Because it was the New Year festival, except for Gu Man who was pregnant, everyone drank a little, including Tang Haifeng.
Tang Haifeng was old and shouldn't drink, but he was healthy, so it wouldn't be a problem if he had a few cups.
Even if he really felt uncomfortable, Gu Ning could help him.
They had complete confidence in the effect of Gu Ning's medicine, since all of the members of the Tang family stayed in good health due to her power crystals.
Gu Ning left a bottle of power crystals in the Tang family's house, but they wouldn't take the pills every day. Normally, they would put a power crystal into the soup and would share it to keep themselves strong.
Otherwise, their bodies wouldn't be able to absorb the magical power and it might harm them.
