Back then, Wei Heng saw through Xi Kun's greed. In order to prevent him from destroying the world order, he left his dual-time phone with Yuan Xia and asked her to remind her of herself a year ago to change everything. Unexpectedly, the call was picked up by Xi Kun.Xi Kun knew the secret of the mobile phone and coerced Wei Heng to no avail. It was not until many years later that Xi Kun ordered Pei Shen to steal Yuan Xia's mobile phone in an attempt to force Wei Ziqi to reveal how to use it.Wei Ziqi took advantage of the trick and handed over the fake mobile phone.In order to change Yuan Xia's death outcome, Wei Ziqi persuaded Yuan Xia to go abroad and took the risk himself.The two had their last date in a bookstore and used a space-time mailbox to send a postcard to each other a year later.The day before leaving the country, Wei Ziqi tricked Yuan Xia into signing the will in the name of going abroad materials. He transferred all his property to Yuan Xia and asked Xing Nan and Ni Ning to notarize it.The two had a warm and sweet birthday dinner in advance.After bidding farewell to Yuan Xia, Wei Ziqi immediately launched an action against Xi Kun.The call between Wei Ziqi and Xing Nan in the future time and space was suddenly interrupted. Xing Nan did not realize the warning and almost lost Wei Ziqi's life.Yuan Xia, who was in the future time and space, received a postcard from the mailbox of time and space. She scanned the code and heard Wei Ziqi's confession a year ago, and Yuan Xia burst into tears.
