[Beauty with a delicate body and soft body VS the prince of war god who is cold outside and hot inside]

In the eyes of the world, Shen Mingjiao, the side concubine of Prince Su’s mansion, is extremely beautiful. King Naihesu is obsessed with Crown Princess Su Qing. Shen Mingjiao has been in the mansion for ten years, King Su has never stayed in her courtyard once, and even recorded the illegitimate child outside under her name, and finally died in the palace change, what a pitiful person!

…

Shen Mingjiao: “…” How can she be pitiful?

Is it because the garden of the palace is not big enough, or the days of shopping are not enjoyable enough, or the cheap son is not cute enough!

If King Su wants to guard his body for Bai Yueguang, let him guard it. Such a marriage does not need to sacrifice both spirit and body. King Su is definitely a good husband who is 24 filial!

After being reborn, Shen Mingjiao originally wanted to go through the plot with peace of mind, but… after blowing on the newly dyed Kou Dan, it seemed a bit insincere to watch King Su miss Bai Yueguang!

Feng Lisheng married Shen Mingjiao only out of sympathy. At first, it was just that the palace had added more chopsticks. Later, seeing that the palace had become more alive under her care, the rough guys under him were finally able to eat well. Hot meal.

In this way, year after year, he gradually got used to having such a person in the palace, he always thought that Shen Mingjiao was like the bright lights of the palace in the dark, no matter how long he was away, she was always there.

Until that day, he rushed all the way from the border into the palace, saw her lying silently in a pool of blood, at that moment, his eyes turned red and he went crazy.

…
