Rob carefully used a carbon brush to sweep his joints and absorbed all the water and gas.

As a metal-wood constituent, he can delay the aging of his joints as much as possible.

Since he first saw the same structure, because the experiment was stained with corrosive liquid, causing the body to rust, and was thrown into the alchemy furnace by his master without mercy, Rob has never dared to ignore this maintenance work for a day.

Robu made of gold and wood has been spent 251 years since his birth, and even his master has been replaced for three generations, but he has not yet fallen apart, which is inseparable from his persistent maintenance work.

Unfortunately, his companions will not be able to maintain their care except him, so in the past 250 years, his companions have been updated countless times.

There are more than 60 soul structures like him. All the work of cleaning, moving goods, defending the magic tower, and even laying the bed and stacking quilts are completed by the structure. If the technology of the soul structure is not too bad, even cooking and other work may be handed over to them. His masters are all freaks who wish they could only live in the magic tower.

Rob is a lab-based construct and stays in the laboratory most of the time, so his careful maintenance work has never been discovered by his master. Perhaps his former masters have also wondered why there is always a construct that is cleaner than other ones? But I just wondered, a construct like him is not worth investing too much attention.

Who would have thought that this construct would take care of itself?

After sucking the water, Robu brushed the body with tung oil. Every time he brushed the tung oil, his whole body would be shining, so he also needed to use sandpaper to polish the gloss on the surface to avoid too much change and let the owner discover it.

Since he knew his own specialty, he was very careful not to let others discover it, because all his three masters were curious and very cruel to the construct. If their weirdness was discovered, they would unhesitate to cut themselves apart for research.

After such a life was too long, Rob began to feel annoyed. He stayed in the laboratory every day, facing the bottles and jars that he could tell even with his eyes closed. Such days were so boring.

Sometimes he would think that everything in this laboratory may be more familiar to his three masters. His three masters have performed basic experiments and repeated them two or three times. He could repeat all the processes with his eyes closed.

More than 250 years have been too long. However, he has come up with a way to liberation. If he can succeed, he can always escape from his current life and no longer need to hide it carefully like he is now.

The quiet night passed quickly in Rob's thoughts.

The bright light shone in through a row of small windows on the wall, carrying a warm atmosphere. Rob liked this light very much and quietly took two steps forward to move his body to the point where the light shines.

These lights can evaporate the moisture in his body, kill some invisible things that corrode his body, and keep his body dry. This is also one of the main reasons why he can survive for more than 200 years without decay.

I don't know how long it took, but there was a staggering footsteps outside the laboratory, as if someone was walking with his legs dragging his legs. Hearing the footsteps of his legs, Rob quickly retreated back to his own position by the wall and stood up.

That was the footsteps of his current master. His current master was a sloppy guy. His hair was tied into a ball without taking a bath for many years. The smell on his body could kill flies and mice. He never lifted his feet up but dragged them to the ground. He thought he was a lame person when he walked.

However, Rob didn't care about this. He cared about his master's terrible magic. This sloppy master once took his anger on one of his companions because of the failure of the experiment. The soul structure made of iron wood was also made of iron. After the master's pat, the wood turned into carbon particles, and the iron melted into iron. In the end, the iron block mixed with carbon particles was swept out by Rob.

His three masters are all such terrible magicians who can destroy him with just a slightest palm. Rob, who is very self-aware, never resists his master's authority head-on.

In addition to having powerful magic, the master also has a terrifying guardian.

The door of the laboratory was slowly pushed open, and Sadie walked in irritably. The time spent walking every day made him feel like he wasting his life. Why didn’t his teacher build the laboratory next to the bedroom? Why is teleportation so difficult to learn? Why do people have to walk?

Every time he walked from the highest bedroom of the Magic Tower to the lowest laboratory, Sadie was filled with similar resentment. In his concept, everything except experiments was a waste of time. It would be great if humans did not need to eat, sleep, or excrete.

Thinking of this, Saidi glanced at the components standing on the wall with resentment. All these time-wasting activities he hated were not needed.

Huh? Saidi's eyes stopped on Rob's body. Although Rob was careful not to change his appearance, the difference was still very obvious compared to his companions, and his body was very clean.

Among the dirty and dirty people, his cleanliness is so obvious.

However, it seems that there is always a very clean construct here. Sadie just took a look at it and stopped paying attention. Each of these constructs in the laboratory looks exactly the same. Sadie himself can't tell which one is new and which one is old, so it's natural that the cleanest one should be the latest one, right?

It is indeed difficult for a soul constituent to attract his attention. Today's experiment is the most critical.

The preparations yesterday were completed, and all the materials and equipment were placed. However, because the reaction time of the entire experiment was very long, in order to have more energy to deal with the experiment, Saidi decided to postpone the experiment until today, so that he could sleep well before proceeding.

The long table of the experiment was filled with bottles and jars, and the reaction circuit and magic furnace were all full. The reaction kettle was filled with some white crystals. Just wait for him to pour the liquid from the glass bottle into the kettle, and the entire reaction process would begin.

This is an experiment supported by countless experimental data and is very low in danger. With strict protection in his mage tower, Sadie's vigilance is completely zero. He picked up the bottle and poured the liquid into the kettle.

As soon as the liquid touches the white crystals in the kettle, it is like water dripping on the red iron plate, and a strong smoke suddenly rises, with a little blue color in the white.

The blue white smoke..., the smoke without any smell made Sadie feel a bad feeling and immediately held his breath.

But it was too late. The rising smoke rushed to his face immediately, and a large mouthful of smoke rushed into his nose. Then, a hot feeling spread from his nose to his lungs, and the whole lung was about to burn.

The severe pain caused him to spasm all over his body and he sat down to the ground.

Thick white smoke filled the entire laboratory.

The white ones mixed with cyan ones will react violently with the liquid... Sadie's face was ashen, and he thought of something that was also white crystalline - the tears of the angel.

This white crystal with a beautiful name is essentially one of the most poisonous substances in the world. One gram of angel tears can poison more than a dozen giant elephants, and the reaction speed is very fast, and it can kill in three seconds. There are at least two or three hundred grams in the reaction tank, but he sucks in a big mouthful.

Who changed the material in the reactor to angel tears?

Before he could think about this problem, his consciousness began to blur.

Behind him, a figure appeared and two short blades shining with cold light were held in their hands, vigilantly searching for the enemy.

Rob's heart moved slightly, and this looming figure was the master's guardian, a shadow structure.

This shadow structure is a combat structure with very strong invisibility. Without taking action, even if it stands in front of you, it will be difficult for the enemy to discover its existence. Moreover, the shadow structure has high martial arts skills, no emotional or physiological needs, will not relax, and has strong perception. It is the best guardian.

With a shadow structure, even a squad of human soldiers cannot hurt the master at all.

However, no matter how powerful the shadow structure is, it must be found to play a role. The question is where is the enemy now?

Shadow construction has maximized its perception ability, but searching throughout the room, there is no object that can be included in the category of enemies.

Sadie's consciousness became blurred, and his body began to twitch instinctively, spitting out white foam from his mouth. After struggling for a while, he stretched out his legs and hung up.

The highly alert shadow structure appeared, and the light gradually weakened in both eyes that were transmitting red light. After a while, it completely stopped operating as if it had lost its energy. At the same time, a black gem ring on Saidi's hand also flashed a ray of light and then completely extinguished.

The shadow structure is a guardian structure and is associated with the master's life breath. When the master is dead, there is no need for protection, and the shadow structure has no value for existence.

Rob stood quietly, rotating day and night, until Sadie's body began to get hard, he started to move.

He walked slowly to Saidi, gently took off the black gem ring from his hand and put it on his finger. Then, Rob moved his hand with the ring to his forehead and printed it with his own consciousness.

A ray of light flashed on the black gem, and the extinguished light in Shadow Mechanical eyes lit up again, and the figure melted into the air again, Shadow Mechanical was activated again.

Rob felt a wonderful connection between himself and this shadow structure.

But this wonderful connection lasted only half a second, and Rob felt dizzy and the connection was interrupted.

The shadow structure melted into the air reappeared in the body, and then the body began to twist and retreated to the middle. After a while, it shrank into a fist-sized sphere, which scared the ground with a jingling sound.

This is the native state of shadow construction.

After staying in the laboratory for a long time, Rob, who was influenced by the eyes, also learned a lot of miscellaneous things. This situation now means that his mental power is not enough to drive the shadow structure.

The construct is made by the constructor. In order to prevent the backlash of the construct, the manufacturer has set up preventive measures during the manufacturing process. When the backlash occurs, the preventive measures are activated to restore the construct to its native state.

This means that Rob cannot control this powerful guardian.

Rob didn't feel sorry, the shadow construction was just included, and his real goal was on this ring.

The black gem ring of Saidi is his most precious treasure. This ring not only controls the mark of the shadow structure, but also is also the key to open all restrictions on the Magic Tower. Without this ring, even the door lock cannot be opened. If it is forced to open, it will inevitably be counterattacked by various restrictions.

In addition, this ring is also a storage ring. The wealth accumulated by three generations of Saidi and Saidi’s teachers and apprentices are hidden in the ring. It can be said that getting this ring is equivalent to getting all the wealth of a magic tower.

However, as a constituent, Rob did not understand the value of these wealth. He opened the storage space, looked through for a while, and finally found a pile of magic crystals inside.

The constructs do not need to eat. The energy provided to them with activity is these elemental crystals, something that magicians call magic crystals. This is Rob's favorite thing.

There are more than 1,000 first-level crystals in the storage space, more than 500 second-level crystals, and only one hundred above level three. The most advanced one is a level six dark magic crystal.

The magic elements contained in each level of magic crystal are also different. A non-combat structure like Rob can provide his three-month activity energy. If he is dormant for most of the time, it will last longer.

Rob last changed the magic crystal half a year ago, but because he needed to maintain his body, his activity time was much longer than his companions. He often consumed the magic crystal, but his companions did not consume it.

Because the consumption is too fast, it will be used up every time before the date of replacing the magic crystal. If there is no magic crystal, he will not be able to move. However, he is not the stupid kind of person, just switch the magic crystals of his companions to himself.

So every time a similar person consumes magic crystals in advance. For this issue, the masters of the three generations have been puzzled for a long time, and even split up several of the unlucky similar people to study. Naturally, the reason cannot be found, and the matter ended up being left alone. If they want to break their heads, they would not have thought that there would be a construct that would move around.

But from now on, Rob doesn't need to be so careful to live anymore. The entire magic tower belongs to him. After having the ring, he can enter any hidden place at will.

For the first time, Rob walked so casually in the Magic Tower and walked up the stairs one by one. Finally, Rob came to the highest level of the Magic Tower, which belongs to the bedroom of the three masters.

When his footsteps kicked up the last step, a faint wave faintly swept across him. When he swept over the ring in his hand, the ring immediately gave back another faint wave.

Squeak, the heavy wooden door facing the stairs slowly opened.
