The attack power of the Black Dragon Law Aspect is indeed very strong, and it is far beyond the estimate in Long Fei's heart, which is inevitably related to the fact that the power obtained by Yin Gengyu is too strong and too perverted.

When he was slapped by the power of the black dragon's claw, Long Fei clearly saw his blood volume, almost bottoming out.

Even if the power of the Black Dragon Law Phase is a little stronger, then he will really hang up.

Fortunately, his recovery ability was really perverted, and by the time the impact force caused damage to his flesh and blood for the second time, most of his HP had already recovered, and it was not a problem to withstand the second aftermath attack.

In just over ten seconds, Long Fei actually heard the system voice prompt that made him feel excited and surprised, that is, the information of the "Earth Vein Treasure Body" exercise to improve the level.

"This time the level of promotion, that is equivalent to my life in exchange for the gamble, in the future with others, never make such a mistake again, even if it is after the system level is upgraded, it will give me a subsequent system level promotion, increase the difficulty, but also to ensure the safety of my own life first. ”

Hearing the sound prompt of the system, Long Fei took a deep breath, raised his hand to wipe the blood from the corner of his mouth, and then stood there, looking coldly at the approaching black dragon law, and an indifferent smile appeared on his face.

Originally, Yin Gengyu thought that Long Fei would die.

But the facts told him that Long Fei was intact, as if he had never been attacked, which made Yin Gengyu really unacceptable, and his mind almost collapsed at this moment, and he exclaimed in his heart: "What's going on? Why isn't this guy dead? Could it be that he has cultivated an immortal body? As far as I can remember, only a master who has cultivated to reach the pinnacle of the realm of life and death can practice an immortal body." If he really cultivated the immortal body, then this also means that his strength has reached the 8th and 9th levels of the realm of life and death. No, it can't be. If he was really that strong, he wouldn't have been beaten by me and vomited blood. ”

"Are you very disappointed to see that I'm fine?" Long Fei said with a smile.

"Damn, how did you manage not to kill?" Yin Gengyu said angrily.

"I can kill, it's just that your strength is not enough, so I didn't die. Long Fei was very frank and told the truth.

It's just that these words, to Yin Gengyu's ears, seem to insult him and make fun of him again.

Hearing Long Fei's words, Yin Gengyu was almost so angry that he vomited blood.

Withstood Yin Gengyu's strongest attack power, and the "Leyline Treasure Body" technique was also successfully improved by one level, which made Long Fei's self-confidence greatly improved, knowing that no matter how he fought Yin Gengyu next, Yin Gangyu would not be able to kill him.

So, when the Black Dragon Law Minister, controlled by Yin Gengyu, stopped there, Long Fei jumped up, and then swooped down, unexpectedly launching a provocative attack formation towards the Black Dragon Law Minister.

In the face of Long Fei's provocation, Yin Gengyu couldn't bear to look at it directly, and directly burst out, controlling the black dragon law phase, and performing combo moves, launching a new round of strong offensive against Long Fei.

Long Fei's attack power, compared to the black dragon law at this moment, is extremely weak, and it is impossible to compete with it at all.

Long Fei provoked Yin Gengyu, naturally in order to achieve the purpose of forcing Yin Gengyu to make a quick and strong move, so as to consume his strength.

If Yin Gengyu knew Long Fei's true intentions, then he wouldn't be so angry and uncalm.

"Bang ......"

Long Fei's body, like a sandbag, was hit by the continuous critical attacks of the black dragon law phase, and there was a huge impact sound that made people feel frightened when they listened to it.

Although he was being beaten, Long Fei was secretly happy in his heart.

Because of the sound of the system's voice announcing the good news, it sounded rhythmically one after another, telling him that the experience value of the "Earth Leyline Treasure Body" exercise was accumulating at an extremely fast speed, approaching the base of the promotion level.

The attack frequency of the Black Dragon Law Phase is almost to the extreme.

In less than a minute, he launched one thousand and thirty-nine attacks on Long Fei, thus making Long Fei once again use his powerful attack power to raise the "Leyline Treasure Body" technique by one level, reaching the current level of 8.

That is to say, Long Fei's current defense is strong enough to easily withstand the heavy blows of the 7th level masters of the ordinary realm of life and death without dying.

Manipulating the black dragon to perform combo moves is a great consumption for Yin Gengyu.

After this attack, Yin Gengyu activated the sacrificial array, and half of the power he had obtained from an evil god in the void had been consumed, which greatly weakened his combat power, defense, and reaction speed.

And the current state of the Black Dragon Law Xiang is under Long Fei's absolute control, when he stopped and suspended the violence, Long Fei immediately performed the "Dragon Fist" technique to launch a counterattack offensive against the Black Dragon Law Minister.

The 83-level "Dragon Fist" technique has amazing lethality, and it is not a problem to kill the masters of the 2nd and 3rd levels of the realm of life and death in seconds.

At this moment, when Long Fei launched a counterattack, he also cast a spell to stimulate the power enhancement effect of the "Blood Tyrant Divine Skill", which greatly improved the power of the "Dragon Fist" technique.

Therefore, every time Long Fei was hit hard with a punch, there would be traces of collapsed fist marks on the body of the black dragon law minister.

Three thousand and twenty-four punches were punched out in a row.

The black dragon law phase was completely deformed by Long Fei, and the skeleton was exposed in many places, and the whole looked like an old dragon that was already in the last years of the wind and candle, and it could fall to the ground at any time, and he would die with a whimper.

"Damn bastard, I'm fighting with you, even if I die, I'm going to pull you back. Knowing that there was no way out, Yin Gengyu roared angrily, and then without hesitation, he urged the only remaining power in his body and cast a self-detonation secret technique.

"Bang!"

The Black Dragon Law was connected to Yin Chengyu himself, and they all exploded directly, making an earth-shattering sound, a powerful and terrifying power, instantly centered on the body of the Black Dragon Law Phase, like a stormy wave, rushing towards the surrounding space.

In just one second, the entire underground space is filled.

The hard rock wall in the distance was violently impacted, like paper paste, and quickly collapsed, turning into gravel and dust chips, and flowing down the river in the direction of the impact of the force.

Long Fei was too close to the Black Dragon Law and sensed that Yin Gengyu was about to blow himself up, but he didn't have time to react, so he had to exchange all the remaining more than 2 trillion spirit points for the experience points needed to improve the system at the first time, and raise his system level to the highest, so as to increase his blood volume, in case he was attacked, the blood volume was insufficient and an accident occurred.

Since Long Fei's current level is level 80, the base for upgrading the system level is 80 billion, and Long Fei will have to spend 800 billion spirit points if he exchanges spirit points for experience points, calculated at ten to one.

The base for moving up to the next level is 90 billion points.

Therefore, Long Fei's remaining more than 2 trillion spirit points are only enough for Long Fei to upgrade two system levels to level 82 in such a crisis situation, and his blood volume has increased from 108 billion points to the current 135 billion points.
