I'm in the Dragon Clan, bound to the Naruto Counterattack System

After parting ways with Caesar, Cheng Sui did not return to his dormitory to rest as he had said, but went straight to the Lionheart Society's headquarters.

Inside the quaint building, Susie was sitting in the hall. She looked slightly surprised to see Cheng Sui: "Senior Cheng Sui? Are you here to see the president? I'll go and inform him."

"No need, I've arrived." Chu Zihang's voice came from behind. He had appeared quietly without anyone noticing, and looked calmly at Cheng Sui. "I thought you would be delayed by Caesar for longer."

Cheng Sui grinned, casually putting his arm around Chu Zihang's shoulder, and with his other hand pulled out the keys to a Bugatti Veyron, twirling them deftly between his fingers: "Caesar even gave me a supercar to try and get closer to me. Senior Brother Chu, what kind of gift are you planning to prepare for me?"

Although he didn't understand why Cheng Sui still called him "senior brother" in his senior year, Chu Zihang thought seriously for a moment and said in a calm but solemn tone, "If you need it, I can give you Murasame."

Cheng Sui clearly saw a struggle flash in the boy's eyes, which he then suppressed. Murasame was obviously of great significance to him, but he was willing to give up Murasame for the sake of Bloodlust.

Is that all it takes to become stronger without considering the consequences? Even at the cost of everything?

What a stubborn brat.

Cheng Sui curled his lip: "It's just a knife, what would I do with it? Never mind, let's talk about that bloodline refining technique you mentioned in your email."

"Let's talk as we walk," Chu Zihang turned and led the way. "There are some things you need to see to understand."

Cheng followed in his footsteps.

Following the wooden escalator, Cheng Sui and Chu Zihang arrived at the old archives of the Lionheart Society, where important manuscripts and files of Lionheart Society members from all generations are stored, and the air is filled with the special smell of old paper and ink.

"By the way, why did you choose me to help you research this?" Cheng Sui asked casually, his hands behind his head. "Wouldn't Caesar be a better choice? He has a large family business and plenty of resources."

"Because I can't understand your transformation." Chu Zihang stood in front of a row of old bookshelves, his gaze sweeping over the spines of the books. "You were a C-level from freshman to junior year, but in your senior year you seemed to have undergone a complete transformation, and even your bloodline rating was changed to A-level. I want to know why."

Cheng Sui really wanted to say, "Actually, my bloodline is still C-grade. My sudden increase in strength has nothing to do with my bloodline."

Thinking of this, Cheng Sui suddenly came to his senses. Why did Angers and the Night's Watch not have any doubts about his increased strength? In fact, the Night's Watch's suspicions were inexplicably dispelled.

What he didn't know was that the Night Watchers had already come up with a self-consistent explanation, academically demonstrating the possibility of Cheng Sui's sudden increase in strength.

"You suspect that I used some kind of bloodline refinement method?" Cheng Sui asked tentatively.

Chu Zihang nodded, tacitly agreeing.

Cheng Sui said helplessly, "Then I regret to inform you that my becoming stronger has nothing to do with bloodline refinement. If you want to gain any experience from me, you'll probably just be wasting your time."

"It's alright. Even if you don't understand, you yourself are a valuable research subject."

Sample? Senior Brother Chu, can you please not speak so frighteningly...?

Chu Zihang took two items from deep within the bookshelf: an old notebook with a suede cover and a piece of parchment paper, only half intact with charred edges.

Cheng Suixian picked up the notebook and began to look through it, his brows furrowing deeper and deeper. At first, he thought it was some kind of strange handwriting, but after flipping through several pages, he was certain that it was not any known script at all; it was twisted and coiled like a ghost's scribbles.

"What is this? Is it an alien manuscript?" Cheng Sui pushed the notebook towards Chu Zihang.

"Do you know about Leonardo da Vinci's manuscripts?" Chu Zihang asked.

"That notebook that sold for an astronomical price? I've heard of it."

"That's just one of them. He also has an undeciphered manuscript that uses a similar anonymous script." Chu Zihang said, taking out two mirrors from under the table and placing them at a specific angle. "Later, a collector tried to decipher it using the mirror reflections and discovered the secret: Leonardo da Vinci wrote in reverse with his left hand while looking at his reflection in the mirror. I borrowed this method."

He unfolded the suede notebook in front of the mirror. Cheng Sui looked at the mirror, and the previously illegible text had suddenly transformed into smooth and beautiful English cursive.

"How did you find this?" Cheng Sui asked curiously.

"Keep trying," Chu Zihang replied simply.

Those four simple words made Cheng Sui feel as if he were seeing countless nights, this silent and stubborn boy alone, buried in the dim archives, trying different methods again and again, just to dig out a sliver of hope for becoming stronger from the piles of old papers, just so that one day he could wield a sword against the gods.

Cheng Sui opened his mouth, but remained silent for a moment.

Chu Zihang picked up the half-burnt parchment: "This was found in the lining of an old book. It records a secret technique called 'The Path to Godhood,' which can temporarily refine the bloodline of the dragon race. Unfortunately, the key parts are missing."

Cheng Sui pointed to the suede notebook and asked, "And what's this?"

"The notes of Menek Cassel, the founder of the Lionheart Society, contain fragmented records of the early members' research into the 'Path to Godhood,' but the process abruptly ends at crucial points. Perhaps they considered the technology too dangerous and used a more covert method to preserve the core content."

"So, what progress have you made so far?" Cheng asked.

Chu Zihang shook his head: "I've only deduced that the principle is roughly to temporarily suppress human will, allowing the dragon genes to achieve an overwhelming advantage. But the specific implementation method... I still don't know."

"So, what is the price?"

Across the table, Cheng Sui gazed into Chu Zihang's dark, pure eyes, which seemed to contain the entire night sky. These eyes might soon ignite with an inextinguishable golden light.

"Each time the bloodline is refined, it will permanently increase the basic level of the purity of the dragon blood in the body, until it becomes a Deadpool." Chu Zihang's voice was calm, as if he were talking about something insignificant.

"Is it worth it?" Despite knowing Chu Zihang's past and his obsession, Cheng Sui couldn't help but ask. Even though he already knew the answer.

Even if we could do it a hundred times over, this brat would still choose this path of no return.

Chu Zihang did not answer, but the determination burning in his eyes said it all.

Cheng Sui suddenly brought up a seemingly unrelated topic, "Chu Zihang, do you think it's possible for the Dragon King and a human to be together?"

"No," Chu Zihang said decisively without the slightest hesitation.

"No, no, no," Cheng Sui held up a finger and shook it, "This time in Egypt, I personally witnessed the love between the former Dragon King Ramses II and his human queen. Remember this, it's possible for a Dragon King to fall in love with a human."

Under Chu Zihang's slightly bewildered gaze, Cheng Sui stood up.

"Your body is a reservoir, dragon blood is the water, and the dam determines the water level. What we need to do is not to pour water in, but to controllably and gradually lower the height of the dam. Do you understand?" Cheng Sui pointed out the most crucial core idea based on his memories from his previous life.

Chu Zihang's mind suddenly cleared up, as if some shackles had been broken and countless confusions were instantly resolved. When he looked up again, he found that Cheng Sui had already left at some point.

But... why did Cheng Sui suddenly bring up the story of the Dragon King and the human falling in love?

Chu Zihang fell into deep thought.
