Shinsoo manipulation is not a requirement to be in the tower the only requirement outside of passing the Floor of Tests is to have a high shinsoo resistance. Rak wouldn't necessarily be the weakest on 40F if he didn't have any shinsoo manipulation as Quant (the weakest Ranker we know of) was able to fight Andorthy who had an Ignition Weapon and Baam's assistance with Fast Skip to a standstill with only physical strength, and while Rak is no Ranker that alone is enough to prove that you can still be a rather dangerous fighter with pure physical strength. Kun said in this very chapter that he uses the baang he can create for strengthening himself so your assumption is wrong.

If I am to be completely honest it doesn't make sense to me that Rak can become this formidable without physical enhancement this fast, but with this chapter I don't see how it can be possible that he can still manipulate shinsoo seeing as it has been proven that baangs are necessary for physical enhancement and that Rak has shown himself incapable of making a baang.
