Gao Yang and Rebrov went outside, listening to the sound of artillery.
"How far?"
Rebrov listened intently, gestured with his hand for Gao Yang to keep quiet, and after a moment of tension, said nervously, "The shells are landing very close to us, no more than three kilometers. This is the sound of a 122mm shell."
After listening again for a moment, Rebrov suddenly said, "152! This is the 152 artillery!"
Gao Yang dared not speak, afraid of disturbing Rebrov. Suddenly, a dense explosion sounded like one unbroken roar. As the sound passed, Rebrov immediately said, "122mm rocket barrage! Otherwise it wouldn't reach this density."
