The giant beast's skull was eaten up. Except for the centipede in the skull that used this skull as a nest, there were no other creatures around it. Gushen turned around and crawled onto the top of the skull and saw that the thick horn was still there. Because the flesh and blood were eaten up, it had fallen off and stuck in the skull bone.

He climbed to the horn a few times, looked around and jumped around to the other side into the bone groove where the horn was located, rubbed his hands and held the huge horn with his hands, shouted and lifted it up suddenly, and the thick horn loosened and slid down. He immediately thought about it, and silently thought about collecting items when he slid down with the horn.

The next second, his hand lighted his eyes and his eyes were empty, and the horn disappeared instantly. He overwhelmed his head and turned it back and slid down into the cracks in the bone groove.

It slid into the skull a few times, followed an oblique bone slope and finally fell into the depths of the giant beast's skull. According to the head, it should be in the skull down the head and eyebrows, similar to the position of the purple mansion sea of ​​consciousness between the eyebrows.

It is not very deep. There is a ray of white light on the bone seam above the head. It can be seen clearly that this is a large closed bone cavity with no passage to other places. In this bone cavity that is about half an acre, a large round bone bead is embedded toward the forehead, with a diameter of about one meter and looks very smooth.

He tried to touch it gently, and the bone bead actually slid forward. There was a rumbling sound. The bone bead actually slid out like this, slid out in front of his eyes, falling from the forehead of the giant beast, and a huge muffled sound came from a "bang".

He immediately passed through the thick skull of the giant beast from the entrance of the bone bead cave and poked his head out. He saw that the thing smashed a big hole on the ground. The big red-shelled centipede crawled out at some point and was spinning around the bone beads.

Only then did he notice that the bone bead was located between the giant beast's eyebrows, with a single horn upwards and two huge eye sockets slightly downwards. I don't know which insect or ferocious beast the eye bead was eaten by it, leaving only the bone bead embedded in the eyebrows.

There should have been a layer of skin to protect it, but now the skin is gone, and it falls out as soon as you touch it.

Gu Xuan didn't know what this thing was, but it didn't prevent him from guessing that it was a good thing, or he could collect it first and find someone to check it out when he returned to the sect.

In fact, the entire skull of this giant beast is a good thing. Such a powerful skull can be used to refine it into a very powerful evil magic weapon. Some magic weapons of the evil sects are refined with powerful cultivators or monster skulls. The stronger the skull, the stronger the power.

Unfortunately, he can't take this thing, and the beast horn can be obtained through a bug, so the skull can't get it.

Moreover, the flesh and blood of the skull have been eaten up and left for so long, and the energy contained in the skull has long been gone, and nothing can be refined even if it is taken.

Of course, even if he gets it, he will not be able to cash out. Such a powerful giant beast's head is very valuable, but Yuanxu Immortal Sect is a genuine Xuanmen sect and does not have any evil secret methods to sacrifice and refine skulls. If sold to other evil sects, how to take action will be a big problem.

So even if he knows that things are good, he can't make use of them.

At this time, the centipede seemed to have found him on the skull. It was climbing upwards along the edge of the skull. Gu Xuan ran to the top of the centipede and squatted down. Looking at the centipede that was climbing upwards, he pinched his chin and rubbed it, and suddenly showed a strange expression on his face.

The ground flew up into the air, flew above the centipede, stretched out his hands and hugged him slowly, and thoughts moved, and the extremely thick beast horn appeared in his hands out of thin air. Then he sank and let go quickly. Under the corner of the beast horn, which was eighty or ninety meters long, a loud roar came from below, just like a missile slamming down, and a circle of broken soil was everywhere.

He slowly flew down from the skull of the beast, turned his head and looked down, and saw that the centipede had been hit by a thick piece under the beast's horn. It had turned into a pile of meat sauce that was invisible, with only the broken red carapace that proved its once existence.

"Hehe, this trick is good!"

Gu Xuan just tried it and it was really good. This made his thinking open a new world. This horn is eighty or ninety meters long, and the thickest part of the bottom is four or five meters in diameter. It is so heavy that it is so heavy that it can't be described as thrown from a high altitude and hit it.

However, the centipede was directly turned into meat sauce, so there is no need to expect the harvest.

Kill the centipede, Gu Xuan reached out and pressed the beast horn. With a thought, the huge beast horn disappeared instantly.

It was difficult to put away this thing in the first time, but once it could be put away, it would be put away as soon as it was touched next time, without any effort. Moreover, he only collected the horns of the beast. All the messy things in the centipede stained on the horns were stripped out and not collected at the same time.

Once the centipede died, there was no second centipede or other ancient insects inside. Gu Xuan took out the array plate to activate it and encapsulated the skull again.

He was not going to continue taking risks, but stayed here, and was going to use this giant beast skull to settle his home.

Of course, it is definitely not possible to just do this, so I have to make a little modification.

First, dig a large hole on the ground, make some broken soil and mud into mud, and fill some cracks in the giant beast's skull to avoid any crawling in, and then move some stone and soil to mix it into cement with the dirt, seal the giant beast's big mouth halfway, leaving only one door.

Although this small Xumi square inch formation can be opened all the time, he cannot be opened all the time. He must adapt to life in the prehistoric world, so as not to be able to survive without this formation plate.

Seal half of the bellies' mouth and cover it up with some plants. The broken neck of the bellies should be sealed, leaving only a small escape port to block it with a giant rock. Then check the bone chambers in the bellies' skull to figure out the situation inside the skull.

The skull of this giant beast is like a building, with many different spaces in the head, such as the largest brain space, cerebellum space, a space between the eyebrows, nasal space, orbital space, and even the space inside the bone marrow after it is dried up, etc. The head is big, and the space inside is naturally large. He has to figure it out so that he won't be chased by monsters and accidentally run away.

In the next month, after practicing every day, he took some time to organize his home, which he had probably lived in for many years. He built a little wall here every day, made a hole there, or went a little farther away to crush some grass leaves, and dried the broken grass fibers to use as a mattress.

A month later, Gu Xuan blocked the entrance of the cave and went offline.

Back to the real world of immortals, he continued to rush to the road and logged into the prehistoric world a month later.

After a few months, the skull was also well-designed by him. By the fourth time, the skull had been completely transformed.

On that day, he stood on the top of the giant beast's skull, stretched out his hand and a thin layer of clear light around him quickly contracted. The small Sumeru square inch formation was closed by him and turned into a formation plate and fell into the palm of his palm. Suddenly, a surging primitive spiritual energy surged like a tide.

Without formations, the spiritual energy was circulated, and he was directly exposed to the vision of all things in the vast world.

He raised his head and took a deep breath. Gu Xuan put away the array plate, shook a grass thorn more than two meters long with his hand, and showed up in his hand. He shook his grass gun and created seven or eight phantoms. As his wrists quickly turned, the grass thorn bent slightly out of an arc.

This was a kind of grass that he found when he climbed out of the pit to look for grass leaves. It happened that the three-blade wind musket was lost, so he picked a large number of thorns and temporarily replaced the gun to practice Liaoyuan gun technique.

The grass thorn is quite hard, but after all, it’s just the thorns growing on the grass, so it’s okay to practice, so you don’t have to expect to use it for battle. Gu Xuan didn’t expect to attract monsters everywhere for the time being. He didn’t even stay in the prehistoric world for a long time, and it only took about a month at a time. When the time came, it would be offline. The most important thing now is to return to the sect first.

He rushed so quickly that he finally saw Yuanxu Immortal Gate from afar, the precious light rising into the sky, the floating island faintly appeared in the clouds, and the sword light rising into the sky, which made Gu Xuan feel a urge to burst into tears.

He found a small river to take a shower, and he rushed around for a while. He hadn't taken a shower for more than half a month. Now he has a strong...male smell on his body.

But he was very energetic, not at all tired, his eyes were bright, his mental power was sufficient, and his true energy was even more sufficient.

After returning for half a year, he entered the prehistoric world five times. Even if he only stayed for about one month each time, he stayed for about half a year in total.

In the past six months, he did not take a step to the giant beast skull. He stayed there every day to practice. He insisted on practicing Qi for a big circle every day, devouring the remaining giant beast meat before refining his body for five days. In the past six months, all the accumulated beast meat was used up. The degree of body refining naturally increased. Now he is starting to refine the internal organs and sacrifice the internal organs.

As for the previous steps of skin refining, bone refining, blood refining, etc., we have been sacrificed and refined more than once.

These have been exercised to 100%, but Gu Xuan thinks this is not enough. He is still continuing to exercise while refining his organs. Now his progress has exceeded 150%.

Although it only increased by 50%, the increase is actually much more than 50%. Because after the progress of body refining in each stage reaches 100%, it is not only more difficult to go further, but the increase obtained in each step is correspondingly greater. For example, if you practice skin and tendons before, you will increase one kilogram of strength. After 100%, the increase may be two kilograms, or three kilograms or even more. As the progress is higher, the increase will naturally be higher.

This growth does not increase linearly, but geometrically, with the greater the increase as it reaches the later stage.

Gu Xuan also thought that after the subsequent body refining steps were completed, he would refine the giant beast pill to completely transform himself and become an indestructible body of Vajra in one step.

Although he is a little far from the Indestructible body of Vajra, his strength cannot be underestimated. Now, he has steadily entered the late stage of the fifth level of Qi Refining Heaven. There are a total of 195 acupoints. Compared to the eight acupoints that seemed to have only increased half a year ago, the progress seems very slow. But you should know that the center of gravity of the Qi Refining in the past is not increasing the true energy at all, but is constantly refining the acupoints that have been opened in the past, constantly enhancing the true energy of the original acupoints, and has increased the true energy in all the acupoints from twelve drops to fourteen drops.

Therefore, the cultivation level does not seem to have increased much, but the total true energy has increased by a large part.

Although the small thick earth meridian he practiced was ordinary, he could not resist the abundant spiritual energy in the chaos, and had a powerful body to carry more true energy. In fact, this was not the limit of his physical acupoints. According to Gu Xuan's estimate, even if it is his current physical body, each acupoint can withstand twice the true energy of the current true energy.

Moreover, the more his body will become stronger and stronger. When he becomes the indestructible body of Vajra, the true energy that his body can carry will reach a level that ordinary monks will be stunned. At that time, he can kill any opponent who is not higher than his own realm by relying solely on his own strong true energy.

In the way of cultivation, the role of true essence is very important and is the cornerstone of one's ability. However, this is only one of the decisive factors of personal strength. To become a true strong person, relying solely on strong true essence is not enough. There must be mysterious methods and powerful magic weapons.

Of course, if you don’t have enough cultivation, you will definitely not be able to become a strong man. Even if you give you mysterious martial arts and powerful magic weapons, you will not be able to activate it without enough cultivation.

Cultivation is the basis of cultivation and the guarantee of strength. To put it in a slogan that Gu Xuan once saw in a elixir that increased his cultivation in a elixir in a elixir in the market - with strong true energy, you will be half successful!

In just two years of entering the school, he has opened up and condensed 195 acupoints. Each acupoint has fourteen drops of true energy and has a strong cultivation level. Such cultivation is definitely unique among the outer sects. Even if it is included in the same training period for all the inner room disciples, he is considered to be the best, second only to those super geniuses.

Gu Xuan could already predict that when the sect competition was small, there would definitely be a group of senior elders in the sect accepting him as disciples.

In fact, Gu Xuan had already made plans. When he returned, he immediately asked Lei Yu to find out the information about the elders of the inner sect of Yuanxu Immortal Sect and other senior officials, and then he would like to be a good master.

In the world of immortal cultivation, if you are willing to be a good master, you are not reluctant to marry a woman. There is a huge gap between a master of a Niu Bi and an ordinary master. Even if he can enter the inner sect and his cultivation is good, he naturally wants to be a good master.

With his rebirth in the Earth Immortal Realm and the super cheating device of the Prehistoric World, Gu Xuan's ambition in practice naturally increased. He used to just live longer, but now he wanted to go further. Although the Prehistoric Realm could allow him to obtain various treasures and rare resources that were difficult to obtain in the Earth Immortal Realm in the future, he could not help in his martial arts and magical powers. This still depends on the sect and a powerful master.

He took a shower in the river and cleaned it. He casually put on a piece of clothes he bought when he passed by the Mortal Town on the road. He set up a white cloud and flew towards Yuanxu Immortal Gate.

The closer he got to the immortal sect, he became a little nervous. He didn't know if Guan Qiang would return to the sect first, and the evil ones would complain first, which would be a little troublesome.

However, when he came to the mountain gate, he passed through the formation barrier at the mountain gate, and was not expected to be ejected. This means that the sect law enforcement hall did not blacklist his identity card, which made him feel relieved.
