Description

<!> 此群组已经废弃,如果你是绯红余波玩家,请你自便。在两个账号都受到Email警告后,以及绯红余波组内部一些利己者和背叛者对我的恶意揣测和骚扰,我已经停止管理绯红余波事务,该群也不再供给他们使用。 yDev Community Founded April 26th, 2024 Quality & Speed ------ Founder : qpsxq_Night , tongblood_999A ------ Projects : Crimson Aftermath ------

79 measurements spanning 68 days, net +160. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 2,331–2,564 and does not start at zero.
