That day, on the rooftop, I accidentally stumbled upon two men conversing.

At that time, I was frustrated after investigating the whole morning and finding no useful information.

So, I went up to the rooftop alone to relax and catch my breath.

About half an hour later, two men sneaked onto the rooftop.

They locked the rooftop door and looked around cautiously.

I was small in stature and well-hidden, so they didn't notice me.

From my perspective, I could only see the face of one of the men.

That man was burly and had a fierce expression on his face.

The first sentence he uttered shocked me and made my heart skip a beat.

Furrowing his brow, he questioned the man in front of him:

"You swallowed such a big piece of fat, don't you take 'Darkwood' lightly?"

Hearing the words "Darkwood," my heart pounded with shock.

It was an extremely mysterious tomb-robbing organization.

Above the hidden tombs, dense woods flourished.

Every time they robbed a tomb, they would scatter numerous seeds and nutrients in the tomb-robbing area.

Those tombs were already remote, often located in rural fields.

In just a few months, the seeds would take root and sprout, growing into dense thickets.

The most perfect concealment was to blend in with nature.

It was almost impossible for people to detect what lay beneath this land overrun with weeds.

Beneath it hid a tomb that had already been plundered.

In a few more years, when the grass of the thickets grew into trees.

The roots of those trees would rampage underground, causing secondary damage to the tomb.

The tombs of the Western Han Dynasty's Chengyang Marquis and the Qin Dynasty's Flying Tiger General.

Suffered irreparable losses due to Darkwood.

Furthermore, to reduce risks and evade investigation, they only dealt with foreign buyers.

Over the years, there have been no less than a thousand precious cultural relics scattered overseas because of them.

Although they committed major crimes repeatedly, their actions were secretive and mysterious.

The police tracked them for years but gained nothing.

But who could have imagined:

These illegal tomb-robbing organizations actually had connections with the archaeological institute?

The man with his back turned to me.

His attire, no matter how you looked at it, undoubtedly belonged to someone from the archaeological institute.

No wonder Darkwood always had such timely information.

They could always be one step ahead, robbing the tombs before the institute's excavation and protection.

So, it turns out there's a ghost inside the institute, constantly giving them inside information.
