Just before the palace is due to be completed, Caesar intervenes by sending legions to try to arrest the Gauls, after he realises the three Gauls are in Egypt when a spy disguises himself as a worker, and sees the effects of the magic potion. The Gauls fight off the Roman soldiers, but the commanding officer proceeds to shell the building with his catapults. In desperation, Asterix and Dogmatix deliver the news to Cleopatra. A furious Cleopatra then hurries to the construction site to berate Caesar. Caesar's legions are ordered to fix the damage they caused (without any magic potion to help them) and the palace is successfully completed on time. Cleopatra wins her bet and covers Edifis with gold. Edifis and Artifis reconcile and agree to build pyramids together, and Cleopatra gives Getafix some papyrus manuscripts from the Library of Alexandria as a gift. The Gauls return, but Vitalstatistix criticises Obelix trying to give an Egyptian style point to menhirs.
