With the Tianjing assisted in cultivation, Long Fei, who was in a state of cultivation, could clearly see the experience points of the "Heavenly Vein Treasure Body" exercise upgrade through the personal attribute panel, which was beating at an extremely fast speed.

However, every time the data jumps, a large number of Celestial Crystals are consumed.

It's just that Long Fei didn't bother to pay attention to the consumption of Tianjing, because in his opinion, the "Heavenly Vein Treasure Body" exercise can be upgraded, that is the most important thing, as for Tianjing, for him, in addition to being able to assist in the cultivation of the "Heavenly Vein Treasure Body" exercise, he really can't find any other use.

Minutes and seconds passed.

In the blink of an eye, three months had passed, and Long Fei had completely consumed all the Heavenly Crystals obtained from the Luo family, thus directly raising the Heavenly Vein Treasure Body technique from the original 14-level level to the current 18-level level.

This means that even if Long Fei encounters the strongest means of attack by a master at the top level of the Chaos Realm, he can use the super defense of the "Heavenly Vein Treasure Body" technique to carry it down and not be killed.

With such a strong defense as a guarantee, breaking into the Sevenfold Heavenly Demon Domain, for Long Fei, life is equivalent to a guarantee, even if his identity is exposed in the Demon Domain and he is besieged by a large number of powerful demons, he can have the power to protect himself.

After running out of heavenly crystals, Long Fei stopped practicing, and then no longer hesitated, and in the depths of this underground space, he directly cast a secret technique to open the passage connecting the Seven Heavenly Demon Domains controlled by Xi'en.

There is no problem with the tantric method taught by Luo Tianmeng.

With the use of the secret technique, the passage connecting the Seven Heavenly Demon Domains controlled by Sheen was successfully opened, and Long Fei did not hesitate at all, and immediately stepped into the passage portal that appeared in front of him and entered the passage.

The teleportation channel, while not so stable, is not much of a danger.

After a journey of about ten minutes, Long Fei successfully reached the Seven Heavenly Demon Domain controlled by Xi'an.

Appearing in this piece of heaven and earth, Long Fei suddenly felt a magical aura that disgusted him, surging towards him like a torrent, as if he wanted to plunder the vitality in his body and turn it into magical power.

"The environment in which the demons live is really not suitable for humans and other creatures to live for a long time, and it is necessary to purify all the magic power between this heaven and earth so that humans and other creatures can live normally. ”

Long Fei frowned slightly, and then directly used the "Reverse Blood Transformation Demon Skill" to disguise himself as a wolf-faced demon head, and instead breathe with a demon's lifestyle, the uncomfortable feeling in his body was improved.

Whoosh ......

As soon as he turned into a demon, more than a hundred figures flew towards his location from all directions.

The combat power of these guys who rushed here was not weak, and they had reached the strength that was enough to kill the 6th and 7th order sub-monks of the Nirvana Realm of human monks.

However, a demon with such strength is no threat to Long Fei, even if it is a train of skins, it is not enough for him to kill.

Because of killing these weaker creatures, the spirit value obtained is relatively small, Long Fei actually has little interest in hunting them, Long Fei came to the Seven Heavenly Demon Domain controlled by Sheen this time, he planned to go to the Demon Cultivation Pool of the Seven Heavenly Demon Domain, try to destroy it, and see if the spirit value obtained is the same as before, as amazing.

"Boy, have you ever seen the appearance of blood food?" The demons who surrounded Long Fei, after arriving at the distance of about 100 zhang from Long Fei, stopped their pace of progress, and then the tiger-faced human monster led by the leader shouted directly to Long Fei.

The "blood food" in the mouth of the tiger-faced human demon refers to flesh-and-blood creatures such as humans, the blood of human beings and other creatures, and souls, which is a very rare and precious delicacy in the eyes of the demon.

"Didn't see it. Long Fei naturally knew what the tiger-faced human demon was referring to, so he hurriedly replied and shook his head in denial.

Long Fei's words fell, and a monster with an appearance that looked like a bat flapped its wings at great speed, instantly arrived in front of Long Fei, flew around him, and then trembled its wings slightly, hovering two meters above Long Fei's head, staring at Long Fei with those eyes that seemed to be able to pierce people's hearts, and at the same time shouted to him bluntly: "You lie, if my estimate is correct, you are the red-blooded creature who has just infiltrated my demon domain." ”

"You talk nonsense. Long Fei denied it.

"Stop quibbling. The bat-form monster smiled indifferently, then looked at Long Fei and said, "If you take a blow from me and take damage, it is not red blood that flows out, but demon blood, then we can believe that you are not a red-blooded being." ”

"I don't have the habit of being attacked innocently. If you want to fight, just say it, Lao Tzu is with you. Long Fei replied.

"You do have some guts, the cultivation of the 6th level of the reincarnation realm, you dare to argue with me, it seems that you are really tired of it. The bat-form monster pursed its lips, then flapped its wings, dodged out, and then flailed a pair of claws born in its abdomen and grabbed at Long Fei's head.

"Don't think that my cultivation level is low and easy to bully, since you are looking for death, then I will fulfill you. ”

Seeing that the bat-form monster refused to let go of himself, he felt a little depressed in his heart, but more annoyed, because he knew in his heart that once he made a move, his identity as a non-demon might be exposed, and if he didn't make a move at this moment, it would mean that he would be beaten, which would make him feel even more aggrieved in his heart.

Therefore, at the moment when the bat-form monster approached, Long Fei roared at the guy, and then without hesitation, he dodged lightly to avoid the attack of the bat-form monster's claws, and then directly performed the "Dragon Fist" technique, covering the head of the bat-form monster and smashing it down.

"Bang!"

The head of the bat-form monster was hit hard by Long Fei's punch, and its head exploded directly, and its body collapsed by the impact of the power surging out of Long Fei's fist, turning into a puff of demonic qi and floating there.

Then, without hesitation, Long Fei directly cast a spell, rolled up all the demonic qi, incorporated it into his body, and used the refining energy of the system to refine it and integrate it into his flesh and blood, improving the anti-demon attributes of his own flesh and blood.

"This guy is really an anomaly, kill!" Seeing that the bat-form monster was killed by Long Fei, he captured the power that emerged from Long Fei's fist, which was different from the magic power, but he didn't notice any abnormal power fluctuations, which made all the demons feel very puzzled in their hearts, but the leader of this group of demons didn't bother to care whether Long Fei was a real demon or not, and only wanted to kill him and avenge his brothers and companions, so he immediately issued an order to attack Long Fei directly to his subordinates at the moment when Long Fei killed the bat-form monster.

For Long Fei, killing one is killing, and killing a group is also killing.

What's more, the group of creatures in front of him are all monsters that cannot coexist with humans and other creatures at the same time, and Long Fei hunted them, and he had no psychological burden.

Therefore, in the face of the approach of a large number of monsters, Long Fei just smiled indifferently, and then without hesitation, he directly performed a large-area killing secret technique, releasing a powerful flame power, gushing out of his body, turning into a fire dragon, sweeping around, only engulfing all the space areas within a radius of ten miles. 10
