Finally some truimph for our Joseon scientists, as Jang Yeong Shil figured out how to include semi-automation in his upgraded version of water clock, and Jang Hee Jae is enlightened (or is he?) that Jang Yeong Shil is naturally gifted. I’m not sure if this week’s episodes signify any big changes in Jang Hee Jae, but certainly he has come to acknowledge that only he can change himself.
King Sejong revealed to Jang Yeong Shil his wish to create a set of words for the people, and his full understanding that whatever plans he has for the benefit of the Joseon people, he will be met with full resistance from the minisiters and Sungkyunkwan. It cannot be demonstrated more fully with the presence of Jo Kwang, an official of King Taejong’s court as well as an influential neo-Confucian scholar. Jo Kwang comes across the sundial Jang Yeong Shil made for the villagers in Namyang, and decides that he must be killed, for it not he’ll bring chaos and unrest to Joseon (cue roll eyes). For those who’d watched before Tree with Deep Roots, you’ll know the bloodshed and opposition that occured alongside with the creation of Hangul was no joke.
Back to Jang Hee Jae, his crazy friend found him at Jang Yeong Shil’s workshop, deliberating over whether to burn the clock or not. Crazy Friend reveals the reason behind his immense hatred for Jang Yeong Shil and blames Jang Hee Jae for it, and being an incurable obstinate fool, Crazy Friend proceeds to burn the clock after fighting Jang Hee Jae. The latter, bless his soul, grabs Crazy Friend’s sword and stabs him to prevent the clock from being burned. Jang Yeong Shil finds Jang Hee Jae and talked sense into him, letting him know that they share the same curiosity and passion for science.
And so, Jang Hee Jae decides to isolate himself to rediscover what science means to him, though he was soon found by Jo Kwang’s bodyguard, who threatens him to provide forged almanac records which Jang Yeong Shil made previously (which Jang Hee Jae saved from being burnt a few episodes ago). King Sejong announced he wish to conduct another solar eclipse ritual based solely on the calculations done by Joseon’s own astronomical calculations, and it was a move which Jo Kwang took as a chance to deliver a blow to Sejong’s plans. Again, Jang Hee Jae is faced with the dilemma of being a traitor or a double spy, which we cannot decipher as he continues to work with Jang Yeong Shil and Lee Chun to complete the semi-automation of the clock.
