Since it is a defense mechanism, it is impossible for the great people of Halis not to prevent this situation of being besieged in their homes, so whether it is the solubility of the ground metal and the absorption of energy attacks, it can keep those impregnable defense mechanisms running, until thousands of years later, these materials may fail due to a long lack of maintenance.

The "clucking" rooster-like cry quickly interrupted Rick's thoughts, and he opened his vision along the source of the sound, and suddenly a cold frost appeared in front of him.

A large number of human batteries rippled in the cold frost, and the short columns engraved with frost patterns were inserted all over the body, and a large amount of cold air continued to emerge from the short columns, increasing the area of the entire frost mist and maintaining the storage environment of those giant hyenas.

"Oh, it's a giant hyena?" Rick looked at the group of giant hyenas coming in and out of the frost mist, and a hint of doubt flashed in his heart.

It stands to reason that at this stage, this kind of giant hyena that is not even a first-order has been eliminated, but seeing this creature at this time, Rick actually has a somewhat familiar feeling.

However, if you think about it carefully, the manufacturing process and waste of materials for giant hyenas should be cheaper and easier to find than red-faced hyenas, so in this way, it is more cost-effective to use giant hyenas to explore the way.

In this way, both the consumption and the cost are reduced to the lowest level, and Rick also noticed that these giant hyenas are barely covered with any cold steel, so that the cost is reduced again, almost equivalent to the cheapest cannon fodder.

These giant hyenas are indeed exercising the very honorable profession of cannon fodder. They are not afraid of death, they are not afraid to move forward. It's just that he keeps consuming that pitiful little bit of energy with his life. Said that he contributed his meager strength.

Looking at the area of frost and mist that was almost connected to the mouth of the passage. Rick knew that there must be a large number of lackeys in these Galactic Heavens, but looking at the situation at this time, it is estimated that even if they are all consumed, there will be no breakthrough.

Rick found that the corpses of the giant hyenas that had died in the attack range would be quickly digested by an inexplicable pale green mist in a very short time, constantly replenishing the consumption of these defensive weapons.

So in this way, this is not only not an act of consuming those defensive weapons, but an act of delivering food to the other side. But according to the cunning Cheng of the Milky Way and those Tali tribesmen, it shouldn't be comparable to this? Do they have anything else in mind?

Really. After a few hours of observation, Rick finally discovered the main purpose of these mashups.

It turned out that they had already discovered that these dead corpses were a kind of almost complementary thing for the weapon systems that defended the room, so the giant hyenas they sent out said that they would attack those ground frantically when they were dying, and the corner of the ground was the place where the pale green mist was released, which had been a little tattered by the death-threatening blow of hundreds of giant hyenas.

This very time-consuming, and very resource-consuming, behavior was eventually reported. Without those pale green mist to replenish energy, at the same time that hidden digestive system was destroyed. These weapons systems are doomed.

After all, it is a human being, and it is impossible to lose to the machine.

Rick had been waiting, not believing that these guys had the energy to open up all the rooms in a matter of time.

And the original plan also needs to be changed, the original plan of Rick was to open all the rooms and then find something valuable to take away.

But the situation at this moment made Rick understand that he couldn't go room by room, he didn't have that much time and opportunity, and he had to make a choice.

The city is huge, but at least more than 90% of the place is ordinary people's houses, and the rest are some government agencies, such as research institutes, material warehouses, hospitals, administrative offices, etc.

After two days of careful observation, Rick had been keeping track of how long it took for the giant hyenas to breach a room and how much time they had rested.

With the continuous in-depth understanding, Rick Discoverer and these guys are actually slowly learning, increasing the time to crack the ordinary Min Jianghu, which originally took a whole day to crack and break the behavior, now it only takes half a day.

Determining the rest time for these giant hyenas and those mermaid sacrifices, Rick immediately went into action.

It was almost impossible to distinguish between night and day, but the merfolk sacrifices seemed to need more than four hours of rest every twelve hours to replenish their consumption and energy to release these frosty aura.

Rick only had four hours left to get as much of the items in the precious room as he could.

Rick didn't know if he would be found out right away, so he could only try to reduce the search range and the number of rooms.

If you're unlucky, you may not have a chance after the first time, so Rick has to pick and choose a more valuable room to search.

To be honest, the continuous observation of the cult of the Galactic Heaven in the past two days has made Rick lose the idea of starting with them immediately, because the foundation of the Galactic Heaven is too deep, even if the materials consumed by those giant hyenas are very cheap, but the consumption of the whole day has reached an astonishing thousands.

It's no wonder that the remnants of Hellis are reluctant to try to crack these rooms even if they discover this secret, the population is just their weakness, so it is really a bit worth the loss to spend thousands of lives to open a place that may be a private house.

By the time they had breached another dwelling, the guys had begun to rest.

Rick didn't delay, and sneaked straight to the most luxurious and well-equipped government office building.

Compared to the rest of the world, it was clear that the tallest building should have something of value in it that Rick wanted.

With some means, Rick quietly entered the office building.

It's a very large area, almost as tall as a ten-story building, and it's filled with plenty of private rooms.

Rick couldn't search every room, so he had to pick up the important ones and take a look.

Soon, in the room on the ground floor, Rick found a lot of good things, but almost all of these gadgets were lost and could only be used.

Some of the gadgets that Rick wanted to take with him, and then made his way to the higher floors.

There was a very slight "click" in front of Rick, and it was so quiet that even a very slight noise could be heard and noticed.

Rick immediately turned into an alien orc, and the ice pillar behind him also reached his hand, activating the "Ice Ingestion" and saying that he could attack at any time.

After waiting quietly for a while, no sound came, but Rick knew that it was definitely not his auditory hallucination just now, so his nerves were tightened, ready to fight at any time.

"Ice Touch" accompanied by Rick's low shout, and bursts of surging ice breath extended out like tentacles, which was a simple control behavior after Rick incarnated as a xenomorph orc, and the extension of Rick's cold breath could increase Rick's perception and observation of the surrounding environment.

The distance of the Ice Touch is not very far, because now Rick has just been promoted, and he is not very good at controlling the body of the incarnation, when after a period of time, Rick can completely control his own body, then Rick will be able to explore and observe from a distance.

So now I can only make do with observing some of the surroundings and movements.

But it's a pity, as if it appeared suddenly, there was nothing in the place where the movement was made, only a few die-hard machines that were still shining with metallic luster stood quietly in the corner, silently enduring the precipitation of time.

Rick maintains the state of incarnation, and continues to look for things that have a little value, but the good luck seems to have run out last time, basically some daily necessities and personal items, and many useful things are equipped with an identification system to prevent theft, even if Rick gets these things, there is no way to use them, because these things have been bound to their master's body and genes, unless they themselves release this binding or are unbound by the government after death. to allow others to use these things.

But the time of the disappearance of the Hellis Empire was too rapid, too sudden, and it didn't give those people time to react at all, because because of their sudden disappearance, the entire empire was almost reduced to the world of those machines.

The city was able to survive reluctantly, not because of how good the defenses were, but because it was also mechanical, so the mechanics were not interested in buildings with no signs of life.

So even if these defenses are not hungry to really defend against the invasion of those mechanical bodies, but because they are of the same kind, they did not deliberately destroy these buildings, otherwise this place would have been in ruins a long time ago, where would it be Rick's turn to explore?

"Snap"

While Rick was looking for something, there was another strange noise, and this time Rick reacted very quickly, stepping on the ice in an instant, and suddenly came to the location where the sound appeared.

It's strange that there's still nothing.

Rick carefully observed the surrounding environment and movements, but there was still no discovery, no traces, no footprints, not even breath fluctuations in the air, what a strange thing

Although thinking so, Rick did not stop his search for this government building, because after finding that there was nothing of value on the ground floor, Rick began to go directly to the upper floors, because the upper floors are basically where those with more status live and work, so there should be some good things left.
