User blog comment:LastationLover5000/Chapter 411 - In Which What The Hell Did I Read (Quid Pro Quo)/@comment-3030647-20141202001256

Guys, if anyone read the translation comments on the Mangastream version, you would find this: "What I have translated as "Igneel's secret teachings!" is, in Japanese, イグニール直伝 (イグニールじきでん, Igneel jikiden). This translates literally as "Igneel's direct transmission of secret techniques," but that sounds stupid so I changed it. At any rate, what Mashima (or I guess Natsu) wants to convey here is that this technique is something that, presumably, Igneel passed directly down to Natsu."

My assumption is, from that random Dragon Force, that Igneel directly gave him a huge quantity of power after he got out of his body or whatever. Which is why that's possible. Hence the reason for "Direct Transmission" in the translation.

Besides that, I'm not even angry at the chapter. I'm just...it was so boring.
