Being in the World of Arknights...Thing's are going to change drastically and...You best be ready for what's to come ahead.

At a low point in his life, Xia Ruofei discovered that a scroll that was passed down in his family had a hidden secret: it contained its own independent world.

In the space, there was a spiritual pond that enhanced the growth of plants. There were mysterious spiritual flowers that could cure illnesses. Time in the independent world flowed at a pace ten times that of the outside world. Everything he planted there was of supreme grade and grew at a rapid pace. Everything he raised gained sentience.

From that day forth, Xia Ruofei began a different, brilliant life of planting succulent plants and vegetables, raising animals and flirting with beauties.

One day, billions of young and middle-aged people around the world were pulled into an underground palace survival game.

If you want to survive, you have to fight with dungeon creatures to get resources.

- Description from novelbuddy

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!!
