The Star Realm Tunnel had a diameter of one light-year and transected the Star Realm Ball, which was over ten thousand light-years thick.
This was in no way comparable to some mountain tunnels on Earth, neither in terms of width and diameter nor length. The technical difficulties involved were incomparable.
It could be said that this was a magnificent and spectacular interstellar project.
When the Wandering Star System seized the chaos to rush into the Star Realm Tunnel, they finally experienced the vastness of the one-light-year-long Star Realm Tunnel.
Constant Star Lu Chen felt like he was an ant entering a tunnel, surrounded by seemingly endless space, which made him profoundly aware of his own insignificance.
Moreover, Green Star and Wandering, both in terms of size and mass, were much less than Constant Star Lu Chen, even being just one in several millions of his size. In the Star Realm Tunnel, they were like specks of dust and not worth mentioning.
