I think this is a re-upload of the [GM-Team][国漫][观海策 第1季][Guan Hai CeⅠ][Strategies of Sea ObservationⅠ][2018][01-16][HEVC][GB][1080P]. I can't be sure but either way but it no longer has any seeds available. So I thought I would go ahead and share it since I've renamed the files a long time ago. If their torrent finds new life again, I'll probably end up removing this one. Episodes are all 1080P https://myanimelist.net/anime/38689/Guan_Hai_Ce
