"Father, why did my sister only leave with Jiande? Where is Jianguo?" Gao Gang's eldest son asked.

After hearing his son's words, Gao Gang reacted and said, "Shouldn't he go with his mother?"

"Husband, I didn't see Ah Shun bring Jianguo with her. She seems to have only left with Jiande," Gao Gang's wife added.

Not long after, they heard their grandson's voice coming from the backyard, "Grandpa, grandma, my cousin is dying! Please save him!"

Hearing this, everyone stood up in shock and rushed to see what happened. When they arrived in the backyard, they saw Chen Jianguo lying on the ground unconscious. His collar was stained red by the blood from the back of his head.

"What happened to him?!" Gao Gang asked with shock.

"Grandpa, I came back from school and saw my cousin lying here. The back of his head was bleeding!"

"Husband, take him to see a doctor quickly!" Gao Gang's wife said in panic.
