It could be a new and powerful enemy that the past Hokages once sealed away. With Naruto's revival of the Hokages, this enemy somehow gets released or starts to break free from its prison. This antagonist would be extremely powerful, having been a threat that required the combined efforts of the Hokages to deal with in the past.
Well, one possible plot development could be that Naruto revives the Hokages to seek their wisdom in a new and dangerous threat that the village is facing. Maybe it's a threat that requires the combined knowledge and skills of all the past Hokages.
Si Teng's resurrection was a plan devised by Bai Ying. Bai Ying designed five steps to resurrect herself. The first step was to get someone to bring Si Teng's corpse there and keep it safe. Bai Ying had been persuaded many times by Si Teng because of Shao Yan Kuan, and in the end, he killed Si Teng when she was unprepared. Bai Ying felt bad after killing Si Teng because Si Teng had only advised her to stay away from Shao Yan Kuan many times, but Bai Ying insisted on being with him. Later, Bai Ying met Jia San. She asked Jia San to bring Si Teng's body there and look after her properly, not letting anyone profane her. Bai Ying did not think of using Si Teng's corpse to resurrect him, but out of a little compassion. But this compassion saved her. If Bai Ying had killed Si Teng at that time and had not buried her properly, or if Jia San had not brought her to Da, she might not have been resurrected. Therefore, Bai Ying had successfully resurrected himself by devising a plan to resurrect Si Teng.
