Bai Yi knew nothing about what was happening on Luo Fan. Although the antenna monitoring array on the new Mars could receive almost 100% of the electromagnetic waves emitted by Luo Fan into space, this information would be filtered out as noise by the filter on the detection station before entering the central host.

As a border guard AI deployed here by the Galactic Alliance, Bai Yi does not need to care about the actions of the Luofan people under his nose. He only needs to listen to the reports of several high-level organizations on specific channels, and monitor the general direction of the entire civilization to prevent them from self-destruction during the period before the arrival of the immigration fleet.

Therefore, Bai Yi still maintains a completely laissez-faire attitude towards the Luo Fan people. Simply put, if you want to commit suicide, stay away from here and don't die in my hands.

Although the Luofan people belong to the same type of Homo sapiens as the humans on Earth, that is, they have almost the same DNA sequence as the humans on Earth, and there is almost no obvious difference in appearance.

But they were still aliens after all. In front of the entire Galactic Alliance and even the United Nations on Earth, Luo Fan seemed insignificant. Bai Yi's current protection of them was simply because it was in the best interests of the Alliance.

It is necessary to ensure the diversity of civilizations within the Milky Way so that the Galactic Alliance, which is composed of various ethnic groups, can remain vibrant and prevent it from sliding into the abyss of decay and degeneration.

Of course, besides protecting Luo Fan, Bai Yi now had more important things to do. New Mars had already completed the metallization of all its plains. A large number of construction machinery was working on the surface, moving mountains. The soil pushed down from the mountains would be sorted, and the barren parts would be filled into rift valleys and basins, leveling the surface overall and facilitating the subsequent metallization project.

The remaining valuable parts will be sent to the ion furnace, where they will be processed into materials and then piled up at the launch site. Several large transport planes are already ready to transport the alloy to the space construction areas at the two poles of the planet.

Two universal space construction platforms were anchored at the north and south poles of the new Mars, with the building framework continuously expanding outward from them. Fiber-like tubular structures composed of nanomaterials possessed exceptional strength, connecting the outer structure to the main platform and preventing it from falling toward the planet under the influence of gravity.

Space builders busied themselves working on these extended structures. Some of the more advanced ones could already be seen as the bases of massive cannons. Each of these focused tachyon cannons had a caliber of 1500mm, with 128 positioned at each of the North and South Poles, for a total of 256 tachyon cannons. These would be disconnected from the construction platforms during construction and anchored near the poles of the new Mars using their own space anchors.

These powerful tachyon cannons form the primary component of the fortress planet's long-range firepower and are the Galactic Alliance's most crucial superluminal long-range firepower. While these cannons, due to the inherent properties of tachyons, are not as powerful as conventional beam weapons of the same power, they can achieve instantaneous hits on a battlefield measured in light-minutes, a significant advantage unmatched by any other weapon.

Below the artillery array is the air defense position. A large number of laser and live ammunition artillery batteries form layers of air defense network. Such positions are ubiquitous on the new metalized Mars. They are responsible for shooting down small enemy aircraft approaching the planet or intercepting missiles.

Then there are the 4000mm railguns on the equator. Because they require frequent reloading, railguns must be mounted on planetary surfaces rather than anchored in space like energy turrets. The railguns fire projectiles weighing thirty-five tons, traveling at 99% the speed of light. While the immense vibrations created by firing have always limited the railgun's accuracy at long range, and 99% light speed isn't considered fast in space, as medium-range weapons, railgun shells pack a terrifying amount of kinetic energy, a lethal threat to armored targets. At the right angle, a single shot from the New Mars railgun could pierce a conventional cruiser, piercing it from bow to stern.

Then there are the planetary missile arrays and carrier-based aircraft hangars. The missile arrays are mainly divided into jump missiles, cruise missiles and torpedoes according to the engine type.

The so-called warp missiles, in a sense, have gone beyond the category of missiles and can be called disposable drones. This type of missile is equipped with a subspace engine, and their bodies are specially designed to fly at tens of thousands of times the speed of light in the subspace.

If the enemy is not protected by a subspace shield, the warp missile can even jump directly into the interior of the enemy target.

However, this internal attack method is extremely difficult to execute, especially against massive or dense objects. As the only force capable of widespread influence across twelve dimensions, gravity also disrupts the subspace. While this disruption typically doesn't cause prolonged loss of direction, it can be enough to degrade weapon accuracy, causing missiles intended to launch from within an object to emerge from inexplicable locations.

In addition to various missiles, the fortress planet also possessed a massive hangar, which housed a vast array of drones and other equipment. However, all of these weapons pale in comparison to the planet's massive cannon.

The Destruction Ray is a planet-mounted cannon mounted on the planet's central axis. A massive rift on New Mars, 1,500 kilometers wide and 4,000 kilometers deep, is reserved for the planetary cannon and its associated equipment. Powered directly by the planetary reactor, each firing is devastating. Even a colossus designed to shatter planets would be crushed by it.

The planetary fortress spacecraft is the epitome of the giant ship and cannon concept, and its super exaggerated main gun also has very serious limitations when used.

The main gun's rate of fire was very slow, requiring several hours to fire. Furthermore, because the bulk of the gun's structure was buried deep within the planet, the planetary cannon's arc of fire was limited to plus or minus three degrees. The planet itself had to be rotated before firing to align the muzzle with the target, making the destructive ray a significant hindrance against highly maneuverable targets.

In fact, the Galactic Alliance is already discussing whether to eliminate the planetary cannon from the design of its next generation of planetary fortress ships, replacing it with more versatile sub-caliber artillery, but no one can guarantee the consequences of such an approach. The Space Force, which evolved from the Navy and inherited the Navy's tradition, is a branch of the military that places a heavy emphasis on experience. Such a radical design that eliminates the cannon would be difficult to accept until it achieves a significant advantage.
