In Alchemy Of Souls Ep 20, Mudeok stabbed Jang Wook but he was returned to life. The plans for the marriage of Park Dang-goo and Jin Cho-yeon were going on.
Park Jin took Kim Do-joo to show her a house so that she can give her opinion about the house Park Jin wanted to gift Park Dangu and Chojeon on their wedding. Kimdoju also shared her story about how she wanted to live with her husband in a cozy and small house. Park Jin still misunderstanding that she was talking about Master Lee told her that he would gift her a house in their wedding which upset Kimdoju and she instantly confessed that she liked Park Jin. Since Park Jin was slow to understood her feelings for her Kimdujo became upset and left the place.
After returning home and crying, Kim Do-joo discovered that Jang-wook too had a partner who he has chosen to be married to. Kim Do-joo specifically mentioned Heo Yun-ok but was denied by Jang-wook, who remarked, “Don’t be too shocked and listen.” Kimdoju understood that Jang Wook liked Mudeok and wanted to marry her. At the moment, Moo-deok-i was with Joo-wol (Park So-jin).
Joo-wol was overjoyed to see Moo-duk openly admit hee feelings for Jang-wook to and exclaimed, “When Mudeok first came, she was solely full of poison, but now she look lively.” Moo-duk responded, “Did I not tell you? I had changed my fate. I won’t disappear and I’ll continue to exist by protecting those I loved.” Mooduk’s joyful grin made Joo-wol chuckle and she said, “I really like you, please live a happy married life with Jang Wook.”
Park Jin blamed himself for not realizing Kimdoju’s heart sooner, but Jang Wook’s assistance allowed him to locate Kim Do Joo once more. Kim Do-ju was given the balsam seeds by Park Jin as he knelt in front of her and said, “If you plant it now, it will flower in three to four months.” Would you stay with me, he asked. I will, Kim Do-joo declared. Holding his hand, she said, “I’ll match your pace.
In the meantime, Jin-mu failed in his attempt to make Crown Prince Gowon feel inferior to Jang-wook. Jinmu attempted to free all of the soul shifters in the city after remembering that Choi had put a curse on all of the soul unions he had arranged while she was alive, but all of a sudden he saw that Mooduk was a soul shifter.
On the day of Park Dangu and Cho yeon’s wedding had gone to greet Jin-woo Tak, who was recovering. Jin-moo used Mudeok to manipulate and kill Jin Woo-tak, who knew his past and secret organization. He did this by using his own energy to draw out the power of the falling water that was concealed inside Moo-deok-i. Even with the strength of two people, Park Dangu and Jin Cho-yeon were unable to stop her once she regained the power.
At this point, Jinmu entered Jeongjingak and announced that Naksu, the assassin they had been seeking, had appeared. At that time, Moo-deok-i was targeting Park Dang-gu and Jin Cho-yeon as well. When Moo-deok-i was finally being pursued by a Park Jin, Park Jin turned his bow at Mu-deok-i. This arrow was deflected by Jang Wook. Moo-duk-i immediately stabbed Jang-wook, but Jang-wook was further wounded by her sword and hugged her all the way through.
At the end of Alchemy Of Souls Ep 20, as soon as Jangwook called Moodukyi, Mudeok consciousness restored. Did I do it, Moo-deok-i cried out? However, Jin-mu’s bells started to ring again right soon. As a result of Moo-duk’s continued manipulation by Jin-moo, Jang-wook was left behind and died. Jin-moo used this as an opportunity to place blame on the Nak-su and Jang-wook, who was aware of this and closed his eyes.
However, as soon as Jang-wook’s corpse started to burn, he was awakened by raging flames and came out of his death bed futher adding the anticipation for the upcoming ‘Alchemy of Souls Part 2’.
