Fooling Tomoko into being a system

9s stood up from the pile of steel raptor corpses, "2b, the available parts have been collected!"

"Yeah!" 2b nodded slightly, "Let's go to the weapons merchant Aiko to buy upgrade materials and upgrade the night combat program to the night combat system!"

As for how to find Echo, I have to praise 9s. When selecting the weapons in Echo's suitcase, he successfully hacked a low-level magic weapon, turning it into a locator that only he could receive signals from.

This is why 2b and 9s can accurately find Aiko and buy parts and chips every time.

In order to prevent Aike from finding out that he is being followed, 9s will even wait in front of Aike with 2b.

After collecting all available parts of 2b and 9s, follow the source of the signal sent by the weapon to find Echo.

The two of them walked side by side on the ruined streets full of giant poisonous mushrooms, as if they had entered a fairy tale world.

9s glanced at 2b who was walking silently, "2b, don't you think a2's behavior is too strange?"

2b paused for a moment without stopping, "Find a2, you can ask her face to face! The most important thing now is to upgrade the night combat procedures."

[Record]2b is starting to become more and more standoffish, which is not a good situation.

9 seconds to write down a piece of data, and then close the record.

The two spent a whole day tracking Echo, and finally saw an abandoned road.

The two of them walked along the road. During this period, 9s kept looking for topics and tried to chat with 2b, but was interrupted by 2b.

"Look 2b!" 9s pointed to the remains of a small mechanical dinosaur on the side of the road.

The two summoned weapons behind their backs and were ready for battle!

"9s, you go check the body, I'm on alert!"

"Yes, 2b!"

Then 9s came to the wreckage and started inspecting it, while 2b started the night combat program and was ready to engage the enemy!

A small mechanical dinosaur, no more than half a meter tall. The entire iron skin has been corroded by rain, and a large area is yellowed and rusty. The iron teeth are intertwined in the huge head, with a short tail, thick legs, and small front claws.

It even looks a little cute, but with a slash to the lower left, it is cut in half, and the cut is smooth and flat...

9s: "2b, a2 killed it!"

2b: "Huh? a2?"

2b put away his weapon and approached 9s. He saw the flat and smooth sword wound of the small mechanical dinosaur. After comparing it in the data, he found that it was indeed a2's usual weapon.

A rare smile appeared on 2b's face, like ice and snow melting.

"It seems we have found A2, expand the search scope!"

随后2b和9s断断续续发现不少尸体，它们全被a2杀死，2b与9s两人一路沿着尸体追踪搜索了半天。

Although there are more and more corpses, a2 is still not found.

"2b, the location of these wrecks is strange! The path we traced along the wreckage was in a curved arc."

2b wondered: "What's the problem?"

"I mean, it doesn't look like the traces left by A2 being chased, but that A2 deliberately attracted all the nearby mechanical dinosaurs to this arc to kill them."

9s passed a map data to 2b. There were dense red dots on it. These red dots were exactly the locations of the wreckage collected and summarized by 9s. Countless red dots together outlined a red arc.

This red line gradually spreads backwards, and finally meets at the other end, forming a huge red circle.

"Based on the positions of these corpses, it can be deduced that there should be all mechanical dinosaur remains near this ring!" 9s made his own bold inference.

2b glanced at the huge red ring on the map, "Can all the mechanical dinosaurs here add up to form this ring?"

9s was stunned, "Let me calculate it!"

In the 9s, I started designing the data model and expanded the distance to the inner and outer sides of the ring by 100 meters. No, the number of killing density did not match!

200 meters, 400, 1000 meters...

9s: "2b, I used the distribution density of mechanical dinosaurs I met before as a reference model. Even if a2 kills all the mechanical dinosaurs within 1000 meters, the number of remains will not match the model calculation!"

2b: "Then redesign the model based on the number of wreckage!"

"No problem, 2b, this will take a while!"

2b stood between a large number of mechanical dinosaur remains, and also stood on the red ring, "9s, follow me, I have made some discoveries."

2b walked towards the ring and carefully observed the ground on the roadside.

"9s, there are a lot of messy paw prints of mechanical dinosaurs on the ground. It looks like they are chasing some prey!"

9s followed 2b while designing the model, "2b, you mean the mechanical dinosaur is chasing a2?"

"No, I mean a2 is drawing all the mechanical dinosaurs outward from the center of the ring and killing them all at an appropriate distance!"

"But why does a2 do this?"

2b did not answer 9s. If her judgment was not wrong, they would see a2 soon.

"9s, redesign the model to include all mechanical dinosaurs within the ring!"

Start building, calculating, and analyzing immediately in 9 seconds!

10 minutes later!

"2b, the model is established! How do you know?"

9s looked up at 2b with a surprised expression.

"Before we came to the ring, we occasionally encountered a few small mechanical dinosaurs. As we got closer to the ring, there were fewer mechanical dinosaurs. Especially now, we have been inside the ring for 10 minutes. Have you seen one alive? Want a mechanical dinosaur?”

9s thought for a while, "In the 10 minutes since I entered the ring, I have indeed not seen a single living mechanical dinosaur. Even the wreckage has only seen one or two, and they are all small mechanical dinosaurs, and there is not a single large mechanical dinosaur." Discover!"

9s suddenly thought of something!

"2b, what you mean is that a2 will lead all the mechanical dinosaurs in the ring to the edge and kill them. This is too time-consuming. A2 does not have the help of the auxiliary machine! Even with the help of the auxiliary machine, it will not be able to connect to the bunker server. Under such circumstances, how she found all the mechanical dinosaurs in the ring probably surprised me more than her killing all the mechanical dinosaurs."

"I don't know. When we find a2, you can ask her yourself!"

9s suddenly lowered his head and asked him to ask a2 personally...

2b: "9s, do you remember what Aike said?"

9s: “What words?”

"We are the only artificial people in the Kingdom of Darkness who bought night vision chips from her, and she thought we were the only customers."

9s: “Is there anything special about this?”

"A2 and I are both E-types, so the difference in combat effectiveness between the two should not be big. Plus, A2 never repairs his body, so my combat effectiveness may be stronger!"

2b saw a 5-meter-tall giant mechanical dinosaur in the distance, and immediately quickened his pace, "Without the night combat program modified by 9s, even I would have struggled to face a group of mechanical raptors!"

"How did A2 kill so many mechanical dinosaurs without purchasing a night vision chip!"
