Drenched in heavy rain, A2 walked briskly to the entrance of the tunnel, pressing his hands directly on the edge of the plank......

"Click~Click~"

“…… 9S, are all the people in your leaves so powerful? ”

Billy looked at A2, who easily dismantled the wooden planks in pieces, and asked 9S next to him in shock.

"Well~A2's combat power is the most powerful among our leaves, and others may be a little worse, but it's not much worse."

9S shrugged his shoulders and explained towards Billy.

"By the way, 7B and 8B, have you received any information from me?"

"Huh?"

Billy looked at the 9S inexplicably, is there anyone else here?

"Roger, what are the orders?"

Two sullen female voices suddenly rang out from behind Billy.

"Who?!"

Billy could feel the owner of these two voices very close to him, and he subconsciously took a few steps forward, and quickly turned to look behind.

"I'm 7B."

"I'm 8B."

It was two women with pitch-black armor inside, and the raindrops kept hitting their armor with a slight sound.

"Uh...... Hello ......."

Billy said with some embarrassment that the two men introduced themselves almost in no particular order, so he didn't tell who was who.

"Okay, 7B, 8B, I have a mission to call you out, you are now rushing to the location of the coordinates I passed to you, there is a train in that place, to protect the people on that train, your enemy is Ambrera's soldiers, remember not to show mercy."

"Yes!"

7B and 8B straightened their waists, slapped their left hands on their chests, then turned around and ran towards the coordinates given to them by 9S, the armor on their bodies did not affect the speed of the two of them in the slightest, and it only took a few seconds for 7B and 8B's figures to disappear into the darkness.

"Are they all right?"

Billy asked 9S with some concern, in addition to the armor on their bodies, the two young ladies only had two black knives on their waists, and Jiye didn't even give them a pistol?

"It's okay, this kind of battle is basically crushing for them, and there is no need to worry about their safety."

9S waved his left hand indifferently, if he fought with humans in this kind of rainy night, he could kill hundreds of soldiers without pressure just by relying on his reconnaissance-type android, not to mention the two combat types of 7B and 8B, and he was afraid that one person might be injured.

“…… Is it? That's right! You just said that Ambrera's soldiers were going to do something to a train?! Why? ”

Billy hadn't actually seen 9S's combat power, so he didn't say much, and then Billy remembered the order 9S had given to 7B and 8B, and asked in surprise.

"In order to extinguish the mouth...... When I arrived, I found that the train was about to enter the area, so I went to force the train to stop, but it was still a little late, and a group of T-infected giant leeches rushed out of the woods and pounced on the train. ”

"Then I used antitoxin to get rid of the leeches, but I completely destroyed the console in the driver's cab after I stopped the train, so the train is still parked in that place, and I originally wanted to wait until the mission was over before I went to take the passengers on the train."

"Then I just got the news that the Ambrera people found the train and found that the people on it were still alive, so they were going to send more soldiers over to kill those people."

“…… What is Antitoxin? ”

Billy frowned his brow in some distress, what 9S said was a bit informative, it took him more than ten seconds to digest the information, and continued to ask towards 9S.

"Antitoxin......"

9S pulled out a spiral test tube containing a green liquid from behind him.

"That's it, the thing we have researched that can destroy the T virus, it is transmitted by the wind, but it is also for this reason, although a bottle of antitoxin can destroy the T virus in the world, but it will take a few years, so our plan now is to directly attack Ambrera's laboratory that studies the T virus, so that all the T viruses can be destroyed more quickly."

"9S, I've finished dismantling, hurry up!"

After hearing A2's voice, 9S shrugged his shoulders and dropped the test tube on the ground, anyway, he walked towards A2 with his umbrella and 2B.

“……”

Billy looked silently at the shattered test tube on the ground, the green liquid in it quickly evaporated into the air, he walked over to the test tube and crouched down, sniffing near the test tube, but Billy didn't smell anything except the smell of rain.

'Let's hope what 9S says is true......

Billy stood up, his face solemn, and quickly followed the 9S and 2B in front of him.

"Just throw away the umbrella, I still have it anyway."

After walking into the tunnel, 9S casually threw the umbrella in his hand on the ground on the side, and his soaked boots stepped on the dry ground, making a "dada~" sound.

Billy also threw away the umbrella in his hand, and then grabbed the corner of the gray vest he was wearing with both hands, and took off the gray vest under the gaze of the three 9S people, revealing his sturdy upper body.

"Uh...... Can you not look at me like that? ”

There was a hint of embarrassment on Billy's face, he thought that after he took off his clothes, A2 and 2B would turn around, but they didn't expect the two of them to turn around at all, but stared at him silently...... It's embarrassing, hey!

"Hurry up, we're going to move on......"

9S pulled 2B and A2 around, they didn't have to dry their clothes like Billy, just ignore the discomfort caused by wet clothes.

“…… All right. ”

Half a minute later, Billy's voice came from behind him, and 9S turned around and saw that Billy was already dressed and walked over, and without saying anything, the four of them walked towards the depths of the tunnel together.

"What is that light?"

After a few minutes of walking in the tunnel, Billy and 9S reached the end of the railroad tracks, and then the tunnel was still unfinished, and through the light on the tunnel wall behind him, Billy could faintly see the piles of construction equipment and a faint light in front of them.

After the four of them walked over, Billy realized that the light was actually the light of a lamp, and below it was a rusty iron door.

"Squeak—"

9S walked over, grabbed the rusty doorknob of the iron door, and twisted it hard, pushing the iron door open.

"This is the sewer, 9S, are you sure you're going here?"

Billy frowned and asked 9S next to him.

"Well~ I don't care, and it's the fastest way to enter the cultivation center from here, so you don't have to worry too much."

This training center has been abandoned for ten years, and it was only recently reactivated by Marcus after his 'resurrection'. 9S didn't hesitate, propped his left hand on the ground, and jumped directly into the sewage below.

"Well, since you said so."

Billy watched 9S, 2B, and A2 all go down one by one, so he had to go down, but fortunately there was nothing disgusting in the sewage, and they didn't stay in it for long, and after following 9S and turning two corners, they came to the front of a ladder.

"This is it......"

9S went ashore, grabbed the iron crossbar of the ladder with both hands and climbed up, followed by Billy, after all, 2B was wearing a skirt, and it must be a man first at this time.

"Squeak-boom~"

9S pushed the iron plate above his head, and the iron plate that was pushed away fell to the side and smashed on the carpet.

“…… Is this the Ambrera Institute? ”

Billy climbed up as well, and found that they had actually come to the interior of a European-style building, and he looked around and saw that the furniture and wallpaper around him were in a dilapidated state, as if no one had lived in them for a long time.

But the lights on the walls tell Billy that the place is now inhabited......

"Attention, this is Dr. Marcus."

Just as Billy was looking around, an old voice suddenly rang out......
