Lu Zhen looked at the book with an expressionless face while using his five senses to carefully observe the girl.
The white-haired girl stared at Lu Zhen with a frown.
Time passed as Lu Zhen tried to understand the book, and the girl simply watched him.
Finally, after a long time, she opened her mouth, her eyes filled with disbelief.
"How can you be alive even after getting infected by it? Even with the ancient martial physique, there is no way you can reach that realm so easily," the girl stated, her disbelief evident in her eyes.
Lu Zhen finally put down the book with an expressionless face and started to select another book. However, unlike before, he carefully examined all the books with his golden eyes. When his eyes lit up, he thought to himself, "Finally, I've got one."
"I should have done this previously as well," he thought, his expression turning bitter as he took the book in his hands. Upon seeing this book, the white-haired girl's eyes widened.
"Does he really know our language?" she thought to herself, feeling somewhat uncertain. However, it was quite possible, as the mage language was nothing special. It had been lost in time after the destruction of the mages, but some of it might have survived to this day.
Her fist tightened as she considered this. With determination, she looked at Lu Zhen and thought, "I need his help very badly right now."
Lu Zhen paid no attention to the girl's stare as he focused on the book.
The front page of the book displayed a title in bold letters: "Encyclopedia of the Curse Elixir."
"So, these infected-like things must be a curse elixir?" Lu Zhen wondered curiously. He opened the book and examined the front page, which resembled a table of contents with the names of various elixirs and brief descriptions of their effects.
"How neatly organised," Lu Zhen mused to himself, unable to suppress his wonder about the level of advancement during the mage era, which appeared to surpass his previous world.
He found a word that excited him even more: "Harmony Sapping Scarlet Essence." His eyes lit up as he quickly turned to the page, carefully reading every word.
"What do you want in return?" Lu Zhen asked, trying to understand her terms.
"I want your assistance in obtaining a suitable body for my possession," she explained.
Lu Zhen raised an eyebrow. "Can't you find one yourself?"
"No," she replied. "I need a living, first-stage martial artist body to revive myself."
"Hmm, why me then?" Lu Zhen inquired, genuinely curious about the girl's choice.
"Because you possess the ancient martial physique," she explained. "My best chance of reviving myself is to rely on you." Her expression conveyed that this was the most logical choice.
"You really overestimate me," Lu Zhen chuckled.
"Looking at you, you must be very close to a second-stage martial artist, so..." the girl said with shining eyes.
"Okay, I agree," he said after a moment of thought.
The girl reached out, and a paper appeared out of thin air in her hands. She handed it to Lu Zhen, who tentatively approached the cage and accepted the paper.
"Hmm," Lu Zhen murmured as he examined the contract carefully. The first page bore bold letters and simple words: Blood Contract.
"Eh a contract..."
"Do you think words will give any validation?" she sneered.
Lu Zhen continued flipping through the pages of the contract. The language was unknown to him, but strangely, he comprehended the essence of the document even without using his Appraisal skill.
