So it's a key

What was that?

A single door had killed a true immortal. This was too terrifying.

Lu Ming's heart was in turmoil and he could not calm down.

At the same time, he was even more puzzled. When the door appeared earlier, the book in the storage ring shone brightly and almost flew out of the storage ring. Fortunately, Lu Ming managed to suppress it.

Could it be that the target of the book was that door?

In the end, Lu Ming decided to take a look. Of course, he could not enter the door. He only planned to watch from a distance.

What a joke. A true immortal was dead. He didn't want to die.

He headed in the direction of the door. Not long after, Lu Ming saw a huge Canyon. On both sides of the canyon were two majestic peaks.

In the middle of the canyon stood a stone door.

The stone door was more than ten meters tall. There was no door frame, and the inside of the door was filled with hazy light.
