Decrease dramatic ping (Euw account used in Asia)

I am currently on holidays in China and my friend back in Ireland wants to play lol with me. I played one game of ARAM to test the game out and the ping was a average of 416ms. I heard about these programs like WTFAST and game booster but will these programs work at a very high scale? To decrease my ping down to its normal 30ms Also anyway at all to lower these ping cost free?
