Li Zhi, who is reincarnated, has more of a sense of self-defense than others, which is due to the experience of the two lives, and it is also a cautious and cautious mentality from the bones, because he does not want to lose all his ambition and pride due to indiscretion in small details, and live in vain for two lives.

Li Yu didn't know what Li was thinking, and his expression was still in a solemn alert: "What Mr. Li said is right, although the people sent by Li Shangshu are trustworthy enough, but the current situation is a little weird, Li Tang's forces have been infiltrated for many years, it is difficult to keep those who are deeply hidden, the crossbow is very important, it is necessary to be cautious!" ”

Li Zhi mentioned that the secret discussion in the military that day was deliberate, and all the participants were considered many times, and the people who were suspected of defecting to the army existed, such as Li Yu, Li Ying and others, who were ostensibly in the core of the military surnamed Li, and the reason why they did not appear was that there was a reason for the concealment of their identities.

Li Yu and Li Ying of the Songwang Mansion, just like the second generation Li Ping, Li Fanghe and his son Li Xing and Li Shanchao, belong to the other line of people in the mansion, and on the surface, they are in a three-legged position with King Song and his second son Li Hao and Li Changlin, and Li Hao participated in that party.

In the Ten Princes' Mansion, there are only factions in the Song Wangfu, and there is a reason why the Song King is given the title of a king, because the second generation of the Song King and his brother Li Ping were born to a mother, Li Ping's biological mother has a martial arts blood, and when the Song King was alive, the battle between the ladies was very fierce.

The order of the ten kings is a rather complex focus of light and dark contention among the forces in the palace, out of comprehensive considerations, the rather complex struggle for power within the Songwang Mansion will therefore be pushed to the head of the ten kings, which is also a means to use the first palace to balance the interests of the ten kings.

And the eldest son of the third generation, the third son of the third generation of the family formed another big in the house, is not used to the second generation of King Song since childhood doting on the second son Li Hao, of course, this is the secret chess laid out before the current King Song inherited the throne, no one is willing to be used by others in their own family affairs, even if one side is used to decide the royal family.

The situation is too complicated, so I won't repeat it here, but more than ten years later, this secret trick has come in handy for a crucial step, which is a later story, not to mention it for the time being!

The reason why Li Zhi trusts Li Yu is because he has learned it secretly, and Li Yu is not confident that he is trusted because he heard him say the deep meaning, but because he feels that Li Zhi is so unshy about it, precisely because the crossbow matter is very important.

Ming Tong walked away when the two of them discussed the matter, which was the professional ethics of a royal dojo Taoist who frequently interacted with various royal families, and it was also a compulsory course for the best conservative elites.

In fact, it is extremely simple for a cultivator of a certain realm to have the intention to spy on the secrets of other people's conversations, and in order to avoid suspicion, often the old monarch palace will instantly restrain the aura of his body, which is also the foundation for the cultivators in the palace to gain a foothold.

"This kind of behavior is natural and will not be suspected, and your excuse is to escort those thousands of Tang knives. Of course, the probability of someone being bought is extremely small, we can't underestimate Li Shangshu, he can be entrusted with a heavy task at such a young age, and his brain is not ordinarily good! I asked Brother Shoushan to follow him to Cliff Mountain for another more important purpose, which was to inform Adjutant Has-Erdun that in addition to the construction of the military factory in the canyon, such classified ordnance would be developed and a more hidden position would be reopened! Tell him that it's the perfect place to be! ”

The first line of heaven mentioned by Li Zhi is the deepest part of the mountain that seemed to have no way out, under a mountain wall, a magical line of heaven formed by two mountain wall faults, and the only way to enter the hundreds of zhang space is the narrow stone alley, and the deeper bottom of the pool, leading to the grotto river channel of the lake outside.

There is this ordinary insight can not penetrate the heavy ridge is separated from the unknown place of ordinary people, undoubtedly the best place to place the development of new products, and it is very easy to defend, and the bottom channel of the pool can ensure the secret entry and exit of bulk items.

The matter was important, Li Yu did not ask the doubts in his heart, "As long as the adjutant knows the location!" In fact, due to the existence of the arsenal, there will be no problem with the security there, but I have heard that there is no shortage of the most powerful cultivators in the army! ”

"Not only that," Li Zhi pointed to his light cavalry, "including the ordinary guards there are all cultivators, and these subordinates of mine may not be able to withstand a sentry on the periphery!" Okay, I'll go and ask the chief of the Ming channel to come over, let's discuss the start of tomorrow's construction! ”

When the specific project process steps were determined, the banquet that night ended in a hurry, and there were more important things in the ironware workshop than the construction of Tianji Pavilion.

Li Zhi and several key people rushed to make it overnight, and more craftsmen were also driven away to rest in the middle of the night, these people are ordinary people, they didn't stop last night, and it is difficult to have the physical strength to support the second night.

And the few people left at the scene, secretly infused with his true qi, were more sober than usual, but they only cared about burying their heads in the work, and very few people noticed that their spirits were refreshed again.

The next day, the first crossbow was finally assembled, Li Zhi did not rush to gather people to watch the demonstration, but asked people to set up the markers two miles away, and sat in the corner, to explain to Na Risong in detail the use of the modulation mechanism of the tensioning spring machine.

The machine is a machine part that fires the arrow on the crossbow, and the tension spring chain is interlocked, and it can be arbitrarily deployed according to the crossbow use environment.

And the machine he designed can be called wise, in the assembly process, with a very fine steel wire fastened between the tension spring and the chain, does not affect the tension modulation of the lateral repeated toggle force, but once the crossbow body is opened longitudinally to reveal the inner structure, the steel wire will be broken, the tension spring chain will immediately collapse everywhere, there is no detailed pattern guidance, and then want to reorganize it The difficulty is no less than the redesign of the crossbow.

This kind of explanation can only be fully grasped by Narisong, and others are separated to teach a part of each, and there is no coherent node between each other, and it is impossible to generate transmission between the machine and the tension spring chain without Narimatsu personally adjusting.

After more than an hour of teaching and suffering, the rooster crowed three times, the sun was high, the sun was shining brightly, and the craftsmen in the tent got up one after another.

Without Li Zhi's explanation, everyone gathered one after another without waiting for washing, including Mingtong and Li Yu, who hurriedly entered the workshop to listen, and soon Li Zhi led them to the wilderness outside the courtyard.

The huge crossbow body was still quite heavy, and it required a few people to move forward, and the field was a hilly part of the mountains, and the carriage could not be used at all.

Although there is only one trap crossbow, it is equipped with ten sets of arrow chests, each with ten arrows, which is much easier to create than a trap crossbow.

"Between one and two miles from here, there are marked target positions every fifty zhang, and according to the limit tension I have speculated, the difference is in between, so it is good to have a more accurate range understanding!"

Coming to a mound, Li Zhizhi pointed to a distance and explained that one mile is roughly the same as one hundred and fifty zhang, which means that there are three targets erected between one and two miles.

The people in charge of the care are Mo Shao, Bai Yu and others, Li Zhi's insight is enough to cover more than ten miles, and he is ready to launch in a flat place, and at the pre-agreed hour, he has already hidden his body when he sees that the caretaker has already hidden, so he waved down and ordered the first arrow to be launched.

The first arrow box needs to be tested with a single one, and from the second box onwards, it will gradually increase by two or three, in order to test the stability of the range, and each test must be well documented until a crossbow has been tested thousands of times without stopping.

Because after so many shots, the crossbow string will be stretched or broken, and the crossbow arm will gradually fail, but this is not a problem, because there are other special accessories that can be replaced at any time, and the replacement of the crossbow machine is extremely easy, and it only takes a minute for a skilled soldier to complete, of course, this is also the subtlety of the modular design of Li Zhi's design.

The person who fired the first arrow was specifically pointed out by Li Zhi as Li Yu who had cultivation, and such a giant crossbow that can produce terrifying tension still needs a third-level hunter with self-protection ability, after all, the bowstring that bears huge traction is not tested, and no one can guarantee that the bowstring will not be broken due to the strong tremor force.

With the piercing sound of the rolling mechanism activating, the long-bowstring of several feet was also stretched like a full moon in the blink of an eye, and a fierce momentum rose in response, which actually caused the air in the surrounding two zhang to run noisily, making Li Yu's clothes windless and automatic.

Immediately after that, the faint light and shadow like the sword on the bowstring flickered, and in an instant, the supreme coercion of the powerful and domineering rhyme suddenly rose, and an invisible coercion spread in an instant, and with a "boom", the arrow had passed through the void with the dazzling light, and a force so powerful that it seemed to destroy everything rose, and wherever it passed, the void turbulence surged, and the spatial airflow was torn to pieces in an instant.

The terrifying aura of destruction erupted as short as a streamer, but in the eyes of Li Zhi and the other cultivators, an unrecognizable dazzling essence light also rose up in the sky, and in the flickering light, it suddenly erupted like an aurora, stirring up a storm and clouds between heaven and earth.

It was too late, it was fast, the arrow was unstoppable, and it slashed through the void with a momentum like a bamboo, pulling out a terrifying air that made the scalp tingle and the sound of explosion, and a terrifying aura suddenly filled the accompaniment, and the illusion of invisible silver light swayed a colorless brilliance, and in the blink of an eye, it penetrated through three huge animal skins to make a target, and fell down more than ten zhang away from two miles away.

"Mr. Li's crossbow is really domineering and terrifying, a single arrow actually broke through two miles away, and the strongest crossbow in the world before was only a hundred zhang range, right? Your arrow has been far exceeded several times, and what is even more surprising to me is that the arrow of the crossbow is not an arc trajectory in the traditional sense, but a straight flow potential, which shows that the strength and speed of the arrow have reached a terrifying situation! ”

This is Mingtong couldn't help but exclaim loudly, others don't have his master-level insight power, and when they hear the power of the crossbow arrows is so terrifying, they can't help but gasp.

"After Brother Shoushan and Brother Narisong each shoot an arrow and demonstrate, if they don't find anything abnormal, everyone who is interested will also come forward and try it!"

Without explaining the ingenuity, Li Zhi smiled and instructed, he was also excited in his heart, after all, it was the first time to convert theory into practice, and the sense of glory also appeared in him.

Each of the next arrows still drew screams from everyone, and although most people couldn't see the astonishing power of the moment the arrow was launched, the sharpness in it was almost extreme, and no one dared to try to face the horror of such a terrible arrow.

Because it is a dual-track design, every two arrows are fired, it is necessary to add a crossbow machine firing end, and each crossbow is designed with six tension springs inside, in fact, on the tenth box of ten arrows in unison, there is a very short machine bracket conversion between every two arrows, because it is operated by one person, or it is necessary to pull the trigger five times in a row.

Six tension spring machine design, one of which is a standby setting, the tension of each mechanism is different in advance, the first strike is not necessarily the first, the difference in the rate of fire is unequal, it seems that ten arrows arrive at the same time, but in fact, the changes occur in an instant. You can't see it with the naked eye.

The purpose of this effect is to target especially the master figures who can discern the incoming arrow, and the difficulty of grasping the law of instantaneous change is the root cause of deterrence against them.

If dozens of arrows from several crossbows arrived, it would be really difficult for ordinary first-level masters to parry.

This time, in this drill, only four arrows were fired at once, and the terrifying momentum was far greater than that of a single arrow, and then to the scale of the last ten arrows, in addition to the cultivators, the craftsmen who were ordinary people had already been so frightened by the murderous aura around the crossbow that they didn't even dare to easily confide in the sound of panting.

There were a few timid people who couldn't help but tremble their legs, and there were signs that they were about to be scared to pee.

It was the power of ten arrows, and it had already formed a terrifying penetrating force like a sharp man, and at the moment of launch, it seemed to carry the power of a thunderbolt, and the horror caused by a terrifying and terrifying killing aura was far from what ordinary people with physique could afford.

Ten boxes of arrows, according to the number of fired, five of the tension spring machine including the design is different, the range of the three targets are also involved, of course, the shorter the range distance, the speed and power drawn by the tension naturally varies.

After a launch that lasted for more than an hour, Mo Shao, Bai Yu and others also hurried back, and the targets of single arrows and multiple arrows were also marked respectively.

The crowd gathered around to analyze the differences, and before they knew it, it was noon.

The result of the discussion undoubtedly proved that the development of the crossbow had fully met the previous design standards, and after everyone let out a deafening cheer, the third elder Wu Dao Xiao also laughed and galloped over from a distance.

This person disappeared after getting the Qiankun bag last night, and no one knew where he went, but in the eyes of Li Zhi and Mingtong, the smug look on this person's face obviously concealed a sense of mystery that was difficult for others to know, and it must have been something hidden in the middle of the night using the Qiankun bag!
