Chapter 722 Collection of Books in the Valley, Test Content!

Hearing Shu Ling's words, Luo Chen was relieved.

If it's only half a day, it's still acceptable, but I don't know how much time will pass in this illusion for half a day outside.

However, Luo Chen didn't ask Shuling this question. Looking at the huge bookshelves filled with books, Luo Chen sighed softly and said to Shuling, "Senior please ask questions."

He really didn't expect that after he crossed over, he would still be unable to escape the fate of having to take an exam!

Shu Ling didn't say much after hearing the words, raised his hand a little, and a golden light emerged from his fingertips, turning into a huge golden paper suspended in mid-air, with several lines of pale golden characters looming on it.

Luo Chen hurriedly turned his gaze to the paper, and glanced over the topics on it, but found that it was not only him, but even Jianzu Jianjing had no content related to these topics!

Luo Chen was not surprised by this. Jianzu was obsessed with swordsmanship and alchemy, and didn't care about other things. All he knew was some common sense and some secrets from the mainland.

However, the topic given by Shuling involved various aspects, and it was not news that the outside world could easily get. It was normal for him not to know the answer.

"Ugh……"

With a light sigh, Luo Chen wrote down a few questions, then turned his eyes to a bookshelf, and with a flash, he appeared directly at the top of the bookshelf, and picked up a thick collection of books to read.

Luo Chen's speed of flipping through books is not slow, his own understanding is not bad, and after the improvement of aptitude, his understanding has been raised again, and he can easily remember it.

Soon, Luo Chen memorized a book in his heart, and immediately picked up the next book and read it quickly.

In the center of the cave, when Shu Ling saw this scene, a faint smile appeared on the corner of his mouth, and there was an inexplicable look in his eyes.

"It looks like this kid is going to fail," Shu Ling thought to himself as he looked at Luo Chen's back.

There are tens of millions of books in this cave, and the flow of time in this illusion is a thousand times slower than that of the outside world. For half a day in the outside world, almost three years have passed in this illusion.

However, even he couldn't finish reading the collection of books in this cave within three years. If he couldn't discover the mystery, he wouldn't be able to pass the test at all!

Luo Chen didn't seem to find the problem, he quickly took out the books and flipped through them, and quickly read the books in the cave with his unforgettable ability.

Seeing this scene, Shu Ling shook his head gently, and then his figure disappeared.

After Shuling disappeared, Luo Chen's movements suddenly stopped, and he turned to look at the location of Shuling, with an inexplicable smile in his eyes.

"This illusion can't trap me," Luo Chen shook his head and said softly.

Before he started reading the first book, he had already used a secret technique called 'Delusional Eye' recorded in the Primordial Devouring Magic Art to explore the surroundings.

Under the blessing of Delusional Eye, Luo Chen clearly discovered the mystery in this cave.

Although there are many books on the bookshelves around here, there are only a few hundred books that actually have physical possessions. Obviously, those more than a hundred books are the key to answering the question!

However, Luo Chen didn't rush to pick out the hundreds of books, but took a few books from the bookshelf to read after dispelling his delusional eyes.

And because of this, Luo Chen discovered something very interesting...
