The God of Cooking Has the Phoenix Seal on His Palm, and the Tip of His Tongue Determines the Palace.

The heroine relies on her cooking skills to "crush" all the way - conquering the servants with delicious food, capturing the princess and queen mother, slapping the envoys in the face, solving the poisonous scheme, and counterattacking from a useless person in the cold palace to becoming a queen. The entire process has an online IQ, the villain is tortured at a fast pace, and the emperor transforms from a "government machine" into a "exclusive wife-protecting madman".
