Slayer: Look directly at the Seraph, standing on the sun

"You think you can threaten me with these eyes?" Orochimaru's voice was calm as still water, but a sense of danger gradually spread from it. "Do you think I'll give in?"

“You will,” Zhang Hai said softly, his tone unwavering. “You need me, just as I need you. Only through cooperation can we break through existing limitations and reshape this world.”

Orochimaru's lips curled into a sneer again, a cold glint in his eyes. "You're right, we both need each other. Unfortunately, I don't believe anyone can change my fate." He extended his hand, gesturing towards Zhang Hai. "However, since you're so confident, let me see what you're really capable of."

Zhang Hai remained motionless, calmly watching Orochimaru. "You'd better think this through. Choosing to stand with me means you must pay a price. If you want power, you must accept its limitations. Can you bear that price?"

Orochimaru's eyes flashed with interest, then he nodded slightly. "Interesting. It seems this contest isn't just about power, but also about the choice between control and sacrifice." He held out his hand, signaling Zhang Hai to begin.

Zhang Hai smiled slightly, then took out a scroll from his sleeve. It was the agreement he had prepared for this cooperation—a seemingly ordinary document, yet filled with deadly traps. "Let's begin. Become my allies and help me achieve my goal of changing the world," he said calmly.

Orochimaru took the scroll, a sly glint in his eyes. "You really think I'd sign this contract so easily?"

"Whether you sign or not is your choice." Zhang Hai's eyes were devoid of any emotion. "But you should also be aware of the consequences of your refusal. Whatever decision you make, the outcome will be in your hands." His words were devoid of any emotion, like a cold blade cutting through the air.

Orochimaru chuckled softly, a calculating glint in his eyes: "Do you think I'm afraid? You're just a young ninja with powerful eyes. But you can never surpass me, because you don't have true power."

Zhang Hai's eyes suddenly sharpened. "Then you should give it a try."

As soon as he finished speaking, the Mangekyou Sharingan in his hand lit up, and in an instant, the surrounding space seemed to distort. The flow of time began to slow down, and even the dust in the air seemed to float slowly. Orochimaru frowned slightly; he keenly sensed that the surrounding time and space were changing, a change that seemed to exceed all his expectations.

"Is this your 'power of time'?" Orochimaru asked in a low voice, his eyes flashing with a complex light.

“This is just the beginning,” Zhang Hai replied coldly, his voice devoid of any emotion. “I am no longer the Zhang Hai who only thought of revenge. Now, I will change the whole world.”

Zhang Hai stood in Orochimaru's laboratory, the atmosphere heavy as if before a lurking storm. The laboratory was filled with the pungent smell of medicine and the metallic tang of old-fashioned machinery. Rows of bottles and jars, shimmering with a faint green light, hung on the walls, each containing the remains of various strange creatures. On the experimental table, a complex array of symbols hummed softly, a stark contrast to the surrounding deathly silence.

Orochimaru took a thick book from the bookshelf and casually flipped through it, a hint of calm interest in his eyes. When he looked up, Zhang Hai was already standing in front of him, his face calm and his eyes as unfathomable as a deep pool.

"Orochimaru, I need your help." Zhang Hai's voice was completely flat, as if he were stating a trivial fact.

Orochimaru stared at Zhang Hai's cold, piercing eyes, a mocking smile playing on his lips: "You young man, you dare to come to me? Do you think I'm the kind of person who would help someone so easily? Especially when you seem so desperate."

Zhang Hai remained unmoved by Orochimaru's provocation; his gaze remained firm and deep as the sea: "I know you've been searching for new power, new bloodline limits. I'll give you a chance. Use my blood to exchange for the plan you can help me complete."

Orochimaru's eyes flickered, clearly intrigued by the suggestion. He knew all too well that blood was a powerful and mysterious resource for ninjas, especially when it belonged to a ninja with a special bloodline limit; its value was immeasurable. Zhang Hai's eyes, the Mangekyou Sharingan, were something he had never seen before, and the "power of time" contained within them particularly captivated Orochimaru.

"Blood exchange?" Orochimaru repeated in a low voice, a greedy glint in his eyes. "Are you sure you won't lose too much by doing this? After all, it's already quite an achievement for someone like you to have survived this long."

“I know what you want,” Zhang Hai replied calmly, “but this is the only exchange I can give you. You want my eyes, you want the power of time, and only through cooperation can you get them. You and I both understand that if we don’t reach an agreement today, you won’t have another chance tomorrow.”

Orochimaru's smile gradually turned cunning. He looked Zhang Hai up and down, seemingly weighing every word he said. Finally, he said softly, "You see things very clearly, but are you prepared to pay the price? Blood for power sounds like a deal, but behind every deal lies an untold cost."

Zhang Hai smiled slightly, his eyes showing no sign of wavering. "The price is worth it. I don't care." His words were firm and resolute, filled with unwavering determination.

Orochimaru didn't seem to be in a hurry to respond. He pondered for a moment, then suddenly said, "Since that's the case, since you're already prepared, let's see if you can really shoulder all of this." His words carried a strange premonition, as if he were testing Zhang Hai.

Without hesitation, Zhang Hai reached out and slid a drop of blood from his fingertip into a small container. The bright red blood spread in the bottle, seemingly swallowing all the light around it. "This is my blood, and it's the only condition I can offer in exchange."

Orochimaru picked up the vial of blood, his eyes gleaming with greed and interest. "Alright, since that's the case, I agree. However, since you need my help, you must understand that the use of this power is not without its limitations. While 'Impure World Reincarnation' is powerful, it has a fatal weakness: it cannot fully control the mind and chakra of the sacrificed person. If you are prepared to accept this uncertainty, then we can begin."
