Jian had confronted Song Yu about her identity and the tomb. She had explained everything to Jian, which helped him get more information about the tomb.
He was able to find the workings of the tomb. Now he knew the route to follow. If he had not confronted her, then he would have wasted his time in searching for the clues.
After knowing that the tombs trials will be in three different mountain peaks, he formed the plan according to it. So he and Song Yu have started to move towards the first peak.
Song Yu was still wary of Jian even though he had already told her that he wasn't here for the inheritance. But Jian didn't have any problem with it. He allowed her to walk behind him while creating a route for her to reach the peak.
As the mountain in the tomb was covered in forest and also had herbs and beasts. Jian had kept his open for spices that were not in his sect.
