It was just that he had always been lacking this special attribute material, so he had not been able to upgrade the land until now.
Qin Lin studied it again and tried out all kinds of things he had obtained during this time, but he kept getting the same hint:
[ able to upgrade a piece of land with special attributes. Currently lacking special attribute materials, unable to upgrade! ]
Qin Lin studied it for a long time, but he still couldn't find anything. He could only control his game character to go to the lake mine and continue mining.
He had already dug up the 32nd floor of the lake mine.
After entering the 32nd floor, he continued to dig.
It seemed that his luck today wasn't good. He dug three layers in a row without any gains, so he gave up. Otherwise, he wouldn't have found anything even if he dug all the remaining layers.
the next day.
