For millennia, he had slumbered deep within the heart of the sacred mountain, his majestic form obscured by time and forgotten by history. His black and orange chassis bore the regal features of a lion, while the mech's once vibrant systems lay dormant, the echoes of a bygone era. But now, a cacophony of prayers – voices thick with fear and despair – stirred him from his deep sleep.

Like a heartbeat, the code of his purpose pulsed back into existence. Protect the weak. Ensure their survival. Destroy evil on sight. Each directive boomed through his consciousness as his systems began their slow reawakening, like an ancient giant roused from its slumber. His engines, quiet for ages, suddenly roared back to life with a sound that shook the mountain, dislodging rocks and sending echoes rippling across the valley.

With a ground-shaking rumble, he started to pull himself free from his rocky prison, his massive limbs displacing millennia worth of earth and stone. Crashing through the final layers of the mountain, he emerged into the world, his fiery mane flaring in the wind and his mechanical eyes aglow with purpose. His systems hummed with renewed life as they assessed the situation, his gaze sweeping across the terrain.

His lion's mouth opened, releasing a brilliant soft green light, his roar resonating through the valley, a clear announcement of his awakening. Each thunderous step sent vibrations through the earth, his heavy form descending towards the praying village nestled at the base of the mountain.

The villagers and monks gasped, their prayers cut short by the overwhelming sight of the awakened guardian. The ancient and massive being was as much a part of their myths as the mountain itself. A trembling monk, old with wisdom and age, ushered a name that hadn't been spoken aloud in centuries, his voice filled with a strange mixture of fear and hope: "Dòu Shì Shī Hún..." The protector from a forgotten age had finally awakened.
