"I'll touch the shadow first, it's more efficient. You should pay attention to safety alone. I may not be able to take care of you if you encounter any dangers." Julia put on a compact hat and wrapped her hair, ready to fight.

Lu Yu took out a set of armor from his portable space. Although he was good at it, no one could tell that he would encounter any danger.

"You go first and try to keep in touch."

After experiencing so many things, Lu Yu will never rashly break into an area that may be dangerous again.

He wore light high-performance material armor all over his body, a protective helmet, and even a lightweight life-saving device on his back.

However, the air in the cave is still OK and does not need to be enabled for the time being.

At the same time, the tactical slots on the armor were also filled with Lu Yu, several concentrated and dispersed light sources to ensure lighting, and a complete set of adventure tools are available at any time.

In terms of weapons, Lu Yu's main weapon is the double-barrel hunting rifle from his first copy. This gun is powerful and it is extremely convenient to use shotguns in close combat. After some strengthening by Lu Yu, the ammunition fired is more than twice that of ordinary shotguns.

In addition, the secondary weapon has prepared an AK series short carbin rifle, which takes up only two pistols in the slot in front of it, which will not affect the activity and ensure strong firepower.

There are also two fully automatic Korok pistols as auxiliary weapons, and even a machete is not allowed to be placed on the waist, and a dagger is also prepared on both legs.

Such weapons and equipment are already very strong, especially in caves located in inland areas. The only threat that Lu Yu could recall was actually the Zongzi in tomb robbery novels.

If these guys do it, they can already beat the rice dumplings to pieces, but if they don’t work, it will not be physically solved.

But for the sake of safety, Lu Yu also needs to improve some safety factors.

He released his robot and installed a weapon reconnaissance kit on it.

This kit includes a radar system that can penetrate hundreds of meters, a light weapon system mainly composed of a small-caliber Vulcan machine gun, with a load of more than a thousand rounds.

At the same time, the robot also carries a high-power searchlight to explore the way for Lu Yu in front.

All drones poured into the cave, sending back some signals from time to time.

In this dark space, Julia has become the home court, and her special abilities allow her to quickly shuttle through the darkness.

"Lu Yu, there are indeed upward passages in these caves, and there should be more than one. I~~~zizi~~some bloodstains, probably from a few days ago~"

The signal of Julia's communication with Lu Yu was not good. Lu Yu could only roughly hear her spotted blood, but could no longer hear where she found it.

However, this is not a problem for Lu Yu. If the robot's searchlight cuts into ultraviolet mode, it is easy to find the reflection of blood.

The three of them were lucky enough to fall from such a high mountain. In addition to luck, it is probably related to Chen Tianming's ability.

But at least based on Lu Yu and his understanding of Chen Tianming, it is acceptable to save lives and heal the wounded, but it may not be reliable to take two people out in such a dangerous and difficult environment.

The bloodstains lasted for a short period of time and then broke. After searching for searching for search lights, a cave was found. From the traces, Lu Tianming and others must have climbed.

Julia's signal was temporarily cut off, and the drone was not fully prepared in advance, and it was difficult to find subtle clues in the dark and tortuous cave.

When Lu Yu carefully searched for clues and climbed through caves, Julia had already found an underground stream.

The mountain is really dry, and the underground stream flow rate that I finally found is very small.

Julia found some gnawed bat skeletons next to the stream. The tooth marks left on the head are obviously human, and from a fresh perspective, it is highly likely that they were left by Chen Tianming and his party.

There are traces of wound treatment next to the bat skeleton. It seems that with Chen Tianming, the probability of survival of the group of three is quite high.

After leaving his mark here, Julia was about to disappear into the darkness again, but a slight tremor came from the mountain, accompanied by tremors, and there seemed to be some familiar sound waves.

"Lu Yu, Lu Yu~" The continuous calls were not responded. Julia took out the hunting blade, which was very representative of the "Hunter" rank, and then disappeared into the darkness again to continue searching.

At this time, Lu Yu had already discovered an abnormality. Although he could not contact Julia, some of the drones he sent received the collected vibrations and sound signals.

"How did this damn familiarity come about?"

Lu Yu stopped for the time being, letting the robot beside him, and at the same time took out his laptop to start identifying.

Since there was no network, he could only retrieve a limited local database. Even so, after some calculations, the conclusion reached by the computer still made Lu Yu sweat.

【Recognition completed: The sound wave signal is 70% consistent with the sound wave emitted when the sickle head appears】

Underground in the inland areas, sound waves similar to giant monsters by the sea appeared.

Even if the collected sound wave signals are extremely weak, once they are confirmed to be true monsters, human beings' strategy to prevent the "pioneer" will be completely disrupted.

"Julia, Julia, be careful, maybe monsters are appearing underground!"

If it is really a monster like a giant beast that appears on the beach, it is hard to say whether Lu Yu and Julia can escape without hesitation. I am afraid that they can only count on Ultraman who suddenly appears?

———

Deep in the mountain, the monster continued to walk slowly along the cave. For the monster, he always had enough patience to sneak in the darkness.

At this time, the buzzing sound from around him made the monster stop suddenly. Its oval head shaking and found a small drone that was automatically cruised. Then he slapped his tail and smashed the three small drones to pieces.

Then it seemed that it was still unsatisfied, and then it used its tail to slam it heavily on the rock wall, as if it was venting its endless energy.

However, this heavy blow caused trouble to Chen Tianming and the other two who were not far away. They were already afraid of hiding in the narrow cave. At this time, the vibration caused by the heavy blow made the stones in the cave roll down suddenly. Even though Chen Tianming tried his best to lead Timi and Jim to avoid it, he was still beaten to death.

At the same time, the monster's inadvertent venting passed on its position to Julia who was wandering in the darkness.

She finally called Lu Yu: "I can already determine where this strange happened. I want to go and see, Lu Yu, be careful yourself!"
