The raw materials were all readily available in the warehouse, and the power source came with a variable adapter, which could be powered by a generator or plugged into a standard fusion cell interface.
Just like the black box Chu Guang obtained from the office of the manager of Shelter No. 117, the black boxes here were also self-powered, with remaining battery capacities of 98% and 99% respectively.
Helium-3 belonged to a stable isotope with a very long half-life; under normal usage conditions, one could almost neglect the wear from natural decay. Basically, as long as the battery itself wasn't damaged through mishandling or other reasons, energy storage would last much longer than conventional chemical batteries.
Chu Guang instructed Guo Niu through VM to bring all the necessary materials to him, and also called Dr. Yin Fang, the chief prospector and archaeological team leader from Shelter No. 404.
As soon as he entered, Yin Fang's eyes almost popped out.
