A grayish-green miasma lingers in the air year-round.

Ordinary people cannot stay for more than a few days; at best, they will experience fever and vomiting, and at worst, they will lose consciousness or even die.

But for those secretive and ruthless Japanese, this place, which no one dares to enter and which even border patrol police avoid, has become the most ideal hiding place.

For this reason, they are very likely to have built their secret laboratory deep inside the mountain.

All those poisonous vines, poisonous insects, and poisonous plants can be sourced locally.

It is both discreet and efficient, and can greatly reduce transportation risks, saving time and effort.

Then I thought of the strange poison that the old lady had.

Especially the Worry-Free Vine; Su Qingzhi's heart sank suddenly.

This thing only grows on wild hillsides all over the world; no living specimens have ever been found anywhere else.

Its juice is colorless and odorless, yet it can remain dormant in the human body for months.

Ultimately, this leads to nerve paralysis, organ failure, and death in a state resembling sleep.

And now, it has appeared on an ordinary elderly person in the country.

There is only one explanation.

That laboratory not only exists, but it has already begun to operate.

Su Qingzhi had a basic understanding of the situation.

Japan's experimental base is most likely hidden deep in these mountains and forests.

This area is rugged and sparsely populated, shrouded in thick fog year-round, and is almost impossible to find clearly marked on a map.

In addition, there are many rumors circulating among the local people about "shadows appearing" and "strange noises at night".

"We'll set off as soon as we finish offering incense to Grandpa and Mom and Dad."

Su Qingzhi spoke up.

Her loved ones had passed away many years ago, but she had never been able to pay her respects in person. Now she has finally returned to her homeland.

This stick of incense is both a remembrance and a farewell.

From then on, she would embark on an even more perilous path.

Shen Zhiyu was still somewhat worried.

"Why don't you stay in Hong City and wait for me? I'll take some men up there."

He frowned slightly, his gaze fixed on Su Qingzhi's face.

That mountainous area not only has complex terrain, but also has unknown armed forces entrenched there.

The slightest mistake could mean a near-death experience.

He didn't want her to be in such a dangerous situation.

Hongshi is the city on the far side of Yunnan Province, nestled against wild hillsides.

This city is located on the border, surrounded by mountains on three sides and bordering a neighboring country on the other.

It has been a strategic location fought over by military strategists since ancient times.

The streets are narrow and the houses are old.

The air was always filled with a damp smell mixed with the stench of decaying vegetation.

Wild hillsides, on the other hand, are a primeval forest stretching for hundreds of miles.

The area is densely vegetated and teeming with poisonous insects, so even ordinary hunters dare not venture too far in.

Su Qingzhi shook her head.

"I can do it, there's no need to hide."

She wants to uncover the truth herself, even at any cost.

Shen Zhiyu knows her too well; once she's made up her mind about something, nothing can change it.

Su Qingzhi has always been this kind of person since she was a child.

She appears gentle on the surface, but is actually as stubborn as a rock at heart.

He made a silent vow in his heart.

As long as he has a breath left, he will never let anyone hurt her in the slightest.

Even if there were mountains of knives and seas of fire, or a hail of bullets ahead, he had to shield her from all danger.

The two stayed in Jiangcheng for three days to pay respects to their relatives.

After confirming that no one was following them, they boarded the train bound for Yunnan Province.

Upon arriving in Kunming, we changed vehicles and headed south towards Hongshi.

The Spring City has a pleasant climate, with spring-like weather all year round. Flowers bloom along the streets, and pedestrians stroll leisurely.

After boarding the southbound green train, the scenery outside the window gradually changed from the city to hills, and then to continuous green mountains.

The carriage was filled with the smells of instant noodles, sweat, and tobacco.

But they didn't care at all, focusing only on observing whether any suspicious people appeared along the way.

After getting off the bus, Shen Zhiyu led her through the streets and alleys, finally into an inconspicuous house.

This is an old residential building hidden behind a vegetable market.

The exterior walls are mottled, and the stairs creak.

They changed directions several times along the way, and even deliberately wandered into alleys to linger for a while.

Only after confirming that everything was absolutely safe did Shen Zhiyu begin the rhythm of three long and two short rings.

Pushing open the door, I found eight people already standing inside.

The room was small and simply furnished, with several folding tables pushed together.

Several yellowed maps and blurry photos were pasted on the wall.

The dim light shone on everyone's faces.

These people were all tall and straight with sharp eyes.

"Did you bring your wife on vacation?"

A man with a buzz cut grinned, revealing a scar on his face; he looked to be in his early thirties.

Although his tone was teasing, his eyes quickly swept over Su Qingzhi.

Without saying a word, Shen Zhiyu raised his hand and threw a punch.

The opponent nimbly dodged and retaliated with a backhand.

The two exchanged blows for several rounds before stopping.

The man with the buzz cut reacted extremely quickly, parried accurately, and landed steadily.

After a few moves, the two stepped back and laughed at the same time.

This kind of competition is a recognition of each other's strength.

“Sister-in-law, that’s the leader of the Lone Wolf team. Everyone calls him Lone Wolf.”

A short young man leaned close to Su Qingzhi's ear and whispered something.

He was not tall, wore loose camouflage clothing, and still had a somewhat childish look on his face.

But with agile movements and standard posture, he is a special forces soldier who has received rigorous training.

Su Qingzhi remembered him; the last time she returned to Yunjing from Lan City, he had secretly followed her, hiding in the crowd.

The station was crowded that day, and most people were in a hurry.

Only this young man was about ten meters behind her.

Seeing each other again now is definitely not a coincidence.
