Lin Fan fell silent.

He had discussed with the National Chair the matter of humanity having only fifteen years left before total extinction. The National Chair believed it was best not to disclose this, lest unnecessary chaos ensue.

But—

“Gods appeared fifteen years ago, and humanity was annihilated.”

“Great Xia held out to the end, but ultimately…” Lin Fan continued, his tone heavy.

For a moment, the atmosphere in the Supreme Command Center’s office was unbearably tense.

“Annihilation…”

“Fifteen years, all wiped out?”

“Six billion souls, so much brilliant culture…”

“Our mighty Great Xia, exerting all its strength until the very last, and even then, we could not…”

Even Bai Zhan, the Sichuan Military District Commander, couldn’t help but rub his face and mutter, “So this… is the future?”

The previously spirited crowd from the meeting now wore complex expressions.

They had heard about their own deaths in the future, and did not hesitate.

Yet now, hearing of Great Xia’s fate fifteen years from now, every face was weighed down with gravity.

Lin Fan looked at them and spoke quietly, “Gentlemen, by age, you are all my uncles, elders, some even grandfathers.”

“That was history I experienced firsthand, and it is a future about to unfold.”

“But, the future is not set in stone!”

“I have returned this time to change the future—to rewrite history!”

Bai Zhan nodded, clenching his fist. “Exactly! It hasn’t happened yet. As long as Great Xia is prepared, what does it matter?”

“We will overturn the future!”

“With the combined might of our nation, Great Xia will change its fate!”

“From today, the gods will halt at Great Xia’s border!”

In an instant, flames ignited in everyone’s eyes.

The future?

A predetermined fate?

Great Xia never feared adversity!

If you seek to invade Great Xia—even gods shall fall before us!

“Let’s turn to specifics,” Lin Fan said, seeing the renewed resolve in their faces. “The upcoming recruitment falls to you: Sichuan is responsible for five million, Shandong for five million, the three northeastern provinces for ten million, the rest…”

“In total, fifty million. Any objections?”

The military commanders replied in deep voices, “No objections!”

“We guarantee the task will be completed!”

“Actually, I could take on more. My son’s generation of youth—they’re tougher than we ever were,” Bai Zhan said with a broad grin.

“Good! If you can recruit more, do so,” Lin Fan continued. “Alongside recruitment, conduct genetic activity tests. Anyone scoring above eighty percent, send me their names—they join the Godslayer Army! Recruitment must be complete within a week, and the Godslayer Army must exceed one hundred members!”

At this, Lin Fan glanced at Chen Yan. The Godslayer Demon-Slaying Technique in his mind had been developed by this elder himself!

“One week—no problem!”

“I’ll give the order now! From today, Sichuan will open five thousand recruitment centers!”

“Time is tight, but we will complete the mission!”

The military district leaders spoke through gritted teeth.

“Good, gentlemen, get to preparations,” Lin Fan smiled. “Also, regarding the Steel Great Wall project, I ask for your assistance.”

“Count on us!”

With heroic bearing, the military commanders strode out, their bodies suffused with battle spirit.

“Deputy Commander Chen Yan,” Lin Fan turned to the elder at his side, “Next, I need you to oversee the Steel Great Wall project.”

With that, Lin Fan produced a simple blueprint from his breast pocket. It depicted a hundred-meter-long wall, detailing the foundation, interior structure, and every material, all meticulously marked in pencil.

He had rushed to create it the night before.

Though Lin Fan had not been in charge of research in his past life, he was Great Xia’s War God, personally commanding many constructions, even participating directly in the building of the Steel Great Wall as a sergeant.

He remembered the structure well enough.

“This is…” Chen Yan stared in awe at the blueprint. “The Steel Great Wall structure? You drew this?”

“It was your team at the research institute who developed it in the future,” Lin Fan dared not claim credit, “This is the crystallization of Great Xia’s wisdom.”

“Of course, this is only a rough sketch. Some details may be off. You’ll need to correct them with your team.”

Chen Yan stroked the blueprint, his expression ever more stunned.

A wall three hundred meters tall.

Steel supports, concrete poured, a foundation five hundred meters deep!

“Perfect—almost flawless application of mechanics!”

“And this material ratio—using cement, sand, and some recyclable materials for filling, it saves eighty percent of steel!”

“Even the world’s top architects could not devise such a design—truly ingenious!”

“So—this really is the Steel Great Wall, forged by Great Xia of the future?” Chen Yan looked at Lin Fan with a complex gaze.

“Yes.” Lin Fan nodded. “Sadly, we didn’t build it in advance, and in the end, had to patch things up too late.”

“It was you, leading the research institute through sleepless nights, who created these blueprints in just seven days!”

Chen Yan drew a sharp breath. “Seven days!”

He was silent for a long while.

Looking at the blueprint in his hand, Chen Yan suddenly laughed.

“Haha, unknowingly, Great Xia has gained such capability.”

“We once guarded our gates, suffering blows. Now, in seven days, we can design a Steel Great Wall!”

“Now, I suddenly feel—if the gods make us their enemy, it may be their greatest mistake!”

Once, Great Xia was the epitome of technological backwardness.

History taught Great Xia with painful lessons: fall behind, and you get beaten.

For nearly a century, Great Xia focused on development, quietly growing stronger.

Looking up again—

They found themselves still standing proudly atop the world, their technology surpassing the international elite!

At this moment, holding the preliminary blueprint for the Steel Great Wall, Chen Yan’s aged eyes blurred. How he wished the ancestors could see today’s Great Xia, witness this prosperity!

Watching Chen Yan tremble, Lin Fan suddenly spoke in a deep voice, “You have one week to restore the blueprint fully, including all details. Can you do it?”

Whoosh!

A surge of strength seemed to arise from nowhere in Chen Yan’s elderly frame as he leapt to his feet. A fierce aura emanated from this scientific titan who had never wielded a weapon.

“I’ll have it done in three days!”

The sixty-year-old’s back was straight!

With this general structure as a foundation, he believed just three sleepless nights with his institute team would yield a perfect blueprint for the Steel Great Wall!

Though aged and unable to carry a gun or fight on the battlefield,

His loyalty to Great Xia burned as hot as ever! The blood of Great Xia still boiled within him!

But then, Chen Yan frowned, pencil poised, calculating on the back of the blueprint.

Sweat beaded on his wrinkled brow.

After several minutes, Chen Yan lifted his head, his expression complicated. “It’s just… although this design minimizes steel consumption, even for a preliminary build along two thousand miles of Shandong’s coastline, we’ll need at least eighty million tons of steel.”

“To construct the full three hundred-meter-high Steel Great Wall along the entire coastline, we’d need… two billion tons!”

“How will we solve the steel problem?”
