In the US section of the US-Mexico border, H Town.
In a secluded warehouse on the outskirts.
This place used to be rented by a border trade company, but it had shut down due to poor management; recently, the warehouse owner received a new lease contract.
The new tenant was very generous, paying a year's rent upfront without haggling.
But there was a condition: they claimed they were renting the warehouse to develop a new technology project and, for patent secrecy reasons, hoped the landlord would not come around for no reason, leaving a phone number and saying to contact their secretary with any issues, urging not to disturb them as they were very busy.
The landlord looked at the business card; it bore the name of a distinctly Chinese company "Falcon Technology Development Co. Ltd."
Looking at the tenant, who appeared to be younger than thirty, youthful, a Chinese-American.
