Patrick's father and son shop had plenty of skilled technicians with considerable experience in crafting emeralds; in Bogota's Emerald Street, it was regarded as a leading professional storefront.
Emeralds are brittle, and crafting them requires great care; otherwise, they may become damaged. Furthermore, because Gao Yang and his team needed to work on many pieces of jewelry all at once, and all of them involved top-quality stones, the utmost caution was needed. Therefore, it would take them four days before they could collect their finished jewelry and accompanying authentication certificates.
As the only non-combatant in the Satan Mercenary Corps, Little Donnie stayed in the hotel in Bogota. Once Gao Yang and the others returned, the first thing that happened was Ivan transferring the six million, five hundred thousand US dollars due to Gao Yang and his team into Little Donnie's account.
