Siheyuan: I, Shazhu, started out as an army and became a general.

Headquarters of the Chinese People's Volunteer Army.

He Yuzhu couldn't stay in bed for more than two days before he was completely unable to continue.

His abnormal regenerative ability, like that of a tiger or wolf, meant that his skin and flesh wounds had already scabbed over; if he lay down any longer, his bones would rust.

At this moment, the headquarters operations room was filled with smoke, resembling a spider's web.

The old marshal was in charge, with several Soviet military advisors beside him, and opposite him were the army commanders of various armies who had just come from the front lines. Each of them had a solemn expression, and the atmosphere was so oppressive that it could be squeezed out of water.

He Yuzhu stood in the corner; as a "special advisor," he was entitled to listen in.

"We must retaliate! Retaliate immediately!"

A blond, blue-eyed Soviet military advisor, Prokov, was tapping a map with a baton, spitting as he spoke.

The translator beside him was sweating profusely as he relayed the information.

"We held Tieling, but so what? The American artillery superiority is still there! The best defense is offense! Large-scale troop incursions! Drive those Americans straight into the sea to feed the fish!"

The old general's brows were furrowed, and he was completely unaware that the cigarette butt in his hand was almost burning his fingers.

"Comrade Prokov, the soldiers have fought to their limit." The old marshal's voice was a little hoarse. "You saw the enemy's Van Fleet ammunition load. Those aren't artillery shells; they're a waterfall of steel. I don't even want to think about the casualties of charging in this rain of fire."

"The cost? War always results in death!" Prokov raised his chin, his face full of arrogance. "What's the point of fighting if you're afraid of sacrifice? Have you forgotten the Bolsheviks' iron will?!"

Upon hearing this, several army commanders clenched their fists and tensed their jaws.

Sacrifice? Damn it, who's afraid of sacrifice!

But what kind of fighting style is this, risking people's lives and running into the line of fire?

"Report."

A clear, cold voice, like an icicle, instantly pierced the frozen air.

Everyone turned their heads in unison.

He Yuzhu walked out from the corner, his face expressionless.

"Who are you? Who gives you the right to speak here?" Proko

The man frowned, as if looking at a buzzing fly.

The old coach waved his hand: "Let him speak. He is He Yuzhu, the tiger who captured Walker."

"tiger"?

Prokov's eyes flickered, his contempt undiminished: "Oh, the one who plays the hero? Go ahead, what do you want to say?"

He Yuzhu walked up to the map, didn't even look at it, and pointed his finger directly at the long battle line.

"Attack will inevitably lead to defeat."

Four words, resounding with conviction.

Prokov immediately exploded: "Who do you think you are, daring to talk about command? Have you even been to Frunze?!"

"Never been."

He Yuzhu turned his head and looked at him as if he were a primitive man who had not fully evolved.

"But I know that in this battle, whoever survives to the end will be the winner."

"Survive?"

"That's right." He Yuzhu picked up a pencil and drew a few circles on the map. "The US military's tactics are simple and brutal, just three steps: artillery bombardment to flatten the hills; air bombardment to plow them up again; and finally, infantry leisurely come up to collect our corpses."

"Our soldiers were hiding in makeshift bunkers, making them easy targets."

"So what we need to do is not to fill this bottomless pit with human lives, but rather—"

He Yuzhu spoke slowly and deliberately.

"Dig a hole!"

"Dig holes?" Prokov laughed in exasperation. "You want us to be groundhogs? We want victory, not to hide underground like cowards!"

"A coward?" He Yuzhu sneered. "That's because your vision is too narrow. You don't understand what the 'Underground Great Wall' is."

As soon as he finished speaking, a system notification rang out crisply in his mind!

[Ding! Host detected at a critical juncture in strategic decision-making!]

[Check-in successful! Location: Operations Room, Headquarters of the Chinese People's Volunteer Army!]

[Rewards: Infrastructure Master Template (Beginner), Advanced Civil Engineering Mastery (Tunnel Defense Specialization), All-Terrain Geological Structure Analysis!]

In a second, his mind went blank!

Countless pieces of knowledge about tunnels, reverse slopes, anti-artillery bunkers, ventilation and drainage systems, and crossfire networks were forcibly instilled into his mind, instantly filling it!

He Yuzhu's entire demeanor changed instantly.

Previously, he was a sharp blade drawn from its sheath, its edge fully revealed.

Now, he is a mountain, an immovable and unfathomable majestic mountain!

He picked up a pencil and began to write furiously on the paper.

"This is called a reverse slope tunnel."

"This is a cat-ear hole."

"All fortifications must be protected against seven things: air, artillery, poison, rain, moisture, fire, and cold."

"This is a troop shelter, this is an ammunition depot, all connected by trenches to form a complete underground network!"

He Yuzhu drew and explained at the same time, his voice not loud, but every word carried great weight.

Prokov, who had initially looked disdainful, widened his eyes even further.

The army commanders present even forgot to breathe.

A true expert's skill is immediately apparent!

This isn't just digging a tunnel; this is a complete, three-dimensional underground fortress system that could even withstand a nuclear attack!

"Within these fortifications, even if the enemy blasts the hilltop into the surface of the moon, we will remain unscathed."

"Once the shelling stops, our men emerge from underground, set up machine guns, and kill whoever comes. That's not fighting; that's one-sided slaughter!"

He Yuzhu slammed the pencil down on the table and stared straight at Prokov.

"Comrade Advisor, I admit that an iron will is very important."

He stared at him and said, word by word.

"But willpower is ultimately soft. Add reinforced concrete, and it becomes even harder! Hard enough to crush the enemy's teeth!"

Quiet.

A deathly silence.

After a long while, the old general suddenly slammed his hand on the table and stood up abruptly!

"Excellent! What a magnificent underground Great Wall!"

The old coach's eyes gleamed, as if he had seen the key to turning the tide of battle.

"If the entire army could use these fortifications, casualties could be reduced by at least 70%! 70%!"

Prokov's face turned a deep purplish-red, and he opened his mouth several times, but couldn't utter a single word.

Even someone as stupid as him could see that this system was technically flawless and was practically designed to counter the firepower of the US military!

"This...this is all just theoretical!" Prokov stubbornly tried to save face. "Shangganling is all granite! They could dig this kind of fortification in half a month? Do you think you're a god? Absolutely impossible!"

He Yuzhu smiled.

That smile was full of the confidence and disdain that belonged to the "infrastructure maniac".

There is no such thing as "impossible" when it comes to China's infrastructure prowess!

"impossible?"

He Yuzhu looked at the old general, his voice firm and powerful.

"Sir! Give me an engineer battalion and an infantry company!"

"Let's go to the toughest spot, Shangganling Hill 597.9!"

"Half a month! Just half a month! If this fortification can't withstand the saturation bombing of the US military—"

"I, He Yuzhu, will bring you my head!"

The old general's eyes were like torches, staring intently at He Yuzhu, as if trying to see through his soul.

After a long pause, he roared:

"good!"

"He Yuzhu, listen to my command!"

"I hereby appoint you as the Commander-in-Chief of the Special Engineering Command. Proceed to Hill 597.9 immediately!"

"I want to see if you, this tiger, can break the teeth of the American soldiers inside the rocks!"

"yes!"

He Yuzhu saluted sharply, turned around, and strode away.

Behind him, Prokov stared blankly at the retreating figure, muttering to himself, "Madmen...are all these Chinese...crazy?"
