He took Grandma Thompson shopping and bought a lot of women's clothing, mostly conservative styles. The short shorts, pleated mini skirts, camisoles, and off-shoulder tops that William Thompson loved—none of them were purchased.

Grandma Thompson was unwilling to wear such revealing clothes. After all, more than twenty years ago, even among generally conservative women, it was rare to wear such exposed outfits. So, in Grandma Thompson's eyes, this era once again became unappealing.

After wandering around for quite a while, he finally remembered they hadn't bought underwear, so he took Grandma Thompson to buy some.

She was familiar with women's underwear, so she didn't insist on wearing a dudou or anything like that. After all, she had worn underwear more than twenty years ago. It's just that modern women's underwear made Grandma Thompson feel embarrassed.

If it wasn't lace, it was see-through, and even more outrageous, they actually displayed sexy lingerie openly.

William Thompson forced her to buy four or five sets of lace and see-through underwear. Grandma Thompson, blushing, muttered, "I hate this era, wearing such shameless clothes."

William Thompson didn't have time to pay attention to her grumbling, his eyes focused on the bra tag. Hmm, Grandma Thompson is a 34D.

What an impressively large bust.

After buying the clothes, they were ready to go home. He wasn't feeling well today; his kidney deficiency wasn't something a single night's sleep could fix.

On the roadside, they saw a shop selling traditional yogurt. Grandma Thompson insisted on having some, so William Thompson paid for two bottles. This kind of yogurt tasted average, was expensive, and not cost-effective. Only tourists from out of town would buy a few bottles to try.

Grandma Thompson had never had yogurt before. With the first sip, she was conquered by it—the sweet and sour flavor exploded on her taste buds. She squinted her eyes in happiness, a white milk mustache at the corner of her mouth. "So delicious, I like this era again."

Iron-willed Grandma Thompson, an entire era changed for a bottle of yogurt.

"Let's go, Wang Jingze. Once you know about Tmall and Yihaodian, you'll like this era even more."

"Who is Wang Jingze?"

……

He had class tomorrow. After returning home, he taught Grandma Thompson some basic ways to use household appliances. Although Grandma Thompson was from ancient times, fortunately she wasn't someone who had slept for a hundred years. She had a foundation in modern life, so a few simple explanations were enough for her to understand.

William Thompson then dug out a previously retired phone. It was fully charged and still usable, so he gave it to Grandma Thompson.

"William Thompson, next I'm going to teach you the method of cultivating qi." After her bath, with her hair still damp, Grandma Thompson sat cross-legged on the sofa and called out to William Thompson, who was playing PUBG.

"The method of cultivating qi?" He was stunned for a moment, then got excited, abandoning his game with an eager expression. "Is this cultivation?"

"Yeah, right, cultivation my foot," Grandma Thompson said irritably. "Refining essence into qi, refining qi into spirit—the art of cultivating qi is a technique humans have developed. In ancient times, the descendants of ancient demon bloodlines discovered that when the physical body reached a certain level, a sensation of qi would arise within. It's a kind of energy produced in the cells, and by training in a special way, it can nourish the body in return. Qi and essence benefit each other. When the sensation of qi becomes strong enough, it can even give rise to various abilities. Unlike the powers inherited from bloodlines, this is a system outside of bloodline power."

"This is also the only supernatural ability humans can master. Ordinary people find it very hard to develop a sense of qi because their cells aren't strong enough. For ancient demon blood descendants wanting to awaken their bloodline power, cultivating qi is the best way. It can stimulate the awakening of cells, thereby gaining the power dormant in their bloodline."

In ancient times, people didn't know the method of cultivating qi, so there was the saying of refining essence into qi—by training the body to make the cells produce a sense of qi. This was the earliest way of cultivating qi.

As the art of cultivating qi was continuously improved and developed, later generations no longer needed to temper their bodies to cultivate qi (only for bloodline descendants).

Throughout history, the methods of cultivating qi have been more or less the same, with some better than others, but the differences aren't great.

The core of cultivating qi is breathing exercises—absorbing and exhaling spiritual energy, making the internal organs resonate, first tempering the organs, then the body, working from the inside out. Internal martial arts follow this path.

William Thompson opened the window, letting the spiritual energy of heaven and earth flow into the room. Following Grandma Thompson's instructions, he sat cross-legged on the floor, palms up.

Grandma Thompson taught him the secret qi cultivation method passed down in the Li family, with the core mantra: Open the Heavenly Gate, close the Earthly Door.

Open the Heavenly Gate to gather innate energy, close the Earthly Door to guard the fetal breath.

The actual method: tighten the anus and contract the perineum, focus on opening the Baihui acupoint.

In plain terms, it's clenching your butt and opening your mind.

Clenching the butt is easy—every man has experienced that feeling.

As for how to open the Baihui acupoint, that's up to Grandma Thompson.

Opening the Baihui acupoint is the most important step in cultivating qi, called opening the Heavenly Gate. The breathing mantra is simple and easy to learn, but the Baihui acupoint is hard to open. Unless there's a qi cultivation expert assisting, ordinary people simply can't open it.

And without opening the Baihui acupoint, spiritual energy can't enter the dantian.

Thus, there's an old saying: "The immortal strokes my crown, tying my hair and granting me longevity."

As William Thompson followed the mantra to breathe, Grandma Thompson stepped forward, stretched out her slender jade hand, and placed it on the Baihui acupoint at the top of William Thompson's head.

With his eyes closed, William Thompson felt a warmth at the top of his head, as if a warm current was rushing in. Stimulated by this, a warm current also rose in his dantian.

The two warm currents converged in the middle dantian, then, following his breathing rhythm, traveled through all the meridians in his body. In the art of cultivating qi, when qi travels through the twelve main meridians, it's called the Small Heavenly Cycle. When it passes through the twelve main meridians and the Ren and Du meridians, it's called the Great Heavenly Cycle.
