Wang Zheng saw that if the rain fell, he drew east and west between the square inches of the sand table, and explained the entire set of strategic deployments in one breath.

Wang Fei's eyes followed his father's fingers, walking through the mountains and rivers of the sand table, and gradually understood the thoughts of the master of the sand table.

"Turning passivity into initiative, replacing tough battles with sports warfare, and changing tactical disadvantages through strategic adjustment are really subtle!" Wang Fei couldn't help but admire, and while sighing, he rolled his eyes and took the opportunity to ask: "Father, who is the owner of the sand table?" Why was his strategy not adopted? ”

"He is ......" Wang Zhengjian hesitated for a moment before he said slowly: "He is the brother of a certain clan, and he once led the envoys of Longyou, Hexi, Shuofang, and Hedong Wang Zhonghe. Although this strategy is good, it takes a lot of time, and the saint can't afford to wait and doesn't want to wait! What's more, there are people in the political hall who are secretly obstructing, so after all, it can only be on paper. ”

Although he had roughly guessed who the owner of the sand table was, when he heard Wang Zhengjian clearly say the name of Wang Zhonghei, Wang Fei's heart couldn't help but surge with excitement.

In the previous life, when discussing how to capture the stone fort, everyone only admired Wang Zhonghei after the donkey skills were exhausted, "How can the lives of tens of thousands of people be changed to an official!" The noble personality.

After listening to Wang Zhengjian's sand inventory of troops, Wang Fei knew that Wang Zhongsi had already put forward a set of grand strategies that went beyond the stone fort and looked at the old land of Tuyuhun. In this way, not only the dilemma of the stone castle can be easily solved, but also the strategic space of Tibet can be greatly compressed.

The reason why Tibet was able to become a strong enemy of the Tang Dynasty was that the thin air of the Qinghai-Tibet Plateau was its natural barrier against the Tang army. However, there are advantages and disadvantages in everything, and the plateau is easy to defend and difficult to attack, but it is also destined to be sparsely populated and barren. Relying on the material resources of the plateau alone, it is simply impossible to compete with the Tang Dynasty, which has a vast territory and a large population.

The old land of Tuyuhun, in the north of Qinghai Province today, although the altitude is higher than that of Guanzhong and Longyou, there is no great difference, it is suitable for nomadism and farming, and has extremely high military and economic value.

If Tibet gains it, it will be like a tiger with wings and a great victory, the east can threaten Hexi, the north can oppress Longyou, and the west can invade the west; If the Tang army gains it, it will be able to trap Tubo firmly on the plateau, making it a remote and small country that will eventually bow to the Tang Dynasty.

"It's a pity that such a good strategy can't be implemented!" Wang Fei was thinking about the competition between Datang and Tubo on the right line of Longyou, and couldn't help complaining.

"Fei'er, out of this secret room, the matter of the stone castle, you don't have to think about it anymore. Because no matter how much insight and ideas you have, you can't change people's hearts, let alone the stubbornness of the Son of Heaven, the heart of the powerful ministers, and the favor of the border generals. Wang Zhengjian's voice was like a dead leaf trembling in the north wind.

"Then for the sake of the saint's face, let the innocent soldiers fall between the mountains and rocks of Chiling, and turn into a sea of corpses and blood!?" Wang Fei couldn't help but roar like an angry kindergarten teacher.

"I'll find a way to inform Ge Shuhan of this strategy." Wang Zhengjian was not only not annoyed by Wang Fei's confrontation, but his face was a little relieved.

Wang Fei was overjoyed when he heard this, and was about to salute and thank his father, but he heard Wang Zheng say solemnly: "However, don't expect too much. Ge Shuhan seems to be bold, but he is not the same as a certain brother. He put in his early years. It is too late to become famous, so you have to pay extra attention to fame and fortune. Unlike a certain clan brother, he grew up in the deep palace, rarely made a name, and became famous in the world, so he didn't care about things outside his body. Therefore, so-and-so can only do his best and obey the destiny of heaven......"

Wang Fei never mentioned this secret conversation in the dark room to anyone, and he also followed Wang Zhengjian's advice and no longer bothered about the battle of Stone Castle. After all, the traverser is not omnipotent, and the powerful historical inertia cannot be reversed overnight......

Now, in the bright spring breeze on the third day of the first month of March, listening to Wang Yong mention the "mountain attack", Wang Fei immediately recalled the sand table in his father's dark room, and understood that Wang Yong was worried about the upcoming battle of the stone fort.

Regarding the counterweight stone throwing machine and the Greek fire, Wang Fei thought for a while, and said to Wang Yong cautiously: "Uncle Wang Yong, although the counterweight stone cannon is powerful, it is too bulky, not only is it inconvenient to carry, but it is also difficult to use on the mountain trail, I am afraid it will not help to capture the stone fort. As for the fierce oil fire, if it can be thrown into the stone castle city through bed crossbows, etc., it can restrain the Tibetan army. It's just that if you can provide fierce oil fire for the Longyou Army, you still need to ask your father. ”

Although Wang Yong was a little disappointed, he also understood that what Wang Fei said was true. He nodded and said, "I will go to tell Du Hu, and I will also ask Xiao Langjun's Su Ye Juduoduo to make a unique weapon to restrain Tibet!" ”

"Restrain Tibet?" Wang Yong's words made Wang Fei suddenly remember some information he had seen in his previous life, so he asked tentatively: "Uncle Wang Yong, have you ever fought with the Tubo people?" ”

"Is this ...... I have exchanged hands two or three times. Wang Yong hesitated for a moment before hesitantly replying.

"Is the armor of the Tibetan warriors woven from many small iron rings?" Wang Fei gestured with his hands to the appearance of chain mail.

Seeing that Wang Fei didn't care when and where he fought with the Tubo people, Wang Yong breathed a sigh of relief in his heart, and then replied with a smile: "Xiao Langjun is talking about chain mail, right?" The ordinary soldiers in the Tibetan army wore cowhide armor, and only the general's personal guards, armored cavalry, and middle and senior officers could wear chain mail. However, the guards of the stone fort are all elite soldiers of Tibet, and it is very likely that everyone has chain mail. ”

"Uncle Wang Yong, how protective is the chain mail?"

"Hmm......" Wang Yong pondered for a while before he replied clearly: "The chain mail is still inferior to our Datang's Mingguang armor, but its protective knife splitting sword is very effective, and it is difficult for ordinary bows and arrows to break armor at long distances." Xiao Langjun, could it be that you have gained from breaking chain mail? ”

"Uncle Wang Yong, I just vaguely thought about a few points, which may not be applicable, and please help me discern them." Wang Fei replied solemnly.

"Xiao Langjun, please speak!" Wang Yong's eyes were full of expectation.

"The foundation of chain mail protection lies in the rapid dispersion of blows received in one place through interlocking metal rings, so that the damage of the sword can be effectively reduced. At the same time, the diameter of the metal ring is very small, the weaving is fine, and the general cluster of arrows is larger than the ring diameter, so unless fired at close range, it is difficult to penetrate the metal ring from a long distance. Uncle Wang Yong, I don't know if what I said is in line with the truth. Wang Fei used the most popular language, trying his best to avoid using physics words such as "pressure", "area", and "pressure", to roughly describe the defensive principle of chain mail.

"What Xiao Langjun said is very true! The horizontal knife slashed on the chain mail of the Tibetan army, often only lightly injured but not severely injured; Bows and arrows are basically useless when they shoot from a distance; Only when charging with a lance, you can rely on the speed of the horse and use the lance to forcibly break the armor. Wang Yong recalled the battle formations he had experienced in the past and nodded yes.

"To put it in such detail, I should have fought more than two or three times with the Tubo army, right?" Wang Fei was suspicious in his heart, but he still analyzed the chain mail in his mouth: "Uncle Wang Yong, from the characteristics of the chain mail, we can deduce that there are three ways to break the armor. The first is what you just said, increase your speed and use a sharp horse lance to break through armor at close range; The second is to use blunt weapons such as giant axes and hammers, relying on the weight of the weapon, to vigorously break the armor; The third is to pierce armor with a bow and arrow......"

"The stone fort is located on the top of the Red Ridge, the cavalry cannot be used, and the horse lance is naturally useless; Blunt weapons can be tried, but they must be used in close combat, and they are not very useful for capturing stone forts. It would naturally be best if the bow and arrow could break the armor, but, Xiao Langjun, didn't you say that the bow and arrow could only break the armor at close range? Before Wang Fei finished speaking, Wang Yong was anxious to compare the advantages and disadvantages of his armor-breaking method.

Facing Wang Yong's question, Wang Fei smiled and said: "Ordinary arrows will definitely not be able to break armor at a long distance, but special bows and arrows can. ”

"Special?" Wang Yong was very curious.

"Uncle Wang Yong, the chain mail protects the feather arrows with the fineness of the iron ring, but no matter how small the iron ring is, there is still a gap. If you can create a batch of feather arrows as thin as long needles, you can easily penetrate the protection of chain mail and kill them from a distance! ”

"As thin as a long needle?" Wang Yong gestured with his hand, simulated the shape of the arrow, and said eagerly: "Xiao Langjun, your method is amazing!" If such a sharp weapon can be created, the chain mail of the Tibetan people is not as good as leather armor! I just don't know if I can build it? Also, is it enough to leave it to Longyou? ”

"Uncle Wang Yong, whether this arrow can be made, you have to ask Zhao Dazhui. However, I don't think it's too difficult, because it's just a small change from the existing process, not a redesign. After getting Zhao Dazhui's affirmation, I will draw the drawings as soon as possible, and you will find a way to hand them over to Longyou. As for the time, if the Longyou Army gathers the craftsmen of the army, the government, and the people and makes every effort to build it, it should be in time. ”

Hearing Wang Fei say so surely, Wang Yong's heart also calmed down. He knew that although Xiao Langjun was young, he was by no means a person who opened his mouth. After returning from Shattered Leaf City, there are even more amazing moves.

"With the help of this arrow, the capture of the stone fort is a little more certain! A representative of Longyou's old friends thanked Xiao Langjun for his kindness! Wang Yong said solemnly: "I just don't know what the name of this arrow is?" ”

"If the heavy armor pierces the girl's ear, why not call it the 'ear-piercing arrow'!" Wang Fei respected the historical name of this divine weapon, and did not choose to name it himself.

"Uncle Wang Yong, although the ear-piercing arrow can restrain the chain mail of the Tubo people, it still can't reverse the geographical advantage of the defenders of the stone fort. If the stone fort is stormed, the piercing arrow can reduce some casualties of the Longyou Tang army, but I am afraid that it will not still be able to achieve the most satisfactory results. Actually, it would be nice if you could avoid storming the stone fort. Wang Fei remembered Wang Zhonghe's strategy and couldn't help but say more.

Wang Yong was not surprised by Wang Fei's words, he continued Wang Fei's words and said: "I also know that piercing the ear arrow cannot completely reverse the overall situation. It's just that if you give up the strategy of storming the stone castle and attacking in a roundabout way from east to west, Geshu Jieshuai may not be able to listen to it. A certain ...... A certain old friend is soft-spoken, and it is estimated that it is difficult to change anything. ”
