Cortana is an artificial intelligence for scientific research, and due to the limitations of the basic code, Cortana cannot use weapons to attack intelligent creatures, nor can she enter, store, or output weapon drawings, nor can she produce weapons independently. So Cortana didn't bring any powerful weapons to get Gou Cao out of trouble.

However, among the communication signals hijacked by Cortana, there are two drawings that can change the current embarrassing situation, one is the robot mouse for exploration, which can be operated remotely, and has a certain ability to dig into the ground and carry items. The second is the field medical cabin, which can use 3D printing technology to repair the damaged parts of the organism.

Gou Cao thought that he was going to be Yang for the rest of his life, but after hearing about this thing, his mood instantly improved. The blueprints of the neural communication device were brought with Cortana when she escaped.

After escaping to the rover, Cortana used 3D printing more than a dozen mechanical mice in order to get in touch with Gou Cao, and before implanting a subspace storage device and a neural communication device into the back of Gou Cao's head, she roughly figured out the current situation in the auto repair shop.

After the garage was overrun by the corpse chasers, it was turned into an outpost. The original basement has been overhauled, with the exception of the power supply room and the storage and refrigeration rooms. To the east is the Corpse Eater's Quarters, which resemble a group dormitory, with each person having a bed and an iron box for personal belongings.

To the west of the underground is the dungeon and the zombie captive area, and the sound of tearing flesh and chewing bones that Gou Ke heard that day came from the zombie captive area next door.

In order to appease the zombies, the entire outpost is not allowed to make too much noise, which is why Gou Cao's mouth is taped to prevent him from screaming.

The above-ground part of the garage has not been significantly altered. The original garage is still a place where various vehicles were transformed. The original living room of Gou Cao is now the residence of the priest, and the first floor of the warehouse is divided into several small rooms for a few small cadres to live in, and the second floor is used to store munitions.

The open space to the north is home to four or two infantry chariots, a personnel carrier and the Grim Rover, a section of the surrounding wall that has been gated into iron for chariots to enter, and a flat open space outside the fence for dozens of motorcycles and other oddly shaped modified vehicles. The watchtower has been reinforced with a 25mm cannon and night-vision cameras, and there are corpse chasers guarding it at all times.

Based on the above, the advantages that Gou Cao can now take advantage of are subspace storage devices, robot mice, and Cortana.

There are also two steel crossbows and more than 200 crossbow arrows in the subspace storage device, and at the same time, they are invincible in digging the ground; The stealth of the robot rat can help Gou Cao to detect the corpse chasers in the outpost at any time, and Cortana, who can act independently, can be a great help when she establishes contact through a neural communication device.

The above premise is to confirm that this Cortana is credible now, but in the current situation, there is no other way out except to trust Cortana, so it is better to fight.

The things that need to be considered for Gou Cao's escape are also obvious, first of all, during the period of escaping from the dungeon and sitting on the rover, a large number of corpses and zombies will become an obstacle. Then, when escaping in the Rover, it is also a problem to escape from the pursuit of the corpse chasers with a large number of vehicles, and the fire from the 25mm cannon can also pose a considerable threat to the Rover.

Now I have the tools and Cortana's help, and I know the corpse chaser. Then it is not impossible for Gou Cao to escape from here.

Cortana can't collect weapon blueprints, but she can; Cortana can't attack humans, but she can; Gou Cao can't move, but Cortana's robot mouse can. In the case of complementary advantages, it is not impossible for the corpse chaser outpost to make trouble.

Cut off the conversation with Cortana, the time was still in the middle of the night, Gou Cao was not excited and couldn't sleep, whether there was a way out is one thing, but it is also important to save the physical strength that can let him go out. Knowing this, Gou Cao, who was already quite calm, fell asleep peacefully.

Soon it was dawn, and after eating a painty breakfast, Gou Ke controlled the robot mouse to start the first step of the plan.

In order to prevent the robot rat from being discovered, the only way to do it is to use the digging function of the robot rat to burrow underground when moving between the various areas of the skirmish. Cortana naturally knows this. However, because it is necessary to avoid being noticed, a large number of clods of soil cannot be discarded, and there is no place to go behind if the soil dug in front is not filled, and the rat holes that Cortana digs are all disposable. So when it came to Gou Cao's side, he could only dig a hole again, and he couldn't be lazy.

Robot rats burrow faster than regular mice, but not much faster. After two hours, Gou Cao finally controlled the robot rat to dig through the rat hole that had entered the arsenal, and the excavated mound of dirt was blamed and stored in the subspace storage device.

The arsenal sounds remarkable, but most of them are grandfather weapons that have been retired before the end of the world. Almost all of them are light firearms with a caliber of no more than 7.62 mm, and the only explosives are grenades and grenades, and they are scarce. Overall, it's relatively shabby, but given the country's policy of banning guns before the end of the world, it's quite rare for non-military organizations to have these weapons.

The main business of robot rats is to explore narrow and dangerous places when conducting scientific expeditions. Affected by its size, its carrying capacity is quite limited, and there are not many things in the arsenal that can be carried away with robot mice, only various types of bullets. Grenades and grenades were too large to move. But that's enough.

The first was for the robot rat to smuggle one of the 5.8mm rifle rounds to the rover print room for scanning. Obtained bullet blueprints.

If there are multiple structures in an item, then scanning the item will not only give you a drawing of the item as a whole, but also a drawing of its individual components that can be separated from the general drawing. The 5.8mm bullet was obtained in order to obtain the primer and propellant blueprints in it.

The main component of the bullet primer is mine mercury, which is extremely explosive, and Gou Ke only produced some in small quantities by remote control printers. The propellant is nitrocellulose, a white cotton wool-like explosive, which is equally dangerous and is mass-produced.

While the printer was producing at full power, Gou Cao commanded more than a dozen robot rats to dig a pit under the floor of the underground residential area, moved all the bullets in the arsenal to bury them under the pit, sprinkled mercury with mine mercury in the middle and connected to the remote control electrode. In order to avoid detection, another batch of empty shell bullets was produced and placed in the arsenal.

Soon, a lot of nitrocellulose was also produced, and Gou Cao used these nitrocellulose to transform the arrows fired by the crossbow arrows fired from the big crossbow on the roof of the car, so that the crossbow arrows fired could maintain high penetration while increasing the explosive effect.

Everything was ready, and Gou's mood was much lighter, so that when he was hit with an axe in the evening and was "hemostatic and disinfected", he was not so painful.
