"One hundred and fifty years." She said, her clear eyes gazing into the distance, gradually emptying, her voice becoming ethereal: "Every time I sleep and wake, the world has changed. Constantly changing. But I always remain the same; time has lost its law on me..."

One hundred and fifty years...

William Thompson almost peed himself.

Grandma Thompson suddenly turned around, the aura of a worldly master gone again, now like a spoiled young lady, glaring: "Where are the snacks? If the snacks aren't tasty, I'll beat the crap out of you."

William Thompson obediently offered up spicy sticks and potato chips.

"Hiss... hiss... so good... hiss, how can it be this delicious... I like this era... hiss, so spicy." Grandma Thompson munched on the spicy sticks, fanning herself with her small hand, tears welling up at the corners of her eyes from the spiciness.

Watching Grandma Thompson fall in love with this era all over again, William Thompson had a phrase pop into his mind: The iron-willed Wang Jingze, who would sell out his country for a bowl of fried rice.

"Of course," William Thompson gave a thumbs up and agreed, "Weilong brand spicy sticks, a childhood memory of mine."

William Thompson watched as she happily finished the whole pack of spicy sticks, gulped down two cups of water, then chomped through the potato chips, patted her little belly, and lazily sprawled on the sofa, saying in a sweet voice, "Let's have a talk. Before your dad sealed me away again, he did entrust me to be your life mentor."

"Okay, Grandma Thompson." William Thompson sat up straight, finally, it was happening—he was a bit impatient to figure everything out.

The living room fell silent. After a few minutes, William Thompson said, "Grandma Thompson?"

Grandma Thompson rolled her eyes and snapped, "What?"

"You can start now."

"I haven't read much, need to organize my thoughts. Let me ponder for a bit, don't interrupt."

A few more minutes passed. She adjusted into a duck-sit posture, left arm hugging her chest, right hand propping up her chin, "Do you know about the existence of ancient demons?"

William Thompson cooperatively shook his head, "No."

"They were powerful beings from ancient times, before humans learned to record history, even before humans were born into this world. Ancient demons ruled this land, they were the masters of this planet."

"The overlords of ancient times should be dinosaurs, right?"

"Earth's hundreds of thousands of years of history hide too many unknown secrets and past events. Dinosaurs were just creatures that appeared during a certain period."

"It's billions of years, Grandma Thompson." William Thompson corrected.

"..." Grandma Thompson huffed, "I'm not talking anymore."

What, am I not allowed to save face?

"...I shouldn't have interrupted, please continue."

Looks like you really haven't read much, old lady.

Grandma Thompson said seriously, "Humans have never been the only intelligent beings throughout history. As early as ancient times, there existed creatures with both wisdom and power, and they were nature's favorites, born with unparalleled strength. Moving mountains and filling seas was no legend for them."

William Thompson retorted, "That's way too far-fetched, why not say they could ascend to immortality in broad daylight and join the ranks of the gods?"

"Every species in the world has its unique racial talents. Some animals' abilities are superpowers to humans. Superpowers aren't nonexistent, it's just that humans themselves don't have them, so they instinctively dismiss them as absurd. Actually, these are abilities granted by nature. Ancient demons were the same. In fact, humanity's longing for ascension and immortality isn't pure fantasy—they really did witness scenes of flying and burrowing. Ancient demons were powerful and terrifying, but ultimately couldn't defeat time, and were drowned in the long river of history."

"Wait, if ancient demons have already perished in history, are we their descendants?" William Thompson thought of the contents of the will.

"Although ancient demons are extinct, their genetic spark hasn't died out. According to the evolution theory proposed by Westerners, every species on Earth shares commonalities in their genes. We humans have ancient demon genes in us, as do animals and plants. It can exist in humans, or in dogs."

"Please continue, Darwin's coffin lid is being held down by his grandson for you." William Thompson said.

"Ancient demon bloodlines run through all of human history. They possess abilities humans can't comprehend, as well as powerful physiques. They weren't low-key, appearing frequently in history, but those in power always deliberately downplayed the existence of the bloodlines. By modern times, ancient demon bloodlines have completely hidden in the shadows of history," Grandma Thompson said.

"If that's the case, wouldn't society be in chaos?" William Thompson's worldview was struggling: "If I had the ability to leap over roofs and walls, I'd definitely be a flower thief, a new groom every night, a new bride every day or something."

He always believed that human nature is a mix of good and evil, and the greater the power, the greater the responsibility. Likewise, the greater the power, the greater the potential harm.

"That's all you aspire to?" Grandma Thompson spat, "Since ancient times, ancient demon bloodlines have been typical of using martial power to break the law. Most of the prominent families among the bloodlines served the imperial court. Our Li family was once a renowned clan. In modern times, in 1949, the Buddhist and Taoist Association officially became the law enforcers of the bloodline world, managing all bloodlines. If you think bloodlines can run amok and do whatever they want, you're dead wrong. Bloodlines believe in the law of the jungle, but the premise is that they must not disturb social order."
