忠 義 堂 ， 少 玉 被 奉 上 堂 主 之 位 ， 洪 嘯 天 要 三 陽 講 出 當 年 一 件 往 事 ， 聽 得 少 玉 血 脈 忿 張 。 龍 五 面 對 少 玉 及 兩 老 開 始 解 釋 ， 少 玉 震 驚 。 龍 五 由 三 十 萬 兩 講 到 錯 殺 好 人 ， 願 意 傾 盡 家 財 賠 償 ， 最 後 龍 五 對 著 關 帝 神 壇 拔 刀 自 插 三 刀 ， 血 流 如 注 。 天 地 會 的 弟 兄 們 都 聳 然 動 容 ， 少 玉 內 心 悲 戚 ， 表 面 卻 無 動 於 衷 ， 令 紅 梅 ?龍 五 不 值 ， 憤 然 扶 走 龍 五 。 洪 嘯 天 因 心 願 已 了 ， 在 狂 笑 之 中 暴 斃 。 天 地 會 驟 遭 大 變 ， 眾 人 都 均 感 惶 惑 。 龍 五 本 是 少 玉 的 偶 像 ， 誰 知 竟 成 天 地 會 的 叛 徒 ， 令 少 玉 大 受 打 擊 。 少 玉 的 大 義 滅 親 並 不 被 天 地 會 的 人 認 同 ， 更 受 到 眾 人 的 冷 遇 ， 心 裏 不 快 。 少 玉 見 到 聶 冰 ， 聶 冰 解 說 天 地 會 的 人 冷 淡 的 原 由 。 少 玉 哀 歎 忠 孝 難 以 兩 全 ， 卻 又 被 師 傅 聶 三 陽 叫 到 河 邊 訓 斥 一 頓 。 少 玉 抱 定 錯 不 在 自 己 的 宗 旨 ， 不 論 誰 勸 ， 都 不 願 回 家 。 龍 五 在 得 知 ， 既 痛 又 恨 又 悔 ， 決 定 徹 底 毀 掉 龍 家 ， 為 天 地 會 贖 罪 。
