"Ah! This part is broken too, gotta fix it quickly, it's so expensive..."
"It's over, it's over, Yaya's gold coins aren't enough to build the next Yaya No.1."
"We need to get Yaya No.1 moving quickly; taking down a legendary Catachang Demon could easily earn us another 10 million gold coins!"
"The burst system still needs adjustments, the power is too high, causing too much wear on the parts."
"The joint areas are under a lot of pressure, seems like I'll need to design a more efficient motion conduction mechanism in the future..."
"The center of gravity also needs adjustment, but fortunately, the material is strong enough, so there haven't been major issues."
"The mana energy conduction structure needs reinforcement; the strength is still somewhat low and can easily hit the limit..."
"The combo strategy is effective, and it can be further optimized to be more compact and more lethal."
"Let me check other inventions, see if they can replace this part..."
"..."
