"Papa, how much did we invest in this battle?"
Matthew stroked her head, landed on the castle wall, placed her on his shoulder, and walked towards the castle under the respectful gaze of the soldiers, smiling as he guided her:
"You simply tally it up and see if you can calculate all our investments."
Happy Yaya nodded eagerly, her bright eyes shifting slightly as she carefully started adding up:
"Just these 6,000 trolls will cost us 300,000 gold coins, such a large sum!"
"1,442 adventurers participated in the ambush mission, totaling a cost of 5,768 gold coins..."
