 Lana and her grandfather are searching for an IC chip in lower Industria which has a maze of tunnels. Lepka and his men have detected them on computer and sealing off any possible exits for them. They soon ended up at an enormous pit which leads to the Core Block. The lowest part of Industria. That s where they ll find an IC chip. Meanwhile Conan and Dyce try to fight off the Industrian members right till they retreated and head for Triangle Tower. Dyce is confused but is relieved that they retreated. Conan can tell that Lana & Dr. Lao have been detected so he heads on over there to save them. But he heard a voice from the prison, asking him if he could release them. He went inside and released all the prisoners, a man named Luke(a friend of Dr. Lao) tells Conan that he and the others were imprisoned because they were against Lepka. In return he ll guide Conan to where Dr. Lao is. On the way Jimsy joined up with Conan to help out. It was a long ways down but Lana and her grandfather made it to the Block Core. The place is dim, ruined, and old. The trees were rotted and the buildings were all damaged. Dr. Lao explained that this place was made as an underground shelter during the war. Everything was made to make it look like a city even an artificial sun to make it look like it s outside. Unfortunatly those who thought they be safe down here didn t last very long. 50,000 civilians died. 1,000 survived and those are the Industrians themselves. Lepka ordered his squad of men to infiltrate the Core Block. The committee didn t approve on Lepka not getting permission to use fire arms, but he ignored their warnings and told them it s the only way to get Dr. Lao by force. Luke lead Conan and jimsy through secret pathways that the Industrians don t know about. Conan and Jimsy discovered that there are a whole bunch of people who were against Lepka living in these secret hideaways. Conan was greeted and thanked by Luke s father(who resembles Conan s grandfather) for rescuing his own son. Conan gave thanks and couldn t help but addressing him as "Grandpa". Dr. Lao and Lana searched the old aircrafts for an IC chip. Lana finally found one, which will give the flying machine more power. Dr. Lao discovered that Lepka s squad team is here and tells Lana to go insert the Ic chip to the flying machine while he distracts them. He did and Lana went straight to the flying machine but was soon followed by 2 men. She was cornered and helpless right till Jimsy and Conan drop in to knock them out. Lana is relieved to see them both. Now they must get the flying machine ready and save Dr. Lao.
