While the Alliance was still forming, Wei Chen was asked to set up a team, which became known as Blue Rain. At some point in the early times of the league, Blue Rain held a training camp, where the future prospects of Blue Rain, Yu Wenzhou, and Huang Shaotian, took part as well as Fang Rui. With Huang Shaotian being seen as the future ace-player of Blue Rain, the club began carefully raising his Blade Master account. This period of time became known as "The Beginnings of the Legends of the Sword Saint." After losing to Yu Wenzhou multiple times during a practice match, Wei Chen, the Captain at that time, made the decision to step down.
Fang Shijing became the user of Swoksaar and Captain during Season 3 which allowed Yu Wenzhou and Huang Shaotian an extra season of practice. Blue Rain failed to enter the playoffs that season. Fang Shijing retired at the end of Season 3 and Yu Wenzhou was promoted to the captain of Blue Rain.
During Season 6 of the Alliance, Blue Rain beat Tiny Herb in the finals, stopping Tiny Herb from becoming the 2nd team to win back-to-back championships and becoming Champions themselves.
In Season 8, Blue Rain clinches the 1st place in Regular Season and enters the playoffs finals for the second time after defeating 301 Degrees and Misty Rain. They face Samsara in the finals but lose in an unprecedented fashion, causing the Alliance to change the rules for the playoffs.
Prior to the start of Season 9, one of their All-Star players, Yu Feng, transfers to Hundred Blossoms but they promote one of their youth prospects, Lu Hanwen, from the training camp. Lu Hanwen becomes the youngest player to make his debut in the Glory Professional Alliance and receives the Best Newcomer award for his performance that season. In Season 9, they finished fifth in the Regular Season and are knocked out in the Quarterfinals by Tiny Herb.
Before the start of Season 10, their Thief player Lin Feng transfers to Wind Howl. Blue Rain finishes third in Regular Season and faced Happy in the Quarterfinals where they lost. In the Quarterfinals match, they became the first team to lose a match whilst winning the Team Competition.
