Weiss squinted at Allen, just when he found his expression that seemed to be smiling but not smiling, he couldn't help but curse in his heart, from what Old Jack said just now, Weiss had already heard something strange, and now he was going to explain. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

But I can't help but say it, Weiss thought about how to phrase it, and then said:

"Mr., in fact, this time I asked you to help, but there was a little problem, now that the matter has passed, we can talk about future cooperation, you can rest assured, this is also a partner." ”

Well, it came back to himself, Alan rolled his eyes, he didn't expect Vis to play such a move, so that he couldn't watch the joke on the side.

"In that case, now that I know what is on my mind, I should go back to Geer City and continue teaching my books. ”

Alan was a little anxious in his heart, not to say that this alchemist had to be Old Jack, but firstly, he really couldn't find any decent alchemist in a short period of time, and secondly, Old Jack was also a well-known alchemist back then, and he must be technically excellent, and he was definitely stronger than what he was looking for in a hurry.

It's not a difficult thing to keep Old Jack, as long as you move out of the Holy See, Old Jack will definitely stay, but that will inevitably give people a feeling of being threatened, and it will definitely not be so pleasant to cooperate in the future, so how to explain the situation is worth considering.

Alan pondered for a moment, then looked up at Old Jack.

"Old sir, in fact, this matter is far from over, and the real culprit behind the scenes has not been caught, so for the sake of safety, it is better not to return to Geer City. ”

"What, do you think they're going to take revenge on an old man like me?"

Even if they don't do this, it won't be possible for you to live an easy and happy life as the inventor of "dreams". ”

These words made Old Jack fall into deep thought, once these people knew the news that he was still alive, they would never let him go, whether it was to kill him or let Old Jack go to help with the research, it was not the scene that Old Jack wanted to see.

"And what do you need me for?"

At this time, Old Jack was still a little skeptical, didn't the Holy See want to continue to study the "dream" or use it for some purpose?

You know, these alchemists have always had no good impression of the gods, if it weren't for the fall of the gods that caused the current end of the situation, the current alchemy may not have a chance to appear at all, and the alchemy techniques mastered by the magicians are much more powerful than them, and it can really be called impossible to make it possible.

Therefore, alchemists are naturally a little averse to the church that represents theocracy, and once things are related to the church, they also habitually think about the dark side.

Old Jack is still an alchemist who has a little understanding of the Holy See because of the events of the past, and even he can't help but have this thought, and the image of the Holy See in the eyes of the majority of alchemists can be seen.

Alan smiled, he naturally saw the worries in Old Jack's heart, but these are not to worry at all, after all, Alan and Weiss are not interested in "dreams", and naturally they will not let Old Jack study this aspect.

"It's still related to the old gentleman's research back then. ”

Seeing Old Jack's face change slightly, Alan didn't wait for him to refuse, and continued: "But it's not the thing you think, let me ask first, did the mirror-making method you invented back then use tin and mercury?"

Old Jack was stunned for a moment, as if he didn't understand Allen's question, but since it had nothing to do with "dreams", Old Jack was not a person who liked to keep it private, so he nodded, indicating that it was indeed this method.

"This method is not only time-consuming and labor-intensive, but also the yield is not high. ”

Speaking of the old business, old Jack instantly came to his senses and put other things aside, "Yes, yes, yes, yes, I've always wanted to find a way to improve, but it hasn't worked, and then that happened......"

Old Jack's voice was low, but Alan was happy, he knew that these scientist-like characters had this problem, that is, they would have infinite nature and infinite regret for the experiments they had not completed, and Old Jack was obviously very sorry for this, as long as he grasped this, he would definitely let him stay.

"I have a good idea, but I still lack some ingredients, and I haven't been able to find time to finish it, so I asked the old gentleman to help. ”

"What! what a good way do you!"

Old Jack excitedly grabbed Allen's arms and got up from his seat, not realizing that his head hit the roof of the carriage with a dull thud.

Alan hurriedly helped old Jack to sit down, if something happened to this old gentleman, then everything would be stopped, and he and Weiss would honestly follow this ancient method of production and operation.

"Don't get excited, we'll talk slowly when we get to the place. ”

After a while, the carriage came to Vess's workshop outside the city, and Alan took Old Jack directly to a room in the workshop, which was a renovated alchemy laboratory, and it cost Vis a lot of gold coins for this small room.

Knowing that it was useless to stay here, Vis took his leave of the two of them and went to inspect his own territory, and Alan closed the door and sat down with Old Jack.

"Now let's talk. ”

Although Old Jack had calmed down a lot along the way, he was still a little excited at this time.

"Hehe, this method is also what I saw in an ancient book, because it is old, there are many places where the language is unknown, and we need to experiment slowly. ”

Hearing this, Old Jack frowned, "This, many ancient alchemy techniques require magic to be effective......

"Don't worry, I'm sure this doesn't require magic!"

Alan hurriedly reassured that it was just an ordinary experiment in high school, and it had absolutely nothing to do with magic.

Old Jack was silent after hearing this, in fact, he wanted to borrow this ancient book a little, but when he thought that this might be the internal collection of the Holy See, he dispelled this idea, not an internal member of the Holy See, and it was difficult to wait for the day if he wanted to borrow the collection of the Holy See.

Then, Alan told the silver mirror reaction about Old Jack, and with the help of Old Jack, Alan quickly figured out what these basic ingredients were called by these alchemists, no matter what they were called, anyway, in Allen's opinion, it was silver nitrate that was done, sodium hydroxide was no problem, and alcohol was not difficult.

Then there is only one remaining question, where to get ammonia, after asking Old Jack, Alan knew that there was no similar thing on the Holy Spirit Continent, that is, he could only find a way to make ammonia.

This is really fatal, who cares about how ammonia is made, anyway, Alan only has two ideas in his head, one is that lightning nitrogen fixation seems to have something to do with ammonia, and the other is to extract nitrogen from the air and then produce ammonia.

Either way, it's a bit unattainable.
