The Dilong (earthworm) drilling team has achieved countless supreme honors for the country and mankind in terms of earthquake early warning and obtaining underground resources. However, foreign forces have set up a trap to implant viruses in the Qianlong sensors deployed by the Dilong drilling team in the deep strata, causing the Dilong 7-23 to drill 27 kilometers underground on the seabed near Donghai Island. The Dilong 7-23 arrived 25 kilometers underground, in order to reduce the risk, two team members, Ren Feiyang and Zhuge Feifan, were sent to drive a smaller MINI to detect important information. When the two team members arrived at the information location, they were entangled in the high magnetic grid deployed by the enemy. When Ren Feiyang woke up, he found himself naked, but saw ancient armor nearby, so he had no choice but to put it on and leave. After a few days, he discovered that he was in another world. The armor seemed to be his, and he seemed to have traveled to the Spring and Autumn Period and the Warring States Period. Sure enough, this new world was exactly when Qin and Chu were fighting for hegemony, but the characters in it were not the same as what was recorded in history. Ren Feiyang was so impatient that he didn't know whether he had traveled through time or had lost his mind and couldn't remember history. It wasn't until one day when he was being chased and fled into the deep sea that he discovered a phenomenon. This phenomenon told him that this was not the Warring States era in history, and he was not traveling through time. This was the world in the center of the earth.
Purpose: The high-tech Dilong 7-23 drilling vessel allows humans to predict earthquakes in advance and reduce the huge losses caused by disasters.
