In fact, if Lu Ren really wanted to get the stone cart out, he didn't need to go to Liu Ye at all. But Lu Ren didn't know when he started, and he vaguely felt that the things he got out were not too good, so he chose to find Liu Ye and get Liu Ye's stone cart pattern, and he made appropriate improvements here.

But to be honest, when Lu Ren got the pattern of the stone cart in Liu Ye's hand, Liu Ye explained to Lu Ren that it was part of the missing catalogue in the book "Mozi" that he had accidentally obtained. However, according to the records in the existing book "Mozi" at that time, Lu Ren believed that the stone cart in this pattern should be an improved and developed version of the "throwing cart" developed by Mozi during the Warring States Period.

Because Mozi's "throwing machine" is only a kind of medium and long-range striking equipment that is heavily placed and fixed on the city wall, the range is relatively short, and it depends on the height of the city wall itself to add a certain amount of range, and the main purpose is to destroy the opponent's ladders, well railings, and large siege equipment such as rushing cars, and in short, it is a kind of combat equipment that can only be used for defense.

However, Liu Ye's stone truck has a high parabolic apex and a relatively long range, so it can shoot from low to high, and from the point of view that there are movable wheels at the bottom, this already has a strong tactical aggressiveness, which is contrary to the "conformist" and "non-offensive" ideas that Mozi has always advocated. It is said that this is also because Lu Ren has Cai Yan, a talented woman who is proficient in literature and history, and it is difficult for Lu Ren not to understand the leading ideas of these famous masters, so Lu Ren deduced that Liu Ye's stone cart should be improved by Mozi's descendants on the basis of Mozi's "throwing machine" prototype.

And after Cai Yan learned about the function of the stone cart, he once half-jokingly put forward a bold assertion that even Lu Ren was shocked to hear, that is, Qin Shi Huang's car had been thrown from a distance with a heavy object weighing hundreds of catties. Legend has it that this was done by a certain divine warrior, and Qin Shi Huang's car was also smashed, but Qin Shi Huang was in another car at that time and avoided a catastrophe, which is the origin of the idiom "mistakenly hit the auxiliary car".

But Cai Yan has grown a lot of insight after experiencing a lot of things personally, and when he saw the stone cart, he had some doubts about that warrior. Because people who can throw heavy objects weighing hundreds of pounds over such a long distance and accurately hit the target. In terms of courage alone, it's still above Xiang Yu, the overlord of Western Chu.

However, there should be no reason why a person with such courage would be easily killed by the Qin army, or that he did not appear in the subsequent anti-Qin uprising after escaping, which is a little unreasonable. Therefore, Cai Yan thinks that this warrior who threw heavy objects is likely to be just a self-sacrificer who stood up to induce the Qin soldiers and cover the safe evacuation of his companions, and it should be this kind of stone cart that really threw heavy objects and hit Qin Shi Huang's throne car.

On the other hand, Qin Shi Huang was also known for his great joy and pride, and it is likely that he was unwilling to admit that he had almost died in a broken mechanism, and therefore deliberately exaggerated the Assassin's abilities. Gain some face for yourself while concealing the facts. Perhaps it can be explained that even if an assassin is so brave and powerful, but he can't hurt himself in the slightest, then other people who want to murder him have to consider whether they have enough weight.

As for the stone truck...... One word, ruined! At the same time, destroying all relevant materials and preventing people from making relevant things is also a kind of thing to save the emperor's face. Perhaps this can also explain why Qin Shi Huang, an extremely aggressive emperor, had such a developed military industry under his command, and all kinds of ordnance were so powerful and advanced. However, it has not developed the reason why the stone cart that existed in the Spring and Autumn Period and the Warring States Period and can be used as a siege weapon.

After Lu Ren obtained Liu Ye's stone wheel pattern, he made certain improvements to the existing stone wheel according to the finished stone wheel of later generations. Like the winch structure with a scale, which can ensure the stability of the trajectory to a certain extent, is one of them. In short, Lu Ren knew that Liu Ye did not go to the front line of Guandu with Cao Cao to participate in the battle as in history. Therefore, it is up to Lu Ren to find a way to correct and complete these things. And now these stone carts made by Lu Ren have finally appeared where they should be......

————————————————————

Cao Cao glanced at the stone cart that had already been "loaded with ammunition" and was just waiting for the "triggering machine", and asked Lu Ren in confusion: "Yihao." What should be done now? ”

Lu Renzheng stared at a red eye, holding a telescope to look at the earth mountain opposite: "When the archers of the Yuan army have all gone up to the earth mountain to release arrows, Cao Gong, you can order the throwing of stones." In the past few days, Cao Gong and the soldiers should have been holding a lot of anger in their hearts, right? In a while, Cao Gong and all the soldiers can vent their happiness! But don't rush it just yet. If it was too early, most of the archers of the Yuan army would not dare to go up to the Tushan Arrow Tower. ”

Cao Cao raised his eyebrows, glanced at the stone cart waiting to depart beside him, nodded lightly, and then casually took out his binoculars and looked at the Tushan Arrow Tower opposite. As the sun is getting higher, a lot of Yuan army archers have gathered on the Tushan Arrow Tower, and some of them are even already firing their bows and arrows, in order to fool the Cao Ying soldiers to have some fun.

It's really a shame that Cao Cao has a temperament, ignoring these scattered arrows, and waited until the archers of the Yuan army were almost standing on the dirt mountain and were about to open the bow and release the arrows, Cao Cao suddenly gave an order: "Beat the drum, throw stones!" ”

The drum beat sounded in Cao Ying, followed by the sound of flying stones breaking through the air! In the first few pulls, because the soldiers of Cao Ying were still a little unaware of the ability of the more than 100 catapults, they were a little hesitant in their hearts, so the speed of loading and throwing stones was a little slow. But soon, they saw the amazing power of the stone cart - dozens of pounds of stones, really thrown out of the distance than a bow and arrow, and the lethality is not to mention! I saw that Yuan Jun on the top of the arrow tower on the earth mountain screamed again and again, and it was okay to be smashed into broken bones and escape with injuries. It's really smashed, that is, the pulp is all over the place, and he died! Also archery? Handsfree! How many guys have the audacity to shoot arrows under the attack of the "meteor shower"?

As a result, Cao Bing, who had been suppressed for several days, and who was full of sullen breath in his chest, immediately cheered and morale was greatly boosted, and the work in his hands was getting faster and smoother. Just like Lu Ren just said, now he is not killing the enemy, but venting, desperately!

Almost all the generals were clapping their hands and exhaling in relief, and even Cao Cao, who had always been calm, was looking up to the sky and laughing. It's just that when Cao Cao's eyes fell on Lu Ren's body again, he found that Lu Ren was standing on the main road in the camp, and looked at the screaming Tushan on the opposite side in a daze, but there was no joy. Cao Cao frowned slightly, and was about to step forward to talk to Lu Ren, but saw Lu Ren take out the bamboo flute from the cloth bag on his waist with his backhand, and slowly brought it to his mouth.

The sound of the flute is not a joy. The prelude may not be anything too special, but it is a bit solemn and solemn. Suddenly, the flute sounded around, bringing out a bit of golden iron horse, tragic and majestic. The whole piece of music gives people the feeling of a calm and calm swordsman, when encountering the enemy, first calmly draw the sword to match, and then use the big open and close, real but not flashy tricks to defeat the opponent, and finally calmly shake off the blood beads on the sword......

In the already noisy Cao camp, Lu Ren's flute music was actually muffled by this noise, and people who were a little farther away were basically inaudible, but Cao Cao behind Lu Ren could hear it clearly, and even heard the killing intent that Lu Ren had forced to hide under his calm expression from the rhyme. Cao Cao was slightly stunned for a while, but did not step forward to disturb Lu Ren.

Soon after the song ended, Lu Ren slowly turned around, but his face was full of exhaustion. Raising his eyes and looking at Cao Cao, Lu Ren seemed to have almost no strength to speak, so he just bowed his hand to Cao Cao and dragged his heavy steps to leave.

Cao Cao also glanced at Lu Ren a few times, and when the two were about to face each other, Cao Cao suddenly asked: "Yihao, there is a bit of battle in the meaning of this song, but does it have its name?" ”

"Canglang Sword ......" Lu Ren's voice was really weak.

"Canglang...... Sword Fu ...... The waves are angry, is the sword solemn? Cao Cao muttered this, saw Lu Ren walking forward with his head down, stretched out his hand and pressed Lu Ren's shoulder and said, "What does Yihao want?" ”

Lu Ren turned his head and smiled reluctantly at Cao Cao: "I haven't slept well for several days, I can't stand it at this time, and I want to go back to the tent to sleep with my head covered." Cao Gong, now the dilemma of the Tushan Arrow Tower has been solved, if Yuan Jun still dares to go upstairs and shoot arrows, it can only be his own humiliation, I think they will not dare to use this method of the Tushan Arrow Tower anymore. A little later will allow the sergeant to point the carts at the crossing ahead...... With throwing stones from afar, bows and crossbows in the middle, and knives and guns at close range, it is difficult for the Yuan army to approach the edge of the village...... Ahem!! ”

Saying that, Lu Ren suddenly coughed violently, just like before in the Xuchang Shangshu Mansion, and quickly coughed and squatted down. When Cao Cao hurriedly helped Lu Ren up, Lu Ren's sleeve covering his mouth always covered his lips, and then he left in a hurry.

Cao Cao saw a little strange appearance on Lu Ren's body, and couldn't help frowning, and then squinted a pair of triangular eyes to look at Lu Ren's back, and said secretly in his heart: "Wen Ruo and Changwen came to write not long ago to say that Lu Ren's health is deteriorating, and this is really the case when I see it today...... It's a pity, Lu Ren is still of great use to Lonely. ”

didn't say how Cao Cao was, just said that Lu Ren fell on the couch after returning to the tent. Of course, Fang Cai was acting in front of Cao Cao, but he played a little trick with Xun Yu and Chen Qunna that day here in Cao Cao. But at this moment, Lu Ren was already physically and mentally exhausted, but it was true. After being busy for several days, Lu Ren is really tired now, and his physical strength and spirit are almost close to the limit of his body.

As soon as he lay down for a while, Guo Jia hurriedly rushed into the account and asked, "Yihao, are you okay?" ”

Lu Ren, whose eyes were almost open, smiled at Guo Jia reluctantly: "Old Guo...... Don't worry, I'm fine, I'm just too tired. Don't bother me, let me get a good night's sleep......"

Guo Jia asked very uneasily: "Is it really okay?" I see you're coughing so badly...... No, I'll find a military doctor to show you! (To be continued......)
