With Murong Nan's roar, the lance in his hand slammed into a pine tree in front of him, this pine tree was two zhang high, at least two people had to join hands to enclose it, it was so tall and stout, even the best lumberjack had to cut and saw with an axe, and he was busy for more than a moment before he could put it down.

But Murong Nan's impact, but it was like with the strength of ten thousand jun, rushed up to the big tree, only to hear the sound of "Karala", the big tree was pierced by this long lance, fiercely pierced, and with the rapid shaking of Murong Nan's wrist, a turn, the entire tree body, suddenly a long crack horizontally, constantly expanding, when Murong Nan and the people and horses rushed over the big tree more than ten steps, this crack finally made the whole big tree, crashed down, and also knocked down a small tree more than six feet high behind, smoke and dust, Startled the flocks of birds in the forest.

Murong Nan's hand was empty, he gave up the riding lance in his hand when he sprinted to the big tree, and the last wrist shook, only to drill such a big hole, directly using this huge momentum, the inside of the pine tree was shattered, so that it toppled, Liu Yu glanced at the broken part of the big pine tree, and the smooth and complete section when it was sawed down, this time the broken place has been stirred up into a piece of erosion, as if something is exploding inside, you can imagine how huge the impact is.

Liu Yu sighed: "I can't imagine that your riding lance assault is so powerful, such a big tree, it is actually interrupted by one blow, if it is on the battlefield, I am afraid that more than ten columns of formations will also give you such a rush, the first two or three rows of people will definitely die, even the companions behind will also suffer internal injuries." You said that it was difficult for the infantry formation to withstand such a cavalry assault, and I believe it now. ”

Murong Nan nodded triumphantly: "You still have a clear understanding of the situation, I know, you Jin people think that the infantry formation is unbreakable, but in fact, you have lost to the cavalry again and again on the plain, and more than half of them are head-on, Liu Yu, you must have a clear understanding that the cavalry that can hold such a strong assault on the horse is not the Hun light cavalry that can only ride and shoot, they have a strong impact, ignoring this point will only pay the price of blood on the battlefield!" ”

Liu Yuzheng saluted: "Thank you for your advice." But I still have one more question, if our lance assaults with such power, it will inevitably break, but look at the lance you just now, it's still good to pierce the tree, how is this possible?! ”

Murong Nan smiled and looked at the riding lance scattered on the side: "You have been curious about this riding lance of mine for a long time, Liu Yu, you can go and see this lance yourself, and you will know why." ”

Liu Yu nodded, rode a few steps forward, picked up this long lance from the ground, and his face changed as soon as he started it, because it was different from ordinary lances, this lance felt a lot lighter when he got it in his hand, not like solid wood, but felt like it was made of bamboo.

Liu Yu was surprised: "Could it be that this lance is made of bamboo?" ”

Murong Nan followed and shook his head: "No, it's not bamboo, although the toughness of bamboo is strong, but the hardness is insufficient, we use it as the best material for horse lance, and we are the first to push the thousand-year-old Tuomu of Xianbei Mountain in Beida." ”

"Tuomu was born in the bitter cold land of the ice and snow, the hardness and toughness are excellent, it is a good material for our Hu people to make a lance and a bow, in fact, you Han people also use Tuomu to make a bow, you know, a strong bow of more than four stones, what is needed is not only hard, but also tough, often made of Tuomu or sandalwood, and the same reason as using this horse lance."

Liu Yu nodded and stroked the mallet: "But the hardwood bow is far stronger than this riding lance, but I am afraid that under a blow, it will still break in the middle, how can you be so flexible?" ”

Murong Nan said with a smile: "This is the method of making horse lance, we have to first soak this thousand-year-old tree in oil and soak it repeatedly, so that it is no longer deformed or cracked, and then it is the first step." ”

"The oil immersion process often takes a year, and then the sticks are taken out and left in a shaded area to dry, which takes several months. Then continue to soak in oil, and after a year, take it out and dry it again, and so on three to five times, that is, it will take eight to ten years to make the branches. ”

"With three or five of these branches, put together, and smeared with glue on the outside, you can make such a lance ranging from four feet to eight feet, and wrap hemp rope on the outside, paint it, wrap it in kudzu cloth, layer by layer, and each layer of raw lacquer is dry, and then wrap it in another layer of kudzu cloth, and so wrap it in four or five layers, until it is cut with a sharp knife, and it can make the sound of gold and iron, just like this!"

As he spoke, he took out a saber from the saddle and went up to the lance in Liu Yu's hand, only to hear a "ding" sound, sparks on the lance, and the sound of gold and iron hitting shook Liu Yu's eardrums, and the long lance in his hand also felt that it was vibrating violently.

But the lance in his hand now is shaking slightly, but there is not even a piece of paint on the lance, he took advantage of the situation to wave it twice, everything is as usual, Liu Yu sighed: "I have heard of the people of the Southern Barbarians, there is such a complicated process for making rattan armor, I can't imagine that you northern Hu people, making this kind of horse lance, can actually be so exquisite, I can be regarded as an eye-opener." Could it be that such a riding lance has the high strength of an assault and can penetrate a tree, and has this soft toughness, so as not to knock the knight on the horse backwards? ”

Murong Nan nodded: "Yes, but no matter how hard this lance is, it is hard after all, and the moment of sprinting, it may not knock the rider out, but if you keep holding it still, the power of the stirrup will not be able to hold it, so when I break through the formation, just like the one just now, I shake my wrist and turn it, let the lance rotate, and after reaching the maximum impact, I must let go decisively, only in this way can I ensure that you are always on the horse." ”

Liu Yu looked at Murong Nan's body, and saw that his originally tightly wrapped right shoulder armor, the three cowhide belts, had been broken two, and even the appearance of the shoulder armor was a little deformed, which showed how powerful the impact force was this time, Liu Yu sighed: "Rushing into battle like this, it is indeed killing ten rows of enemies, self-injuring your shoulders and arms, no wonder your right shoulder armor is wrapped so tightly than your left shoulder, it turns out that this is for this." But ............"

Liu Yu's eyes flashed coldly: "After you break through the formation like this, you must abandon the lance and be in the enemy formation with your bare hands, how can you live?" ”
