For the first time, Guan Tianxiang felt the incomparably hot feeling, and at this moment, he felt as if he was next to a furnace, waiting for the baked steel.

The temperature on the ground floor is believed to be much higher than that on the upper floors, and it is conservatively estimated that there are more than 30 degrees Celsius, but in fact it may be more than 40 degrees, which feels like a big melting pot burning on the ground floor.

Why is this so? Could it be that there is a fire in the lobby?

They don't know yet, because they haven't been able to enter this building, this building's original Exit.

However, if a fire breaks out in the lobby, how does it not spread to other floors? It's a weird scene......

Ah Mao kept trying to knock open the smoke door, and his whole body kept rushing towards the indestructible iron door, but in exchange for a continuous collision sound, echoing in the hollow back staircase.

"Damn, why the fuck can't you push it away?" Ah Mao exhausted all his strength and leaned against the wall breathlessly.

Guan Tianxiang stared at the glass window in the center of the smoke-proof door, which was originally used to peek at the situation. The glass window was in the shape of a square, roughly estimated to be 10 centimeters by 10 centimeters, with smaller squares separated by lines.

Guan Tianxiang snatched Ah Mao's mobile phone, and saw that the mobile phone only had 3% of the electricity, he smiled bitterly, if Ah Mao was lucky enough to bring a portable charger, he would have consumed even the only power he had in the morning.

Then, as Mei Tao said, go back to the Stone Age.

The words "No Signal" are still displayed in the upper left corner of the phone, and the telecommunication network here has been deliberately cut off. Or are they simply in a space where there is no signal?

"This is not the Bay Area." Aunt Wang's words suddenly echoed loudly in Guan Tianxiang's mind, and every word was deeply imprinted in his messy thoughts.

Could it be that the space they are in is no longer the familiar Xiangcheng? What kind of picture is hidden in the world outside the smoke-proof door? Do the familiar alleys and dense high-rise buildings still exist outside the door?

Guan Tianxiang shone the light of Ah Mao's mobile phone into the glass window, but he couldn't see the environment.

Under normal circumstances, through the glass window, you should be looking at the lobby on the ground level, and it is the seat that happens to witness the administrator.

However, at this moment, on the other side of the glass, it was pitch black, and Guan Tianxiang couldn't even see the vague outline, as if something blocked the door.

If you tell Guan Tianxiang at this moment that the other side of the smoke-proof door is not the so-called ground elevator lobby at all, but the void and dark chaos, Guan Tianxiang will not be stunned.

It feels like the whole building, leaving the bustle and noise of the Internet teaching crowds, and traveling through time and space to a space that humans can't recognize.

"Fuck, slam the door." Ah Mao was furious, as if he had exhausted the fuel of calm, raised the dragon slaying knife, and slashed angrily at the smoke-proof door.

With a "bang", Ah Mao was rebounded to the rear, lost his center of gravity and took several steps back, almost falling, but fortunately, the little only man Ah Jian was beside him to help him.

The indestructible smoke-proof door, of course, was not destroyed so easily, and the bloody iron door was only added to a knife mark at the moment.

Mei Tao smiled dryly, staring at the obstacle in front of him.

"Is there anything that can block this door......" Guan Tianxiang muttered.

Smoke doors are designed to prevent the spread of fire in the event of a fire, to keep out toxic fog and to maintain a safe environment behind the staircase. It doesn't have a lock, so it's definitely something else that is blocked on the other side. Maybe it's a hard object weighing a thousand pounds, or it can be several chains.

Yes, it is impossible to lock the smoke door...... Impossible to lock......

Guan Tianxiang glanced at Mei Tao, and he who was chuckling just now became expressionless and silent.

"Wait, what's this?" Elsie pointed to the strange smoke-proof door outside the door, and Guan Tianxiang subconsciously used the light to shine at the location she was pointing at, and at the same time beware of her.

The fire alarm rang suddenly, and they ignored it.

Ai Xi pointed to the position next to the blood word, Guan Tianxiang carefully observed, what are those round holes......

At first, Guan Tianxiang thought that those round holes were smudges or deliberately painted by others, but after looking closely, he could still see what those Confucius looked like.

It looked like bullet holes, more than a dozen dense bullet holes, deeply imprinted on the gray smoke-proof door. There were a lot of blood stains on the bottom of the door and on the ground, and it is speculated that it was most likely left behind by the person who was shot. Guan Tianxiang suddenly felt that things had risen to a more serious level: the conflict here not only appeared ancient weapons such as swords, but also firearms with incomparable lethality.

How could there be these firearms in a civilian-inhabited building? Isn't the Bay Area forbidden to have any firearms to civilians other than police and military personnel?

Who is the man with the gun? Why did he shoot? Is he Brother Ling's man? What kind of enemy is he going to shoot? Guan Tianxiang hurriedly relied on his only analytical ability to deduce the whole thing by himself.

The gunman probably fired in the direction of the door from their position, so that the bullet hole was left in this position. Alternatively, if the shooter is in the underground lobby and shoots at the door that has been pushed open, the same effect will be achieved.

Guan Tianxiang believes that the person who was shot later died of excessive blood loss. Usually the person who writes these blood words must know that he has lost too much blood and his life is short, so he will use his own blood to write with his own blood. Or, a perverted bloodthirsty murderer who shoots and kills, smears the door with the blood of the dead.

And the body of the deceased, after death, must have been removed by others, which led to the devastation that made the bones stand on end at this moment.

Guan Tianxiang stared at the metal door with his hair standing on end, and the others seemed to be at a loss, standing still, but at a loss.

At this moment, they can only explore and analyze the mysterious blood words on the iron door.

Guan Tianxiang used the light of his mobile phone to illuminate the blood words that occupied half of the door, two English words that were simply renamed, but they looked particularly strange here.

"Bottom Ierp......" Guan Tianxiang looked at each bold blood word one by one to make sure they didn't understand it wrong. Guan Tianxiang can conclude that no matter how bad the handwriting is, what he is looking at must be the "bottom ierp".

"Bottom ......" Ah Mao suddenly held his chin in his hand, frowned, thoughtful.

Perhaps because of the lack of Wenqing's temperament, Guan Tianxiang squinted at Ah Mao, who was thinking calmly, and always felt a little weird, especially when Mei Tao, who had repeatedly made high views, was silent.

The restless silence returned to the back staircase, and everyone held their breath, anxiously waiting for Ah Mao to finish speaking. Ah Jian remained silent and stood at the bottom of the back staircase, silently waiting for their further analysis.
