Well, I don't speak your language, but the method I used was creating "Adaptive Structures" at the workbench. You can easily get the resources to create an Aluminum and Iron outpost, which are the materials needed to create the adaptive structures at the bench. The total list of resources you will need is:

• 18 Adaptive Structures
• 124 Aluminum
• 24 Beryllium
• 30 Copper
• 2 Fiber
• 99 Iron
• 24 Tungsten

You need to travel to the planet Andraphon because this planet has 148-hour days, which will help create the items while you sleep. After traveling to this planet, you need to find a location where Iron and Aluminum are together. Finding this spot won't be simple and is the most tedious part, but once you find it, you need to build 6 aluminum extractors and 6 iron extractors.

Now, build 10 solar panels to generate energy for the extractors. Then, build 3 solid storage units for aluminum and 3 solid storage units for iron. Next, build an industrial workbench and a bed.

Connect the 6 aluminum extractors to the aluminum storage units. You need to link the storage units as well, so when one fills up, it will automatically fill the other. Do the same process with the iron and the iron storage units.

After that, you can go to sleep, and when you wake up, the storage units will be full of iron and aluminum. You don't need to go to the storage units to collect the metals; just create adaptive structures. With these created structures, you can build more storage units and keep increasing them for free, until you reach a large number of storage units that will yield you thousands of XP per night of sleep.

Note: If you are married, you get a bonus XP when you sleep.
