Under the city of Wuguan, fierce battles are raging.

In the face of Sima Yi's army, Deng Zhi didn't dare to take it lightly and show weakness or something, he didn't dare to play at this time. Once Sima Yi finds the weak link, even if he entangles Sima Yi, he may not be able to swallow it.

Therefore, as soon as he made a move, he went all out and used all the more than 30 thunderbolts that Wei Ba spent more than ten days building for him. According to Wei Ba's suggestion, he did not install these thunderbolts on the city wall, but placed them behind the city wall, and the people on the city wall instructed the people who operated them to adjust the thunderbolt according to the actual strike effect.

In this way, although he lost part of his range and could only cover a distance of fifty paces to the outside of the moat, he was very haode to protect himself. Not only to protect those who operate the Thunderbolt, but also to protect the Jishu secret of the Thunderbolt.

The Thunderbolt that Wei Ba is building now is different from the original Thunderbolt. On the one hand, it is the refinement of the details, Wei Ba has optimized the structure of the Thunderbolt through various calculations, so that the range of the Thunderbolt is longer, and on the other hand, it is a change in power. If the former is a quantitative change, the latter is a qualitative change.

The thunderbolt is a weapon that has existed very early, it has appeared in the Warring States period, it was called the thunderbolt car at that time, and it was later lost, when Cao Cao was between the official crossings, according to the records of the ancient art of war, this weapon was put on the battlefield again, and it was given a scary name called the thunderbolt car, in fact, the official name is also called the thunderbolt or the stone thrower. This weapon was used until the Song and Yuan dynasties, before the appearance of artillery, this was the well-deserved king of the battlefield, a sharp weapon for attacking and defending the city, and the same as the heavy crossbow on the battlefield.

But this weapon has one significant flaw, and that is the power system. From the date of invention until the withdrawal from the battlefield after the Song and Yuan dynasties, the Chinese' stone throwers were launched by human pulling, rather than with counterweights. Manpower pulling. You need a lot of people, and if there are too many people, it will inevitably be uneven. The more times you pull, the more people will get tired, so every time you launch, the liliang changes. The change of liliang will cause a change in range. At the same time, the different forces in different directions will also cause the overall deflection and different changes in the shooting angle.

In a word. It is difficult to stabilize the range of a catapult pulled by manpower, and the accuracy is not enough.

These two problems can be solved by replacing human pulling with counterweights. First, the force is constant, and the firing range can be guaranteed, and second, there will be no lateral force, and the firing angle can be controlled within a very small range. In other words, the accuracy of the stone throwing machine can be greatly improved.

This has been fully proved when Wei Ba attacked Jianzhang Palace. As long as the weight of the stone bullet is controlled within a range, the landing point of the stone bullet will basically not have much error.

Before the invention of the sniper rifle, such accuracy was already called the extreme, enough to be compared with the giant crossbow.

This improvement is very useful, but it is not complicated to do. It's like stirrups, you can basically learn it just by looking at it. Wei Ba can't guarantee that he will never be known, but one more day of secrecy will give him an extra advantage. At this point, as Wei Ba, who has been influenced by modern industry, has a sensitivity that others cannot aspire to. Even Deng Zhi and Zuihou have not been able to change his decision.

Deng Zhi was originally a little unhappy, but when he saw that those thunderbolts were more than twice as accurate as the Wei army's similar weapons, and the nest carts that pushed the Wei army to the front of the formation were all broken and broken, and the archers and lookouts in the nest car fell one after another like birds throwing into the forest, and he probably guessed the reason why Wei Ba did this, and the unhappiness in his heart disappeared.

Even with the help of these thunderbolts, Deng Zhi's pressure was still not small, and there was only one reason, Sima Yi's military advantage was too obvious.

Although Deng Zhi tried his best to resist, Sima Yi still used nearly 100 trench filling vehicles to quickly fill in the moat, and erected a passage about 50 steps wide in front of the city. Sima Yi set up three phalanxes of 5,000 people in front of the formation, and every time he went into battle, they were 5,000 people, and in front of the city wall of less than 300 steps, they were divided into dozens of points to attack at the same time, with an average of nearly 100 people at each attack. In front of the city there were warriors clinging to the wall, behind there were archers in the nest cart to carry out targeted strikes, and at the same time to provide information to the companions under the city on the head of the city, on the outside of the moat, there was a phalanx of 5,000 archers with non-stop firing for cover. The offensive was methodical and steady, and once the physical strength of the soldiers decreased, he would fight again with 5,000 men, without giving Deng Zhi a chance to breathe.

If it weren't for the rapid removal of those nest cars in the thunderbolts, and the fact that there were crossbow cars to offset the disadvantage of insufficient troops, Deng Zhi believed that in the face of Sima Yi's offensive, he would not be able to hold out for three days.

In the final analysis, this is still a gap in strength, in the face of absolute strength, no matter what tricks you have, as long as the opponent does not make mistakes, it is difficult for you to have any chance to turn defeat into victory.

It was only a half-day battle, and the walls of Wuguan were smeared with blood again, and there were many corpses, rolling stones, smashed ladders, and arrows like weeds under the city walls, which were much more than the last time Hu Zun attacked for a day.

Deng Zhi also felt strong pressure for the first time. He somewhat understood that Wei Ba Weishenme did not advise him to defend the martial pass, Sima Yi was definitely not an ordinary opponent, just based on his preparation for ten days before the siege, and the ruthlessness of the siege at the expense of casualties after the siege began, he could guess his ability. Last time, if it weren't for Wei Ba's strong suggestion that Zhuge Liang increase his troops in Fangling, in the face of Sima Yi's almost crazy close attack, Meng Da probably wouldn't be able to defend Fangling.

Seeing Wei Ba walking on the city wall, Deng Zhi shook his head tiredly, pointing to the immovable phalanx outside the city, and the command platform behind the phalanx. "Ziyu, this person is a fierce enemy."

Wei Ba grinned, and said in his heart, this is a ruthless character who can suffocate Prime Minister Zhuge to death in the Northern Expedition, and can be said to be the most outstanding military strategist in the middle of the Three Kingdoms. It's just that he was unlucky, and I postponed the time to shine.

"What does the general think?"

"Hold for two more days, consume their morale more, and then look at it, I don't believe he can keep attacking like this." Deng Zhi looked at Wei Ba and laughed: "I saw the sailors of the Wei army just now, the number has decreased a lot, and the building ship is gone, is it a success?" ”

Wei Ba smiled slightly: "Hongfu of Emperor Bixia." Fortunately, he did not disgrace the general's mission. ”

Deng Zhi daxiao, patting Wei Ba's shoulder, walked slowly on the city wall. "Ziyu. I'm sure you'll be able to fight them off, but I didn't expect you to do it so quickly. Speaking of which, it's still terrifying. The prime minister values you so much, I was a little unimpressed at first. Now it seems that the prime minister still has the wisdom to know people, and I can't reach it. ”

Wei Ba nodded quietly and agreed: "Of course." The prime minister is a rare genius in a hundred years, and it is beyond our reach. ”

"You're not bad, among young people, it's rare to see someone as capable as you." Deng Zhi raised his head and sighed lightly: "There is a prime minister who is strategizing, and there is a young man like you who is running for his life." As long as you cooperate with the tacit understanding and recover the Han Dynasty, what is the difficulty? ”

Wei Ba nodded again and again, without saying a word. He knew what Deng Zhi wanted to say, but he didn't think so. It's not that I don't want to cooperate with the prime minister. It was the prime minister who stabbed me in the back, should I bow down and obey my orders? These words of solidarity should be said to the prime minister, not to teach me a lesson.

Seeing Wei Ba's expression, Deng Zhi sighed and stopped continuing the topic. He turned to Sima Yi outside the city and said, "Ziyu, what can you do to defeat Sima Yi?" ”

Wei Ba shook his head: "The gap in strength is too big, and this person is very shrewd, he won't leave us much chance." ”

Deng Zhi frowned: "You suggest that I abandon the city again?" ”

Wei Ba smiled: "This won't be. Since the general wants to defend it, if he can keep it for one day, he will keep it for one day. I also happened to want to salvage the building ship and a few warships to see if they could be repaired. It's a good thing if it still works. ”

Deng Zhi didn't care much about those ships, as long as Wei Ba didn't let him abandon the city now, he would have no opinion. The two discussed it and estimated the materials stored in the city, but they were still not sure. Now it depends on how long Sima Yi can maintain such an offensive, as long as it exceeds ten days, the supplies in the city will be exhausted, the casualties will increase sharply, and the danger of breaking the city will also increase sharply.

In the final analysis, it is the strength of fighting, and in a situation where both sides are very cautious like this, if you want to win with odds and win more with less, the possibility is very small.

This idea is not only shared by Wei Ba and Deng Zhi, but also by Sima Yi and his son.

Seeing Sima Shi, whose face was calm but somewhat depressed, Sima Yi was a little surprised: "You're back?" ”

Sima Shi lowered his head: "Father, I was ambushed by Wei Ba. ”

"Ambush?" Sima Yi frowned: "Let's listen, how did he ambush you?" ”

Sima Shi recounted what had happened, and then sat there silently, not saying a word. Sima Yi was silent for a moment, and then laughed: "It seems that this kid is really a smart person, and it is beyond my expectation that he can come up with such a solution in a hurry." However, the strange skills are intriguing, and they are not elegant after all. The two countries not only compare the wisdom of the generals of the two sides, but also compare the national strength of the two sides. These little clevers can save a while, but they can't save a lifetime, but I want to see what he can do to make up for the nearly tenfold gap between our two forces. ”

He stared at the silent Sima Shi and sighed softly: "Ziyuan, you disappointed me. ”

Sima Shi bowed down in embarrassment and said, "Yes, the son has disappointed his father, and he is ashamed." ”

"But, do you know what I'm disappointed about?"

Sima Shi blinked and shook his head.

"What disappointed me was not that you were defeated, but that you only saw failure, but you didn't know how to turn it into a lesson. Ziyuan, those who know others are wise, and those who know themselves are clear. You've always been confident, not because you're outstanding — of course, you are great — but because you don't have enough opponents around you, so you don't know yourself exactly right. Well, now you have a haode opponent, which is a great opportunity to sharpen yourself, but weishenme is slumping? If I were you, I would be so happy that I would sing and dance, and I would be drunk. ”

Sima Shi suddenly realized, and his eyes slowly lit up.
