He was resurrected indefinitely and handed over to the state by the headmistress.

"Xiao Lu, this is Grandpa's personal contact number. Contact me anytime if you need anything!"

Old Li quickly changed the subject, taking out a specially made jade talisman.

He touched Lu Chen's communication token.

"Yes, yes, and mine too!"

"This is mine!"

Soon, Lu Chen's communication token had more than a dozen highly encrypted private communication numbers added to it.

These numbers,

Each one represents a powerful figure whose mere stomp of the foot could shake the entire nation.

It's a talisman that you can't buy no matter how much money you spend elsewhere.

"Hey, Little Lu, come with Grandpa Feng!"

Feng Qingyang, rubbing his hands together excitedly, grabbed Lu Chen.

"Grandpa Feng has been bored these past few years, so I've been tinkering with a few 'good things,' but I've never dared to try them out."

"With you here, everything's fine! Come on, let's go to my secret potion lab!"

He was both a master swordsman and a mathematician obsessed with potion-making.

Lu Chen had no choice but to be pulled away by Feng Qingyang.

Soon they arrived at a laboratory filled with bottles, jars, various instruments, and strange medicinal herbs.

"Look, there are several newly developed medicines here,"

Feng Qingyang pointed at several strangely colored bottles, his eyes gleaming.

"I wasn't confident before, so I didn't dare to try it on myself, for fear of dying."

With you here, there's no problem!

Quickly, mark me with your abilities!

Lu Chen's lips twitched, and he had no choice but to do as he was told.

Mark Feng Qingyang with a resurrection mark.

"alright!"

Feng Qingyang eagerly picked up a bottle of potion bubbling with purple light.

He tilted his head back and poured it down.

The next second, his face turned a mixture of red and blue.

My body was trembling violently, and it felt as if countless insects were wriggling under my skin.

"puff!"

With a muffled thud, Feng Qingyang exploded, turning into a cloud of blood mist!

"Resurrection!" Lu Chen's eyelids twitched, and he immediately activated his ability.

[Ding! Feng Qingyang successfully revived, all attributes +1!]

A flash of green light, and Feng Qingyang reappeared unharmed, stroking his chin thoughtfully:

"No, the energy ratio is wrong... It's too stimulating, the meridians can't handle it..."

I've got it! We should replace the 'Dragon's Blood Grass' with the gentler 'Ground Lotus'...

He completely disregarded the fact that he had just "died" once.

He immediately rushed to the lab bench and started fiddling with things again.

Lu Chen: "..."

Over the next few days, Lu Chen became the busiest person in this special secret realm.

He wasn't accompanying Grandpa Feng in testing various new medicines with bizarre effects and alarming side effects.

Grandma Zhu dragged me there to try out her newly researched "Nine-Turn Golden Needle" acupuncture technique, which she claimed could stimulate the body's potential.

Or perhaps they were captured by the Heavenly Grandfather to test his improved body-refining techniques, which were said to be able to break through the limits of the human body but were extremely dangerous...

Every experiment was incredibly dangerous.

Fortunately, with Lu Chen's resurrection ability as a backup, the test subjects' lives can be completely saved.

However, the fear and pain of those repeated "deaths"

It still made Lu Chen's heart pound.

I have the utmost respect for the "scientific research spirit" of all the grandparents.

Of course, in this process,

Lu Chen also became very familiar with these old heroes who had different personalities but were all generous and sincere.

They truly loved him like their own grandson.

Although the way they "show affection" can sometimes be a little scary.

And so, a week flew by in a fulfilling "experiment" and a warm "family" atmosphere.

That day, Cold Frost appeared silently in the secret realm once again.

The news she brought instantly turned the previously relaxed and cheerful atmosphere heavy.

"First Heaven, East 37th Defense Line, the spatial rift is extremely unstable."

A large-scale gathering of demons has been detected, putting immense pressure on the defense line, which could collapse at any moment.

The garrisoned corps requested emergency support.

Leng Shuang's voice remained cold and aloof, but the content of her words sent a chill down everyone's spine.

"Damn demon!"

Tie Shanhe slammed his fist on the stone table, instantly reducing it to dust. A fierce fighting spirit ignited in his eyes.

"I'm itching for a good fight, let's go have some fun!"

"Dude, calm down."

Shi Qianjun pressed down on his shoulder and said in a deep voice,

"The situation at East Line 37 is special; there are ancient remnants of restrictions there."

If an entity of an excessively high level enters, its strength will be greatly suppressed, and there is even a risk of its demise.

If we go, we might not be able to unleash our full potential.

On the contrary, they might find themselves in danger due to the suppression of the rules.

Upon hearing this, all the heroes calmed down and frowned.

They are not afraid of dying, but they are afraid of dying in vain.

In that special area, they might have lost only one-tenth of their original strength.

Facing a tidal wave of demons, it may not be possible to turn the tide of battle.

Leng Shuang's gaze slowly fell on Lu Chen, who was helping Feng Qingyang record experimental data.

"Therefore, the higher-ups have decided," Leng Shuang's cold voice rang out.

"Dispatch an elite assault team of level 100 or below to provide support."

At the same time, a highly reliable support character with strong healing abilities is required to accompany them.

Her meaning was self-evident.

Lu Chen raised his head and met Leng Shuang's gaze, as well as the complicated looks from the grandfathers and grandmothers around him.

"The fighting there is fierce, and the casualties will be heavy."

Leng Shuang looked at Lu Chen, her tone calm yet carrying a hint of solemnity.

"But as long as you're there, the soldiers on the front line have a second life."

Morale, resilience, and sustained combat capability will all be significantly improved.

You are the key to ensuring the defenses don't break down.

Lu Chen put down his pen and stood up straight.

He understood that he had benefited from the protection and resources provided by the state.

They received the recognition and gifts of these heroic predecessors.

Therefore, he should also stand up when the country needs him.

"I'll go."

Lu Chen's voice was not loud, but it was unusually firm.

Tie Shanhe patted him on the shoulder, as if to say something, but in the end he just sighed heavily:

"Good boy! Be careful!"

Shi Qianjun nodded as well:

"Be careful. Your safety is just as important."

Zhu Suqing, Feng Qingyang, Old Li, and others also gathered around, offering their advice in a cacophony of words.

They stuffed all sorts of life-saving pills, talismans, and disposable items into his hands.

"Xiao Lu, take this 'substitute puppet'. It can block a fatal attack in a critical moment!"

"Grandson, this 'Berserk Potion' will increase your strength by 30% for a short time!"

"Lu Chen, this 'Concealment Cloak' can help you hide your presence..."

Lu Chen accepted them one by one, a warm feeling welling up in his heart.

He knew that going to the front lines would be fraught with danger.

But with the love and preparation of these grandparents,

With his incredible resurrection ability, he might just be able to create a miracle.

Looking at Lu Chen, who was surrounded by the crowd, Leng Shuang's cold eyes flashed with a faint hint of approval.

"Get ready, we'll be leaving in an hour."
