Yuan Yi's fist exuded white heat, which was a phenomenon caused by a large amount of internal qi gathering under the fist, and the temperature on the fist at this time could even burn ordinary people.

It's such a terrifying punch, and at this time, I want to go away with this white-fronted tiger!

"Whew!!"

Feeling the threatening aura on the human body opposite, the big tiger howled, raised its front paws, and slapped towards Yuan Yi fiercely!

"Bang!!"

A wave of air erupted in the middle of the one-person-one-** battle, blowing the surrounding grass one after another.

Yuan Yi was smashed back three or four meters by the impact from his fist, while the white-fronted tiger on the opposite side was motionless.

Yuan Yi raised his hand and glanced at the scratches on his hand, and his heart sank.

"The power of this big insect seems to be too great......

Although he is only the third layer of the day after tomorrow now, the first-level Xuantian Gong makes his foundation, strength, and total amount of internal qi not inferior to the fourth layer of the day after tomorrow, and his true combat power should be at the peak of the fourth layer of the day after tomorrow.

Coupled with Yuan Yi's previous cultivation all the way to the innate combat experience and transportation method, he could even go to fight with the fifth layer of the day after tomorrow.

But as soon as he fought this white-fronted tiger, he fell into such a disadvantage, which he had never encountered before.

"This is an acquired fifth-layer fierce beast!"

Yuan Yi immediately made a judgment, only the fifth layer of the day after tomorrow can have this power!

After realizing that this eye-catching white-fronted tiger was an acquired fifth-layer fierce beast, Yuan Yi hesitated in his heart.

He is only the third layer of the day after tomorrow, and he is not the opponent of this white-fronted tiger for the time being, so there is no need to fight to the death with it.

Moreover, in the past three days, he has killed countless fierce beasts from the first layer to the fourth layer of the day after tomorrow, and now he is only a little experience point away from being able to level up.

As long as Yuan Yi is upgraded to the fourth layer of the day after tomorrow and steps into the middle stage of the acquired realm, his strength will usher in a skyrocket!

Coupled with the eighteen palms of the dragon descending, Yuan Yi, who is on the fourth layer of the day after tomorrow, will definitely be able to easily kill this white-fronted tiger.

"In that case, then retreat, and when I level up, I'll kill this big bug again. ”

Yuan Yi thought of this, and his body slowly retreated.

He has always been a rational person, and he will not lose his life without thinking, this is true in his previous life, and it is also true in this life.

"Whew!!"

Seeing that Yuan Yi had the intention of leaving, the white-fronted tiger immediately howled, his body rushed forward, and the tiger's mouth was wide open, about to bite Yuan Yi's brain!

The white-fronted tiger is the strongest beast in this area, how can it tolerate Yuan Yi's attitude, it wants to bite off Yuan Yi's head and trample Yuan Yi's corpse to the ground, in order to set an example!

When Yuan Yi saw the white-fronted tiger biting at him, and didn't want him to leave at all, his calm face suddenly became hideous.

"Since you don't want me to go, then send you to die!"

He was a rational person, a very rational person.

But when others don't let him be rational, Yuan Yi will no longer be rational, and he will no longer be a person at that time.

Yuan Yi raised his left fist, injected internal qi into it, and struck at the white-fronted tiger with hanging eyes.

The white-fronted tiger's mouth bit on Yuan Yi's left fist fiercely, and the fangs and huge force instantly broke through his skin, and blood flowed out desperately.

The tremendous strength of the white-fronted tiger and the stinging pain of the fangs piercing the skin made Yuan Yi's left arm immediately lose sensation.

At the same time, the power on Yuan Yi's left fist also smashed firmly into the roof of the white-fronted tiger's mouth, making it suddenly stunned.

A tingling pain came from Yuan Yi's left arm, and the feeling seemed to tear his arm apart, making his face even more hideous.

"Die!" Yuan Yi raised his right fist and slammed it on the head of the white-fronted tiger.

"Bang!" the fist slammed firmly into the white-fronted tiger's head, causing it to let out a 'purr' cry in its throat.

Yuan Yi raised his fist again and smashed it into the head!

"Die!"

"Bang!"

Yuan Yi's fist smashed against the skull of the white-fronted tiger with a muffled sound.

"Whew!!"

The white-fronted tiger released its big mouth in pain, and then suddenly closed violently, and the huge bite force hit Yuan Yi's arm fiercely!

"Click!" A crisp sound came out, and Yuan Yi's right arm was broken.

"Humph!!"

Under the impact of the sharp stabbing pain and the sharp pain of the broken arm, Yuan Yi couldn't help but let out a muffled snort.

Cold sweat oozed from his forehead, and his left arm was completely devoid except for the sharp pain.

But Yuan Yi didn't stop, and smashed another punch on the head of the white-fronted tiger!

"Die!"

"Bang!"

"Whew!!"

The white-fronted tiger with hanging eyes was in pain, and his expression gradually became crazy, and he bit Yuan Yi's left arm frantically, wanting to completely tear his left arm off!

Yuan Yi's face was extremely hideous, and he smashed one punch after another on its head!

"Die!"

"Bang!"

"Whew!"

"Die!"

"Bang!"

"Whew!"

"Die!"

"Bang Bang Bang !!"

Yuan Yi frantically smashed the head of the white-fronted tiger, punch after punch, and the white-fronted tiger was also frantically biting his left arm.

"Click!"

After dozens of punches, a crisp sound suddenly came from the skull of the white-fronted tiger, and its skull shattered......

At this time, its face was already full of blood, and Yuan Yi punched it down dozens of times, smashing it into a bloody head, and at this moment, the skull was shattered, and the eyes of the white-fronted tiger suddenly lost color.

It couldn't even understand why it was so desperately biting the arm of the human in front of it, but it kept gnawing. Instead, it died first.

Of course, it didn't know that Yuan Yi was an Innate Realm martial artist before, although he had lost his strength, his bones were very hard, it was just an acquired fifth-layer fierce beast, how could he be able to gnaw it.

"Ding! Congratulations to the host for killing the fifth-layer white-fronted spirit tiger beast the day after tomorrow and gaining 10 experience points!"

"Ding! Congratulations on the upgrade of the host! The current level is the fourth layer of the day after tomorrow!"

At the same time as the white-fronted tiger died, two system prompts also sounded in Yuan Yi's mind!

At the moment when the system prompt fell, the surrounding heaven and earth aura suddenly fluctuated violently, and Yuan Yi's body turned into a large whirlpool, and began to absorb a large amount of the surrounding heaven and earth aura.

The aura entering the body made Yuan Yi feel as if he was immersed in a warm ocean, and at the same time, these aura was also quickly integrated into Yuan Yi's body, quickly strengthening his physical fitness.

At this time, Yuan Yi could clearly feel that he was rapidly becoming stronger, and every cell in his body was extremely active and slowly growing.

His physical fitness increased extremely quickly in such an environment, and the speed visible to the naked eye simply made Yuan Yi a little frightened.

According to the picture in his memory, the improvement from the third layer of the day after tomorrow to the fourth layer of the day after tomorrow is very large, but it is not so exaggerated.

The acquired realm is a realm specially used to improve physical fitness, and the difference in the strength of each realm of martial artists in this realm is particularly obvious.

Because the martial artists of this realm have not learned too many martial arts, let alone be proficient in a martial art, the pure physical fitness is the most direct and critical factor.

In the martial arts system, each major realm is divided into nine small realms, such as the first to nine layers of the day after tomorrow, and among these nine small realms, they are divided into three steps.

That is the early, middle and late stage of each realm, and the difference in the strength of the martial artists in these three stages is huge.

There may be some geniuses who can fight the third layer of the day after tomorrow or even win in the second layer of the day after tomorrow, but if it is the third layer of the day after tomorrow and the fourth layer of the day after tomorrow, the difficulty will be greatly increased to a nightmare-level difficulty.

This is because in the ancient flood period, the number of Terran warriors was extremely small, most of them were ordinary people, and cultivation was not popular.

At that time, the Terran warriors were crossing the river by feeling the stones, and without the guidance of their predecessors, they could cultivate blindly on their own.

Later, cultivation gradually became popular, and slowly some people divided the realm according to the law of the strength growth of martial artists.

And there are nine small realms in each realm, and three of them are a strength stage, so the gap in strength between the early, middle and late stages of the human warriors will be huge.

But if Yuan Yi is not mistaken, before he was abolished, he was promoted from the third layer of the day after tomorrow to the fourth layer of the day after tomorrow, and his strength has probably increased by about eighty percent, which is extremely exaggerated.

But he has only been breaking through for a long time now, and his physical fitness has already exceeded eighty percent! And it is still rising!

Yuan Yi was stunned as he watched as the surrounding aura continued to pour into his physical strength, and these aura was about to materialize, flowing into his body like white ribbons.

In the blink of an eye, Yuan Yi's physical fitness has increased to ninety percent!

And after a while, that number rose directly to ten percent!

Now, Yuan Yi's physical fitness has doubled before, if he encounters an identical white-fronted tiger again, relying on his physical fitness alone, Yuan Yi can easily kill it!

Before, Yuan Yi thought that he could easily kill the white-fronted tiger by upgrading to the fourth layer of the day after tomorrow, but that was because he had counted the eighteen palms of the dragon descending, but now, he suddenly had this confidence!

"No! I haven't stopped yet! I'm still getting better!"

Yuan Yi was already happy, but he was shocked to find that the aura around him had not stopped, and it was still inhaling into his body continuously!

At the same time, his physical fitness is also rapidly increasing at a speed that is visible to the naked eye!

Eleven percent!

Twelve!

Thirteen percent!

Fourteen percent!

Fifteen percent!

Yuan Yi was dumbfounded and felt the rapidly increasing power in his body, and at this moment he was completely confused, his mouth opened into an O-shape, and his head was full of mush.

"What's going on, how can the force of this breakthrough be the same as that of Kaihang......"

But the aura was still pouring into his body, making his mouth open wider and wider, and finally his eyes were full of ecstasy and shock.

Sixteen percent!

Seventeen percent!

Eighteen percent!

Nineteen percent!

Twenty percent!

Twenty-one percent!

In the end, Yuan Yi's physical fitness slowly stopped at the twenty-first percent, and his physical fitness was directly increased by two and a half times compared to him when he was in the third layer of the congenital layer!
