In the temporarily established command center, Zhao Tianling sat there with a gloomy expression.
"Commander, all four fronts have been pushed back, and there are fifth-tier zombies in the north front. Shelters No. 6 and 8 are retreating with heavy losses and urgently request support!"
"Fifth-tier zombies?" Zhao Tianling suddenly straightened up.
"When did fifth-tier zombies appear in Yu Lin City? Wasn't it said there weren't even fourth-tier ones half a month ago?"
"Commander, Yu Lin City is strange. We found the number of zombies decreased, but their quality improved. We used to estimate about 300,000 zombies, now it's at most 150,000, but each one is at least second-tier or higher," said the leader of the military reconnaissance team, sounding incredulous.
"In just over half a month, Yu Lin City has changed so drastically?"
Zhao Tianling slowly stood up, staring gravely at the city map on the table.
