This meal was eaten for nearly an hour, and when the moon was in the sky, the old man Chu reprimanded the two children with a straight face, and let Tan Jiaotou temporarily withdraw from the door, he and Chu Jia and Chu Ding changed a small table, on the surface, they were still talking about alchemy, but the main topic was around the improvement of the fire gun.

With a little drunkenness, Qin Baichuan's brain is also quite flexible, and he said the concept of modern guns that he can think of and explain, such as what the longer the barrel, the longer the range, for example, if you build a spiral device inside the barrel, so that when the bullet is fired, it will have a rotational speed, which can increase the lethality, and for example, the firearm can actually be expanded twenty times, and then two wheels can be installed to make an artillery, and so on, etc., the three old men of the Chu family were dumbfounded, and Qin Baichuan himself was also dry-mouthed.

"Brother Qin, let's not talk about these things about artillery for the time being, let's still focus on the present." The more Qin Baichuan spoke, the more excited he became, but Old Man Chu interrupted him with a wave of his hand: "Let's start with the firecracker, the old man will improve the firecracker tomorrow according to the mechanism inside the honeycomb, and then you will stand next to you, what effect do you want, you tell me, I will take my brother to make a few modifications!" I think that the top priority is nothing else, but the white phosphorus you mentioned, if this problem cannot be solved, even if we can create the fire gun in your mind, it will eventually be a burning stick! ”

"No problem, Baichuan has been in the Chu family for this time!" Qin Baichuan was already drunk, and said with a flushed face: "Not only to improve the firecracker, if you can, add a telescope to the firecracker, and it is best to get a few sniper rifles out!" ”

"Sniper rifles?" The three old men didn't understand, but before they could ask, Qin Baichuan suddenly slapped his head: "I'm the second Ao, how did I forget them!" ”

"Who? Who forgot? Qin Baichuan was startled, but he startled the old man.

"Juggul, Abraham!" Qin Baichuan said excitedly.

"Those two Westerners?" After a period of contact, the old man also figured out their names, pondered for a while, and said: "What kind of Zhu Geguli you are talking about, it seems that he is quite proficient in these strange and obscene skills, and he personally created the telescope you said when he was in the Chu family's workshop......

"Really?" Qin Baichuan's eyes lit up, he hadn't seen them for a month, and when he heard that they had built a telescope in the Chu family's workshop, Qin Baichuan still couldn't believe it. In modern times, telescopes are actually a combination of concave-convex mirrors, but it is not easy to refine transparent glass in this era, let alone what concave-convex mirrors to do?

"How can the old man lie to you?" Old Man Chu nodded and said with a smile: "That Zhu Geguli still has two brushes, and he has always been very enthusiastic about people since he came to the workshop, and sometimes he keeps pointing fingers, as if saying that our craftsmen are doing something wrong...... Unfortunately, the language barrier and the craftsman ignored him. Later, he took matters into his own hands and drove the carriage around most of the Gangneung, and collected some stones that were either broken or burned, and he really fiddled them out. ”

"Huh? Old man, when we went to the workshop today, why didn't I see the two of them? "Qin Baichuan was a little broken, when he took in two Westerners, he had the intention of draining their value, but when he returned to Jiangling to quarrel with his eldest wife, he forgot about them.

"Every seven days, they have to return to the cult of Bliss early, as if they are going to bow down to something...... Anyway, it's just some religious etiquette, we don't understand, and we don't ask. Old man Chu also had a glow on his face after drinking: "Even if you ask, they can't understand what they say." ”

"What do you do to bow down...... Uh, old man, you're talking about worship, right? Qin Baichuan smiled bitterly and said: "They may be primitive Christians, and every Monday, that is, every seven days, they have to kneel down in front of the gods and confess what they have done, just like going to worship the Buddha on the fifteenth day of the first day of the Great Song." ”

"Oh, I don't understand, I really don't understand." Old Man Chu waved his hand and said with a smile: "Listen to what you mean, in terms of improving the fire gun, these two Westerners can help?" ”

"If nothing else, there is no problem, not only the fire guns, I'm afraid they also have some opinions on how to refine white phosphorus!" Qin Baichuan rubbed his palms excitedly: "I'll write a note later, and the old man Lao Chu will call them over early tomorrow morning, I'll tell them!" ”

"Hmm." Old Man Chu nodded lightly.

At that moment, after saying almost everything, Old Man Chu asked Qin Baichuan to go back to the room to rest, while he and his two brothers carefully closed the door and quietly discussed the improvement of the fire gun and the production of bullets. Under the leadership of Jia Ding, Qin Baichuan came to the Chu family's guest room to rest and sleep well.

Early the next morning, the old man Chu went to the room with blood-red eyes to wake up Qin Baichuan in person, seeing that the tiredness on the old man's face was obviously that he hadn't slept all night, Qin Baichuan felt extremely guilty. The old man is so old, and he has to help himself unconditionally, Qin Baichuan has some bad feelings in his heart. However, he is a theoretical player, and he doesn't know anything about how to draw, how to use clockwork, and how to use the machine.

Old Man Chu brought the design drawings that were discussed with Chu Jia and Chu Ding last night, Qin Baichuan took the drawings in his hand, and Old Man Chu patiently explained on the side, this time the old man handled the improvement of the fire gun is mainly reflected in three aspects.

The first is the structure of the gun body, according to Qin Baichuan's suggestion, the old man Chu first changed the grip of the gun to a semi-arc, in order to resist the recoil of the gunpowder explosion, the butt of the gun was made of wood, from the original nest in the hand to be able to be on the shoulder, the gun barrel has also been lengthened, and from the original single barrel to a double barrel, which is quite similar to the meaning of a double-barreled shotgun.

The second is the loading device, Qin Baichuan mentioned earlier, tamping the gunpowder is too troublesome and delays time, so the old man Chu opened a rectangular hole in the position of the fire gun near the tail, that is, the original fuse, according to the folding principle on the door, the rectangular hole is covered with two steel hoops that can be wrenched, and after the two bullets are fired, only the steel hoops need to be broken and filled with special bullets.

The third change is reflected in the trigger device, this idea is almost Qin Baichuan's suggestion, that is, the trigger is added in the appropriate position, the internal structure of the trigger adopts the mechanism of a honeycomb, and the high-density gear is combined with the clockwork to achieve the shooting effect. Qin Baichuan saw the mechanism inside the hive with his own eyes, and after the old man Chu explained, even if there was no impetus from gunpowder, the bullets inside would be able to fly out at least a zhang away.

The most core part of the improved firebolt is embodied in the firing pin attached to the trigger, this firing pin Old Man Chu's idea is that the flint can be used, and the third part of the bullet that Qin Baichuan said last night, that is, the place where the white phosphorus is stored, is also all made of flint, so that the firing pin is ejected, and the flint will inevitably rub out sparks and ignite the white phosphorus, and then achieve the effect of igniting the gunpowder and forming a jet.

After Qin Baichuan figured out the structure, he couldn't put it down and held the drawings, and had to sigh with emotion, modern people have always underestimated the ancients, but they don't know that under the limitation of special conditions, the wisdom of the ancients is infinite, at least the old man Chu has turned some of his imaginative ideas from theory into reality.

"Brother Qin, are you still satisfied with the improved firecracker?" Although his face was full of tiredness, the old man was also happy when he saw his achievements being praised.

"Satisfied, so satisfied!" Qin Baichuan excitedly returned the drawings to the old man, licked his lips and said: "This is only the first generation of improvements, if the effect is good, I think it can be further improved on this basis, and strive to make the sniper rifle I said last night!" ”

The old man didn't have any concept of the sniper rifle, and he didn't worry about it, so he said: "According to Brother Qin's point, the power of this torch will inevitably be greatly improved after it is improved, and with the experience of casting the hive and the previous firecracker, the old man is also confident that he will cast a new firearm in a short time, but it is just ...... The key to determining whether the firearm can succeed is still in the bullet that Qin Xiaoge said. No, Chu Jiatian got up and went to the mass grave before dawn, wanting to collect some bones and see if he could extract them from them. ”

Qin Baichuan sighed again, clenched his fists sincerely, and said: "Old man, no matter whether the fire gun can be successfully developed in the end, the kindness of you and several old men to Baichuan will not be forgotten by Baichuan. ”

"You're polite, you can make achievements in strange lewd skills, which is also what the old man wants." Old Man Chu waved his hand indifferently, and said, "Little Brother Qin, you have read the firecracker, do you still have any suggestions for revision?" ”

"It's gone." Qin Baichuan shook his head: "You always have to make a look at the specific effect, otherwise you will never know where there are shortcomings." ”

"If not, then ask Brother Qin to sign a name here and press his handprint." Old Man Chu had already prepared, took out a contract from his arms and put it on the table.

Qin Baichuan glanced at it, this contract was actually a transfer letter, which was clearly written on it, to the effect that Qin Baichuan had a strong interest in the Chu family's Fu Python Mountain industry, and after careful negotiation between the two parties, Qin Baichuan acquired it for 50,000 taels of silver, that is to say, as long as Qin Baichuan signed his name, Fu Python Mountain would have nothing to do with the Chu family.

"Old man, this ......" The old man gave himself a big piece of fat meat, Qin Baichuan couldn't bear to swallow it, the key is that there is also a silver receipt attached to the back of this contract, which reads "The money has been paid", obviously the old man does not take a penny.

"Brother Qin, you are a smart person, there are some things that don't need to be said too clearly." Old Man Chu didn't have any distressed look, and said: "That little thing in Fu Python Mountain is a piece of fat for you, for King Yi, even for the emperor, but it is a hot potato for the old man." The old man is old, dragged his family with him, and does not want to get involved in any political disputes anymore. ”

"Old man, I understand all these things, but I always feel uncomfortable." Qin Baichuan smiled bitterly.
