Putting on a serious expression, Tony stated solemnly, "Speaking of vibranium, Captain America's shield has also vanished. Even the miniature nano tracker I had installed in the gap between his shield plates for precaution hasn't reacted at all. Moreover, the body wearing the Red Skull uniform encountered an issue. During transportation to the laboratory for analysis, it rapidly decomposed into ashes. My experts are unable to confirm if it was indeed the Red Skull.",Black Panther flipped through a stack of data on the table: "Besides, the letter we found on Captain's desk before has been proven to be written by Red Skull himself. Of course, Captain knew this, which is why he went alone to settle the score.",Hulk punched Thor square in the face, causing the latter to release Guan Heng instantly. At this moment, Tony's syringe also plunged into Guan Heng's neck!。
