Zheng Wei, as always, did not question Liao Yu's decision, but silently monitored both ends of the crack in case a monster approached quietly.

"I can't tell where those monsters are from the sound, but at least they're not in the cracks in front of you." Liao Yu stood up on his own against the wall. "We're rushing out now to gamble that we won't run into them, and if we do, I'm bound to be a burden to you. Instead of this, it is better to stay here and recover, I feel that the potion is still effective. ”

"Also...... I'd also like to take a look below. ”

Zheng Wei understood what Liao Yu meant, and Liao Yu still felt guilty about the dead people. He had no objection to this, and helped Liao Yu to the edge of the crack and climbed down, and finally stopped at a platform about five meters above the ground.

In addition to the traces caused by the earthquake itself, there are also traces left by many skeleton monsters when they rushed out of the ground. And for the two of them, who are both more than one meter and seven meters tall, the climbing claw marks left by those monsters that are more than ten meters long are spacious enough. The platform had apparently just been used as a foothold by a massive skeletal monster, and a depression of more than a meter deep enough for the two of them to squeeze in, avoiding the view from above.

During the whole process, Zheng Wei only quickly swept the nearest cliff with a half-covered flashlight at the beginning, and after determining the place to stay, the two of them did not turn on the flashlight again during the whole process, and climbed completely by relying on memory and the touch of their hands. By the time they stepped on the platform, they were both sweating profusely.

After Zheng Wei helped Liao Yu take off his soaked coat, he sat on the outside of the platform alone holding the broken armor. In fact, from the time he returned to the research institute to the present, compared to Liao Yu, who has always been releasing magic such as swift power, fireball technique, and primary lightning, so that the magic power is exhausted, Zheng Wei has not lost much strength in the whole process, except for the small injuries in the spiritual world when the skeleton warrior was destroyed at the beginning.

The crawling sound in the ears of the two of them had faded away, and it seemed that the two of them had been given a short time to safety. Zheng Wei stared at the dark crack in front of him like an abyss in a daze, and suddenly whispered "!" after a while, he suddenly whispered, "!" ”。

"What's wrong again?"

Liao Yu asked softly, but his eyes did not open.

"It's nothing, I just feel that I followed you here for some reason, I feel like I want to save you, why did I put myself in it instead."

Zheng Wei said helplessly, Liao Yu just smiled and didn't talk.

"Hey, but aren't you meditating? Can you still talk to me without fear of any problems? ”

Zheng Wei's concern is not unreasonable, according to the traditional way of meditation, the magician should devote himself to meditation, in this process, it is difficult for the magician to respond to the movement of the outside world, which is why most of the magician's residences have many means of defense such as magic arrays.

The spiritual world parallel to reality is not safe, whether it is from the various magical knowledge that has been obtained, or the traces left by some mysterious magical creatures that Liao Yu has vaguely noticed, this view can be confirmed.

In Carl's opinion, even for the great magician, the spiritual world is an extremely dangerous place. Because for most mediocre magicians, they can't distinguish the difference between soul and body, and can't separate it well, which leads to the fact that once they want to manipulate the body to react to the outside world, they will inevitably shift most of the soul's attention to the body. In order not to let the spiritual power suffer accidents in the spiritual world, they naturally had to interrupt their meditation.

Only when they reach the magister or above, or when the soul power is extremely strong, the mage can use a method similar to splitting the soul, leaving a part of the soul and spiritual power in the body to manipulate the body to make some simple reactions, as for the doppelgangers such as demigods and lichs, in fact, the principle of their essence is almost the same.

However, Liao Yu got a glimpse of another way from the knowledge given by Hantang and the magic notes of genius Karl, of course, he was not strong enough to split the soul into a small part, but he found that perhaps because of the previous encounters, he had a much easier control over the matter of separating the soul and body than he imagined.

Liao Yu can use his spiritual power to manipulate his soul body to capture all kinds of magical elements in the spiritual world, and at the same time, he can also distract himself from manipulating his body to do some simple things, and he can even make actions such as eating and writing during this period.

Of course, this is not without drawbacks, and the efficiency of Liao Yu's meditation is not even one-tenth of the effect compared to when he is engrossed.

After Liao Yu gave Zheng Wei a brief explanation, Zheng Wei naturally closed his eyes and tried it, but he quickly shook his head and said that it was not feasible at all, obviously this method is not a universal method that everyone can use.

"According to the experience you said, if there were no cold ponds, any ordinary magic apprentice would almost definitely die after experiencing the encounters in your first two worlds, and there is no way for you to replicate this way."

After a little thought, Zheng Wei quickly found the cause of the problem.

"I just want you to try it, and I'll lend you that notebook when I go back, and you can see it too."

Liao Yu was not surprised by this, and any valuable conclusions were summed up by the succession of countless ancestors. To want to whimsically and suddenly arrive at a conclusion similar to a fundamental theorem is in itself a blasphemy against science.

The two fell silent again, and Liao Yu continued to use this inefficient way to accumulate magic bit by bit.

The dead and dark environment is easy for an impatient person to go crazy, but fortunately, although Zheng Wei often complains a lot, he has never lacked patience, otherwise he would not have cultivated to the top level in the professional field at this age.

Time passed, and there were two heavy and rapid sliding sounds overhead, but fortunately, they didn't reach the point where they needed to press the trigger for armor piercing.

It wasn't until Liao Yu recovered his little magic power that he finally opened his eyes and patted Zheng Wei's shoulder.

"Let me take a look around first."

In Liao Yu's spiritual world, there were no other soul fluctuations around twenty meters or so, which at least meant that there were no skeleton monsters squatting there directly above their heads for the time being, waiting for the two of them to emerge from below.

"Lend me a flashlight."

Zheng Wei stretched out his hand and handed over the flashlight, Liao Yu reached out and blocked the front end of the flashlight with four fingers, and adjusted the brightness of the flashlight at the same time, so that the flashlight only had a very low brightness slit pouring out of his palm.

Liao Yu used this light slit to carefully sweep towards the place where the skeleton monster on the right rushed out, the flashlight produced from Liao Yu's era was of extremely high quality, and the brightness could be guaranteed to be stable even from dozens of meters away.

With the help of this light slit, the two of them could clearly see the countless huge claw marks that crisscrossed and crisscrossed below, and from this size, only the skeleton monster leader could match it. And around the mountain wall, Liao Yu also found a lot of obvious artificial traces, some of which were hanging on the mountain wall The wreckage is very much like a part of some kind of fortification, not a simple tunnel project, obviously for the underground things, Chu Fei and they know far more than they show.

For the sake of safety, Liao Yu did not dare to continue to shine the light directly into the depths. However, the silhouettes of those cavernous black shadows that faintly revealed from the depths of the crack were obviously almost hollowed out by these skeleton monsters a little bit.

"You see, these traces are obviously not made in a day or two, without your plan, these people will not only die, maybe even more, don't forget, the earthquake has never stopped since we came in, until now."

Zheng Wei's cold words were unceremoniously inserted into Liao Yu's guilt.

"I don't kill Beren, but Beren dies because of me."

Liao Yu whispered this, and then put away the flashlight.

Liao Yu didn't know what experiments the lab would do with the hatchlings they sent back, but it was clear that the experiments they did would greatly affect the reactions of the skeleton monsters underground.

According to the other two mission methods proposed earlier, Liao Yu was able to speculate that because the three of them handed over the hatchlings at night, and the power system was not paralyzed, these underground monsters would delay the time to rush out of the ground. And these monsters will attack the research institute first, and when all the attention of the research institute is used to resist the Polo spider queen and the dinosaurs, the skeleton monsters will break through the mountain under the stimulation of the movement outside. At this time, the Third Institute of Humanity was not prepared for this, and at that time, the truly deadly horror of the message of the mission holding out for twenty-four hours had just begun.

So what Zheng Wei said was not wrong, under the catalysis of the two conditions of the early return of the larvae and the sudden and temporary interruption of electricity, the skeleton monster hovering near the gap in the ground finally rushed out of the ground in advance, and happened to collide head-on with the ground creatures, to a certain extent, in fact, the loss of human beings was reduced.

It's just that in many cases, people's feelings can't be calculated simply by simple numbers.

Just as neither of them was about to speak, and were about to leave the cave, the crawling sound of skeleton monsters sounded again in the silent passage.

The nerves of the two immediately tensed, and at the same time, they slowed their breathing and slowly shrank their bodies in.

This time, however, the two didn't seem to be so lucky, and the crawling sound suddenly stopped the moment it reached the top of their heads, and there was no more movement. In Liao Yu's spiritual world, there was a mass of soul fluctuations gathered above, and it was difficult to distinguish the specific details.

Liao Yu and Zheng Wei both raised their hearts, and Liao Yu couldn't even help imagining that at this moment, directly above him, there were several skeleton monsters clinging to the mountain wall with their arms, and their upper bodies were quietly crawling towards the two of them. If you poke your head out at this moment, you can immediately see their elongated pale faces.

As they tried to shrink inward, both men aimed their guns diagonally upwards in order to attack as soon as possible.

There are pros and cons to their current position, and while they will not be besieged, they will have no room to dodge.

Just as Liao Yu's fingers pressed the trigger little by little, and it had been kept at the critical point, a huge hissing sound suddenly came out from the crack on the right side, which made Liao Yu feel that the familiar hiss was no less than the roar of the skeleton monster leader.

The moment the sound came out, a dense crawling sound immediately came from the top of the two of them, and it was obvious that the group of skeleton monsters began to rush frantically towards the source of the sound. As these monsters went away, Liao Yu and Zheng Wei both saw the joy of being reborn after the catastrophe in each other's eyes.
