Ye Xiu, a first generation pro player. Zhang Jiale, a second generation pro player.
There was only a year between them, so there was no need for any courtesies for seniority. Though Ye Xiu would sometimes act the wise, knowing elder, Zhang Jiale clearly had no care for it.
The two's first real top level face off was in the third season of the Glory Pro League.
That season, Team Hundred Blossoms' Sun Zheping and Zhang Jiale, their Blood and Blossoms had fully matured, sweeping across the Alliance and taking first place in the regular season. However, in the end, in the finals, they were met with Excellent Era. The story of how Ever-Stay cut through their combo with his Evil Annihilation had become a legend in this scene.
In the end, Blood and Blossoms fell into the background.
Zhang Jiale wouldn't accept that, of course, so they returned anew in the fourth season.
