There was an intense car chase between Loki and Maria Hill but Loki's car was able to get out of the tunnel. And at the mean time due to the collapse of the portal the whole facility was collapsing constantly. Maria who was trying to get out of the tunnel saw a huge concrete slab falling into her from up.
She knew that she would die in the next moment as there was no way she would be able to survive the fall. But what happened next surprised her. As the concrete block was falling they were stopped by a huge purple colored structure. On closer look it looked like a huge hand shining in blue light.
She turned around to see the source of this 'huge hand' only to see several agents covered and surrounded by huge structures that looked like rib cage of a person. On closer look she saw a man whose one eye was covered by hair.
She knew who saved her. It was Sasuke with his Susano. Even though she knew about the Susano but seeing the real deal up close was totally different than what the anime showed.
She got down from the car and entered the Susano. "Thank you." Maria said. All the agents who were saved were in awe and gratefulness in their face. Even though she had doubts about Sasuke's presence in such a hidden base but didn't say anything as Sasuke just saved her life.
Sasuke nodded at her and didn't say anything. He started walking while removing the rubble with his Susano while keeping the agents enclosed inside the Susano. After a couple of minutes they came out of the tunnel only to see that a hundred metres away Fury's chopper on which he had escaped was crash landing after being hit by Loki's energy beam from the scepter.
Sasuke who saw that after coming out of the rubble instantly vanished from his spot. He came near where the the chopper was going down and activated his Susano to catch the helicopter from falling down. The Susano instantly stopped the descent and slowly let the helicopter down saving everybody including the pilot.
Fury was relieved to see that he was safe but on guard too as he wasn't sure why Sasuke was here even though Sasuke saved him. This base was secured and a top level secret. But he finally managed to say
"Thank you for saving."
"You tried to control a power that couldn't be controlled. You have put humanity in danger Fury." Sasuke replied. Fury didn't refute Sasuke as he knew that trying to control the Tesseract was a danger in itself but he needed to take the risk.
Fury put on the radio and immediately ordered for high level emergency. Loki who was looking from far saw the Susano. He was surprised by this and asked Clint
"What is that?"
"From the far view it seems it's probably Susano from a guy named Sasuke. They belong to another world and they are really powerful. It will be your main hindrance in taking over Earth." Clint said in a straight face.
"They? What is this new world you are speaking about?" Loki was intrigued now.
"They belong to a new world which got merged to Earth few years ago. They are powerful ninjas with powers that can destroy cities and even Earth if they feel like it. The world council which is responsible for SHIELD is in a cooperative relationship with them" Clint replied.
"New world? When the hell did that happen? Heimdall never told anything about it. Are you sure of what you speaking is the truth?" Loki didn't believe at first.
"I have gone to their world and I have seen a glimpse of their powers so trust me on this. But they might not intervene in the invasion as they never really cared about Earth. Just don't antagonize them until you are sure you can obliterate them. They might not just care about you if you are lucky enough."
Loki now had a weird look in his face, even though he hasn't seen this so called new world, he felt a little fear. Though he wasn't sure if this new world was an illusion but that whole blue colored body projected by a man gave him chills, specially his eye. He could see his eye from a distance and that eye had weird sign on it and he felt extreme fear from that.
Even that guy who ordered him to come to earth didn't infuse that much fear into him. But Loki knew he couldn't turn back now.
"Let it be. I hope this new world doesn't interfere. As long as I can conquer Earth, the so called world won't be far away."
Fury on the other side saw Loki escape. He couldn't help but ask Sasuke.
"If he is a threat to humanity why wouldn't you stop him?" he asked
"It's your problem Fury. You created this mess, solve it yourself. Some people need a wake up call. Earth has been silent for a long time now." Sasuke who was walking away didn't even turn his head when he said that.
