Summon the Villain: Marvel.

Under Shennong's fierce attack, Nathan Hawke calmly analyzed the difference between this air ninja leader and Luo Sha, whom he had faced before. The two had completely different fighting styles and abilities, which required him to adjust his strategy when dealing with them.

First of all, Shennong's physical skills are extremely fierce and varied. Every punch and kick of his is full of power and speed, and his offensive is coherent and without pause. Compared with Luo Sha, Shennong pays more attention to close combat, using the medical forbidden technique of flesh activation to enhance his body's ability, allowing him to burst out with extremely strong combat power in a short period of time.

"Luo Sha's attack relies more on the control of gold dust. His long-range attack and defense capabilities are very strong, but he is relatively weak in close combat." Nathan Hawke thought silently in his heart, "But Shen Nong is different. His close combat ability is very strong. His body activation and regeneration ability makes him almost free from fatigue and injury in battle."

Nathan Hawke was thinking while defending, and he clearly realized that Shennong's strength was not only in his physical skills, but also in the forbidden medical skills that could quickly restore and strengthen the body. This forbidden skill made Shennong's combat power almost unlimited, and as the battle continued, his attacks would only become stronger and stronger.

"Although Luo Sha's magnetic ninjutsu gold sand is powerful, it relies on the consumption of chakra after all. Once the chakra is exhausted, the combat effectiveness will be greatly reduced." Nathan Hawke continued to analyze, "In comparison, Shen Nong's recovery and regeneration ability gives him an advantage in a protracted battle."

Shennong's fist attacked again, bringing with it a strong wind pressure. Nathan Hawke quickly dodged sideways, then counterattacked with a punch that hit Shennong's abdomen. Shennong reacted quickly, raising his hand to block Nathan Hawke's attack, and the fists of both sides collided again, making a dull sound.

"Moreover, Shennong's fighting style is more direct and fierce." Nathan Hawke commented secretly, "He won't give his opponent any chance to breathe. Every attack is full of destructive power and oppression."

As the battle continued, Nathan Hawke gradually figured out Shennong's fighting rhythm and weaknesses. He knew that if he wanted to defeat Shennong, he had to find his flaws in close combat and use his attack loopholes to counterattack. At the same time, he had to be wary of Shennong's recovery and regeneration abilities and not give him the opportunity to use forbidden medical techniques to recover his physical strength.

"It seems that this battle will be a protracted one." Nathan Hawke thought calmly, with a gleam of determination in his eyes, "But I won't let him have any chance to breathe. I have to play out his trump card of fusion with Zero Tail."

Nathan Hawke's eyes became sharper. His body was instantly wrapped in electrical energy, and blue arcs flashed around him, stimulating his nerves and muscles, bringing his reaction speed and strength to a new level. He closed his eyes and concentrated his mind, and telekinesis quickly flowed through his body, enhancing his physical fitness. Telekinesis can not only be used to manipulate objects, but also make his movements more precise and rapid by finely controlling every cell in the body.

Shennong attacked again, his fist with strong wind pressure, hitting Nathan Hawke's face directly. Nathan Hawke's eyes were calm, his body instantly disappeared from the spot, appeared on the side of Shennong, and a high-speed side kick hit Shennong's waist directly.

Shen Nong was kicked away by this blow and hit the wall heavily. He stood up quickly, his eyes full of surprise and anger: "You can actually dodge my attack?"

Nathan Hawke did not answer. His body disappeared again and instantly appeared in front of Shennong. With his fists shining with electric energy, he suddenly attacked Shennong. Shennong quickly formed a seal and activated his body to try to resist Nathan Hawke's attack. However, Nathan Hawke was too fast and Shennong's defense could not keep up with his attack rhythm.

"You can't see my movements anymore." Nathan Hawke said coldly. His fists fell on Shennong's body like raindrops. Each blow carried a strong electric energy shock, causing Shennong's body to tremble constantly.

Shennong gritted his teeth and tried to fight back, but Nathan Hawke's speed and strength completely suppressed him. Every attack of Shennong was cleverly rebounded by Nathan Hawke, causing Shennong to gradually lose the upper hand in the battle.

"Your physical skills are very strong, but they are so powerless in front of my speed and strength." Nathan Hawke said coldly, his fist shining with electric energy, and suddenly hit Shennong's chest.

Shen Nong was knocked back by this blow, blood oozing from the corner of his mouth. A trace of anger and unwillingness flashed in his eyes, but he understood that Nathan Hawke's strength had completely surpassed his own.

Nathan Hawke did not give Shennong any chance to breathe. His body disappeared in an instant and appeared behind Shennong again. He grabbed Shennong's shoulders with both hands and his telekinesis burst out instantly, throwing Shennong to the ground.

Shennong fell to the ground, blood oozing from the corner of his mouth, but his eyes still flashed with madness and fighting spirit. He slowly stood up and quickly formed a seal: "Zero Tail Ritual, activate!"

Suddenly, the air in the underground space became oppressive and cold, and dark chakra began to gather in Shennong's body. His body swelled rapidly, his muscles became stronger, and his skin turned dark black, as if covered by the power of darkness. Shennong's eyes flashed red, and the whole person exuded an indescribable evil aura.

"Eight Gates of Ninjutsu, fully activated!" Shennong roared, and his body was instantly wrapped in strong chakra. The blue light and dark chakra intertwined together, bringing his power to a new height.

Nathan Hawke watched Shennong's changes calmly, his body leaning forward slightly, ready for battle.

"Physical Technique: Bone-Splitting Fist!" Shennong suddenly rushed towards Nathan Hawke, and his fist hit Nathan Hawke's chest with strong penetrating power and diffuse pain.

Nathan Hawke dodged quickly, his body instantly turned into a beam of light, disappeared from the spot, and appeared on the side of Shennong. Nathan Hawke's fingers moved lightly, and the power of the Shining Fruit burst out instantly, and a strong beam of light hit Shennong directly.

"Do you think you can defeat me like this?" Shen Nong sneered. His body was hit by the beam, but the dark chakra quickly repaired his wounds. His eyes were full of madness and fighting spirit, and he rushed towards Nathan Hawke again.

"Physical Technique: Active Punch!" Shennong condensed a dark chakra ball in his palm and released it at Nathan Hawke at close range. Nathan Hawke quickly retreated, but the explosive force of the chakra ball still shook his body, making him feel a strong impact.

Nathan Hawke's eyes flashed with calmness and determination. His body turned into a beam of light again, and he quickly went behind Shennong. His hands, with the light of glittering fruits, suddenly attacked Shennong's back.

Shennong turned around suddenly, and his fists, with strong dark chakra, collided with Nathan Hawke's fist of light. The two powerful forces collided in the air, erupting with huge energy fluctuations, shaking the entire underground space.

"Ninjutsu: Super Divine Fist!" Shennong roared, his body was instantly wrapped in dark chakra, and his fists condensed into a huge chakra ball, which suddenly attacked Nathan Hawke.

Nathan Hawke calmly met the attack, his body transformed into a strong ray of light, and quickly dodged, while his hands condensed a beam of light from the Shining Fruit, hitting Shennong's chakra ball directly.

The two forces collided in the air, and a huge energy wave erupted. Nathan Hawke's light and Shennong's dark chakra intertwined to form a huge energy vortex.

As Nathan Hawke's eyes became sharper, Shennong decided not to hold back. He took a deep breath, and a hint of madness and coldness flashed in his eyes.

"Zero Tail Technique, Void Mode!"

Suddenly, the air in the entire underground space became even colder, and dark chakra quickly condensed in Shennong's body. His body began to undergo drastic changes, his muscles expanded rapidly, and his skin took on a deep dark black color. Shennong's eyes became like burning red flames, and a creepy evil light shone in his pupils.

Black smoke began to emerge from around Shennong's body, and the smoke swirled around him as if it had life, forming a huge dark vortex. Several snake-like dark chakra tentacles suddenly appeared behind him, twisting and coiling like snakes, emitting a terrifying aura.

"Now, you will see my true power!" Shennong's voice was low and threatening, his smile was ferocious and cold, as if he had foreseen Nathan Hawke's failure.

Shennong in Zero Tail Mode, his entire body was wrapped in dark chakra, emitting a powerful aura that could not be concealed. Every step he took left deep footprints on the ground, and the air around him seemed to tremble under his pressure.

"Prepare for your doomsday!" Shennong said coldly, his fists condensing strong dark chakra, ready to launch a fatal attack at any time.

On the other side, there was Kabuto who had been watching the battle.

Dou chose a relatively safe corner and stared closely at this extremely fierce battle. His face showed a complicated expression, his brows were slightly furrowed, and his eyes were flashing with excitement and nervousness.

"Shennong's power is so strong, this zero-tail mode is really shocking." Kabuto's heart was shaken, Shennong's strength made him feel a little uneasy, but more excited and curious. Orochimaru's plan can be implemented smoothly, this powerful enemy is the best test of Nathan Hawke's strength.

"Master Nathan Hawke's strength should not be underestimated. He seems to have been reserving his strength. What will be the outcome of this battle?" Kabuto was full of questions and expectations. He knew that no matter who won or lost, the outcome of this battle would determine the future situation.

Kabuto followed the two's movements closely, analyzing their fighting styles and strategies. He clenched his hands into fists, his heart filled with tension and anticipation: "Can Lord Nathan Hawke defeat Shen Nong? Or will Shen Nong's Zero Tail Mode completely defeat him?"

Dou swallowed involuntarily, his heartbeat quickened, and an excited look appeared on his face. He dared not take his eyes away from the center of the battle, for fear of missing any details: "No matter what the result is, this battle will be a rare learning opportunity. Being able to witness the duel between two top masters with my own eyes is too precious for me."

"Lord Nathan Hawke, how much hidden power does he have? How strong is his ability?" Kabuto's mind was working rapidly, trying to capture more information from the battle. His heart was filled with a desire for the unknown and awe of the strong.

Under the fierce impact of the battle, a trace of determination flashed in Dou's eyes: "No matter what, I must learn more from this battle and improve my strength." He took a deep breath and continued to watch the battle, his inner tension and excitement intertwined, waiting for the final result to be revealed.
