Confused by Joy and Poisonous Concubine

Hua Xiaolan, the ace of the international special agent team, is codenamed "Flower Demon". After accidentally traveling through time, she woke up as the idiot Ninth Miss Hua Guanyue from the Hua Family in Nancheng, Huangwu Kingdom. She was also drugged, stripped naked, and sent to the bed of a strange man. Facing the stunningly beautiful man in front of her, a certain woman had no soft words at all. She was destined to be the best in the world. Anyway, she had been drugged, so she had to eat it and wipe it clean! Who knows—— The fiancé's family sent someone to inform her that Hua Guanyue had an affair with someone before her marriage and was not a woman, so the engagement was terminated! Another infatuated fifth prince came to propose marriage. I robbed you. Come with me! There is also an imperial edict to give flowers and moons to the dying fourth prince for joy! Hua Xiaolan was angry. Did he think she was the silly Miss Ninth Hua Guanyue? He possesses the power of controlling flowers, and his mother-in-law opens the back door. He can travel across the continent with just one copy of his peerless skills! It didn't matter if she married to celebrate the occasion, she swore that she would kill the dying fourth prince completely! But—— Why did the fourth prince, who was about to die of illness, not die no matter how hard she tried? Fragment 1 "Sister-in-law, this is rose tea that I brewed with my own hands. It can beautify the skin, stimulate the menstrual flow, activate the meridians, harmonize the liver and spleen, regulate qi and the stomach..." A certain woman introduced eloquently, looking at her sick husband-in-law with enthusiasm. The most important thing is that she added ingredients to this tea. It is guaranteed to be colorless and odorless. If you take one sip, you will die, which is a natural death. "Oh." Huang Beichen responded lightly, took the cup and drank it all in one gulp. When he was done, he poured the cup back to indicate that he had finished it. One minute, two minutes, one hour. Looking at Huang Beichen, who was still alive and well, the woman's face turned completely dark. Clip 2 "My lord, the emperor saw that you were still alive after such a long time, and was afraid that I could not serve you alone, so he sent a dozen beauties. There is also Miss Zhang from Zhang Shangshu's family who has been obsessed with you for a long time! You must not be polite, otherwise you will not be sorry for the emperor's hard work!" A certain woman gloated while biting an apple, but she would not say that it was actually her suggestion to the emperor to do this. Hum, if the poison can't kill you, so many women can't kill you if they come together! "Oh." Huang Beichen still responded lightly, as if it had nothing to do with him. The next day, when a certain woman excitedly ran to Huang Beichen's door to check the results, she found that all the dozens of beauties were weak, as if they were about to die... "Huang Beichen, are you... Too fierce?" "My lady is very considerate. The generals in the army have returned triumphantly and really need a reward." A certain female black line. [This is a story about a battle of wits and courage between a female protagonist who pretends to be a pig and eats a tiger, and a male protagonist who appears to be weak but is actually sinister. Who wins and who loses, please see the details. The introduction is weak, but the plot is absolutely awesome!
