Five Tiger Metalworking, formerly known as the ace group of Shudi, Chairman Li Changyu is the eldest son of the Li family in Shudi, it can be said that before the end of the world, the entire Shu land is a hall of the Li family. The Li family's industry, from scientific research, manufacturing, finance, real estate can be said to be fully rooted in Shudi, after the establishment of the Shu City Ring City, the Li family will shrink and concentrate all the industries, and the horizontal integration of various industries has accelerated the development of technology. The Five Tigers Metalworking is the representative of the Li family's military manufacturing industry in Shudi, and the famous T-9 land heavy armored combat vehicle of the Shuzhong Group Army is the masterpiece of the Five Tigers Metalworking. The T-9, known as the "big fuel consumer" and the "oil tiger", has three times the fuel consumption compared with the K-14 main battle tank produced by the Eastern Central Research Institute, so its endurance has been criticized. It is not used as regular equipment in the Eastern Country.

But the huge fuel consumption is exchanged for its furious power and combat output as strong as a walking land fortress. All the industrial design ideas in Shu are based on protection. As a result, the armor of the T-9 heavy tank can be called heavy. At its thickest, the armor is 1,700 mm thick, with blasting reactive armor, a bundle ceramic interlayer, and an inner layer of high-carbon honeycomb impact absorbing thermostats, plus external protective plates. Resistant to almost all types of armor-piercing, incendiary and anti-tank mines. Two pop-up 12.5 caliber rapid-fire machine guns with a rate of fire of up to 20,000 rounds per minute were buried under the armor plates of the combat vehicle. The source phased array radar can lock on anti-tank rockets and near-ground vehicles, and the roof is equipped with a multi-functional light rocket nest, which can launch ground-to-air, surface-to-ground and other light rockets. Directly under the face lamp in front of the explosion-type high-energy laser drilling rig, the composite steel plate within 1000 mm can be broken down in 2 seconds. Such a terrifying war machine, although the output is not much, but the Shudi Military Region still has a small number of its columns in the armored troops.

The core technology product of Wuhu Metalworking in the real sense is the J-15 exoskeleton mecha independently developed two years ago. Although there is flexibility in micro-manipulation, there is a defect that the volume cannot be reduced. The power mech's built-in twin-turbo micro-fuel engine is their main achievement. The hydraulic and pneumatic transmission of the twin-turbo engine produces a maximum of 350 hp of kinetic energy. It is equivalent to the power of a fuel vehicle. This allows a soldier wearing an exoskeleton to carry almost a ton of items without much effort.

However, a month ago, the final image of the two exoskeleton mechs that went out on a mission before they were dismantled by the horde of wild corpses made people shudder.

Among the mad corpses, a third type has appeared, which the lab calls the 'Mad Giant Corpse'. The more reactive exoskeleton armor has its more fragile joints, and it is torn apart by the berserk corpse in a single shot. In the past, exoskeleton armor was in an absolute advantage in the transport team, and wild corpses about the same size as humans, even if there were some special evolutionary types, they would not dodge and retreat. The offense is also mostly straight and jumping. So armor equipped with a chainsaw can be said to be a one-sided slaughter maniac. Although there will still be news of the destruction of the exoskeleton armor from time to time. But a one-sided fiasco like this one, which had no power to resist, made Five Tigers Metalworking step up the research and development of the second generation, that is, the X-20 single-soldier wearable mecha.

The armor in front of Ma Ji is the X-20. It was hoisted out of the storage room by the transmission. Ma Ji looked at the dark red armor in shock, and the words 'X-20, the first number' were sprayed on the left and right sides of his shoulders. Slightly taller than the 1.75-meter-tall Ma Ji, the head is integrated with a pitch-black glass cover, and the outer protective plate of the whole body is all stamped and formed by hot-melt alloy to present a streamlined structure.

Soon, two staff members checked and debugged and pulled out the hydraulic balance line behind the mecha. The mecha splits open, and the pitch-black honeycomb cushioning inside is understated and delicate. The external port on Ma Ji's body was quickly checked, and the staff motioned for Ma Ji to go up and mount it.

The entire chest of the armor bounced upwards to reveal the grooves of the humanoid shape in the mech, and Ma Ji reclined into it. I saw that the shoulders of the mecha were closed inward to clasp his shoulders, and after the positioning posture of the shoulders was corrected, the 48 probes on the inside of the mecha's back pierced into the exposed bionic spine structure like a carripede on Ma Ji's back. At this time, there was a whining bolt sound on both sides of his shoulders, followed by the closure of the breastplate, the closure of the leg armor, and the connection of all the joints buried in Ma Ji's body in the mecha was completed, the pitch-black mask fell and closed, and the waist bearing was locked. A horizontal band of light suddenly lit up on the pitch-black mecha mask, which was the part of the eye.

"The first machine is assembled and is being self-checked. After the self-test is completed, all functional parts are connected normally, and the power output is stable. An emotionless mechanical female voice rang out. This is a mech with built-in tactical assistance AI. Ma Ji began to feel a slight sensation of electricity coming from all over his body. At this time, Ma Ji, who was lying in the mecha, saw that the screen in front of him suddenly brightened and then spread, and then he felt that it was no longer a screen in front of him, but his own field of vision.

"Ma Ji, now that you've connected your mech, please start testing."

"If you can hear us, please raise your right hand."

Raise your right hand? How to lift?? Ma Ji was trying to move his right hand, and he suddenly developed his vision that his right hand really moved, but it was mecha.

"Very well, now please stand still."

Ma Ji tried to get up again as usual, and the mecha moved almost without a delay like an extension of his limbs. Ma Ji stood up, and suddenly felt as if he had become much taller, and his optic nerve was a little unbalanced, accompanied by the mecha shaking itself a few times, and suddenly sat down. Suddenly fell, making the mecha smash on the lifting platform and make a rumbling sound, everyone, including Ma Ji himself, was startled, and then Ma Ji found that he didn't feel it at all, and the built-in buffer layer buffered the shaking and vibration inside very smoothly. At this time, Ma Ji became bolder, he slowly supported himself with his hands, and gradually stood up. Although I feel that I have found a sense of balance, the surface of the mecha without a sense of touch is not the epidermis of a human after all. The sense of pressure, touch, and even distance needs to be cultivated over time. He raised his hands and put them in front of his eyes, Ma Ji could feel that as his fingers moved, he pulled the micro-force lever on the inner side of his fingers, and then the five fingers of the mecha also moved, Ma Ji held on to the escalator of the lifting platform, and finally stood up steadily.

"It's done!" The recorder and the project leader who recorded the whole process were full of excitement.

The three major technical difficulties of the X-20 mecha are miniature power, human bionic implantation, and synchronous human-machine language code translation technology. Got a perfect solution. Among them, nanotechnology, electromagnetic confinement reactors, and airborne tactical artificial intelligence are the products provided by the Central Research Institute, which has reduced the size of the mecha from the original giant height of nearly 4 meters to more than 2 meters, more comprehensive functions, flexible limb structure, electromagnetic confinement microreactor can be called epoch-making nanotechnology, the Central Council only shared the information document a few months ago. It was only recently that the finalization of electromagnetic fine-tuning in reactors came to an end. However, the disadvantage is that even if Wuhu Metalworking adds it to high-density and boron alloy as the shell interlayer, it still cannot completely isolate radioactivity. The human bionic technology perfectly solves the human-machine fit, and the on-board tactical artificial intelligence provides translation, which almost completely eliminates the delay in action. The high-pressure air-cooled reactor heat dissipation system can not only be used as a reactor to dissipate heat, but also turn it into a vector thrust to act on the auxiliary power of the mecha. At this point, the X-20 mecha can be regarded as an auxiliary power exoskeleton mecha in the true sense.

The adaptability of human beings can be said to be really amazing, five days later, the Five Tigers metalworking equipment test site, Ma Ji can already run to his heart's content, jump over obstacles, wade through waist-high deep water, and carry objects. There's even a building block session. He has basically adapted to the daily life of wearing a mecha, and can use the mecha to replace his limbs and do a lot of things.

The X-green light project has achieved initial success. The corners of the project leader of Wuhu Metalworking hooked up a smug smile. The matter of the mecha is solved, and the next thing is to formulate the training syllabus and produce the equipped weapons. For two months, he has been under tremendous pressure, and the top management of the iron ring even gave a death order, if after a month, there is no hope of the success of the project, he will wait for the roll to cover the cover and leave, and the incompetent person is suitable to roll to the outer ring to live.

As a high school dropout and a high school dropout, Mecha Dream is the coolest thing they see in movies that belongs to men, and Ma Ji never imagined that he would one day become a mecha master. Of course, he doesn't call a mechmaster yet. At most, it's called a mecha intern.

Because he seems to have found the feeling of the school again, no, ten times more stringent than the school. He can't take off his mecha, he has to wear it even to sleep, there are strict rules about what time to get up, what time to eat, and what time to go to bed every day, and there are only three theoretical courses for him: mecha functional structure, transport team tactics class, and weapon crash course. In such a closed environment, Ma Ji quickly absorbed the operation techniques of mechas, escort mission tactics and the operation and principles of various weapons. Then, in his increasingly heavy training, he needed to express the theories he had learned accurately. Ma Ji had never been so focused, and these days, apart from the occasional thought of his father, he had little time to think about his own problems. Life has been filled with all the training and courses.

At the same time, the assembly line of the Shudu Five Tigers Metalworking is running at full power, and the T-9 is being refitted. With the electromagnetic confinement reactor, in addition to the key power part, the T-9 was re-modified with a turbine conversion unit. It frees up the on-board power supply engine and provides auxiliary power by reverse transmission of power. The modification of the T-9 will completely get rid of the notoriety of "oil tiger" and become a real multi-functional infantry heavy weapon, and the endurance has been greatly improved.

With the assembly of the T-9, a chemical defense war group consisting of 100 people is being assembled. The Shudi Military Region also made major adjustments when the catastrophe occurred, downsizing the entire operational establishment and retiring a large number of grassroots officers and men ahead of schedule. They used the existing military fortifications and cooperated with Shudu to establish a huge military underground base in the southeast.

The development of cooperation is the result of the research of Shudu and Shudi Military Region on their own, and on the eve of the catastrophe, with the disappearance of Zhang Baizhang, commander of the Shudi Military Region. In addition to solving the problem of sharing and transmitting important technical data, basically the major cities in various places are in a state of autonomy, and in such a short period of time, the military districts of the whole country have only had time to make a full mobilization - all the unmanned aircraft flew into the sky and began to spread special lead clouds at an altitude of 20,000 meters. Priority is given to spreading to the periphery from the main densely populated areas.

Now there are several long cables over the Shu land, leading directly to the inside of the lead cloud, and there are several military giant fortress-type high-altitude bombing airships inside, which are constantly spreading black fog, slowly covering the stratosphere.

A few weeks later, on the road leading to Kangcheng in the northwestern suburbs of Shudi, the mechanical troops of the Shudu Chemical Defense War Group were slowly moving forward. Cannes is located in a remote area, but there is no excessive concentration of wild corpses along the way. Several war groups in front of them explored the way, and they had already swept away the scattered villages. However, the target area, the Cannes mine, is rich in ferromanganese and coal. This mineral is known as the blood of industry and is one of the most important strategic resources. Before the cataclysm, this place was once prosperous. These mineral resources have been developed and continuously carried out by large heavy carats to various places. Those mine owners sat on the ground to collect money, creating a large number of local tyrants. If there are many local tyrants, the money here will be easy to make. With the development of various service industries around this resource land. It is from this land that a million-level Cannes has developed. And now, here is a million-level frenzy of corpses.

Yang Chong was standing on the roof of the T-9, leaning against the armor plate of the launch nest, and was looking behind him with a telescope. Due to several defeats, the life of the anti-chemical warfare regiment was not easy, and each time they went on duty meant attrition. Especially in the last few times, the team escorting the resources has been wiped out. And they are like a relay race, the people in front are dead, and the people behind are pulling out to pick up the resources that the people in front of them send halfway. Such losses are undoubtedly enormous. Yang Chong believed that if they came here again, their anti-chemical warfare group would face a situation where no one was available.
