Jiang Qinyu understood; so he had come to see Lu Yanzheng. "Unfortunately, my general has already gone to Qinzhou with Young Master Xiao today."
"What?" Lu Qingsheng exclaimed in surprise, "They went to Qinzhou?"
Upon hearing this, Lu Wanqing became anxious, "Father, we must have missed our cousin and the others!"
Her father was the military commander of Yukang Prefecture, and he would definitely be notified of any military mobilization. The fact that her father was unaware of it meant that the event was sudden and they missed the opportunity to receive the news.
At this moment, Lu Qingsheng no longer cared whether Lu Yanzheng looked like his deceased wife. He stood up and bid farewell to Jiang Qinyu, saying, "Madam, I came in a hurry today and have only prepared a small gift. I have urgent business to attend to and must leave now. I will visit you another day."
Jiang Qinyu curtsied, "Lord Lu, official duties are of utmost importance."
Lu Wanqing also apologized to Jiang Qinyu, saying, "I hope you won't take offense at my disturbance today."
Jiang Qinyu shook her head, "Miss Lu is welcome to come anytime. There's no need for such formalities."
The Lu family father and daughter arrived quickly and left just as quickly. Jiang Qinyu didn't understand why they came to see Lu Yanzheng, but thinking about it, the two sides didn't seem to have much interaction, so it shouldn't be anything serious.
She quickly put the matter out of her mind and continued to devote herself to the development of the smallpox vaccine.
The post I made yesterday has already received many replies today.
Overall, syringe production lines are available for purchase, and there are even people leaving messages offering to sell complete syringe and infusion bottle material production lines.
Jiang Qinyu couldn't help but marvel at how powerful the system was, managing to bring together people from so many different dimensions.
Oh, and by the way, the system only selects one host in each dimension, and only randomly selects the next successor after the host dies.
Based on Jiang Qinyu's observations while lurking on the forum, there has never been a case where two hosts were blood relatives. In other words, after her death, there is basically no possibility that her system will be passed on to her descendants.
Let's get back to the main topic.
Besides the proper modern production line, there are also many refining products from the cultivation world. However, these renewable magical artifacts are very expensive, and Jiang Qinyu can't afford them with the few points she has.
After much deliberation, Jiang Qinyu chose only one production line that simply produced hollow syringes, spending 50,000 points.
Although Xiao Rui said he had a remarkable person on his side, and that he could send someone to develop it, it was uncertain when the finished product would be available. It would be better to use the existing one for now!
Most importantly, Lu Yanzheng has begun to waver. If he stops assisting Xiao Rui in the future, then the technical support provided by Xiao Rui will be gone. Therefore, it is better to keep the technical aspects in one's own hands.
As for where she came from... well, with Lu Yanzheng blocking her way, she can just obediently be a good wife.
Two days later, Jiang Qinyu took the samples that came with the production line she bought to Doctor Mo.
"Old Mo, the general recently encountered a remarkable person who made the syringes we need. Could you please take a look and see if it works?"
Jiang Qinyu handed him the syringe.
Doctor Mo examined the syringe closely and exclaimed excitedly, "Truly a remarkable person! This is exactly the kind of syringe I've always dreamed of—one that can deliver medicine directly into the body!"
"Where is this extraordinary person? Has the general brought him back?" Doctor Mo asked excitedly.
Jiang Qinyu shook her head and said regretfully, "That senior has long since stopped caring about worldly affairs, and his whereabouts are unpredictable. He only made these few syringes and sent them over. Even I don't know where he lives."
"Is that so?" Doctor Mo lowered his eyes in disappointment, but he quickly cheered up again. "It's alright. As long as we have this, we can find someone to make it."
Jiang Qinyu suddenly smiled playfully and said, "Old Mo, there's no need to go to such lengths. Although that senior won't make it for us personally, he has passed on his experience in making these syringes to me. We just need to gather the materials and find the old blacksmith to make it."
She also bought the production line blueprints. With samples and blueprints, plus her knowledge of crucible steelmaking, what couldn't she make?
"That's wonderful!" Doctor Mo was overjoyed. "My prescription has been finalized, and I can start decocting the medicine tomorrow. Madam must come and take a look."
"Alright, with Elder Mo's help, we're sure to succeed," Jiang Qinyu said with a confident smile.
Doctor Mo was a little embarrassed by what she said, and waved his hand, saying, "It's not that mysterious. Let's take a look at the medicine tomorrow."
Since it's a drug that's to be injected directly into the bloodstream, it can't be at the same concentration as oral medication. If the concentration is lower, the efficacy can't be reduced. He bluntly said that there are very few people in the world who can make such a drug.
Jiang Qinyu was also quite curious at this moment. How different was the medicine developed by Doctor Mo from the transparent vaccines of modern times? And what were its effects?
When she got back, she asked A-Ping, "Did you find the white mouse?"
"Madam, we haven't found many of the white mice you requested, but we have found quite a few gray ones. What do you think..." A-Ping said, somewhat embarrassed.
He rarely saw white mice, and in the past few days he had asked people to search everywhere but hadn't found many. But his wife wanted to find more, the more the better.
Jiang Qinyu said, both amused and exasperated, "The color of the mouse doesn't matter, as long as it's a newborn one."
"White mouse" is just a euphemism; it's her fault for not making it clear from the beginning.
To conduct a more comprehensive experiment on the drug's efficacy, we need to prepare a larger number of mice and a complete control group to better observe the effects.
Thinking of this, Jiang Qinyu suddenly remembered that she hadn't explained this to Elder Mo in detail yet. She should write down the important points first so that she could monitor the changes in the drug's effects with Elder Mo later.
While Jiang Qinyu and Doctor Mo were busy developing a smallpox vaccine, Lu Yanzheng and Xiao Rui were fighting a bloody battle against a group of people who had ambushed them.
"Protect His Highness!" Eleven, clutching his injured arm, stood in front of Xiao Rui.
Xiao Rui stared intently at the two sides locked in fierce combat.
They were ambushed before they even reached Qinzhou. If it weren't for Lu Yanzheng, he would probably be dead by now.
The newcomer must have known them well, as they immediately sprayed poison. Eleven and the other guards were all affected to some extent and quickly found themselves at a disadvantage in the battle.
Only Lu Yanzheng, whose constitution was unknown, or perhaps whose martial arts skills had reached a certain level, seemed to be immune to these poisons.
At this moment, Lu Yanzheng remained calm as he swiftly reaped the lives of his enemies.
"General Lu! Our prince is willing to recruit you with the utmost sincerity. You should make sure you're sure before you act!"
The men in black finally couldn't hold on any longer and retreated while fighting. Suddenly, the leader gritted his teeth and shouted.
"Prince Yong?" Lu Yanzheng suddenly realized who the other party was.
