The last struggling wounded dragon was cleared by Da Fei, but the system notification of battle's end hadn't appeared, meaning the Dragon Mother still needed to be defeated. Da Fei could already imagine how formidable this Dragon Mother guarding such a vast mine must be, at least no weaker than the Earth Dragon in Divine Punishment Hell, or the Demigod Turtle. And seeing that the other side offered him two chances to surrender, it indicated that diplomacy might solve the issue.
However, before that, Da Fei needed to make the best use of his time to clean the battlefield, search for crystals, transport bodies, and allow Silena's blessing to restore the damage to the warship at the last moment. As for the remaining sulfur in those secret little stone caves within the Dragon Cave, there's likely no time to pick them up, nor did Da Fei intend to. After all, surrounded by enemies, Da Fei could distinguish between watermelons and sesame seeds.
