Giant Kui wielded his eight giant clubs as he marched to the golden city. While running, he roared thunderously and released torrents of green mist, merging into the surrounding towering trees. Absorbing Giant Kui's power, these trees immediately turned into hundreds of meters tall giants, following behind Giant Kui while growling hoarsely.
Gradually, a formidable army emerged around Giant Kui, and the forest left behind by him was emptied.
Surprisingly, while running, flowers had been blooming and withering on the crowns of all tree giants. Fruits matured on their branches, fell on the ground, rooted, and sprouted in the soft soil. Before long, a giant number of saplings drilled out of the ground.
Clearly, all tree giants under Giant Kui's command prepared themselves to die on the battleground. Before the war between them and the invaders began, they had left their 'descendants' in this world.
