Xu Dong was stunned inexplicably, he didn't expect this story to have such twists and turns.

"The exercises recorded in this immortal book are yin and yang fire, and this exercise is divided into forty sections, and only five sections are recorded in each volume......"

Xu Dong was so shocked that he couldn't close it for a long time.

"This group of people is exactly seven, and our seven sisters visited these seven people in order to avenge their families, and each followed one person to find an opportunity to kill them. ”

Xu Dong said, "Kill, you are all weak women, can you kill them?"

"We don't have much ability, but we can borrow other people's hands to eradicate them, this is a woman's scheming. ”

"Borrow someone else's hand?"

"Yes, for example, I can borrow your hand and kill Fang Wei. ”

Xu Dong smiled bitterly, "I?killed Fang Wei?You are laughing, how can I have this ability?I have been killed by him once!"

"Your ability is not innate, but your ability is really natural, your parents give you an extreme yang body......"

Xu Dong was taken aback, "How come you even know this?"

"Isn't this simple? The beginning of "Yin and Yang Fire" talks about the extreme yin and yang. ”

"Alas!" the red-line girl sighed, "It's a pity that I'm not an extreme yin body, if I were worthy of you, I would be a couple with you for a thousand years and be a fairy couple." ”

Xu Dong said in his heart, seeing that your red-line girl is as beautiful as a fairy, needless to say, I, Xu Dong, am also willing.

"However, Fang Wei is higher than I have more than one realm, and I have practiced yin and yang fire, how can I kill if I want to?"

"Dizzy! Didn't I say that there are forty stages of yin and yang fire? The one in their hands is only five paragraphs, and the worse thing is that there are only five paragraphs in the world. ”

"You're saying they don't know that there is a higher rank in this exercise?"

"yes, isn't that a fatal wound for them?"

"There are eight volumes of Yin and Yang Fire, and they robbed the first volume, but what about the other seven volumes?

"Giggle!" the red-line girl turned around and smiled like a silver bell.

"Is my dad so scheming? He put the other seven volumes on each of our sisters, and each of the seven sisters had one of them. ”

As she spoke, she took off a light green jade ring from the ring finger of her right hand and handed it to Xu Dong.

"There is the second volume of Yin and Yang Fire in this ring, that is to say, according to this, you can practice to the tenth stage of Yin and Yang Fire. ”

"Then the first volume is not, isn't it necessary to cross the first to fifth paragraphs, and start practicing from the sixth paragraph?"

"Look at what you said, any volume can be crossed, but the first volume can't, it's the foundation of the foundation, and you can't practice the later ones without it. ”

"Didn't this first volume fall into their hands?"

"You underestimated my father again, he copied seven copies of the contents of the first volume, and each of our seven sisters had one copy on him. ”

Xu Dong finally figured it out, Yu Laoguo, the father of the red-line girl, was wary of someone robbing the immortal book, and he had already laid an ambush.

How deep is this ambush! He has seven mechanisms, and any one of them can kill the enemy.

"Aren't you afraid that after I take your ring, I won't take revenge on you and leave?"

Xu Dong picked up the light green jade ring and put it on his left ring finger.

"Don't be afraid, Fang Wei also has a murderous vendetta with you, how can you not take revenge on yourself?"

Xu Dong smiled, "This is what you said right, if you have revenge, you are not a gentleman!"

When the red-line girl sent him out of the cave, she told him that if there was anything going on, he could come here at any time to find her.

Out of the cave to a mountain pass, see a broken wall chiseled with the word "Taiwu Mountain", only to know that this is 5,000 miles away from the lotus hole.

No matter how far he went, he couldn't withstand his half-day divine journey, and in the evening, he arrived at the barren meadow.

Along the way, he had already thought of two strategies against Fang Wei.

First, he didn't show up for more than two months, and he couldn't let Fang Wei know that he Xu Dong was still alive.

Second, he stepped up his cultivation of Yin and Yang Fire, striving to practice to the second stage during this period, and he estimated that Fang Wei had only practiced to the second stage.

At the edge of the barren meadow, seeing the house he built for Yaqian, seeing things and thinking about people, I couldn't help but feel sad.

Yaqian doesn't know where she is now?

Thinking that Yaqian might suffer a lot, he was even more heartbroken.

Yin and Yang Fire, everything is the fault of the fucking Yin and Yang Fire.

If you want to compete with Fang Wei, you must practice yin and yang fire.

If you want to rescue Yaqian as soon as possible, you must also practice yin and yang fire.

Yes, if his Yin Yang Fire is practiced a few levels higher than others, all his demands can be realized.

Entering the Lotus Cave, Su Hong saw him with a leap of joy, and his arms climbed to his neck.

"Su Hong, are you okay?"

"Shaoxia, I'm fine, I'm just alone and lonely, people miss you so much!"

"It's okay, I'll go, I still have important business. ”

Su Hong pursed her mouth, "What's the matter again? In the past few days, I didn't expect people to be so lonely in the cave alone!"

"It's really something, you're playing alone now, I'll accompany you later, ah?"

"Okay, you're busy, I'll go take a bath first. ”

After Su Hong left, Xu Dong couldn't wait to take out the jade ring given to him by the red-line girl, and injected divine thoughts into it, and the jade ring glittered into an immortal book.

"Yin and Yang Fire, known as 'Extreme Fire', 'Extreme Fire', the Spirit of Fire ......"

"This skill takes the yin and yang true fire in the human body, synthesizes the 'extreme fire' to melt gold and break iron, and burn all things. ”

The book also explains in detail the conditions, requirements, and key points of practicing yin and yang fire.

The basic condition for practicing yin and yang fire is that only "extreme yang" men can practice this skill, and there must be "extreme yin" women to match.

After satisfying this condition, it is also required to be assisted by elixir, and about 300 kinds of high-grade medicinal stones are required, which is a material condition.

The practice of yin and yang fire is divided into five stages: cultivation, trial, fire resistance, metallurgy, and synthesis, and each stage takes two to three months.

There are also a few important points to keep in mind, the most important of which is that the practitioner should be calm and not rush to attack the heart.

In addition, the most important thing is to observe the body with internal vision, and always pay attention to the balance of yin and yang in the body.

In fact, this is what all practitioners of the Inner Dan Dharma should pay attention to, because once the balance of yin and yang is out of balance, not only will the exercises fail, but the human body will also be abolished.

It's just that you should pay more attention to this point when practicing yin and yang fire, otherwise it is easy to go mad.

Xu Dong read these words in the book, which was almost a blow to him, a disadvantage that shook his faith.

He was even a little discouraged, according to the book, it would take at least a year to practice Yin and Yang Fire.

And how could he have such ample time? More than two months later, he was going to participate in the Linggu Sect Outer Sect disciple competition.

If in the competition, he frustrated Fang Wei's disciples, Fang Wei might be angry and blatantly use yin and yang fire to kill him again.

If you don't practice, you will definitely not be able to do it, and you won't even have a chance to defeat Fang Wei.

Also, Yaqian is still in the hands of others, if he gives up practicing yin and yang fire, he may never save Yaqian.

"Practice!"

Xu Dong pondered for a long time and finally made up his mind.
