In the game "No Man's Sky", in order to use the portal, you must have the corresponding portal rune. Without the rune, the portal cannot be used. Portal runes can be obtained through main quests or through bugs.
Some tasks in the game can reward portal runes, and you can get all the runes by completing all main tasks. This is the most basic method to obtain runes, but due to the long and scattered main process, obtaining runes is slow.
If you like to explore, you may not have completed the main quest yet and may not have enough portal runes. At this time, you can use the following opportunistic methods to use bugs to brush the portal:
1. First find a portal rune and mark its location.
2. Back to space anomalies.
3. Take a mission in the same star system as the rune, preferably a mission adjacent to the rune.
4. After completing the task, fly directly back to the rune location.
5. Disconnect from the Internet here and collect the runes.
6. After receiving the runes, return to the main menu, disconnect from the network and load files.
7. After reconnecting to the network and loading the file, return to Space Anomaly and receive the same mission again.
8. Repeat the above process to brush the portal runes repeatedly.
But it should be noted that there are risks in exploiting bugs. Once fixed, this method will no longer work. Therefore, it is not recommended to use bugs to brush portal runes.
