Xia Fei dove into his experiments on the structure and technology of the nether bell in the lab. Harris, too, had cast his work aside to help Xia Fei with his experiments after he was taught a lesson. There might be flaws with his character, yet his academic skills were unmatchable. Xia Fei was familiar with ancient technology, while Harris had a solid foundation of the theoretical aspect of things; thus, the two were able to complement each other.
It was not simple to conduct experiments on the communication devices of an alien civilization. A week had gone within the blink of an eye. Xia Fei and Harris had yet to set a foot outside the lab since they entered. Apart from eating and emptying their bladders, they did not spend any time for entertainment or rest.
