… Borges

“I exist in the sunlight, the wind, between the heavens and the earth, and also in dreams.”

One night, Yu Hao, a college student who was at his wits’ end had an unexpected encounter with a mysterious visitor – “General” – who had 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.

REBORN OF THE LEGENDARY BEAST MASTER

The waves ripple around me,calling me in a whisper,Into the deepest part of the ocean.As I walk on the soft sand,the water sweeps over my feet,surrounding where I stand,giving me the sweetest sensation.Oh ocean,why do I feel so attracted to you?Why do I feel the tickling of your whispers?As it causes cold shivers down my spine.I could hear your gentle lullaby,It roars like a lion, yet so steady and honestJust like a refined diamond.Oh, sea, why do you call my name in a whisper?Caressing waves upon the shore,Once again you beckon me.Why do you show yourself at my doorstep?Why do I feel your presence everywhere I go?Why do you call me so desperately?I want to know, cause when the sea calls?Who will answer?
