Summary of Solo Leveling Manga Chapter 125
In the aftermath of the third Apostle’s defeat, Su-ho finds a dimensional thread — a faint connection through the space where the Apostle came from — that his father’s memories tell him is connected to where Jin-woo is fighting. He cannot follow it safely yet. He is not strong enough. But he can use it to send a signal — a pulse of Shadow Monarch energy that travels along the thread toward his father. He does not know if it arrives. He sends it anyway and returns to the work of defending Earth.
