At his peak, the imperial dragon energy was so strong that he could suppress the entire world, and no one could be his opponent.

When he was alive, no one dared to offend that person.

Even though the King of Western Chu was already approaching adulthood and his lifetime strength was close to that of a Martial Saint, with such terrifying talent and talent, coupled with his physique, he still did not dare to say much in front of the First Emperor and even had to retreat on his own initiative.

When the First Emperor was alive, no one dared to touch his brow.

He is alive and truly the best in the world.

When such a person died suddenly, many statements did not match, and there were all kinds of speculations.

Some people say that he was injured by an assassin sent by Yan, one of the six kingdoms, when he unified the world in his early years.

Some people also say that this person was injured by the mysterious witchcraft of the barbarians when he was sweeping the northern barbarians.

No one has been able to explain it clearly till now, and it can only become a historical mystery.

And the man who now sits on the throne, the one who calls himself the Lord of the Underworld, seems to have his own answer to this historical mystery.

"For you, this may be filled with endless doubts, but for the most secret files of the Kyoto Imperial Family, this matter is not unsolvable."

Zhang Mingtu lowered his eyes and looked at the shadow of Kyoto appearing in the underworld, and chuckled softly.

"What?"

Qi Guangji was shocked for a moment and couldn't understand why there was such information in Kyoto, but they were still unwilling to make it public after eight hundred years. After all, this incident happened too long ago, and even dynasties had changed several times.

At this point, there is no need to hide the truth for the sake of the venerable, so why is it not made public? He vaguely feels that there is a huge secret hidden in it.

"If it's been so long, and they still know the secret, why haven't they revealed it?"

Zhang Mingtu looked at the pairs of eager eyes below and chuckled, "Because this involves immortality and a higher world."

"What?"

It was as if thunder was flashing and vibrating between heaven and earth. Qi Guangji's expression changed, and Yu Zhifu was no longer as calm as before.

Even Yang You, who was always in a daze, was a little curious.

Immortality has always been pursued by emperors of all dynasties, and each generation of emperors has made countless explorations into immortality.

Even the first emperor, the First Emperor, had a strong desire for immortality.

He sent people out to sea three times, outside the ocean, trying to find the legendary fairy island and the elixir of immortality. He also searched for countless ways to refine the elixir of immortality on earth.

It wasn't just his later military and literary prowess, even surpassing his predecessors in completely defeating the Northern Barbarians. Emperor Wu also had a strong pursuit in this area, constantly searching for the elixir of immortality in his later years...

Throughout the ages, emperors and generals seem to have been pursuing something in this regard.

When the word "immortality" is mentioned, everyone present will be shocked.

"Did he die because he accidentally took an elixir in pursuit of immortality, damaging his essence?"

Yu Zhifu frowned. This speculation also occupied a lot of space among historians, and many people supported this statement. Because according to the daily records, the First Emperor did like to take elixirs and would take various refined elixirs all year round.

If the poison is not removed after taking various kinds of elixirs in the early stage, it may cause great hidden dangers in the body and lead to premature death.

Even today, there are still top masters who suffer hidden dangers from swallowing indigestible pills.

But this statement can convince others, but it cannot convince Yu Fuzhi that Yu Fuzhi is a natural dragon body.

He knew very well the special effects of the True Dragon Body. The True Dragon Body not only had strong vitality, but also had a strong ability to detoxify various poisons.

What’s more important is that people with the body of a true dragon are also very good at distinguishing various medicines.

It is difficult to be poisoned to death, unless it is suicide.

"Oh!"

Zhang Mingtu chuckled lightly, the contempt in his words was not concealed.

"This world doesn't have the elixir of immortality that can poison a Martial Saint, but pursuing immortality and swallowing the energy of heaven and earth, unable to withstand it, and dying from it is very reasonable."

"What did you say?"

Yu Zhifu couldn't quite understand.

Zhang Mingtu calmly said, "In a small pond, raising a fish weighing over ten kilograms is already the limit. If a big fish wants to achieve immortality, to live a long life, and to possess the boundless power of a giant shark in the deep sea, there is only one way... it needs an ocean."

Zhang Mingtu's words were calm, but they sounded like thunder to Yu Zhifu and Qi Guangji.

Yu Zhifu recalled that period of history and asked in surprise, "Are you saying that the First Emperor of Daxia ascended to heaven and truly became an immortal?"

This news shocked him, making him feel hard to believe, but also made him feel quite reasonable. A Martial Saint who was about fifty years old and still possessed the body of a true dragon was only at the beginning of his life on the path of cultivation, and was very different from ordinary mortals.

It is unbelievable to die at this stage, but if you survive and break through the void and ascend to a higher world, then it is acceptable.

Perhaps the First Emperor did not die suddenly, but suddenly shattered the void with force, which left behind a lot of problems and almost caused the collapse of the Great Xia at that time.

Qi Guangji also looked shocked, as if he had learned some ancient secret.
