A cute but brutal system.

Tai Heng was the closest son and the only one who dared to speak up in objection. 

"Father, I know you love your granddaughter so much but shouldn't you root for your grandsons too?" 

Grandpa Tai shoved Tai Heng away. He didn't move the slightest but his body swayed a bit and then righted itself. 

Then, the old man shamelessly said, "You are all old news. Xi Xi is the new spark in my eyes." 

"Ho!" the others responded. A few of them actually laughed. Their grandfather had gone crazy___, crazy for his granddaughter. 

Grandpa Tai was still not done with them. "Prove me wrong, if you think that you are stronger than her. Let's bring a concrete ball and see if you can break it at once with that big hammer. Heng, go online and buy a concrete ball." 

"Grandpa, I don't think anyone sells concrete balls." Tai Jiaan chimed in. 

Grandpa Tai genuinely looked surprised. "They don't." His tone was more questioning than stating.
