Wang Lan asked, looking completely bewildered, "A lump of iron?"

A row of black lines immediately appeared on Old Zhang's smiling face...

“They’re bullets!” he explained. “They’re weapons fired from guns. Since we found bullet casings, it means that the Final Fortress fired shots in this area, which means that someone from them really came out!”

Wang Lan took the bullet casing and saw that it was only the size of a finger, small and exquisite. It was hard to imagine how this thing could become a legendary killing weapon.

However, Old Zhang's words didn't seem like a lie. If that's the case, it means that someone has indeed come forward at the final fortress, and it's somewhere in this market.

Wang Lan said, "Keep searching and see if there are any more footprints nearby. I estimate that these bloody footprints most likely belong to the people inside the fortress. We have to find them no matter what!"

Old Zhang and the fat man nodded repeatedly.

But Sun Muchen said from a short distance ahead, "Brother, there are still bloody footprints here!"

It turned out that while the others were examining the bullet casings, she had already begun searching for bloody footprints nearby.

Upon hearing this, the group quickly ran over.

There was another bloody footprint in the spot Sun Muchen was pointing to, but compared to the footprints found before, this one was unusually irregular, as if it had been made by someone who had twisted their ankle.

However, the two bloody footprints they found pointed them in the right direction.

The group walked quickly forward.

As the bloodstains decreased, more and more footprints appeared on the ground, but they became increasingly irregular, with some footprints being only half-finished.

Finally, the group stopped in front of a house whose door was no longer there.

Wang Lan stepped forward and looked into the room.

The room was found to be empty, with some furniture lying haphazardly on the floor, but in one corner of the room, the entrance to a tunnel could be seen.

The identity of the owner of this house is unknown, but it is not uncommon for people in the market to dig a hole in their house to hide in during the long night and avoid being discovered.

“You three wait here for me,” Wang Lan said to the group. “I’m going down into the cave to see if I can find anything.”

The group nodded.

Just as Wang Lan took off his backpack and rummaged through his belongings, trying to take out his headlamp and night vision goggles, a voice appeared in their ears.

"Hey! Don't rush!"

As the voices were being spoken, several figures jumped out from behind the house and onto the roof, standing beside Wang Lan and the others.

It was the group led by Lu Ren.

Lu Ren looked at the group, then his gaze fell on Wang Lan. He smiled and said, "We're a team. If we have anything good, we'll share it half when we meet."
