The towering main building of the North Ring Tower stands majestically in front of everyone, this glorious building that once represented the highest scientific and technological achievements of mankind and the future of civilization has now been mottled and decayed, the cement exterior wall is full of potholes peeling marks and cracks caused by wind and sun, the once bright paint has basically faded into a dirty yellow-brown, and a large area of wall skin has fallen off, forming a disgusting layer of soft soil around the ring tower. But its main body is still sturdy, and the reinforced steel skeleton supports the old tower well, and it seems that there is no need to worry about collapse.

"There's no sign of the nano-swarm," Nolan looked up at the almost straight wall, "and it's not much different from the last time I was here, it looks like no other adventurer has been here in a year." ”

Hao Ren was curious about what Nolan was doing in this place a year ago, but it didn't seem like the time to ask about it. Ulanov led the group in search of the entrance to the tower, and after rounding a circular outer wall, they saw a shattered gate, which, judging by the marks around the gate, had been blown open.

"More than one group of people have been here in the past sixty-five years, and the attraction of pre-war technology is not new," Nolan said to the mercenaries who came here for the first time, "Most of the fools who want to dig up treasures from here have not come back alive, so if you still want to go back alive, listen to the command, and don't mess with things you don't know." ”

"Isn't there no nano swarm?" Hao Ren asked casually.

"Do you think the nano swarm is the only danger here?" Nolan raised his gun, "We didn't bring guns to deal with nanomachines. There are guards in this place, which were originally used to guard the underground containers, and they are all things that have a theoretical lifespan of 100 years. God knows what their program has broken now. ”

Ulanov nodded slightly in affirmation of Nolan's statement.

Hao Ren looked down at the weapon in his hand, which was a light assault rifle. The gun body is projected with a laser to show the remaining ammunition level, the current user, the status of the machine, and other characteristics, as well as a gray fox marking. This weapon was given to him by Nolan. Although Hao Ren has not yet joined the gang, Nolan can't let his companions go into battle empty-handed.

Before entering the building, Ulanov touched Hao Ren's arm: "How is your marksmanship?" ”

Hao Ren replied vaguely: "It's similar to fist and foot kung fu." ”

"Okay, you and I will walk together, and we will open the way for the boys in front and behind."

The mercenaries covered the two researchers of the White River Chamber of Commerce and cautiously walked through the door, revealing the abandoned and collapsed inner corridor. Paint and cement shards scattered from the walls, rust on the roof, and an eerie atmosphere permeated the decades-old building, which some mercenaries swallowed nervously. The grunt was clearly audible in the silent hallway.

There was silence all around, except for the careful footsteps and breathing of the crowd. Nolan walked at the front of the line, and Hao Ren and Ulanov guarded the surroundings from left to right. The further forward the corridor became, the darker it became, the limited windows on the outer wall of the ring tower could no longer provide sufficient light to the depths of the building, and the few mercenaries who had not undergone visual modifications put on night vision devices, and in the pale green night vision vision, the strange Cheng dù of this place was even worse.

Hao Ren looked at the people around him, he could still see things clearly in this place, but considering his status as a "natural person". He still wears night vision goggles like everyone else.

"Do you know where you're going?" Nolan stopped slightly, turned his head sideways and asked the researcher of the White River Chamber of Commerce not far behind him.

"The main control room, the computer number one control terminal," the emaciated researcher replied calmly. Although he was only a civilian, he was as calm as the soldiers in this environment, which made Hao Ren couldn't help but look at this person more.

When you hear the words "main control room". Ulanov's breath couldn't help choking, and he took the initiative to step forward: "I know the shortest route. ”

Nolan nodded: "Okay." You lead the way. ”

The team continued to walk deeper into the building and found a spiral staircase that spiraled upwards. At the top of the stairs is the location of the main control room. Hao Ren and Ulanov went to check if the stairs were still strong, but halfway through he suddenly saw a skeleton lying on the stairs.

Ulanov immediately crouched down to check the condition of the skeleton, and judged the identity of the man from the fragments of the other party's clothes: "...... It was a staff member in the ring tower, who seemed to have fallen from above and died. ”

The nano-swarm did not attack the Northland Ring Tower after it got out of control, so the people in this building survived longer than the others in the disaster, but their fate was not much better than that of those who were dissolved outside. In that disaster, the building was sealed off as a complete island, with no supplies, no rescue, no hope - they were trapped alive in this place, and as researchers and controllers of nanomachines, they also knew that no one could break through the wreaking havoc outside to save them. No one knows how the people in the Ring Tower spent the last days of their lives, and for the twenty years since the catastrophe began, the situation inside the Northland Ruins was completely unknown to the world. When a group of desperate troops finally broke into the place with huge casualties, they found only a single corpse.

According to the soldiers who came back alive, the people in the ring tower had a variety of causes of death, most of them died of starvation, a few committed suicide, and the rest were basically killed in a fight, perhaps to grab the last of the food, and there was a riot here. There are also many more gruesome accounts that have been handed down, such as the sighting of kitchen utensils containing human bones in the ruined kitchen of the Ring Tower, and the mass of mutilated corpses in a certain room......

Each one is a tingling on the scalp.

Hao Ren looked down at Ulanov, who was examining the bones, he didn't know if this man recalled those dark rumors about the North Earth Ring Tower at this moment, in order not to delay time, he patted the other party's shoulder: "Let's go, the people behind are waiting." ”

Only then did Ulanov slowly stand up.

The crowd leads up the guò staircase to the second floor, and after bypassing a narrow passage, a large wide corridor appears in front of them. Ulanov pointed to a gate not far away: "That's the control room you're looking for." ”

"The door turned out to be intact...... Nolan looked at the door with some surprise, "I thought the guy who came here before had smashed every door." ”

"There is probably an alarm device connected to the back of this door," a researcher from the White River Chamber of Commerce stepped forward to check the status of the gate, "...... Incredible, the latching device is electrified! The energy in this place has not been cut off yet! ”

Nolan glanced at the researcher with a meaningful look, and it seemed that this man knew a lot about the situation in the ring tower.

Ulanov turned his head to look at the end of the dark corridor, and he seemed to see something that he cared about: "You're busy here, I'll go and take a look." ”

After he said this, he walked straight to the front, and Nolan saw this, and ordered the mercenary beside him: "Carl, you come with him." ”

The tall mercenary Karlmer nodded silently and quickly followed Ulanov's pace, and the figures of the two soon disappeared into the dark end of the corridor.

Hao Ren didn't care too much, he felt that Ulanov should have taken advantage of this time to look for clues about his wife, and it was not good for an outsider to take the initiative to come over to see the excitement. He turned his head and continued to watch as the White River Chamber of Commerce researcher tinkered with the locking device on the door, which was incredibly usable to this day.

And just then, a shrill gunshot suddenly broke the silence inside the building.

Hao Ren instantly looked up at the place where the gunfire came from - that was the direction Ulanov and Karl had left!

Nolan's voice rang out at the same time as the last gunshot fell: "People from the second team, go over and see the situation." ”

Hao Ren didn't know how many teams he was, and he didn't think about it so much, and when Nolan spoke, he had already rushed to the other end of the hallway.

I don't know if it's an illusion, but as he lifted his legs, he suddenly saw the walls of the corridor around him fluctuate like the surface of the water, although it was only a brief moment, but it was extremely interesting. (To be continued......)
