Although it takes a relatively long time to practice the Heavenly Vein Treasure Body exercise with the power of the star core, this is the safest choice for Long Fei, and he does not have to risk his life to be beaten.

Arriving in the depths of the Emperor Star, after Long Fei sensed that the oppressive power given to him by the power of the star core had reached its limit, he immediately sat down there cross-legged and entered the state of cultivation, practicing the "Suppression of Prison Sutra" exercises and the "Reverse Blood Transformation Demon Technique", and patiently waiting for the "Heavenly Vein Treasure Body" technique to upgrade.

In this way, Long Fei continued to practice in the depths of the Emperor Star for half a year, until he reached the deepest core level of the Emperor Star, and the oppressive power of the underground space of the Emperor Star did not have any sense of pressure for him, so he stopped cultivating.

After half a year's hard work, Long Fei has cultivated the "Prison Suppression Sutra" and the "Reverse Blood Transformation Demon Skill" to the same level as the system level 96, and others will know that his cultivation realm has reached the 6th level of the reincarnation realm through exploration.

For Long Fei, the "Prison Suppression Sutra" exercises and the "Reverse Blood Transformation Demon Technique" exercises were just auxiliary exercises for Long Fei, used to disguise his identity and act conveniently, which was not very helpful to his actual combat ability.

Even so, Long Fei did not give up these two auxiliary exercises, and still continued to practice.

Because in his opinion, only by truly cultivating these two auxiliary exercises to a higher level can he feel a sense of security in his heart, and feel that this is his real strength, unlike after the system level is improved, although his combat effectiveness has increased, he himself has no feeling of strength improvement, which makes him feel less at ease.

In fact, Long Fei did this because he was on guard that if the system suddenly disappeared out of thin air one day, he would not become nothing, at least the power he had gained through the cultivation of the "Prison Suppression Sutra" technique and the "Reverse Blood Transformation Demon Technique" technique was still there.

In the past half a year, the biggest gain is defense, because he took advantage of the oppressive power in the depths of the Heavenly Emperor Star to directly cultivate the "Heavenly Vein Treasure Body" technique to the 12th level, which means that on the original basis, he has directly improved by 5 levels.

In this way, Long Fei's defense is strong enough, even if he encounters a terrifying figure of the 4th level of the Chaos Realm, he can save his life if he is hit by it.

You must know that Long Fei's current system level is only level 96, which is equivalent to the strength of the 6th level of the Reincarnation Realm, and there is also a big level of Nirvana Realm in between.

If others knew that Long Fei's defense was so terrifying that they directly crossed a large level to resist the enemy's attack, their jaws would drop in surprise.

"Half a year of hard work, the harvest is good, the power of this Emperor Star's star core is so strong, I don't know if I can refine it with my current system level. Standing in the depths of the underground space, looking at the sight floating there, looking from afar, just like the heart of a human being, in the very rhythmically beating core of the Emperor Star, Long Fei took a deep breath.

Although the defense was strong enough to withstand the oppressive power released by the star core power of this planet, Long Fei felt that he was standing in front of this star core, and he actually felt a sense of daunting, which made him not have much hope for him to use the power of the system to refine the huge star core in front of him.

"Whoosh!"

Long Fei dodged and approached the star core.

Then, no longer hesitating, he immediately cast a spell to urge the refining power of the system, turning into thousands of tentacles, and extending directly towards the star core.

Getting closer and closer to the star core body, Long Fei vaguely noticed that the speed of the extension of the refining power seemed to be hindered, becoming slower and slower, until Long Fei urged the power to the extreme, and the refining power that extended to the star core also came to an abrupt end.

"The refining power of the system can't even penetrate the protective layer released by the star core itself, and it still refines a yarn. It seems that if you want to refine the star core of this Emperor Star, the only way to go is to upgrade the system level first. After several attempts, the result was the same, the refining power released was not able to penetrate the protective layer of the star core, and Long Fei finally chose to give up.

Since he couldn't refine the star core of this planet, it was naturally unrealistic for him to want to kill the enemy at a higher level on this planet.

Although this result made Long Fei feel a little helpless, he didn't bother to think about it, so he quickly left the underground space of the Emperor Star and returned to the surface of the Emperor Star.

Long Fei was not very familiar with the differences between the various forces on the Emperor Star, and he didn't pay too much attention to it, so he casually chose a nearby city and rushed over directly.

Getting closer and closer to the city in his sight, the majestic and tall city gate came into view, and Long Fei knew that the huge city he wanted to go to was called Xueyang City.

In fact, Snow Yang City is the largest ancient city on the Emperor Star and is home to the headquarters of the Luo family.

The other cities, although not as large as Snow Yang City, are still several times larger than the cities on the Nile planet.

Long Fei didn't know that Xueyang City was the headquarters of the Luo family, and he didn't care about this, because he had changed his appearance at the moment, and he looked very different from his original self, and he felt that even if he met a powerful and terrifying super master, it would be difficult to see through his disguise and see his true face and image.

Flying to a position about ten miles away from the gate of Snow Yang City, a group of patrols riding flying war beasts rushed over, led by the general in silver armor, immediately pulled his throat and shouted to Long Fei: "You are about to enter the airspace of Snow Yang City, please land quickly and enter the city on foot." ”

"Snow Yang City is forbidden to fly?" Long Fei stopped and asked with a frown.

"That's right, this is the rule of Snow Yang City, and anyone who breaks it will be severely punished. The silver-armored general responded.

"......" Long Fei was speechless, and he didn't bother to say anything more, so he flew down, and then walked slowly towards the gate of Xueyang City.

When I was in the air before, I looked down at the gate of Snow Yang City and felt that the gate was not so magnificent.

After the dragon flew to the ground, he saw what it means to be spectacular.

Because when he was about 500 meters away from the city gate, he was surprised to find that he couldn't see the top of the city gate when he looked up, but saw that the top of the city gate was connected to the sky, and on the left and right, it was impossible to see the edge at a glance.

"It's a big city. Long Fei sighed in his heart.

Soon, Long Fei arrived at the city gate, and was immediately stopped by the soldiers guarding the city gate, and was told that he had to pay a fee of 10 million spirit crystals to enter the city.

Although 10 million spirit crystals were nothing to Long Fei, because he had countless materials in his inventory, casually taking out the smallest storage bag of items was enough to be worth 10 million spirit crystals.

But let him give it so directly, as a fee for entering the city, I still feel a little unhappy in my heart.

"Can there be less?" asked Long Fei with a frown.

"This is the lowest price, if you talk nonsense, you will have to pay 50 million spirit crystals to enter the city. The soldier's gaze stared at Long Fei for a moment, and then he replied with a sneer.
