Summary by polarbearadise (edited by Amaryllideae):
Gong: Chu Feiying = hero of Jianghu
Shou: Jun Shuying = leader of evil sect for awhile then lost the throne to his friend
Two of them, one is righteous, one is evil. One is white and one is black.
It all started from a death match.
Chu Feiyang’s first trip to Cang Lang mountain was the time first he saw Jun Shuying. The name was just a simple name to him, it was just a target he was going to kill on this trip and was just an insignificant brush stroke on his list of people that harmed Jianghu and needed to be removed. After their first battle, Jun Shuying escaped and regained a bit of his strength, but then another enemy came knocking. His life was saved, but Jun Shuying was being fed an unknown pill (that make him able to get pregnant) by his friend, and then his body became painful and cold.
His loyal subordinate then took him to a cave that the previous evil sect leader used to play around with women. Inside there is a hot spring that helps him feel less pain and control the coldness.
Chu Feiyang then sends another letter saying he’ll come back that night to finish the match, but Jun Shuying’s loyal subordinate received that letter instead of him and came up with a plan. Jun Shuying’s loyal subordinate didn’t know any martial arts, but he is an expert in poison. His plan was to poison Chu Feiyang with this poison that triggers his sexual desire, making him lose his mind and only have the will to be intimate with someone. Jun Shuying’s loyal subordinate was successful and was also able to inflict a little damage on him. However, Chu Feiyang’s internal force was even stronger than he thought. Chu Feiyang escaped and as luck would have it, hid in the cave that Jun Shuying was at. One thing led to another, and Chu Feiyang couldn’t control himself because he was in extreme heat, while Jun Shuying was feeling extremely cold and was attracted to heat, Jun Shuying, with barely any layers on his body, seduced (without even being aware of it) Chu Feiyang and kept grabbing on to him, the man couldn’t take it anymore and the lust completely took over his mind.
Jun Shuyin then becomes pregnant, the baby inside of him was absorbing his power to protect itself. He couldn’t get rid of the baby because all of his power would be lost along with it. In his weakened state, his friend returned and fought with him, and he also found out Jun Shuying was pregnant. Jun Shuying didn’t have enough power to win and was once again being fed with a pill, a poisonous one at that. His friend then asked him who the baby’s father was and without any choice, Jun Shuying had to tell him. His friend then wanted him to steal a pearl in exchange for the antidote. The one who guarded the pearl and the treasures was no other than Chu Feiyang, and his friend knew that. During his attempt to steal the pearl, he met Chu Feiyang again and was saved by him. When Jun Shuying woke up, he was surprised when seeing Chu Feiyang. At that time, Chu Feiying also knew that Jun Shuying was carrying his baby and from there on he starts taking care of him.
TL Notes: Another MPreg story :> It sounds pretty terrible and angsty in the beginning but I heard it gets better and fluffier as it goes on.
I had a lot of trouble translating the title so I just left it in pinyin, but it’s interesting because 3 of the characters used in the title are from the MC and ML’s names. (Still not sure what it means but it’s cool lol)
Chu Feiying: 楚飞扬
Jun Shuying: 君书影
If anyone has a good translation for the title do tell me~
