As it turned out, Xiaoba was still too naive to contend with a bad brother-in-law.
Xiao Hen was just teasing him. Having picked the flower, wouldn't throwing it away be a waste?
Xiao Hen then picked the flower back up and handed it to him, saying, "Here, I was just teasing you, it's not poisonous."
Xiaoba looked at the little flower with suspicion and did not reach out to take it.
The credibility of the bad brother-in-law was already gone; Xiaoba no longer believed what he said.
Thus, Xiao Hen held onto the flower for him, to prevent the kid from wreaking havoc on other flowers.
All the way, Xiaoba observed the bad brother-in-law, now glancing at his hand holding the flower, then at his face.
"Why do you keep looking at me?" Xiao Hen asked.
"I'm checking to see if your brows turn dark," Xiaoba said honestly.
Xiao Hen: "..."
It wasn't until they entered Renshou Palace that Xiaoba, seeing no signs of poisoning in the bad brother-in-law, finally took the flower back.
