Taking one last look at the seemingly bottomless, calm lake, Xu Xin was worried that the giant cavern under the lake might continue to expand, but there was nothing he could do. He sighed and carried Keke back.
Back at the mine's location, his pet had been digging for a long time. The pit was already filled with coal, yet it continued to dig incessantly.
"Alright, that's enough for now!" Xu Xin hurriedly stopped his pet.
The pet let out a dissatisfied sound. It seemed to have a penchant for mining, treating it as a hobby to expend its energy.
In that one hour, his pet had significantly expanded the mining pit. The ground was covered in coal; each piece definitely amounted to thousands.
The efficiency was simply extraordinary!
Xu Xin spent quite some effort to collect all the coal from the ground into his backpack, totaling 26,534 pieces!
Over twenty thousand pieces!
