Huang Yongle was about to mutate for the fourth time, which meant that he had to retreat and cultivate again, and he needed to be accompanied by Ye Zi.

Huang Yongle is now in the Ice Country, and he has two choices: either he returns to Huaxia Country to find Ye Zi, or let Ye Zi come to the Ice Country to find him.

The situation in the Ice Country is currently unstable, and it is somewhat dangerous for Ye Zi to come to the Ice Country. Although the danger is not great, it is impossible for Huang Yongle to let his girlfriend take such a risk.

Therefore, Huang Yongle decided to return to Huaxia by himself.

Before returning to China, Huang Yongle used the matching function of the system to promote more than a dozen talents in the Ice Country, and let them hold important positions in the Ice Country, responsible for maintaining order in the Ice Country and avoiding chaos.

The reason why Huang Yongle wants to maintain the order of the Ice Country is not only for the Ice Country, but also for the sake of all countries in the world.

Because once the order of the Ice Kingdom collapses, it will become a paradise for criminals, and at that time, the Ice Kingdom will give birth to many criminal-criminal mutants. Once the number of criminals and mutants increases, it will be a great disaster for the whole world.

Therefore, Huang Yongle promoted the right talents to maintain the law and order of the Ice Country and prevent it from becoming a country of criminals.

After dealing with these things.

On September 16, Huang Yongle took a flight from Yake City to Fuxing City in China.

Huang Yongle has been abroad for more than a month, and this time he returned home and saw his family again, and he was in a good mood.

Ye Zi was also very happy.

She hasn't seen her boyfriend for more than a month, which is the longest time the two have been apart since they fell in love. Ye Zi was overjoyed to see her boyfriend go home, and her happiness index soared by more than 1,600 points to 41,564 points.

One of the most important reasons why Ye Zi's happiness index is so high is that she has learned martial arts.

In the past two months, Ye Zi has not only learned the light gong "Flying on the Grass", but also learned "Taijiquan", her understanding is extremely high, and both martial arts are close to completion.

Knowing that Huang Yongle was about to mutate for the fourth time, Ye Zi went to the Banana Villa with him to retreat and prepare for the mutation.

……

At night.

Banana villa, bedroom.

Huang Yongle was lying on the bed, Ye Zi was lying in his arms, his bodies were tightly together, like glue. The two have been separated for more than a month, and now they are finally together, and they are naturally intimate.

"Baby, you've worked hard all this time. ”

"No, I'm quite idle, but you have to deal with so many mutant dogs in the Ice Country, that's called hard. Ah Le, hasn't that 'Mutant Demon King' been caught yet?"

"Not yet. The Mutant Demon King is a master-level criminal, and it is not so easy to catch him. However, I have allied myself with him as Sheriff Raymond, and if I gain his trust, I will be able to find clues. ”

"There won't be danger, right?" Ye Ziliu frowned slightly, and admonished, "Ah Le, although it is very important to catch the criminal, you must also pay attention to safety, and don't take too many risks." ”

Huang Yongle smiled and kissed Ye Zi's cheek: "Baby, don't worry, everything is in my hands, and there will be no danger." ”

Ye Zi nodded lightly, like a kitten, affectionately snuggled up to Huang Yongle's chest.

……

Two days after that.

Ye Zi has always been by Huang Yongle's side, and Huang Yongle's happiness index has been successfully maintained at 79999.

Since it is the fourth mutation, it needs to be maintained for a longer time than the previous three times.

After maintaining it for about 40 hours, in the early morning of September 18, the happiness index finally exceeded 80,000 points and successfully mutated.

After the mutation, Huang Yongle fell asleep and lay in the bedroom.

Ye Zi went to the kitchen and began to prepare food for her boyfriend. When she returned to her bedroom, she noticed something strange.

When Ye Zi walked to a position about four meters away from Huang Yongle's body, an invisible barrier suddenly blocked her in front of her.

This invisible barrier was as solid as gold, no matter how hard Ye Zi tried, he couldn't get close to Huang Yongle for half a minute, and he was always blocked four meters away.

"Dizzy, what's going on?"

Ye Zi looked puzzled.

Why can't I get close to my boyfriend? What is this invisible barrier?

In fact, this invisible barrier is the vajra qi wall around Huang Yongle's body.

When Huang Yongle was conscious, he could put away the vajra qi wall around him so that others could get close to him. However, after Huang Yongle fell asleep, the vajra qi wall would automatically wrap around his body, forming a defensive layer, so Ye Zi could not get close.

Huang Yongle's Vajra Qi Wall was originally only 2 meters thick, but after the fourth mutation, the Qi Wall suddenly increased to 4 meters thick.

This is because Huang Yongle's body has been upgraded, and his internal cultivation has also been upgraded.

The total amount of internal force that can be stored is different for different bodies.

People who have cultivated the "Jiuyang Divine Skill" will continuously generate Jiuyang True Qi in their bodies. It's just that the true qi that ordinary people's bodies can store is limited, so the internal strength of ordinary people is also limited.

And when a person mutates, the body is upgraded, and the total amount of true qi that can be stored increases, and the internal strength is also improved.

It was precisely because of this that after Huang Yongle's fourth mutation, the true qi in his body increased rapidly, and his internal cultivation directly doubled, and the thickness of the qi wall around his body reached an astonishing four meters.

Such a thick wall of vajra gas can almost withstand the bombardment of artillery shells.

"How so?"

Ye Zi was a little speechless, her boyfriend was lying in the bedroom, but she was isolated by the air wall four meters away, out of reach, this is simply the farthest distance in the world.

Unable to get close to Huang Yongle, Ye Zi could only stay at the door of the bedroom and guard from afar.

This is more than 20 hours.

In the early morning of September 19, Huang Yongle finally woke up. After the previous three mutations, they were all very hungry, and he thought that after the fourth mutation, he would be even hungrier.

However, the situation turned out to be unexpected.

After Huang Yongle woke up, not only did he not feel hungry, but he was full of physical strength and energy.

What's going on?

I haven't eaten for a day and a night, so why don't I feel hungry?

It turned out that after the fourth mutation, Huang Yongle's body cells had a qualitative change, and the cells were already able to directly store true qi and did not need food to provide energy.

As a result, the true qi generated in Huang Yongle's body was continuously poured into the cells of the body, and all the cells were in a state of full energy.

Even if you don't eat, you won't feel hungry.

In other words, after the fourth mutation, Huang Yongle can already use True Qi as "food" to obtain energy from True Qi to maintain the body's metabolism.

He can skip eating, but directly absorb the true qi in his body as the body's energy.

Huang Yongle's body is full of true qi, and with his internal cultivation, it is no problem not to eat for half a month.

Of course, he can also eat if he wants.

In addition to metabolism, Huang Yongle's body also has many wonderful changes.

For example, his heart rate is even slower, only about 5 beats per minute, with an average of 12 seconds.

Also, his breathing rate is slower, only about 2 breaths per minute.

In fact, Huang Yongle can't even breathe.

Even if Huang Yongle holds his breath for 1 hour, his body can function normally. Because he can not absorb oxygen from the air, but directly use the true qi in the body to maintain the body's metabolism.

All this is because the body has undergone qualitative changes after the fourth mutation, and the metabolic mode has been fully upgraded.

You can skip eating, you can not breathe, and you can survive with only your true qi.

However, if the mutant does not have true qi in his body, he still has to eat and breathe.

Huang Yongle is able to transcend food and air because he has cultivated his true qi and can use his true qi to provide energy to his body.

All kinds of wonderful changes in his body have opened Huang Yongle's eyes. However, what pleases him the most is the upgrade of his brain power.

In the past month or so, Huang Yongle has gradually formed a new set of martial arts theories in his mind. It's just that this set of martial arts theories still has many flaws, and it is a bit scattered and unsystematic.

Now after the fourth mutation, Huang Yongle's brain power has been comprehensively improved, as if he has been enlightened, and many martial arts problems that he had not been able to understand before suddenly opened up. The original fragmentary martial arts inspiration miraculously fused together and related to each other.

For a while, Huang Yongle couldn't help but have a large number of new martial arts ideas in his mind, and all the martial arts he had learned before were like small streams, which were gathering together at a rapid speed, merging with each other, and returning to their ancestors, jointly deducing a new set of martial arts frameworks.

Huang Yongle faintly felt that the time for his own martial arts seemed to be ripe.

The new martial arts he had conceived for a long time was already close at hand!

What he needs to do now is to find a quiet place and sort out the martial arts ideas in his brain.

Thereupon.

Huang Yongle went to the underground warehouse of Banana Villa and began to devote himself to studying martial arts.

Since the amount of martial arts information in my mind is so huge and vast, it takes a lot of time to study.

The martial arts that Huang Yongle wants to create himself is a set of martial arts related to mutation.

Variation comes from happiness, so Huang Yongle's self-created martial arts are based on happiness.

The mystery of happiness is the essence of this set of martial arts.

The connotation of happiness is all-encompassing, broad and profound, and to understand it thoroughly, it requires extraordinary understanding.

Huang Yongle's happiness index has exceeded 80,000, and his understanding and perception of happiness are beyond the reach of ordinary people, which is the foundation for his self-created happiness martial arts.

After studying for three days and three nights, Huang Yongle finally sorted out this set of happy martial arts, and the whole set of martial arts has gradually taken shape.

Unfortunately, there are still several unsolved problems.

As long as these recent problems are solved, this set of happiness martial arts will be completed.

However, Huang Yongle racked his brains and still failed to break through the last bottleneck. Although he has learned so many martial arts, there are still some blind spots in martial arts.

"It seems that my martial arts background is still not enough!"

Huang Yongle sighed secretly.

To break through the final bottleneck, it seems that it is necessary to get in touch with more martial arts and clear the blind spots of martial arts.

However, the top-level martial arts of the time and space of "Smiling Proud Jianghu" have been drawn, and there is no point in continuing to draw......

"Huh?"

At this time, Huang Yongle found that the system's space-time icon was changing.

The timeline of time and space is changing rapidly, and it is going backwards!

Yes, time is turning back.

Before, the timeline of time and space has been advancing, but at this moment, it is regressing, from the time and space of "Smiling Proud Jianghu", constantly regressing to the previous time and space.

The process of regression goes like this:

[Smiling Proud Jianghu] - July 15, 1486!

↓

[Heaven and Dragon Slayer] - June 6, 1351!

↓

【Condor Heroes】-January 13, 1244!

↓

[Legend of the Condor Heroes] - February 3, 1172!

↓

【Tenryu Hachibu】-January 1, 1060

……

The timeline suddenly retreated by more than 400 years, from "Smiling Proud Jianghu" to "The Legend of the Condor Heroes", and finally stopped in the time and space of "Dragon Babu".

Seeing this result, Huang Yongle couldn't help but smile.

He is now encountering a bottleneck and needs to study some more martial arts, and as a result, the system immediately opened the time and space of "Dragon Babu", which is simply a relief in the snow.

In terms of martial arts cheats, the time and space of "Dragon Babu" is undoubtedly the richest, and there are many peculiar martial arts, which are very valuable for reference.

Now that he has entered the time and space of "Dragon Babu", Huang Yongle decided to draw the martial arts cheats immediately.

In order to save happiness index, it is better to choose a random lottery.

I drew 43 times, but I didn't get the martial arts cheats. It wasn't until the 44th time later that there was finally a turnaround.

"Ding! Congratulations to the host, you have drawn the Flame Knife of Gu Mozhi!"
