Calamity

Lu Yuan had been curious before. In the history of the Upper Realm, there had been many Beast of Antiquity.

It was rumored that the strength of these Beast of Antiquity was not weaker than that of immortals.

But now, all these Beast had disappeared without a trace.

Only a small portion of the Beast of Antiquity still existed.

However, even this portion of the Beast of Antiquity had lost the unparalleled power of their ancestors.

What surprised Lu Yuan even more was that these Beast of Antiquity seemed to have disappeared overnight.

In the Speed Star Sword Domain library, Lu Yuan tried to investigate this missing part of history.

However, the results of the investigation disappointed him.

Whether it was the Beast of Antiquity or the legendary immortals.

In the ancient books of the Upper Realm, it seemed to have only become a legend. Very few specific records were passed down.
