"Grandpa, I..."
Upon hearing Grandpa Long's words, Long Yuling immediately lowered her head, looking somewhat hesitant.
Lin Chen had already disguised himself when he boarded the plane in Zhejiang province.
Now, appearing here with Lin Xianfeng and Lin Yuelong, he must have his own plans.
"It's fine, there are no outsiders here. I'm an old man close to the grave."
"Yuling, although you are not my biological granddaughter, you know how I have treated you over the years."
"I can guarantee that no matter what secrets you have, as long as you tell me, I will absolutely not tell anyone else."
As he spoke, Grandpa Long turned to Long Yuling, his expression full of certainty.
The Qingxin Dan was a genuine fourth-grade elixir, and anyone capable of refining it was at least a fourth-grade alchemist.
What's more, the formula for the Qingxin Dan had been lost for a long time, and ordinary alchemists would never be able to produce it!
Yet here stood this young man, appearing to be only in his thirties, daring to boast before him that he could refine the Qingxin Dan.
Either he was mad, or he truly possessed the skill!
"This..."
Hearing Grandpa Long's words, Long Yuling looked conflicted and glanced at Lin Chen beside her.
Now that Lin Chen had disguised himself, if she were to rashly reveal his identity to Grandpa, wouldn't that put Lin Chen in a difficult position?
Without his consent, she would absolutely not tell Grandpa anything about Lin Chen.
"Old Grandpa, you don't need to be curious about my identity, but I can guarantee you that whatever Yuling wants me to do, if I can accomplish it, I will never refuse!"
Hearing Grandpa Long's curiosity about his identity, Lin Chen immediately spoke up to assure him.
He had no choice; these scions of prominent families were cunning, and this was his first time interacting with the Long family, so he didn't understand them at all.
Ultimately, he couldn't possibly reveal his true identity to Grandpa Long.
It could be said that among the entire Long family, the only one he truly trusted was Long Yuling beside him.
No matter what, she was already his woman, and this was something that could never be changed!
"Hehehe, alright. Since Mr. Chen says so, then this old man thanks you!"
Upon hearing Lin Chen's guarantee, Grandpa Long, though still a little curious, nodded in agreement.
While he hadn't received a direct answer, he had gotten what he wanted.
This person named Chen Lin must be using a false identity.
However, as the patriarch of the Long family and a seasoned elder, he could clearly see the adoration in Long Yuling's eyes when she looked at this Mr. Chen.
And the aura emanating from this Mr. Chen was subtle, undetectable even to him.
But when he looked at Long Yuling, his eyes held a hint of indulgence.
Clearly, their relationship was already quite evident.
"Thank you for your understanding, Old Grandpa."
Seeing that Grandpa Long didn't press further about his identity, Lin Chen expressed his gratitude.
Not long after, Long Feihu entered slowly, holding a brocade box.
"Dad, I've brought it."
After bringing the brocade box, Long Feihu immediately went to Grandpa Long's side, his expression respectful.
This brocade box contained one of the true treasures of the Long family, an alchemical furnace of the low-grade spirit artifact level.
It was unlikely that another one could be found in the entire cultivation world of the Long Kingdom.
But Long Feihu knew very well that if Grandpa Long's life couldn't be saved now, this alchemical furnace would eventually be snatched away by others.
The number of alchemists coveting this furnace outside was countless!
If it weren't for Long Yuling and Lin Xianfeng staking their lives as a guarantee, he would never have brought this item out.
"Hmm, Mr. Chen, forgive my bluntness, but this alchemical furnace is incredibly precious. When you refine the elixir, you absolutely cannot leave the Long family's premises."
"Whatever medicinal herbs you need, you can have Feihu prepare them for you, how about that?"
Upon seeing Long Feihu bring the furnace, Grandpa Long looked towards Lin Chen.
He had no choice; this furnace was too valuable. If Mr. Chen were to take it and run, then even if they killed everyone in the Lin family, they wouldn't be able to get such a furnace back!
Therefore, caution was paramount now.
"Alright, then please arrange a room for me, Old Grandpa."
"In ten days at most, I will be able to present the Qingxin Dan to you."
Hearing Grandpa Long's words, Lin Chen immediately gave his assurance.
For anyone else, refining such a fourth-grade elixir within ten days would be impossible.
But he was different. He possessed the Nine Dragon Ring, and the time flow within the Nine Dragon Ring's space was five times faster than the outside world.
This meant that ten days of seclusion in the Nine Dragon Ring would equate to fifty days in the outside world.
With fifty days, coupled with the assistance of this spirit artifact furnace, refining the Qingxin Dan would not be a difficult task.
"Oh? Ten days? So fast?"
Upon hearing Lin Chen's words, Grandpa Long was immediately astonished, his expression full of disbelief.
The Qingxin Dan was a fourth-grade elixir. As the patriarch of the Long family, he had witnessed others refine fourth-grade elixirs.
And those fourth-grade alchemists would typically spend months in seclusion when refining fourth-grade elixirs, which was commonplace.
But he never expected it to only take ten days?
"Hehehe, Old Grandpa, to be frank, if it were before, I might have needed two months."
"But now, with the furnace, ten days is a very conservative estimate."
Seeing Grandpa Long's disbelief, Lin Chen proactively offered his assurance.
"Moreover, Old Grandpa, considering your current physical condition, can you hold on for two months?"
Subsequently, Lin Chen couldn't help but show a slight smile.
It was precisely because he had noticed Grandpa Long's current physical state that Lin Chen was in such a hurry.
If it were too late, and Grandpa Long were to pass away, then even if he refined the Qingxin Dan, it would lose its original purpose!
"Alright, then I will entrust everything to Mr. Chen. If you need anything at all, please do not hesitate to ask."
After hearing Lin Chen's explanation, Grandpa Long couldn't help but laugh along.
Indeed, as this Mr. Chen had stated, given his current physical condition, being able to last for another month would be quite good.
Let alone waiting for two or three more months!
All they could do now was place all their hopes on this "Chen Lin"!
