C507 Suspicious traces

After resetting his invisibility, Lu Shan immediately sped up and left the corridor he was searching for previously. Soon after, he felt a sense of loss again …

After all that had happened, he had already searched almost all of the three corridors within the Secret Base. It was the long corridor where many of the laboratories were located, and he had not examined it too closely before. However, after he pondered for a moment, he felt that … The possibility of the Spear Array's control room being placed there was practically non-existent.

And in fact... Actually, this control room being placed in any corridor within the base shouldn't be too reasonable.

After all, according to Lu Shan's analysis, the reason the secret organization set up such a Spear Array in their Central Hall was to snipe the enemies that had already snuck into the base. If they were going to deal with the enemies that came in from the outside … Since that was the case, there was no need to set up the Spear Array in the Central Hall. Setting up the hundreds of meters long pathway leading to the outside world would definitely be more suitable.

If what he had guessed was true, then the Spear Array's control room would definitely not be placed in any of the three tunnels. Otherwise... If the person who infiltrated was stopped by the Spear Array s of the Central Hall and was unable to charge out in a short period of time, the person would only need to turn around and kill … If he could find the Spear Array's control room, wouldn't that solve everything?

Therefore, if the Spear Array's control room was placed inside the base, it would not be very wise! Then... Could this control room be placed outside the base... In other words, the wooden house in the col?

If that was really the case, then it would be troublesome, how could Lu Shan control the mechanism to get in and out of the secret passage? Moreover, if he were to fight his way out from the secret passage … Then what would happen if the Ning Siblings that was still inside were to be discovered?

But at a time like this, Lu Shan could not worry about anything anymore. No matter what, he had to first find the Spear Array's control room, otherwise … The Ning Siblings would definitely not be able to come out safely. In the end, wasn't it still a dead end?

Thinking about it, Lu Shan clenched his teeth, and then headed towards the long path that led to the outside of the base.

However, Lu Shan did not even crawl on the ground as he quickly ran towards the exit because... He suddenly realized that the passageway connecting the inside and outside of the base was a little too long! Although there were no doors on either side of the long passageway, but … There might be some hidden secret chambers on both sides of the path.

And most importantly … Lu Shan suddenly remembered that earlier, when he triggered the alarm in the cove, after the group of militants outside did not manage to search for anything, they had reported this incident to a person called the High Team through video. In the end, not even two minutes later, the High Team opened the Hidden Door from their Secret Base and led the thugs out.

Clearly... It was precisely because of this that Lu Shan had the chance to sneak into the Secret Base without anyone knowing. Otherwise, just that Hidden Door alone would not be able to open it without alerting others!

At that time, he didn't pay much attention, but now, he suddenly realized … What position in the base did the Gao team have to be able to walk out of the secret passage in less than a minute?

Speak... He would have to walk for at least three minutes to pass through this long passageway. Of course … If he was running at a high speed, he should be able to pass through the tunnel in less than a minute.

But in fact... At that time, the situation was not that urgent and the high-ranking officer was clearly someone with status in the evil organization. He shouldn't have run away so recklessly, right? Besides... At that time, Lu Shan had brushed past that group of people, but he hadn't felt any indication that these people were running fast!

Generally speaking, even a well-trained athlete, after running at high speeds for more than a minute, would definitely be out of breath. At the very least, their breath wouldn't be as stable as usual.

So... Judging from this, that group of people did not run at all! This also meant that … It was impossible for them to have passed through the entire tunnel, and rushed over from an area near the Central Hall!

Then... Where was that high team when they received the report? He couldn't possibly stay in this passageway forever, right? This... Could it be that somewhere in this path, there was a Hidden Door that could lead to another area of the Secret Base?

Lu Shan's eyes immediately lit up, and he immediately slowed down his footsteps. He continued to walk towards the secret passage while carefully observing the two sides of the passage, and carefully listening for any suspicious sounds.

However, Lu Shan quickly realised that if he kept on searching like this, it would be too slow. He might not even be able to find the Hidden Door that he was hiding at all, and he might just run out of time to go into Stealth!

He immediately changed his method and moved quickly to the exit of the secret passage. Then he turned around and walked back to the passage at the normal speed of a normal person.

This way... He walked back for another minute before he started to observe the two sides of the corridor carefully.

If his judgement was correct, Gao Feng's group should have also been near the exit, which was why they were able to reach the exit within a minute or so. Therefore … If there really were Hidden Door in the tunnel, they would definitely be within a certain radius.

After determining the general area of doubt, Lu Shan searched even more carefully. It wasn't long before he found an extremely suspicious location.

If one did not look carefully, they would not be able to see any difference between that place and the surrounding stone walls of the tunnel. All of the walls were formed from jagged and uneven mountain rocks, but when Lu Shan observed them carefully, he realized that … In this place, there was a piece of rock the size of two palms, looking extremely smooth. It was as if someone was constantly rubbing the rock with his palm … This fellow, he was so engrossed that he was about to drop the pulp!

Speaking of which... If it was the rocks on the mountain outside, some of the stones would look smooth, but this place was a man-made tunnel. The walls on both sides of the tunnel were full of potholes, but only this place was smooth like this.

So... Lu Shan was basically able to confirm that this location should be where the Hidden Door in the Secret Base was headed to in another region! However, what he was slightly worried about now was … I wonder if this Hidden Door was manually activated? Or was it controlled by an electronic level, or something like a password? If it was the latter, then Lu Shan would have no choice but to break through the door violently!
