At first, Yang Xiaole was not familiar with the route of blood circulation, so he only sensed the blood in his body with his mental power and quietly observed its flow.

As time passed, Yang Xiaole's spirit gradually and completely focused on the blood circulation, and his perception of the outside world became blurred, but his perception of his own body became clear.

Gradually, a three-dimensional picture of the internal landscape appeared in Yang Xiaole's mind, in which various tissues and organs, blood vessels, nerves, bones, and even tiny cells were presented one by one.

At this time, Yang Xiaole began to try to guide the blood in his body, accelerate the flow along the blood vessels, perfuse to the limbs, and nourish the tissues and organs of the body.

Yang Xiaole guided the blood to complete a large circulation in the body before he stopped cultivating, only to feel refreshed and full of inexhaustible energy.

Then, he attempted to slice his own arm with his claws, sending out a bloody blade.

This time, the blood blade was much stronger, and it made a muffled sound of "bang" on the wall of the private space, but it still failed to destroy the wall, and the lethality was still limited.

Yang Xiaole shook his head and muttered to himself: "It seems that this Blood Sea Demon Skill can't be achieved overnight, and it needs to be practiced a lot!" ”

At this time, the time was also seven o'clock in the morning, Yang Xiaole thought about it and teleported to the public space.

It was the first time for Yang Xiaole to come to the public space, and he found that it was similar to the team space and private space, with only four white walls, white ceilings and floors, but the area was much larger than the team space, the size of several football fields.

But at this time, there are only a few dozen people in the public space, and most of them are dozing off while setting up stalls, and a few stalls have energy coins written on them, but the stall owners don't know where to go.

"It looks like I'm coming early, so I'd better wait until later!" Yang Xiaole shook his head, teleported out of the public space, and returned to his room.

After eating the soy milk fritters bought by his mother, Yang Xiaole came to the park on time, practicing boxing while waiting for Jiang Yue's arrival.

But after waiting for a while, I only waited for Jiang Zhongyan to come.

"Teacher, why are you the only one here today?" Yang Xiaole asked puzzled.

Jiang Zhongyan smiled and said, "Your senior sister's martial arts realm is also about to break through, I asked her to go to a certain place to retreat and practice, by the way, how is your Xingyi Five Elements Fist practice?" ”

Yang Xiaole hurriedly said: "I feel like I'm about to reach the peak of Ming Jin!" ”

Jiang Zhongyan said: "Okay, I'll practice with you today!" ”

As he spoke, Jiang Zhongyan hit Yang Xiaole with a cannon fist.

Yang Xiaole also hurriedly used the Xingyi Five Elements Fist and practiced against Jiang Zhongyan.

Under the personal guidance of Jiang Zhongyan, Yang Xiaole's progress has advanced by leaps and bounds, and after more than a dozen times of sparring, he suddenly broke through to the peak of Ming Jin.

"Very good, you finally broke through!" Jiang Zhongyan laughed, and suddenly slapped Yang Xiaole's fist lightly, causing Yang Xiaole to take several steps backwards as if he had been electrocuted, before he could barely stand firm.

"Teacher, what kind of kung fu did you just do that made me feel like an electric shock?" Yang Xiaole asked unsurprised.

Jiang Zhongyan stroked the beard under his chin and said: "This is the so-called dark energy, also known as inch strength, which is the whole energy that bursts out in a very short time and distance, and after practicing the dark energy, there will be a strong bioelectricity, which can drive the muscles to burst out in a short period of time, so you will feel electrocuted, but the main lethality still depends on the explosive power of the muscles!" ”

Yang Xiaole said excitedly: "Please ask the teacher to teach me the secret kung fu!" ”

Jiang Zhongyan nodded and said: "No problem, then I will teach you the twelve forms of Xingyi Fist, these twelve forms are the key to cultivating dark energy, the principle is to use the inertia generated by body movement, as well as the body stress adjustment at the moment of contact with the enemy, to beat the weight out, the bright energy and the dark energy are actually the whole energy, but one is obvious, and the other is secret!" ”

As he spoke, Jiang Zhongyan began to practice one by one, and stopped to explain from time to time.

Soon, Jiang Zhongyan practiced all the twelve forms of Xingyi Fist, such as dragon, tiger, monkey, horse, dragon, chicken, swallow, harrier, snake, shearwater, eagle, and bear.

With his powerful perception and intelligence attributes, Yang Xiaole forcibly memorized the movements and essentials of the twelve shapes, and learned to practice them again.

Jiang Zhongyan nodded with satisfaction and said: "Very good, you are really a genius, this Xingyi Fist Twelve Shapes is the most particular about dark energy, and it is also the easiest to hurt people, so it is not suitable for sparring with others, unless the other party is a master of turning strength, I am old, and I don't have the energy to accompany you to practice, so you can only practice by yourself!" ”

Yang Xiaole nodded and said, "Okay, then I'll practice by myself!" ”

Jiang Zhongyan took out a business card, threw it to Yang Xiaole and said, "There is my phone number on it, when you have practiced dark energy, come to me to learn the exercises of transforming strength!" ”

As he spoke, Jiang Zhongyan turned around and floated away.

Yang Xiaole hurriedly took the business card and said respectfully: "Thank you, teacher, go slowly!" ”

Then, Yang Xiaole practiced the twelve forms of Xingyi Quan a few more times, completely integrated his moves into his body's instinctive memory, and returned to his home.

Then, Yang Xiaole teleported to the public space.

This time, there are more people in the public space, there are thousands of people, from time to time there are stall owners shouting and selling, and many people walking around asking for prices.

Yang Xiaole walked around the public space, secretly learned the prices of various goods, and then returned to his private space to take out the batch of gold, silver and jewelry, and came to a stall owner who specializes in buying and selling energy coins.

The stall owner is a big man with tangled muscles, and his face is hidden by the system, and he can't see clearly, and everyone who enters the public space is like this, which should be to prevent being recognized and causing vendettas.

Yang Xiaole threw the blanket bag full of gold and silver on the ground, opened the box full of jewelry, and said to the stall owner: "I have a batch of gold and silver jewelry here, can you accept it?" ”

The big man's eyes lit up and he said, "Accept it, of course you accept it, but the gold, silver and jewelry are not easy to get rid of, and it is relatively priceless to exchange them for energy coins!" ”

Yang Xiaole smiled and said, "I'm a long-term deal, if the price you give is good, I will sell all the gold, silver and jewelry to you in the future!" ”

Hearing this, Dahan's eyes narrowed, and he said, "Could it be that you have discovered a certain world where you can plunder a large amount of gold, silver, and jewelry?" ”

Yang Xiaole shrugged his shoulders and said, "Almost, how about it, what price do you give me?" ”

Dahan gritted his teeth and said, "Okay, I won't suppress your price, I will convert the goods according to the market price of the earth, and then pay your energy coins at the exchange rate of 10,000 US dollars for one energy coin, how about it?" ”

Yang Xiaole grinned and said, "Deal!" ”
