They had all been tricked. Now that the grave mistake had been made, it was too late for anything, including the request before their journey to open the coffin and release the Ancestor, sacrificing their own lives to save the world. It was all a lie; the Great Mages had calculated from the beginning that they would not act in such a way.
To be precise, no matter what they did, they could not escape death; opening the coffin early merely allowed them to die with more dignity. In a sense, the other party wasn't entirely wrong.
It indeed was a certain-death situation, without any chance of survival.
By now, it was time to give up. Nalan Shuo also knew there was no hope left; death was merely a matter of how and when.
But not this time, because he was not alone; he came with Yang Xiao. He dragged Yang Xiao into this, and although he could accept his own death, Yang Xiao should not have been involved. It was his fault.
