He and Li Muchen had previously joined forces to fight the Purple Lightning Dragon-Eel. Although his cultivation realm had advanced significantly since then, the Purple Lightning Dragon-Eel's power certainly could not compare to that of a true flood dragon.
Su Biluo's strength might be slightly superior to his, but not by a wide margin, as evidenced by the sword strike just now. If the two of them combined their swords, even if their power doubled, it would only be equivalent to four Lu Jingšans.
Lu Jingshan knew very well that if it were a flood dragon, let alone four of himself, even ten of himself would never be able to sever a dragon's body with a single sword strike.
