However, in doing so, although the driving force of each Shenji chariot can be increased by 50%, the complexity of manufacturing and control has to be increased several times, and the increase of driving force by 50% is still far from meeting the needs of intermediate Shenji chariots.


    The body structure and armor of the intermediate Shenji chariot are fully strengthened, the weight should be increased by at least three or four times, and the speed should be increased by one third, which means that the driving force should be increased by at least seven or eight times, rather than 70 or 80%.


    Chen Hai thought for a long time. The only possibility is to completely improve the internal structure of the wind array box.


    There are two kinds of Rune array prohibitions in the world. One needs true element mana after sacrifice and refining, which accounts for the vast majority of the existing Rune array prohibitions; There is another kind that does not need sacrificial refining and can operate by itself once refined. This kind of Rune array prohibition is very few, but it is the real basis for the existence of mechanism puppet art.


    Chen Hai calls the latter kind of talisman array forbidden system Tianji forbidden system. The number is so rare. It is not difficult to imagine how difficult it is to innovate a new Tianji forbidden system on the basis of the existing Tianji forbidden system.


    On his way back from Lucheng East, Chen Hai thought hard about this problem for several months. He also participated in some ideas put forward by the craftsman''s Association. Finally, he felt that the integration of Yufeng Rune array and Jiyan Rune array or Yufeng Rune array and space Rune array might create a new Tianji prohibition he needed.


    The most basic Rune array itself is composed of a variety of Tao and seal characters. The wind Rune array, flame gathering Rune array and space Rune array are composite runes. The three runes should be disassembled, reassembled and combined to form a new two-level composite Rune array. The calculation work is so complex that it will collapse.


    Even those who are strong in adverse circumstances may not be able to create a new composite Rune array in their lifetime. Some people are patient and have been closed for more than ten years or even decades, just to deduce a new composite Rune array.


    Chen Hai set up a seminar to disassemble the rune array, list all possible combinations and give them to the following craftsmen for verification.


    Moreover, on his way back to the East, Chen Hai has figured out all possible organizations of the new composite Rune array. At this time, a large number of tool refiners and puppet craftsmen who are good at daozhuan and rune array are needed to help verify them one by one.


    Otherwise, Chen Hai will verify all five or six hundred possibilities, and he won''t want to do anything else in his life.


    All craftsmen in the spirit setting have the ability to deduce simple Rune arrays. Hundreds of craftsmen in the spirit setting have devoted all their energy and enthusiasm to the study of heaven''s secrets and prohibitions. Each of them is allocated three or five apprentices as assistants. The efficiency may not be hundreds of times faster than that of Chen Hai alone, but they can still do it thirty or forty times faster.


    However, if Chen Hai wants to do this, he needs to gather the tool refiners and puppet craftsmen in the workshop to completely break the door restrictions.


    However, to do this, the resources consumed are extremely terrible.


    Hundreds of puppet craftsmen and more than 400 craftsmen and apprentices have to provide for monthly silver every month; In addition, five or six hundred kinds may have to be verified. If they go well, they also need to consume up to one or two thousand pieces of dark yellow middle and lower grade magic weapons, which must be supplied by the Marquis house of Zhaoyang Pavilion.


    According to the original agreement, the foundry and smelting workshops belonging to the craftsman''s club have always accounted for 20% of Zhaoyang tinghou''s house. Even if the price of quenched gold and iron is quite low by the nine world valves, the 20% share also brings unimaginable wealth to Zhaoyang tinghou''s house every year.


    Only in the previous two years, the Marquis house of Zhaoyang Pavilion had a little accumulation, which was mainly used to support Chen Hai''s leading elite troops in the eastern region of Jinzhou. In the follow-up, once a month, the components of a divine aircraft chariot and two divine aircraft crossbows will be sent to Lucheng. The war animals exchanged from the demon temple will also give priority to equipping the elite troops.


    When Chen Hai returned to juquanling, the resources used by the Marquis of Zhaoyang pavilion not only did not increase, but decreased in a short time.


    In order to recover juquanling and set up a seminar, on the one hand, we should maintain the normal operation of the seminar, on the other hand, we should build large-scale buildings and build palaces and halls. In addition to the life, practice and experimental sites of various tool refiners and puppet craftsmen, juquanling, as the fundamental place of the Marquis house of Zhaoyang Pavilion, has also gradually improved as a sect''s defense system.


    These will consume unspeakably terrible resources.


    In the spring of the 78th year of emperor Yitian, Chen Hai restarted two workshops outside the craftsman association system in juquanling, specializing in the manufacture of simplified Shenji chariots and Shenji crossbows.


    On his way to qintongshan in the East, Chen Hai disassembled the internal structure of the arrow array box, simplifying the symbol array structure of the arrow array box.


    Although the simplified arrow array box is much less powerful, it is also more practical.


    The previous arrow array box is equivalent to a yellow medium and low-grade magic weapon. It is very difficult to refine, which is also the biggest bottleneck for the manufacturing scale of Shenji crossbow.


    The simplified arrow array box can be refined by the craftsman and apprentice. Its power is far from that of the divine machine crossbow. It can also realize the continuous firing of five arrows. The five inch short crossbow filled with gold quenched arrows still has extraordinary penetration power within 300 steps.


    Shenji crossbow cannot be manufactured on a large scale. In the future, it will be used as a heavy weapon in the army. The simplified Tianji crossbow is much better than the existing iron arm bow and arm crossbow in the world in terms of stability, portability and shooting speed.


    The only problem is that the Tianji crossbow is made of nine levels of quenched gold and iron. Each crossbow weighs 120 kg. As a single soldier''s equipment, the crossbow is still too heavy. Only when it is made of eight levels of quenched gold and iron with higher strength and the weight is reduced to 40 kg, can it barely bear it.


    But in this way, juquanling needs to secretly transport 20000 or 30000 Jin of quenched gold and iron materials from Lucheng every month, which is also very troublesome.


    Fortunately, after Zhao Ruhui left taiweizong and joined the seminar, everything in Hexi remained the same, otherwise the channel in Hexi would be cut off, and the connection with Lucheng would be troublesome.


    The simplified version of the divine machine chariot is made to replace the mechanism puppet beast. Its main function is to carry quickly, not to rush into battle.


    After removing the heavy armor, the complex double wind array box driving structure is also changed to a much lower cost single simplified wind array box. The load of the puppet car in the field can also be maintained at more than 3000 kg, while the load passing on the driving road is as high as 78 kg, and the speed is comparable to the never tired fast horse, which is far from that of an ordinary good horse.


    This makes it really possible for an elite combat force to turn into combat by galloping thousands of miles a day.


    In the past, a good horse like qingcung horse could travel thousands of miles a day in a day or two, but it consumed too much horses and soldiers.


    Whether it is a simplified Tianji crossbow or a puppet car, it is not difficult for everyone to imitate it. However, the final problem is the manufacturing cost. Chen Hai set up a new workshop in juquanling to make Tianji crossbows and load puppet carts. After measuring the quotation given by juquanling, although it is necessary to ensure that the craftsman''s workshop has the ability to make Tianji crossbows and load puppet carts within their respective zongmen and Fengyi, it is much more cost-effective to buy them directly from juquanling if you really want to own them in batch.


    The puppet car appeared on the road leading to the nine world valves at the end of February.


    Of course, this is the first batch of puppet vehicles built. Even if the road is flat and continues to push for tens of thousands of miles or even tens of thousands of miles, there will be all kinds of possible serious situations - the effective driving distance of Shenji chariot is more limited. Before entering the battlefield, it is almost dragged by a large number of mules and horses - Chen Hai arranges a craftsman for each puppet vehicle Three craftsman apprentices so that problems on the way can be repaired at any time.


    Of course, everyone dared not be careless. They also prepared extra horses to drag the puppet car back to its destination when there was a problem.


    Chen Hai''s most fundamental purpose is to test the first batch of users. After the craftsman returns, the improvement data in all aspects will be summarized.


    Although the Tianji single crossbow and the puppet car are still a long way from the real requirements in Chen Hai''s mind, and there are too many imperfections, this does not hinder the love and persistent enthusiasm of many patriarchal aristocratic families.


    As long as juquanling can be built, in order to compete for the four or five hundred Tianji single crossbows and forty or fifty puppet vehicles built by juquanling every month, the nine world valves must first debate a distribution proportion.


    In particular, each batch of war weapons produced by juquanling will be slightly improved. Even if they are taken back as imitation samples, the large valve families can''t be willing to fall behind. Even if each batch of small modifications comes out, the first batch of prices are very high, and everyone can only recognize them by holding their nose.


    It will soon be the autumn of the 78th year of emperor Yitian. Even if there is nothing special on Juquan ridge, Chen Hai will keep meeting Dong Ning in the blood cloud wasteland for ten days to ensure that there are no accidents in the depths of the desert in the eastern region of Jinzhou.


    "Guo Hong decided to go to juquanling to practice. I mentioned it to me for two days, but Montenegro is short of manpower, and there are not many people who are good at Civil Affairs..." Dong Ning''s spirit idea was dragged into the blood cloud wasteland by Chen Hai. First of all, it is natural to tell Chen Hai about all kinds of headaches in Montenegro.


    Guo Hongzhi was originally the tribal leader near Montenegro. After Chen Hai captured the magic Moon Lake, he organized the tribes near Montenegro to invest. He was a rare figure who was good at both military, political and civil affairs in the Jingjue capital at this time. However, general fan Dachun and other brigands led troops to fight and combed civil affairs.


    Chen Hai brought Han wendang and Han Jian back to strengthen the strength of juquanling, but many civil affairs generals stayed in Montenegro. Unexpectedly, Guo Hongxuan took the initiative to ask to come to juquanling.


    "Guo Hong is good at mathematical derivation. You mentioned the dismantling of many forbidden systems in Lucheng before. Guo Hong said that he has learned a lot from his research during this period and wants to ask you face-to-face in juquanling..." it takes a lot of mental energy to condense a complete composite symbol array structure with divine consciousness, and this strand of divine consciousness may directly collapse, Dong Ning can only let Chen Hai pick up a piece of gravel. At the same time, she asked Chen hai to draw a little bit of Guo Hong''s recently deduced prohibition of a composite Rune array!


    The puppet''s separate sea awareness is extremely powerful. Chen Hai first drew the detailed structure of the composite Rune array, and then condensed it directly in the sea awareness. It is really a complete heaven machine prohibition structure that can lead Fenggang fire evil spirit.


    Whether this Tianji ban system can be used to build the wind array box of intermediate chariots, or what improvements need to be made to finally improve it, further tests need to be done, but it undoubtedly proves that Guo Hong is very talented in the research of Tianji ban system and other runes.


    "If you arrange him to come to juquanling quickly, whether the intermediate chariot can break through smoothly may be based on the Tianji ban he created." Chen Hai was very excited when he thought that the intermediate chariot might be successfully launched this year.
