Summon the Villain: Marvel.

The skillful battle between Captain America and Viper 1 was like two dancers dancing on the battlefield. Their movements were graceful and precise, and every swing of the sword was devastating, yet it was like a gorgeous ballet. In that dark and damp basement, the battle became a stage full of light.

Captain America and Viper 1 have fought for dozens of rounds, and each can feel the strong pressure emanating from the other. Their strength is extraordinary, and the sparks from their swords during the battle can even ignite the rotten paper on the ground.

Viper 1 attacked fiercely, and each of her strikes was swift and accurate. She used rapid and continuous attacks to try to break Captain America's defense. However, Captain America responded calmly, using his flowing body to dodge the enemy's attacks and using his shield to continuously repel Viper 1's attacks.

"You're nothing but that!" Viper No. 1 shouted through gritted teeth.

Captain America did not respond. He focused on the battle, looking for Viper 1's flaws. As the battle progressed, he gradually figured out the opponent's attack methods and habits. Although Viper 1 was fierce, she was not good at fighting for a long time, but was better at quickly solving the enemy.

"I have to find an opportunity!" Captain America decided secretly.

At this moment, a slight chance appeared. Viper 1's attack missed slightly, leaving a brief gap. Captain America immediately seized the opportunity, dodged and rushed forward, sword and shield intertwined, launching a series of continuous attacks.

Viper No. 1 was forced to take several steps back, but quickly adjusted his posture and used his sword to neutralize Captain America's attack. She sneered: "It seems that you are not qualified to fight me."

"I can fight this kind of battle all day long," Captain America said firmly.

He stomped his feet hard on the ground and rushed forward. Viper No. 1 hurriedly raised her sword to block, but was troubled by Captain America's sudden change of tactics. His sword drew an arc from bottom to top and hit Viper No. 1's lower body, knocking her off balance.

Captain America did not miss this opportunity and launched another fierce attack. His sword moves were continuous, and each move was like a sharp blade, accurately pointing to Viper No. 1's vital points.

Viper No. 1 was immediately in a passive position. She kept swinging her knife to block, but she couldn't get away. Captain America's combat experience and skills enabled him to suppress his opponent in a short time.

The agents were delighted when they saw this scene. They knew that Captain America had extraordinary strength and endurance, and as long as he was given time, he would surely win.

However, Viper No. 1 was not willing to be defeated. She suddenly rolled sideways, turning the passive situation into active one, and dodged Captain America's attack with her agile body.

"You are still too young." Viper No. 1 said sarcastically.

Captain America was not discouraged, he knew that the battle was far from over. His eyes became more determined, and the super serum in his body flowed through his body, providing him with endless power.

Viper No. 1 attacked again and fought Captain America again. The sound of their swords clashing was deafening, and their figures quickly shuttled through the basement.

In the darkness of the basement, the battle was in full swing. The skillful battle between Captain America and Viper No. 1 made the whole scene full of tension and intensity.

Suddenly, a group of desperate warriors appeared on the battlefield. They exuded high-temperature energy, like the scorching sun. These desperate warriors had amazing firepower and could release high-temperature energy attacks at close range.

Black Widow, Melinda May and the agents immediately realized that the crisis was intensifying. The appearance of the desperate warriors made them feel unprecedented pressure.

The desperate warriors used their high-temperature energy to launch an attack, and high-temperature beams shot towards Black Widow and others.

Black Widow, Iron Knights and agents suddenly felt unprecedented pressure. They were suppressed in an instant and had to deal with the attacks of the desperate warriors with all their strength.

"Be careful! Their attacks are extremely destructive!" Black Widow warned.

The agents immediately dispersed and used the structure of the room to find cover. The high-temperature energy attacks of the desperate warriors swept across the battlefield indiscriminately, and the battlefield instantly fell into chaos.

Black Widow, Melinda May and the agents were besieged by desperate warriors. High-temperature energy beams continued to destroy the battlefield, making it impossible for them to fight in close combat. At the critical moment, a dark figure quickly appeared on the battlefield. It was the leader of the Shadow Cult, Zed, who wanted to be a superhero.

Jie glanced around indifferently. He was wearing a black shadow outfit, holding a fist sword, and exuding an evil aura.

"This person is!" Black Widow exclaimed in a low voice.

The appearance of Jie made the desperate warriors pause for a moment, but soon they launched another attack. Jie looked at the desperate warriors in front of him coldly and officially entered the combat state.

"The invisible blade is the most deadly."

"Shadow Ninja Technique! Soul-Destroying Jie!" Jie moved quickly to avoid the high-temperature energy attack. He aimed his fist sword at a desperate warrior, and each strike was extremely accurate and deadly. When his fist sword touched the already seriously injured desperate warrior, Jie's attack became even more deadly, invisible like a shadow, making the enemy's life even more fragile.

"Shadow Secret! Blades!" Jie and his shadow clone suddenly threw the swords and shuriken in their hands forward. The swords spun rapidly, forming a rain of swords that covered a large area of ​​the battlefield. The desperate warriors were forced to dodge everywhere, but several of them were still hit and instantly caught fire.

"Shadow Secret! Clone!" Jie's figure suddenly split, and several shadow clones appeared. These shadow clones would imitate his skills, increasing his combat effectiveness. They quickly shuttled across the battlefield and fought with the desperate warriors.

With his superb combat skills and mysterious shadow form, Jie is like a dark wind, quickly shuttling across the battlefield. Each of his attacks is like a deadly venomous snake, making it difficult for the enemy to predict. He uses the cooperation of his shadow clones to sometimes dodge the enemy's attacks, and sometimes quickly approach the enemy to launch another deadly attack.

"Forbidden Secret! Instant Prison Shadow Killing Formation!" Jie suddenly became untargetable, and quickly rushed towards a desperate warrior, marking the target. This rush was accompanied by a dark blade light, which was dazzling. Three seconds later, the mark was triggered, causing terrible damage. At the same time, the shadow clone left by Jie swapped positions with the target.

The appearance of Zed changed the situation dramatically. His attacks were like lightning in the dark, fast and deadly. The desperate warriors began to suffer heavy losses, and the siege on them gradually loosened.

At the same time, the invincible posture of not looking back at the fallen enemy also shocked Black Widow and her group.

After the shock, Black Widow, the Iron Knights, and the agents seized the opportunity to use Zed to disrupt the Extremis' formation and began a counterattack. Zed's presence created a brief moment of respite for them, and they launched an all-out attack, quickly reducing the number of Extremis.

While cooperating with his shadow clone, Jie was looking for the weaknesses of the desperate warriors. His fist sword was like a beast in the dark, mercilessly shattering the high-temperature shields of several desperate warriors and then killing them.

"Embrace the shadow...or die in the darkness." Zed's voice was cold and firm.

Under Zed's leadership, Black Widow, Melinda May, and the agents gradually took control of the battle. Zed's presence helped them regain hope of victory, while the desperate warriors fell into unprecedented despair. Zed was like a dark star on the battlefield, dazzling and destined to lead the enemy into despair.

In the collision of high-temperature energy and shadow ninjutsu, the situation on the battlefield gradually became clear, and the appearance of Jie completely changed the situation. With his invisible killing intent and fierce attacks, he killed the desperate warriors one by one. The dark shadow shrouded the battlefield, and the bloody breath filled the air, but Jie was unmoved. He continued to move forward and constantly defeated the enemy until the battlefield returned to peace again.

When the battle was over, Jie stood in the center of the battlefield, with a dark atmosphere surrounding him. His eyes were cold and firm, without any sadness or joy.

Black Widow, Melinda May, and the agents looked at Zed with awe in their hearts.

On the other side, Viper 1's offensive was completely suppressed by Captain America, and she felt helpless as victory was fading away. She looked across the battlefield and realized that the current situation was extremely unfavorable to her, and the disadvantages of the desperate warriors had become obvious.

"Damn it!" Viper No. 1 gritted his teeth, feeling anxious.

An idea flashed through Viper 1's mind - retreat. On the battlefield, sometimes knowing when to retreat is a wise choice. She calmly analyzed the situation and found that she was forced into a passive situation.

She made a quick decision and temporarily gave up the direct confrontation with Captain America. She turned around and quickly retreated, trying to find an opportunity to retreat. Viper No. 1 knew that in this kind of battle, she didn't have much time left.

Captain America saw Viper 1's movements and knew that the other party was looking for a chance to escape. He did not rush to chase him, but instead stood firm, kept a certain distance, and was ready to respond to possible attacks at any time.

Viper 1 is like a nimble snake, swiftly shuttling across the battlefield, using battlefield structures and obstacles to conceal its whereabouts, constantly changing direction to make it difficult for the enemy to track it.

"You can't run away!" Captain America's voice came.

Viper No. 1 did not answer, she knew in her heart that only by surviving could she come back for revenge. She continued to flee at all costs, trying to get rid of Captain America's pursuit.

However, Captain America did not intend to let her go. He followed closely behind, always keeping alert to prevent Viper 1's sudden attack. Viper 1's skills and speed made him feel exhausted, but he did not give up, knowing that as long as he could chase Viper 1 to a suitable position, he would have a chance to defeat the opponent.
