While traversing the dimensional wall, there are three main areas of damage on the Shuttle, namely the warp engine, the antimatter thruster, and the antimatter energy stack. And to fix these three things, it will take about 10,000 stardust points.

In other words, Jiang Feng has already completed one thousandth of the target.

Looking at the pitiful golden light particles in the inventory, Jiang Feng couldn't help but shake his head and sigh.

"This stardust printer is really a money-burning thing."

Ten thousand points of stardust may sound like a lot, but once his plantation is on a scale, sooner or later, piles of gold will flow from the continents of Aditya and Noren to his hands. Compared to silver, which has only 0.2 per ton of stardust, gold with a content of 1 is undoubtedly more cost-effective to convert into stardust points.

This 9.1 stardust point, Jiang Feng plans to use it directly, in exchange for some high-tech products that the workbench can't make, especially things used for self-defense. After all, he only has a Galaxy K1 on his body now, which is more than enough to deal with ordinary people, but if he encounters a powerful wizard, he will be a little stretched.

As for the object of printing, Jiang Feng already had a plan.

In the drawings stored in the brain database, there is an attack drone called "Ghost A4", which is shaped like a fist-sized metal ball, which can be stuffed into your pocket when not in use, and after activation, it can be suspended under the drive of the magnetic levitation engine, and at the same time, a laser emitter shaped like an eye is unfolded at the front end, which can emit a laser beam of 10mm caliber, which just makes up for Jiang Feng's lack of output in terms of energy attack.

Its energy source is mainly electricity, which can be supplemented by solar energy or direct transmission and other means, which can be said to be a very practical individual support weapon. In the Federation's weapon classification, it is listed as an E-level sequence, mainly used for land combat purposes below level I civilizations, and is printed with stardust points, which only requires 6 stardust energy.

It is worth mentioning here that when fighting against different levels of civilization, there are many different levels of weapons used on the battlefield according to the different demands of war. On the one hand, this is due to cost considerations, after all, the military spending of the Federation fleet is not unlimited, and on the other hand, it is to protect its own technology and prevent technology leakage.

Nuclear fusion batteries and antimatter batteries can be used as power sources for different types of power armor, and even if a power armor with a nuclear fusion battery as the power source is scrapped, the loss is only a little military spending, and if the power armor with antimatter batteries as the power source is scrapped, the loss is not only money, but also may make its own technology stolen by the inferior civilization through reverse engineering.

Even if the latter, who is armed to the nerve endings by technology, has a much higher survivability on the battlefield than the former, there is still no equipment with a 100% survival rate. Just as millions of swarms can overwhelm the Federation's Marines, a sufficient number of missiles and conventional weapons can equally pose a threat to the Federation's weapons. Just like tickling, scratching too much will also shed a layer of skin.

Especially for civilizations that have entered the early days of the space age.

This concern is not unfounded, because many of the Earth Federation's own technologies were analyzed from the opposing civilization during the war. Even if many low-level civilizations with weapons cannot be restored by reverse engineering, they may be sold to the opponents of the Earth Federation in the form of exchange for benefits, which will eventually lead to the leakage of weapon data and related technologies.

The Federal Operations Command even has a dedicated risk assessor who will evaluate the details of these wars beyond the war itself, from equipment attrition rates to technology attrition statistics, with an error of less than 5%.

These data will be used as a reference to determine the types of troops and equipment involved in the war, and even down to the exact user of the equipment, so as to ensure that the outcome of the war is balanced by risk and the benefits to the Federation are maximized.

Of course, there is not much to say about the targets on the purification list, and usually nothing is left after a Star Destroyer cannon. Because there is no need to enter into a land war, and there is no need to worry about post-war negotiations, and most importantly, to satisfy the political needs of the various factions within the Federation. The appeal is simply to erase the target from the galaxy's territory.

The purification behavior here is usually aimed at civilizations whose genetic characteristics are far from those of humans, or the first-level peak and second-level idealistic civilizations that are no longer able to correct their development concepts and put them on the "right path".

The pale yellow particles of light converge in the silver-white disc, and layers of transparent ripples slowly spread out in the air, just like an unfolded origami, the shape of the silver metal ball is outlined by the transparent light particles, and the complex structure that originally required tens of thousands of production lines to complete the processing was completed in an instant under the interference of the origin of the universe.

After all the light dissipated, a silver-white metal ball fell on the silver platter with a bang.

And at the price, the pale yellow light particles stored in the transparent energy tank were much weaker.

Reaching out to pick up the silver-white ball, Jiang Feng gave an order through his brain in his heart.

"Smart brain, the control terminal connected to it."

[Connected...... Please enter a personalized name]

After thinking for a moment, Jiang Feng really couldn't think of any personality name, so he said casually.

"Let's call it Spectre No. 1."

[Set, Ghost No. 1, for you]

The electronic eye shrank slightly, and a silver metal ball rose from Jiang Feng's palm.

Connected to the drone's control program through the wisdom brain, Jiang Feng controlled it to rotate around his fingertips, and then pointed to the steel plate in the corner of the laboratory.

The crimson laser beam exploded instantly, and the moment it touched the steel plate, the steel plate was like ice cream poked by a soldering iron, instantly melting through a large hole as thick as a thumb, and leaving a red-hot fracture in the direction of the ray.

"It's good."

"High-heat laser beam, the damage type should be equal to the fire type of witchcraft in witchcraft, and the damage level should be at least above the first level of witchcraft."

"It's a pity that I haven't met a serious wizard yet."

"I'm looking forward to the effect of this thing on the Guardian of Idealistic Civilization."

After holding it in his hand like this for a while, Jiang Feng briefly reviewed the control instructions of this kind of spherical drone, and then reached out to pick it back from the air, causing it to enter sleep mode.

In the Federal Army, it is said that the elite "hell paratroopers" in the orbital airborne forces, each paratrooper's brain has been specifically strengthened by divergent thinking. Paratroopers who have undergone this enhancement will be able to attack in different directions at the same time while advancing towards the mission objective.

As for Jiang Feng, he is studying a command major, and the strengthening direction of the intelligent brain is mainly focused on the two parts of intelligent device connection and intelligence analysis, and it is already his limit to be distracted to manipulate a ghost.

"There's 3.1 stardust energy left, what can I do with it?"

Looking at the remaining pale yellow light particles in the energy tank of the Stardust Printer, Jiang Feng fell into deep thought.

Since it was decided to use these stardust to strengthen the strength of self-protection first, there was no need to save on this bit of stardust. It's just that what the next stardust spots are used for has become another question worth thinking about.

Why don't you get a few more magazines for the Galaxy K1?

Or just a more powerful rifle?

At this moment, Jiang Feng's gaze suddenly fell on the soul fragment of Solol next to him, and the thought in his heart moved, and another thought popped up in his head.

"Zhi Brain, are there any drawings in the database about the specific enhancement of Zhi Brain?"
