The people of the city are stuck in snow mountains due to heavy land sliding. The only way to save them is to rescue them and take them to the nearest city. However, the snow is so deep that even the best rescue teams cannot get to the bottom of it. The only way to save the people is to dig a tunnel to reach them. But the problem is, the snow is so deep that the tunnel cannot be dug without a gigantic machine. 

You are the only one who can save the people. So, get the machine and start digging the tunnel.
