Storm Demon Sea, Sky God Island.

The Kongshen Island is not small, and its land area is not even as big as the Martial Arts in the Demon City.

Lu Yu's small villa is located in the center of the island, at the bottom of a stone pillar that holds the sky, with a relatively wide view.

And Lei Yi is now practicing the ideas taught by Lu Yu on Kongshen Island.

Lu Yu gave him three Taoist methods to cultivate the immortal world, namely "Golden Light of the Earth", "Come on the Clouds and Misty" and "Nine Breaths of Convincing Qi".

The first two, as the name suggests, are escape techniques, and are mostly used for escaping and rushing.

Lu Yu seemed to be able to see what Lei Yi was missing, which really solved his urgent need.

Lei Yi is good at close combat. Although he lacks long-range attack methods, this is not his way of fighting after all.

What he lacks is the way to fly and escape.

After practicing the golden light in the ground, the body turns into a golden light and escapes into the ground, and travels thousands of miles away. It is definitely a must-have way to save your life when traveling at home.

Flying the clouds and fog is an extremely fast method of flying in the air. It is the aura of a cultivator.

As for the nine breaths of breath, it is a breathing method.

However, this breathing method is amazing. It is a special breathing method created by a body-refining monk. By breathing and breathing nine breaths, you can absorb the innate qi and transform it into your own vitality, and restore your entire state.

After Lei Yi finished his practice, he tried it and the effect was indeed great.

Even if he can only complete the first breath of the foundation, his body's vitality will recover by 10%. If he completes nine breaths at the highest level, the caster can instantly recover 90% of his vitality in a short period of time.

However, this breathing method also has its disadvantages, and it requires the density of the heaven and earth energy in the whole body to be sufficient.

Because this is a domineering breathing method that sucks the vital energy of heaven and earth in a rough manner to suck it into the body. If the vital energy of the whole body is not even there, there is nothing we can do about it.

Fortunately, the density of the energy of the Demon Realm is much higher than that of the human Realm, and even compared with the Immortal Realm, it is completely in line with the conditions for performing nine breaths of convincing.

Now, Lei Yi is practicing.

The way Lu Yu gave him practice was to carry a stone mountain on his back and fly in the air.

According to Lu Yu's opinion, if you can fly with a mountain on your back, then you will fly faster without carrying a mountain on your back.

The same is true for practicing the golden light of the earth. If you run into the ground with a mountain on your back, if you run fast enough, then won’t it be faster if you don’t carry the mountain on your back?

Moreover, practicing on the back mountain can also achieve the effect of training physical strength. Lu Yu is worthy of being a researcher. He is even proficient in inscription formations and engraved countless runes on the stone mountain that Lei Yi carries.

These runes have no other functions, but can increase the weight of the mountain.

Next, someone fell into suffering and needed to fly hundreds of thousands of miles in the air every day, and then escape to the ground for hundreds of thousands of miles.

When you become tired, you have to recover through the Nine Breaths of Conquest Method, and then you cannot waste your boxing practice. When you finally meditate and regulate your breathing, your muscles in your body are bulging, which is simply hellish torture.

With Lei Yi's power, carrying a stone mountain is nothing, but the weight of this mountain is increasing every day.

However, Lei Yi did not give up because he felt that after he carried the weight every day, his physical strength was also increasing rapidly, and his own ability to withstand pressure was also increasing.

One day, Lei Yi came to Lu Yu with a stone mountain dozens of meters high.

"Senior Lu Yu, your rune power is activated to the limit. How much weight can the mountain increase?"

"If you consider the limit of Shitou Mountain and adjust the rune power to the maximum, the weight should be increased by 50 times on the current basis!" Lu Yu looked at Lei Yi, who was sweating and panting after walking on the back of the mountain, said lightly.

"Okay, in the future, I will definitely challenge the final difficulty and fight 50 times the current weight!"

Lei Yi was like taking a big tonic. He carried the stone mountain on his back before dawn, and then used the clouds and fog to fly out of the Kongshen Island.

In the evening, he crawled out of the ground with a slight sound, raised the stone mountain on his body, and started lifting weights and squats on the spot.

Rumble!

Finally, Shitou Mountain was thrown by him on Kongshen Island, smashing the ground near the coastline rumbled.

After doing these things, it was still at night. Lei Yi only started practicing boxing after nine breaths of conscience, until midnight with the stars, and then began to meditate and regulate his breathing and recover.

So much so that during this period of time, Night Sky Bell could only return home in disappointment every time he came to Lei Yi.

"Die Ergou, bad Ergou, you know how to practice and don't come to accompany me. You're so bored!" Every time this woman saw Lei Yi practicing, she could only sulk alone.

...

One month later.

Time came to early April, 2296, in the Chinese calendar.

Kongshen Island, on the beach by the sea.

"Oh, I finally arrived in a month, and I can go out to play again~"

“Yeah ~(?′ω`?)”

The night sky bell came here with Pangpang and cheering.

As for why they were so happy, it was naturally because Lei Yi promised to train on Kongshen Island for a month, and now the time has finally come.

In the sky, a figure rushed from the storm demon sea.

The figure stepped on the water and actually used the light skills of floating on the water, running wildly on the turbulent sea surface.

The difference is that this person actually carried a small stone mountain dozens of meters high on his back, and the surface of the mountain was engraved with countless complicated inscriptions, and all of them were lit.

"Ergou, Ergou, come on, come on!" Yekongling and Pangpang cheered while cheering for the people coming.

Of course, they do this so that they can go out and play. As for cheering each other up, they are all by the way.

The person who came was Lei Yi. Compared to a month ago, his aura became stronger. His skin turned brown due to training, and his muscles more than doubled, full of strength.

The stone mountain he carried behind him was lit up on all the inscriptions on the surface, and the weight reached its peak, which was 50 times stronger than a month.

But this increase was formed subtly in one month of training, and Lei Yi has become accustomed to it.

He stepped on huge waves and galloped for more than ten thousand miles, and finally landed on Kongshen Island.

"The one-month deadline has arrived, and this stone is useless!" Lei Yi threw the huge rock in his hand into the sky, then jumped high and punched.

Boom!

In a blast like thunder, the rock exploded, and huge air waves spread out, and the air shook accordingly.

The boulder shattered into powder, and the runes on the surface fell off and disappeared with the wind, which also indicates that the boulder had completed its mission.

After landing, Lei Yi immediately ran his nine breaths and accepted his breath. During the nine deep breaths, his chest was swelling and roaring endlessly, like thunder, making his eardrum tremble.

After nine breaths, an incredible scene appeared.

Lei Yi's explosion-like muscles began to slowly contract, and his figure became relatively even from the original full of power.

After a while, he became a young man with an ordinary appearance and an ordinary figure, but his skin color was a little tanned during the last month of training.

Lei Yi clenched his fists and swung it casually. In the air around him, with his physical strength, the air flowed and the wind stormed, bringing up a stream of sand and dust.

"My strength has increased by at least ten times more than a month ago, and my endurance, physical fitness and stress resistance have increased to a level that I don't even know the limits!"

He is now full of confidence. As long as he does not meet a master in the Heavenly Realm, he will have some self-protection power.

If it is simply competing with physical strength, he will not even be worthy of the other party.

Unless the ninth-level strongman who is fighting against is a master who specializes in body refining, he is confident that no one can defeat himself in physical confrontation.

"Well, it's time to say goodbye to Senior Lu Yu!" Lei Yi saw the impatient night sky bell on the side and immediately nodded to the other party.

In the villa.

Lu Yu has been waiting for a long time, but he is not without something to do.

In the yard, there is a small table with a feather arm, books, and a thick stack of paper.

"Senior Lu Yu, are you writing a book again?" Lei Yi came nearby and asked in a low voice.

After getting along for more than a month, he also knew that Lu Yu’s daily entertainment was actually just writing books.

However, many of the books he wrote are about space theory, and the content is obscure and difficult to understand. Even the princess of the Space Demon Clan, the Night Skyling, cannot understand it.

Of course, in addition to writing some books on space theory, Lu Yu also has some research, records, etc. on various races in the world.

In short, in addition to his strength, Lu Yu is actually a scholar with rich knowledge.

"If I were born in a peaceful era, I actually hope that you would call me 'Professor Lu' rather than Senior Lu Yu." This sentence has always been used by him to tease himself.

At this moment, Lu Yu was writing at his desk with a pair of black-framed glasses.

When he noticed Lei Yi appeared, he nodded without raising his head: "Boy, the training is over, are you going to go and have a chance?"

"Yes, I'm about to go out and explore, and the place where I'm going is the Demon Realm!" Lei Yi nodded.

As for why I went to the Demon Realm, it was because of my encounter outside the Tower of Time.

Since the Infinite Emperor sent himself to the Demon Realm, it means that there must be something that he needs to explore in the Demon Realm.

"Since that's the case, Lu won't stop you. I'll send you away from the Air Emperor Corps later!" Lu Yu nodded and stopped writing.

"Remember, among the seven emperors of the Demon Realm, they basically have a grudge against your father. If you have the power of time, try not to expose the secret of your power, otherwise most of the Demon Realm will not tolerate you!" He walked to Lei Yi and gave a careful advice.

Lei Yi's lips squirmed, but he still held back his complaints.

After all, he had never even seen his own father before, so he took such a big blame. The seven emperors of the Demon Realm were going to kill him and take revenge. Who can I ask for?

"You kid's bloodline is special. This book "Five Thunders Law" is also used for research. That boy Lu Yun has memorized this secret book so he doesn't need it anymore!"

"Go!"

Lu Yu threw a secret book to Lei Yi, then took out Kong Che, slashed out, and a space passage appeared in the center of the three.

"Senior Lu Yu, I'll say goodbye!" Lei Yi gave a fist-clamping ceremony and then walked into it.

"We can finally go out to wander, goodbye Professor Lu Yu!" Yekong was even more sensible and shouted affectionately. After waving goodbye, he took Pangpang to catch up with Lei Yi.

Lu Yu stared at the east of the Storm Demon Sea, where the endless sea area of ​​the Demon Realm was.

"Our plan is halfway through. Your son has only been here for three years, but he has grown even better than you and I expected."

"There is still something I didn't tell him, but I think someone will tell him the truth in the demon world..."
Chapter completed!
