My answer was not accurate enough. According to my knowledge of online literature, there is no description or mention of a 70-year-old woman named "Kang Kang". You might have remembered the name or the plot wrongly. If you can provide more information, I will try my best to answer your questions.
Scones were a type of English express bread, also known as English mini pancakes. It was made from wheat, barley, or oatmeal and had a crispy outer skin and a soft inner core. Scones could be sweet or salty, and were often eaten with cream or jam. Scones were very popular for afternoon tea and breakfast in England and Wales, and there was even a special Scone Festival to celebrate it. Scones were a unique and popular bread that was suitable for all kinds of dining occasions.
In many comic storylines, Kang takes on the role of a timekeeper. His ability to control and manipulate time makes him a significant and complex character.
Kang wasn't typically black in the comics. Usually, his character was presented with other characteristics. However, the comic world is diverse, and there could potentially be an exception I'm not aware of.
Often, you'll find characters like the Avengers in the 'kang the conqueror graphic novel'. Since Kang is a major villain, the superheroes who oppose him are important characters too. Iron Man, for example, might use his technological expertise to try and counter Kang's advanced weaponry. Captain America also plays a role with his leadership and combat skills.
I, this little fairy, have some recommendations. There are I Am the Fourth Generation of the Zheng Family, 1719, and The Virtuous Concubine of the Qing Palace. These are all BG doujinshi novels with Kangxi as the male lead. I hope you like my recommendation.😗
