Jack warmly invited the four robots to sit on their seats, and then put heating cushions on their bodies one by one.
"Welcome to join us. I happen to need your help!" It was the first time that Jack had been so polite to intelligent lives. He had shown all his sincerity.
"Hello, master. My code name is Thinking!"
"Hello, master. My code name is Experiment!"
"Hello, master. My code name is Research!"
"Hello, master. My code name is Calculation!"
The four robots introduced their names to Jack respectively and then began to carefully look around the refuge.
"Master, I think we need to work now!" As their leader,
without waiting for Jack's reply, Thinking led Experiment, Research and Calculation carried out data detection everywhere.
