Chapter Eighty-four: The Easy-to-Understand Elixir Formula

  The strength of the five-tiered demon beast, Yue Yu actually didn't have any accurate concept. Only knew that at this level, only those with innate abilities above could cope. If they were serious, even just one would be enough to make the Yue family city, which had over a thousand martial artists, suffer heavy losses, and possibly even lead to the downfall of the city.

  As far as Yue Yu knew, the Lion Crocodile Beast was a lower-ranking spiritual beast, although its body was only mid-tier among high-ranking demonic beasts. However, it had immense strength, with crocodile armor covering its entire body, leaving almost no weaknesses except for some vital areas. In terms of overall combat power, even if it wasn't as strong as ordinary sixth-rank demonic beasts, the difference wouldn't be too great. And yet, that so-called Mechanic was able to withstand its attacks, which left Yue Yu shocked and amazed. He immediately thought back to the powerful war machines from his past life.

  Of course, Yue Yu was just thinking about it. If the nuclear-powered aircraft carriers of his era could come to this world, they might be able to contend with those high-ranking demon beasts. But with the mathematical and physical knowledge of the Eastern Victory Continent, which had only just entered the Enlightenment stage, it was absolutely impossible to possess such things.

  Perhaps it was because of this that Yue Yu became even more curious about the agency's techniques.

  However, what made Yue Yu slightly disappointed was that among the books stored in the Yue family, although there were some knowledge about mechanical techniques, including even more incredible puppet manufacturing such as mechanical wooden men and mechanical wooden beasts, but overall, they did not go beyond Yue Yu's cognitive scope.

  At most, these puppets can only serve the purpose of serving tea and water. Apart from their exquisite craftsmanship and bizarre manufacturing methods that completely defy physical laws, which left Yue Yu slightly astonished, they are far from being able to withstand even the lowest-ranking human warriors and demonic beasts.

  The only valuable things are probably the strange lines drawn with cinnabar and mercury on these wooden puppet bodies, which should be used as energy transmission channels. There are also the demon power crystals and spirit stones mentioned in the book multiple times, which serve as the driving force for the wooden puppets.

  "Could it be that the ones capable of withstanding the Lion Crocodile Beast are also similar mechanical puppets?"

  When Yue Yu put down the last book on mechanism, his eyebrows were already tightly furrowed. In general terms, mechanisms should be synonymous with clumsiness and difficulty in movement. However, this mechanical puppet was an exception, and only its high mobility allowed it to keep up with the speed of the demon beast and confront it.

  However, such a mechanical puppet, Yue Yu couldn't imagine it at all. Those books did have some descriptions, saying that they were made with demon bones as their body, and huge iron swords as their weapons, reaching heights of over 100 meters, with strength capable of uprooting mountains and rivers. But what about the specific appearance and combat methods? And how would a hundred-meter-tall body counteract the gravitational force of the earth?

  Smiling, Yue Yu temporarily put down the investigation of this mechanism. In his heart, he still didn't understand how those mechanism masters could counterattack against those fifth-grade demon beasts. It seemed that if he wanted to truly understand the mystery, he would have to find an opportunity to go and take a look for himself.

  In the following days, Yue Yu put all his energy into those medical books. Compared to the few martial arts and mechanism manuals, the number of medical books was truly staggering. Even at Yue Yu's speed, which was akin to flipping through a book, he only managed to roughly memorize half of them in an entire day.

  In terms of preciousness and usefulness, this is indeed the secret treasure of the Yue family for thousands of years. Just from the Pei Yuan pill alone, Yue Yu discovered several prescriptions made from different medicinal herbs, and recorded countless types of medicinal herbs that he had never seen or heard of before. There are also many other pill formulas that can help him with his internal breath cultivation to a certain extent.

  For example, in a medical book called "Nei Wai Su Wen Ji", I found a medicinal bath recipe called "Zi Xue San". If used after high-intensity martial arts training, it can relieve muscle soreness and strengthen tendons and bones. Whether it's him or Ren Lixing, they can both use it.

  There is also a kind of pill called Luowen Pill, which can be very beneficial for opening up the meridians when combined with suitable acupuncture techniques. It's exactly what Yue Yu needs right now.

  However, among these thousands of books that are over three feet thick, there isn't a single one that can directly help him increase his strength and is currently within his reach.

  Only a few can rapidly increase their cultivation base to some extent, not the required spiritual medicine is hard to find and extremely expensive. It's just that the requirements for the user are too high, basically those should be drugs used by innate strong people.

  Just like the 'Easy Yuan Dan Fang' that Yue Yu values most, the materials required should be the lowest and easiest to find among all prescriptions. Although the auxiliary medicines inside are also extremely precious, they can be found within the control of the Yue family castle. The problem is its main medicine, which is the bone marrow and demon core of a fifth-level demon beast, and it's feared that even with the combined strength of thousands of warriors in the entire Yue family castle, it would still be difficult to get their hands on it. Yue Yu wouldn't think that the whole clan would make such sacrifices for himself.

  As for other prescriptions, the degree of abnormality is even more one after another. Sometimes, even a single auxiliary medicine can be worth as much as ten thousand gold coins, and it's estimated that selling the entire Yuke City wouldn't even cover a quarter of the cost of the materials needed for the entire prescription.

  But thinking about it, it's no wonder that if the Yue family had a more affordable prescription outside of Pei Yuan Wan, then the number of high-level martial artists today would be far more than it is now.

  In these stored books of the Yue family, there was nothing to gain. When Yue Yu returned home that day, his mood was extremely depressed. And for several days afterwards, he still rushed to the city master's mansion at dawn to search through the remaining books, only to return in disappointment every day.

  This made the faces of those elders look worse one day than the next. Until Yue Yu finally put down those miscellaneous books and began to ask them some questions about martial arts, they reopened their smiles. However, only on the second day, including Yue Tian Meng, who had the highest achievement in martial arts, everyone was sweating profusely all day long, with a complex taste of excitement, surprise, and luck mixed in their hearts.

  Before, Yue Yu was considered to be not diligent in his work by these elderly people. However, when Yue Yu truly began to shift his attention to martial arts and revealed that astonishing talent, it gave them an unbearable feeling. Every one of Yue Yu's questions either hit the precise point of their refined martial skills or touched on some crucial flaws. Many places, even they themselves had not noticed before, were unable to answer. And some of Yue Yu's insights were unprecedented, making them feel as if their ears had been cleaned and their minds enlightened.

  In the following days, several elderly people not only felt ashamed of their ignorance but also gained a lot. They found Yueshuo's questions to be both exciting and intimidating at the same time. Unbeknownst to them, the subtle smile on Yueshuo's lips grew more pronounced with each passing day.

  Perhaps due to his military background, Yue Yu was not good at handling interpersonal relationships in his past life. Even when he mixed with the mercenary world filled with intrigue and deception, he mostly went straight to the point. However, for these few old men who were obsessed with martial arts, he naturally knew what kind of approach to use to gain their favor. After all, in the next few years, he might need to rely heavily on the power of his clan.

  So showing one's own value is important, but also building good relationships with powerful figures within the group is equally indispensable.

  Of course, these two days are not simply to please others, and the exchanges with these elders have also benefited him a lot. Many things that he didn't understand before, if he had to figure them out on his own, would have taken dozens of days to accomplish. In fact, if time allowed, he would have liked to continue such days forever.

  However, on the fifth day, the clan competition finally reached its final stage. On the evening of that day, Yue Yu also left the city master's mansion early and returned home to board the horse-drawn carriage driven by Yue Zhangshi to head to the ancestral temple.
