Treasure Identification Mobile Phone

Xu Dong, a senior majoring in cultural relic restoration, When I was about to graduate, I explored the ancient city with my tutor and got a mobile phone. Identify the treasures of the past, predict the treasures of the future, and search for treasures of heaven and earth... A magnificent and gorgeous world appeared in front of Xu Dong, completely subverting Xu Dong's world view and embarking on a completely different path. What a magical machine!
