Constipated!

The carriage driver did what Ban had instructed. He closed the curtain of the carriage before he fed his Monster the sweet potato even with the risk of it containing poison. He gulped a mouthful of saliva nervously as he extended his hands towards his monster. 

When his monster saw the sweet potato on his hands, it was confused at first. But knowing that it was its owner that handed it the food, then it no longer cared as it ate the sweet potato in one mouthful. 

The carriage driver was surprised about it as he did not think that his Monster would eat the sweet potato. After all, he did not try feeding it once and he always just fed it some meat that came from normal animals.
