Tony turned to Thor and said, "Looking at the fighting on the ground, there was a fierce battle here, but it wasn't just one. Especially after that Red Skull guy died, there were still traces of intense fighting. Look at this scorched earth, it shows that the other party used electricity, because Captain wouldn't use this kind of attack. To be honest, I'm worried about him.",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."。
