After another ten years of retreat, Mu Sheng's skull space grew from 11 zhang to 12 zhang in size.

In the process of carefully cultivating the skull space, Mu Sheng also discovered some tricks, if the creatures in the skull space are artificially killed, the anger and resentment generated by the creatures cannot be absorbed by the space, these resentments and resentment will accumulate in the space, and when the resentment and anger accumulate to a certain extent, undead creatures will be formed, and the reason why these undead creatures can come back from the dead is because they have encroached on the vitality needed for the growth of the space, and these vitality are released by other creatures before they die.

Therefore, when buying spirit beasts and putting them into the skull space, killing and releasing soul power and life force, nourishing the skull space, while also releasing anger and resentment, these resentments and resentment are less, and there is no problem, but when they accumulate to a certain extent, there will be big problems.

The current skull space is still in the initial stage of growth, so it is naturally not suitable to be forcibly lifted in this way.

Therefore, in the past ten years, Mu Sheng has planted spirit sprouts to upgrade the space, although the space must be nourished by the soul of the creature in order to form the will power of the world, but these souls must be souls who died peacefully, and the souls that were killed have strong resentment and anger, and cannot play a role in nourishing the space.

How to let creatures live peacefully in the skull space for a lifetime, and can form a complete biological chain is a problem that Mu Sheng needs to solve, but unfortunately this problem has not been solved at all.

Since the last time he engraved the Sun True Fire Rule Spell of the Innate Fire Spirit-Three-Legged Golden Crow, after 20 years, his soul has been able to engrave the rule spirit pattern of the next Innate Five Spirits under the day and night improvement of the soul spell, so it seems that it will take about 20 years to cultivate enough soul strength to engrave a complete law spirit pattern.

After Mu Sheng's soul strength was sufficient, he engraved the spirit pattern of the innate water spirit in the sea of consciousness to form a complete water system law spell, and this spell pattern also formed a black villain after absorbing a large amount of Mu Sheng's soul power, flying into the aura origin and doing opposite to the fire spell pattern of the red villain, and cultivating cross-legged.

20 years is not a long time for a 5,000-year-old infant monk, not to mention that Mu Sheng has an extra 1,000 years of lifespan because of the innate supernatural power of the origin of the aura.

......

A hundred years have passed in a hurry, Mu Sheng has been completely engraved with the law of the innate five spirits, when the last gold law spell inscription is completed, the villain who turned into white did not enter the origin of Mu Sheng's aura, when the five most basic aura law spells of gold, wood, water, fire, and earth were formed, the villain formed by these five law spells is in the direction of the five elements around the origin of the aura: gold in the west, wood in the east, fire in the south, water in the north, and the earth dwells in the center.

The five laws of the innate true spirit continue to highlight the true spirit qi input into the aura source, the aura origin white, black, yellow, green and red five colors gradually fused into a gray aura, nine hundred and eighty-one days later, the five-color aura source completely turned into a gray gray dull aura mass.

Seeing this gray aura mass, the five innate true spirits with tired faces instantly submerged into the gray air mass.

Mu Sheng sank his consciousness into the gray air mass, and found that the entire air mass was as faint and dim as the appearance, and the five innate true spirits all closed their eyes and absorbed the gray spiritual light.

At the same time, a stream of thought fed back to Mu Sheng, and it turned out that this gray aura light cluster was the source of the primordial being.

The beginning is Wuji, the beginning gave birth to two instruments, two instruments gave birth to three talents, three talents gave birth to four images, and the four images gave birth to five elements, and the five elements evolved into all things.

The five innate spirits, through the combined force of 81 days, return from the acquired to the innate and from the five elements to the primordial.

After the formation of the primordial source, Musheng's natural supernatural power was promoted, and the primordial source could not bring any benefits to Musheng, in the past, the aura origin could provide a steady stream of mana for Musheng, but now Musheng's mana is only deeper than the general primordial infancy, to say that the only role of the primordial source is to evolve the origin of the world, if Musheng can't evolve the origin of the world, then it is hopeless to become an immortal.

The innate supernatural power of the primordial source is a big cake for the current Mu Sheng, although the future is very beautiful, but the future and twists and turns, the difficulty is very high, how to evolve into the origin of the world?

This made Mu Sheng's head big for a while. When encountering problems, it is natural to find information, so Mu Sheng, who has been in retreat for a hundred years, has to go out of the customs, read hard in the library day and night, and search for 30 years without results, although these 30 years of rummaging through the library have not found anything about how the origin of the primordial origin advanced to the origin of the world, but Mu Sheng has increased a lot of knowledge.

The library couldn't find the relevant information, and originally wanted to use the connections to find the information of the origin of the primordial, but in the end he gave up, among the people he knew, except for Qian Duobao, he might have knowledge in these aspects, but as the grandson of the Great Elder of the Xiuzhen Alliance, he was well-informed, in case he saw through it, maybe he would be in danger, even if Qian Duobao was harmless to people's hearts, who knew what kind of temperament his elder grandfather had?

So it's better to be cautious, and wait for the opportunity to find a way to solve it later.

Three hundred years have passed in the blink of an eye, and Mu Sheng, as a combatant, is faced with a choice, one is to buy the soul fragments of the law to absorb the perception and advance to the Mahayana period, and the other is to become a logistics personnel.

Mu Sheng finally turned into a logistics staff, and as a logistics staff in the Yuan infant period, he was generally the inspector of the town guard.

After the Xuanyuan World defeated one world and plundered the origin of the world, the aura of the entire world disappeared and became the lowest energy level.

The former monks will also become mortals with the disappearance of the aura, of course, this is without the replenishment of the spirit stone, and the important materials for the monk's war will naturally be plundered by the victorious side.

The Inspector is the highest combat force set up by the Xiuzhen Alliance to suppress the rebellion of the invaded world.

Although the world's aura disappears, after the monk closes his aura, the loss of aura is still extremely slow, and the monk in the infancy stage only needs a low-grade spirit stone every month to ensure that the body is at its peak state and make up for the loss of aura.

When it is necessary to fight to unseal the aura, you can rely on the large number of spirit stones prepared by the Xiuzhen Alliance for the supervision envoy in advance.

For those worlds without aura, there is no difference between releasing a Yuan Infant Spell and an atomic bomb explosion, it is completely the peak combat power of the destruction level.

The world that Mu Sheng wants to guard is a colony called the First God World, after the encroachment of the Xuanyuan Continent, the world origin of the First God World, the people of the entire continent are planting ordinary plants, and then raising all kinds of ordinary livestock, and after the livestock is slaughtered, they absorb blood energy and soul energy. After the soul energy is purified, it is made into blood beads and soul beads to attack the Xuanyuan world, the blood beads have a wonderful effect on repairing injuries, as long as there is enough blood energy, the monk's heart and head will not die if they are intact, and the injuries can be repaired instantly, the soul beads can allow the monks of the alliance to continuously replenish the soul energy, the replenishment of this soul energy is of great significance to the Xiuzhen Alliance, the Mahayana period or the immortal realm monk who comprehends the law needs to replenish a large amount of soul power after stripping the soul fragments of the law, and the immortal realm monk who dies in the battle of the world not only needs a large number of blood beads but also a large number of soul beads, and the Mahayana practitioner is generally immortalAfter the physical body is destroyed, a large amount of blood and qi energy is also needed to reshape the physical body.

Therefore, these colonial worlds are of great significance to the Xiuzhen Alliance, and there are not enough supervisors in the Yuan Infant Period every year, so this time Mu Sheng was directly sent to the Origin God World as a supervisor for a period of 100 years.
