Loud shouts, noisy footsteps, and blinding flames erupted from the muzzles of guns.

"What is this place?"

Sean opened his eyes in a trance, and his consciousness resurfaced, as if he had just woken up from a dream.

He saw a dense number of bullets hitting his body, and the metal bullet casings carrying strong kinetic energy seemed to hit a copper wall, and the bullet head seemed to be squeezed by a huge force, and it deflated directly.

His gaze shook a few times, perhaps stimulated by the outside world, and his drowsy mind gradually cleared up, and he tilted his head slightly, observing the surrounding scene.

The air is filled with cloudy dust, overhead are incandescent light bulbs illuminating the dimly lit environment, and the walls are covered with intricate cables and pipes that appear to be fortifications or secret bases built underground.

"What happened?" A second question popped up in Sean's mind.

He'd never been in a trance, confused, like a hangover rotten drunkard waking up the next morning with a splitting headache, fragmented memories, and everything that had been before forgotten.

Sean came to this world, never relaxed his inner vigilance, with his physical fitness, he was completely immune to the invasion of alcohol, and it was impossible for him to get drunk for a while.

Even after drinking vodka from a cellar, he may not feel "drunk", and it is impossible for him to forget what happened before.

"Sentinel ......"

He lowered his head, he was in the golden armor, and the torrent of metal that tore everything apart couldn't cause any damage, even if the energy force field didn't even rise, those sharp bullets that pierced through the human body and tore through the flesh and blood felt a slight itch on the body.

"Hydra."

Sean saw the group of soldiers in black uniforms with the Hydra badge on their chests, and as if he remembered something, he raised his right hand and carried a suitcase on it.

The gaze looked through the shell, and a huge blue halo was released from it, and it was...... Cosmic Rubik's Cube?

Consciousness kept backtracking, the groggy feeling receded like a tide, and Sean finally regained his awake brain, and his fast thoughts were like lightning flashing by, instantly piercing the fog in his mind.

Loki took the Hydra team to try to get the materials to make the reactor from Ambrera, and then the Umbrella team wiped them out, and changed his mind to get the Infinity Stones first and welcome Thanos in advance......

So, this is Hydra's secret base?

Through Skynet's surveillance, he found the secret base where Hydra was hiding, broke in all the way, and took the Cosmic Cube from Dr. Servig's hands?

Before Sean could answer the barrage of questions, he heard the subtle sound of the barrel of a gun turning, and a group of Hydra agents armed with heavy firepower weapons rushed wildly from the underground passages in all directions, accompanied by a thunderous roar, dazzling tongues of fire flickering, like the breath of a dragon, and the hot iron stream engulfed the golden figure standing still.

Like a raging rainstorm! Like a thundercloud! Like an exploding sun!

The barrel of the gun spun like the rudder of a clock, and the bullets poured out of it, spraying with unimaginable speed, and the thunderous roar vibrated the eardrums as if in a thunderstorm cloud of riot.

Even a two-finger-thick steel plate will be crushed into powder in such a fierce fire!

Command Post 1 at the Underground Base, where the Hydra Commander is John Garrett, a high-level spy embedded within S.H.I.E.L.D., is tasked with helping Loki implement his plans, stirring up more chaos, and incidentally obtaining intelligence information about Asgard and alien technology.

Hydra knows more about the Cosmic Cube than S.H.I.E.L.D., and the leader of World War II, Red Skull, developed infinite energy and advanced weapons, and nearly won the grand war that swept the world in one fell swoop.

Therefore, Garrett has always focused on Dr. Servig, and when the intruder appears, he sends people to protect them, and in less than ten seconds, these elite warriors are all cold corpses.

"Sentinel?" Garrett asked in a deep voice.

Dozens of surveillance personnel are busy with a clear picture of the miniature cameras scattered throughout the underground base, and hundreds of screens form a wall, which is not only used to alert intruders and observe everything going on, but also to monitor Loki's every move, and even directly manipulate the weapon system inside to carry out precise strikes anytime, anywhere.

"Confirmed to be a sentry once seen in New York." A Hydra agent replied.

"Turn on the active defense system and organize all forces to block the passage! The rest of the districts were quickly evacuated, and if necessary, cruise missiles could be used for carpet bombing! ”

Garrett's heart sank, the file about the Sentinels had a high privilege in S.H.I.E.L.D., and was classified as a high danger level, on par with the latest addition, Hulk. In the face of a terrifying existence of this level, he could only do everything possible to stop the other party's actions.

But after the frontal baptism of the metal storm, no matter how strong the creature is, it will be seriously injured, right?

"He's alive! He moved......"

The sound stopped abruptly, and there was a dead silence in the monitoring room, as if everyone had been choked by the neck.

If time slows down and becomes a frame by frame slow motion, Garrett can see the hot iron jets spewing out of the spinning barrel, the air along the way seems to be burnt, emitting a scorched smell, and the golden-red light forms a sharp cutter that shatters any obstacle in front of him!

And the golden figure standing still took a step forward, and the underground passage echoed with a huge tide of thunder, like an angry wave rolling and trembling!

Countless dust splashes, the unstoppable stream of hot iron suddenly stagnated, the space seemed to freeze, and then the next moment-

The powerful force erupted like a volcano, and the fierce momentum broke through the solid passage, and in the rumbling loud sound, thousands of metal bullets wrapped in thick fireworks rolled back like ocean waves!

The passage in front of him collapsed in an instant, and golden red fireworks erupted, and the Hydra agent was directly crushed into a mess of mud, and he couldn't even see the human form.

The sentry took another step, countless fine dust spread in ripples, huge cracks opened on the ground, and violent energy swept out, and the compressed air exploded like cannonballs!

The fortification, located 40 meters underground, is said to be able to withstand 125 tons of ammunition, and the walls around it are reinforced with hundreds of meters of granite, special concrete and steel plates, which can absorb the shock wave generated by the missile bombardment, and even if a large-yield hydrogen bomb is dropped, it is enough to sustain it.

However, under the impact of the sentinel's energy, the air seemed to be detonated by countless powder kegs, and the entire underground base shook and trembled, even Garrett, who was far away in the monitoring room, could feel it, and the hundreds of screens on the walls were dimmed one after another, flickering with dense snowflake spots.

"Retreat! Give up the stronghold! Garrett hurriedly ordered.

He didn't know why the sentinels wanted to seize the Cosmic Rubik's Cube, but judging from the current situation, Hydra would definitely not be able to stop the other party's actions, and instead of consuming strength, it was better to evacuate as soon as possible.

"Start the self-destruct system!"

Before leaving, this rough cowboy old and hot agent did not give up the idea of killing the sentry.

Once this underground base is destroyed from the inside, the stored missile launch system will automatically detonate, and it will be directly buried by hundreds of tons of soil, even if it is a monster like Hulk, the survival rate is probably extremely low.
