It was discussed that at this time in October, the cold current had swept the land of the north, and the snowflakes were flying. The rivers and lakes in the north of Hengshan were all frozen and hard. The large quantities of materials were transferred before the year, and it was too late to reach the city walls in Yucheng ridge.


    At this time, the front of demon man has appeared in the front line of yuchengling and will soon attack the South on a large scale; There are five or six thousand elite riders in Longxiang camp. Led by Le Yi, they are still stranded at the West foot of zhanmaling and can''t come over for the time being.


    The appropriate plan is to wait until the spring of next year. Although the flood will wash the low-lying plain north of Hengshan into mud and swamps that devour people and animals, Longxiang camp will have three wind flame airships to transport people, horses and materials, and build a solid city fortress in yuchengling before the winter of next year, There should be no problem at all.


    In addition, the new crossbow chamber structure is not only suitable for individual combat crossbow, but also suitable for Tianji crossbow.


    Although the core arrow box has not changed much, Chen Hai and his colleagues decided to name the new war crossbow bore crossbow, so that it can be distinguished from the old arrow box crossbow.


    At present, the transformation of the 30 old Tianji crossbows incorporated into Longxiang Daying is quite troublesome. In the next year, 30 new Tianji heavy bore crossbows should be built and these old crossbows should be replaced one after another.


    Before the Tianji heavy bore crossbow was officially launched, the old style crossbow was still a sharp weapon for the families of various sects.


    For Tianji heavy bore crossbow, it is necessary to ensure that each crossbow bullet can drill through and tear open one-third of an inch thick gold-plated iron plate beyond the range of 2000 steps. The Heavy Crossbow bullet with three inch length and cluster front bullet tip structure, especially the cluster front bullet tip, will be cast with eight grade gold-plated iron.


    Even so, the consumption of gold and iron for each Heavy Crossbow is still only one-fifth of that of the traditional heavy crossbow.


    If the replacement can be completed within one year and the old heavy crossbows and arrows stored in Longxiang camp can be replaced with heavy crossbows, the continuous combat time of Huwei camp will be increased by five times, which will be extremely terrible for the improvement of combat potential.


    Although the closed crossbow chamber structure will bring a series of problems such as overheating, and the structure and operation will become more complex. The crossbow chamber components need more advanced quenched iron casting, but weighing it down, it is also a great progress.


    In addition, if the enemy only wins in a large number and the defense of individual soldiers is limited, the heavy loaded crossbow will be replaced with a cheaper ordinary crossbow that day


    At this time, the single armed crossbow can really expand the scale of mass manufacturing.


    Tianji academy has long established a workshop to manufacture individual combat crossbows. Although the cost is not low, and it is not suitable for mass equipping Longxiang camp, the performance of the old individual combat crossbow is still much better than the traditional crossbow. There are many clans of Zong valve in Yanzhou, such as crucian carp crossing the river. More than 1000 individual combat crossbows built by Tianji Academy in two years have been robbed by high prices, As a result, Chen Hai was equipped with less than 200 individual crossbows at Huwei camp.


    At present, the war crossbow factory directly changes to a new type of single armed crossbow, and the annual output should reach 1000.


    After all, the arrow box array and rune array needed for the single soldier crossbow are simplified, and ordinary craftsmen and apprentices in Tianji academy can begin to refine them. At present, the Tianji academy has released the main mechanism puppet skills as an apprentice of a craftsman. The only requirement is to turn in the refined standard Rune array components regularly. In fact, this is the main means for many workshops affiliated to Tianji academy to break through the production bottleneck.


    However, even so, if it is the most successful, Longxiang camp will have the most elite 1000 soldiers in Huwei camp next year, who can complete the dressing change. From the first to the fifth battalions, it will take at least five years for 30000 soldiers to complete the initial dressing up. This time seems very slow, but you can know how terrible this speed is when you know that after the dressing up of Longxiang camp will be comparable to the combat power of Hexi Dao yamen soldiers.


    Su Yuan and sun Gan are still worried about building a city in yuchengling next year and finally guarding against the onslaught of demons and barbarians. In their opinion, with the current speed of dressing and preparation, they should be more fully prepared in three years. Considering the construction of yuchengling City, they should be more confident.


    Zhang Xiong, sun Gan and Su Yuan got the secret map of the new bore crossbow and went down to prepare for it. Huang Shuang also stayed with Chen Hai on the tower and couldn''t help asking, "is this the inheritance of the hidden pulse?"


    Chen Hai was stunned for a moment and realized that Huang Shuang meant a group of puppet weapons with the same tradition of refining weapons as Yanzhou, such as bore crossbow. He also didn''t know how to answer Huang Shuang.


    Strictly speaking, the civilization system accumulated by the earth after countless years of development should naturally be regarded as a kind of inheritance.


    The earth civilization seems to be based on the application of external energy and machinery such as gunpowder and electricity, while the inheritance civilization of Jinyan Zhuzhou is based on Xuanfa and rune array. However, in Chen Hai''s view, the most fundamental difference between the inheritance of the two civilizations is that the earth civilization is based on civilian society, and the inheritance of Jinyan Zhuzhou is based on a small group of elite xuanxiu standing above all living beings, Regard the general public as ants.


    The same is true of the traditional clan door and clan valve in Jinyan Zhuzhou. They are more obsessed with making extremely fine and complex high-level magic weapons or high-level large arrays. The more advanced magic weapons and large arrays, the more advanced xuanxiu and martial arts are required to master; At the same time, it ensures that the pyramid ruling structure inside the sect door and sect valve can be stably inherited.


    Purely from the technical level, the metaphysical inheritance of Jinyan Zhuzong is not necessarily higher than the earth.


    Except for the legendary Wei Boyang, none of the tianbang figures in Yanzhou''s history can exceed 800 years old. In addition to this, the tianbang characters in Yanzhou still have a screen neck that can''t be broken through, not to mention the physical body flying. Even the surviving flying magic weapon has an insurmountable limit in speed.


    This speed limit bottleneck, studied by Chen Hai, is the speed of sound.


    Chen Hai''s speed of chopping with his halberd at this time naturally broke through the sound speed long ago, but the extreme speed of the body moving and galloping can reach a frightening one hundred meters in a short time, but only less than one-third of the sound speed.


    This is also related to Chen Hai''s ability to quench his body with wind and thunder Gang after he understood the true meaning of wind and thunder. In the later stage of Mingqiao territory and even the martial cultivation of daodan territory, even if his feet can burst out such strong strength, the muscles, bones and veins of his body can hardly bear such a huge force.


    After all, this is totally different from moving in a high-speed plane.


    However, the earth has long broken through the speed of sound at the technical level.


    At this time, Chen Hai founded the Tianji learning palace in the depths of Qin Tongshan. It seems that he developed organ puppet art based on the prohibition of Rune array, but the change of thinking mode is subversive.


    Tianji school palace has built Tianji heavy bore crossbow and single soldier bore crossbow, which can be controlled by ant people. After being controlled, it can directly threaten the lives of senior xuanxiu strongmen. In fact, it is a forced reversal of the old style inheritance of Jinyan states from a small group of elite xuanxiu to civilian society.


    This was originally a great reactionary and toppling, but due to the chaos in Yanzhou, the control of the imperial valve in Jingjun led by Ying family has been weakened by the chief officer, and many powerful vassal forces in border counties are eager to enhance their own strength. The cultivation of elite xuanxiu is too slow to fill the consumption of large-scale war. The Tianji heavy bore crossbow, single bore and short-term training can be qualified ordinary soldiers, They didn''t suffer any resistance and were accepted by the patriarchal clan in Yanzhou.


    At this time, there may be some old stubborn people who regard Tianji school as a place for deviance, but if these people are stubborn, the only end is to be swallowed up by other forces.


    Compared with the past tradition of preaching Dharma and supporting religious valves in Yanzhou, what Chen Hai did at this time can be said to be another subversive new model, which may be called hidden vein inheritance.


    However, Chen Hai is not complacent because he knows that there is a powerful inheritance of higher and more terrible, which can even make people immortal, directly control the laws of heaven and earth, and can really be called gods and demons.


    This inheritance is neither arrogant nor out of reach.


    The temple, the Dragon Emperor cangyu and Zuo Er, the source of the inheritance of the Taoist temple, come from this kind of strong inheritance.


    The Luocha region at the other end of the blood cloud wasteland also exists at a much higher level than the Jinyan states.


    As a result, some strong lives in Luocha region are even suppressed by the laws of heaven and earth. Even if the blood cloud wasteland is completely connected with Luocha region and Jinyan States, these strong lives cannot enter Jinyan states.


    What is the existence of Luocha domain?


    Where did the temple come from, why did it fall in the blood cloud wasteland, and why did it assume the responsibility of educating Jinyan States and resisting the invasion of Jinyan states by blood demons?


    Does he have a chance to return to the earth in this life?


    These are the most fundamental problems tangled in Chen Hai''s mind. Chen Hai even suspects that the temple also comes from Luocha domain, and Luocha domain is more vast and vast than left ear said. Luocha blood demon is only one of the forces in Luocha domain.


    But all this is just Chen Hai''s guess, and I don''t know if I have the opportunity to step into the Luocha domain in this life.


    Chen Hai temporarily suppressed these thoughts that he could not completely get rid of. At the time of doing business, he still did everything possible to strengthen the defense of the seven defensive strongholds on the east line with Hengshan city as the core, together with Huang Shuang, Wu Meng, Zhou Jun and other generals.


    In the short term, as far as the melee defense of the stronghold is concerned, there is no better and more convenient weapon than the counterweight catapult crossbow - Su Yuan and Zhang Xiong sent over 100 light catapult crossbow accessories this time. However, the base of the catapult crossbow and the crossbow rod made by cutting down Millennium hardwood need to be made by mining raw materials in Hengshan city.


    Fortunately, when Tianshui County soldiers withdrew and handed Hengshan and other cities over to Longxiang camp for defense, more than 50000 auxiliary soldiers and Minyong stayed and were taken over by Longxiang camp. Otherwise, it would not be difficult to cut down hundreds of Millennium solid trees years ago, but it would not be easy to mine stones and reserve a large number of stone bullets.
