Mo Feng immediately called Li Zhanting, whose handsome face turned cold and stern the moment he answered the phone.

"What? It could be the basement of the main house?"

On the other end of the phone, Mo Feng said with certainty, "Yes, Master Ting! The design drawings found on Liu Ying's computer are also for ground design. These design drawings are only six or seven years old, so it should have started after Gui Hai infiltrated the Li family!"

A cold glint flashed in Li Zhanting's eyes as he suddenly remembered something.

Five years ago, one day, his grandfather suddenly mentioned to him that he wanted to build an underground parking lot, so he sent people to invite a lot of professional workers.

However, Li Zhanting had many matters concerning the group, and the construction of the underground parking lot was not a very large project, so he did not handle it personally and instead handed it over to his grandfather.

However, he later seemed to hear that the people his grandfather had invited were all famous foreign designers, and that the project was huge, with all the internal construction information kept secret. Li Zhanting forgot about this because he was too busy with the group's affairs.

But now that I think about it carefully, could the person who made the suggestion to him five years ago already be Guihai?

If that's really the case, then they weren't really planning to build an underground parking lot in the first place; it must have been something else underground!

Li Zhanting immediately made a decision and raised his voice, saying, "Immediately conduct a survey of the area beneath the main residence of the Li family."

"Yes, Master Ting! I'll take care of it right away!"

Mo Feng quickly led his men to survey the area, and various sophisticated instruments were activated around the Li family's main residence.

But soon, the final conclusion surprised Li Zhanting greatly!

"What is this?" Li Zhanting suddenly stood up from his seat, staring at the documents Mo Feng had submitted, his handsome face cold and stern.

According to the survey data, the entire main residence of the Li family is hollow underneath, and it is filled with steel and special materials. Judging from the shape of the survey, it looks like a huge underground palace!

"Brother Ting! This organization is just too lawless!" Mo Feng clenched his fists tightly and said through gritted teeth.

This organization not only switched the Li family members, but also extended its reach into the Li family's underground territory.

The Li family occupies a vast area with countless people coming and going. It's hard to imagine how they managed to build an underground fortress here without being noticed by everyone. The technical difficulty alone is probably beyond the reach of most people.

Li Zhanting's sharp eyes flashed with coldness: "Immediately gather the forces of the Dark Night Alliance and secretly encircle and annihilate them!"

"Yes, Master Ting! We'll get ready right away!"

Several tens of minutes later, the Nightfall Alliance forces quickly gathered in a large force around the Li family's residence.

Each member carried sophisticated instruments and followed the design drawings found by Mo Feng to locate the entrance.

This is a huge artificial mountain in the back mountain park. Press the button hidden at the bottom of the artificial mountain, and the artificial mountain will slowly open, revealing a winding and bottomless staircase leading underground.

"Master Ting, we've found the location!"

Li Zhanting quickly extinguished the torch in his hand and ordered his men to secretly infiltrate: "Stay close and proceed according to plan!"

The entire group ventured into the underground area hidden deep within the Li family's main residence. The members of the Dark Night Alliance split into several groups and entered from different entrances, forming an encirclement and slowly invading the underground.

Anyone who enters the underground territory will be monitored by the Dark Moon Organization's surveillance system.

While secretly infiltrating, Li Zhanting's fingers rapidly tapped on the laptop keyboard. After successfully receiving the account and password from Mo Feng, he silently hacked into all the internal systems of the underground prison.

As he watched the word "success" appear on the screen, a beautiful smile curved Li Zhanting's lips...

He had long heard of the infamous reputation of underground prisons.

Rumor has it that a mysterious organization once arranged for countless top designers and architects from around the world to build the world's most challenging underground prison.

The entire underground prison is located in an extremely secluded area, and it is never exposed to the sun. The surrounding area for dozens of miles is completely enclosed by thick iron walls, and the interior is filled with countless traps and mechanisms, making the entire underground prison an impregnable fortress.

But Li Zhanting never expected that this underground prison was hidden right under the Li family's land!

But tonight... he's going to give the Dark Moon Organization an unforgettable super gift package!

Meanwhile, inside the underground prison.

The control room is the central brain of the entire underground prison.

All the prison's traps, surveillance systems, and even the surveillance cameras that monitor the movement of people underground are controlled from here.

The leaders of the underground prison were drunk and indulging in pleasure with beautiful women, completely unaware that danger was quietly approaching.

"Little sister, you sit at the bow of the boat, while little brother walks on the shore, lovingly swaying on the tow rope... Little beauty, come and have a drink!"

The brothers were all drunk. "Big brother, you should drink less. If you drink too much, we might get dragged out by the boss to be questioned again. We can't afford to take that kind of responsibility. What if the Li family finds out about this place?"

The leaders, their faces flushed and reeking of alcohol, shouted, "This underground prison of ours is a godforsaken place, not even a ghost would come here! Besides, who would have thought that such a huge underground prison was hidden beneath the Li family's territory in the capital? Li Zhanting must be out of his mind to come here, hahaha..."

Upon hearing this, the brothers immediately perked up, "Big Brother is right! I was overthinking it, let's keep drinking!"

The control room reeked of alcohol. Just then, a leader, who was quite drunk, seemed to notice a notification on the control room screen and was immediately jolted awake.
