Night has fallen, and the climate in the mountains is a little cold.

Wang Meng's temporary villa is located halfway up the mountain, overlooking the view down the mountain through the bright windows on the second floor.

After a simple dinner, Wang Meng was about to meditate and cultivate, but was unexpectedly stopped by the ghost solemnly.

"Sister Ghost, what's the matter?" After getting along for so long, Wang Meng could see that there must be something in the ghost's heart.

Looking at the night outside the window, the ghost was silent for a while before he spoke: "Wait a minute, I'm going to teach you how to convert true qi into a special caste!" ”

As soon as he opened his mouth, Wang Meng was shocked, and the ghost had mentioned that the true qi was converted into a special caste, just like Ru Xue's true qi had an ice surname.

To Wang Meng's surprise, he didn't expect the ghost to teach him so quickly, originally meaning that it would take another year and a half before he was qualified to learn!

"There are many kinds of true qi castes, each of which has its own characteristics, and I hope you will choose a major surname before you formally study it." The ghost looked serious.

"Sister Ghost, is there a major and elective for changing the caste?" Wang Meng suddenly thought of college life, and the courses he studied were divided into majors and electives.

"That's right, normally speaking, a person can major in one, and taking one is already considered a lot of qualifications." The ghost said and glanced at Wang Meng with a strange look, and then continued, "But you are an outlier, as long as you determine the major surname, everything else can be used as an elective." ”

"Sister Ghost, what are the different types of surnames, and what are the characteristics of each?" Before deciding, Wang Meng wanted to understand it clearly, so as not to regret it later.

"They are: fire, water, earth, wind, light, and dark!"

"Each caste shows different characteristics, and the fire caste is mainly manifested by burning and blasting; The water surname is mainly manifested as agile and frozen; The native surname is mainly characterized by hardness and strength; The wind surname is mainly manifested by chopping and speed; The light surname is mainly manifested as lightning and endowment; And the dark caste is mainly manifested in devouring and destruction! ”

The ghost said a lot in a row, but Wang Meng could only understand a rough idea.

"Sister Ghost, what kind of caste are you majoring in?" Wang Meng suddenly came up with such a question.

"I major in the fire surname, and elect the wind surname and the earth surname!" The ghost said with a flat face.

"Then I'll also major in the fire genus surname!" Wang Meng replied simply.

The ghost shook his head lightly: "Everyone has their own characteristics, you can't blindly follow me!" ”

Seeing Wang Meng's embarrassed expression, the ghost hesitated for a moment, and finally said, "In your case, the secret surname is the most suitable for you!" ”

Wang suddenly raised his head and looked at the ghost with some puzzlement.

"Whether it's your anti-dragon body or the anti-dragon pattern on your body, it is very consistent with the dark surname." When the ghost said this, he turned his words around, and said, "However, although the dark surname is powerful, its cultivation difficulty and danger coefficient are also the largest among the several genus surnames!" ”

"For the caste 'dark', if you can't control it, it will control you!" The ghost added.

Wang Meng was silent, he was now faced with a choice, a choice about his future cultivation path.

Time passed little by little, and the ghost did not speak again, she was waiting for Wang Meng's reply. At this time, she wanted to leave the power of choice to Wang Meng.

"Sister Ghost, I've thought about it," Wang Meng suddenly raised his head, there was no confusion in his eyes, "I'll major in the Dark Surname!" ”

"Have you decided?" The ghost stared straight at Wang Meng, "The dark surname is extremely difficult to control, and I don't decide whether there will be a backlash, I hope you think about it carefully!" ”

"I've thought it through, so I'm going to major in the Dark Surname!" Wang Meng smiled faintly, "Sister Ghost, didn't you say that I am the body of the anti-dragon, since I have the ability to defy the sky, why am I still afraid!" ”

Staring at Wang Meng's resolute face for a long time, the ghost suddenly burst out laughing: "Okay, it is worthy of the person I fancy, and he has courage!" ”

The ghost didn't make the same decision as Wang Meng, knowing that entering the "Purgatory Nine-Story Tower" might be dangerous, but she resolutely decided to take a risk to find out.

In order to grasp the time, while the moon was bright, the ghost began to teach Wang Meng the exercises of caste transformation.

After a night of hard work, Wang Meng finally succeeded in learning how to convert the qi in his body into a dark surname.

Looking at the true qi in his hand like black gas, Wang Meng's heart was very excited, he could feel that this kind of secret surname true qi contained extremely terrifying destructive power, like a ferocious beast trying to break free from his palm.

"It's just that it's so difficult to control after transforming such a point, it seems that what Sister Ghost said is true, and this kind of dark surname is really difficult to master."

In order to test the difference between this secret surname and the previous true qi, Wang Meng found two boulders of similar size. First, with the palm of his previous True Qi, the boulder immediately shattered into countless pieces.

"Now let me see what the difference is with this secret surname, right?" Thinking so in his heart, Wang Meng put the transformed Secret Surname True Qi on the palm of his hand and struck it towards another boulder with the same force.

There was a sound of "poof", and Wang Meng's entire arm actually penetrated the boulder directly.

"This ...... This is the power of the Dark Caste? Pulling out his arm, Wang Meng looked at the hole on the boulder that had been punched out by himself with a blank expression.

At this moment, Wang Meng could feel that there was still a remnant of the dark surname around the cave.

In curiosity, Wang Meng stretched out his hand and rubbed around the smooth hole, and as soon as his fingertips touched, a large piece of stone chips slipped down, like dust after being completely burned.

"This ...... So domineering? ”

Wang Meng was dumbfounded again, he could imagine that if this palm was hit on a person, it would definitely make the other party die cleanly and completely.

"I can't give you much advice for this kind of secret caste, if you want to fully control it, you need to explore it yourself." The ghost said to Wang Meng, who was still stunned.

Wang Meng nodded.

"I only have a set of secrets here that are suitable for the secret surname, I can't remember its origin, and I haven't verified the real surname of the content, and now I will teach it to you, whether to practice or not depends entirely on you!" The ghost's brow furrowed as he said this, as if he was struggling to remember something.

Soon Wang Meng knew that the set of secrets that the ghost said was suitable for the secret surname - Demon Devouring Yin and Yang Formula!

What surprised Wang Meng was the length of this set of secrets and the all-encompassing content......
