Under Yan's reminder, the Yan clan and the human race began to consciously make various preparations to cope with the weather changes in the four seasons.
What followed was that the art of drilling wood to make fire truly spread throughout the human race.
The human race has now completely bid farewell to the era of caring for hair and drinking blood, and has begun to take the first step of relying on acquired efforts to change and fight against the power of heaven and earth.
By this time, Yan's name was also spread by ordinary people along with the spread of drilling wood to make fire, and began to resound throughout the entire human race.
At the same time, because of the spread of the art of weaving linen and making clothes, Yu's influence among the human race is growing.
Even no less than Yu Hesong who preached the truth in the ancestral temple.
Because of this, Yu's human luck has grown rapidly in recent years, and he has benefited a lot.
However, although the human race is constantly making various preparations.
But in fact, for ordinary people, with their life span of one or two months, it is impossible to wait for the evolution of the four seasons and celestial phenomena.
Because although the four seasons and celestial phenomena are promoted by the control of the Wu clan, their evolution speed is constantly accelerating.
But if we really want to completely complete evolution, this cycle must be calculated in units of at least hundreds of years.
But even so, neither Yan nor the high-level immortals of the human race in the Renzu Temple changed their decision.
After all, no one can be sure that there will be no variables in the evolution of celestial phenomena in the four seasons.
The human race is naturally weak and has extremely low risk resistance. Only by making more preparations can we better resist risks.
Moreover, preparing early may result in a lot of useless work, but it can allow certain habits to become instinctive over time, allowing you to adapt to dangers and changes faster.
In this way, under the constant attention of Yan and the immortals of the human race, hundreds of years passed slowly.
The human race also gradually learned to use fire, began to dig caves to live in, weave linen clothes to keep warm, and also developed the habit of collecting and storing food and furs.
At this time, the changes brought about by the evolution of the four seasons and celestial phenomena between heaven and earth finally slowly began to appear.
The order of yin and yang and the five elements between heaven and earth gradually changed and began to become more active.
The world's climate, which had always been relatively stable, is no longer static and has begun to fluctuate.
The life and death scheme between heaven and earth also became chaotic and unpredictable.
On Ziyanling Mountain, Yan was currently playing chess with someone.
Opposite him, Ziyan Lingjun looked at the chessboard casually, but his thoughts were obviously not there.
"Fellow Taoist, there have been some changes in the secret realm of the underworld recently, and I'm a little undecided."
Yan frowned and stared at the chessboard with all his concentration. Seeing that he was about to lose this game again, he held the chess pieces unsteadily with a slightly embarrassed look in his eyes.
After all, no matter who it is, if they keep losing chess one after another, they will not be in a good mood.
What's more, the loser is actually his own clone, which is even more embarrassing.
Now hearing the words of Ziyan Lingjun, Yan couldn't help but breathed a sigh of relief, and his hanging arm fell down, disrupting the chess game.
Then, as if nothing had happened, he frowned and asked:
"We control the origin of the secret realm of the underworld, and countless ghosts and gods have descended here over the past few hundred years.
The Tao Yun is infecting and nourishing, and the incense of luck is constantly tempering. Are there any changes that can make you undecided? "
Ziyan Lingjun glanced at the disrupted chess game, narrowed his eyes slightly, and looked up at Yan who was as if nothing had happened.
He couldn't help but shook his head, reluctantly dropped the chess piece in his hand, and his mind began to turn to business.
Thinking of the recent inexplicable changes in the secret realm of the underworld, I couldn't help but frown slightly.
“I actually don’t know what the specific changes are.
I just vaguely felt that something had changed in the world, and there was a faint feeling of frightening uneasiness. "
Hearing what Ziyan Lingjun said, Yancai really paid attention to it. He frowned and looked up into the other person's eyes to confirm that he was not talking nonsense.
"You don't know either?"
You know, although this secret realm of the underworld was opened by Yan with the pen of the judge of reincarnation.
But since the birth of Purple Flame Spirit Lord, he has always been in control.
Hundreds of years have passed, and Ziyan Lingjun has relied on the endless incense and wish power, as well as the continuous flow of merit and luck, to achieve a level of cultivation that is no less than that of Yan.
Even, through the authority of Shinto, integrating the power of ghosts and gods, to a certain extent, the strength has even surpassed the original body.
Such strength, and being in the secret realm of the underworld in his base camp, can actually make him feel uneasy, but he is not aware of it.
Yan couldn't help but feel extremely frightened, his mind was spinning, and he couldn't help but feel a little suspicious.
"I just have this faint feeling!" Purple Flame Spirit Lord nodded cautiously.
"Where are the other gods? Have they noticed any changes?" Yan continued to ask.
Purple Flame Spirit Lord shook his head when he heard this and said: "No!
But Pan Yu seemed to feel it too. "
Yan narrowed his eyes slightly when he heard the words. Pan Yu could be said to be the first Yin ghost in the secret realm of the underworld. If Yan had not intervened, he might be the destined person between the secret realm and the innate spiritual treasure.
Now, although he has long lost that fate, his merits in presiding over the trials of ghosts in the secret realm over the years are not small.
Coupled with the original luck and fate, it is not surprising that I feel something.
However, since then, it is almost certain that something may really go wrong in the secret realm of the underworld.
"What are you thinking? Is it the natural change of heaven and earth, or is there some other reason?"
Yan asked with a somewhat inexplicable expression, and a certain worry in his tone was unmistakable.
As a clone of Yan Shendao, Ziyan Lingjun naturally understands Yan's worries.
Fuxi of the demon clan opened up the underworld, and Hou Tuzu Wu of the witch clan was the pioneer of reincarnation.
Both have the power to quietly and unknowingly influence Yan's underworld secret realm.
“I think the natural changes of heaven and earth may be even greater!
After all, compared to the entire prehistoric underworld, our secret realm of the underworld can be said to be insignificant.
Moreover, there are vast divine bridges connecting them. If you really have the will, you can change the world with just one thought, so there is no need to go to such trouble. "
Yan Wenyan also agreed with this statement in his heart, couldn't help but nodded, and felt much calmer.
My mind was calm, my thoughts naturally became clear, and I had an idea in my mind, and I guessed thoughtfully:
“Over the years, the weather in the four seasons between heaven and earth has evolved, and the sequence of yin and yang and the five elements has fluctuated like tides.
Perhaps, this change in the secret realm of the underworld comes from this. "
Hearing this, Ziyan Lingjun's eyes narrowed slightly. After thinking for a while, he nodded and said:
"It's possible!"
Although Ziyan Lingjun agreed with Yan's guess, Yan himself actually had no idea, so he said:
"In this case, I can't explain why here.
Let's go to the secret realm together and take another look. Maybe there will be other discoveries, but I don't know for sure. "
Saying that, the two of them did not hesitate and went directly to the secret realm with a thought.
After entering the secret realm, the two of them quietly looked around without alerting the gods.
The result was not surprising, still nothing was found.
At the same time, Yan also slowly felt faintly depressed and uneasy from the secret realm.
Seeing this, Yan Xin thought about it, and his mind merged with the Purple Flame Spirit Lord, and his consciousness was infinitely condensed and lifted up.
Then, he borrowed the innate spiritual treasure - the Samsara Judge's Pen as a medium.
The vertical eyes between the brows suddenly opened, purple light flickered, and the entire secret realm of the underworld, the cause and effect, luck, and fate, flashed through the eyes one by one, and every detail was visible.
