"He... here... yours?"Rainza asked.
"Yes," said Cleo. "This way.."Cleo said while sticking his fingerprints.
A machine was scanning Cleo's heartbeat, as well as the girl's eyes, in order to open the room in front of her.
Some of Cleo's wind-powered transportation devices are seen in the middle of the wind.
Cleo activates the vehicle, manual activation using the heart rate and eye data scanner, Cleo's fingerprint, making it difficult for others to get inside.
Cleo's laboratory is equipped with his own system, making it different from others. When entering the wrong password, or not himself who goes inside, let alone trying to break into, then those who are there will die.
Incorrectly entering the password, will make the one there explode, destroy the Lab itself and will cause an earthquake, on the seabed due to the collapse of the place.
Of course, only Cleo knows that.
