Although the entrance to the base is disguised as a rock in the snow, the rest of the base was located below the surface because of concealment.

Hill knew the danger of fighting in the basement, especially when the ground was still covered in ice and snow, and might repeat the tragedy that happened a year ago at the S.H.E.L.D. Accelerated Test Center. Although Loki just took the Cosmic Cube and left, the subsequent collapse of the base caused heavy losses to the employees, including their own lives.

"Then the question comes." Stark, who had been silent for a long time, finally had movement. He stared at a veteran of World War II with a bright look and asked, "Barnes? I'm curious where you came from and how you got these five bags of serum?"

"Ahem, Mr. Barnes." Fury tried to change the subject and struggled, "You need us to develop rehabilitation training for you..."

"Fry?"

Before Fury finished speaking, Stark's frivolous tone sounded from his ears, followed by his unconcealed gaze with a strong warning. Hill, who had originally wanted to say something, tightened his hand holding the gun, but finally didn't speak.

"Yes, of course, thank you." Bucky nodded slightly at Fury, then shook his head, which had been struggling to think about because of digesting memory, and continued to answer, "That was a mission on December 16, 1991, 'Sanctions and Retrieval'. At that time, Hydra sent me to get the stolen scientific research results, that is, the serum."

As he said, Bucky suddenly thought of what the black man had just said, so he turned to the direction of the metal man in front of him. He saw him tilting his eyebrows into a horoscope, as if searching for the scene in his memory: "Wum—It's a coincidence that the target was also called Stark, but it was not Tony Stark. I remember that it seemed to be called Howard or something? Now more people in our country's surname are Stark?"

Kakka--

Before Bucky's voice could be completely finished, everyone present heard a high-frequency mechanical operational sound that was difficult to describe completely in onomatopoeia.

"(??ˇ?ˇ?)づ Hey!" Yi Song quickly put on a "stop" gesture, "Don't be impulsive, Mr. Stark."

However, Stark's steel suit did not stop there, and a warning sound mixed with electronic synthesizer came from the iron shell that kept walking: "No one can stop me from taking revenge, so do you, easy."

"Sir, what's going on?" Seeing that the Avengers came forward to stop him, Hill quietly pulled the director's hem of his clothes, "What's the revenge?"

"Let's take a look first." Fury, who was also not worried, had no fluctuations in his heart at the moment, and even made a joke, "Maybe the old case that SHIELD has been covered in for more than 20 years will be solved today."

Fury's greatest source of confidence is Yi Song. Judging from the tests he had seen with the opponent over the years, Fury thought he still knew Yi Song's abilities. Not to mention his terrible intelligence information, even the record of Yi Song's single-killing nuclear bomb in New York has made Fury feel sincere at this moment - Yi Song seems to have a lot of experience in the defense of thermal weapons.
