The battlefield signifies death. As soldiers, sacrificing for the country with no regrets, every mission requires a mental preparation for sacrifice; a farewell letter is placed on the neatly folded quilt, but if given the chance to live, who would choose to die? As an officer, Luo Zheng naturally hopes to successfully complete the mission, but he even more hopes to bring everyone back intact. Although this mission was very perilous, it was considered mission accomplished, and the subsequent war has nothing to do with him, hence there's no need to stay.
Bar also knew that this wasn't Luo Zheng and his companions' war. Being able to establish a connection with the Government Army, and indirectly putting some pressure on the Government Army, Bar secured unimaginable benefits for himself. Bar was very grateful to Luo Zheng and his team, and with the Guard, rode camels to see them off for a full ten kilometers.
