Status of the 3x Extension of "Empress Cheonha"

Even after extending the 50-episode series to 150 episodes (3x length),
it took until past episode 120 for Gyeong-bin to receive the poison death sentence,
King Jungjong passed away at episode 146,
and it wasn't until episode 148 that King Injong was poisoned, Myeongjong ascended the throne,
and the era of Queen Munjeong and Jeong Nan-jeong truly began.
Episode 150 just rushed through
the 20-plus years of Jeong Nan-jeong's peak and downfall in just an hour and a half lol
