Matter moves eternally in interaction, there is no matter that does not move, and there is no motion without matter, because matter is interconnected and moves in interaction. Therefore, motion must be described in the interrelation of matter, and it is not possible to describe motion in isolation. That is, there must be a reference object for motion, and this reference object is the frame of reference.

In the same way, the life and death of all things cannot escape this iron law.

When a living creature dies, it is decomposed into two different outcomes: the corpse decays and turns into nutrients to nourish the earth, and the soul transforms into dark matter, which we often call 'ghosts'. Dark matter is so dense that it can't be directly observed, but it can interfere with the light waves or gravitational pull emitted by stars, and its existence is self-defeating. When these dark matter, for some reason, gather and do not disperse, it will form a series of unconscious 'ghosts', and those that are more evil than the spirits are called 'ghosts'.

But whether it's a 'geist' or a 'ghost', they are unconscious, and everything they do is according to their own preferences.

When they gradually have their own consciousness after countless years of existence, they become 'ghosts' or 'ghosts', which are often seen in the world, and when they want to continue their practice, they must leave the world and enter the spiritual world.

Spirituality, also known as ghost practice. Its realm can be divided into: ghosts, ghosts, ghost armor, ghost soldiers, ghost generals, ghost commanders, ghost kings, ghost emperors, and ghost saints. Their boundaries are divided according to the region. Ghost soldiers, ghost generals, and ghost commanders all have no territory of their own, but they have a certain strength, and they can find a roof to shelter from the wind and rain; and the ghost king, ghost emperor, and ghost saint are the division of forces in the spirit world.

Li Tian shouted for a long time, but he didn't see a response from the Tiger Master over there, so he thought that he was on a mission, so he didn't bother about it anymore, and turned around and walked towards the place where he was summoned.

Actually, at this time, Master Tiger really didn't have a mission. It's just that a small person like him is trying his best to protect himself a lot of times and refuses to touch anything. Just like just now, it is clear that he has good intentions, but this adult is beating and scolding, this is not something he can afford to provoke, it is better not to contact, as for what is the great chance? Forget it! It is because of this incident that he is bored in every way, and he no longer dares to pace back and forth, lest he provoke any more powerful characters.

Just as Li Tian was about to leave this gray area, he seemed to suddenly think of something, and beckoned to the increasingly dense gray substance around him, and a gray substance was suspended on his palm. Closing his eyes slightly, his consciousness seeped into the gray substance little by little, trying to parse the composition of the atoms of the gray substance.

Time passed by by every second, and in the end, Li Tian did not understand the structure of this gray matter. It's an unknown particle, with a very special structure, not an ion, not like a molecule, but it feels like an ion, and it feels like a molecule. Li Tian, who is just at the beginning of Chinese, how can he figure out something too detailed?

Li Tian didn't dwell too much on this, because the gray substance was between solid and liquid, so he had to tentatively classify it as 'plain gas'. Open your mouth and swallow this mass of 'plain qi', which is wrapped in 'too pure qi' and stored in a corner of your body.

After doing this, Li Tian sensed the call of his body and walked over slowly, while carefully feeling the changes in his body every moment. Suddenly, a strong white light shot into his eyes, and Li Tian suddenly felt in a trance. Gradually, Li Tian had a trace of consciousness, and at the same time felt the existence of his body. Slowly opening his eyes, Li Tian found himself lying on his bed.

Getting up and walking out of the bedroom, the people in the mansion saw Li Tian who had woken up, and hurriedly stepped forward to salute and ask what he needed? After Li Tian waved his hand, the people immediately sent someone to inform the sect leader Li Lan to go.

During the time that Li Lan had not yet come, Li Tian simply asked some questions, and then he realized that he had been in a coma for more than ten days. I couldn't help but worry about Li San and the others who had gone to the Polo Ghost Mountain Range? With only the hypnotism of the twelve gods, could they deal with the 'green-eyed zombie'?

Thinking of this, Li Tian couldn't help but take out the 'six coins' left by Ben Dodge to divinate the good fortune and evil of Li San and the others. When Li Tian saw the hexagram displayed by the six coins, he couldn't help but be shocked······

Bone Castle is a depression located in the southwest of Tianniu Ridge in the hinterland of the Polo Ghost Mountains. It is said to be a depression, the area of the whole city is more than 5,000 square miles, the permanent population is more than 10 million, and the garrison is 1.2 million, which is stationed in the east, west, south and north.

The cold and strange whistling sound made all the residents burrow into the bed early, and the soldiers guarding the city wall were trembling with spears and fighting coldly.

The walls of the Bone City are 20 meters high, and the surface is so smooth that no creature can climb it. However, it was the height of more than 20 meters that made the garrison soldiers unable to see everything that was happening on the ground outside the city in this dark night.

So, in a strange whistling sound, a hundred figures rushed to the foot of the city wall.

Facing the 20-meter-high city wall, a hundred figures tried many times, but they couldn't jump on the wall, and they were so anxious that they screamed. However, the cry was drowned out in an eerie whistling sound, unknown to the defenders on the city walls.

After a long time without results, these figures no longer blindly leaped, but divided into two teams, walking along the root of the city wall, one left and one right.

Soon, both teams found the gates of the West City. I've been here for so long, but I haven't even entered the city gate, these figures are naturally furious, and the first few figures slammed into the city gate angrily, but the solid city gate didn't even shake. The figures slid down the gate to the ground, their green eyes flashing in disbelief.

"Poof!" At the moment when they were confused, the figures behind them who couldn't wait jumped up and crashed into the city gate, and the city gate still didn't shake for a moment, and these figures also slid down the city gate and smashed on top of the previous figures.

Then there was another "poof!", and the figure slid down······

After being smashed for a long time, the figure below became smarter, hurriedly withdrew from below, and joined the ranks of the city gate.

Such a loud and large-scale knock on the door naturally alarmed the defenders inside the city gate. The defenders inside hurriedly sounded the emergency horn and shouted at the city wall: "Who are you?

However, how could their shouting stop the rampaging figures outside?

The sergeants behind the city gate watched as the solid city gate began to shake little by little, and then a puff of dust sprinkled down from above, and then the city gate shook even more under the impact·····

"Click, click!" One after another, the bolt of the gate finally broke, and the sand and gravel piled up behind the door were moving little by little. At this moment, a gap flashed out of the huge city gate, which was large enough for one person to pass through.

At this moment, there was an earth-shattering roar, and a figure crossed the gap into the corridor behind the city gate, followed by another figure······

At this time, the defenders who had built fortifications at the end of the aisle behind the city gate, under the light of the torches, opened the appearance of the figures who had hit the city gate: they were not as big as they were, their demeanor looked a little stiff, and their clothing was different from theirs. A pair of green eyes, perhaps is exactly why they can walk at night.

Since he has not listened to the persuasion and smashed through the city gate, there is nothing to say, and the city gate guard gave an order: "Release!"

The soldiers who had already drawn their bows with arrows loosened their fingers, and the sharp arrows were like a rain of arrows shooting towards the people who broke through the city gate and entered in strange clothes. However, the first few people, with no sharp weapons, completely ignored the arrival of the arrow rain and leaped up in the face of the arrow rain.

One after another, sharp arrows seemed to have hit the steel plate, and "crackling" fell to the ground when they touched these people. The sergeants, who were shocked by the scene in front of them, were hugged by these people who flew in one by one, biting the major artery in their necks, and felt numb all over, followed by the sound of "cooing" and sucking things, and gradually lost consciousness one by one.

The only fifty people who broke through the city gate were insignificant, which was naturally insignificant compared to the sergeants who served as blockers here. However, because of their strange behavior, it greatly exceeded the imagination of these sergeants, and they were stunned one by one. Some of them reacted quickly, some dragged their spears and turned around and ran, while others raised their spears and stabbed them with all their might.

These fifty strange people, and the other fifty who were divided into two teams with them, were none other than the 'green-eyed zombies' of a small team led by the disciples of the third generation of the Twelve Divine Demons.

In the area between the first and second walls, there was chaos. At this moment, the Bone Heavenly Zhengxi, who hurried back, also landed on the first city wall. Looking at everything that happened below with a solemn face, I couldn't help but wonder, what are these invulnerable monsters?

After a while, the ground was quiet, and the soldiers responsible for holding back the monsters, except for a few who fled to the city walls, and a large part fell in pools of blood.

When he looked at the hundred monsters that entered through the two gates of the West City, and wondered why they didn't continue to suck the remaining soldiers, he saw these monsters roaring angrily in the sky, as if they were full, one by one you look at me, I look at you, as if they greeted each other, and then they leaped through the gaps in the city gate one by one and walked away·····
