"Congratulations to welcome the new master to the underworld. He will be majestic in the Nine Abyss and rule the underworld forever!"
The ghost mountains shouted long live, surrounding the new ghost king Dongfang Huan as he ascended the supreme throne of the underworld.
Dongfang Huan turned around, confusion written all over her beautiful face——
Help, she is a postgraduate student who took the postgraduate entrance examination in World War II. Yesterday she was having trouble with calculus, but today she is shocked. Mathematics can really scare people to death!
The worse is yet to come. Dongfang Huan was sacrificed as soon as he reached the throne. He was thrown into the Nether Sea without any resistance and was sacrificed to the legendary extremely cruel and terrifying ancestor of the underworld.
The Green Lotus Industry Fire was burning faintly, and the ancestor sat lazily in it. He looked exactly like the academic dean whom she admired before she traveled through time.
Dongfang Huan asked him carefully: "What is the expression equation of the lemniscate polar coordinates?"
The ancestor frowned, stared at her for a while, and used magic to conjure up a series of equations: r2=a2cos2θ
Dongfang Huan cried with joy, and rushed forward to grab the man's clothes: "Senior! Why have you become such a ghost..."
One thing I have to say is that this look is quite handsome. Take another look, ah is even more handsome. As expected of the school idol, he was so handsome even in death. It would be even more cool if you could teach me how to do the questions...
Ancestor:...
What is she thinking about?
As the Ghost King, I wonder if he, the ancestor, can read minds?
