Luo Yan walked through the location of the iron gate to the underground of the fourth layer, and then used the perceptual diffusion to obtain the surrounding situation. Luo Yan was first stunned by the scene on the fourth floor, which was about twice the size of the previous floor. And the surrounding arrangement is full of technology, there is a large glass pool on both sides of the fourth floor, and a large plant with very large leaves is planted inside, which is Tebaku. There is even artificial sunlight above the glass pool to maintain the normal growth of the plants.

Although this kind of project may seem grandiose and high-end, it is not necessary to spend so much equipment and facilities normally. And the only thing Luo Yan could think of was that this was the wilderness of Vermilion Bird City, that is, the jurisdiction of humans. Then it is very likely that the Terrans do not allow the cultivation of this plant, so they can only be cultivated secretly. Previously, on the Cameron factory, it belonged to the jurisdiction of the goblins, and even if Tebaku was a prohibited plant, according to the characteristics of the goblins who were greedy for money, it was something that could be solved by stuffing money.

But why did these goblins stay so well in Demon City, but they had to go to the jurisdiction of the Terrans to get these things, this is a question that Luo Yan can't know yet.

This layer of goblins is dressed somewhat like that of a human scientist, dressed in white and wearing radiation glasses. And the attribute is also ridiculously low, and Luo Yan can solve it with the triple true injury crit of the Hidden Blade. Luo Yan found a corner and went into invisibility, and then sent a message to Lan Bing.

"Blue Ice, you remember to place a corpse explosion trap."

"Brother Layan, who knows, I don't want you to rest assured." Lan Bing said with a slight annoyance.

As the name suggests, the corpse in the trap will explode, so once this trap is triggered, even if the effect of the other traps has passed, the corpse explosion will always have a chain effect, and a pile of corpses will blow up the targets that come one after another, and then the cycle continues.

Luo Yan quietly touched the side of a lone goblin scientist, popped out his Hidden Arrow to easily level it, and then dragged the body into the corner. He then locked onto the corpse target and activated the phantom effect of the Phantom Cloak.

The so-called phantom effect is a kind of trick, and on the surface, Luo Yan has become this goblin scientist. But if you touch Luo Yan's body with your sense of touch, you will find that Luo Yan is still the same as before. In other words, the equipment that Luo Yan should have is still there, but it has been hidden.

This time, Luo Yan didn't even need to be invisible, so he walked towards the next target with a calm face, and almost at the moment when he passed by one of the goblins, the Hidden Blade had already pierced into the neck of the goblin, and without the slightest sound, another goblin lay down. On the surface, it seems that the goblin scientist raised his hand, but the real situation is that the head of the goblin scientist only reached Luo Yan's crotch, so in fact, the upper body of the invisible half squatted and wiped the throat of the target.

Of course, it doesn't matter how it is, the important thing is that Luo Yan can blatantly level these experts who focus on experiments, which is more exciting than touching and stabbing to death in a stealth state.

After leveling all the targets on the fourth floor, Luo Yan began to look for the so-called antidote, which according to Berg's description was a green bottle of medicine, but Luo Yan rummaged through it for a long time and did not see a trace.

"This Berg can't be colorblind, all I see here is a blue medicine bottle!" Luo Yan complained, thought about it anyway, and threw it all into the backpack. Then Luo Yan unscrewed all the Tebaku like bandits, these things that resemble tobacco in reality, can produce a lot of smoke after burning, and then stacked all Tebaku together.

Just as Luo Yan was about to ignite it with fire, his golden pupils swept into the drawer under the lab table, and found a dark compartment inside the drawer. It's like finding a hidden prop.,A sense of accomplishment arises spontaneously.,Then immediately pulled out the drawer.,Take out the inner dark grid.,In the dark box there is a drawing and a plain text paper.,Although I can't read it at all.,But there is a human-like signature at the bottom right of this paragraph.。 Of course, the most important thing is that there are actually three green medicine bottles in this dark compartment, which makes Luo Yan finally breathe a sigh of relief, originally if Luo Yan left, it was likely to fall short.

Royan lit Tebaku with a lighter, and then poured a small bottle of water, which would create the effect of being full of smoke without creating a real fire.

Then Luo Yan opened the door of the fourth floor and entered Luo Yan's performance stage. I saw Luo Yan show a trace of anxiety, and quickly ran to the top of the stairs, shouting as he ran:

"There's an accident in the lab! Get out of here, everybody! ”

The originally noisy third floor instantly fell silent. Luo Yan showed a nervous look, not knowing what would happen next.

"What? On fire? ”

"That's right, all the goblins of the third layer hurry back to the surface, these Tebaku smoke will make people hallucinate!"

"It's really! Look at the smoke down there, it's already filling up! ”

"Run, it's on fire!" At this point, it seemed that a goblin took the lead, and all the other goblins rushed to the top of the staircase. Luo Yan watched all the goblins rush forward, and immediately sent a message to signal Lan Bing to prepare. Luo Yan showed an evil smile at this time, I won't kill you now.

"Hey, Shi Zhenxiang, why are you different from usual." At this moment, an escaped goblin suddenly stopped, revealing a suspicious expression.

"Shi Zhenxiang? Oh, oh, yes, I'm Shi Zhenxiang, what's different about me. Luo Yan said while sweating wildly in his heart, how did this girl get a name.

"I think you're dumb, I've never seen you speak."

"If I haven't spoken, does it mean I'm dumb, let's go, it's too late." Luo Yan said with a blank look.

"Oh, good." At this time, the goblin was about to leave, but he stopped again and said:

"Oh no, the smoke in this laboratory is so thick, why don't you go in and solve it, what are you doing standing here?"

"The others are already working it out, and I'm here to evacuate the crowd." Luo Yan's forehead was beating, and he gritted his teeth and said.

"Oh, then I'm leaving. Hey, I'll ...... later."

Before this goblin could speak, Luo Yan couldn't help it, and immediately kicked the goblin's head, and then stabbed his head and face.

"As long as you talk a lot, you have nothing to add to yourself, isn't it good to be a passerby." Looking at the goblin lying on the ground in a miserable state of death, Luo Yan finally let out a long breath. Then he immediately opened his golden pupils and looked in the direction of blue ice.

The moment a group of goblins stepped around the corner, they were sucked into the trap as if they had been pulled by something. The gravitational trap had a radius of thirty yards, and some of the goblins who had not yet had time to enter the staircase were also pulled in.
