Blake saw how the fight between Robus and the horde of Bison went. And although he had his own guesses about how Robus would fare against a horde, it was still quite surprising for him to see Robus was really pushed back despite the two sides' massive difference in strength.
After the dozens of bison remaining made their way past Robus, leaving about ten bison carcasses with their souls floating above their bodies, Blake flew down close enough.
"Are you okay, Robus?"
"R, rr."
"It's normal for you to have difficulties fighting against a large number of enemies with only your fist, don't think too much about it."
Despite understanding what Blake meant, Robus still couldn't accept that he, someone that could easily kill one of the bison with a single punch, would be overwhelmed by those creatures due to their numbers.
