It was only after Su Yayan's death that she realized that she was a malicious cannon fodder female character who became a scapegoat in a Mary Sue story.

Yin Mingyu 007 worked until she was bald, and still could not afford to buy a one hundred square foot apartment in the first tier cities.

After her sudden death, she transmigrated through to the Chengye Dynasty and was a shu daughter of the Yin family in Jiangnan. Once liberated, she just wanted to do nothing but eat and wait to die as a salted fish.

House fight? It has nothing to do with her. Isn’t it nice to lie down?

Compete for favor? It has nothing to do with her. Isn’t it nice to lie down?

Looking for a good future? It has nothing to do with her. Isn’t it nice to lie down?

However, her older di sister who married the Xie family in Jiangnan passed away. Her di mother, because of her young grandson, chose Yin Mingyu after circling around in the courtyard.

Being a new wife was difficult, being a stepmother was even harder.

Yin Mingyu was never afraid of the di mother and spoke directly, “I don’t want to.”

The di mother also directly expressed her opinion: Not willing doesn’t work.

Yin Mingyu: “……then whatever.”

Anyway, she always lies flat. She will marry over in the future. Don’t blame her for just looking after her own happiness and interests.

The protagonist is a guy who is among the stupidest of the stupidest in the school. In this school, your grades can, under the supervision of teachers, take a virtual form to do combat! However, if you leave an examination half way, you get zero marks. A bright and cute girl, Mizuki Himeji, was having a high fever during the examination. Despite her potential to be the second highest scorer in the level, she obtained zero marks for having left due to her illness and is thus allocated to the worst class, class F.

Grades mean almost everything. For Class A, they have a smart-looking teacher, a plasma TV as big as the entire wall as their blackboard, personal laptops, personal air-cons, refrigerators, adjustable seats and all kinds of different appliances. Within the refrigerator, there are all kinds of drinks and snacks. Their ceiling is made of glass, the wall lets them put up high-class drawings and plants.

As for Class F, the worst class… They have Japanese desks and seat paddings. Their blackboard is dirty and there is no chalk even! Someone complains that the legs of his desk are broken, so the teacher asks, “Didn’t we distribute some glue to stick wood together? Glue it back yourself later.” Another one complains that wind is blowing in from the broken window. The teacher says, “I got it. I will apply for plastic bags and invisible glue to fix it later.” There are spider webs everywhere, not a patch of the wall is clean. A unique moldy smell spreads across the entire room; it must be from the old tatamis used to tile the floor. This is the status of class F.

The protagonist feels displeased at such an arrangement, and seeks help from his friends to try to make a change through summoning war!! And they devise all kinds of plans to try to beat the famous class A, intending to get class A’s classroom and equipment if they win!!
