The good intentions of the management elders, Thunder Blade naturally understood. However, when he chose these two cheats, he was already prepared in his heart, and no matter how hard and dangerous it was, he would not give up!

"Elder, thank you for your kind reminder, I see. However, I'm sorry to sign up, I've already decided, so I'll borrow these two cheats. Thunderblade said politely.

"You're a ...... Alas! ”

Seeing that Thunder Blade did not listen to dissuasion, the management elder frowned and kept shaking his head. Since Lei Jian insisted, he had no choice but to record truthfully: "Remember, the period for borrowing books is three months, and the books will be returned after three months." If you want to renew the loan, you must also repay it within three months, if it is more than one day, it will be disposed of according to the door rules! ”

"Hmm."

"Thunder Blade, I'll say one more thing, "Jiuding Divine Skill" is good, this "Heaven and Earth Domineering Formula", dangerous and abnormal, if you don't believe my words to practice, remember, you must start cultivating from the introductory chapter, once you feel that it is difficult to cultivate, don't stick to it, hurry up and come to me to change the book, remember, life matters, don't be persistent."

"Thank you Elder for reminding me, I remember."

Taking the two cheats from the management elder, Thunderblade turned around and slowly left.

"Alas, young people nowadays!"

Looking at the back of the Thunder Blade leaving, the management elder couldn't help but shake his head and sigh, and muttered, "I bet that within three days, he will definitely return the Heaven and Earth Domineering Technique!" When the time comes, see how much of his stubborn temper is left today......"

……

"Why did you borrow these two cheats?" When Mu Qingyan saw the two cheats that Lei Blade had borrowed back, although Lei Blade couldn't see her expression behind the veil clearly, he could guess that it was mostly the same surprised expression as the managing elder of the classic room.

Lei Jian said: "I have chosen for a long time, and I think these two cheats are suitable for me. You don't care, I chose them, and I have my own reasons for choosing them. ”

"You have a big tone, I can ignore this "Jiuding Divine Skill", but this "Heaven and Earth Domineering Technique", you must return it." Mu Qingyan said in an unquestionable tone, "When I first came to the Qingzhu Sect a while ago, the head of the sect had a plan to list some evil sect cultivation techniques of the Qingzhu Sect as a forbidden book for the disciples of the Qingzhu Sect to cultivate, and this "Heaven and Earth Domineering Formula" bore the brunt. You are only a cultivator in the early stage of Qi refining, and you have just started for more than two months, and if you want to cultivate the Heaven and Earth Domineering Technique, it is simply a matter of death! ”

"How do you know if you don't try, but you will know if you try." Thunder Blade said lightly.

"Can you try this kind of cultivation technique that is very easy to go mad? Do you really care about your life? ”

"Do you care about my life?"

"I ...... Your current life is not only yours, but also the Qingzhu faction. I am entrusted by the head of the house, and I am naturally responsible for your life. ”

Mu Qingyan was stunned for a moment in the face of Lei Blade's rhetorical question, and then explained with some stumbling words.

Thunder Blade could see that she was a little shy just now, and said with a smile: "Then you just say that you are responsible for me." ”

"You! You are not allowed to speak to me in such a frivolous tone! ”

This time, Mu Qingyan was really angry, "Your life is also mine now." Now, you immediately return the Heaven and Earth Domineering Formula. Do you know that when the head of the sect was still young, he also practiced the "Heaven and Earth Domineering Technique", and after more than ten years, he almost went mad several times, but he only cultivated to the second layer, and now, he only has the strength of the third layer. After decades of time, he only cultivated to the third layer, and he almost took his life. Even the head of the sect has now given up cultivation, how do you compare with the head of the sect? ”

"Naturally, it's better to be in charge." Lei Jian heard that the head of the sect was also a genius of cultivation, which made countless people envy and revere.

"That ......"

"However, I still have to cultivate the Heaven and Earth Domineering Technique, this is my decision."

Without waiting for Mu Qingyan to speak, Lei Jian took the two cheats and left directly.

"Thunderblade! You, you...... You're so annoying! ”

After the thunder blade was gone, Mu Qingyan stomped his feet angrily. It's just that at this moment, no one saw it.

"I don't believe it yet, this book eats people!"

The more he was dissuaded by the management elder and Mu Qingyan, the more angry Lei Jian felt in his heart, and Lao Tzu had to practice the "Heaven and Earth Domineering Technique" well!

Just do it, and for the next few days, Thunderblade completely entered a state of retreat.

He put "Jiuding Divine Skill" aside and devoted himself to cultivating "Heaven and Earth Domineering Technique".

According to the advice of the managing elder, he first memorized the mantra of the introductory chapter, and then he meditated and practiced day after day on a boulder in the back mountain.

In this introductory chapter, the emphasis is on calming the mind and calming the qi, distinguishing the yin and yang qi between heaven and earth, and then, trying to use one's own true qi to guide the yin and yang qi between heaven and earth into the body, and refining it into the so-called "domineering" in "Heaven and Earth Domineering Formula".

The so-called domineering qi is a domineering qi, which is refined from the yin and yang qi of heaven and earth, and its power is unmatched. This is also the origin of the name of "Heaven and Earth Domineering Jue".

"Heaven and Earth Domineering Qi Recipe can only be cultivated by men, so it is usually cultivated and absorbed, and it is all yin qi. The yin qi at night is extremely strong, which is definitely convenient for me to cultivate. ”

Five days had passed, and the Thunder Blade had mastered the method of absorbing Yin Qi, but it had found nothing. After thinking about it carefully, he changed the cultivation time to twelve o'clock in the evening.

At this time, there was no moon in the sky, and in a group of pitch-black red, Thunderblade sat in the shrubs in the back mountain bamboo forest, and his mind was united and he forgot himself.

Inside the bamboo forest, the cold air lingers, and the temperature drops at night, and the fog condenses into dew.

"Huh?"

And in the mist of the bamboo forest at night, as soon as the Thunder Blade True Qi was released, his keen perception was aware that in this bamboo forest, the night yin qi was extremely heavy.

Seizing the opportunity, the Thunder Blade hurriedly urged the mantra, held his breath and concentrated, and slowly absorbed the cold qi of the surrounding Yin into his body.

"Lean ......"

When a trace of cold yin qi penetrated into the body of the thunder blade, the thunder blade suddenly shuddered, and then, the body twitched violently, and he felt the strange birth in his body!

The original yang qi and true qi in his body are quite abundant, and at this time, the yin qi enters the dantian, due to the conflict of yin and yang, violent fluctuations occur, and the table xiàn is on the body of the thunder blade, the body of the thunder blade twitches and trembles, and then the cold feeling spreads throughout the body!

The yin qi that entered the body, because of the resistance of the original aura in the dantian, was actually rebounded out!

A stream of coldness spread to every inch of the skin of the body in an instant, making the thunder blade break out in a cold sweat, and the whole body was agitated.

"It is said that "Heaven and Earth Domineering Formula" is both good and evil is a forbidden book for cultivation, Lao Tzu can be regarded as a master today, this cold yin qi, drilling heartache, now with my strength, it is difficult to discharge it from the body...... Damn, the yin qi eats the body, could it be that Lao Tzu has only been practicing for a few days and then gone mad?! ”
