There was no one on the road, and of course, Qi Feifei would not go to find someone's way.

Soon after escaping from the hospital, the three of them turned into a tree-lined path, if they took the road at the entrance of the hospital, even if Qi Feifei's field was paved, they might be seen from a distance, of course, it was not as safe as coming up on the grove road, once they found someone, even if they couldn't dodge, at least they could squat down and pretend that they didn't exist, which was also a kind of buffer.

Speaking of which, this is the first time to leave the post-paved realm of the hospital, Qi Feifei somewhat understands what the characteristics of her own realm are, such as the fact that only one building can be constructed at a time, and if there is no building, then it is an area with itself as the central point. So in the hospital before, the field could not be built outside, but now in the forest path, the field can not be built in three dimensions, but can be spread out over a wider area, like a radar, where there are living people can detect the footprints, Tibetan cats are super easy to use.

There is also the size of the field is related to mental power, for example, she didn't sleep well yesterday or today, so her mental attention is not concentrated, the construction of the field is slow, the lines are scattered, and for example, ...... If you run out of mental energy, you will be tired, or ...... Die.

Compared with other personalities who were swept away by Senior Brother Zhang's stick, Qi Feifei never thought that it was Chai Yancheng who fell first.

Because among all the people, he was the only one who had been using the Realm Broken Window Effect, so in the end, the first one to die was him who had exhausted his mental power.

It is not quite right to say that it is qi, to be precise, it should be the exhaustion of mental power, resulting in brain death, and the death of the brain leads to the termination of various functions of the body, so people naturally die. Although other people will not die directly like him, they will also fall into a deep sleep because of the excessive use of mental power, and if they can't wake up like this, they will probably be in a vegetative state.

The reason makes sense, but Qi Feifei also knows for the first time that mental power exhaustion is such a way to die, thinking that he was fine before he spread his mental power in the 22nd floor underground of the hospital, Qi Feifei was really worried about whether he could see the sun tomorrow at this time.

Because of this, Qi Feifei shrank his field as small as possible, so that once they all heard the footsteps of other people outside the woods, and it was not clear whether it was a returning soldier or a deserter from the martial arts club, but fortunately, the place where the sound came from was a long distance away from this tree-lined path, and after squatting, there was no other sound, and it seemed that the person had left.

"You can eat it." Mo Huating said affirmatively. "Otherwise, how do you think the level of the Adept will be raised? There are two ways to improve, one is to keep using the ability, and after using it up, rest enough to recover, just like the rising tide, every time the wave hits up, retreats, and retreats to accumulate ability, when it hits up again, it will be farther than the last time, but this method of improvement is really slow and ruthless, so in fact, the main way to improve the level is the second method, which is to eat the crystal nucleus, but not all crystal nuclei can be eaten, and not all people can eat crystal nuclei. ”

Classification of crystal nuclei.

The first is an ordinary crystal nucleus, produced by ordinary zombies, colorless and transparent, in the context of the end of the world with crystal nucleus as the main currency, if you don't waste it, you have to punch holes in it and use it as a prismatic bead to wear the curtain, it's not a problem, it's quite beautiful.

PS: This nucleus is inedible because it doesn't contain any energy.

The second is the ability crystal nucleus, as the name suggests, zombies with abilities will produce this crystal nucleus, the difference is that this crystal nucleus has its own color, the five elements are divided into five colors for the time being, and other types such as the five senses series, the gossip series and the body strengthening series of abilities, all have their own colors, and each ability can only be upgraded by absorbing their own series of ability crystal nuclei.

PS: If you take the wrong ability, it will be like taking the wrong medicine, the light one is spending money in vain, and the heavy one is not without being directly taken into the ICU for serious illness, but because some of the ability crystal nuclei are really hard to find, so it has also derived the industry of crystal nucleus staining......

By the way, once the ability crystal nucleus is absorbed, it will revert to a colorless and transparent ordinary crystal nucleus, that is, the so-called eating is only the ability contained in it, as a one-time supplement, once it is absorbed, there will be no more, so the value of the ability crystal nucleus is more than a hundred times higher than that of ordinary crystal nuclei.

So it's also troublesome to want to upgrade your abilities in the last days, just like an actor, or you will go to the strength of the acting school, purely by fighting monsters to upgrade, but this is accompanied by the danger of running out of abilities from time to time, and it is easy to level up in the early stage. Otherwise, you will go to the idol faction and rely on spending money to absorb crystal nuclei to get to the top, which is safe and fast, but the cost is too big and it is difficult to continue in the later stage.

Of course, the best way is to absorb crystals in the early stage and upgrade in the later stage, but this can only be done with wealth and status, and ordinary people, in the case that all their savings are in vain before the end of the world, and they can't even eat enough, they can only fight monsters desperately.

But ordinary people fight monsters, at least there is a chance to level up.

The spiritual department is an exception.

It can be said that the spiritual system is always an exception to humans, even zombies.

The spiritual system cannot be upgraded.

"This matter has been discovered in the early days of the end times, and other abilities of various systems, even very rare abilities such as clairvoyance and downwind ears, can absorb abilities as long as they hit zombies of the same lineage, but the spiritual system cannot be upgraded at all. On the one hand, because everyone's mental power is limited, it seems that the doomsday virus cannot strengthen the characteristics of the spirit, and on the other hand, it ...... It's because there's only one known spiritual zombie. ”

This doomed the spiritual system to be unable to upgrade by using abilities, nor to absorb crystal nuclei to upgrade.

Qi Feifei always felt that the spiritual department was like a motherless baby, not to mention that the human side was not good at mixing, but I was afraid that when it came to the zombies, the mix would not be satisfactory.

"So...... You called me because ...... Are you sure this zombie is a psychic? ”

Qi Feifei understood what Mo Huating meant.

In the past, there were too few zombies in the spiritual system, and the second upgrade path was completely blocked, but now, there are several known zombies in the spiritual system, which proves that at the beginning of the last days, there are actually a lot of zombies in the spiritual system, with zombies, there is a crystal nucleus, and the spiritual system also has a way to upgrade, Mo Huating specially called Qi Feifei and the three people to come up, just to let her and Mo Yuanshan try the crystal nucleus of the god system?

Then why doesn't he eat it himself, isn't he also a spiritual department?

Qi Feifei only regretted coming to Mo Huating's side first at this time, if she returned to the base villa first, the worst outcome would be that Xingyuan would give her a good time, but Mo Huating is a person who loves to do research experiments, and it was her turn to upgrade the spiritual crystal nucleus. There can't be any conspiracy, right?
