Compared with demon beasts and demonic beasts, the human body is too weak and has almost no comparison, but people are very wise, before the endless era, human beings found that absorbing the aura of heaven and earth can make the human body stronger, and can even compete with powerful demon beasts.

However, the aura is extremely complex, not only is it not easy to absorb, but human beings continue to study and experiment, and eventually produce countless kinds of cultivation methods, which are collectively called exercises.

There are many different cultivation methods, some strong and some weak, not only the speed of absorbing and refining the spiritual energy is fast and slow, but the quality of the spiritual energy refined is also high and low.

According to the speed of absorbing and refining the spiritual energy, and the quality of the refined spiritual energy, the exercises are divided into four levels from low to high, the earth level, the heaven level, the Qiankun level, and the chaos level, and each level is subdivided into elementary, intermediate, advanced, and top.

There are a large number of exercises, but most of them are low-level exercises, especially the prefecture-level primary exercises, while the number of high-level exercises is extremely limited, especially the top-level exercises are extremely rare, and the limited number of high-level exercises is monopolized by big families and big forces, and ordinary people have no chance to obtain them at all.

For example, in Black Stone Town, the most advanced exercises are also the prefecture-level intermediate exercises, which are the reckless strength cultivated by Liu Yu and others.

Exercises can greatly increase a person's strength, speed, and physical strength, but only martial arts can make people exert their maximum combat effectiveness.

Martial arts can be divided into attack martial arts, defensive martial arts, body martial arts, and auxiliary martial arts according to different uses.

Like the exercises, martial arts are also divided into four levels and four orders according to the magnitude of their power.

Generally speaking, a technique will have a matching martial art, which can greatly exert its combat effectiveness.

The people of Blackstone Town are cultivating the ground-level intermediate martial arts Mangniu Jin, and when combined with the Mangniu Jin martial arts, they can use the power of other ground-level high-level martial arts.

Of course, a person's actual combat ability is also closely related to his mind and experience.

，，，

The blue sky was clear, the sun hung like a fireball, and the clouds seemed to have been burned and disappeared without a trace.

In the open space behind the town, a **** boy wearing gray shorts was slowly punching, one move at a time, the movements were very slow, but each punch had a fierce momentum.

Liu Yu slowly punched, and the aura in his body slowly accelerated like flowing water, flowing out of the dantian, and then returned to the dantian, completing the cycle after circle, and gradually Liu Yu's fist appeared with a white light.

"Drink!"

Liu Yu's momentum accumulated to the peak, and the whole person jumped up in the air, shot like lightning, like a tiger pounced, and punched the big iron pillar in the center of the clearing.

"Boom!"

There was a low sound of metal crashing, and the earth trembled slightly, and the energy dissipated, bringing up a fallen leaf on the ground.

A striking small fist mark appeared on the big iron pillar, about an inch deep.

"This is the power of the reckless cow Jin Xiaocheng, not bad!" The corners of Liu Yu's mouth twitched into a smile, and he muttered in a low voice: "But the spiritual energy is consumed too quickly, and it actually consumes almost one-tenth of my spiritual power at once." ”。

"Fifteen days, Mangniu Jin Xiaocheng!" Liu Yu smiled, Liu Yu found that he had a strong talent in cultivating martial arts, and this discovery made him very happy.

Reckless Niujin, it takes ordinary people half a year to cultivate to a small level, and the eldest brother also cultivated for a whole month, but it only took him fifteen days.

"There are still five months to go, Gruda Academy will start recruiting students, it is impossible to advance to the eighth layer of forging body, then work hard to cultivate martial arts, if the strength of the reckless cow can be great, my combat power should be raised to a higher level." Liu Yu thought secretly.

Unlike the exercises, which can only be practiced by obtaining the exercise map, the comprehension of martial arts is extremely difficult, and you must practice constantly before you can get started.

With the continuous practice of martial arts, the perception of martial arts will gradually deepen, so as to truly exert the powerful power of martial arts, according to the degree of mastery of martial arts, from weak to strong, it is divided into entry, small success, and large success.

And getting started and becoming a small success is the easiest, such as a prefecture-level intermediate martial art, as long as the brain is fine, you can practice it in half a year, but to advance to a large success, it takes a lot of time to practice, and it also requires a certain opportunity, to learn a prefecture-level intermediate martial art, three or five years can not be completed by a large number of people.

After the opening of the school year every year, Gruda Academy will hold an exchange meeting for new students, and the top 100 students in combat effectiveness will be focused on training.

Liu Yu's family knows his own family affairs, and the top 100 must be hopeless, but if he performs well and is selected by his mentor, it is still possible, although the eldest brother will definitely cover him, but everything can't rely on the eldest brother.

Sitting cross-legged by the iron pillar, he opened his eyes and stood up after a while.

The consumed aura has been fully restored, and the body has reached its optimal state.

Liu Yu held his breath and concentrated, slowly pushing one move at a time, although the action was slow, but there was an indescribable momentum, immersed in the boxing method to understand the artistic conception of the boxing, and constantly deduced and verified, after each round, the momentum in the punch was a little stronger, and it was a point.

After three hours and twenty rounds of fighting, there was a trace of condensation in the white light on the surface of the fist.

If Liu Ze and the others watched from the side, they would definitely be stunned, it would take them two or three days to make such progress, and Liu Yu only took half a day.

"Hehe, that's good. Liu Yu's mind moved, his spiritual power operated, and a thin layer of white light appeared on the surface of the fist, and then the white light flowed slowly, and finally condensed slightly.

"Go home for dinner!"

Liu Yu was very satisfied with this afternoon's training, grabbed the clothes hanging on the branches at the edge of the clearing, put them on his body and wanted to leave.

"Gaba!"

With a loud bang, the sky without a trace of clouds and mist slowly darkened, and a huge black vortex emerged, a huge vortex covered the entire sky, and a bucket-thick lightning swam in the whirlpool, and for a while, the wind on the ground howled, and the sand and stones flew wildly.

A ghostly light shot out of the vortex like lightning, and then the vortex began to dissipate.

In just an instant, everything in the sky disappeared without a trace.

The vortex appears quickly, but dissipates even faster, taking only a few breaths or so.

Looking at the blazing sun hanging high in the west, Liu Yu was a little in a trance, opened his mouth, and felt a little dry, was the scene just now real?

But seeing a large piece of scorched black land not far away, Liu Yu believed that the scene just now had really happened, and then the spirit shivered, if the lightning of the thickness of the bucket fell here, for a while Liu Yu only felt a chill down his spine, and turned around and was about to run in the direction of the town.

But as soon as he turned around, he tripped over a severed branch and fell forward to the ground.

In normal times, Liu Yu would never be knocked down by such a small branch, but at this time, Liu Yu's frightened legs were a little weak, although his heart was good, but after all, he was just a child.

Lying on the ground, Liu Yu rubbed his eyes vigorously, looking at a small gray stone ball not far away, and the moment he just fell to the ground, Liu Yu found that a white light flashed on the stone ball.

Liu Yu got up and walked over to pick up the stone, pinched it hard, knocked it again, and found that it was no different from an ordinary stone, but his intuition told him that this stone should be a treasure, Liu Yu grabbed the stone and looked around vigilantly, and found that there was no one, so he carefully put the stone on his chest, and then ran home.

"Could it be that there is a strange treasure from heaven and earth!"

"Maybe it's the wrath of the gods!"

、、、、、

Along the way, the people of the town were talking about the vision with horror on their faces, and the bucket-thick lightning frightened them.

Liu Yu ran back, and saw a familiar figure at the door of the house walking back and forth anxiously from a distance, seeing Liu Yu, Natu Susu ran quickly, first carefully took a large number of Liu Yu, and after seeing that there were no missing parts all over the body, he hugged Liu Yu fiercely in his arms, and said a little nervously: "Ah Yu, don't be scared, the lightning just now charged a small forest, I thought it was the end of the world."

Being held in his mother's arms, Liu Yu's heart flowed with heat, this is his mother, this is home, the first place he thinks of when he encounters danger and difficulties.

"No, my legs were scared weak just now, and I almost peed my pants. Liu Yu will always be a child who has not grown up in front of his mother, and at this time he grinned exaggeratedly and said a little shyly.

Hearing Liu Yu's answer, Natu Susu was immediately amused.
