Summon the Villain: Marvel.

time flies.

Nathan Hawke was currently at Umbrella's newly built large combat test site, watching the battle inside.

In the battle experiment field, the battle atmosphere between Kamen Rider Ark and Kamen Rider Duke was tense and fierce.

The venue was simulated as a city street, with the ruins of skyscrapers and dilapidated buildings scattered around. The bright neon signs of the city were extinguished at this moment, leaving only the dim halo of street lights. This environment seemed to announce the arrival of a major showdown.

Kamen Rider Ark looked mechanical and unique, standing tall, scarlet light gushing out of its single eye, stinging people's eyes. Its body was covered with metal armor, exuding a cold breath, like a mechanical god of war.

The Kamen Rider Duke on the other side was wearing gorgeous armor, a crown on his head, and holding a gilded sword. He looked tall and mighty, like the ruler of an empire, with an imposing manner.

The two faced off in the middle of the city street, and for a moment, it was dead silent, with only the sound of the breeze blowing through the ruins.

Kamen Rider Ark's movements are smooth and precise, like a mechanical precision instrument. Its single eye constantly scans the surrounding environment, using the computing power of artificial intelligence to predict every attack of Kamen Rider Duke. Ark's metal armor flickers in the light, emitting a cold glow. Its attack is full of technology, and laser beams spurt out from the launch port on its arm, instantly cutting through the ruins of the city, forming a light curtain, trying to trap Kamen Rider Duke.

Kamen Rider Duke relied on his strong fighting instincts and reactions to fight against Ark. His armor was extremely strong and his swordsmanship was superb. Every swing of his gilded sword brought a strong pressure. Duke's attack was like a storm, sweeping in, blasting the ruins and scattering rubble. Every swing of his sword seemed to have infinite power, trying to penetrate Ark's metal armor.

The battle between the two was fast and intense. Ark's calculation ability allowed him to accurately dodge Duke's attacks while accurately shooting at the highly accurate lasers. Duke, with his excellent fighting skills, kept approaching Ark, trying to crush his opponent with his strength.

The ruins of the city streets had suffered severe damage from the battle between the two, with buildings collapsing and sparks flying.

Ark's single eye flashed scarlet, and its computing power allowed it to predict every move of the Duke. Although its attack was not as powerful as the Duke's, it was extremely accurate. The laser beam penetrated the air, cutting out lightning-like rays, trying to restrain the Duke.

Kamen Rider Duke leaped up and blocked the laser beam fired by Ark with his sword. The light collided with the light, forming a dazzling fire. He landed on the gravel in the air, his eyes as sharp as an eagle, staring at Kamen Rider Ark intently.

Ark did not stop attacking, its one eye glowed even more fiercely, quickly calculating its next move. Suddenly, Ark's metal arm quickly deformed and turned into a curved blade, slashing at Kamen Rider Duke like a chainsaw.

The Duke used his sword to block Ark's blade, but Ark did not stop. His metal arm transformed again, turning into a huge iron hammer, and hit the Duke hard. The Duke dodged, but was still lifted up by the aftermath of the hammer and fell into the ruins.

Jacques quickly caught up, his metal arm transformed back into normal form, used to perform a deadly attack. The Duke climbed up, sword in hand, and withstood Jacques's blows. The two swords crossed each other, and each swing brought a powerful force. The two swords crossed each other, and each swing brought a powerful impact.

The metal arm of Ark was like a unicorn's horn, constantly shuttling through the air, forming lightning-fast attacks. The Duke used his sword to block every attack of Ark, but his armor had been obviously damaged by Ark's blows, with fragments flying and sparks flying.

The Duke knew he had to find an opportunity, otherwise the battle would be unfavorable to him. He concentrated his energy and waited for the next attack from Ark. At that moment, Ark's metal arm suddenly split into several thin tentacles, which wrapped around the Duke's sword like an electric python and bound it tightly.

The Duke felt a powerful force coming towards him, trying to take the sword from his hand. He struggled with all his strength, but the tentacles were getting tighter and tighter, and he felt that his sword was about to be taken away.

The single eye of Ark flashed scarlet, as if mocking the Duke's struggle. Its computing power allowed it to predict every move of the Duke, including resistance. The tentacles tightened, and the Duke felt unable to break free.

Suddenly, the Duke's eyes became firm and bright. He gathered all his strength and suddenly shouted. A powerful light burst out from the sword tip. This light was like lightning, instantly shattering the tentacles and saving his sword.

The battle between Kamen Rider Ark and Kamen Rider Duke has reached a fever pitch. Both have demonstrated their strong strength and tenacious fighting will.

To this end, they decided to unleash their respective special moves to put an end to this battle.

\"Kamen Rider Ark...\" Ark's metal arms quickly separated and turned into tentacles that glowed red. It stretched these tentacles toward the sky and began to spin, forming a huge vortex. The red ball of light in the center of the vortex glowed with a fiery light.

Yak raised his hands above his head, palms facing upwards, stretched out his tentacles, and tilted his body slightly upwards, ready to release a huge amount of energy. His posture was like a mechanical war god with a red halo.

\"Crimson Vortex!\" Ark's voice sounded in the unique mechanical sound effects, and the light ball burst out with fiery red energy, forming a powerful gravitational field. The rubble and debris in the ruins were sucked into the vortex, forming a huge whirlwind, like a meteor streaking through the night sky. The red vortex swept in like a flame, and violently rushed towards Kamen Rider Duke.

\"Kamen Rider Duke...\" At the same time, the armor on Kamen Rider Duke's body emitted a brilliant golden light. He held the sword in both hands, raised the gilded sword above his head, stood on the top of the ruins, and stared at Ark.

"Royal Wrath!" The Duke's voice resounded throughout the battlefield, and the brilliant golden light of the sword blended with the brilliance of the armor. His posture was like that of an empire king, standing at the top of the battle.

The red flame vortex of Ark and the royal wrath of the Duke were heading towards each other. The two powerful energies collided with each other, making a deafening explosion.

The red light of Ark's vortex was blazing, burning like a raging fire, while the Duke's Royal Fury emitted a shimmering golden light, like a waterfall of gold.

The energy conflict between the two created a chaotic spark in the air, and energy fluctuations spread wildly. The city ruins suffered even more severe destruction, and the buildings were completely razed to the ground.

Both Ark and the Duke were trying their best to release their ultimate moves, stimulating each other's strength to the extreme. The two figures were looming in the energy fluctuations, like a duel between the God of War and the Emperor.

As time went on, the energy fluctuations between the two became more and more violent, and a huge vortex formed in the center of the venue.

......

The battle is over.

Looking at John Walker who came out with a face full of sweat, Nathan Hawke smiled and applauded, saying, "Thank you for your hard work. It was a great fight."

John Walker was surprised to see Nathan Hawke waiting for him at the exit, and said quickly, "It's not hard, it's not hard."

"Haha, I told you, John is very strong now. If his blue form, Duke Azure, is activated, Ark will not be his opponent at all." Zhan Ji Lingma also came over, raised his eyebrows and looked John Walker up and down, then joked, "You look a lot more handsome now."

John Walker nodded somewhat at a loss, not knowing how to respond to Zhan Ji Lingma's teasing.

Nathan Hawke couldn't help but laugh when he saw this scene. If it was John Walker who became Captain America in the future, he would have definitely hit him with the shield. He would not have grown into maturity on the immature path like he is now.

"Go to the medical room and rest." Nathan Hawke patted the other person's shoulder and found that the heat on the other person's shoulder was surprisingly strong.

"Go ahead." Zhan Ji Lingma also said.

"Okay, then, Boss and Doctor, I'll be leaving first." John Walker still felt a little dazed when he left.

After John Walker left, Nathan Hawke raised his eyebrows and asked, "I just tapped his shoulder. What did you inject into his body?"

Zhan Ji Ling Ma knew what Nathan Hawke was going to ask.

Zhan Ji Ling Ma began to narrate this special process: "Boss, Duke Azure's power comes from the blessing of the azure secret, but this power is still unbearable for John. Although John's body has been strengthened, to fully control this power, a stronger body endurance is required."

Nathan Hawke nodded and indicated that he should continue listening.

Sengoku Lingma continued to explain: "So, I made some adjustments and injected the medical data we collected in the 2077 world. The synthetic formula in it plus our original human gene virus excellent fluid strengthened his physical fitness and made him more adaptable to Duke Azure's power. But this is not enough. I also added the desperate virus to it. This is to stimulate his potential, the potential when his body is torn apart, so that he can release more power in critical situations."

Nathan Hawke frowned slightly and said, "You are playing with fire." Zhan Ji Lingma was playing with fire in every sense of the word.

"Are you sure this is okay?" asked Nathan Hawke, worried that the decision might have unintended consequences.

Zhan Ji Ling Ma nodded and replied: "I have made some modifications to the Extremis virus to create a balance between it and other viruses so that it will not cause too many problems. In addition, I will continue to monitor John's condition to make sure everything is under control."

Nathan Hawke pondered for a moment and nodded: "Okay, I believe in your decision. As long as you don't fail at the critical moment, I will fully support you."

Zhan Ji Ling Ma breathed a sigh of relief, he knew that his decision was not rash, but he believed that it was for the greater good.

At the same time, this scene also reminded Zhan Ji Lingma of that man.

Takatora Wudao recalled the days when the two worked together.

Watching Nathan Hawke's departing figure.

Sengoku Lingma turned his head and looked at the traces left by the battle between Kamen Rider Ark and Kamen Rider Duke.

He murmured, "Gui Hu, he is also a rare good boss."
