Because of the musket troops' continuous killing and wounding of strong orcs, it was never possible to gather too many strong orcs in front of the city wall of the Holy Helmet Valley, and even a few cloud ladders could not be erected, and Li Xiaoyi didn't care what Chu Xuan's plan was, he arranged for someone to block the sewers on the city wall of the Holy Helmet Valley early in the morning.

I really don't know how Zheng Zhe's head grows, using the Undead Bible to change the terrain not to mention blocking the sewers, but actually changing the terrain inside the city wall, saying that it is enough to prevent the strong orcs from attacking the city wall, do you not blow up the uncomfortable sky, or don't break it and be unhappy Smecta? Besides, if you're going to blow up the walls, then you should arrange a killing position behind the walls and erect another wall inside?

It wasn't until more than an hour later that the orcs finally pushed the siege machine closer to the city walls. However, among them, only the stupid and clumsy siege vehicles can provide some cover for the strong orcs, and other siege equipment, such as siege towers, except for the huge wooden main structure, covered with planks and fur that can defend against arrows, are useless in the face of bullets, of course, if the strong orcs know some knowledge of external ballistics, they can resist bullets by covering the thick cotton quilt with water and thickening the planks, but unfortunately they don't know.

As for catapults and ballistas, while rifle bullets can't destroy them, they can effectively kill and injure operators, and muskets have a much longer range than these big guys! As wave after wave of operators were killed and wounded under the concentrated fire of the rifles, these instruments soon lost their effectiveness, but there were too many strong orcs, and even under the continuous resistance of rifle fire, as time went by, more and more strong orcs still gathered under the city walls, and more and more ladders were erected.

Especially compared to ordinary humans, the physical fitness of strong orcs is too strong, but melee combat is first-class powerful, it takes two humans or an elf to resist a strong orc, so as long as there is a strong orc on the city wall, it can contain the defenders of a large area, and the members of the Middle-earth team and several plot characters such as Yaragon can be cleaned up, at this time, it is Zhao Yingkong's highest efficiency, she does not need to move on the city wall at all, she can directly flash to the vicinity of various cloud ladders to fight, It's faster than Zheng Zhe riding a skeleton horse back and forth.

But after all, there are too many strong orcs, and after a long battle, the walls of the Holy Helmet Valley have also exposed a shortcoming, that is, they are too narrow.

The Valley of the Holy Helmet lies on top of the city wall between the valleys, and at the same time, only three rows of soldiers can stand side by side, which is more than a meter wide, and there is no room for maneuver at all, especially if the slightest enemy climbs it, the entire wall can be cut off! You must know that the width of the top of the Great Wall is about 4.5 meters on average, which can not only quickly mobilize personnel to move, but also lay large equipment on it.

In addition, the city wall is more than ten meters high, there are only steps at both ends to go up and down, and the steps are basically only two people side by side width, I really don't know what I thought when I first built the city wall, if this is a tug-of-war, just shift eating can block the city wall!

"Zheng Zha, don't run back and forth to cut people, just cut all the ladders, remember to cut them from the middle!"

Watching Zheng Zha jump into the pile of strong orcs from time to time and slash and kill, and then run back on a skeleton horse, Li Xiaoyi could only shout to Zheng Zha helplessly, this stupid man, you cut all the ladders, can the strong orcs still stack Arhats and climb the city wall?

With the support of the musket troops, and the city wall was not blown up, the Holy Helmet Valley easily lasted until the next morning, and finally Li Xiaoyi's worries did not come true, and the dried tofu brought the Rohan cavalry to the battlefield smoothly, and after a rush to kill, the battle ended smoothly.

But to be honest, Li Xiaoyi really couldn't understand how the strong orcs were defeated, because even after a night of fighting, the strong orcs still had at least half of their troops, seven or eight thousand, and the cavalry brought over by Dried Tofu was only one thousand and five hundred in total, a difference of four or five times!

According to the famous Lanchester battle model, the military strength of both sides in a battle is directly proportional to the square of the combat strength of their respective armies, and to take the simplest example, if two armies of equal strength come together, both sides will eventually be destroyed.

But if an army goes to battle with an army that is twice as numerous as it, but the strength of each soldier is only half of his strength, since the opponent's number is twice as large as theirs, the initial force index is 4 times that of the opponent, although the combat strength of this army is twice that of the opponent, but in the battle, the rate of attrition of its troops is twice that of the opponent, and the final winner will be the side with more people, although their individual combat strength is only half that of the opponent!

Based on this calculation, when the difference in strength is four to five times, the combat effectiveness of a single soldier must be 16 times or even 25 times that of the opponent, and Bruce Lee only dares to say that one fights eight! And even if this combat effectiveness data is calculated, it can only guarantee that they will fight together, but in fact, the Rohan cavalry has cut down the strong orcs, and almost no one has died! ……

To give an intuitive example, in "Smiling Proud Jianghu", Dongfang Undefeated singled out Ling Hu Chong, Let Me Go, Xiang Wentian, and Ren Yingying in Heimu Cliff, no matter what the result is, but at least Dongfang Undefeated was not crushed by the other party, basically it can be regarded as the same combat effectiveness of both sides, in this case, Dongfang Undefeated One person's combat power is 16 times the average combat power of the other four people! Fortunately, Dongfang Undefeated only learned the Sunflower Treasure Book, not mathematics, otherwise, I am afraid that "Smiling Proud Jianghu" will be over......

And also through the example of the undefeated in the East, you can also see the shortcomings of the strategy of elite soldiers, afraid of the dead! For example, although Dongfang is undefeated and can beat the average size of 16 Linghu Chong armed groups, as long as he is injured, he will be considered a loss.

In the film, although the strong orcs fought all night, the total loss of troops was less, at most no more than three thousand, that is, there were 12,000 people left, in this case, the ratio of troops between the two sides reached one to eight, in that case, the individual combat effectiveness of the Rohan cavalry would be 64 times that of the strong orcs!

What kind of "tough" strong orc is this! What about two humans or an elf to stand up to a strong orc? Correspondingly, what a terrible Rohan cavalry!

According to this data, when I went to the battle of Minas Tirith, the capital of Gondor, the country of Rohan sent out 6,000 cavalry, and they were still dealing with half-orcs whose combat effectiveness was half worse than that of the strong orcs, which should be able to deal with 113,000 people, but in fact, in Minas Tirith, the total number of Sauron's army was only 45,000......
