In 3033, when the Earth was home to humanity, scientific researchers developed a space converter to send modern humans to matching dynasties to resolve the pressure on the earth. A year later, an artificial intelligence companion system was developed, but there were still very few people who wanted to go. After all, everyone knew a little bit about the ancient environment. If the match was in troubled times, it would be a suicide.
"Finally, there is a major news broadcast. Quan Yu, the daughter of Quanda Technology, announced that she has matched the corresponding dynasty. She will leave the existing space at 8:25 on March 15th at the No. 1 Converter and return on March 20th. This proves the safety of space conversion and calls on everyone to contribute to the decompression of the earth."
