Two hours later, one man and one eagle came to a valley.

There was a very obvious crack in this valley, which looked like a sharp blade directly splitting the mountain. Even a long crack was left on the ground.

Patsha pointed to the front and said, "It's there, the underground base built by Coboland Company here has been at least twenty or thirty years, otherwise it wouldn't have been in such a scale!"

Song Jian squinted his eyes and looked forward. The entire valley had been built with steel and concrete to form a fortress-like building. Black artillery barrels could be seen on the mountains on both sides. If another wall was built in front of the valley to block the entire valley, then this place would be a small military town.

"Why didn't they build a wall?" Song Jian asked, pointing ahead.

"Who knows?" Patsha combed the feathers on his shoulders with his long beak and said indifferently: "It's already strict enough. If you build a wall, will you give others some way to live?"

Song Jian frowned and shook his head slightly. Could it be that when Coboland Company built this place, he expected that it would obtain meteorite fragments in decades, and then a group of assessors would come here to grab it. In order to make them successfully, they deliberately reduce the difficulty and do not build a wall?

How is this possible!

If he was the owner of this base, even if the internal facilities of the base are not perfected, the defensive walls would have to be built. As the owner of a city, Song Jian knew that the walls were the most profitable defensive building among all the defensive facilities.

"It seems that there is no one in the base?" Song Jian suddenly found that the surroundings were very quiet, and no movement came from the base. Could it be that the base had specially made sound insulation facilities?

"They are all installed here. Maybe their people are inside the base, and the security force on the ground is very weak?" Patsha shrugged his shoulder and said, "As soon as we approached, we were warned and did not dare to go deeper, so we could only retreat. Even those who were at most sneaking skills were only close to buildings above the ground. They found a passage that went straight to the cracks in the underground, but as soon as they approached that passage, they were discovered. The other party seemed to have very high-tech scanning equipment!"

Song Jian nodded. To put it bluntly, stealth technique is just to hide one's figure and use light to deceive other people's eyes. There are many things, including sound, smell, and temperature that cannot be hidden. In modern society, it is easy to prevent it. What's more, in this world where technology is obviously much higher than modern society, a simple infrared detection can make the stealth technique that the thief profession has worked hard to waste.

"It means, can't you go deeper?" Song Jian asked.

"There's no way..." Patsha shook his head and said, "But I'm just listening to what others said. You know, I'm not in the Inhuman camp, and they won't tell me some particularly important information..."

Song Jian nodded and said to Patsha: "You wait for me here first, and I'll go in and take a look."

"You can still sneak a trick?" Patsha said in surprise.

You should know that stealth is the core skill of the thief. Other skills and medicines such as secondary stealth, stealth potion, etc., are simply impossible to compare with the thief's full-level stealth technique.

"Try it, I will withdraw if I don't!" After Song Jian said that, his figure slowly disappeared in front of Patsha's eyes.

The abyss concealment technique is not as good as the maximum stealth technique in terms of invisibility effects, but its principle is to create a ball of abyss breath that wraps the user up. Not only can the eyes, smell, and body temperature that can deceive people from the light will be hidden very deeply due to the existence of the abyss breath.

However, the most suitable place for the Abyss Hidden Technique is the Abyss Hell, where it is full of abyss aura. Using the Abyss Hidden Technique is like a fish in water, without any flaws.

However, in the environment outside the abyss hell, the abyss breath can actually be detected by many professions. They do not need to be able to see through invisibility, they only need to be able to feel the existence of the abyss breath to determine Song Jian's location. This is the biggest flaw of the abyss hidden technique!

However, Song Jian believed that they could not detect the existence of abyss aura in front of him.

After entering a hidden state, Song Jian easily approached the base. He found that there was not a city wall outside the base. There were many materials for building the city walls, which were all placed under the mountains on both sides. It was obvious that he was preparing to build the walls from the mountains on both sides, but for some reason, he was delayed.

Didi~

At this moment, Song Jian heard a sound of electronic activation coming from the base. Soon, a mechanical synthesizer sounded across the entire periphery of the base.

"This is the underground base of Coboland Company. All acts of breaking in without permission will be subject to active attacks by Coboland Company. According to Article 367 of the Defense Law, the attack does not require advance warning..."

Song Jian's movements suddenly stopped, but soon, he continued to walk forward. Patsha told him that this warning should have been set in advance and will automatically play after a period of time. It is not really discovered that someone broke in.

After getting closer, Song Jian saw that there were many naturally formed stone pillars in the valley. These stone pillars were smooth and straight, and there were carved traces on them, but these traces had been artificially erased, leaving only some faint marks, and the content of the carving could not be seen at all.

Continue to move forward, under the rocks of the mountain, Song Jian saw a huge artificial cave. The edges of the cave were very smooth, and the walls inside were all made of cement hollow bricks, which looked rough and sturdy.

The cave is at least five meters high and ten meters wide, so it is easy to allow a loading vehicle to enter and exit. Moreover, there are obvious defense facilities on both sides of the artificial cave. Two of the machine guns are still on standby at any time. The electronic equipment that controls the machine guns is still shining, but a thick layer of dust fell on it, which seems that it has not been maintained for a long time. Some traces of rust have even appeared on the barrel.

Song Jian frowned slightly, as if he had some bad premonition. After observing for a while, he continued to walk in and then walked forward, and he had already entered the mountain.

Soon, Song Jian came to a hall. The hall looked very wide, as if the entire mountain had been hollowed out. There was a hard metal base plate under his feet, and there were many supplies parked around him, some of which had been opened, while others were firmly tied.

Continuing to move forward, Song Jian saw a slope five or six meters wide, leading straight to a deeper underground. At this time, there were emergency lights in the hall. Although the light was dim, it could barely see the surroundings clearly, but there was no light under the slope, and it was dark and I didn't know where it led.

Song Jian thought for a while and continued to walk forward. Just as he had just stepped onto the slope, a sudden sirens of shock sounded. At the same time, several defensive machine guns suddenly appeared on the walls on both sides of the slope, and at the same time, a red laser sight shot towards Song Jian's direction.
