Summary of Solo Leveling Manga Chapter 123
Su-ho fights a second Itarim Apostle and defeats it, but the cost is higher than the first. His power is growing quickly but the Itarim are sending stronger entities each time, and the escalation rate is outpacing his development curve. He pushes his levelling harder, clearing the most extreme available dungeons while simultaneously managing Earth’s defence. Beru, watching the young man drive himself toward his limits the same way his father once did, is openly proud in the blunt, unsentimental way that is entirely characteristic of him.
