Completing All Trials

Jian and Song Yu have completed their third trial and recovered before going to the fourth trial. They were exhausted and needed some to recover their Qi. They didn't have much time, so they had rushed in the last attempt.

In a half-hour, they completely recovered and then started to move towards the next cave. They didn't know how many trials they had to go through to get to the next part of the tomb. 

So they are not in a rush about clearing the trials. They were working very carefully. They would take every practice very seriously because if they failed one shot, then they would have to go back to the first cave and retake the tests. 

It has been two days since they started to take trials. They have completed all problems in one go, and we're now heading towards the last shot, which would allow them to go to the next part of the tomb after clearing it.
