Hi Sacrar, in my opinion this course is recommended to be taken.
1. The numeric score is not helpful because Zi is also -2. Let's analyze further: Hai is
(a) a moving line
(b) produced by changing line Shen.
On the contrary, Zi is non-moving. And Zi represents other courses being considered.
Conclusion: other courses are lesser in quality
2. This particular Day Clash is a positive one
4. Offspring is actually a Hostile God, so being hidden is not bad at all. The Xu Tomb is irrelevant, because this line is hidden!
Back to #1: Shen producing Hai means the course is prepared with seriousness and structure (Officer), and has gone through post-production verification (changing line).
