an galactic plane approached the Godhapur pyramid. From the plane it emits an electric signal. This signal was then captured by a device and converted into radio waves so that it could be translated into human language. This modern communication tool can be used as a transmitter and translator.
Finally scientists can establish communication with the crew on inter-galaxy planes.
The crew claimed to be from Planet Xilam in the Andrenam galaxy. They are looking for a key that can open Pandora's boxes on their planet. From their search, they found out that the key was sealed in a place and it turned out that the tracking signal came from the Godhapur pyramid. They intended to ask for the key. But scientists who are also researching the pyramid cannot give permission because this is an area that cannot be damaged.
"If you can't ask, we want to borrow it."
"Where do we know that you will return again?"
After a long period of communication and debate, finally there was an agreement
"We will stay here and send two crew to go home to deliver the jar. Let us be a guarantee."
"All right, then, but before returning home, the two crew that will return will install explosives so that we won't break our promises."

Thank you,@xpilar for the chance and welcome from your holiday
Warm regard from Indonesia
