Roland and other former Federation generals have already delineated the possible scope of a new Federation base based on the data from the previous attack. It is a vast area with a radius of nearly 100 kilometers.

If you change to another planet, it won't take much time to detect such an range, but on Planet 4 you can't use remote control means, so it becomes very troublesome.

The most effective method is also the stupid method that Chu Jungui and Lin Xi once used, that is, the team reconnoiters by car. There are many mature solutions for reconnaissance vehicles, and there is no need to modify them, at most they need to replace the lower main body materials and add some protection. These are the strengths of the Pirate Flag engineers, and Chu Jungui did not waste the computing power of the chip, and directly assigned the task to the engineers.

It took a day for the reconnaissance vehicle to be completed, and in this free time, Chu Jungui re-compared the two design schemes of the engineering vehicle.

I have to admit that the engineers' designs are well-developed and mature, and even the redundant designs that scientists often have are rare. These people are all very pragmatic because they often follow the Legion and have had many experience landing on planetary surfaces. As for the aesthetics of the industrial design, it is also outstanding. If you want to talk about the disadvantage, it is probably that you are not familiar with the physical properties of the materials made based on the local resources of Planet 4.

The test subject and the chip do not have any preconceived notions, everything is based on the highest premise of achieving the mission goal, and will not be constrained by any mature design, which is why there is such an anti-human design as a double-layer manned cube. The advantage of this design is that it can do impossible tasks, or it can be done in a very efficient way. However, there is also a problem, that is, the fault tolerance is not high enough.

Moreover, Chu Jungui further realized that if there were too many similar anti-human designs, then there was no need to wait for the Beast Tide or the Federation, and the people under him would have to rebel first.

In addition, it seems that there are some problems with the aesthetics of the art components, and there is a considerable deviation from the public perception. But the artistic component insists that this is beauty, and even shutting down does not threaten it.

Through the comparison of design, Chu Jungui felt that it seemed a bit of a waste to treat these more than 100 scientists and engineers as pure coolies and warriors, and many projects that have mature designs in human society can be handed over to them to do, and the things made seem to have no other shortcomings except for being expensive, slow, and inefficient.

Chu Jungui felt that he was sitting on dozens of refining furnaces, and he was wealthy, so he could no longer care about so many kilograms of steel. Of course, other materials still matter.

A day later, three brand-new armed reconnaissance vehicles appeared at the base. All three vehicles were all-wheel drive, with two twin rapid-fire guns mounted on each. In addition to ammunition supply, the space in the car is the battery. Each vehicle was loaded with a full 2,000 rounds of shells and had a range of 1,000 kilometers.

Each reconnaissance vehicle can carry six people, so that the three vehicles are almost a formed detachment.

Chu Jungui was very satisfied with the reconnaissance vehicle, and immediately selected 15 elite soldiers plus two scientists, and prepared to set off. However, before traveling, Chu Jungui suddenly felt a burst of inexplicable discomfort. This is unusual for a subject, especially the inexplicable palpitations.

If it is an ordinary person, it will either ignore it or be suspicious. But the subject was not an ordinary person after all, and he initiated a self-test and quickly found the source of the problem. It turned out that the metaphysical component was secretly playing tricks: it didn't know where it got its permissions, secretly disturbing the subject's heartbeat, lowering his body temperature, and sweating a little.

Then Chu Jungui had symptoms such as palpitations, chills all over the body, and cold sweats.

After being discovered, the metaphysical component gave only four words: the trip is dangerous. As for where the danger comes from and how it knows it, the metaphysical component is not to be mentioned, and it has a great demeanor.

Chu Jungui also knew the virtues of metaphysics, and he didn't bother to ask. However, it does seem that three reconnaissance vehicles are not enough to go deep into the wilderness. After thinking about it for a while, Chu Jun changed the plan to 12 cars. One of the cars carried a pulp power furnace for emergencies, and the other had a mobile manufacturing machine. With such a small detachment, Chu Jungui believes that its strength has surpassed that of the reinforced company of the special forces.

The reinforced company of the special forces is often close to 200 people, and Chu Jungui is less than 100, and the difference is filled by the test subjects themselves.

After another day's delay, the convoy finally set off to reconnoiter the Federation's new camp.

According to the plan, the reconnaissance unit will approach the target area at a speed of 40 kilometers per hour, and then speed up to 70 kilometers to conduct a large-scale mobile reconnaissance, and it is expected that it will take four hours to complete the target area, and then return at full speed regardless of whether there is a result or not. The entire operation will last one day. With such a short window of time, it is unlikely that the beast tide will be caught. The reconnaissance vehicle can reach a maximum speed of 100 kilometers in the cross-country of the all-earth type, and the main combat vehicles of the Federation cannot catch up.

In the early morning, 12 reconnaissance vehicles lined up and left the fortress. In addition to scouting the predetermined area, geomorphological mapping and exploration along the way are also important.

The convoy's path was winding and winding, avoiding the forest as much as possible, and passing through as quickly as possible. The first few hours were fine, and we arrived at the target area without incident.

At this moment, a gently undulating slope appeared in front of me, scattered with patches of double-leaved wood. Visibility is about 10 km, and there are no traces of federal activity in the field of view.

The reconnaissance convoy began to pick up speed and move forward in an S shape in order to expand the search area. The experienced Roland sat in the front car, his eyes vigilant, constantly scanning the surroundings.

After a while, he suddenly shouted, "There is an anomaly in front of the left!"

The convoy then turned around and drove to a small hill. Chu Jungui looked at the hills. There was nothing unusual on the surface of the hill, just small purple grass covered with blades of grass that were constantly swaying. But there are some subtle color differences in the grass that you can't tell if you don't look closely.

Roland turned the reconnaissance telescope into spectral contrast mode and noticed the difference.

The color difference is caused by the difference in growth time, and the mature purple leaf grass is darker in color, and the new ones are more showy and bright. In fact, there were traces left by the pressure of the tracks on the hill, but now it was all covered with purple leaves. If you come later, even the color difference will disappear. Planet 4's ability to clean itself up is much stronger than that of its parent planet.

Roland jumped out of the car, carefully dug up a piece of soil in the trace area, observed the cross-sectional distribution for a while, and said with certainty: "This is the trace left by the Federation planetary chariot, yes." It was from this area that they should have set out to attack our fortresses. ”

"And what about their base?" asked Chu Jungui.

At this moment, there is a vast area around, and there is no shadow of the federal base.
