The old man in the wheelchair listened to Richard's words, his eyes flashed, as if he was distinguishing the real from the fake, and after a while, he slowly put down the gun in his hand and said slowly: "Is that guy Sherlock...... Hmph, well, what help do you want from me?"

Richard didn't say anything long-winded, and said straight to the point: "Sherlock has a clock you made in his hand, the shell is a special silvery-white metal, I don't know if you have any impressions, I need some of this metal now, do some research." ”

"The silvery-white metal of the watch case?" Lawrence exclaimed, "You mean Toso Silver?"

"Toso silver?" Richard blinked, "I'll take it baras silver, or metal palladium." But it doesn't matter, I think we're talking about the same thing, and I really need it, if you have enough here, Master Lawrence, you can help give me some. ”

"I do have them here, and there are enough of them. Lawrence spoke, and then his tone changed, "But the question is, why should I give it to you? Am I in any good of giving you the silver?" Hmph, boy, don't tell me, you're going to give me money, do you think I'm the one who is short of money?"

"This—" Richard raised his eyebrows, glanced at Lawrence, thought for a moment, and said, "How about I exchange knowledge for ...... Can you improve your existing technology?"

"Help me improve my existing technology?" Lawrence was stunned for a moment, and then burst out laughing, as if he had heard the funniest joke in the world, "Hahaha, boy, are you stupid, or are you arrogant? You think, you can't understand anything, you think you can improve my technology? It's ridiculous!"

"This kind of thing, if you don't try it, how can you know if it's true or not?" Richard was not angry, kept calm, looked around at the wooden shelves, saw a black case clock nearby, reached out and took it, and put it on the table in front of Lawrence.

Richard pointed to the black-shelled clock, and said in a serious voice: "Master Lawrence, this clock is one of your proud works, but have you noticed one of his problems, that is, the movement of the hands is unstable. Sometimes it's a little faster, sometimes it's a little slower?

Although this kind of problem can be solved by finishing, it cannot be completely improved. And I can help you basically solve the problem through technology upgrades, I don't know if you want to know how to do it. If you're wondering, then I need three things right now, quill, ink, and paper. ”

After listening to Richard's words, Lawrence looked at Richard and stared at Richard's eyes, as if to see Richard through.

After a long while, Lawrence made a decision, turned his head to look at the two students next to him, and shouted, "Give him what he wants!"

"Well, yes. When Muto and Lake heard this, they did not dare to say anything more, and quickly brought a brand new quill pen, a bottle of ink, and a papyrus scroll to the table.

Richard didn't say much, but unfolded the papyrus scroll, dipped it in ink with a quill pen, and quickly drew a diagram of the parts and how they worked.

It took dozens of minutes to finish an extremely complex drawing, and he reached out and pushed it in front of Lawrence, and Richard made a gesture of please.

Lawrence looked down, his gaze resting on the scroll, and took a serious look. At first, he was slightly repulsed, and the expression on his face seemed to say, "Nonsense!"

Then his expression changed slightly, and it became: "It seems to be a little interesting." ”

And then it was, "How can this place be made like this?"

And then: "This place is a little hard to understand, but it feels amazing." ”

And finally: "This ...... This...... This...... If this can be realized, it will be really amazing, and it can solve all problems!"

Lawrence kept looking at the drawing, and for most of the hour did not make any other movements, as if he were petrified, because his eyes were blood-red after not blinking for a long time.

Lake and Muto were a little worried next to them, and couldn't help but lean over and whispered, "Teacher, you...... Are you alright?"

"Hmm-" Lawrence moved, as if coming back to his senses.

"Whew-"

Lawrence let out a long breath, turned his head to look at Richard, showed a somewhat strange expression, and said in a loud voice: "Boy, you thought of this way of improving the clock?"

Richard was noncommittal: "In any case, it helped you improve your technique, didn't you?" as agreed, Master Lawrence, could you give me the Toso silver?"

"Okay, that's for you. Lawrence listened to Richard's words, and did not talk nonsense, looked at his students, and quickly commanded, "Give him all the toso silver in the storehouse." ”

"All of you, Sensei?" Hearing the voice, Muto and Lake couldn't help but confirm.

"All!" Lawrence affirmed.

"Uh, okay. Muto and Lake ran into the next room through a small door, and after a while, the two of them carried out a heavy iron box and placed it in front of Richard with a muffled "bang".

When Richard opened the iron box, he saw that there were pieces of cast metal palladium, neatly arranged like gold bars.

Nodding with satisfaction, he closed the iron box with a "snap", and Richard looked at Lawrence and said, "Master Lawrence, thank you." After that, pick it up and go.

"Slow down, please wait!" Lawrence shouted.

"What, Master Lawrence?" Richard stopped and looked at Lawrence, "What's the matter?"

"Hmm...... It's still the same question as before. Lawrence spoke, paused, and continued, "I admit that the way you improved the clocks was effective—very effective, so to speak, far beyond my expectations. That's why I'm curious how you came up with it.

According to my thoughts, this should never be something you did alone!

After all, I have studied the drawings all my life, and I have only reached the current level, how can you be better than me at such a young age? Besides, you don't have drawings yet!

Tell me, how the hell did you get this technology?"

Richard looked at Lawrence and smiled: "Master Lawrence, this question seems to be beyond the scope of our transaction, and it has touched my privacy." ”

Lawrence spoke up: "Since you say so, it means that you can actually tell me, right? Then what do you want me to exchange? I gave you all the silver, there really is none, but I have many other things, such as gold, silver, and precious stones, as long as you want, I can give you." ”

"I have those. Richard said, his eyes flashing, and said, "If Master Lawrence, you really want to know my secrets, why don't you exchange your own secrets." ”

"My secret?" Lawrence was stunned.

"Yes, your secret. Richard nodded, and said in the affirmative, "Aren't you curious how I got the technology to improve clocks? Actually, I'm also curious about how you know how to make clocks and guns." Neither clocks nor firearms exist in this world, how did you make them, and why did you make them?"

"This—" Lawrence spoke, leaning in his wheelchair, his expression a little cloudy, and he didn't speak for a long time.

The atmosphere in the room became a little dull.
