From the information Lu Qing has currently grasped, he can probably divide the development of the entire world into five stages.

The development period is the stage between Lu Huan's opening of the path of immortality and opening up the connection with the boundless divine realm and the bottomless abyss.

This is the stage of the ancient civilization's development from wilderness to a highly developed immortal civilization. At this stage, although the early stages were inevitable, the attacks and battles between human cultivators, demon clans, and sea clans were inevitable, and even the direct conflicts and contradictions between the main world and the satellite small world.

But overall, the entire world is peaceful and constantly developing upward at this stage.

In the early stage of the invasion of gods and demons, human monks were able to stop it at the beginning, but at the beginning, they did not regard it as an overly important threat, and even among human monks, they did not have a unified idea and regarded gods and demons as enemies.

Therefore, under this situation, human positions were lost very quickly, and a large amount of land and monks were lost, and even developed to the point where they were about to destroy the world.

It was only after suffering such a major and rapid blow that humans quickly reacted that various small worlds and forces in various fields were facing huge threats, and had to unite and fight desperately with gods and demons.

At this moment, it should be at this stage.

To the north of the Yuyan Sect, there were a lot of evil demons on the vast ice field, mainly white ghosts, supplemented by a large number of other high-level ice attribute demons.

The same army of evil demons attacked from north to south. In contrast, the main world traveled south once every decades, which was simply a pediatric department.

From the people of the Yuyan Sect, the war between the evil demons and the war was extremely fierce. For example, there was no such thing as the third-level White Ghost King in this era. The third-level unworthy of being king is simply the most ordinary cannon fodder. There are so many fourth-level white ghosts, and there are even a large number of eighth-level evil demons. This kind of thing can only be easily eliminated unless the immortals come out, otherwise the powerful Dongxu will only be able to come out.

For example, when their Yuyan Sect responded to the call, they gathered elite sects and went north to participate in the war. After the battle, only six elders came back. The Supreme Elder who reached the Shenhai Period was killed in battle, and all the Dharma images of the entire sect were killed in battle.

But after paying such a great price, the front line will only be able to maintain it.

But a large number of evil demons still emerged from the extreme Arctic ice fields and then went south.

Even those who are optimistic about their mentality do not think that the front line can withstand it for too long.

I think this early stage is the collapse stage.

And further ahead, Lu Huan should sacrifice himself to create a world lock, and block the connection between the boundless divine realm and the bottomless abyss and the main world. With this as a landmark event, the third stage will be kicked off.

At this point, the number of gods and demons no longer increased. However, since during the collapse stage, there were already a large number of gods and demons coming to the main world, and a large number of local creatures were corrupted or surrendered, this was still a very difficult period.

And gods and demons should not be willing to fail. On the one hand, the number and average strength they still have in the main world are very strong. On the other hand, they must be trying to break the world lock created by Lu Huan and try to open the channel again.

During this period, many immortals formed an immortal association to rule over all races, gather strength to fight against gods and demons, eliminate gods and demons, and protect the world locks.

In the end, at this stage, the main force of gods and demons was destroyed, and the immortals almost died with these gods and demons.

In the fourth stage, Lu Qing called it the "Stage of Nirvana". Although the main world was a tragic victory in the end, the achievements of civilization were almost destroyed, and a large number of monks died, so that even civilization could not survive. At the same time, due to the existence of the world lock, the power level of the entire world gradually declined, and the ancient civilization that was almost destroyed also lost the soil for growth and recovery, and completely destroyed it.

And this stage of nirvana, in theory, has continued to this day.

Although, now, the civilization of the whole world has actually developed again, no matter what the more glorious and unified Great Zhou Dynasty and the current nine immortal kingdoms are, compared with the ancient civilizations, they are extremely simple and cannot reach that level at all.

The world lock has a great influence.

At present, what Lu Qing has to face is the node when the fourth stage is approaching and the fifth stage is the node when the gods and demons invade again.

It’s hard to say what the future will look like, but there are only two endings:

When the gods and demons officially invade, and the main world is far from ready, the whole world is completely integrated into the boundless god world or the bottomless abyss. If this is the result, there is no need to name it, and you will be done if you die.

The second ending, through time backup, cut off cause and effect, so that the channels of the abyss or divine realm are gradually closed. They successfully postponed the invasion of gods and demons for thousands of years, or even ten thousand years later. At that time, the source of the world lock will not continue to block the upper limit of the power of the entire world. After such a long period of development, a large part of the ancient situation will be able to restore.

At the same time, after thousands or ten thousand years of preparation for the invasion of gods and demons, the entire world will surely be more prepared than the ancient civilization that was suddenly invaded. It can even turn the enemy into the enemy first, find the invasion of gods and demons, and directly bombard them back before they invade, and then find a way to close these channels to ensure the safety of the entire world.

And even, while closing the channel, keep the entire world away from the divine realm and the demon realm, avoiding being invaded again...

"Anyway... I still have to make a copy." Lu Qing sighed.

"Senior, do you think of a copy? What copy?" The young Bai Jianxian next to him, Yan Luo, couldn't help but ask when he heard what Lu Qing said.

In recent days, Lu Qing has spent most of his time chatting with Yan Luo and guiding him in his swordsmanship.

Some things in the Taibai Sword Book, just a little bit, were enough for Yan Luo to benefit for a long time. The most important thing was that Yan Luo found that there were many aspects of the two people's ideas that coincided, but Lu Qing went further than himself and thought much more maturely.

In addition, when Lu Qing communicated with him, he had almost no airs. Even though the two had only been in contact for five days, Yan Luo had already attracted Lu Qing as his confidant and was the guide on his own path of cultivation. He was more respected by him than his own master.

This feeling made Lu Qing feel very secretly happy.

I will teach you what you taught me, and you have to thank me!

This also made Lu Qing feel a lot of fun in the last few days of the time fragments.

Seeing that the fragments of time had entered the countdown to the end, Lu Qing smiled and said, "The world depends on you to save. In addition, I also need to thank you for your remuneration for your success."

"Senior? Senior, do you call me Senior?"

The face of Bai Jianxian Yan Luo was full of doubts.

This puzzled expression suddenly solidified in front of Lu Qing, and then gradually dissolved and eventually turned into a bubble.
