"Attention, this is Dr. Marcus."

Some old voices echoed in the brightly lit halls.

"Please be quiet as we recall our company motto."

"Obedience breeds discipline."

"Discipline produces unity."

"Togetherness brings strength."

"Power is life!"

"It's broadcasting, there must be someone in the radio room!"

Billy affirmed.

"I know......"

9S's voice came from behind Billy.

"We'll get there later, but before we do, Billy, get out of the way."

"What?"

Billy turned his head to look behind him in surprise, only to find that 9S had somehow pulled out a thick, long cylinder and carried it on his right shoulder, and a rocket was inserted into the cylinder......

‘RPG？！ ’

As soon as this thought came to Billy's mind, he saw 9S suddenly close his left eye and put his right eye behind the bazooka's sight.

"Oh ~ damn it!"

Billy let out a low roar and leaped to the side, covering his ears tightly with his hands as he slammed down on the floor.

“…… Boom-"

After a few seconds, the RPG exploded as several debris flew down on Billy's back.

"Billy, are you alright? I'm telling you to go away, what's the situation with you lying down directly? ”

Hearing 9S's voice, Billy let go of his hands and raised his head, seeing that 9S was standing not far from him with a bazooka without rockets, and the smile on his face had no intention of hiding it.

“…… I'm fine, but please let me know in advance the next time you're doing something like this! ”

Billy lay on the floor and was silent for a moment, then scrambled to his feet, speaking towards 9S with a hint of anger in his tone.

"Well~ Obviously you saw me put my eyes on the sight, and then just lay down, blame me?"

“……”

"Okay, okay, the next time I use an RPG, I'll let you know in advance, okay?"

Seeing Billy's silence, 9S shrugged helplessly and said.

“…… What did you just blow up with an RPG? ”

Billy put on a straight face and changed the subject directly.

"It's just a secret passage."

Billy turned his head to look in the direction of the 9S shot, and sure enough, he saw the entrance to a passageway, right in the middle of the T-shaped staircase, if he remembered correctly, there seemed to be a painting hanging in that place just now, right?

"The key to open this passage requires us to run back and forth in this place a few times, so I just exploded to save trouble."

9S shrugged, dropped the bazooka on the ground, and strode up the T-shaped staircase towards the passage.

I apologize to the people who designed this mechanism!

Just as Billy was looking at 9S with a smile and a smile, 2B and A2 walked directly past him and followed 9S in front of him, watching all three of them walk up, and Billy below also followed.

"Shall we go down now?"

Billy looked at the secret passage in front of him, the walls of this passage looked quite solid, and the RPG from 9S just now only blew up the walls of this passage a little bit after blowing up the secret door.

"No......" 9S looked at the dozens of steps down the passage, and stretched out his right hand behind him: "Below is one of the laboratories in this place, I blew up this place just so that the antitoxin could spread inside." ”

9S retracted his right hand, held a test tube that Billy was familiar with, and threw it directly into the passage.

"Smack~"

The test tube spun rapidly in the air, and in the blink of an eye, it flew to the bottom of the stairs, and after the test tube was shattered, the antitoxin inside also evaporated smoothly into the air.

"Sizzle——!"

A slightly shrill cry came from the bottom of the passage, and with the sound, a black object fell directly onto the floor at the bottom of the passage.

"Is this a spider?"

Billy looked at the giant spider that was dozens of times larger than ordinary spiders, and couldn't help but feel a little furious in his heart, this spider was also infected with the T virus? No, the size of the zombie dogs that attacked him before was very normal.

"yes, didn't I say that the following is Ambrera's lab? It's just some mutated spiders, they won't survive anyway. ”

“…… They? ”

Billy seemed to hear screams coming from below.

"Let's go, go find the guy in the radio room."

9S walked up the stairs to the right of the T-staircase, came directly to a door facing the staircase, raised his right leg, and kicked it out.

"Boom-"

Under the physical fitness of 9S, which is far more than ten times that of ordinary humans, the brown wooden door fell in response, because the back of this wooden door is a corner, so the fallen wooden door was directly against the wall, slowly sliding down.

"Let's go."

9S greeted and disappeared directly around the corner behind the door.

A2 and 2B silently followed, while Billy followed unhurriedly.

"Boom-"

Just as Billy's corpse turned left as he stepped on the wooden door, a familiar sound sounded from the top of the stairs not far ahead.

'RPG again?! What is 9S bombing again? ’

Billy frowned slightly, and walked briskly up the stairs not far in front of him.

When Billy reached the end, 9S found himself dropping a rocket launcher on the ground and reaching behind him with his right hand.

"Really, these two things are really in the way......"

9S looked at the iron door in front of him and complained, there were two knight statues made of steel standing on either side of the iron door, but they didn't look like knights - I saw that the original metallic appearance of the two statues had been painted with a layer of black, and the knight sword that was originally held in his hand had been blown up by 9S's RPG.

9S said that there was no way to do this, who let the knight swords of these two goods cross together, directly blocking the door he was going to blow up, there was no way, so he had to blow it up together.

"Forget it, let's ......"

As soon as 9S's words fell, Billy, who was standing behind him, finally solved the problem that had been bothering him - a circular pattern with a faint glow appeared behind 9S, and 9S's right hand reached directly into the pattern, as if the pattern was the entrance to a pocket. After half a second, 9S's right hand withdrew, along with a long, thick bazooka.

Billy raised his eyebrows, he finally knew where the 9S things were taken out of, and he didn't feel much surprise, after all, 9S took out things out of thin air in front of him many times, and he would have been surprised a long time ago, at most, he sighed in his heart after seeing how 9S took out things, "This ability is really convenient".

"Boom-"

With Billy's knowing expression on his face, 9S aimed at the steel gate and pulled the trigger of the bazooka again......
