"Missiles again?" After the previous few things, Su Yun was resistant to this thing from the bottom of his heart, although he knew that there was indeed a missile silo in this underground base, but he still selectively ignored it, and he didn't even go to check the sad place.

"Otherwise, what do you think is better?" The virtual girl glanced at Su Yun and asked seriously with a curious look,

"I can't say it either, it's just that kind of softer feeling" Su Yun danced with his hands, with an ugly face of Party A's request to change the design needs, but the virtual girl didn't show any disgust, but tilted her head and cheeks lightly and began to think about this problem,

"What about a drone?" The virtual girl suddenly blessed her heart, raised her head to look at Su Yun, and said,

"Drones? Do we have the technology for this? As soon as Su Yun heard the words of the virtual girl, he immediately felt that this was more reliable, and quickly asked if it was difficult to realize this thing.

"No, but this thing doesn't need any technology, as long as it can fly, I have the technology of aerodynamics and the like, and it's no problem to roll out a simple prototype in reverse, and it doesn't need any electronic operating procedures just to send out the probe, if you remove the return to home system and make it a one-time use, let it fly in a straight line in one direction, and then calculate the time to throw the probe, until the energy runs out of it should be able to explore a very considerable range." The virtual girl clicked on the screen a few times, and let Su Yun take a look at the estimated detection range,

Because there is a vein resource point where this kind of thing is completely depends on God's face, and since it is a vein, it is impossible to go straight up and down only one point, it must be a scattered and irregular extension of the distribution, so there is no need to be too serious when looking for it, only need to cast a net generally, and then find it and then follow the vine to touch the melon, so it seems that the virtual girl's method is efficient and high, and the operation is not troublesome, it is definitely the best way at the moment,

The two of them summed up the details a little, and they didn't delay much, and immediately began to implement it, first of all, the virtual girl handed over the blueprint of the probe to Su Yun, and asked him to take it to mass production, and then he began to design the drone, after all, it was a one-time, no extra system settings were needed, and even electronic components were not needed, as long as it could be controlled to deliver the probe at a specific time, and the technical content of the entire drone was not even as good as a complex toy, So before Su Yun came back, the virtual girl completely got this thing done,

On the other hand, Su Yun took the blueprint for the production of the probe and went directly to the temporary production site by the ruins of the novice base, first, he didn't have enough materials on him, although the probe was not a single material, but according to the girl, the demand was huge, so the best way was to produce it in situ and bring it back, and second, the novice base was completely independent of the system of the underground base because of traffic problems, and it was not connected to each other, so Su Yun had to come and run anyway,

The blueprints and materials are complete, and you can start production directly, and because this thing is not large, and the technology level requirements are not high, it can be produced in large quantities with the existing 3D printing equipment, and this thing may be used in the future, Su Yun directly produced forty groups according to each group of twenty-five, a full thousand, and it took nearly three hours for five 3D printers to get these things,

【Explorer Measurement Probe Type I】

[The Explorer Measurement Probe is inexpensive, robust, and requires very little skill, but the conduction stage speed is very slow, and it takes about ten hours to collect reliable survey data]

【Required Skills】

Geological Exploration II.

Electronic Information Processing I.

Surveying I.

Structure value: 1

[volume] 0.01 cubic meters

Other: Detector weapon category

[Technology Level] 1

[Detection radius] 2 km

Su Yun took one and weighed it in his hand, this kind of probe is not only small in size, but also very light in weight, the weight of a single one is only 200g, which is suitable for playing with drones, as for the messy pre-skills that are needed, Su Yun himself does not have it, but the operation of this thing is handed over to the virtual girl, so it can be directly circumvented, and it can be regarded as picking up a system loophole,

However, the detection range of this thing is a little less because of the relationship between volume and cost, but it can't stand the large base of Su Yun's hand, and the effective detection range after the whole thousand are scattered is about 12,000 square kilometers, and the data obtained in the end after removing some accidental losses is definitely enough.

After this was done, Su Yun went to the control center again, and then brought back the drone manufacturing blueprint that the virtual girl had just done, the volume and shape of this thing are similar to the Global Hawk generation UAV developed by the United States, but the power source is directly supplied by energy crystals, so the endurance and load capacity have been greatly improved.

And because the design idea of this thing is disposable, abandoning most of the electronic equipment, it can only fly in a straight line, so it is outrageously cheap, since there is not much waste, Su Yun also produced ten units in line with the principle of maximizing efficiency, so that they can spread the probe in ten directions in the place that they have explored before, which can not only greatly improve efficiency, but also effectively avoid the trouble caused by repeated detection,

However, because the scope of exploration is too huge, far beyond the signal distance that the current virtual girl can control, so Su Yun has to get some sensors that enhance the signal propagation distance, and after the location designated by the virtual girl is put into place, it is loaded according to the standard of one hundred probes per drone, and the startup program of these drones has been handed over to the Q version of the girl, as long as Su Yun wants to start it at any time now,

After calculating the direction a little, Su Yun always felt that it was not very reliable in his heart, and it seemed too simple, but simple things did not necessarily mean that they were not good, cheap and reliable things such as AK47 were still easy to use even in this era, although it could not be said that everything was simple and rude, but there seemed to be nothing wrong at the moment, and if there was really any problem, it would just be a waste of materials, and it would not cause any irreparable losses, so Su Yun did not hesitate, Directly loaded the energy crystals, activated the drones, and launched them one by one,

All that remains is to wait for the result, Su Yun looked at the last drone that had become a small black dot farther and farther away, and turned around and walked in the direction of the underground base.
