Fortunately, star charts are quite common, considering that every day many Torch Ship Captains are traveling between the surrounding Floating Lands. The star charts are basically updated in real-time.
However, this only applies to the surrounding hundred light-years or so. If one wants to acquire a broader range of star charts, additional money needs to be spent.
From a hot post on the Torch network, Song Chi downloaded the most upvoted real-time star chart.
This star chart covered an area of about 80 light-years and was said to have been updated recently, with a very high accuracy rate.
Inside the Cang Qiong, having exited the Torch network, Song Chi studied the projected star chart in front of him while quickly planning his next move in his mind.
