The black dog seemed to be very careful as it licked the biscuit, as if afraid of hurting Lin Ping in the slightest. The old man looked particularly amazed, while Xiang'er couldn't believe it. Even she wouldn't easily put her hand near the dog's mouth to feed it, fearing it might suddenly become aggressive and bite her.
The old man didn't understand, but Liu Chen and the others did. Everything in the world is perceptive, and dogs are even more sensitive than humans. When it sensed Lin Ping's aura, it knew the strength of the person. So when Lin Ping approached, the black dog already knew it was no match for him, which is why it behaved so well.
The old man was not a fool. After thinking for a while, he understood the logic behind it. He kept praising Lin Ping's physique, but seeing Lin Ping's respectful demeanor towards Liu Chen... Could it be that this seemingly frail young man had some extraordinary qualities?
