Summary of Solo Leveling Manga Chapter 131
Su-ho pours everything he has left into completing the dimensional anchor and making it stable enough to function as a genuine retrieval mechanism. The Itarim, understanding what he is building, send a massive force to destroy the project before it can be completed. Su-ho, Beru, and the shadow army hold the line through an extended battle that tests every resource available. The chapter is a sustained siege sequence — enemy forces attacking from multiple angles while Su-ho keeps fighting and the researchers behind him keep working.
