The advantage of the magic barrier is that as long as the six crystal cores are not damaged, the barrier can always be maintained. And the more energy there is, the stronger the barrier will be and the wider the coverage will be. However, if the attack is stronger, the energy will

The faster the stone is consumed, once it exceeds the endurance limit, the energy will backfire and the core will rupture.

However, there is a way to avoid the risk of core rupture, and that is low consumption.

Just one energy stone at a time.

Because when there is insufficient energy, even if it suffers a powerful attack, the energy backlash will be weak and not enough to break through the six crystal cores.

The downside is that the barrier's solidity and coverage will not be very strong.

But Luo Yi considered that at the end of the world, there will be a very unstable energy storm. Once it breaks out here, it will directly destroy the crystal core and waste this magic barrier, so he can only make the magic barrier into a low-cost one.

model.

Moreover, in the early stage, as long as you can resist the evil energy emitted by the black rain, you can easily use the earth's machines in the building, and you can block most of the weak entrances to prevent monsters and survivors from sneaking in too frequently. In addition, there are three battles

The robot is responsible for patrolling and preventing fish from slipping through the net. Once the logistics robot repairs the monitoring equipment, there will basically be no big problem.

…

"Follow me."

After setting up the magic barrier, Luo Yi took two logistics robots to the bottom floor of the building, where the main power switch for the entire building was arranged, as well as a set of backup power supply facilities.

During the period of the doomsday outbreak, the power supply is intermittent and becomes very unstable. With the continuous erosion of evil energy and the outbreak of energy storms, facilities ranging from power stations around the world to civilian power lines will be completely damaged, and the power supply will

In a long time, it has become a rare energy source.

The energy converter exchanged by Luo Yi is used at this time. As long as there is energy stone, there will be no shortage of energy, which can be directly converted into electrical energy to provide the use of electrical equipment in the building.

"You come here once a month to place the energy stones."

After Luo Yi explained to the logistics robot, he placed a square mechanical box on the main power switch, put in an energy stone, and pressed the start button.

Soon, the mechanical box spread out into a precise and transparent streamline, like water flow, and began to permeate the main power switch, covering and infiltrating the backup power supply facilities next to it.

At this time, the energy converter is absorbing the remaining electrical energy and converting the energy into the same energy source.

"It should be fine."

Seeing that the energy converter was working normally, Luo Yi stopped staying and returned to one of the floors upstairs with two logistics robots.

As far as the eye can see, this floor is full of rows of bookshelves with various books stored on them. At the same time, at the deepest part of the floor, there is a batch of computer equipment.

"Your task now is to learn the knowledge here."

Luo Yi pointed to the computer equipment next to him and said: "After you finish studying, use those computer equipment to set up a local area network, repair the building's internal monitoring, make an automatic alarm system, and then make weapons..."

After issuing a lot of instructions, Luo Yi allowed the two logistics robots to learn on this level.

After all, logistics robots are intelligent machines created by advanced civilizations. As long as Luo Yi does not develop any high-tech items, logistics robots can definitely be competent in various tasks through learning, and can even do them more accurately and meticulously than humans.

…

"With this arrangement, the impact of the end of the world on me will not be too great. Once I obtain the status of 'Infinite Player', I can go to other worlds to obtain resources, build a truly fully functional base, and gather the remaining human beings."

, implement some of my ideas..."

Luo Yi returned to the fifth floor while thinking about what would happen in the future. When he saw the body of the goblin locked in the cage, his thoughts returned to the current matter.

At this time, the goblin's corpse turned very dark, as if covered with a layer of ink, exuding wisps of turbid aura. From time to time, something was crawling on the skin, and from time to time it was twitching violently.

"Well, it's almost mutated. But the level of the goblin is too low. It mutated into an undead goblin. It only has a low-level dark core, which is not enough."

Luo Yi took out a metal test tube from his pocket, which contained the psychic blood obtained from Xu Shengli, as well as a very domineering blue spirit potion.

Then, he came to the workbench and extracted one-third of the blood inside. The deep red blood had traces of dark blue sparks flickering.

"With this special blood, after the goblin mutates, will it condense a higher quality dark core?"

Luo Yi injected blood into the goblin's corpse, not worrying that this reckless behavior would cause the goblin to go wild, mutate, and lose control.

Because after the injection, he pulled out a large mechanical crossbow placed in the corner.

The heavy and huge mechanical crossbow is equipped with a fixed mount, like a fort, and is aimed at the Goblin in the cage. Three metal crossbow arrows are placed on the crossbow. Each crossbow arrow is as thick as an adult's arm.

, once hit continuously, as long as it is flesh and blood, it will be penetrated or even broken into two halves.

"How far can it mutate? - Blue Spirit Potion, don't let me down."

Luo Yi didn't think that just a little goblin could make him overturn his car, so he didn't bother to go upstairs to get the equipment. If the goblin really lost control, it wouldn't be too late to call the combat robot to stop him and get the equipment again.

Less than a minute after the injection, the goblin's body underwent drastic changes. A large number of dark blue spots appeared on the dark skin, and patches of dark blue fine scales were forming...

"hiss--"

Suddenly, the Goblin opened a pair of dark blue eyes, grinned with fine fangs, and let out a sharp and piercing scream. His skinny body swelled in a large circle, and he rushed towards him violently, pulling the chains to rattle.

ring.

"That's it?"

Luo Yi frowned, not very satisfied with the degree of mutation of this goblin. Although it seemed to be more energetic than the average undead goblin, it was not fierce enough.

"Is it because the goblin's potential is too low, which limits the effect of the blue spirit potion?"

While thinking about it, the mutated goblin's blue spots became very dense, and he frantically tore at the iron chains that restricted his body. A stream of hot light blue smoke burned in the goblin's hand.

"Hey, this is...not good!"

Luo Yi noticed the abnormal temperature emanating from the goblin's body, and at the same time he noticed a wisp of light blue smoke coming from him. As he breathed, he suddenly felt a strong sense of dizziness, his heart beat rapidly, and he immediately knew what was going on.

He reacted very quickly, pulling off the tactical helmet still on his head, opening the gas mask and turning on the ventilation equipment.

"Is this activating the toxin in the goblin body? Well, it also increases the intensity of the evil energy, resulting in an abnormally high temperature..."

Luo Yi saw the thick iron chain showing signs of twisting in the hands of the blue-spotted Goblin, but he also saw that the Goblin's swollen body was drying up at a speed visible to the naked eye. It was obvious that

There was no energy in the goblin's body, there was not enough evil energy, and it was a corpse. It was quickly drained by the blue spirit potion, and the backlash began.

Less than a minute later, the goblin who had just mutated into the undead type died again, and this time he could not die anymore. He was directly turned into a pile of light blue ashes by the dark blue potion.

"..."

Luo Yi suddenly thought of a question. The Blue Spirit Potion was so overbearing and drained the goblins dry. Doesn't that mean it couldn't condense the dark core?

I thought there was a high chance that it was gone, but when I peeled away the ashes, I found a dark blue crystal core lying quietly inside.

"Can this... be used?"

Luo Yi picked up the dark blue crystal core in front of him and wondered whether it could be used as a normal dark core.

Because to synthesize the true universal evolutionary fluid, a dark core must be used as a blender, otherwise he would not make goblins into undead monsters in order to condense a dark core.

But now this dark core has obviously changed, and it most likely contains the overbearing effect of the Blue Spirit Potion. If it has no side effects and will not be affected by the orthodox bloodline of the Nether Clan, it is naturally a rare evolutionary substance.

As for whether it can be used as a blending material for the 'Universal Evolutionary Fluid', that is unknown.

"I can only find the Chaos Spirit and do a test. Well, when I exchanged things, I should have exchanged them for a high-level dark core as a backup..."

With Luo Yi's vision, he can naturally see that the value of this dark blue crystal core must be greater than that of a low-level dark core, and it is not even possible to condense such a mixed substance every time.

The dark core itself can only be condensed by monsters that have absorbed a large amount of evil energy. Moreover, the dark core is a pure evil energy substance that can be transformed into a life substance suitable for human consumption as long as it is integrated into the blood. Therefore, it will last for a long time in the end of the world.

, this is the way for non-players to become extraordinary.

Luo Yi considered this direction of thinking. Does this dark blue crystal core also contain pure evolutionary substances? It has filtered out the side effects of domineering and blended with evil energy. Can it be taken according to normal procedures?

But he was not sure, and he couldn't help but have a more urgent need for knowledge. If he had some knowledge of alchemy, medicine, or biology, he could naturally analyze the information and there was no need to find the spirit of chaos to do this test.

Of course, the so-called finding the Chaos Spirit actually means going to Xia Meilin. Only official players can contact the Chaos Spirit.

…

At this time, Luo Yi came to the second floor and knocked politely on the door. Suddenly, there was a flurry of panicked movement inside.

After about a minute, the door opened, and Xia Meilin's charming white face poked out. Under her beautiful eyebrows, a pair of clear and bright water eyes, like blue waves.

"Are you here to visit Lilith? Don't worry, she's fine..."

Xia Meilin blocked the door, obviously not wanting Luo Yi to come in now.

"inconvenient?"

Luo Yi asked very directly.

"..."

Xia Meilin's pretty face stiffened for a moment, forgetting that this guy was a straight man. She rolled her eyes at Luo Yi in annoyance and said, "We are going to take a bath. Do you think this is convenient?"

"oh."

Luo Yi ignored her eyes and words, took out the dark blue crystal core, and said, "You should have kept the points, right? Help me inquire about the Chaos Spirit, this thing."

"You are so rude."

Xia Meilin looked helpless, took the dark blue crystal core, and asked curiously: "How did you know that I kept the points?"

"..."

Luo Yi gave her a meaningful look and did not answer.

"If you don't tell me what your look is, I won't tell you."

Xia Meilin raised her eyebrows playfully, then connected to her personal system and sent a request for consultation service to the Chaos Spirit.
