He has been reincarnated through countless worlds, adorned with billions of mythological terms!

Yun Yi stood up, patted the grass clippings off his trousers, and glanced at the clump of moss at his feet that had been sucked dry and was now slightly wilted.

The spiritual energy seepage point hadn't dried up, but the flow rate had slowed down significantly, as if the spring had absorbed the water that had accumulated over many days and needed time to recharge—at least until next week.

For the next few weeks, Yunyi went to the wilderness once a week.

The flow of spiritual energy at that seepage point slowed down more and more: from recovering to the original level in a week, to two weeks, and then to a month.

Yunyi later found another seepage point by the river and began to absorb it in rotation.

Three months passed just like that.

In the seventh week, Yun Yi's cultivation reached the peak of Foundation Establishment.

He stopped.

Above the Foundation Establishment stage lies the Golden Core.

The Golden Elixir is not something that can be achieved in a day; it requires the accumulation of a large amount of spiritual energy and a sufficiently stable foundation.

—Of course, the main concern was Yun Yi's hesitation: whether or not to embark on the path of achieving the Golden Core in this lifetime.

There is no doubt that the Golden Core of the previous life was powerful, but there is also no doubt that it was difficult to achieve.

After a moment of contemplation, Yun Yi finally gave up the Nine-Patterned Golden Elixir from his previous life.

The key to my success in the previous life was my innate wisdom.

The cost, consumption, and computational workload required for that method of condensing the Golden Core are too enormous; it may not be possible to replicate it in this lifetime.

Even if one succeeds by chance, without the innate seed of enlightenment, the Nascent Soul stage is another major hurdle, and one will likely be stuck there for life.

After careful consideration, Yun Yi decided that he would simply follow the established path of the immortal cultivation system in this lifetime and refrain from any further unorthodox actions.

Moreover, in this life he is destined for the path of gods, so he doesn't need to cultivate diligently—he just needs to play his role well.

However, Yun Yi did not use all his spiritual energy to improve his cultivation.

Each time he absorbed spiritual energy, he would store a portion of it, mainly to study the energy and see if he could create something useful.

After three months, the amount of spiritual energy he had stored was equivalent to the entire spiritual power reserve of a Golden Core cultivator in the early stage.

After completing the final storage, Yunyi returned to the villa from the wilderness and entered the underground laboratory.

On the laboratory shelves, there are a dozen rows of glass bottles neatly arranged.

From the first generation to the seventh generation, samples of each generation of gene therapy are archived.

He picked up the seventh-generation bottle and shook it under the light.

The pale golden liquid is clearer and more fluid than the first generation, and gleams with an amber luster under the light.

Seven years have passed.

It has been seven years since the first gene-based drug was formulated.

Seven generations of products, each iteration representing a qualitative leap.

First generation: Tenfold improvement in physical fitness.

Second generation: Twenty times.

Third generation: Fifty times.

Fourth generation: Targeted optimization—vision, hearing, neural reaction speed, cell regeneration capacity, each pathway can be individually enhanced.

Fifth generation: Fusion optimization - multiple paths are enhanced simultaneously without conflict and can be stacked.

Sixth Generation: Gene Lock Initially Unlocked - Physical Fitness Limit Increased from Hundreds to Thousands of Times.

Seventh generation: Stabilization - All enhancements are controllable, reversible, and sustainable, with no side effects.

Now, he needs to give these medications to his family.

Because the world is changing.

The number of spiritual energy seepage points is increasing—it took him three months to find seven points, and three more appeared last month, with the spiritual energy concentration at the new seepage points being higher than the old ones.

Yunyi had no idea what this meant.

But he knew one thing: the world was about to change.

His family needs to have the ability to protect themselves.

Yun brocade.

Yun Yao.

Then, Yun Jingran and Shen Ruoqing.

Yun Jin stood under the lights of the underground laboratory, wearing a simple white T-shirt and jeans, her ponytail tied high, revealing her smooth forehead and delicate features.

"What is this?"

She looked at the pale gold potion in Yun Yi's hand and raised an eyebrow.

Vitamins.

Yun Yi remained unfazed.

Yun Jin stared at him for three seconds.

"You don't still think of me as a little kid, do you?"

"This time it's for real."

"Aren't you ashamed to lie to your sister?"

Yun Yi blinked.

Yun Jin sighed, took the medicine, unscrewed the cap, and drank it all in one gulp.

The moment the medicine entered her mouth, her body stiffened slightly.

A warm liquid spread from my throat to my limbs and bones, like a warm stream flowing through my veins, tingling and numb wherever it flowed, as if every cell was trembling gently.

Then, everything returned to calm.

"alright?"

"alright."

"that's all?"

"What else do you want?"

Yun Jin stretched her shoulders, rotated her neck, and did a few squats.

"It seems... I don't feel anything."

"You'll see once you go for a run."

Yun Jin walked out of the basement with some doubt and ran around the mountain road behind the villa—the mountain road was about five kilometers long.

It usually takes her ten minutes to run one lap, and she sweats afterward.

Today, she ran a lap and came back in just three minutes. She wasn't even out of breath or red-faced, and she even felt like she hadn't had enough.

"this……"

Vitamins.

Yun Yi leaned against the doorway, hands in his pockets, looking innocent.

Yun Jin opened her mouth, then closed it.

He opened his mouth again, then closed it again.

In the end, she didn't say anything, but just walked over and ruffled Yun Yi's hair vigorously.

Be careful.

"Um."

"Don't let anyone find out."

"Um."

"What's wrong? Tell your sister."

"Um."

Yun Jin is gone.

Yunyi leaned against the doorway, watching his sister's figure disappear at the top of the stairs, a slight smile curving his lips.

Then he turned around and picked up the second bottle of medicine.

Go find Yun Yao.

Yun Yao's bedroom is on the third floor of the villa. The sticker on the door has been changed from "Yun Yao's Little Nest" to "Yun Yao's Big Nest", but the plush rabbit pendant on the doorknob is still there, only the color has faded a lot.

Yun Yi knocked on the door.

"sister."

"Come in."

He pushed the door open and went in.

Yun Yao was lying on the bed looking at her phone, her legs dangling back and forth, a strawberry lollipop in her mouth, filling the air with a sweet aroma.

Fourteen-year-old Yun Yao is even more beautiful than she was when she was a child.

Her features resembled Shen Ruoqing's, so exquisite they looked like they had been painted. Her skin was so white it glowed, and her hair was black and shiny, cascading over her shoulders like a piece of satin.

But she still has the same personality—she doesn't want to say a word to anyone except her younger brother and sister.

"what?"

Yun Yao didn't even look up, asking vaguely.

Yun Yi walked over, sat down beside her bed, and handed her the pale gold potion in his hand.

"I drank it."

Yun Yao finally raised her head, glanced at the medicine, and then at Yun Yi.

"What is this?"

"Things that are good for you."

Yun Yao didn't ask any questions. She took the medicine, unscrewed the cap, and drank it all in one go.

"alright."

She returned the empty bottle to Yun Yi and continued looking down at her phone.

Yunyi glanced at her screen—it was an animated film, the main character being a pink rabbit.

"How old are you to still be watching this?"

"Mind your own business."
