Dreamcatcher

One night, Yu Hao, a college student who was at his wits' end, had an unexpected encounter with a mysterious visitor – "General" – who had a dream travelled. He led Yu Hao in solving the countless riddles that abounded in the realm of the conscious and lit up the fire beacons on the meandering Great Wall. Thereafter, the darkness retreated, the sun rose, and when the long night was thoroughly lit up, the him who existed, in reality, was reborn. 

The black dragon that roared, the lighthouse and demonic eye on the coastline, the rain forest before Chichén Itzá, the fierce beasts that wreaked havoc in the Colosseum…the bizarre projection of reality in one's consciousness reflected the hidden place that the sunlight, in reality, couldn't touch – the innumerable sins of the human heart. The journey of seizing dreams continues, and one can only hope that the sun will continue illuminating the human heart. Fire beacons on the Great Wall were lit up to signal a border invasion.
