At the very bottom of the building, there was a restricted area belonging to the Stark family. Even Tony had only been there twice. It seemed that painful memories were hidden here, leaving Tony unable to bear the thought… As they walked on, they reached an ancient room. Tony looked at the door and what came into view was a silver-gray spaceship. Its design was streamlined and its appearance was rather ordinary.,Rubbing his eyes, Guan Heng looked at the time-space shuttle curiously: "What is this thing" In the blink of an eye, the time-space shuttle landed on the ground. Three people came down from it, namely Iron Man in armor, Thor with a hammer on his waist, and Banner who was still a normal person.,A powerful force surged through his body, and a black dragon pattern instantly appeared on Guan Heng's chest. This was the mark of the Divine Dragon's Son, the inheritor of the Iron Fist!。
