Even after Cao Jiajun got drunk at his place, he still made threats, "I'm your brother! Your own brother! Why can't you help me?
You took me to the casino, so you have to be responsible! I still owe eight hundred thousand now, can't you just give me that little bit?
My house is for our parents, either you sell the house, it can definitely go for over a million, or let your wife go sell it!
In a couple of years, when your daughter grows up, Cao Jiahao, you'll be loaded, with two women at home earning money for you. What's wrong with giving me eight hundred thousand now?"
Cao Jiahao then started having other thoughts.
He didn't originally intend to kill Cao Jiajun, he just heard of a drug that could make people obedient, and he wanted to use this chance to record Cao Jiajun's misdeeds.
But unexpectedly, Cao Jiajun hallucinated that his child was a debt collector, and under the influence of that, the two fell off the building together.
