What if the star is over-inflated?

Point technology and administrative management capabilities, dismantle outposts, and greatly improve production capacity.

1 Not hostile to other countries (important premise! )

Diplomatic negotiations, asking the other side to allow civilian ships to move (not to mention military ships ... even a small country will not be 99.9% open to you ...)

After the other party accepts it, use the folk immigrant ship to sail to the target planet.

(If the other party agrees, the scientific ship/engineering ship/immigrant ship can pass through its territory ...)

4 colonial construction of the Thai outpost and then it can be expanded to the _ side! !

After you have a new territory, you can set the star field according to the situation and recover the colonial space before expansion! This way is suitable for our country surrounded by other forces, and it is safer than going to war directly to open the passage.
