Hearing Xue Keyue's words, You Xin hesitated for a moment before nodding.
He understood clearly that Song Pinxuan's grandfather was no longer alive, so he could exert some pressure without repercussions from the Song family. However, Xue Keyue's grandfather was still alive, and directly crossing him was out of the question. He had to gauge the appropriate level of interaction.
Yet, as he watched Xue Keyue walk away to make a phone call, You Xin sneered inwardly:
"Hmph! Our old man has taken the longevity serum and can live for a long time. Your old man, on the other hand, is already older than ours and without the longevity serum, he'll be dead soon."
"Moreover, I am the Deputy Commander-in-Chief, holding the military power. When all those old folks from your family are gone, and only our old man remains, I won't have to worry about you anymore!"
Song Pinxuan's various developed technologies had already been shared with regions across the country, including quantum communication technology.
Longcheng was also capable of producing quantum communication phones.
However, it lacked the "Apocalypse Mall," and being the capital, it had a much larger population, making supplies tighter than in Jiangcheng. Consequently, the variety of things that could be manufactured was less than in Jiangcheng.
Even so, individuals of Xue Grandpa's status would naturally possess a quantum communication phone.
Xue Keyue quickly dialed her grandfather's number.
"Yue'er, I've received everything you sent back. You just need to take care of yourself in Jiangcheng; don't spend points to buy things and send them back," came Xue Grandpa's robust voice as soon as the call connected.
However, Xue Keyue seemed to disregard his words, focusing instead on explaining her situation and recounting everything You Xin had told her.
This included Governor Han's assassination, You Xin's reassignment to Jiangcheng, Commander-in-Chief Yao entrusting the investigation of Governor Han's assassination to You Xin, You Xin's decision to investigate with Song Pinxuan based on the attackers' words, and her own impending restriction from contacting the outside world.
Xue Grandpa, having weathered decades of storms, understood the situation immediately upon hearing this.
Finally, Xue Keyue said, "Grandpa, among the things I sent you this time, there's a serum. I specifically got it for you; it can prolong life. Remember to use it."
After hanging up, Xue Keyue handed the phone to You Xin.
Hearing her last sentence, You Xin felt a surge of disdain:
"You people will never get to use a longevity serum that can truly prolong life. What you call prolonging life is merely psychological comfort."
Meanwhile, Xue Grandpa, after hanging up, looked at a bottle of serum on his desk.
He picked it up, shook his head, and chuckled wryly, "Is this the longevity serum?"
"Old You, is this why you betrayed the ideals of our youth?"
This was precisely the longevity serum obtained by Tang Li from the biological research institute in City D, and it was the rare cellular reversal longevity serum.
Although Tang Li had only obtained three vials, they could be replicated infinitely.
Having acquired such valuable items, Tang Li naturally wouldn't hoard them.
She planned to sell these two types of longevity serums in the "Apocalypse Mall" once the seismic activity stabilized.
For her, replicating the longevity serum only consumed spatial energy.
Although replicating the longevity serum consumed a significant amount of energy, with an energy density second only to delta particles, as long as she priced it high enough, she wouldn't lose out.
After all, this was something that could extend life. While not everyone could afford it, those who could would undoubtedly want it, so setting a high price was acceptable.
Before selling them to the public, Tang Li had already ensured that all her trusted subordinates had used one.
Before administration, she had also had some loyal subordinates test it, and only after confirming its safety did she and others use it.
This included Tang Guo, Peng Yixuan, Lu Wan, as well as Peng Yue, Zhong Heng, Bai Xunyang, Lin Xi, and also Song Pinxuan and Xue Keyue, all of whom had previously used this cellular reversal longevity serum.
Tang Li had gone to such lengths to obtain the longevity serum with the intention of winning over high-ranking officials who had been bribed by the R-country.
Xue Keyue's grandfather was the first such official she had courted.
Although he hadn't been bribed with longevity serum by the R-country, his connection to Tang Li through Song Pinxuan and Xue Keyue made him the highest-ranking official closest to Tang Li.
Naturally, if she intended to win him over, she would gift him this excellent item first.
Holding the longevity serum, Xue Grandpa then used the quantum communication phone to make another call.
The call was answered quickly.
"Tang girl, I've received the longevity serum you had Yue'er send me..."
