In order to prevent the Song army in this era from having a wasted hand-to-hand combat like the Qing army after entering the gate of firearms, Sun Hui deliberately strengthened the melee training of the firearms unit while increasing the number of cold weapon troops, so that every gunner and firearm soldier could skillfully use their own self-defense cold weapons. Of course, as a successful behind-the-scenes manipulator, he gave all this credit and reputation to Jia Nidao.

When the drill ended, Sun Hui looked at Gundam and found that the former arrogant and arrogant general had a look of shock in his eyes.

"Gao Taibao, do you think this 'Mountain Splitting Army' can do anything?" Jia asked Gundam with a smile.

"Such a sharp firearm does have the ability to split mountains." Cold sweat trickled down Gundam's forehead.

"Then I'll hand over my 'Mountain Splitting Army' to you," Jia Rudao looked at Gundam and said, "plus the elite soldiers you recruited, 60,000 people, it should be no problem to ambush Jiaozhi, right?" ”

"The last general is willing to collect all the land of Jiaozhi for my Great Song Dynasty and get rid of the troubles of southern Xinjiang forever!" Gao Gao said in a deep voice and bowed deeply to Jia Rudao.

"Okay, I should return in triumph as a prince and a general." Jia Rudao nodded, but his quiet words shocked Gundam's body.

Among the Gundam's guards, Dong Jinhong, who was dressed in bright armor, couldn't help but pout in disapproval when he saw Gundam's appearance.

At the end of the exercise, Gao Hu returned to his yazhong, and not long after he sat down to rest, someone came to report that Yue Lun, the commander of the Ma Bu Army, had come to visit.

As soon as he heard that Yue Lun was coming, Gao Hu's face was overjoyed, "Hurry up, please." ”

Yue Lun is a direct descendant of Yue Fei, strong in martial arts, when Jia Rudao aided Xiang, he was a general in the reinforcements, and during the Xiangyang War, he was famous for cutting the Yuan army general Ali Hague, and was promoted to the commander of the forbidden army, and Gao Hu hit it off at first sight, the two often talked about armaments together, and Yue Lun also led the army to participate in the southern expedition, and was one of the main generals of the escort force of the "Splitting Mountain Army".

"Lao Yue came just in time, take a look at what I wrote, if there are any omissions, help me polish it again." Seeing Yue Lun come in, Gao Hu suddenly remembered something and took out a manuscript to show Yue Lun.

"It is recommended that the army be uniformly equipped with Bohai bows and Bohai heavy arrows?" Yue Lun was taken aback.

"Yes. According to our Great Song Dynasty military system, the army is equipped with a long tip angle bow, the length of the foot archery bow is 4 feet 7 inches after the winding, the bow power has seven, eight, nine buckets and three (about 70-90 pounds), the length of the riding bow is 4 feet 2 inches, and the bow power has six, seven, and eight buckets (about 60-80 pounds), and in actual combat, in order to be able to break the armor and kill the enemy with the maximum range, the infantry and cavalry bows are mainly equipped with first-class bows, whether they are foot bows or riding bows, the total length of the arrows is two feet seven inches (about 85 cm), and the weight ranges from nine to fifteen coins (about 45 grams- 75 grams), with 2 feet 5 inches (about 75 centimeters) as the drawing distance for the full bow. Although the rate of fire can be guaranteed, the range is taken into account. However, with this light arrow to supplement the strong bow, the light arrow can absorb a limited amount of bow power, not only can not use the power of the strong bow to break the armor and injure the enemy, but makes the excess bow power directly act on the bow itself, causing loss. ”

Gao Hu only smiled after hearing Yue Lun's words, so he walked to the weapon rack and took down two horn bows, one was the long-tip horn bow commonly used by the Song army, and the other was the Bohai bow commonly used by Gao Hu himself. The text on the tips of the two bows indicates that they are both bows with a tensile strength of nine buckets, but in front of the Bohai bow with a total length of five feet and two inches, the four-foot-seven inch Song Army's long-tip horn bow inevitably looks a little more delicate.

Yue Lun used the Song army's long tip horn bow and Bohai bow respectively, with two armor-piercing arrows weighing about 15 yuan and two two-foot-seven inch armor-piercing arrows weighing about 15 yuan and two Bohai armor-piercing heavy arrows weighing 20 yuan, respectively, to shoot at a human-shaped pine target 30 steps away and 3 inches thick. When the larger Bohai Cape Bow shoots the 15 Yuan Song Army's armor-piercing war arrows, the difference between the target depth after hitting the target and the arrows shot by the Song Long Tip Horn Bow is not obvious, but when the two are replaced with Bohai Armor-Piercing Heavy Arrows, the advantages of the bow design of the Bohai Cape Bow are immediately revealed: due to the growth of the bow body, the full bow pulling distance of the Bohai Bow can reach three feet, Yue Lun found that when he pulled the Bohai Cape Bow to a drawing distance of about two feet five inches and then back until the bow was full, the pulling feeling not only did not appear stiff, but was quite soft, This is the labor-saving effect brought about by the leverage effect of the Bohai bow reverse warping and large long tip. Coupled with the three-foot big tug-of-war, the heavy arrow was given a longer working distance, and the result was that when shooting an armor-piercing heavy arrow of 20 yuan, the arrow shot by the Bohai bow penetrated the target depth by 3 inches more than that shot by the Song army's long-tip angle bow!

"Under the same bow force, even in the face of armored targets, in a dozen steps to shoot heavy arrows, the arrow armor-piercing effect of the Bohai bow is stronger than the current army equipped with a long angle bow, the Bohai bow bow on the bow pad, can well buffer the bow string damage to the bow arm when rebounding, even if the string pad is damaged, it is not difficult to repair and replace." As Gao Hu spoke, he took out a piece of music from his arms and handed it to Yue Lun.

"As soon as you go up to this "Coordinating the Bow and Arrow Discussion", I am afraid that those officials in the court will give you a big hat of "changing summer with Yiyi". Yue Lun shook his head and smiled bitterly after reading the note handed to him by Gao Hu.

"Those sour and rotten literati who are powerless, how can they know about the armament in the army? Aren't the Divine Arm Bow and Cold Forging Foot Armor installed in my Great Song Army also imported from Western Xia and Qingtang Qiang? Gao Hu said angrily: "Now the various bed crossbows equipped in my Great Song Army can control the enemy three to five hundred steps, and the crossbowmen equipped with the Divine Arm Bow and the Enemy Defeat Bow can also control the enemy by 200 steps. In this case, there is no need to ask the archers to shoot hundreds of paces from a distance, I think the archers only need to defeat the enemy at a distance of thirty or fifty paces. I dare to conclude that the Bohai Bow, which is powerful and comfortable to pull, and is convenient for shooting for a long time, will definitely be favored by the soldiers after it is popularized. ”

"This Bohai bow is easy to use, but if you go to the book now, I'm afraid that you won't be able to catch up with this battle of the southern expedition." Yue Lun said, "The whole army is replaced, how can it be so fast, even if Lord Pingzhang agrees, it will not be possible to complete the matter within a few months." ”

"It's okay to equip the Southern Expeditionary Army first." Gao Hu said a little anxiously, he also participated in today's "Nine Into Ten Chains" exercise, and he was not satisfied with the performance of the archers from a professional point of view.

"Don't worry, you can change your direct guards first, a few hundred can be, this southern expedition is very important, if you have a bright performance, you will go to the book again after you come back, and this matter will be done." Yue Lun said, "There must be fewer gossips." ”
