Liu Xin relied on the map and qi sensing technique, and successfully left the range of the magic capital with the mine that day, and came to a forest.

"Landmines, let's wait here, I'll help you get the mechanical arm and equipment first, you help me look around, what functions do you want to order, I'll see if I can make it."

"Can you still choose a function? You see, it's better to have something that can be defended. "Landmines don't matter, and now I haven't found out what specific functions are needed, so I can only ask for a defensive one first, after all, the mine's own defense capability is somewhat weak.

"Defense? I'll think about it first, let's take a break and give me some time to think. Liu Xin doesn't have any good ideas for the time being, this robotic arm needs to see what type of store sells first.

"Rhapsody, make a list of redemptions for defensive mechanical arms."

"Defensive mechanical arms need to be exchanged for mechanical arms first, and then defensive weapons such as laser masks can be added to them." Liu Xin found out for the first time that the system would be like this, usually he said the exchange option by himself, and the system helped him list a series of things, and then selected it himself, probably because this exchange was divided into two parts.

"Okay, then list the exchange for the mechanical arm."

"A total of 16.47W species were searched, including human arms, animal arms, fish arms, screening human arms, a total of 1.7W species were searched, all human mechanical arms are the same shape, but the materials used are different, which makes the strength different, resulting in a variety of classifications."

"Okay, just make a list of the first one."

"Mechanical Arm (Initial): An arm made of steel, strength level F-, 5 weapons can be added to it, basic mechanical engineering knowledge is required to install, and 100 points of first-level energy are required to exchange."

"Yes, you have to learn the installation knowledge first, hey, it's troublesome, I want to exchange the blueprints of a robotic arm first, as well as the design drawings of the simplest several robotic arm weapons, and then open the learning space, learn the production of the robotic arm, installation, maintenance, and a series of other just."

"Ding, exchange the design drawings of the first generation of mechanical arms, 37 designs of portable weapons, a total of 750 points of secondary energy, the production, installation and maintenance of mechanical arms only belong to exoskeleton technology, and learning exoskeleton technology requires 7 points of tertiary energy, do you want to learn?"

"It's so expensive, I hope I can really get what I pay for, I have to make the best mechanical arm for the mine, and the mine is not there now, let's learn."

The familiar feeling of weightlessness struck again, Liu Xin had already entered the study space, and the next thing was the busy study time. Liu Xin has been studying in the learning space for three years, and at first he thought that it was not a difficult technique, relying on his strong attributes, it could definitely be completed simply, but when he began to learn Liu Xin, he knew how difficult it was, and the entire exoskeleton technology was learned from scratch. From the simplest metal support skeleton, to the later individual combat armor, and then to the production of individual driving robots, and finally to the production of Gundam, if it were not for the powerful attributes, these knowledge alone could make Liu Xin unable to learn for a lifetime.

Liu Xin, who came out, only felt that he was about to go crazy, and now Liu Xin wanted to vomit when he saw tools such as wrenches. However, in order to let the mine have a strong mechanical arm, Liu Xin endured it, and now Liu Xin can live very well with his powerful exoskeleton technology even if he loses the strength of his whole body.

"I'm finally done, and it's really not something that anyone can learn about this knowledge, and I'm about to collapse. After suffering so many sins, you must help the mine make a powerful mechanical arm, or you will be sorry for suffering so much. Liu Xin casually found a piece of paper and began to design a mechanical arm for the mine.

Liu Xin prepares all the materials to make by himself, after all, he has forging in hand, and he can make precision parts even if he doesn't need tools. At this time, the mine came back, and he didn't bother Liu Xin when he saw Liu Xin burying his head in drawings, and you can guess that Liu Xin is designing a mechanical arm for himself.

Liu Xin was busy for two days and three nights before he helped the mine design the mechanical arm, and the drawings alone drew a tall stack. The design was ready to be made, and the iron ingots and furnaces that had not been used for a long time were removed, and a lot of materials were taken out, and even the corpse of the Tyrannosaurus was removed.

Liu Xin first took off one of the thighs of the Tyrannosaurus, which was prepared to be used as a living material, after all, the best material in the body was the corpse of the Tyrannosaurus. Or is it because Liu Xin's attributes have been greatly improved, otherwise he would not be able to deal with the corpse of the tyrannosaurus at all.

Liu Xin began to smelt the thighs of the Tyrannosaurus, but the problem of attributes made the smelting particularly slow, until three days later, only half of the corpses were smelted, and Liu Xin at this time could no longer bear the consumption of gas, so he had to stop and rest.

When I turned my head and looked around, I saw that it was night, and the sky was full of twinkling stars, and there was a moon that was really full.

The moment he saw the moon, Liu Xin's consciousness began to blur, and then he lost any consciousness. The mine has been resting beside it, and Doomsday has made the mine not sleep too deeply at all, and will immediately get up and be alert as soon as there is movement.

"Boom" A strong tremor directly woke up the mine, and the mine woke up and was directly frightened, and a huge brown ape appeared next to him, at least more than 10 meters high, and his whole eyeball was red, which made people shudder. The moment he saw the ape, the mine felt a strong threat, and he couldn't raise the consciousness of resistance at all, and was directly frightened in place.

The big ape also found the mine, and directly raised his foot and stepped on the mine, at this time the mine was already frightened, and he didn't know how to dodge, even if he wasn't stunned, he couldn't avoid the speed of the big foot.

The ape's big foot continued to step towards the mine, and at this time, the mine was finally awakened by the strong wind pressure, but found that the big foot was already in front of his eyes, and he couldn't dodge it at all. The mines were also abandoned, ready to wait in place to die.

At this time, a bright red phantom slashed through it, and directly knocked the mine to the side, avoiding the trampling of the ape. The mine that flew out noticed the red phantom, which was the little tiger that had been in Liu Xin's arms before, and it was the little tiger who saved the mine's life at the critical moment.

The mine that woke up didn't care so much, so he got up and ran away, and the little tiger also ran away with the mine. When the mine ran out of the woods, it was found that the ape had no consciousness to think at all, and was completely unconsciously destroying its surroundings. The whole forest was turned over by the great apes, and there were potholes all around the apes.

The mines outside the woods watched the ape rage like this, and the ape opened its mouth wide at this time. A shining spot of light appeared in the ape's mouth, and it continued to grow.

"Bump!" The point of light in the ape's mouth erupted into the distance as it covered the entire mouth, forming a huge column of energy.

"Boom !!" After the energy pillar fell to the ground, a large explosion was formed, and a huge mushroom cloud was directly raised, and the shock wave formed by the explosion blew the mine far away, and it was still spreading into the distance.

"Roar, Roar, Roar, !!Roar, Roar, Roar, Roar, T The ape also stood upright when the energy pillar exploded, constantly beating its chest and letting out a loud roar.

An eggshell-like light shield appeared on the little tiger's body, blocking the impact of the shock wave, and the mines could feel the pressure emitted by the little tiger.

The roar of the "roar" ape stopped, and he turned his head directly in the direction of the mine and the little tiger, and took a direct step towards the mine and the little tiger.

"Oh no, flash flash, the big monkey is coming." The mine also ignored the aftershocks of the shock wave, and beckoned the little tiger to continue running, while the great ape, like a hungry person who saw food, stared at the mine and the little tiger, and kept chasing after it.

"By the way, what about Liu Xin? Where did he go? In the process of running, the mine finally remembered that he hadn't seen Liu Xin, and began to ask the little tiger next to him.

The little tiger was also very cooperative, pointing at the big ape behind him with his paws, and making a characteristic sound.

"What? That monkey is Liu Xin? How is it possible, don't be kidding, let's run first, let's go back in a circle to find Liu Xin. "The mine didn't believe in the little tiger at all, and was going to go back in circles to find Liu Xin.

"Roar!! The peculiar roar of the ape came from behind, and the mine turned his head to take a look, and found that the distance between the ape and himself had been shortened by more than half, and he was about to catch up with him, and the mine could only turn around and throw two fireballs at the ape, trying to stop the ape's speed.

The two fireballs did not cause damage to the ape at all, and were directly smashed into pieces by the ape's huge body, and the mine could only helplessly speed up and continue to run.

The distance between the ape and the mine was shrinking, and when it was about to catch up with the mine, the little tiger was powerful again, and directly burst out with a light shroud enveloping the mine. The light mask continued to rise with the mine, and slowly floated into the air, and the ape also reached the bottom of the mine and the tiger cub at this time.

Because they can't reach the tigers and mines in the sky, the apes can only wander around the ground and constantly wreak havoc around them. The ape vented for a while, slowly opening its mouth to the sky, and the familiar point of light reappeared.

"Rub, let's do this trick again, let's flash quickly, don't be hit head-on." Before the mine's words fell, he felt the light shield move to the side.

"Pop" the energy pillar grazed the light shield of the protective mine and shot into the sky, and the mines in the light mask could feel the high temperature in it, even if it was a fire type ability, he couldn't bear it.

After the ape sent out the energy column, it also rested in place with some gasp, and the little tiger also took advantage of this time to stop the movement of the light mask. The two sides were in a stalemate, the little tiger rested when the ape rested, and the little tiger moved quickly when the ape used the energy pillar. The two sides continued to stalemate until the sun was about to appear, when the ape finally stopped, looked up and stared at the little tiger in the sky.

The mine thought that the ape had some trick again, and he also stared at the ape, and the next thing almost scared the mine away. The ape slowly floated up in the mine's sight, and its feet began to leave the ground.

"What? This monkey can actually fly?! Can you still have fun? "The mine is also a little discouraged, after moving all night, the little tiger is also fast and can't, and then the movement speed has been significantly slower, and now the ape can actually fly, which is completely bullying.

The ape slowly ascended with the sunlight until it was parallel to the tiger cubs, and the ape finally stopped, ready to fly towards them. The ape had just flown forward for a few meters, when it suddenly stopped, and continued to shrink until it became the size of a normal human before it began to fall downward.

"I'll go, it's really Liu Xin, how could he become a big monkey? It's magical. Seeing the process of the ape becoming a human, the mine finally believed that the big ape was Liu Xin's change, and at this time, Liu Xin's clothes were torn all over his body and began to fall quickly towards the ground.

The little tiger also covered his eyes with his paws humanly at this time, but he was still secretly looking at Liu Xin.

"Yo, are you still shy? Let's go down and see what happened to Liu Xin. At the suggestion of the mine, the little tiger slowly fell towards the ground.
