He hadn't mentioned it himself because he wanted to wait for Dad to come over. After entering the facial recognition and fingerprint directly, he might bring up the password afterward.
Once the face and fingerprint had been input, the password had actually become somewhat superfluous.
"Disappointed to see Dad?" Zong Ji glanced at Zong Guang's face.
"How could I be?" Zong Guang explained, "The house was just renovated, and little brother happened to be on vacation and came over. I thought that Dad and brother meeting might be a bit awkward, so I didn't have Dad come over for the housewarming."
"Housewarming." Zong Ji looked around and said, "That term is completely unrelated to the situation now."
"We had the housewarming yesterday, and it was quite nice." Zong Guang added.
"Where's your liquor? Dad bought lots of food to cook something delicious for you so that we father and son can drink to our hearts' content later." Zong Ji quickly switched into chef mode.
