Special-shaped heat storage brick and heat storage body formed by laying heat storage bricks

The invention discloses a heat storage brick and a heat storage body formed by laying the heat storage bricks. The heat storage brick comprises a zero brick, first bricks and second bricks. The zero brick comprises a square brick body, wherein the top face of the brick body is divided into n * n square grids, n is an even number and is not equal to zero, bosses are arranged on the grids on the odd lines of the odd rows and on the even lines of the even rows. Two parallel supporting edges are arranged on the bottom face of the brick body, each supporting edge is provided with a protruding circular truncated cone and a concave circular truncated cone hole, the circular truncated cones on the two supporting edges are located on the same diagonal line of the brick body, the circular truncated cone holes in the two supporting edges are located on the other diagonal line of the brick body, and the distance between the circle center of each circular truncated cone and the circle center of the corresponding circular
