Long Fei is self-aware, through the fight with the strange bird, he knows that his combat power is insufficient, and it is simply unrealistic to hunt a large number of powerful creatures in a short period of time and obtain enough spirit points to improve the level of the system.

Therefore, Long Fei suspended the killing of the creatures on the Savage Star, and instead chose to enter the depths of the underground space, first try to see if he can refine the star core of the Savage Star, and then use the power of the star core to assist in the battle, so as to deal with the creatures whose combat strength is not much different from that of the strange bird.

In this way, the speed of hunting will increase exponentially, and the efficiency of accumulating and harvesting spiritual points will naturally increase a lot.

The Savage Star and the Stellar Star, from the outside, seem to be almost the same as the individual, but in fact, the overall mass of the Savage Star is many times that of the Stellar Star, which Long Fei has a clear perception from the moment he drills into the underground space.

Because after he went deep into the underground space of the Savage Star, he obviously felt the oppressive force from the depths of the underground space, which was much stronger than when he went deep into the underground space of the Stellar Star.

However, such a little oppressive force did not pose much of an obstacle to Long Fei for the time being.

When he was about three million miles deep into the underground space, Long Fei realized that his body's endurance capacity had reached its limit, and if he continued to go deeper, he would be crushed to pieces by the terrifying oppressive force that existed in the underground space of the Barbarian Star.

Long Fei knew that this place was still very far away from where the star core was, and if he didn't raise the level of the Immortal Divine Body in time, it would be unrealistic to go deep into the location of the Savage Star Core smoothly.

Therefore, Long Fei did not hesitate, and immediately sat cross-legged in the same place, and began to cast the secret method of gathering immortal divine power, collecting the immortal divine power that existed in the depths of the underground space of the Savage Star as an auxiliary practice of the "Immortal Divine Body" exercise.

As the exercises for gathering immortal divine power began to operate, Long Fei was surprised to find that the concentration of immortal divine power filled by the underground space of this planet was much higher than the concentration of immortal divine power he had absorbed when he performed the exercises in the space-time channel, and it was more than enough to assist in the cultivation of the "Immortal Divine Body" exercises, and he suddenly felt very happy in his heart, and the idea that he was still worried that the immortal divine power existing in this underground space would be relatively thin disappeared in an instant.

Because the Immortal Divine Power is relatively abundant, the experience points obtained by cultivating the "Immortal Divine Body" are relatively large.

According to the frequency of the beating by looking at the data on the personal attribute panel, Long Fei felt that after some calculations, he felt that he needed to continue practicing for a week before he could improve by one level.

This kind of improvement speed is already quite fast for the current height of the Immortal Divine Body exercise.

Therefore, in the following time, Long Fei did not move his nest and left, but immersed himself in the state of practicing the Immortal Divine Body.

A week passed......

A month passed......

A year has passed......

It wasn't until two years passed that Long Fei stopped practicing the exercises.

Because after two years of cultivation, this "Immortal Divine Body" technique has been upgraded to a full level.

To his surprise, when he practiced the "Immortal Divine Body" exercise to the full level, the system did not give him any more prompt information to practice the new exercises, which means that Long Fei has reached the limit requirements of the system in the cultivation state of the flesh and blood body, and the flesh and blood body has directly turned into an immortal god body, which means that the current Long Fei, defense and vitality, have entered a new level, as for whether there is anyone in this world who can kill him by using anti-heaven means, this is unknown for the time being.

"The body has turned into immortal, even if it is attacked by a powerful and terrifying force, the flesh and blood body is shattered, turning into countless particles of dust, as long as there is a grain of dust that is not extinguished, then I can quickly recover from the state of the collapse of the flesh and blood, this is the power of the immortal god body. With the current state, it should be able to easily carry the oppressive power in the depths of the Savage Star underground space and reach the core. ”

Long Fei slowly opened his eyes, exhaled a long breath, and then got up, moved his body, and then stopped staying, and then dodged and swept out, heading straight to the underground core.

In the process of coming, Long Fei was surprised to find that the originally heavy and incomparably oppressive force was like a gentle breeze blowing on him at this moment, which did not bring the slightest obstacle to him at all, and this feeling lasted until Long Fei saw the star core of the Savage Star, and it never disappeared.

This also means that the oppressive power of the star core of a planet like the Savage Star has completely failed against him.

Previously, when Long Fei was refining the star core of the Stellar Star, because the system level was low, he failed to refine the Stellar Star Core.

Now that the system level has been increased to level 129, it is equivalent to the cultivation realm reaching the 3rd level of the eternal realm, coupled with the fact that he has cultivated into an immortal god body, and his abilities have been improved in all aspects, which makes Long Fei's refining of the Savage Star Core particularly smooth.

Half a month later, Long Fei refined the Savage Star Core as he wished, and obtained the permission to control the power of this planet.

And the benefit of refining the Savage Star Core directly to Long Fei is that the gray planet nodes on the "Ten Thousand Star Array Map" in the Sea of Knowledge have lit up a large area, and they are only missing the 9 gray planet nodes at the core and edge of the array map before they are all lit up in the end.

In Long Fei's system backpack space, Xiao Siqi, who was communicating with Long Fei's wisps of divine thoughts, suddenly noticed a feeling of dizziness in her mind, and she immediately realized that this was the ancestor of Tianque Palace, who had lost her patience, and used secret methods to summon her, so she hurriedly said to Long Fei bluntly: "During the time I have been with you, I have always been in a good mood, and there is a trace of sweet warmth, this strange feeling is something I have never had before." Thank you for chatting with me and having a great time in the past few years. Right now, the master has sent me a summons message, and I have to go back to the master and give him an explanation. ”

"You failed to complete the task he gave you, and you will be punished for returning just like that. Long Fei said.

Long Fei knew that if Xiao Siqi was not allowed to leave, the vicious Heavenly Gate Palace Ancestor would have hundreds of means, casting secret methods, torturing Xiao Siqi, and even directly controlling the operation of the self-destruction runes that he had placed in Xiao Siqi's sea of consciousness, thus destroying Xiao Siqi's consciousness and turning it into an empty shell that lost his soul.

Therefore, hearing that Xiao Siqi said that he was leaving to return to the division, Long Fei felt very depressed in his heart, and he couldn't wait to immediately kill the Tianque Palace and destroy the hateful Tianque Palace Ancestor.

But he understands that now is not the time to be impulsive.

"It doesn't matter. Xiao Siqi said with a smile.

"What the ancestor of Tianque Palace wants is the secret method of gathering immortal divine power, in order to prevent him from getting what he wants and punish you, I will teach you the secret method of gathering immortal divine power, so that you can confess to him when you go back. ”

Long Fei said, directly casting a spell, condensing the secret method of gathering immortal divine power into a knowledge rune and teaching it to Xiao Siqi.

"Thank you for thinking about me. I remember your kindness. Xiao Siqi responded with a smile, and then asked Long Fei to give her a ride, leaving the dangerous Savage Star atmosphere, and after entering the interstellar route, she took the flying treasure when she came to the Barbarian Star and headed for the Stellar Star.
