When Yi Feng got closer, he found that a thick layer of dust had fallen on this shelf, and it seemed that no one had touched it for a long time.

There was also a layer of dust on the jade tube, but its color could still be seen clearly, and the pitch-black color gave people a deep feeling.

But if you take a closer look, this jade cylinder seems to be ordinary again, and the strange fluctuations he felt just now have also disappeared, which makes Yi Feng even more curious, and he reached out and grabbed the pitch-black jade cylinder.

Bai Xi on the side stopped and said, "Yi Feng, you'd better not touch it, this exercise is very dangerous!"

Yi Feng's hand stopped in mid-air, he looked at Bai Xi, although the light was dim, Yi Feng still noticed Bai Xi's dignified pretty face.

"How dangerous is this exercise?"

"This exercise is called Lei Ling Jue, and the specific level is unknown, but it is quite dangerous to cultivate, so I threw it here. Jiang Lao didn't know when he appeared next to the shelf and explained to Yi Feng.

Yi Feng frowned slightly, Jiang Lao's words made Yi Feng's interest in this exercise a little stronger, after cultivating the Ethereal Technique, Yi Feng always had such a concept in his mind, the more dangerous the exercise, the more powerful it was to cultivate.

At the beginning, the cultivation conditions of the Ethereal Technique were also quite harsh, if it weren't for a coincidence, he would not have met the conditions, but unfortunately, there were some problems with the Ethereal Technique.

Yi Feng sighed secretly, if he wanted to find the true ethereal technique, he was afraid that it was far away.

Gathering his mind, Yi Feng focused his attention on the pitch-black jade cylinder again.

"I'll choose this Thunder Spirit Technique!" Yi Feng had a faint feeling that this exercise seemed to be not simple.

Bai Xiqiao's face was solemn, and he said: "Yi Feng, you have to think about it, there are people who have cultivated the Thunder Spirit Technique before, but when they were all attracting the Heavenly Thunder into their bodies, they were cut off by the destructive power of the Heavenly Thunder. ”

"What! Need to induce the Heavenly Thunder into the body?" Yi Feng was shocked, what kind of exercise was this, it actually needed the power of the Heavenly Thunder.

"That's true, absorbing the heavenly thunder is naturally dangerous, but if it is successful, the power is naturally strong. Jiang Lao said slowly.

"No, Yi Feng, if you change an exercise, your second sister won't let you do it!" Bai Xi also clearly remembered that six years ago, she was still a student in the outer courtyard, and the senior who was the first on the list of strong cultivators cultivated the Thunder Spirit Technique, and when she triggered the Heavenly Thunder, she was directly blurred by the flesh and blood of the Heavenly Thunder, and her death was extremely ugly.

"Okay, I'll choose it!" Yi Feng grabbed the Lei Ling Jue in his hand.

Bai Xiliu's eyebrows were upside down, and he said sharply: "Yi Feng, do you want to die?"

Yi Feng was a little stunned when he saw Bai Xi angry, and immediately said: "Sister Bai Xi, don't worry, I value my life more than anyone else, I won't joke with my life, if I can't do anything, I won't force it." ”

Bai Xi stared at Yi Feng but was a little helpless, this young man was unusually stubborn.

"Girl, don't worry, this little guy will be fine!" said Jiang Lao on the side.

Jiang Lao's words made Bai Xi and Yi Feng both stunned, and looking at Jiang Lao's appearance, they seemed to be quite determined.

Jiang Lao smiled mysteriously, raised his palm slightly, and suddenly, the silver-white spiritual power shuttled between his fingers like real lightning, and there was a faint sound of thunder, and the entire Spirit Jue Pavilion seemed to be filled with the domineering sense of thunder and lightning.

"Lei Lingjue, Jiang Lao has also cultivated?" Yi Fengyan said.

Jiang Lao shook his head slightly, and said, "It's just that the initial induction of the heavenly thunder into the body almost killed me, and I didn't even reach the entrance." ”

Yi Feng's expectations for Lei Lingjue were even higher, Jiang Lao didn't even get started, his spiritual power was so domineering, if his cultivation was successful, how powerful should it be?

Bai Xi looked at the two figures, one old and one young, shook his head and sighed, this is simply two crazy people.

After Yi Feng took the Thunder Spirit Recipe to the door to register, he left the Spirit Recipe Pavilion, because Yi Feng chose the Thunder Spirit Technique, so Jiang Lao didn't let him choose the martial arts again, but Yi Feng complained, but Jiang Lao ignored him. Yi Feng had no choice but to sigh helplessly, it was already an unexpected joy to get the Lei Ling Jue, and the discomfort in his heart quickly disappeared.

Yi Feng walked out of the Lingjue Pavilion not far away, suddenly his body shook, and immediately looked back at the door of the Lingjue Pavilion, Jiang Lao was smiling at him, Yi Feng also smiled lightly, nodded slightly, and then followed Bai Xi.

On the way back, Yi Feng asked Bai Xi to help hide his cultivation of the Thunder Spirit Technique, he didn't want his second sister Yi Fei to worry.

Bai Xi said with a straight face: "Who cares about you!" said, speeding up his pace.

Yi Feng shrugged helplessly, this woman is really holding a grudge, didn't she just listen to her advice and chose Lei Lingjue?

Yi Feng didn't follow Bai Xi back to Yi Fei's courtyard, but went directly to Jingyu, and when Yi Feng appeared in the boys' dormitory area, it undoubtedly caused some commotion.

After a period of recuperation, the wounds of the fat boy were almost healed, and the bruises on his round face were not visible.

When he saw Yi Feng in the boys' area, he immediately stopped in front of Yi Feng and said viciously: "Yi Feng! In three days, you will be unlucky!"

Yi Feng smiled, his dark eyes stared at the fat boy, and said, "What's the matter? Your skin is tight again today, and you want me to loosen it for you?"

The fat boy's neck shrank, and his body couldn't help but take a few steps back, Yi Feng beat him seven days ago, he was really scared, after that martial arts incident, the fat boy simply fell into the laughing stock of others' mouths.

"Yi Yifeng, you can't be arrogant for a few days!" The fat boy's voice was a little lustful.

Yi Feng was too lazy to continue to entangle with the fat boy, he was still in a hurry to go back.

He walked around the fat boy and walked towards Jingyu's courtyard.

"Yi Feng, in three days, don't be a turtle with a shrunken head!" a slightly sarcastic voice came from the side.

Following the voice, he saw Tian Ling staring at Yi Feng with a cold face.

"I'm afraid you'll shrink into your shell and refuse to come out!" Yi Feng also sneered.

Yi Feng came to Jing Yu's small courtyard, but no one was there, Jing Yu was afraid that he was being trained by the dean to be a devil.

Yi Feng was also happy and clean, and rushed into the room that Jingyu had prepared for him.

After adjusting his state, Yi Feng sat cross-legged on the bed and took out the pitch-black jade tube.

Sticking the jade cylinder on his forehead, the pitch-black jade cylinder seemed to flicker, and then, Yi Feng felt that there was a lot of information in his mind, and the obscure words made Yi Feng feel dizzy.

Fortunately, Yi Feng's soul power was strong, and this feeling only lasted for a few breaths before disappearing.

About five minutes later, Yi Feng slowly opened his eyes, and the information of the jade tube had been imprinted in his mind.

Yi Feng fell into a short groan, and then smiled helplessly, although Yi Feng's cultivation was not strong, but some of his knowledge and vision were not what they used to be, he could feel that this Thunder Spirit Technique should also be a mutilated exercise, and the last words seemed to have been cut off by someone.

"It seems that this exercise can only support my cultivation to the Earth Spirit Realm. But this also made Yi Feng quite satisfied.

Yi Feng knew that being ambitious was not a good phenomenon!

After figuring out some of the matters that needed attention in the cultivation of Lei Lingjue, Yi Feng no longer hesitated, put his hands together in front of his chest, and entered the cultivation state. His breathing gradually showed a sense of regularity.

The cultivation of this remnant thunder spirit recipe is divided into two parts, first of all, it is necessary to transform the spiritual power in the body into thunder attributes, and after the spiritual power in the body is completely transformed into thunder attributes, it is the most dangerous time, and it is necessary to attract the heavenly thunder into the body.

After cultivating that ethereal spirit technique, Yi Feng understood this thunder spirit technique quite easily, and soon, a trace of thunder attribute spiritual power appeared in Yi Feng's body.

A trace of silver-white appeared in the emerald green spiritual power in the veins, and Yi Feng's body seemed to have a thunderous sound.

Yi Feng was overjoyed in his heart, and he didn't hesitate, he quickly ran the Thunder Spirit Technique, wanting to transform the spiritual power in his body in one go.

There was more and more silver-white spiritual power in Yi Feng's veins, and Yi Feng's body thundered.

This kind of cultivation lasted until the evening, and half of the spiritual power in Yi Feng's body had already been transformed into thunder attributes.

As the transformation progressed, Yi Feng's rather calm face gradually became solemn, and his brows were also tightened, because he found that when half of his spiritual power was transformed into a thunder attribute, it was difficult to refine the emerald green spiritual power in the slightest.

Yi Feng used the Thunder Spirit Jue to the extreme, and fine beads of sweat overflowed from his forehead, but it was still to no avail.

At this time, the spiritual power in Yi Feng's body was half silver and half emerald green, and the two spiritual powers were intertwined with each other.

The forces of life and destruction are counterbalanced against each other.

Yi Feng smiled bitterly, he couldn't explain this situation, and he didn't even know if it was good or bad.

"It's really a problem!" Yi Feng smiled bitterly and ended his cultivation.

He jumped off the bed, stretched out his palm, and the spiritual power surged, the gray-green spiritual power was like a flexible little snake, shuttling between his fingers, Yi Feng knew that this was the product of the mixture of the two spiritual powers.

"Hopefully there won't be any major problems. "There is no problem for the time being, so that Yi Feng can rest assured a little.

"Yi Feng, you come out for me!"

In Yi Feng's deep groaning, a coquettish cheer came from the courtyard.

Yi Feng immediately recognized the owner of the voice, which was Bai Xi who took him to the Spirit Recipe Pavilion in the morning.

Yi Feng scratched his head a little sneeringly, he promised Bai Xi to attend classes honestly from now on, but when he cultivated, he forgot the time.

"Sister Bai Xi, why did you find here?" As he spoke, Yi Feng walked out of the room.

Bai Xi was even more angry when he saw Yi Feng with a smile on his face, Yi Feng was still the first student in the outer courtyard who promised her and didn't do it, Bai Xi felt that he should teach Yi Feng some lessons.

Bai Xi said with a straight face: "Don't pretend to be stupid with me, you said okay to go to class, what about you?"

Yi Feng smiled bitterly, sure enough, because of this incident, his face became unnatural, and he scratched his head and said, "That, I have cultivated and forgotten the time!"

"Hmph, it seems that if I don't teach you a lesson, you won't know how strict I am, the teacher of the outer courtyard!" As he spoke, Bai Xi's spiritual power quietly surged, and the blue spiritual power on Qianqianyu's hand rose up, and the momentum of the Xuan Ling Realm burst out, looking at Bai Xi's appearance, it seemed that he was not ready to show mercy to Yi Feng's subordinates.

Yi Feng was a little stunned, this was really a disagreement and he started to move, but Yi Feng did not flinch, his eyes burned with fighting intent!

"Just try the power of this spiritual power. Yi Feng bent his knees, his body swept out, his fists clenched, and the gray-green spiritual power quickly wound up.

Bai Xi was even more annoyed when he saw that Yi Feng didn't know how to admit his mistake, but instead shot at her.

"Yi Feng, today I will teach you how to respect the teacher!"
