Spar and the evolution theory
Lucas told everyone about the shelter requirements and they were fascinated. But at the end of the day, only John and Lucas were the ones who were truly happy.
They were the ones that were taking care of all the commanding and living conditions and after knowing that Lucas could upgrade the shelter again with some effort of his own.
He had started it and made it something very important in his daily routines.
Now that the number of planks was voluminous, they had to make an upgrade in order to be better efficient.
John started making something that was long overdue and after only a few hours in the morning, a makeshift lumber axe was ready with better sharpness than before.
For the task, John had placed two of his leveling points in strength while two more in stamina without taking any advice from Lucas. As expected, he wasn't able to get up from the floor for a whopping ten minutes scaring everyone other than Lucas who only sighed in annoyance.
