The tutor guarded the cabinet showed a strange look.

Usually, no one can exchange this tantra, but today there are two people who exchange it in succession.

"Yes!"

Chen Yu nodded.

"This secret science requires 60,000 magic-free points. You are a freshman, so there shouldn't be so many. You can exchange it for the previous article first, only 20,000 magic-free points!"

The tutor guarding the cabinet looked at Chen Yu.

The first article is the introduction and the basics, and the next article is the essence, so there are differences in the exchange of magic points.

Moreover, "The Demonic Shadow" has a higher grade and is originally a higher price, but due to its difficulty, few people exchange it, which reduces the number of exchanges for the Demonless Points.

"good!"

Chen Yu gritted his teeth and agreed.

This secret school has a very high grade, and the price is already very cheap.

After receiving the first article of "The Demonic Shadow", Chen Yu quickly left.

"I'm poor all of a sudden!"

Chen Yu couldn't help but sigh.

The magic-free spots obtained by selling demon cores were left in a blink of an eye, and they were really like flowing water.

When he returned to the cultivation cave, Chen Yu immediately started to read it.

"The last article alone is enough for me to practice."

This secret learning is extremely difficult, and the first article is enough for Chen Yu to practice. When you earn the Demonless Point, you will exchange it for the next article.

After three days of retreat, Chen Yu familiarized with the first chapter of "The Demonic Shadow".

"This secret science requires extremely high physical fitness. If you have poor physical fitness, you will not be able to use it for too long!"

After reading the previous article, Chen Yu made a summary.

In addition, the speed increase of this secret method is indeed amazing. If it is combined with Chen Yu's heart explosion, it will be even more terrifying.

On this day, he stood up and left the cave.

In the practice of "The Demonic Shadow", Chen Yu did not slacken in his competition with Duan Hao, and was preparing to take a look at the "Shaken Valley" mentioned by Teacher Liu.

Soon, Chen Yu came to a huge purple light barrier, and only saw the general appearance of a huge valley from outside.

At the entrance, four black armored guards, with amazing breath, up to the innate.

"The Wind Valley requires three thousand magic-free points per month!"

A black-faced guard spoke coldly.

After paying three thousand demon-free points, Chen Yu had even fewer demon-free points in his hands.

Fortunately, the practice of the cave and the Shafeng Valley are both a one-month period, so there is no need to worry at present. Moreover, the Shafeng Valley is accumulated by the number of days, which means that Chen Yu only practiced in the Shafeng Valley for fifteen days this month, and the remaining fifteen days can be left for the next month.

The barrier was open, and a black wind gustled towards him.

The deeper you go, the stronger this biting evil aura will be, and even the vision will be greatly hindered.

The inside of the Shafeng Valley was extremely large. As we moved forward, Chen Yu also saw blurred figures of other students.
