Yi Yun did not know about the strongest figures in the Tian Yuan world beforehand. The location of these people were always a mystery. Some of them would devote themselves to reclusive training or searching for means to extend their longevity.
Some of their reclusive training could even be reclusive death training. They might even enter certain lands and not appear for ten thousand years. Hence, the outside world had no idea if they were alive or dead.
Yi Yun did not recognise the three people who had suddenly appeared.
However, Lin Xintong knew a lot more about the Tian Yuan world than him. Although she had never met the three people before, from their appearance and aura, she was able to guess their identities.
The truly legendary figures in the Tian Yuan world were actually only these few people.
