Destroying the great wall of China is (un)surprisingly not a wall level feat. The wall has a mass of 50 million tonnes = 5 × 10^10 kg.
It is made of various stones including brick and marble. The density of most stones are about 2200kg/m^3 to 2800kg/m^3 so I assume the average to be about 2500kg/m^3.
Volume of stone in wall = (5 × 10^10)/(2500) = 2 × 10^7 m^3 = 2 × 10^13 cm^3
Fragmentation of stone requires 8 Joules per cm^3
8 × (2 × 10^13) = 1.6 × 10^14 J (town level, 7-C)
