gravity engines to propel itself through storm clouds to protect itself to the greatest extent.

Chu Jungui and Lin Xi are quite satisfied with the new plan, the only regret is that the carrying capacity of the spacecraft is average, at most it can only carry a few hundred people, and then consider that they must bring some thunder bricks for backup, and the carrying capacity is even smaller.

After coming to Planet 4 for so long, this is the first time that I have hope of escaping the sea of suffering. The construction of the new spaceship was immediately put on the agenda, and Lin Xi spent a whole day optimizing the entire construction process. Fortunately, two advanced transport ships and a large number of ship parts have been captured at the two bases of the Pirate Flag, which are ready to use, so the construction of the new ship will be very fast, and it will be ready for launch in about a month.

Time flies, and the new spacecraft on the take-off and landing field gradually takes shape, and each day changes differently.

During this time, the beast tide also came a few times, but the damage to the fortress was very limited, except for sending materials. Now the defense of the fortress mainly relies on the weapon station, and the one-** refueling offensive of the beast tide is perfect for the test subject.

As for ground combat, Xiao Kai is now able to control two couriers at the same time, and the strength of the chaotic beast tide has dropped by more than half, and it is no longer possible to pose a threat to the fortress.

In this way, the scheduled day arrived, and the new ship had completed the final commissioning and was ready to set sail.

Before the new spacecraft set sail, Chu Jungui held the last meeting before departure.

In the end, there were 110 approved crew on the spacecraft, except for Chu Jungui Lin Xi and Rose, all of whom were experienced scientists or fighters with outstanding combat power. The rest remained on Planet Four to continue their development.

Now all fighters are able to skillfully control about 10 weapon stations, and with Xiao Kai, it is not a problem to deal with the beast tide below level 5A. In addition, dozens of the most elite fighters have been able to operate 3 sniper weapon stations at the same time to intercept ** missiles. These were originally unnecessary skills, but under the pressure of survival, there are still many people who have developed potential that they didn't even know they had.

In addition to the warriors, the Shadow of Doom Fortress also has a well-equipped team of scientists with expertise in various fields. Theoretically, they could develop a whole system of technology in the fortress.

Unexpectedly, Le Mans decided that Planet 4 was a treasure place for him to make decisive progress in his scientific research, and refused to follow Chu Jungui back to space, insisting on staying. Chu Jungui is not reluctant, and in addition to Le Mans, Xiao Kai does not accept any other scientists. If you want to continue the study of Xiao Kai, you can only let Le Mans stay.

The plan was successfully approved, and apart from the surrender of the captives, leaving Planet 4 was actually very dangerous. The outer space orbit is completely the power of the Federation, and I don't know if Sheng Tang has come.

The plan was set, and after the final inspection of the spaceship, Chu Jungui boarded the spaceship and prepared for another adventure.

The space inside the spacecraft is very small, and the crowd is comparable to that of the World War II submarine of the home planet. This is also the need to minimize the hull and reduce the area affected by mines.

Fortunately, the cockpit was quite comfortable, and he took care of Chu Jungui and Lin Xi to some extent.

Chu Jungui entered the cockpit, connected the warframe to the spaceship port, and took over all control. Lin Xi and Rose took over control of the second sequence as a backup.

As the main energy source is activated, the cockpit is lit up with dim lights, and virtual portholes appear on the bulkhead ahead, reflecting the situation outside the cabin. It's just that the technical level is limited, and it can't be displayed holographically, but can only be presented in the form of ancient screens.

Chu Jungui took a deep breath and started the anti-gravity engine.

With a small buzzing sound, the ship's hull shook, shook a few times, and slowly lifted into the air. Several attitude engines were then activated around the hull, allowing the spacecraft to enter a stable lift-off state.

Chu Jungui raised his head, and the storm clouds in the virtual porthole above his head gradually approached. Through the thick clouds, you can see the flickering thunder inside. As soon as you enter the clouds, there will be countless thunderstorms. It is in this way that the terrifying energy of the Blue Sun is intercepted, so as not to destroy life on the planet's surface.

The storm clouds are getting closer and closer, and without the need for instruments, Chu Jungui can know the exact distance with just his eyes. As he entered within 100 meters of the storm clouds, Chu Jungui reached out and turned off the detector.

The visual view of the virtual porthole disappears, replaced by a large number of numbers and graphs, with a schematic diagram of the spacecraft in the center, showing the current attitude and various flight data.

The ship's hull shook slightly, the main engine shut down, the attitude control engine shut down, and the moving hatch closed, covering the engine vent.

The ship slowed down significantly, but still slowly flew into the storm clouds with the propulsion of the anti-gravity engine.

Chu Jungui suddenly had a creepy feeling.

The ship began to vibrate violently, and the cabin gradually glowed with an eerie glow. Everyone's hairs stood on end, and their heartbeats involuntarily accelerated.

Everyone knew that at this moment, the spacecraft was being bombarded by countless ion thunders, and the instant heat was far higher than that of the stars. As soon as a piece of armor falls off the surface of a violently shaking ship, a large amount of plasma will pour into the ship, completely vaporizing everyone.

At this moment, the ship was as slow as a snail, and it seemed to take 10,000 years to fly out of the storm clouds, and the vibrations of the hull were getting stronger and stronger.

A scream suddenly sounded inside the spaceship,

A female soldier looked at a glowing flame floating in front of her, and she couldn't control herself.
