All realms have enabled me to achieve the Great Dao.

Zhou Yongcheng then thought of the existence of the Yun Dynasty in this world. Could that city wall be the boundary of the Great Xia Heavenly Court? It was possible, and it might even be a magical artifact that could defend against enemies.

Turning his gaze away, Zhou Yongcheng walked forward. Not far ahead, he came to a commercial street where many people were selling things.

Zhou Yongcheng walked up to a stall with many bones and demon cores on it.

The bones and demon cores were covered with many mysterious patterns. Zhou Yongcheng scanned them with his divine sense and found that some bones contained abundant energy that could be absorbed for cultivation, as could the demon cores.

"These were taken from some kind of monster."

"Reporting to senior, this one is a dragon bone, taken from a black dragon at the Demon Emperor realm, and this one is from a wind wolf at the Demon Emperor realm..." The stall owner introduced the items on his stall to Zhou Yongcheng.

Zhou Yongcheng glanced at the stall owner, who was an immortal at the Immortal Emperor realm, and a late-stage one at that, with quite impressive cultivation.

After listening to the stall owner's introduction, Zhou Yongcheng bought several bones and several demon cores from the Demon Emperor realm.

The stall owner was quite shocked to receive the innate spirit stone from Zhou Yongcheng. This thing was no ordinary item; only top-tier forces possessed it.

After buying the goods, Zhou Yongcheng inquired about the situation of Guixu City from the stall owner.

The stall owner said that the great battle with the demon race had just ended yesterday, and both the human and demon races suffered heavy casualties. These things were obtained by them from hunting demons.

Zhou Yongcheng learned that hunting demons at the border was not just a matter for the Great Xia Heavenly Court; any human, regardless of their faction, would come to the border to hunt demons.

Many humans also make a living by hunting monsters. There are many things on monsters that can be used. Some things can be used to refine weapons, some things can be used for cultivation, and if you don't use them yourself, you can sell them. It's a win-win situation.

In particular, some forces have their own lineages in the lower realms, and their disciples ascend from time to time. These newly ascended disciples need to be nurtured with resources, and hunting demons is a good way to do so.

In the original continent, cultivation resources are basically controlled by major powers. Some powers without Dao Lords or Dao Ancestors can only be considered small powers. Small powers and rogue cultivators can only obtain cultivation resources by hunting demons and monsters.

"Have the human race's powerful members ever thought of killing off the demon race's powerful members? If they could take over their territory, their resources would be abundant."

"Senior, there has been an agreement on the Origin Continent since ancient times that those who have reached the Dao Lord realm cannot interfere in the wars between the races. Millions of epochs ago, a demon ancestor broke the agreement and attacked a holy land. As soon as he made his move, a Heavenly Eye appeared in the endless void and sent down heavenly punishment, which destroyed that demon ancestor. To this day, no ancestor above the Dao Lord realm has dared to make a move."

Zhou Yongcheng had not expected that such an agreement existed in this world. It was possible that it was a constraint imposed by the Heavenly Dao on cultivators above the Dao Lord realm. If it were not constrained, and all cultivators above the Dao Lord realm on the Origin Continent were to take action, the Origin Continent would probably be torn apart, which would be detrimental to the world and to the Heavenly Dao.

When will the demon race launch another attack?

"The time is not fixed. If you want to hunt demons, you can go out of the city."

Zhou Yongcheng left the stall and wandered around for a while before arriving at the city wall. Several city gates were wide open, and each gate was guarded by someone. Judging from their cultivation levels, none of them were below the Taiyi Realm, which is the Immortal Emperor Realm.

People were leaving and entering the city gates, but the guards didn't pay them any attention or charge them any fees. It seems that the Great Heavenly Court is still quite capable; those who went out to hunt monsters didn't have to pay any fees upon their return.

Zhou Yongcheng also left the city with some others.

The difference between the outside and inside of the city is significant. The air outside the city contains a stronger sense of malevolence, perhaps because the outer city was a battlefield.

Although the area outside the city was a battlefield, the ground outside was quite clean, and no corpses were seen.

Zhou Yongcheng asked a person who had left the city with him.

"Didn't they say that the great battle with the demons outside the city just ended yesterday? Why isn't there a single demon corpse outside the city?"

The man initially disdained to answer Zhou Yongcheng's question, but he failed to realize Zhou Yongcheng's level of understanding, implying that this man's level was certainly higher than his.

"Senior, the walls of the Great Heavenly Court have the ability to absorb the corpses of demons. All the demon corpses after the great battle are thrown into the walls. I heard that the walls of the Great Heavenly Court were originally called the Great Wall. The more demons they absorb, the more powerful the walls become."

Upon hearing this, Zhou Yongcheng realized that the Heavenly Emperor of the Great Xia Dynasty was undoubtedly a time traveler, possibly even from a modern world.

"Thanks for clearing up the confusion."

"Senior, you're welcome."

Seeing that Zhou Yongcheng had no problem, the man turned around and disappeared from the spot. Once outside the city, there were no restrictions, unlike inside the city where there were so many restrictions.

Zhou Yongcheng scanned the surroundings with his divine sense. This area outside the city had long been a low-lying area due to the great battle between the human and demon races. Over the years, this area had been attacked by powerful beings using supernatural powers and spells, and it was already in a terrible state.

The low-lying area stretches for hundreds of millions of kilometers from Guixu City before the city of demons comes into view.

Zhou Yongcheng disappeared from his original spot and appeared in the void hundreds of millions of kilometers away.

There are demon cities here, as well as endless forests.

In the void, Zhou Yongcheng could sense that there were powerful demons guarding the city, at least at the level of a Celestial Venerable in this world.

Since the Dao Lord cannot participate, only the Immortal Venerable is the strongest fighting force.

Zhou Yongcheng was thinking that since the Dao Lord could not take action on the Origin Continent, what could be done outside the Origin Continent, such as in the chaos of the endless void, or in a higher-level world above the Origin Continent?

He shook his head, realizing that his current level was not high enough to observe how experts at the Dao Lord realm played chess. He then looked down at the demon city below.

The demons active in the demon city mostly transform into humans, but they retain some characteristics and do not completely transform into humans.

For example, horned demons will display their horns to indicate their specific race.

Zhou Yongcheng saw that in the demon city, many demons had a pair of horns on their heads, including dragons, cows, and sheep. Some of them, without obvious features, would change their heads to resemble humans, thus becoming half-human and half-demon.

After observing for a while, Zhou Yongcheng disappeared into the endless void and arrived in the endless forest beside him.

There are some human mercenaries active here, hunting down lone demons.

Zhou Yongcheng didn't hunt down the demons; he was mainly just watching the show.

After teleporting to several places, Zhou Yongcheng had no idea where he had arrived. He saw a group of monkeys.

Among the monkey tribe, there is a demon lord leader and several demon emperors.

They did not transform into human form, but lived leisurely in the endless forest in their original form. These creatures may not have participated in the racial war, and Zhou Yongcheng did not see any seeds of hatred in them.

Although they did not participate in the racial war, Zhou Yongcheng coveted their possessions.

Under the scan of his divine sense, Zhou Yongcheng discovered the celestial wine in a mountain cave.

Zhou Yongcheng also saw some monkey demons bringing fruit, medicinal herbs, and other things into the cave.
