Huaxu World, the land of death.

Around the place of death in Huaxu World, all defensive formations have been established by the Xiuzhen Alliance, and the defensive formations have two main functions, the first is to prevent the invasion of undead creatures such as zombies and ghosts. Second, prevent the creatures of Huaxu World from straying into the land of death. Wise humans will certainly not run to the land of death to find death, but birds and beasts are not, and their intrusion into the land of death can not only increase the strength of zombies and ghosts, but also increase the number of undead creatures. Therefore, the Xiuzhen Alliance spent material, manpower, and financial resources to build such a large defensive array.

To tell the truth, this defensive array can't last long, Huaxu World is slaughtering a large number of spirit beasts every day, the anger and death qi produced by these spirit beasts are increasing, these negative energy encounters the large array maintained by the aura, it will definitely produce a positive and negative neutralization reaction, and the defense array will soon be corroded and melted by a steady stream of dead energy.

Well, the positive and negative neutralization reaction is one of the purposes of Mu Sheng's visit to the Land of Death this time, and the other purpose is to figure out how zombies, ghosts and other undead creatures are "double cultivated" with the Land of Death, that is to say, how the undead can increase the development and growth of the Land of the Dead, and how the Land of the Dead helps the undead grow, as long as this problem is clear, the biological chain of the undead can be destroyed, and then the Land of the Dead can be destroyed.

Things in the world can be divided into two aspects, yin and yang, such as the black sky and day, the sun and the moon, men and women, all of which are typical representatives of the two aspects of yin and yang. Only the harmony of yin and yang can promote the development and growth of things. The solitary yin does not grow, and the solitary yang does not live, which is the most basic law of the cultivation realm. Through decades of continuous experiments, Mu Sheng believes that death qi is a kind of yin attribute energy, and the yang attribute energy of aura is also the relationship between yin and yang, so zombies, ghosts and other undead creatures have to suck the essence blood or aura of creatures to survive. Of course, these are only speculations on the results of Mu Sheng's foundation experiments, and this trip to the Land of the Dead, Mu Sheng needs to continue the experiment to verify the authenticity of the results.

Mu Sheng released the five elements of zombies, in addition to the fire zombies left behind to protect themselves, the other four elements of zombies, all sent out, deep into the land of death to catch zombies or ghosts. Mu Sheng, under the protection of the fire zombies, wanders around the edge of the land of death.

Mu Sheng found that the land of the dead is basically full of ghosts, and zombies are extremely rare. Think about it, undead creatures also have a lifespan limit, and the defense array of the Xiuzhen Alliance is not a decoration, and without the source of corpses, zombies naturally cannot be formed. The ghost is a yin attribute energy body, and where the dead qi is strong, the ghost will be bred, and it can be said that the ghost is similar to a kind of aggregate of negative emotions and negative energy such as death and anger, and the low-level ghost has no wisdom at all, and acts entirely on instinct.

There is a fire zombie protection who has comprehended the complete version of the true fire of the sun, and these low-level ghosts naturally dare not approach Mu Sheng. Low-level ghosts who act completely according to instinct can feel the power of fire zombies even more, although they are attracted by the breath of Mu Sheng, a living person, but in the face of food, their own lives are more important.

The death qi in the place of death is naturally very strong, staying here, you will consume intense aura every moment, and only by releasing the aura can you avoid the death qi from invading the body. But the release of aura will be constantly eroded by the dead air, the consumption of the aura is very serious, and there are thick black dead clouds floating over the land of death, these black dead clouds cover most of the sun's rays, in the Huaxu world, there is no aura space, Mu Sheng's most important aura source is to use the sun's true fire law to absorb the sun's rays and convert them into aura, so the sun's rays are mostly blocked, and the source of Musheng's aura replenishment is reduced, so naturally they will not release their own aura to resist the erosion of dead gas, but order the fire zombies to help themselves resist the dead gas. For the fire zombies who have been playing with death gas since birth, they can naturally control the death gas well, and Mu Sheng has no worries and can rest assured to investigate the surrounding situation.

Mu Sheng walked around for half an hour, but he didn't see a single zombie, which shows the rarity of zombies, it seems that the defense array of the Xiuzhen Alliance is very effective, and the low-level zombies formed before are estimated to be old and dead, as for the high-level zombies, they will naturally not be seen on the edge of the land of death.

The zombies of gold, wood, water, and earth who went out to catch the undead also returned, and each zombie brought a dozen ghosts, which were intended to be used for attribute experiments. Mu Sheng speculates that in the Land of Death, the only things that can be naturally stored are fire-attribute undead creatures that absorb earth qi and sunlight, and the verification method is also very simple. Undead creatures with earth and fire attributes absorb earth or fire from the sun's rays every day. Just circle these zombies and wait slowly.

Oh, under the pressure of the Five Elements Zombies, these dozens of ghosts honestly stayed in place, time passed slowly, three days later, Mu Sheng found that this batch of ghosts were all fire-attribute ghosts, and at noon they would absorb a small amount of fire-attribute aura from the sun's rays to maintain life. There is no ghost with earth attributes, why?

Mu Sheng ordered the Five Elements Zombies to kill all these ghosts, and after the ghosts died, the dead energy of the body returned to the place of death. Mu Sheng remembers that when he was doing experiments in the Supervision Hall, after the zombies died, the dead qi would disappear, why did the dead qi in the bodies of these ghosts return to the place of death?

Mu Sheng thought of the ordinary zombie experiment again, ordinary zombies do not store death qi in the meridians, but directly use death qi to transform their bodies, and correspondingly only need to absorb blood to survive. Could it be that flesh and blood are a pair of positive and negative energy bodies like death gas? So the flesh and blood of zombies will neutralize part of the death qi, so the neutralized death qi will disappear after the zombie dies?

This idea also needs Mu Sheng to prove through experiments, how can the dead qi as negative energy be combined with the aura of positive energy to cultivate? The combination of men and women produces civilization, you must know that without men or women, human beings would not exist, so the solitary yin does not last, and the solitary yang does not live. It seems that the cultivation method of combining yin and yang attribute energy is very necessary to experiment, and it may be very rewarding.

Mu Sheng sent out four other lines of zombies except for the fire zombies to continue to capture the undead, and the results of this experiment were all fire attribute ghosts. Why don't there be earth-based undead creatures?

Mu Sheng saw the dark gray ground under his feet, could it be that the earth qi in the soil was absorbed by the undead creatures of the earth attribute, so he could only survive the fire attribute zombies that relied on the glory of the sun and the moon to survive?

In order to further verify his thoughts, Mu Sheng sent four elements of gold, wood, water, and earth zombies twice, and all the undead creatures he captured were all fire attributes, it seems that he was correct in his inference, and only fire-attribute undead creatures can survive in the land of death.

Mu Sheng took out the jade slip, recorded the results of the test, and began the second experiment: the symbiosis test between the land of the dead and the undead.

The purpose of the symbiosis experiment between the undead and the Land of the Dead is to find a way to break the chain of undead creatures.
