Time passes.

Nathan Hawke was at the new large combat testing ground under the umbrella at this time, watching the battle inside.

In the Battle Proving Ground, the atmosphere of the battle between Kamen Rider Ark and Kamen Rider Duke is tense and intense.

The site is simulated as a city street, with the ruins of skyscrapers and dilapidated buildings scattered around. The glowing city neon signs are now extinguished, leaving only the dim glow of street lights. This environment seems to announce the arrival of a major showdown.

Kamen Rider Ark stands tall and mechanical and unique, scarlet light gushing out of its single eye, stabbing people's eyes. Its body is covered in metal armor and exudes an icy aura, like a mechanical god of war.

The Kamen Rider Duke on the opposite side is dressed in gorgeous armor, wearing a crown and holding a gilded sword. His image is tall and mighty, like the ruler of an empire, and he is imposing.

The two faced each other in the middle of the city streets, and for a moment it was as silent as death, except for the sound of the breeze blowing through the ruins.

Kamen Rider Ark's movements are smooth and precise, like a mechanical instrument. Its one-eyed constantly scans its surroundings, using the computing power of artificial intelligence to predict every attack of Duke Kamen Rider. Ark's metal armor shimmered in the light, emitting a grim glow. Its attacks are full of technology, and laser beams erupt from the emitter on its arm, instantly slicing through the ruins of the city, forming a light curtain in an attempt to trap Duke Kamen Rider.

Kamen Rider Duke relies on his powerful fighting instincts and reflexes to fight against Ark. His armor is sturdy and his swordsmanship is superb. Every swing of the gilded sword brought a powerful oppressive force. The Duke's attack swept in like a storm, blasting the ruins apart and scattering rubble. Each swing of his sword seemed to have infinite power, trying to penetrate Ark's metal armor.

The pace of the battle between the two is fast and intense. Ark's computing power allows him to accurately dodge the Duke's attacks, while firing lasers with extreme accuracy. The Duke, on the other hand, relied on his excellent fighting skills to keep closing in on Ark, trying to crush his opponent with his strength.

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

Ark's one-eyed flickered crimson, and its computing power allowed it to anticipate the Duke's every move. Its attacks are not as powerful as those of the Duke, but they are extremely accurate. Laser beams pierced the air, cutting lightning rays in an attempt to bind the Duke.

Duke Kamen Rider leaps forward and blocks the laser beam fired by Ark with his sword, and the light collides with the light, creating a dazzling firelight. He landed on the gravel in the air, his eyes as sharp as an eagle, and he stared intently at Kamen Rider Ark.

Ark didn't stop attacking, its one-eyed glow fiery and quickly calculating its next move. Suddenly, Ark's metal arm quickly deformed, turning into a curved blade that slashed at the Kamen Rider Duke like a chainsaw.

The Duke flicked his sword away from Ark's blade, but Ark didn't stop, and the metal arm deformed again, turning into a giant hammer and slamming into the Duke. The Duke dodged, but was still swept away by the aftermath of the hammer blow and fell into the rubble.

Ark quickly caught up, and his metal arm returned to its normal form, which it used to perform deadly attacks. The Duke stood, sword in hand, and resisted Ark's blow. The sword moves of the two are intertwined, and each swing brings the power of shaking the earth and the mountains. The sword moves of the two are intertwined, and each swing brings a powerful impact of power.

Ark's metal arm resembles a unicorn's horn, constantly shuttling through the air, forming a lightning-like attack. The Duke used his sword to block each of Ark's attacks, but his armor had already shown noticeable damage under Ark's blow, and shards flew and sparks flew everywhere.

The duke knew that he had to find an opportunity, otherwise the battle would be against him. He concentrated, waiting for Ark's next attack. At that moment, Ark's metal arm suddenly split into several slender tentacles, wrapping around the duke's sword like an electric python, binding it tightly.

The duke felt a powerful force coming to him, trying to snatch the sword from his hand. He struggled with all his strength, but the tentacles grew tighter and tighter, and he felt that his sword was about to be snatched away.

Ark's one-eyed scarlet flickered, as if mocking the Duke's struggles. Its computing power allows it to anticipate the Duke's every move, including rebellion. 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 let out a loud shout, and the blade of the sword burst out with a powerful light. The light was like lightning, shattering the tentacles in an instant, freeing his sword.

The battle between Kamen Rider Ark and Kamen Rider Duke reached a fever pitch. Both have shown great strength and tenacity to fight.

To that end, they decided to unleash their special moves to bring the battle to an end.

"Kamen Rider Ark... Ark's metal arm quickly parted, turning into tentacles that glowed red. It stretched these tentacles into the sky and began to spin, forming a huge vortex. The red ball of light in the center of the vortex shone with a blazing light.

Ark raised his hands high above his head, palms facing up, extending his tentacles, leaning slightly, ready to release a huge amount of energy. The posture is like a mechanical god of war with a red halo.

"Crimson Vortex!" Ark's voice rang out in a unique mechanical sound effect, and the ball of light erupted with fiery red energy, creating a powerful gravitational field. The rubble and wreckage in the ruins were sucked into the whirlpool, forming a huge whirlwind, as if a meteor was piercing the night sky. The swirl of red flames swept like flames, slamming towards the Kamen Rider Duke.

"Kamen Rider Duke... At the same time, the armor on the Kamen Rider Duke emits a brilliant golden light. With his sword in both hands, he held the gilded sword high above his head and stood at the top of the ruins, staring at Ark.

"Royal Wrath!" The Duke's voice resounded throughout the arena, and the brilliant golden light of the sword blade merged with the splendor of the armor. He poses like an imperial king, standing at the top of a battle.

Ark's swirl of red flames and the Duke's royal wrath meet each other. Two powerful energies collided together, making a deafening explosion.

Ark's swirls were red and burning like fire. And the Duke's Imperial Wrath emitted a glittering golden light, as if it were a waterfall of gold.

The energy conflict between the two formed a chaotic spark in the air, and the energy fluctuations overflowed wantonly. The ruins of the city were even more devastated, and buildings were completely razed to the ground.

Both Ark and Duke are trying to unleash their special moves, and each other's powers are unleashed to the limit. The figures of the two loomed in the energy fluctuations, like a duel between the god of war and the emperor.

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

......

The battle is over.

Looking at John Walker, who came out with a sweaty face, Nathan Hawk smiled and applauded: "Thank you for your hard work, great fight."

John Walker saw that Nathan Hawk was waiting for him at the exit in person, his face was surprised, and he hurriedly said, "It's not hard, it's not hard." "

Haha, I said it, now John is very strong, his azure form, if Duke Azure is turned on, Ark will not be an opponent at all. Zhan Ji Ling Ma also walked over, raised his eyebrows and looked John Walker up and down, and then quipped, "It's a lot more handsome."

John Walker nodded a little bewildered, not knowing how to deal with the quips of the Warriors.

Seeing this scene, Nathan Hawk couldn't help laughing, if it was John Walker when he became Captain America in the future, then he must have smashed it with a shield, and he would not mature in the green road like he is now.

"Let's go to the infirmary and get some rest. Nathan Hawke patted the other person on the shoulder, and found that the heat on the other person's shoulder was surprisingly striking.

"Go ahead. Zhan Ji Ling Ma also said.

"Okay, then boss, doctor, I'll leave first. "John Walker was a little flustered when he left.

After John Walker left, Nathan Hawk raised an eyebrow and asked, "I just patted him on the shoulder, what did you inject into his body?"

"Boss, the power of Duke Azure comes from the blessing of the Azure Mystery, but this power is still unbearable for John. Although John's body was strengthened, it required greater physical endurance to fully control this power.

Nathan Hawke nodded, motioning to continue.

"So, I made some adjustments and injected the medical data we collected in the 2077 world, and the synthesis formula in it, combined with our original Human Gene Virus Excellent Liquid, strengthened his physical fitness and made him more adaptable to the power of Duke Azure. But that wasn't enough, I also added the Desperation Virus to it, which was to stimulate his potential, the potential when his body was torn apart, so that he could unleash more power in a critical situation.

Nathan Hawke frowned slightly, "You're playing with fire like this." "Playing with fire in every sense.

"Are you sure it's okay to do that?" asked Nathan Hawke, worried about the unintended consequences of this decision.

Zhan Ji Ling Ma nodded and replied, "I have made some modifications to the Desperate Virus, creating a balance between it and other viruses that will not cause too many problems. And, I'm constantly monitoring John's situation 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 drop the chain at a critical time, I will fully support it."

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 Ling Ma of that man.

Wu Dao Guihu recalls the days when the two worked together.

Look at the figure of Nathan Hawke leaving.

Sengoku turned his head to look at the marks formed by Kamen Rider Ark's battle with Kamen Rider Duke.

muttered: "Guihu, he is also a rare good boss." "
