Although Huang Chengyan said vaguely, Sun Ce had already guessed the reason. There were two crossbows missing in the baggage camp, and Huang Chengyan must have been suspicious, but there was no evidence, so he couldn't talk nonsense, so he could only take precautions and find an opportunity to give Sun Jian a golden silk brocade armor, and be prepared.

With Sun Jian's martial arts, even if he is alone, the possibility of assassinating him at close range is extremely small, so the other party wants to steal the crossbow. Since it is a long-distance attack, unless it is a sharpshooter like Lu Bu and Huang Zhong, they usually do not choose a vital part such as the throat, but choose the chest and abdomen. The effective range of the three-stone crossbow is one hundred and twenty steps, and if you want to shoot through the fish scale armor worn by high-ranking generals, you must at least have a range of one hundred steps. But with the Golden Silk Brocade Armor, even this distance could not be penetrated, unless he rushed to within fifty steps in front of Sun Jian.

With this close-fitting gold silk brocade armor, it is possible for Sun Jian to be injured, but the possibility of being fatally injured is extremely low. If he really wants to be shot in the throat by an arrow at this distance, it can only be said that Sun Jian's life should be like this.

"Thank you, sir, thank you." Sun Ce gave up his hand again and again. Jiang is still old and spicy, and Huang Chengyan's mind is much more thorough than his.

"That's the filial piety of the captain, I'm just doing it." Huang Chengyan remained silent.

Sun Ce couldn't help laughing. Needless to say, it was Huang Chengyan who put the credit on his head. This old fox is really leaky.

"It's an honor to have my husband's help." Sun Ce arched his hand and sincerely expressed his gratitude to Huang Chengyan, which can be regarded as officially accepting Huang Chengyan as a confidant. Huang Chengyan knew it well and returned the gift again and again. Zhou Yu was also exquisite, and immediately congratulated Huang Chengyan. From now on, the two are true colleagues.

The big stone in his heart was put down for the most part, Sun Ce's tense nerves relaxed a little, and he finally had the heart to look at Huang Chengyan's siege vehicle. He glanced at it. "This siege vehicle is the easiest to break at the top, right?"

"Exactly, what does the captain think?"

"The arc of your dome is not big enough, and the weight above can still easily hit head-on, no matter how strong it is, it is useless."

"The arc is too big, it's hard to machine, and the strength is compromised."

"Why don't you make a triangle?" Sun Ce picked up three wooden strips from the ground and formed a triangle. "Of all the shapes, the triangle is the most stable, and it is difficult to cause real damage unless it is in the center of the top and a heavy object falling above it."

Huang Chengyan stared at the triangle in Sun Ce's hand for a while, woke up like a dream, and hurriedly beckoned: "Achu, hurry, write it down." I thought about it for a long time and finally found the answer, triangle, triangle is the best structure. ”

Huang Yueying glanced at Sun Ce proudly, and said in a playful voice: "Ah Weng, I have already written it down." Captain, take a look at our stone thrower, can you give me some advice? ”

"Catapult?" Sun Ce was surprised. Stone-throwing machines have been around for a long time, but like other technologies, they are not taken seriously and are often in danger of being lost. During the Battle of Guandu, Cao Cao reinvented the stone thrower to deal with Yuan Shao. Huang Chengyan also invented the stone throwing machine?

Sun Ce followed Huang Chengyan and Huang Yueying to the stone thrower, took a look, and was a little disappointed. The stone throwing machine is a stone throwing machine, but the size is too small, and it is used to drag the hair stone by manpower, so you don't need to try it to know that the power is limited.

"Does the captain have any suggestions for improvement?" Huang Yueying squinted at Sun Ce with a provocative look.

"How heavy is your hair stone, and how far is the range?"

"Twelve pounds of hair stones, two hundred paces of range." Huang Yueying pursed her lips and said, "This is the record of "Fan Li's Art of War". ”

"Technology is not the older the better, if the future generations cannot surpass the predecessors, wouldn't it be a shame to the sages?" Sun Ce chuckled and turned to Huang Chengyan. "Sir, your stone thrower is very well designed, I have nothing to say, only two suggestions."

"Do you really have a suggestion, two more?" Huang Yueying pursed her lips and exclaimed in surprise.

Sun Ce ignored her surprise and said very seriously: "First, the lethality of twelve catties of stones is limited, and I am afraid it is not enough to destroy the city wall. You can design a longer range, more powerful stone thrower, and instead of asking for everything, focus on breaking down the city, and use it intensively when the time comes, blasting through a section of the city wall in one go. ”

Huang Chengyan groaned and nodded again and again.

"We've already thought of this." Huang Yueying raised the silk book in her hand. "You're going to talk about the second one?"

Sun Ce glanced at her and pouted. "Why don't you say what you think first, or when the time comes, I will say that I am not creative."

"Uh......" Huang Yueying glanced at Huang Chengyan secretly and shrunk her neck. Huang Chengyan said with a smile: "Captain, don't listen to Achu, we just have this idea, and we haven't implemented it yet." Building a larger catapult requires more people, which requires a long period of training, otherwise the number of people is doubled, the increase in strength is limited, and the efficiency is not high. ”

Sun Ce nodded. This is a real expert, he thinks it through. "My second suggestion is to solve this problem. You can change the manpower tow launch to a counterweight launch, and the person only needs to be responsible for loading the stone and resetting. As long as the counterweight is fixed, the force can be fixed for each launch, and the range is only related to the stone to be thrown. ”

Huang Chengyan's eyes lit up and he nodded again and again. Huang Yueying was also surprised when she heard this.

"It's as simple as that?"

"yes, it's easy." Sun Ce smiled and pretended to arch his hand. "Laugh, laugh."

Huang Yueying blushed, pouted, turned around, and muttered in a low voice while writing in a hurry: "I hate it!" It's annoying! Such a simple way, why didn't I think of it? ”

Huang Chengyan shook his head, unable to hide the loss in his heart. "Captain, I have studied wood for half my life, and I claim to be the only one in the world, but I am ashamed to say a few words as well as the captain."

Sun Ce was also embarrassed. Technology needs to be accumulated, and without two thousand years of technological progress, he may not be able to know more than Huang Chengyan. I was in a good mood today, and I said a few more words for a while, but I hit the Huang family's father and daughter hard. That's exactly what he's been avoiding. No matter who you are, no matter what you do, self-confidence is very important. He is not an all-powerful traverser, he can do everything, he can only be a guide, and most of the things still need to be done by people of this era.

"Sir, the stone of his mountain can attack jade, and I am that stone. If it is helpful to Mr., it is also based on the large amount of work that Mr. has done before, and it is not out of nowhere, and the books that Achu read for me and the truths he taught for me are the source of my suggestions. Without her, I wouldn't have been able to tell why. ”

Huang Chengyan smiled slightly and glanced at Huang Yueying. Huang Yueying turned her back and didn't dare to turn around, she could only see the blood-jade earlobes.

At this time, a fast horse bypassed the position and came to Sun Ce. The knight on horseback turned over and dismounted, walked quickly in front of Sun Ce, and whispered: "Captain, the general asks you to return to the Chinese army camp immediately." ”
