The vast renovation project of the new Thousand Bones City has been in full swing for more than a month, and in addition to the city lord Theo, all the members of the Thousand Bones City participated. As the commander-in-chief, Yuna counted Canaan into account, and in her words, Canaan was so tall that he didn't work for nothing.

Theo has been idle these days, just walking around the city, as if he is investigating something, quite carefully. His mind kept thinking about some of the things he had discussed with everyone the other day.

That day, Rin Dong was reporting to him the current strength of the city after the war. There are two skeleton generals in total, equivalent to one skeleton general's king corpse, seven skeleton knights, because some ordinary skeletons advanced, and later the skeleton soldiers have reached 4,000, but ordinary skeletons have suffered heavy losses, the two cities had more than 200,000 skeletons before the war, and less than 30,000 remained after the war.

Theo asked him on the spot why he didn't replenish his troops, were there no skeletons scattered in the wilderness?

Winter explained that since the disappearance of the River Styx and the disappearance of the order of the cycle of life and death, the four skeleton plains in the Skull Domain have no longer given birth to new skeletons, and the current number has been carried over from 100,000 years ago, and has been sharply reduced to less than one in 10,000 under the condition of fighting and annexing each other over the years.

The number of wandering skeletons in the wilderness is very rare, and there are basically some powerful ones who come out to wander and travel through the skeleton domain, and there is no shortage of skeleton generals or even skeleton marshal level. But more groups are not these, but spies scattered outside in various realms and cities to inquire about news and monitor movements. It's just that this kind of spy identity is very funny, and it is usually difficult to come back after going out, either being killed, or being completely absorbed by other high-level skeletons.

Therefore, it is extremely undesirable to replenish troops from the wilderness. The pattern of the Skull Domain has been formed for a long time, and the skeletons prefer to gather in the protected city, after all, this is the safest way to survive.

But even so, in these cities in the Skull Domain now, there are millions of skeletons, large and small, and there are only tens of thousands of them. It depends on the strength of the city lord to determine whether more skeletons are willing to serve him.

To know. 100,000 years ago, every skeleton city was inhabited by tens of millions or even hundreds of millions of skeletons, these skeletons crawled deep into the earth through the crypt, once awakened wisdom or heard the call of battle, they would emerge from the crypt layer by layer, the skeletons living on the ground have a certain wisdom or have the ability to speak, and those who are not civilized, driven by instinct, will move or sleep deep under the ground.

It is said that 100,000 years ago, the lord of every skeleton city was at least a skeleton lord or above. Like later, as long as he was a skeleton general, he could occupy a city.

The way to advance in the Skull Domain 100,000 years ago was not just by devouring its own kind, each Skull City had a soul array, which was said to have been formed by some residual water of the River Styx when it flowed through the depths of the earth.

Every once in a while, the Soul Circle will erupt with some soul fires of different qualities, and the skeleton people can accept the gift of the great River Styx, and countless lucky ones will get the chance to advance.

Of course, the high-grade soul fire will be taken away by the city lord and devoured by himself or distributed to his subordinates, while the low-grade ones will still be fought over by the skeletons in the city. Therefore, the day of the eruption of the soul array is both the carnival day of Skull City and the day of disaster, according to the understanding at different levels.

Because of the unique way of generating life in the Skull Domain, from ancient times, it has always been the main force in the underworld wars or expeditions, whether it is evaluated in terms of combat effectiveness or deterrence.

And the shadow that envelops the entire Skull Domain is that there are no new skeletons in the Skull Domain, killing a batch of fewer batches, if the endless killing continues, the skeletons of the Skull Domain will also die, and if they want to advance to a higher level, they must only continue to kill and devour.

Strictly speaking, this is the shadow that envelops the entire Netherworld, but the contrast of the Skull Domain is the largest, and the consumption is more prominent.

Theo also asked Rin Dong where the specific location of the soul array in Thousand Bones City was, but Rin Dong didn't know, and even Canaan, who had read the memory of a Thousand Bone, didn't know. It took them all nearly a thousand years to give birth to wisdom from ordinary skeletons, and they have advanced step by step to today.

In the past 100,000 years, those who can remember where the soul array is are estimated to have been devoured year by year or gone farther away.

Theo has also been looking for traces of the disappeared soul array these days, to see if he can awaken the soul array through the power of the reincarnation book. In a month, he circled the entire Thousand Bone City more than a dozen times, but still found nothing.

On this day, when he walked to a mound in the south of the city, he suddenly felt a trace of energy coming out of it, and the fluctuation was very small, if it weren't for the reincarnation book in his hand and used it like a compass, he wouldn't have noticed it.

He stood on the mound for a half-moment, feeling it carefully, and there was a familiar aura in the energy, yes, the remnants of the River Styx.

A patrol of skeletons was walking a short distance behind him, and Theo beckoned to them:

"Over there, you all come here. ”

The group of skeletons saluted Theo from afar, and quickly ran over.

"Dig this mound and dig it all the way down. ”

The skeleton soldiers immediately surrounded them, picking them with bone knives and digging with bone hands, and piles of black soil were scraped aside, mixed with many rotten bones that had gone through an unknown number of years.

After a long time, a cave with a diameter of five or six meters and a depth of about ten meters was formed, and a black pattern resembling a burning one appeared underground.

"Stop! ”

Dozens of skeletons climbed up one after another along the walls of the reclamation depression, and when they were digging, they had been digging down layer by layer at a slight inclination, so that the cave was very deep, and they still climbed out easily.

Theo jumped down, walked around the pattern, looked at it carefully, bent down, and touched it lightly with his fingers.

There was a faint glimmer of light in the black pattern, and if he hadn't been attentive, Theo might not have noticed.

Theo summoned the reincarnation book, dipped his finger in spit, and quickly flipped through the page.

"I see, the soul array did not collapse, but it just lost the source of its origin. If you use the reincarnation book as a substitute, there should be a chance to reawaken. ”

Theo decisively tore a page from the book of reincarnation, and after the paper broke away from his palm, it turned into a cluster of milky white light and fell into the center of the black pattern.

"Across the endless years, the shattered shadow of the River Styx, I use the voice of the soul, with reincarnation as a carrier, calling for your response, awaken again!"

The black ashes on the pattern seemed to go back in time, slowly becoming full from a piece of dead air, and the dark green light swirled, soaring into the sky, alarming the busy skeletons of the entire Thousand Bones City. Several powerful figures galloped towards the south of the city.

"Haha, it really works, this king will add some more ingredients to you as a reward. ”

Theo cut through his palm with his fingernails, and a drop of dark red blood fell on the eye of the soul array with a dingdong sound, seeping in instantly and disappearing.

The thick green light of the soul array became more and more intense, and among them, a black and white entwined light could be faintly seen, like a small snake swimming in the green ocean.

In later generations, every time the soul array of Thousand Bones City erupted with soul fire, at least several skeleton lords were directly born, many of which were even directly born as golden skeletons, and the more outrageous legend is that there was a low-level skeleton that had not yet been civilized and wise, and was lucky to be hit by a cluster of black and white weird soul fire, and jumped from the lowest skeleton to the skeleton king, and unified the entire Eastern Regions of the skeleton domain. The reason why the soul array of Thousand Bones City is so legendary is said to be because at the eye of the array, there is the body of the reincarnation book sitting in the seat, and there is even a drop of the blood of the Hades sleeping there.
