One hundred and forty-two years ago, Tengyun returned to the Central Plains from the country of Youyi.

As soon as he returned, he entered the palace to face the saint and had a secret conversation with the emperor for several hours.

The Holy Son of the Great Zhou was very interested when he heard that there was a country of longevity overseas, and in order to make himself live as long as the people of the Yi Kingdom, he immediately ordered the Teng Snake Hall to be separated from the Dark Moon Division, making it a special institution that directly obeyed the emperor's orders.

This top-secret decree allows Tengyun to concentrate on studying the secret of the longevity of the people of Yi without the interference of external factors.

Tengyun was ordered to move the entire Teng Snake Hall to Youyi Kingdom, and all the personnel accompanying the ship stayed in Youyi Country to prevent secrets from leaking out.

Since then, Teng Snake Hall has been erased from the official records of the Great Zhou Dynasty, and matters related to it have become top secrets.

Descendants who don't know this history naturally haven't heard of Tengsnake Hall, and they all think that there are only five halls under the Dark Moon Division.

Tengyun, who arrived in Youyi Kingdom, would send someone back a secret letter from time to time every year to report the results of the research to the emperor.

A few years later, Tengyun's research progressed.

In the secret twist, Tengyun told the emperor that the secret of the longevity of the Yi people had something to do with the island they lived on.

After landing on the island, the ancestors of Youyi found that the land here is fertile and rich in minerals, which is very suitable for human settlement, so they decided to take root here and not continue to wander.

After a while, something terrifying happened.

Everyone found that their bodies had mutated and became less like people and ghosts than ghosts.

Even babies born on the island are no different from ordinary babies at first, and when they grow up, they become half-human, half-beast.

At this moment, the inhabitants of the island fell into a panic.

Some saw it as an ominous and cursed place, and families left by boat in search of a new settlement.

Those who stayed behind slowly found themselves living longer, and dying in their 100s was considered short-lived.

Other than that, there was no other discomfort.

As a result, the Youyi people living on the island gradually accepted this result and multiplied to this day.

This anomaly made Tengyun realize that only the inhabitants of the island could live a long life.

Correspondingly, these outsiders, who have lived on the island for several years, feel that they have become younger and full of vitality.

In other words, no matter who leaves the country, their life expectancy will also be shortened, and they will eventually be no different from ordinary people.

This fully shows that there is a mysterious factor in the island that makes people live longer, but the side effects are very obvious.

Even Tengyun himself could feel the visible changes in his body.

I'm afraid that if he stays for a few more years, his appearance will be no different from that of the inhabitants of the island.

After seeing Tengyun's secret fold, Da Zhou Tianzi was very annoyed.

If the true dragon son with noble bloodline becomes a monster, it will be too detrimental to the majesty of the royal family.

Just when the Emperor decided to interrupt his research and prepare to recruit all the staff of Teng Snake Hall, another secret letter sent by Teng Yun made him change his mind.

In that secret fold, Tengyun reported to the emperor that the reason for the longevity of the Yi people was due to a mysterious building on the island.

This mysterious building is called the Temple of Creation by the people of Youyi.

According to the legend of the Kingdom of Ariyi, the temple existed before their ancestors arrived on the island.

No one knows when it was built, and no one knows where the builder is sacred.

As for the purpose of building this temple, no one knows.

When the ancestors set foot on the island, they saw the temple standing alone in the middle of the island.

People who entered the temple found a tall statue of the god standing in the center of the temple.

Holding a giant axe, the statue of the god stands proudly, resembling the legendary Pangu ancestor who opened the world.

The ancestors were extremely shocked, and they all thought that the ancient ancestor of the Creation God Plate was protecting everyone from coming here, so they called it the Creation God Temple, and set up a special position of high priest to worship from generation to generation, and did not dare to slack off in the slightest.

Some Yi people regard this building as a temple, but Tengyun is keenly aware of its peculiarities.

As an immortal cultivator, he sensed that the entire temple was filled with tremendous energy.

This is a very magical energy, which can actually have a mysterious resonance with the true qi in the body.

Tengyun had a good relationship with the high priest, and after getting permission, he moved into the temple.

Subsequently, he found that his cultivation in the temple had the effect of getting twice the result with half the effort.

In just one year, Tengyun's cultivation broke through the Seven Rounds Realm, stepped into the Three Veins Realm, and became a powerful cultivation master.

It was only then that Tengyun understood what was going on.

The reason why people with Yi Guo live long is because of this energy!

Since they were ordinary people who didn't understand the art of cultivation, long-term exposure to the energy emitted by the temple could only allow them to live a long life, but they couldn't have the same powerful strength as immortal cultivators.

Everything seems to have a satisfactory answer, but there is still a mystery that cannot be solved.

That's why does this mysterious energy mutate people's bodies?

Unable to explain this phenomenon, Tengyun begged the emperor to stay on the island and conduct research.

Hearing this, Chu Fan looked shocked and unbelievable.

A physical word that only modern society came to his mind: nuclear radiation!

Only nuclear radiation can mutate people, and that temple is actually an enclosed building used to prevent nuclear leakage!

Or maybe there are radioactive materials in the temple, but the people of Youyi who don't know the inside story open it to the outside world as a temple!

"This ...... How can it be? ”

Chu Fan exclaimed in his heart, and it was difficult to accept this judgment for a while.

In this ancient overhead world, things from modern civilization have appeared one after another, which is incredible!

Seeing Chu Fan's unyielding appearance, Murong Xue stopped speaking and asked, "Little brother, is this strange thing I said beyond your comprehension?" ”

"No, no."

Chu Fan hurriedly shook his head, for fear that Murong Xue would find out his identity as a traverser.

Zhong Lifei, like his apprentice, frowned as he listened.

It's just that he said with great interest: "Brother Xian, look at what you said, I can't wait to go to Yiguo to see what is going on." ”

Murong Xue persuaded: "Don't be anxious, brother, it's too late for you to move after you get well." ”

"Brother Xian, don't you think it's strange?"

Zhong Lifei groaned and said, "Isn't it a contradiction that it is obviously a blessed land for cultivation, but it makes people look weird? ”

Murong Xue smiled silently.

Zhong Lifei continued: "If you follow the right path for cultivating immortals, you will not let yourself become a monster. Only those who go mad can transform into demons! ”

After listening to Master's words, Chu Fan suddenly realized that he had misjudged just now.

The energy in the temple will never be nuclear radiation.

Nuclear radiation can make people sick and even mutate future generations, but it will never make people have the genes to live a long life!

Otherwise, as Master said, it is purely a contradiction.

Chu Fan couldn't help but be curious about this mysterious energy.
