Kapitel 1448: The Black Giant Bird

"Ring…"

The telephone on the table rang.

Roland spent a few seconds rummaging through a pile of machines before finding the connecting receiver, lowering his body and answering it.

The label on the phone indicated that the caller was from the Aerial Knight Academy.

Following the increase of lines to the office, Roland was compelled to add another table to his work area just to hold the phones.

"Really? I'll be right there."

After hanging up, Roland stood up with a joyful expression. He picked up the coat hanging on his chair and draped it over himself.

"Was that Tilly?" Nightingale asked, frowning.

"Yes, the preparations for the big plane is complete, they are going to have its trial flight soon."
