Feng Shen Ji

From Easy Going Scans:

The Great Shang dynasty has been in power for many years, but the Gods have found fault with the new emperor. Instead of submitting to their will at the expense of his people, the emperor resolves to throw off the Gods’ yoke and free humanity. However, this means not only will he face the Gods, but also a rival, the young Zhou—who submits to the Gods’ will for nothing but his own purposes!

The fate of the dynasty, nay, the fate of all humanity will be determined by this great battle between the forces of Heaven and Earth!
