Fighting hard with Long Fei, although it was just a casual and ordinary move, Luo Biyan immediately judged from it that there was a certain gap between his strength and the indigenous in front of him, and if he continued, even if he tried his best, he might not be able to get benefits.

So, Luo Biyan's gaze stayed on Long Fei for a while, as if he wanted to remember and imprint his face into his mind thoroughly, so he didn't even say a word, and left in a gloomy manner.

"Before he left, he made a feud with the monks outside the territory. ”

"But it doesn't matter, if you make a feud, you will make a feud. It was his own rudeness that came first, and if he insisted on seeing me as an enemy, I would have to deal with it passively. ”

"It's just that what makes people feel speechless is that this guy's strength is obviously much stronger than that of the Red Sky Demon Lord and others, but the power of heaven and earth on this Heavenly Pluto Star doesn't reject him?"

"Could it be that he has a treasure on him that can shield the power of the heavens and the earth?"

"Such a master, being able to enter and exit the Pluto Star freely, this is not a happy thing for the creatures on the Pluto!"

"If after I leave Pluto, such a powerful person comes to Pluto to make trouble, then the creatures on this planet will only be enslaved!"

Long Fei originally thought that after dealing with Yin Gengyu and the people from the Demon Domain, Pluto would be at peace forever on this day.

After today's incident, Long Fei realized that things were far from what he expected.

It was only at this time that Long Fei really knew that the natural protective strength of this Heavenly Pluto was far worse than what he thought in his heart, and his strength was slightly stronger, as long as he knew the specific coordinates of this planet, as well as the treasures that carried the power of shielding the planet's heaven and earth, he would be able to enter and exit freely.

So, at this moment, Long Fei fell into deep thought, thinking about what to do in order to increase the self-protection of Pluto.

After thinking for a while, to no avail, when he saw Luo Biyan's figure disappearing from the scope of exploration, Long Fei left and returned to the Great Hall of the Flying Dragon Castle.

As soon as Long Fei returned to the main hall, everyone cast their eyes on Long Fei, as if they wanted to learn from him about the sudden arrival of the young man, but no one dared to speak easily.

Liu Xiaomeng, who was more familiar with Long Fei and was the deputy castle master of Feilong Castle, saw through everyone's thoughts, so he didn't hesitate at all, and immediately asked Long Fei: "Castle master, who is that young man?"

"A young master from outside the domain has come to investigate the destruction of the Demon Breeding Pond in the Demon Domain. Long Fei responded casually, and then bluntly asked everyone present, "Have you ever heard of any method that can improve the planet's protection ability and resist the infiltration of any extraterritorial person?"

"What do you mean by this, Castle Master, are you worried that there will be an invasion of the Heavenly Pluto by a foreign master, which will be detrimental to the creatures on my Heavenly Pluto?" asked Liu Xiaomeng.

"yes. There are too many powerful masters outside the territory. If you don't take precautions, if another guy like Yin Gengyu comes to the Heavenly Pluto, it will bring great trouble to the creatures on the Heavenly Pluto. I hope to find a way to use the power of heaven and earth on the planet to defend myself against extraterritorial monks and prevent any extraterritorial beings from setting foot on the Heavenly Pluto. Only by doing so can Pluto be truly safe on this day. And the many creatures on the Pluto can truly practice and live their lives with peace of mind. Long Fei nodded.

After listening to Long Fei's words, everyone present was silent.

Because these people are not as far as Long Fei thinks about, and their abilities are limited, even if they want to do this kind of thing, they are more than willing to do it.

The scene was silent for about a minute, Long Fei thought that there could be no gain, and when he was about to speak, the ghost spirit on the side seemed to remember something, and hurriedly said directly to Long Fei: "The master can try to refine the star core of this star, and control the powerful power contained in this planet, so as to arrange a powerful barrier defense array." In this way, it is not so easy for people from outside the territory to want to enter. The only disadvantage of this is that once the monks inside the planet are strong, if they leave the planet and want to return, they can only enter by applying to you to obtain the qualification to enter the interior of the barrier defense array. If there are more powerful monks in the future, it will be very frequent to enter and exit the Heavenly Pluto Barrier Defense Array, and it will be a very troublesome thing for you. ”

"It's easy to do. Long Fei replied with a smile, "If there is really a day, then I will directly set up a rule, but any monk whose strength has reached a certain point and hopes to cultivate outside the territory, once he leaves, he will be forever forbidden to step into the Heavenly Pluto." ”

"Hmm...... That seems to work. The Phantom replied.

After learning through the conversation with the Phantom Spirit that he could also control the power of the planet by refining the star core, and then use the power of the planet to arrange a blocking defense array to block outsiders, Long Fei immediately handed over the matter of presiding over the celebration to Liu Xiaomeng, Lao Xuangui and others to take full responsibility, and he left the Flying Dragon Castle and went to the Sanctuary Academy, Tianlong Academy, Vantage Academy and other forces to study, hoping to find a way to find the planet core and refine the planet core from the data storehouses of the three universities.

It's just that Long Fei's efforts have not received any effect.

Despite this, Long Fei still obtained some information related to the core of the planet by reading a lot of materials, and knew that the planet is divided into stars, planets, comets and so on.

After gaining knowledge related to the planet, knowing that if you want to find the planet's core, you need to go to the deepest core layer of the earth before it is possible to touch the core of the planet, and after trying to refine it, Long Fei did not hesitate at all, and immediately set off to perform the "Earth Escape Technique" to travel through the underground space at high speed, and went straight to the core layer of the planet.

After passing through the soil and rock layer of more than 3,700 miles, Long Fei clearly felt that the oppressive force on his body was increasing at an extremely fast speed.

In addition to the oppressive power from within the planet, there is also a powerful mysterious power carrying nine attributes, which radiates from the depths of the planet and exerts on his body, making the power he bears increase layer by layer.

Passing through the soil and rock layer is the magma layer.

The temperature here is extremely high.

If it weren't for Long Fei's resistance to fire attribute power, which had reached the ground-level level, I am afraid it would be really difficult to resist, and at this level, it would have to stop.

Traveling nearly four thousand miles down through the liquid magma layer, Long Fei clearly sensed that the oppressive force from the depths of the earth's core had risen to a point that he could hardly bear, and if he continued to go deeper, then his flesh and blood might be crushed into a meatloaf by the powerful oppressive force.

At this time, every time Long Fei continued to probe deeply, a voice prompt message from the system would come from the sea of knowledge, telling him that the experience value of the "Earth Vein Treasure Body" exercise was increasing.
