12 In the huge room, Lin Yue looked around carefully.

The rancid smell has disappeared a lot, and my nose has gotten used to it a little bit.

Lin Yue searched for any clues on the ground.

Soon, he discovered two circular patterns on the ground. There was no doubt that this was the entrance to a secret space.

"As long as you open this, the question you just asked will be answered."

Lin Yue looked at the corpses on the ground again.

There are 104 corpses of lizardmen here, and 45 corpses of beggars.

The 104 lizard-man corpses, the 27 lizard-man corpses he found outside, and the three turtle crocodile corpses added together were exactly the number of 131 treasure chests he obtained at that time.

But the treasure chest here no longer exists, and even the light spots in the storage space where the beggar should be able to stay have disappeared.

At that time, the cave collapsed, and the lizards and beggars here must have blocked the door with countless stones. In the darkness and panic, they quickly ran out of oxygen, and finally all died.

But the current situation is very strange.

The treasure chests and storage spaces in the room disappeared, and there is no doubt that this should be impossible to happen.

unless……

"Did some beggars survive and pick up the treasure box and storage space? But the lack of oxygen was severe at the time, and the only escape route should be..."

He walked to the center of the two circles.

There happened to be the remains of a lizard man on one of the pieces there.

just.

Lin Yue seemed to have thought of something.

After dragging the remains away, Lin Yue placed a stone on top.

A sound of "Gragla" sounded. Lin Yue looked towards the place where the sound came from, and found that the sound did not come from his feet.

And it was the passage he came from from area C2!

Lin Yue glanced at the corpse of the lizard man just now again, and seemed to have some more answers to his thoughts.

At this time, the system suddenly made a sound!

[Congratulations, you have broken through Area C of the underground ruins!]

Lin Yue opened the system panel and saw the announcement above.

【World Announcement, World Announcement!】

[It has been detected that survivors have unlocked the entire map of Area C of the underground ruins. It has been detected that survivors have unlocked the entire map of Area C of the underground ruins!]

[This is the first time that a survivor has unlocked the underground ruins partition map. According to the rules, the system will issue first-pass rewards to this survivor!]

[The reward this time is, Platinum Treasure Box x1!]

The platinum treasure chest is here again.

A burst of white light flashed, and a platinum treasure box appeared on the ground. Lin Yue pocketed it.

However, this did not disrupt his thoughts, but gave him a clearer understanding of the entire incident.

It can even be said that he has already thought of the answer to this mystery.

Lin Yue walked around here again and took pictures of the murals on the wall with the help of the light of the flashlight. He was about to go back when a loud sound sounded and the stone door from where he came from was closed again.

Lin Yue was not panicked.

He went directly to the two circles, pressed a stone on them again, and the door reopened.

Lin Yue understood that this thing would turn off again after a certain period of time, and it needed to be turned on again.

This once again confirmed his thoughts this time.

After returning to Area C2 and looking again at the fork in Area C2 that clearly led to another passage to another area, Lin Yue made a wall with iron blocks to block that side.

Afterwards, he took Xiaomeng and the little ice lizards back to the shelter.

"Gahw..." Xiaobai, Xiaoliuzi and Hongxian were waiting for their return at the door, but the strong corpse odor made them almost faint.

"Something happened inside, Xiaobai, please wait for a while, I will take them to give them a good wash."

Lin Yue used a thick iron wall to seal off the ancient gate of the underground ruins, and took Xiaomeng and the other little ice lizards directly to the bathroom.

After using more shower gel than expected, Lin Yue finally managed to reduce the corpse odor on his own, Xiaomeng's, and the little ice lizards' bodies.

I have to say that the smell was quite unpleasant, especially if it was on the hair. It made Lin Yue want to shave his hair.

In the end, there was no other way. Lin Yue chose to use up the remaining half of the bottle, and washed himself and Xiao Meng thoroughly again. Although there was still a little smell, it was still much better than before.

After washing, Lin Yue felt refreshed and his mind was clearer and calmer.

After drying his hair, Lin Yue came to the living room which was extremely cool, even a little cold.

Sitting on the comfortable sofa, watching Xiaobai and the three of them wandering around Xiaomeng and the others, Lin Yue took out the pen that he hadn't used for a long time, and took out the diary that he had taken out from the abandoned shelter.

Book.

A good memory is not as good as a bad pen. Of course, when thinking, if you have a pen and a notebook, it will make the thinking circuit clearer.

Turning over the pages filled with writing, Lin Yue took a pen and wrote a line of words on the paper.

When you eliminate all impossibilities, whatever is left, no matter how unbelievable, is the truth.

This is a famous quote from Sherlock Holmes.

After Lin Yue accidentally saw this mystery novel in the school library when he was in middle school, he regarded this famous saying as one of his creeds.

And now, this creed has once again reached a final conclusion on this matter.

This conclusion may well have revealed the truth.

That day, he used an incendiary arrow to ignite a gasoline barrel. While blowing up the intersection, it also damaged the main structure of the entire underground ruins in Area C. After that, Area C began to collapse and finally collapsed completely.

The lack of oxygen caused by the collapse soon killed the lizards, beggars, and turtle crocodiles in Area C that he had not yet killed. At the same time, he also brought 128 copper treasure chests and 2 silver treasure chests.

4 gold treasure chests.

Among the 4 gold treasure chests, 3 belong to turtle crocodiles, let’s not talk about them for now.

Lin Yue drew a circle on the three gold treasure boxes and marked them with the word turtle and crocodile.

128 copper treasure boxes, 2 silver treasure boxes and 1 gold treasure box. These were originally what he was supposed to get when he came to Area C of the underground ruins this time.

However, he only obtained 25 copper treasure chests and 2 silver treasure chests. The remaining 102 copper treasure chests, 1 silver treasure chest and 1 gold treasure chest were missing.

Also missing were the storage spaces left by the bodies of those begging for survival.

Then, the problem comes.

Storage space aside, those treasure chests don’t just disappear.

The evidence is that he still successfully recovered the 27 treasure chests left by the lizard men buried under the rocks. This explanation is also impossible.

The treasure chest cannot disappear on its own. From the smell that comes out when the secret passage is opened, it can be seen that Area C has not been opened since the last time it collapsed.

How did the remaining treasure chests and storage spaces disappear?

Lin Yue drew a circle on it, and an arrow extended from outside the circle.

At the end of the arrow is a line of words.

It was taken away by someone.

There is only one answer.

So, let’s first assume the situation at that time.

The huge vibration caused by the explosion soon triggered a strong chain reaction. The passage was flooded with huge rocks for a while. The rubble quickly blocked the exit of the huge room and directly killed 27 lizards.

At the same time, a large number of lizards and beggars who were in the huge room were directly trapped inside.

The oxygen was quickly exhausted, and the torches on the wall were extinguished one by one. In the darkness, the lizards and beggars who didn't know what was happening were also panicked. As a result, the consumption of oxygen was aggravated.

Each one struggled and fell, and in the end each one died from lack of oxygen.

Except, one person.

This person used some special method, or luckily he didn't suffocate to death directly. When he opened his eyes again, he found that there were treasure boxes and light spots in the storage space everywhere, and he quickly harvested them all. After that, he

He dragged the body of a lizard man to the circular pattern on the ground, opened the secret passage, then walked out of Area C2 and successfully survived.

After a certain period of time, the mechanism resumed operation, the secret passage was closed again, and the place was completely closed.

Only some bugs and the like came out from the cracks in the rocks and found a large number of corpses, and they multiplied in large numbers here, quickly eating up all the meat on the corpses here, leaving only

Those bones.

Lin Yue roughly wrote down his inferences in his diary.

If there is an explanation that can completely solve this mystery, then it seems to be the only one.

Someone is still alive and has stolen the fruits of his victory - most of the treasure chests and all the storage space.

The method used...If you are deprived of oxygen, you will definitely not be able to pick up any treasure chests or light spots in the storage space by covering your nose. If you are not breathing, you will not be able to do this even if you hold your breath for the longest time.

Not to mention searching for these things in the dark.

Therefore, this person should have had an oxygen tank or a respirator, and he survived by luck.

After picking up the treasure chest and storage space, this person directly opened the door of area C2 and escaped.

This should be the most reasonable explanation.

Lin Yue put down his pen.

This person really exists, and is a threat to him.

You can imagine, after seeing the treasure chests next to each lizard man and pocketing them, what else would this person be thinking about besides being ecstatic?

Is the explosion rate of treasure chests a bit outrageous?

If it were him, Lin Yue felt that he would definitely think so. After all, this is the fact.

The normal explosion rate of treasure chests, if analyzed from the chat records in groups and world channels, is really not much. Even the European Emperor has to kill six or seven mutated creatures before he can explode one.

104 Lizardman corpses, there are 104 treasure chests, including silver treasure chests and gold treasure chests...

Everyone would think too much about it.

Moreover, the matter of "100% explosion rate" will soon be taken seriously.

No one else has the ability to 100% explode the treasure chest, otherwise he would not be the only one in the top 100 in the world rankings, but would be competing with another person.

Lin Yue believed that the surviving beggar had also guessed this.

I'm afraid, some related actions will be taken because of this.

Lin Yue looked at the diary again. What was written on it was his inference just now. Although it was basically confirmed and affirmed the existence of this beggar, there was no definite evidence - a beggar came to the door specially.

If you ask questions, then this matter is not completely certain.

Looking through the diary written by the previous owner of this diary, Lin Yue once again remembered a mystery inside.

Du Ping is still alive, after being killed by him.

Could it be that the person who was killed was not Du Ping, or was it really Du Ping, and the Du Ping mentioned in the diary was actually another person?

It seems impossible, after all, there is really no such thing in the records of that period after he killed Du Ping.

But...who can say for sure.

Lin Yue closed the diary again and stood up.

Today has just begun. Although I have already broken through two underground ruins and obtained two platinum treasure chests and a bunch of other treasure chests, I have no time to open them now.

Walking out of the cool and comfortable room, Lin Yue faced the strong enough sun and put the already hot but fully charged robot dogs on the ground into the storage space.

However, when he returned to the house, he remembered something again.

Wait, wouldn’t it be interesting if the rocket launcher RPG was installed on the body of the robot dog?

Just as he said, Lin Yue went to the basement, took out the high-precision research workbench and the rocket launcher RPG he had obtained before, and then decomposed the rocket launcher RPG into design drawings.

Lin Yue unexpectedly discovered that the various things required on the design drawings were actually based on alloys and were not complicated.

Moreover, I don’t know if it’s a bug. When these weapons are made, even if they don’t contain the raw materials for ammunition, there will be bullets in them. This is true for the previous M19, and later the Sprayer and MP5 submachine guns.

The same goes for current RPGs.

The difference is that RPGs only have one warhead.

However, it is enough. There is no need to elaborate on the power of this thing, and its deterrence is sufficient.

But the disadvantage is that it is a bit dangerous, and Lin Yue doesn't want to play with it himself.

Lin Yue took out a robot dog and leaned on it the bazooka RPG that he made that shone with metallic light.

Soon, the system sound came.

[Upgrade the multifunctional defense robot to a high-destructive assault multifunctional defense robot (loaded rocket launcher), which requires a universal upgrade design x1]

Oops, I didn’t ask for the intermediate universal upgrade blueprint, that’s not bad.

Lin Yue immediately used a universal upgrade design drawing, and soon the robot dog's form also changed!

"Good guy, the rocket launcher is carried directly on the back. Who can see this?"

He found that the rocket launcher also had infrared aiming, and the system operation seemed to be very simple. You could select the minimum threshold when launching the rocket launcher.

"Then, let's set it up that when the number of enemies exceeds 100, we won't use the M19 pistol or MP5 submachine gun to attack, and activate the rocket launcher."

He was so satisfied that his robot dog had new changes, and he couldn't help but start to imagine, if the beggars saw such a robot dog appear, then...

Wait, why not?

Lin Yue installed all the robot dogs with rocket launchers, and at the same time he came up with a crazy idea.
Chapter completed!
