National Survival: I Supported the Dragon Nation by Hunting Dinosaurs

"Start the roulette."

Zhang Li had a sudden thought.

A familiar virtual interface appeared, and a huge roulette wheel slowly rotated, eventually settling on four sectors that were flashing with different lights.

This time, I was incredibly lucky.

There are no basic attribute skills; it's all practical, action-oriented stuff.

[1. Master Architect: Proficient in the site selection and construction of various bunkers, fortresses, and defensive works. Grants the host a top-tier understanding of civil engineering.]

2. Hearing Enhancement: Optimizes the auditory frequency range, enabling the capture of infrasound and ultrasound, increasing hearing range by 300%.

3. Trap Master: Proficient in the creation and placement of various lethal traps, including but not limited to booby traps, trigger-activated explosive containers, piercing traps, and large-scale animal trap arrays.

[4. Enhanced Endurance: Physical and mental energy recovery speed increased by 50%, energy consumption reduced by 50%.]

Zhang Li squinted, his gaze quickly sweeping over the four options.

Endurance enhancement is a panacea, and hearing enhancement combined with Omniscient Eye is practically a human radar.

But his gaze was fixed on the first and third items.

Defense construction.

Trap making.

"The seventeen-nation coalition is assembling. Although they haven't found my coordinates yet, it's only a matter of time."

Zhang Li was making plans in his mind.

Although the cave is now hidden, it is essentially just a natural cave.

Once surrounded, even if he had three heads and six arms, he would be worn down to death.

He needs a base.

An impregnable war fortress, fraught with danger.

"Since we're going to fight a positional war, these two skills are indispensable."

Zhang Li took a deep breath. "System, start operating!"

The cursor started spinning wildly.

Zhang Li's eyes were fixed on the two options.

The cursor slowed down, gliding over the yellow stamina boost, then shakily crossed the green auditory boost, and finally...

The pointer was firmly fixed on the red sector.

[Congratulations, host! You have acquired the skill: Trap Master!]

"good!"

Zhang Li clenched his fist.

However, the surprises weren't over yet.

Just as the rewards were being distributed, a golden notification popped up on the system panel.

[Host detected triggering of A-level or higher scores multiple times consecutively; hidden system benefits activated!]

[Skill lock function enabled!]

[Note: The host can "lock" one remaining skill on the roulette wheel. The next time the wheel is spun, that skill will be guaranteed to appear, and the odds of winning will be greatly increased!]

Zhang Li's lips curled up slightly for a fleeting moment.

This damn system has finally learned to behave.

This is equivalent to giving him a "safety net" mechanism.

The roulette wheel was originally supposed to randomly refresh skills, but who knows what kind of junk it will spawn next time.

But with this feature, he can access the skills he urgently needs.

Without any hesitation.

"System, lock onto 'Defense Repair Master'!"

[Successfully locked! This skill will be retained the next time the roulette wheel opens.]

Zhang Li exhaled a breath of stale air.

The traps were set, and the defensive fortifications were also "pre-ordered".

As long as he kills one more dinosaur, no matter how low his score is, as long as he triggers the roulette wheel, he can get his hands on the entire knowledge base of civil engineering.

At that time, in conjunction with the upcoming support from the Dragon Kingdom...

boom--!

A massive flow of information brutally floods the brain.

From the most primitive bamboo stake traps and rockfall traps, to the excrement stakes and simple pressure-activated landmines used during the Vietnam War, and then to the directional explosive booby traps used in modern special operations...

Zhang Li closed his eyes and took a full three minutes to process the information.

When he opened his eyes again, his gaze as he looked at the surrounding jungle had changed.

He knew exactly which tree was suitable for making suspension cables, which plot of land was suitable for burying detonators, and which bushes were suitable for setting up tripwires...

"We have the knowledge, but the materials are a big problem."

Zhang Li frowned slightly.

Ordinary physical traps might be enough to deal with humans, but they are not enough to deal with tough-skinned dinosaurs or enemies equipped with modern weapons.

He needs explosives.

Damn it.

He searched for half a day in the sweltering heat by the salt lake, but couldn't even find a trace of nitrate mines.

Without potassium nitrate, there would be no gunpowder.

"Do we really have to use that method?"

Zhang Li's gaze involuntarily drifted to the edge of the distant salt lake.

There, the enormous Mamenchisaurus had just finished eating.

The massive beast, weighing tens of tons, slowly raised its tail, and a pile of excrement fell from the sky, landing on the ground steaming hot.

Zhang Li glanced at the steaming "mountain" of food and felt a wave of nausea wash over him.

This is not just a disgusting issue.

"Fermentation takes time, even in this high-temperature, high-microbial environment, it takes at least ten days to half a month."

Zhang Li shook his head. "Besides, my storage space is already full."

The carcass of the sub-adult Triceratops, along with a dozen or so plump prehistoric lungfish, had already filled his personal space to the brim.

Why should he throw away perfectly good meat to fill a pile of dinosaur poop?

Zhang Li decisively abandoned this smelly idea, saying, "The matter of saltpeter needs to be considered more carefully."

The most urgent task is to return to defense.

Moreover, they must have another meal on the way back.

"I want that 'Defense Repair Master'."

Zhang Li glanced at the sky; the sun was already beginning to set.

He needs to trigger the next wheel as soon as possible to get the locked skill.

Only by fortifying the camp into a fortress could he have the confidence to face the approaching storm.

Zhang Li activates [Optical Adaptive Camouflage].

His figure twisted in the air, instantly blending into the surrounding withered yellow rock background.

[The All-Seeing Eye is activated.]

Every rustling sound within a 500-meter radius is clearly visible...

They moved quickly, selecting their prey as they went.

Suddenly, he stopped in his tracks.

My gaze passed through layers of ferns and settled on something three hundred meters away.

[Two humans: Extremely exhausted, dehydrated.]

【Golden-winged Birdsaurus (four heads): Late Cretaceous, medium-sized theropod, about 2-3m in length and about 50kg in weight. Extremely intelligent, skilled in team hunting, usually appearing as a scout companion to the apex predator "Tarborodinia".

They were responsible for driving prey to open areas for the king to enjoy, in exchange for leftovers.

Two disheveled figures were staggering and running wildly.

The man running behind was holding a standard military knife, and his body had several cuts from sharp plants.

Even as she fled for her life, the woman in front displayed astonishing explosive power with her long legs.

Her face was deathly pale, and her breathing was rapid...

Zhang Li's brow twitched.

He recognized the woman; she was Li Yue, the star forward for the Chinese women's basketball team.

"Li Yue?"

As for the man, judging from his tactical movements while protecting the woman, he should also be a player from China.

At this moment, the situation of Li Yue and Wang Qiang had also been noticed in the Dragon Kingdom's live broadcast room.

"Holy crap! Qiang Ge and Yue Yue were attacked by dinosaurs on their way to meet Li Shen!"

"What's that dinosaur in the back? It looks like an ostrich, but those claws are terrifying!"

Academician Ma stared intently at the screen, his voice trembling.

"This resembles a golden-winged bird-dragon, and its attack power is very strong! Wang Qiang and his companion only have melee weapons... I'm afraid..."

Just then, expert Xu, who was staring intently at Zhang Li's split screen, suddenly interrupted Academician Ma's words.

"Perhaps, there's still a chance!"
