He Said That He Had Passed Down the Exercises from His Family, and He Actually Gave Me a Mobile Phone!

In the year 3023, I went back to my hometown to sweep the tomb, opened the small door that I had sealed with cement in the secret compartment of the ancestral hall, and took out the family secret treasure buried by my ancestors in 2023 AD. This is a small box made of unknown materials. It has not decayed after five thousand years. It is incredible! I prayed silently in my heart, hoping that it would be the peerless skill I needed. I would use the power of my ancestors to kill all the monsters and rebuild the glory of the Wang family. It is our duty to do so! To go too far, the whole family has withered and I am the only one left. If I can't stand up anymore, I will really be extinct! I opened the little box... What is this? A hand... Cell phone? !
