Time flies, three months have passed in the blink of an eye! This group of friends held a meeting at Tony's lair—Stark International Tower. Attendees include Iron Man, Hulk, Thor, and Black Panther.,It's unclear if it was due to the Super Serum, but Guan Heng's progress was abnormally rapid. His physique grew increasingly strong and robust. In less than a year, he had mastered all the martial arts skills. In his own words: "This kung fu stuff is the easiest for me to learn, after all, it's something unique to my homeland!",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!。
