Soon, those breaths gradually condensed, forming a long passage: There are chickens and rabbits in the same cage, with 35 heads on top and 94 feet on bottom. How many chickens and rabbits are there?

"Hmm? Isn't this an arithmetic problem?" Lynch was slightly stunned.

"Tsk tsk, this problem is difficult enough. No wonder even such powerful disciples in Henggu Sect cannot enter the second level." Gu Chen couldn't help but sigh.

Lynch was slightly speechless. Although this question was a bit difficult, it was not too difficult. As long as people who have studied on Earth could solve equations and other problems, there was almost no big problem.

However, Lynch then understood that the Holy Ancient Realm is equivalent to the ancient times on Earth, and the level of civilization in this area has not developed to that level.

Of course, there were also these problems in ancient times on Earth, and some historical books recorded them, but there was no such good arithmetic solution at that time.

This is the same with this holy ancient realm, so it has become a problem in their eyes.

"Lynch, can you answer it?" Gu Chen couldn't help saying: "If you can't answer it, I won't blame you. After all, it's hard to calculate it in ten breaths for those geniuses in the era of Origin."

But just after he finished speaking, Lynch said directly: "23 chickens and 12 rabbits."

There are exactly 35 heads and 94 feet in total!

That is, the moment after Lynch answered, suddenly, a flash of light flashed on the stairs, and all the breath condensed, making this illusory and transparent stairs become substance.

"Is the answer right in one go?" Gu Chen was stunned for a moment, the speed was beyond his imagination!

"It's not difficult, right?" Lynch said lightly.

"Uh..." Gu Chen was choked for a moment. Why did he feel a sense of pretending to be filled with the air?

"But now, you should be able to enter the second floor." Lynch was a little expectant, and he stepped down to the steps.

Soon, he took steps and stepped into the second floor step by step.

The same as the first floor is that the second floor is also a circle-shaped bookstore.

However, this second level of breath is filled with some strong, strong, special and terrifying aura.

"The worst of this second level are the pseudo-Wuji Treasure-level martial arts, secrets, and martial arts!" Lynch just glanced at it and could see the powerful fluctuations in the secret realm of those martial arts.

Gu Chen was also surprised: "There are at least hundreds of thousands of books on this bookstore, that is to say, there are hundreds of thousands of top martial arts, and any martial arts here is enough to make a strong man famous."

Even Gu Chen was used to many big scenes, he was shocked by the quantity and quality of the books here.

This is simply a treasure house. The foundation of Henggu Sect back then can truly create extraordinary powerhouses in batches.

"Senior Brother Gu Chen, can these books be taken away?" To be honest, Lynch's heartbeat inevitably accelerated.

The worst here are all martial arts at the level of the pseudo-Wuji Treasure, and there are many real martial arts at the level of the Wuji Treasure, and even some martial arts that are stronger than the Wuji Treasure.

If I could take away a few books, it would be enough to make Lynch extraordinary.

"Meow~" At this time, the little white cat also smelled something delicious, and a head poked out from Lynch's clothes.

Gu Chen coughed twice: "If I could take it away, the place would have been emptied long ago. Moreover, if you force it away, you will be punished by Huiling here and even pushed it out directly!"

"Okay, then I'll take a look and understand it, and I should have gained something!" Lynch said.

Gu Chen nodded: "Just choose what works for you. Learning is too complicated and it's just a burden."

Lynch still understands the principle of taking only one scoop of water.

"Little white cat, you should be more at ease. You can't eat the books here." Lynch patted the little white cat's head.

The little white cat said "meow" with a little depressed depression and could only get back into Lynch's clothes in disappointment.

Next.

Lynch walked around this floor, and carefully selected the details.

Although time has passed, every book on this bookshelves is spotless and as new as it is.

Moreover, each book has different fluctuations, mysterious, weird and extraordinary.

Lynch was like entering a treasure world, and every book was enough to attract attention. For a moment, Lynch felt like he couldn't start.

"Junior brother, go to the bookshelf in the ninth row in front, there seems to be a good martial art there." Gu Chen felt it and pointed the way.

Lynch turned around and came to the ninth row of bookshelf. Sure enough, what attracted him was a very ragged book.

In fact, there is nothing strange about this ragged book, but the books in this library are all spotless and brand new.

This ragged book seems a bit abrupt when it is placed in it!

It was like a stone appeared inside a pile of gold.

"Senior Brother Gu Chen, you are talking about this broken book, right?" Lynch was stunned for a moment.

"It's it." Gu Chen said affirmatively: "Look, this book seems very different."

Lynch picked up the broken book and opened it. The first page reads - "The True Soul Demon Refining Art"!

Next is the second page, which has annotations on the cultivation of soul power, including text and graphics. Moreover, it advocates that the cultivation of soul power is to refine the soul into a demon soul, so as to achieve a special soul power that is stronger than others.

"Isn't the cultivation method above similar to my dark demon soul power?" Lynch was surprised.

It is true that there are all kinds of wonders in the world. The black demon soul power obtained by Lynch Qiaoran actually started to study it as early as the era of origin.

Moreover, this "True Soul Demon Refining Art" records in a very detailed way how to cultivate the soul into a demon soul, and can also separate the three souls and seven spirits.

The more Lynch looked at it, the more numb his scalp felt, which was an unprecedented miracle.

Moreover, it is very suitable for him to practice. He can even directly choose the previous stages, start from the middle, and finally cultivate a real demon soul.

However, there are some ways of practicing, which are too harsh and need to absorb other people's souls, which makes Lynch a little difficult to accept.

After Lynch finished reading the entire book of "The True Soul Demon Refining Art" and after Lynch savored it carefully, he thought about it.

"It is absolutely not advisable to absorb other people's souls, but there are many things that can be refined in "The True Soul Demon Refining Art". Otherwise, I will integrate "The True Soul Demon Refining Art" with the "The Heaven and Earth Soul Power Art" I originally practiced."

After the idea of ​​Lynch was born, he felt like he was trapped in a demonic obstacle, constantly deducing, constantly evolving, and indulging in it.
