Lu Fan was currently having a silent competition with one of the most distinguished figures out there.
Han Huang the Empire's prime minister.
Han Huang had served the previous Emperor and was still serving the current one while his age mates had retired long ago.
But that was not important to him.
Han Huang had come on Friday thinking that he would find Lu Fan and his granddaughter around, but he found that they had gone on a trip.
That made him regret not informing anyone of his visit but it also gave him a good excuse to stay out of office for some time.
And when Han Zu Xuan came back yesterday at noon, she showed him things that he always thought would take at least twenty years to develop.
People were researching VR/AR technology and there was progress, but it had yet to reach such absurd levels.
