Compared with the southeastern base camp that has achieved extreme defense under the conditions of existing resources, the defense of the North City Security Zone is very fragile.

The outer defensive walls of the northern city are all made of concrete, steel and other commonly used building materials before the catastrophe.

Aside from the fact that the interior is mixed with a lot of scrap metal and vehicles to strengthen the defenses, there is no sign of extraordinary reinforcement.

Under the volley of the Death Archer formation, Qi Rin was confident that he would evaporate their seemingly tall and sturdy defense layer in an instant.

Even the foundations are not reinforced without any extraordinary reinforcement.

"Aren't they afraid that there will be ground-burrowing demon species attacking directly from the ground?"

"It's not that I don't have the ability, and I won't think of it."

"But this defense"

Qi Rin was a little confused, not understanding why the defense of the northern city was so undefended.

Compared with the southeast, the north city can be called tofu dregs.

Qi Rin felt that with the defense of the northern city, even if he included all the undead in the space of the dead, he would go in directly and blossom inside.

On the contrary, the southeast side is too regular, and if you attack, you can only grind slowly from the outside and blossom from the inside?

Qi Rin said that he wouldn't go over there.

While thinking, a ghost's report came from within the soul link: "Master, that shadow has gone and returned, judging from the trajectory of its movements, the shadow has been avoiding our anti-hidden props, and it seems that it doesn't want to have any conflict with us." ”

At this stage, the anti-hidden props can be seen by both the enemy and us.

This common anti-stealth prop is equivalent to a flickering alarm.

If the stealth unit has to force its range after seeing the alarm, then the anti-stealth item will warn, explode, counterattack, mark, remove and so on, depending on the quality of the anti-stealth item.

In the past two months, Qi Rin has also obtained a lot of anti-concealment props, but most of them are placed near the main body.

He's not arrogant enough to fill the city with props.

Previously, the shadows seemed to have the idea of scouting and surrounding the Beicheng mixed group, but they were all persuaded to retreat by the anti-hidden props.

Then he ran back to the southeast, and then turned back not long ago.

Now it's back to the southeast.

"Yo, there are really surprises, but it's a pity that the quality of the anti-hidden props is too low, and I can only persuade them to retreat for the time being, but I can't stop them."

Qi Rin thought so, but he didn't have the slightest regret.

At least, he knew that the military had a stealth unit.

And this unit, at most, is an errand and messenger.

After the letter was delivered, Qi Rin was very much looking forward to more surprises.

"It's a pity, why don't you come to me."

There are several high-quality anti-stealth props near Qi Rin's main body, and once that shadow comes to investigate, it will be dispelled as soon as possible, and then captured by the nearby undead.

Qi Rin shook his head and stopped thinking about this shadow matter, and instead thought about the silver-rank skeleton mage skill.

Recovery.

In Qi Rin's opinion, it is a good skill that can recall the undead who have lost their soul fire.

The strength of the resurrected undead after resurrection, depending on the time when the soul fire was lost, has no branding.

But even so, in Qi Rin's opinion, this skill is still very good.

Just imagine, after absorbing all the artillery fire of the other party, the sea of the undead will be resurrected with a wave of his hand

"Well, Xiao Di's miniature mecha can actually be developed."

Qi Rin was thinking about his own affairs, when suddenly his mind turned to the mechanic.

Doing push-ups, he got up from the ground, took out his little notebook and wrote on it:

Let's go back and talk to Xiaodi, the development idea of micro UAV armor does not have to be confined to refinement.

Turning into an assembly line, shoddy manufacturing is not indispensable.

With black hole fireworks, it can be used as a one-time explosive class.

There are even many ideas that can be developed after the activation of the enemy such as suicidal charge of air propulsion and underground standby ambush

Dots of starlight shine through the top of the bare field and sprinkled over the mountain of corpses.

The cold wind wrapped the corpse and stenched against the hem of Qi Rin's cloak.

The pen in his hand continued to record the planning ideas to be considered in the black notebook.

Whenever there was information about a ghost coming from within the soul link, he would quickly record it in the book and think about it carefully.

At this time, the ghost boss next to him will accurately calculate the time according to Qi Rin's instructions, and whenever the undead cooldown time is over, the boss will remind Qi Rin as soon as possible.

In addition, many copper bones carrying corpses are constantly brought here, and the corpses are thrown on the corpse mountain to replenish new materials for the master.

Qi Rin would also do push-ups quickly in his spare time when he didn't need to record for the time being, while his mind replied to the questions of the ghosts scattered in all directions.

This kind of work process, Qi Rin estimated that it would not end until dawn.

After dawn, he was scheduled to sleep for four hours, during which time the commanders of the undead would rationalize the distribution of the newly replenished men and prepare for the upcoming battle.

At the same time, these four hours are also the arrival time for Qi Rin's surprise.

Qi Rin got up from the ground panting, took out the protein powder brewed in advance and took a sip.

Vanilla-flavored protein powder, Qi Rin couldn't taste anything at this time.

I don't know if it's mental exhaustion, or if the sense of taste is gradually disappearing as the body becomes lower.

Qi Rin could only smell the stench of corpses now.

When the sky is about to break.

A residential house near Qi Rin's location is brightly lit.

In the corner of the living room, the child is lying under Xiao Di No. 1 and doing modifications.

At this moment, Xiao Di No. 1 has completely changed its appearance.

From the original upright walking robot, it has become a four-legged robot today.

The child held the Void Alloy given to him by Qi Rin and aimed it at the robot's chest and abdomen, where there was a strange hollow ring with seventeen extremely thin metal hands on the inside of the ring.

After a long time, when the child's eyelids trembled and cold sweat flowed, the purple quality alloy finally turned into a pile of liquid, which was slowly separated from the main body to the ring, and then slowly fixed under the interference of mechanical power, becoming the eighteenth pointer.

"Whew, yes, there's still one thing left to succeed!"

The child's legs were strained, and his body slashed out of the robot's lower body, and his face was full of joy.

The use of mechanical power not only requires mental values, but also requires concentration on shaping, molecular changes, etc., a careless, may be the end of material destruction and waste of mechanical power.

If it is an ordinary material, the child will definitely choose to continue the operation.

But this purple quality material is too precious.

When he asked Qi Rin for materials, the child also had the courage to ask for them for a long time, and at that time, the child didn't know that the materials he wanted were purple quality, and only thought that they were ordinary.

Qi Rin, as the party concerned, was also very puzzled and didn't understand what the child wanted the materials for.

And when you open your mouth, you want purple quality materials!

With this kind of quality material, Qi Rin has summed up a lesson for more than two months: the chance of getting it is only on the same type of demon seed that he kills for the first time, and the chance of getting it is only on the high-level demon seed.

And what's interesting is that even high-level demon seeds, if it's not the first kill, the quality of the things obtained is very average.

So far, Qi Rin has obtained very little purple material.

Although he won't need these things for the time being, after finding the enchanter in the future, it will be necessary to build equipment for the high-ranking undead.

However, thinking of the child's conscientious and meticulous work during this time, Qi Rin, who has always been diligent and thrifty, didn't think much about it, and met the first request made to him by the child at that time, and gave the child enough materials with a wave of his hand, and even gave more, when the child was excited and about to jump onto the roof.

When the child was modifying the outer body around the four-legged Xiao Di No. 1, Xiao Di's eyes flashed green, and a mechanical voice sounded: "Xiao Di, didn't Uncle say to let you sleep, why don't you sleep." ”

The child wiped the beads of sweat from his forehead, and while continuing to inspect the strange body of the modified Xiao Di No. 1, he bared his teeth and smirked: "I'm afraid of the dark!" I can't sleep. ”

"Moreover, grandma is not in good health, sometimes, when she goes to hang a drip, she will put me in the teacher's house, the teacher is a good person, and he takes care of my food at noon, at that time grandma often said, when I am in someone else's house, I must be diligent, so that others will not hate me."

Xiao Di No. 1's LED eyes flickered, and he asked again: "Then why, don't you tell your uncle, you are doing this for your uncle, is it because you want to surprise him?" ”

The child was stunned for a moment, and then said happily: "Ah! You're thinking about it! It seems that the new updated smart machine protocol for you has worked! ”

"Yes, I'm collecting data on human behavior, etc., maybe I can evolve in the future." The mechanical voice replied honestly.

"Yes, I'm going to surprise my uncle twice," the child paused, holding his forehead and shaking it vigorously a few times.

He felt a little dizzy, and his heartbeat was pounding.

"It's strange, the spirit is still a little bit at the bottom, how can you be dizzy."

"Huh? How did your physique decline? Hmm, I guess I stayed up late, and one more pointer is done, Xiaodi! Little Di! Keep it up! ”

The child thought it was caused by overuse of machinery and staying up late, but he didn't think much about it.

He clenched his fist in one hand and held it in front of him to cheer himself up.

After a while, feeling that the state was almost restored, the child replenished the last metal needle for Xiao Di No. 1.

"Xiao Di No. 1, we're ready to make it!"

"The order has been received, please replenish energy."

The child carefully took out a translucent blue card transformed from a high-grade purple quality material [Concentrated Energy Crystal] from his pocket, and gently inserted the card into the card slot that popped out of Xiao Di's forehead.

Xiao Di's eyes flickered, and the mechanical prompt sounded: "Energy is sufficient, waiting to put in the materials." ”

At the same time as the mechanical sound sounded, in the chest and abdomen of the machine, nineteen metal needles actually flashed blue electric light!

It's mechanical power!

That's mechanical power!

At this moment, the child didn't understand what the gadget he had inadvertently concocted in the process of preparing Qi Rin's surprise meant to the world!

At this moment, the child just stared at it vigorously, and took out a [Nebula Stone] and a [Space Scale Crystal] with great care, and slowly placed them on the flickering mechanical power in the robot's chest and abdomen.

When the two crystals were suspended in the center of the guide, a large amount of artificial mechanical power was instantly wrapped around it, and then, like dense ants, those mechanical forces began to peel off the material on the surface of the crystals, and then slowly fused them into the shape of buttons!

"It must be successful!"

The child stared intently at the buttons that were about to form, and kept praying in his heart not to fail.

Although Qi Rin was very generous when he gave the materials, he didn't even hesitate and gave more.

But the moment the material is obtained, when the child sees the annotations about the material popping up on the panel.

Only then did I understand how precious these materials that Xiao Di No. 1 had been looking for but had never found.

Purple quality, all these materials are purple quality!

This is too precious for children who have never even seen white qualities.

Because of this, the child is even more like sitting on pins and needles, for fear of damaging these materials.

The buttons quickly took shape, and when the purple buttons with residual warmth fell on the child's little hand, which had been sticking out of his eyes.

The relevant information pops up on the panel.

[Item]: Dimensional Anchor Button (Special Edition)

[Quality]: Purple.

Note: The internal space is 10X10 cubic meters, which can be bound to mount weapons, and can be bound to various props and equipment.

Note: When the wearer enters the dimensional space, the bound item will be automatically contained in the dimensional anchor button, and when leaving the dimensional space, the bound item will automatically appear in the anchor position before containment.

The original usage of the dimensional anchor button was that it could be used to float some large support machinery, and then position it to fight in a high-altitude crash style.

In addition, when large machines are stored in items such as space rings, or when entering dimensional space, the attached armor attached to the containment is used to prevent loss.

But now, this thing has been transformed by the child into a must-have for Qi Rin's undead.

After reading the annotations, the child thought carefully that it should be no problem, but the specific results will have to wait for the uncle to come back and let the uncle test it himself.

He carefully placed the button in his pocket and prepared to test the second form of Xiao Di One.

Vehicles!

The child found that every time he and his uncle moved, it was either jogging or Uncle Sunglasses running around with them.

Especially when it rained tonight, they were walking slowly, and suddenly my uncle didn't know why, so he asked Uncle Sunglasses to run here with them.

The child always felt that Qi Rin should need a vehicle.

In order to make Qi Rin happy, he added the second transformation form of Xiaodi No. 1 on the basis of being able to independently create space buttons.

"Little Di No. 1!"

The child crossed his waist with one hand and pointed at the four-legged robot with the other: "Deformation!" ”

With a click, it sounded.

The original appearance is a hollow ring with four legs and a chest and abdomen, and the ring is surrounded by metal needles, and the grotesque robot instantly retracts its four legs, then arches its waist and bends forward, while turning its elbows and knees, making its body gradually narrower and flattened.

At the same time, the head and tail protrude from the sides of the body, forming a scooter without wheels.

The exterior retains some robotic elements, with the original four mechanical legs at the rear and a light source similar to a headlight at the front, as well as a dashboard and console that the driver can easily control.

The whole design of the deformation is focused on maintaining the harmony and fluidity between the robot and the scooter form, so that it can both function as a button maker and be a practical means of transportation.

When the child came to the front of the car, his little hand reached out to the blue translucent card that popped up on the front of the car, and after a light touch, the mechanical sound sounded.

"Drop, identity confirmed, confirmed, Xiaodi."

As soon as the mechanical sound ended, the scooter hummed and instantly levitated from the ground!

Even the tail ends of the original four mechanical legs in the tail quickly began to transform into four thrusters emitting blue light, and the blue light flashed and flashed, ready to output at any time.

"The start is complete, I wish you a safe journey!"

The child lay on the ground and observed the base of the hovering pedal, where a thruster-like thing was running in blue light.

After the child got up, he took out the small computer he carried close to him, and quickly connected the front slot to the car head through the data cable for body data status detection.

"The installation of the bottom suspension crystal is a little off, and it will be changed later."

"According to the propeller efficiency estimate, a speed of 300 kilometers per hour is not a problem, and the energy supply of a concentrating spar can reach about 28 hours, and if a better energy source can be found to replace it in the future, it will be more durable."

"The reserve energy can be hot-swapped and replaced, so long working hours are not a problem."

"Hmm, the purple material given by my uncle is good, and the stability and energy output are good."

"The self-charging built by Nebula Stone is also very good, and it can be fully charged with a backup energy source in two nights."

"Autonomous driving."

The child held the computer and carefully checked the data.

With the help of the smart machine protocol, even if there is no actual running test, the information of the actual vehicle condition can be quickly compared under the comparison of big data.

The vehicle was activated and the child originally wanted to be recognized by his face.

But since Qi Rin and Hei Feng were both wearing masks, and Hei Feng was also wearing sunglasses, he took his fingerprints.

In the collection of fingerprints, the child only collected Qi Rin's, and Hei Feng's was very strange.

So the child set the start key to his and Qi Rin's fingerprints.

Originally, the vehicle form had wheels, but the child found that Qi Rin had recently looked at the world map and drew a lot of lines to the south and north.

Qi Rin told him that when the fog cleared, he would go to Jinling, so he planned first.

Because of this, the car was changed by the child to the current suspension.

Considering that my uncle said that the world will expand a lot in the future, and the terrain will also have new changes, it is complicated.

The child wants to configure several hovering robots to be used as lighting for night rushing, as well as to detect road conditions in advance for live return assistance.

However, the problem of independent energy cannot be solved for the time being, and it can only be retrofitted in the future.

After some fiddling, the child put away the small computer satisfied.

The small hovering pedal in front of him has all the same data as his carefully designed sketches.

With only a few minor changes left, this surprise for my uncle is complete.

The child looked at the hovering scooter carefully, and the outer body of the car was still the original color.

"What's the best way to paint it?"

The child scratched his head and thought about the design of the exterior paint.

Suddenly, he thought of his favorite, the feeling of hiding in his mother's poncho when it rained as a child.

At that time, he would guess where the car had turned and stopped, and then quietly open a corner to see if he guessed correctly.

If you guess correctly, you'll be super happy.

However, if it is too windy, the two sides of the poncho will blow into waves and shake them off, and you will be responsible for holding both sides while sitting in the back

"I like to hide in a raincoat and blindly guess where it is."

"Hey, hey, hey"

The child giggled and thought of the color of his mother's car, pink.

"Good! Just the color of Mommy's car! ”

The children have already prepared various colors of oil paint, but they have not yet chosen what color to use.

At this moment, the child is holding the pink oil paint and starting to spray it according to the appearance of the mother's little scooter in his memory.

Time passed, and soon the sky was completely clear.

The child, who had been busy all night, was seriously spraying pink paint, and at this moment he had no idea of the various uses of high-grade materials after replicating mechanical power.

Unexpectedly, an extremely important item that could only be made by oneself suddenly became a possible consequence that a robot could also make it.

He even designed an autonomous energy system for the robot, so that its energy system can function even if it is completely independent of him.

In addition, the child has updated the robot protocol so that it can learn and evolve independently.

The consequences of these things were not expected by the children.

He just happily followed the appearance of his mother's car in his memory, and carefully and seriously sprayed the robot with the beauty in his memory.

"Di, Xiaodi, there can only be two people in the car seat, and there are only two uncles and sunglasses, what should you do?"

The instrument panel at the front of the car makes a mechanical sound, and the robot checks itself for status data while the child paints it.

"I can crouch in front!"

The child didn't lift his head and carefully sprayed the last area.

"I originally wanted to design it with three seats, because my uncle is not in good health! I'm still young, and the speed is too fast, so Uncle Sunglasses can only drive us! ”

"But after the calculation of the central intelligent machine, I was told that if there are three seats, the speed and stability of the car will have a big impact."

"Uncle seems to be very busy, and every time Uncle Sunglasses runs with us in his arms, I think he should be more speedy, so two seats can ensure that speed satisfies him!"

"I'll just squat in front of the scooter!"

After spraying the last area, the child stood up and looked at the car that had changed a lot with a smile.

Pink hovering scooter.

"Yay!"

The child clenched his fists and bent his arms in front of him, jumping with joy.

Soon, however, his body shook as if he was about to lose his footing.

The child hurriedly held on to the sofa next to him.

After shaking his head vigorously, he said to Xiao Di No. 1: "Xiao Di No. 1, you quickly change back to the previous robot appearance, there are still some materials, you can make some buttons out." ”

"Uncle is probably coming back soon, I'll go make breakfast, and I'll help you change it later."

"Roger!" The mechanical sound sounds, and with a click, the pink hovering scooter transforms into its original four-legged robot.

The pointer on its chest and abdomen emitted a blue electric current, and it began to enter its work quickly.

As time passed, those materials slowly became smaller, and there were more and more dimensional anchor buttons.

In the kitchen, there is also the smell of omelette, steak, and lean porridge with preserved eggs.

The small figure is wearing an apron and stepping on the bench to gently flip the steak.

"How can you just drink protein powder, you still have to eat some meat."

"Grandma said that eating more meat can grow the body, but she never eats meat, and my uncle said the same, but my uncle didn't eat either, hey...... You can't just leave it to me, I'm so young and I can't eat much."

The child muttered, casually turning down the flame on the gas stove.

The pan sizzled as melted butter surrounded the two golden steaks.

Golden sunlight streams through the kitchen window, and the walls reflect the reflection of tiny figures like hair.

"I don't know what my uncle is busy with running out every day and not returning home at night?"

"I've never seen him happy, I've never seen him smile......"

"I hope that the little Di No. 1 given to my uncle will make him a little happier."

"If he can take off his mask and smile, then I've succeeded!"

"Hey, hey, hey."
