Another day had passed.
The black key hanging on his back became even heavier, forcing Shen Feng to maintain a flying height of just over a meter.
He looked up.
In the distance, he could see an ancient golden building suspended in the sky.
Around this structure, a green wooden block was rotating.
The closer he got, the more oppressive the force in the sky became. At Shen Feng's current location, even cultivators at the middle stage of the Golden Core might not be able to withstand it much longer.
However, for Shen Feng, this oppressive force was nothing to worry about. What he couldn't bear was the great black key on his back. Of course, if he used a strength-based Immortal Technique, he would be much more at ease, but now was not the time to waste too much Spiritual Energy.
Upon seeing the green wooden block, Shen Feng was completely reassured. He guessed that to unlock the ancient golden building in the sky, the black key on his back was absolutely necessary.
