This must be the . Lu Zhen's eyes turned golden as he observed the liquid.

"Just as I expected, it was indeed the Harmony Sapping Scarlet Essence."

"I was correct to catch this guy off guard..." Lu Zhen gazed at the armour as if he could sense the despair and reluctance to die within it.

As Lu Zhen was entirely invisible to the mage's radar and moved swiftly, he didn't provide the red-haired mage any chance to prepare, catching him off guard. This was why he was able to defeat the mage so easily.

Even the mage's butler had posed a significant challenge to Lu Zhen, nearly killing him. If he had been indecisive or given the red-haired mage enough time, he would be dead without a doubt.

Lu Zhen had no doubts about that. The conversation that had occurred before he broke through the barrier earlier might have been nothing more than a ploy by the mage to buy time, allowing him to prepare. It was all empty talk, after all.

Words have absolutely no value!

No matter what you say, as long as something doesn't bind you, it's empty talk at most. That doesn't mean words can't be taken advantage of. They can be used to stall for time, as the mage did, or to make an impression on people.

The first thing someone notices is your appearance, but the second thing they judge is your voice. So, although words may not have intrinsic value, they are still useful for many things.

Although Lu Zhen had a certain bottom line, he didn't care much about what he said as long as he accomplished his task. This approach was rooted in his experiences from the slums of his previous world, the lowest point in his life.

However, Lu Zhen didn't focus much on the tube with the red liquid. Instead, he turned his attention to the left, where there were two cages.

"It's a pleasure seeing you again, Ju Ji, right? You can stop pretending to be asleep; I know you're not," Lu Zhen's cold voice resonated as the white-haired girl's body trembled, and she let out a resigned sigh.

"What do you want?" She opened her eyes and turned, meeting Lu Zhen's crimson eyes with her abyss-like black ones.

"I want to know about this," Lu Zhen pointed at the red liquid in the glass tube to his right.

Ju Ji frowned visibly when she saw Lu Zhen pointing at the red liquid, but soon her expression shifted into a smirk.

"I don't know."

"I'm not talking to you; I'm talking to your master," Lu Zhen said with an amused smile as he looked at her. "You have some form of connection with her, right? Tell her that I have a proposal for her."

Ju Ji's eyes widened when she heard this and regarded Lu Zhen in a new light.

"How did you know?"

"You don't need to know. Just contact her first," Lu Zhen said, his stare icy and threatening. It was as if he would kill her at any moment if she didn't comply.

Suddenly, Ju Ji's abyss-like eyes transformed into white, ghostly eyes, and her demeanour underwent a complete shift as her aura surged to a terrifying level.

"Oh, it's like a possession, similar to what happened with Xia Mei before," Lu Zhen observed carefully, noting the changes occurring. He imprinted these observations in his memory, as it was a valuable opportunity for him.

He hadn't forgotten the dramatic transformation Xia Mei underwent when they first made a connection. It had been enough to make his heart race with just a glance. From the demeanour of the Ancestor, Lu Zhen had a feeling that Ju Ji's master might not be as formidable as Xia Mei's Ancestor.

"So, what do you want?" Ju Ji's white eyes were now focused on Lu Zhen, an amused expression on her face.

"Cut to the point. I know you already know what my condition is now. Tell me the solution," Lu Zhen's eyes turned cold as he stared at her.

"Weren't you the one who broke our deal previously? What if I don't help you?" Ju Ji questioned.

"If you don't help me, I will kill this girl," Lu Zhen looked at the girl who didn't even flinch, then continued, "You will make an eternal enemy out of me. I will chase you to the ends of the earth to kill you."

Ju Ji was taken aback slightly, looking at Lu Zhen with more consideration.

"You will die. Why should I care about revenge from a dead soul?"

"Are you sure?" Lu Zhen asked her with a confident smirk.

"Don't forget, I have the ancient warrior physique," Lu Zhen remarked.

"That won't help you for long..."

"So, you won't help me?"

"No."

"Okay," Lu Zhen nodded in understanding as he walked away, dragging the corpse with him.

"Wait, are you just walking away? Don't you want to live?" the girl exclaimed loudly as she saw that Lu Zhen didn't seem to care about her.

"I can just find the solution here," Lu Zhen responded without looking back as he searched the bookshelves one by one.

He looked at the complex titles which eventually decided to pick a book at random, and began to read it.

"Do you even know any mage languages?" the girl asked, her voice quivering, as she watched Lu Zhen reading the book.

"Yes," Lu Zhen replied simply, without looking away from the book.

"I can tell you the cure as long as you become my servant."

"Who would accept your offer?" Lu Zhen replied with an expressionless face.

"What the hell is this language?" While Lu Zhen's brain could comprehend the words, he couldn't make sense of the content. It appeared far more complex than even advanced mathematics like calculus in his previous world.

The content was more about science and the laws of physics, which were entirely different from his previous world and far too vast for Lu Zhen to comprehend fully.
