The task of the three bodies. Liu Tsysin

In those days when China was experiencing the consequences of a brutal “cultural revolution”, during a secret military project, signals were sent to space to establish contact with an alien mind. One of the signals was accepted by a civilization located on the edge of death, and now the aliens are preparing to invade the ground. Upon learning of this, people were divided into those who are ready to give our vicious world under the management of the highest mind, and those who until the last will fight against this invasion.
