Ning Zheng's consciousness returned to the Sword Casting Manor.
"Reincarnated, wait for him to grow a few years."
Ning Zheng picked up his teacup and thought for a moment, "Probably, it only takes less than the time it takes to drink a cup of tea."

The time of a cup of tea passed quickly.
At this time, Jian Xin had already been born and completed a harsh and rigorous childhood.
Because of the Celestial Destiny Night Emperor's educational policy, the children in this world suffered greatly and were very tired.
But fortunately, the human race in this world has also been blessed with optimization, born with early wisdom.
They only need to sleep for three hours to recover their spirit, be energetic, and love studying and cultivating every day.
Everyone is naturally industrious.
