There was still an expression of disbelief on the head that had been chopped off, and it was obvious that he was only one step away from escaping.
However, at this critical moment, his head was chopped off by Chu Yunfan with a sword, killing him immediately.
A terrifying aura spread, and just the terrifying aura caused the Human Federation's army to stop.
"I never thought that one day, a weak human being would be able to fight here!"
Deep in the Ten Thousand Monsters Mountain, a figure slowly walked out, each step stepping into the void, making the sky collapse.
Only then did everyone finally see it. He was an old man with a stooped figure. His hair and beard were all white and extremely sparse. It seemed that he would die of old age in front of everyone in the next moment.
But unlike his appearance, his footsteps are extremely firm, every step is sonorous and powerful, and his voice is like a loud bell.
His body was filled with an unimaginable aura of terror, and one person was able to calm down the masters of the Human Federation who were fighting.
"Dan Realm!"
Chu Yunfan's pupils shrank slightly. This was actually a strong man at the Dan level. However, Chu Yunfan was not surprised. With the foundation of Wanyao Mountain, it was not surprising that there was a strong man at the Dan level.
.
Suddenly, Chu Yunfan suddenly remembered a record of the Human Federation. Hundreds of years ago, when the Human Federation first entered the Kunlun Realm, it was attacked by the Ten Thousand Demon Mountains and almost wiped out its entire army.
At that time, there was a demon-like being who single-handedly defeated the millions-strong army of the Human Federation in the Kunlun Realm.
At that time, there were no martial arts masters in the Human Federation at all. There were only a few innate masters, and the development of science and technology was far from what it is now.
At that time, there was almost no power to fight back.
In that situation, the Human Federation had no choice but to use a large number of nuclear bombs to kill the opponent. He alone caused hundreds of millions of casualties.
The other party seemed to be too trusting and did not take serious protection, so it was destroyed by the nuclear bomb.
And Chu Yunfan remembered that the figure recorded in that document was very similar to the old man in front of him. People will get older, but their energy and spirit will not be different.
Chu Yunfan quickly figured out that this old man was the terrifying demon god who nearly wiped out the entire human federation. Counting the time, he found that the old man was indeed in his prime hundreds of years ago.
Judging from the records of the Human Federation at that time, one person defeated an army of millions, directly and indirectly causing hundreds of millions of casualties. This is something that even Chu Yunfan today cannot do.
The possibility is that he is a master of Dan Realm.
And if there is no one else, then this should be the original master.
Looking at the intertwining of death energy and vitality in his body, Chu Yunfan immediately concluded that this was indeed that person from the beginning. At the beginning, the Human Federation thought that it would eliminate the opponent with nuclear bombs, but in fact, the opponent was not dead.
.
However, it was obvious that the original nuclear bomb did not make him feel better. In fact, even if it were a nuclear bomb hundreds of years ago, if a Dan Realm master was not prepared, he would be seriously injured or even killed.
And this Dan Realm old man was obviously severely injured, and may even have left indelible injuries. This is why the Human Federation has not seen him again for so many years. In the official archives, he is also recorded as dead.
