章 325: Chapter 324 Our Happy Surrender_1

Chapter 324

Ding, congratulations on completing ten Mountain Fortress defenses…

Ding, reward of five Battle Flags.

Ding, reward of fourth-level Mountain Fortress construction blueprint.

...

After so many days, Cheng Dalei himself had lost count of how many waves of attacks he had successfully blocked, but he was clearly assisted by the system. Cheng Dalei returned to his office and shut the door to tally this round of system rewards.

He decided to set aside the fourth-level Mountain Fortress construction blueprint for now, as he wasn't ready to upgrade yet. The most crucial part was the five Battle Flags rewarded by the system.

Blinking his eyes, Cheng Dalei saw the five Battle Flags lying on his desk. He unrolled one, expecting to see a frog emblem motif stitched onto it.

Cheng Dalei made a helpless face. He had expected it, so it was no surprise. What really caught Cheng Dalei's eye was that each of these five Battle Flags was imbued with a special ability.
