What is the strength of the fifth-order demon beast, Yue Yu actually doesn't have any accurate concept. I only know that the beasts of this class can only be dealt with by the strong above the innate level. If they were serious, even if there was only one, it would be enough to cause the Yuejia City, which had more than a thousand martial artists, to suffer heavy losses, and even the clan would be wiped out.

And as far as Yue Yu knew, that lion crocodile beast was a genus of low-level spirit beasts, although its body was only at a medium level among high-level demon beasts. However, it is extremely powerful, covered in crocodile armor, except for some vital parts, there are almost no flaws. In terms of overall combat power, even if it is not as good as those ordinary sixth-order demon beasts, the difference will not be too far. And the so-called organ master was able to have the power to confront it, which really shocked Yue Yu. For the first time, he thought of the terrifying war machines in his previous life.

Of course, Yue Yu was just thinking about it. If the nuclear-powered fighter warships of his era could come to this world, maybe they would really be able to fight against those high-level demon beasts. But in terms of the mathematical and physical knowledge of Dongsheng Continent, which had just entered the enlightenment stage, it was absolutely impossible to possess those things.

――But it was precisely because of this that Yue Yu was very curious about the trick.

However, Yue Yu felt a little regretful that although there was some knowledge about the mechanism in the Yue family's collection. It even involved the creation of unbelievable puppets such as mechanical wood people and mechanical wood beasts, but on the whole, it was not able to break away from Yue Yu's cognitive category.

And to the extent that these puppets are at most, they can only play the role of serving tea and pouring water. Aside from its sophistication, as well as its strange and completely disobedient production method, which surprised Yue Yu a little, it was far from enough to fight even the lowest-level human warriors and demon beasts.

The only valuable thing is probably the strange lines on the bodies of these wooden figures, which are carved with cinnabar silver mercury, which should be regarded as energy transmission lines. Then there are the demonic power crystals and spirit stones that are mentioned many times in the book as the driving energy of the wooden golems.

"Could it be that the one who can fight against the lion crocodile beast is also a similar puppet?"

When he put down the last miscellaneous book on mechanical techniques, Yue Yu's brows were already furrowed. In the usual sense, the so-called organs should be equated with the special surnames that are bulky and difficult to move. However, with the exception of this puppet, only with its high mobility surname can it keep up with the speed of the demon beast and fight against it.

However, such a puppet, Yue Yu couldn't imagine it. There are some descriptions in those books, which are said to be based on demon bones as the torso and a huge fine iron sword as a weapon, which can be as high as a hundred zhang, and can pull mountains and rivers with strength. It's just that I don't know, what is the specific appearance and fighting method, and what is the situation? How does the height of a hundred zhang resist gravity?

Shaking his head slightly with a smile, Yue Yu temporarily put aside the exploration of this technique. I still didn't understand how those mechanics fought against those fifth-order demon beasts. It seems that if he wants to really understand the mysteries, he still has to find a chance to see it with his own eyes.

In the following time, Yue Yu focused his energy on those medicine books and medical books. Compared to the few martial arts secret books and tricks, the number of the former is really huge. Even at Yue Yu's speed of turning a book, it took a whole day to memorize only half of it.

Only in terms of preciousness and practical surname, this is indeed worthy of the Yue family's thousands of years of secrets. Just the Peiyuan Pill, Yue Yu found several prescriptions composed of different herbs, and there were countless kinds of herbs that Yue Yu had never seen or heard of. There are also many other pills that can help him practice internal rest to a certain extent.

For example, in a medical book called "Inner and Outer Su Wen Ji", I found a medicinal bath recipe called Zixuesan, if it can be used after high-intensity martial arts practice, it can play a role in soothing muscles and strengthening muscles and bones. Whether it is him or Ran Li Lin Zhuo, they can all be used.

There is also a pill called Luo Wei Pill, if it is combined with appropriate acupuncture techniques, it is extremely beneficial to the development of meridians, and it is exactly the medicine that Yue Yu needs most now.

However, among the more than 1,000 books that are three feet thick, there is not a single one that can directly help improve his strength, and he can get his hands on it at this stage.

The only few that can quickly increase the cultivation method to a certain extent are not the elixir that is needed and the cost is extremely expensive. It's just that the requirements for users are too high, and basically it should be a drug for the congenital strong.

For example, the 'Yi Yuan Dan Formula' that Yue Yu valued the most, the materials required should be the lowest and easiest to find among all the recipes. Although the auxiliary medicine in it is also extremely precious, it can be found within the control of Yuejia City. But the problem is that its main medicine is the bone marrow and demon pill of the fifth-level demon beast, and it is difficult to get hold of it even if it combines the power of thousands of martial artists in the entire Yuejia City. Yue Yu would not even think that the entire clan would make such a sacrifice for himself.

As for the other recipes, the degree of perversion is even more than one. Sometimes, even if it is an adjuvant, it is worth as much as 10,000 gold, and it is estimated that if the entire Yuejia City is sold, it will not be able to buy a quarter of the materials required for the entire prescription.

But if you think about it, it's no wonder that if the Yue family is outside of Peiyuan Pill, there are really more affordable prescriptions. Then today's high-level martial artists are far more than the current number.

There was nothing to be found in these Yue family's collections, and Yue Yu was extremely depressed when he went home that day. And for several days in a row, he still rushed to the city lord's mansion early in the morning to check the remaining books, and then returned disappointed every day.

This made the faces of those elders look ugly. It wasn't until Yue Yu finally put down those miscellaneous books completely and began to ask them some questions about martial arts that he smiled again, but only the second day, including Yue Tianmeng, who had the highest achievement in martial arts, was dripping with cold sweat at the end of the day, and his heart was full of excitement, surprise and luck.

――In the eyes of these old men, Yue Yu was not doing his job at all. However, when Yue Yu really began to divert his attention to the martial arts and showed that amazing talent, they felt that they couldn't stand it again. Every question Yue Yu asked was either the subtlety of the martial arts they had cultivated, or some of the more critical flaws. In many places, they didn't even pay attention to it, and they couldn't answer. And some of Yue Yu's insights were unprecedented, which made them feel deafening and empowered.

And after a few days in a row, although several old people were ashamed of their ignorance, they also gained a lot. I felt that Yue Yu's questions made them both look forward to it and be a little apprehensive. Since he hadn't noticed it, the smile at the corner of Yue Yu's lips was better than the other.

or was born in the military, Yue Yu didn't know how to deal with interpersonal relationships in his previous life. Even in the mercenary world full of conspiracy and treachery, most of them are straightforward. However, for these old men who are as martial as their lives, he naturally knows clearly what kind of way he should use to win favor. After all, in the next few years, he may need to rely heavily on the power of the clan.

-- Therefore, it is important to show one's own worth, and it is also indispensable to have a good relationship with the powerful people in the clan.

Of course, the past two days have not only been out of the court, but also from the communication with these elders, and he has also benefited a lot. There are many incomprehensible places, if you only understand them by yourself, it will inevitably take dozens of years to make a difference. Even if time permitted, he would like to continue this life forever.

However, on the fifth day, the clan competition finally reached the final stage. And on the evening of the end of the day, Yue Yu also left the City Lord's Mansion early, went home and got into the carriage that Yue Zhang's family rushed to the clan ancestral hall.
