User blog:Flamesword300/the sword of worlds conquest- inuyasha tetsusaiga and the sounga

if tetsusaiga and tenseiga became one again would it have the ability of saving 100 dead people and if inuyasha used the sword to absorb soungas powers some how, because the two of them weakened sounga the closer they were togther, and to sounga could inuyasha control soungas powers like dragon twister without being possesed?
