However, entering the refinery this time was different from the last time. Last time, they went in to inquire about information.

But this time, they plan to take down this so-called oil refinery directly!

So, before going in, Lin Erdan took Xue Qingcheng to the water pump room.

They noticed this water pump house when they came here to collect information before.

The water pump house itself is where the water supply for the factory area behind is located. Xue Qingcheng saw Lin Erdan staying here for a long time and immediately understood Lin Erdan's thoughts.

"Erdan, do you want to poison me?"

Xue Qingcheng is not particularly averse to the method of poisoning. After all, sometimes many problems can be solved by using methods that are not available on the table.

"This is Shiri Ruanjin Powder, which is colorless and odorless. It is a very strong intoxicating drug. And once the effect of the drug takes effect, it will take effect for ten days. It will be automatically relieved after ten days. This time when we go in, we must follow

If the people inside fight against each other, if they don't make some preparations, they will still have a headache."

Hearing what Lin Erdan said, Xue Qingcheng also nodded, "That's right. If the other party resists, there will probably be many unnecessary casualties. What do you think we should do?"

"This matter is also simple." While Lin Erdan was talking, he had already brought Xue Qingcheng to the hut outside the gate. The two of them were extremely skilled, so no one noticed them at all.

After closing her eyes and listening for a few seconds, Xue Qingcheng stretched out four fingers towards Lin Erdan.

This is the same as the previous time. The last time they came to investigate, there were also four guards here.

"Yeah." Lin Erdan nodded lightly, and then took out a blowpipe from his sleeve. Without saying a word, he flew past the hut. The next second, a flying needle as thin as a cow's hair flew out of it.

Shooting out of the blowpipe!

A guard who was sitting at the table and reading a book only felt a little itchy on his arm, so he patted it subconsciously, not realizing that he had been hit by a flying needle.

After the first shot hit, Lin Erdan fired two more flying needles before the people inside realized something was wrong.

The three people who were hit by the flying needle didn't feel anything at the time, because although the flying needle was filled with a drug, it took about ten seconds to take effect.

This is the time Lin Erdan has been waiting for!

When the first person suddenly felt sleepiness rushing to his head, Lin Erdan had already knocked out the fourth person!

In an instant, the four of them fainted almost at the same time. This was exactly the effect Lin Erdan needed!

Lin Erdan snorted and shook his head gently. The Ma family was too relaxed, right?

In such an important place like the refinery, the guards outside were actually four ordinary people. It was really careless.

But this is also a good thing. After all, it is exactly like this that Lin Erdan was able to take down these guys so easily.

The next thing was even simpler. Lin Erdan poured all the prepared Tokasurujinsan into the water pump room.

Although this will greatly reduce the effect of Tokaruanjisan, it is still enough to deal with ordinary people in this factory area!

"Won't those guards realize something is wrong when they wake up?"

Seeing Lin Erdan's relaxed look, Xue Qingcheng asked with some confusion.

After all, if the guards found that he had fallen asleep, they would definitely suspect that someone had tampered with him.

Unexpectedly, Lin Erdan said with a smile, "Don't worry, the flying needles I stuck on them also have a background. The medicine smeared on the flying needles will make people lose consciousness for a short period of time. They will not even notice themselves.

I have already fallen asleep, but I feel like I suddenly lost consciousness."

Lin Erdan said as he walked out of the water pump room, "And they were only unconscious for about three minutes, so they wouldn't be aware of it."

"Okay, Erdan, I didn't expect that after you got the second half of the Medicine God's Manual, all the things you studied would be here." Xue Qingcheng shook her head helplessly and said, "If I really let you study these things

To the extreme, I’m afraid it’s not you…ahem…”

Xue Qingcheng obviously thought of some other places.

When Lin Erdan saw that Xue Qingcheng stopped talking, he immediately pretended to be confused and asked, "Afraid of what would happen if it weren't for me? Sister Xue, why did you stop talking in the middle of your sentence?"

"Ahem, you kid is asking questions knowingly!" Xue Qingcheng snorted and crossed the guard room and walked directly to the factory area.

Lin Erdan quickly followed, "Sister Xue, what are you talking about? I don't understand."

"You're such a naughty kid, what else do you don't understand? Huh, let's go, let's go to the factory and handle the matter quickly!"

Xue Qingcheng quickened her pace as she spoke. The reason she did this was entirely out of nervousness. After all, Xue Qingcheng was usually an iceberg beauty.

It was in front of Lin Erdan that she would say these words.

But even if she could let go of her body and mind in front of Lin Erdan, this kind of topic would still make her embarrassed.

"Hahaha! Okay, Sister Xue, let's not talk about this anymore. Let's go in directly!"

As Lin Erdan said this, he and Xue Qingcheng once again entered the real factory area under the eyes of the two sentries.

The two of them took the familiar road and headed straight to Hu Jincao's dormitory.

However, as soon as the two of them arrived outside the dormitory, they heard a burst of crying.

This voice is clearly that of Hu Jincao!

Lin Erdan and Xue Qingcheng looked at each other, not quite understanding why Hu Jincao, a grown man, was crying like this.

But the two of them had no time to guess. Lin Erdan didn't hesitate and kicked the outer wall twice.

After a while, he kicked twice more.

Following Lin Erdan's coded signal, the crying voices inside suddenly stopped.

Then there was the sound of chairs moving.

Then there was another click, the door was opened from the inside, and the person who walked out was Hu Jincao!

This time when he came out, he didn't act like before. Instead, he directly focused his attention on Lin Erdan and Xue Qingcheng.

He opened his mouth and seemed about to burst into tears. Without saying a word, Lin Erdan first sealed Hu Jincao's mute point with a silver needle and then pulled him into the room.

Xue Qingcheng naturally followed closely behind. After deliberately observing that no one was watching outside, she closed the door.

"Hu Jincao! What are you thinking about?"
