The primordial era began with the Upper Cave Man.

"Lingtai Fangcun Mountain, Xieyue Sanxing Cave..."

"Where is this?"

An innocent and ignorant child, with a seven-colored gourd on his head, stood in front of a door, sucking his fingers. On either side of the door stood two wooden couplets.

The words a child is muttering are written on it.

"How do I know these words?" The little boy shrank his neck, then peeked out, and finally exhaled.

There was a spark of fire in that breath, but the sparks crackled in the air for a moment before being extinguished without a trace, leaving only a little heat.

"Grandpa! Grandpa!" The little boy panicked immediately and hurriedly called out to his surroundings.

However, no one responded; his grandfather was not around.

The little child panicked for a moment, looking around and searching everywhere, his little feet running all over the flat square paved with marble slabs in front of the cave entrance.

But no matter which direction he ran in, he always ended up back in front of the cave entrance.

"Grandpa, grandpa, grandpa, grandpa... Waaaaah..."

The chubby baby eventually gave up and started rubbing his eyes and crying loudly in front of the cave entrance.

"Huluwa, Huluwa..."

Just as he was crying, a gentle call came from the cave door.

The chubby baby shook its big head, looking around: "Who is it? Are they calling me?"

"Yes, it's you. I'm here." The call from the cave grew softer, as if one could imagine a kind old man with a white beard smiling and talking to him.

"Who are you?" The chubby baby nervously sucked on his fingers and called out softly into the cave.

"My name is Bodhi, and I am your master," came the reply from inside the cave.

"What is a master?" The chubby child couldn't understand the meaning of the word.

A response came from inside the cave: "The one who taught you the skills to eat and live in this world is your master."

"Then is my grandfather my master?" The chubby child was very clever and immediately understood the explanation, and even applied it to other situations.

"Yes, your grandfather was also your master," came the affirmative reply from the cave.

"Then you're my grandpa too?" the chubby child asked, bewildered and curious.

"Grandpa is grandpa, and master is master. Grandpa can be master, but master is not necessarily grandpa." The explanation came again from the cave.

The chubby baby finally understood.

"But you haven't even given me any food yet, how come you're my master?"

Hey, this kid isn't stupid after all.

"But I'm already teaching you," came the voice from inside the cave.

"Really?" the chubby baby asked, puzzled.

"Look at the couplet at the entrance, do you recognize what it says now?" came the reply from inside the cave.

"Okay, I understand." The chubby baby nodded.

"Did you understand it before?"

The chubby baby shook his head.

"So now you understand, doesn't that mean I taught you?"

The chubby baby nodded subconsciously.

He was just young and felt something was strange about it, but he couldn't figure it out no matter what he did.

That's settled then.

"Can this be eaten?" the chubby baby asked.

"Yes, you can earn money by reading and writing."

"Money? What's that?"

"Something that lets you buy whatever you want to eat."

The two continued their question-and-answer session for a long time, but the chubby baby never entered the cave.

Soon, a loud, booming shout broke the harmonious silence of the question and answer.

"My dear grandson, my dear grandson, wake up, it's time to pee."

Grandpa's call reached the chubby baby's ears.

"grandfather?"

"Go ahead, come back tomorrow night."

The chubby child then felt as if he was instantly enveloped in a thick fog. After the fog dissipated, his grandfather's kind and gentle face appeared before him.

"Grandpa, Grandpa, I had a dream!" the chubby baby giggled.

"Oh? What kind of dream?" A strange look flashed across the white-bearded old man's face.

"I dreamt about... uh, I forgot, I can't remember Grandpa." The chubby child said somewhat disappointedly.

"It's okay, it's okay. It's just a dream. I dream all the time, and I forget about it when I wake up. It's normal. Let's go pee." (End of Chapter)
