Sima Yunfei didn't say a word, just quietly followed Dugu Yu into the cave.

Both of them were silent, and the atmosphere was a little awkward.

"Master, the apprentice knows that he is wrong, and I promise that nothing like this will happen again in the future. After a long time, Sima Yunfei once again took the initiative to admit his mistake.

"You can think like this, it's best, I don't want to see you like this again, if there is, you will no longer be my apprentice, people, you must be calm, have enough connotation and cultivation, in order to go further, this world, there is no lack of genius, but there is a lack of that kind of thoughtful, cultivated, moral cultivator, if you can't suppress your emotions, it will be easy to lose your mind in the future, go mad, and enter the demon path, do you understand?" Dugu Yu said a lot in a serious voice.

"Apprentice knows, master. Sima Yunfei bowed his head and replied.

"Okay, you have broken through to the True Dao Mirror cultivation, congratulations, there is nothing worth giving to you as a teacher, then teach you a set of peerless martial arts, this set of martial arts was also given to me by others, you must not leak it, otherwise I will break you into thousands of pieces, do you understand?" Dugu Yu said extremely sternly.

The apprentice wrote it down. Sima Yunfei replied with a heavy expression.

"This martial art is called stealth trick, it is a kind of martial art that can hide the body, the first layer of practice, you can see your body fused into the air, the second layer of practice, you can carry out physical attacks, as for the back, you will dig slowly by yourself in the future, remember, this martial art is not a last resort, can not be used. Dugu Yu instructed again.

"Yes, master. Sima Yunfei took the cheats and memorized them carefully.

After a while, Sima Yunfei memorized the mantra of the stealth recipe by heart.

Dugu Yu told Sima Yunfei all his cultivation experience before leaving the cave.

"Four months later, I'll come back to you, you can cultivate well!" Dugu Yu's voice had not fallen, and the person had already disappeared into the air.

In fact, there was no need for Dugu Yu to teach Sima Yunfei a lesson just now, but for the sake of Sima Yunfei's future development prospects, he had to ask for strictness.

Seeing that Dugu Yu had taught him all the tricks of invisibility, Sima Yunfei was extremely happy in his heart and began to taste it seriously.

The martial art of stealth seems to be of little use, but in fact, it is extremely useful in actual combat.

Moreover, if you cultivate to a high level, you can also carry out physical attacks.

It can be said that the stealth trick is a supreme martial art that is both offensive and defensive.

Four months passed in a flash.

In the Xuancheng Mountain Range, in the dense forest, in a secluded cave, Sima Yunfei closed his eyes tightly, and his whole body exuded a wave of power, surrounding the entire cave.

Suddenly, Sima Yunfei's body suddenly disappeared and melted into the air.

When Sima Yunfei reappeared, he was already a mile away from the cave.

"I have finally succeeded in cultivating the first layer of the Stealth Technique. Sima Yunfei's expression was full of a smile, and he was extremely happy in his heart.

It took Sima Yunfei two months to successfully cultivate the first layer of the invisibility technique, which shows how difficult it is to cultivate this stealth technique.

But compared to Dugu Yu, Sima Yunfei's cultivation speed was indeed too slow, and it only took Dugu Yu three days to successfully cultivate the first layer of the invisibility technique.

However, at that time, Dugu Yu had the help of the mysterious Rubik's Cube, so he was able to cultivate successfully at such a speed.

Although Sima Yunfei can't be compared with Dugu Yu, compared to ordinary geniuses, his speed is fast enough, and it takes others half a year to cultivate, but he only takes two months, which also shows that his cultivation talent is amazing enough.

In the past four months, Sima Yunfei has also cultivated another ground-level beginner-level martial art, the Broken Mind Sword.

This set of martial arts is one of the unique martial arts of Sima Yunfei's father, Sima Xiaotian, Sima Yunfei has long had this set of martial arts, but his previous cultivation was too low to cultivate.

Since he broke through the initial cultivation of the True Dao Mirror, and can cultivate, there are a total of three styles of the Broken Mind Sword, and Sima Yunfei has successfully cultivated the first style, and he has also fused the sword strength.

In the past four months, Sima Yunfei has advanced by leaps and bounds, and his sword strength has also broken through to the third layer, which can be described as an all-round progress, and the initial cultivation of the True Dao Mirror has also been stabilized.

"With my current strength, what kind of ranking can I achieve on top of the genius battle?" Sima Yunfei thought to himself, looking into the distance with a somewhat empty look.

The stealth technique has been practiced to the first layer, the broken sword has been practiced to the first style, the sword strength has broken through to the third layer, the Canglong sword technique and the Ten Thousand Swords Guizong have all been refined to the Great Perfection, and the sword strength has been integrated into various martial arts, and the strength is not strong, but Sima Yunfei knows very well in his heart that the people above the genius battle are not mortals, even if he has so many martial arts and his cultivation has broken through, but he still has no bottom in his heart.

"I don't know what the master's current cultivation situation is, he said that as long as I break through, he will appear, but the master has not appeared so far, has he traveled far away?" Sima Yunfei thought to himself in his heart, preparing to fly into the cave, waiting for Dugu Yu's arrival.

However, at this moment, about 10,000 meters away from Sima Yunfei, a breath of death gushed out, rolling in, and the momentum was so great that he had never seen it.

"Is this, the breath of death?" Sima Yunfei couldn't help but tremble as he spoke, no, his body was trembling.

Because the scene he saw was too terrifying, and the intensity and quantity of the breath of death were unprecedented.

"To what extent has the master's ghost destroying magic technique been practiced, how can there be such a big movement?" Sima Yunfei couldn't help but fantasize.

At this moment, the surrounding animals were fleeing in all directions, and these animals were frightened as if they had seen death, and they desperately ran away from the mountains.

As the rich aura of death qi continued to grow, with Dugu Yu as the center, all the death qi in a radius of one mile around him gathered on his body, and it was pitch black, and he couldn't see the south, south, west, and northwest at all.

With a "boom" and an explosion, the surrounding dense forests and hills were all razed to the ground, and dust flew into the sky, accompanied by the breath of death.

A laser flashed, and Dugu Yu soared into the sky, standing proudly in the air, incomparably majestic.

Looking at Dugu Yu in the distance, like a great hero of the world, making people bow and worship, Sima Yunfei actually had a feeling of seeing a god in his heart.

"Master's aura is so powerful. Sima Yunfei couldn't help but sigh in his heart.

Although Dugu Yu never said a word from beginning to end, he has an irresistible charm, which is not seen in the current Sima Yunfei.

"This is the strong man, not angry and self-prestigious, which makes people extremely respectful, master, I also want to become a strong man like you. Sima Yunfei looked at Dugu Yu, looking at his master with a pair of eyes adoringly, and secretly wanted to make up his mind in his heart.
