Inside the villa, Lin You sat at the coffee table in the living room, deep in thought, staring at the complex array diagram on the screen.

Lin Xue, Lin Ya, and Lin Shan were lazily sunbathing in the rooftop sunroom.

They were the most important people to him in this world.

Originally, when I was physically transported to this world, I didn't feel much of a sense of belonging.

But with them, the meaning of a stable life becomes different.

Seeing this heartwarming scene, Lin Yu felt much more determined.

The truth about the potential crisis facing humanity, which Yang Mu previously revealed.

It felt like a heavy stone weighing on Lin Yu's heart.

Originally, all he wanted was to become stronger, protect his family, and live a comfortable life in this world.

But now, he clearly realizes that being just ordinary strong is not enough to qualify him to "lie flat".

Even if one becomes the strongest human, it is not necessarily possible to withstand the onslaught from other powerful races.

This anxiety about the future did not discourage him.

Instead, it transformed into an even stronger sense of urgency.

If being the strongest among humans isn't enough, then become the strongest among all races!

Improving one's own strength is always the fundamental way to cope with all unknown challenges.

Of course, a safe haven is also necessary at this stage.

The protective array of runes is essential for safeguarding one's "home".

He sat down next to Lin You, his gaze refocusing on the intricate lines, his eyes more intent than before.

"Lin You, let's continue."

Time waits for no one.

"Yes, Your Majesty." Lin You sensed a calm and composed aura emanating from Lin Yu.

She also subconsciously straightened her posture.

For the next three days, Lin Yu entered a state of "seclusion".

He only left the house once during the journey.

The destination was the school's pharmaceutical preparation center.

He had previously contacted a Class B pharmacist who was on temporary assignment at the school through Principal Wang Defa.

Upon meeting the other party, Lin Yu took out 10 precious materials—

"Blood of an aged dragon".

This was the reward he received when he broke the national record for "Venomous Forest" multiple times.

It has always been kept safe in my multi-purpose waist bag.

Each "Blood of an Old Dragon" contains the blood of a dragon.

Even though the dragon is old, its life energy is still considerable.

This blood is the material used to make Grade C health potions.

Each batch can reliably produce 6 vials of medicine.

"Teacher, I'll have to trouble you with this." Lin Yu handed the materials to the elderly pharmacist with gray hair.

The old apothecary took the materials, examined them carefully, and a look of surprise appeared in his eyes: "High-quality blood from an old dragon is indeed rare."

He looked Lin Yu up and down again, and exclaimed in admiration:

"This young man is indeed handsome and extraordinary!"

"You've become quite famous at school lately; I've heard a lot about you."

"Don't worry, I'll take the job."

"Principal Wang also spoke with me, and our school will cover the production costs."

"I'll contact you when it's ready, and you can come and pick it up then."

"Thank you, teacher," Lin Yu said sincerely.

The reason he rushed to make the potion at this time was because all the team members had now reached level 30.

Grade C fitness potions are only effective if taken before reaching level 31.

Once they break through level 31, taking potions will be a waste.

The experience required to go from level 30 to 31 is not low.

However, given their current dungeon-clearing efficiency, coupled with the 200% experience bonus provided by [The Primal Hunter's Teachings], they are still capable of clearing dungeons efficiently.

I'm afraid it would only take half a day of running dungeons to break through the level barrier.

We must hurry.

Aside from handling this matter, these three days have been filled with other things.

Lin Yu devoted almost all her energy to learning and practicing the inscription of rune arrays.

Seeing their master so focused, Lin Xue, Lin Ya, and Lin Shan tacitly refrained from disturbing him.

The villa was so quiet that only the sounds of Lin Yu and Lin You discussing their research could be heard.

Under intense study and practice, Lin Yu's progress is also clearly visible.

With the guidance of Lin You, the "technical consultant," Lin Yu's grasp of the frequency of rune resonance and the stability of energy circuits has become increasingly precise.

He has been able to gain a deep understanding of the "rules" behind those complex structures.

Skillfully using "blood ink," they depicted one rune array module after another.

Of course, these three days were not all boring study sessions.

After all, health is the foundation of everything, and a balance between work and rest is essential for long-term health.

Every night before going to bed, Lin Yu would set aside time to give Lin Xue and Lin Shan "tutoring lessons".

The "lessons" given to Lam Suet usually take place in the gym or training room, focusing on practical sparring.

We occasionally discuss technical issues, although the discussions might be rather... heated.

The "lessons" given to Lin Shan were mostly in her bedroom or study.

After the last "lesson," this owl seems to have opened a door to a new world, and her thirst for knowledge has become especially strong.

Her "tutoring sessions" often begin with asking a difficult question, and then, without realizing it, the topics discussed will drift to a broader field, requiring Ms. Lin to provide patient and meticulous "one-on-one in-depth tutoring".

Lin Shan has an extremely serious attitude towards learning, but sometimes she is too enthusiastic when it comes to practice, which makes Teacher Lin a little overwhelmed.

He often needs to exert his physical strength, which is over a thousand, just to barely maintain the "dignity of a teacher."

As for Lin Ya?

Little Glutton Bear has been learning how to order takeout these past few days.

I change my outfit every day so that I never repeat myself.

In this tense and fulfilling rhythm, the time came to the afternoon of the third day.

In the center of the villa's underground warehouse, a clean area has been cleared out.

Lin Yu and Lin You stood side by side, their expressions serious.

On the floor in front of them, a circular basic array framework with a diameter of about three meters had been outlined using specially made energy-conducting powder.

At the core node of the framework, several magic crystals emitting a soft white light were placed.

In Lin Yu's hand was the legendary [Eternally Pure Swan Feather].

The pen body is as smooth and warm as jade, and the pure white feather nib contains a vast and sacred aura.

Beside it, in a small crystal dish, lay a small amount of crystal-clear "Eternal Pure Swan's Foot Bath Water".

This ink truly lives up to its epic-grade material status, continuously emitting rich, sacred energy fluctuations.

After three days of intensive theoretical study and hundreds of simulation exercises, Lin Yu felt that his understanding of rune arrays had reached a critical point.

It's time to make the first formal attempt at character portrayal.

He took a deep breath and closed his eyes.

Let the complete structure of the [Holy Protection Counterattack Rune Array] be revealed.

This includes every detail of the runes, the direction of every energy loop, and the connection of every node.

I went through them all in my mind with perfect clarity.

Beside her, Lin You also held her breath and focused, her energy body pulsating slightly, ready to provide assistance at any time.

Opening her eyes, Lin Yu's gaze became incredibly focused and calm.

He picked up the talisman brush and gently dipped it into a little epic talisman ink.

The moment the pen tip touched the starting point of the array frame, a gentle yet powerful divine energy surged into Lin Yu's arm along the pen, resonating with his own magical power.

His wrist moved steadily, the tip of the pen flowing with crystalline light, precisely landing on the lines outlined by the energy-conducting powder.

His movements were slow, and therefore exceptionally steady.

Every stroke of his pen was imbued with his full spiritual energy.

Sweat gradually seeped from his forehead, but his arms did not tremble at all.

Lin You observed intently from the side.

Her "vision" could clearly "see" that energy, guided by the talisman, flowed, converged, and took shape along a predetermined trajectory.

Her brain was working at lightning speed, constantly performing real-time calculations to ensure that the energy flow was accurate.

And promptly report any subtle energy fluctuations to Lin Yu.

The characterization process is about two-thirds complete, and then it enters the most complex central linkage module.

This requires simultaneously constructing seven different functional rune groups and activating them synchronously in a specific structure to create a synergistic effect.

Even a millimeter deviation in any set can lead to a cascading collapse.

Lin Yu's breathing became slightly rapid, indicating a significant depletion of her mental energy.

Following the feeling he had developed through countless practice sessions, he traced a delicate arc with the tip of his pen, connecting the two key points—

Om-!

A calming humming sound rang out.

The previously sluggish energy flow instantly became smooth.

The seven rune sets simultaneously lit up with a soft golden light, perfectly synchronized!

Central linkage module successfully built!

The subsequent character development went much more smoothly.

Lin Yu got into the swing of things and became more and more comfortable drawing.

As the final arc falls and perfectly closes with the foundational rune at the starting point—

The entire array suddenly burst forth with a dazzling golden light!

A vast and pure sacred aura, carrying supreme majesty, soared into the sky and enveloped the entire villa!

The light lasted for several seconds before slowly fading away.

In the end, only one complete rune array remained on the ground, shimmering with a faint golden light.

The core of the rune array automatically connects to the villa's energy hub and the reserved protective array interface.

The magic crystals at several base positions shone steadily, providing the rune array with a continuous and gentle energy.

[Divine Protection Counterattack Rune Array] successfully inscribed!

Lin Yu let out a long sigh of relief, feeling somewhat weak.

But he was incredibly excited.

He succeeded!

With the help of his super assistant Lin You, he mastered the Heavenly Rank Rune Array in just three days and successfully inscribed it!

Moreover, thanks to the incorporation of the Star Moon Elf magic rune technology provided by Lin You, the actual effect of this rune array is even better than the standard version was predicted.

It not only improved the strength of the protection module, but also reduced the energy consumption for normal maintenance!

"Congratulations, Your Excellency! A resounding success on your first attempt!"

Lin You also appeared very excited, her energy body rippling with joy.

This not only reflects her own contribution, but also demonstrates her worth before the Lord.

Lin Yu wiped the sweat from her forehead, a satisfied smile spreading across her face.

With this talisman array, the safety of the home is finally guaranteed.

Just then, his phone rang.

It was the old pharmacist who called.

"Lin Yu, your Grade C fitness potion has been completed, a total of 60 vials."

"If it's convenient for you now, you can come and pick it up."

"Great!" Lin Yu's spirits lifted.

Good things come in pairs!

"Thank you, teacher, I'll be right there!"

He called Lin Xue and Lin Ya, who were practicing in the training room upstairs, and Lin Shan, who came downstairs after hearing the commotion.

The four of them went out again and headed to the school's pharmaceutical preparation center.

Lin Yu received a constant temperature storage box from the old pharmacist.

Inside, 60 pale gold medicine bottles were neatly stacked.

Each vial of medicine was crystal clear, exuding a rich aura of life.

Back at the villa, Lin Yu eagerly opened the box and distributed the medicine to the three girls.

"This is a Grade C health-enhancing potion. It must be taken before breaking through to level 31, and it can only be effective a maximum of three times."

Lin Yu explained, and then picked up three sticks herself.

"It can permanently improve our physical condition, and the effect is very practical."

"Come on, let's drink together."

The three girls obediently accepted the medicine.

They followed Lin Yu's example, uncorking the bottle, and a refreshing medicinal fragrance immediately filled the air.

"Drink it!" Lin Yu was the first to tilt his head back and swallow the three vials of medicine in turn.

The warm medicine flowed down his throat, immediately transforming into streams of warmth that flowed through his limbs and bones.

It penetrates into every inch of muscle, bone, internal organs, and even deep into cells.

He could clearly feel his vitality being slowly strengthened.

The three beast girls followed Lin Yu's instructions and took the medicine one after another.

Lin Ya even smacked her lips and muttered, "It's a little sweet, but it doesn't taste as good as cola."

The medicine takes effect very quickly.

Lin Yu immediately brought up the attribute panel to check.

His total attribute points, after the previous level increase, have exceeded 3200.

The three potions can boost a total of 9%.

His physical attributes increased by nearly 300 points!

Health points also increase significantly.

From just over 10,000 points before, it instantly jumped to over 15000 points!

This amount of health is equivalent to the combined health of all members of a level 30 top-tier five-person squad!

Combined with the shield and damage reduction effects provided by various skills.

He became a veritable human-shaped BOSS!

The combined total of the three beast girls' attributes also exceeded 2500 points.

After taking three doses of the medicine, their physical condition improved by more than 200 points.

Lin Xue's health points jumped from over 7000 to over 9000!

Combined with her powerful shield skill and exaggerated damage reduction, she truly became an "iron front line" that was impossible to damage.

The health output of Lin Ya and Lin Shan, the two "squishy" characters, increased from over 2000 to over 4000.

That's equivalent to two Liu Huis!

That's enough health to be a front-line tank.

Their survivability has been greatly enhanced, and their margin for error in battle has naturally increased significantly.

Feeling the surging life force within them, all four felt a surge of heartfelt joy.

The improvement of one's strength is always tangible and brings the greatest sense of security.

Now that the team's strength has improved significantly, Lin Yu naturally set his sights on the school's dungeons.

The national records for level 25 and 30 dungeons have yet to be set, and they have not yet left their names.

I've been conserving my energy for so long.

Now is the time to reclaim the reward that is rightfully yours.

The four members of the team changed their equipment and headed towards the school's dungeon area!

-

Thank you all for your continued support. I wish you all good health, prosperity, and success in your careers in 2026!
