It's just that because the medical level at that time did not know much about the transmission characteristics of this disease, Qian Lu did not find any suspicions.

Liu Cheng only knows that this disease is very serious, and many people die of malaria in Africa every year, and most of them are young children.

The reason why malaria came to mind at the first time was mainly because Liu Cheng had seen many incidents in his previous life about patients suffering from the disease of love using needles to inject their own blood into other people's bodies in retaliation.

Also, in those days, who would be idle and idle to sneak attack others in this way?

At the same time, Liu Cheng did not suspect that this matter was done by Nagahei Masao, the reason is very simple, if it was Nagahira Masao, he didn't need to be so troublesome at all, just arrest or assassinate people directly.

Liu Cheng quietly put away the needle and walked straight out of the inn.

However, he did not go far, but went around and hid in an alley next to the inn.

From this position, he could see the other three directions of the inn except for the main entrance, and as long as someone came out, he could find it at the first time.

A few minutes later, a dark shadow crawled out of the wall behind the inn and fell as it landed.

Liu Cheng didn't think much about it, and quickly jumped out of the alley where he was hiding, and before the black shadow could react, he knocked it to the ground with a punch.

Half an hour later, Liu Cheng appeared in the backyard of Baicaotang again, went straight into the room and called Qian Lu up.

Qian Lu had just fallen asleep, and he was stunned for a while before he reacted.

Liu Cheng signaled Qian Lu not to make a sound, pulled him to the window, pointed to the black shadow and told Qian Lu what happened.

Qian Lu didn't speak, jumped out of the window and walked with Liu Cheng to carry the man who had fallen into a coma towards a room in the corner.

Qian Lu dug a basement in this room, and the space was not large, only three square meters square.

After sealing the entrance, Qian Lu lit the kerosene lamp and immediately asked Liu Cheng to take out the needle and come under the lamp to check it carefully.

Actually, it's not pretty, because it's just an ordinary sewing needle, just slightly larger and solid.

Qian Lu looked at it for a long time, raised his head and looked at Liu Cheng suspiciously, and said:

"This is just a normal sewing needle."

Liu Cheng glanced at him helplessly:

"Nonsense, I'm not blind, I just want to know if this needle can make me get malaria too."

Qian Lu shook his head with a bitter face:

"I can't say this well, it stands to reason that even if this needle is stained with the blood of the patient, the amount of it will be very small.

Malaria is not a virus, but a disease caused by a parasite, and I don't know if there is such a parasite in the blood that gets on the tip of the needle, so I can't be sure. ”

Liu Cheng pointed back at the person who was still in a coma, and asked Qian Lu with a frown:

"Do you know this person?"

Qian Lu picked up the kerosene lamp and approached the man and looked at it carefully:

"I don't know, I'm sure I haven't met this person."

Liu Cheng scolded in a low voice, and slapped the man's two mouths.

The man slowly woke up, and then looked at Liu Cheng and Qian Lu with a frightened expression.

Liu Cheng was almost angry, pinched the steel needle in front of the man's eyes, and asked in a deep voice:

"Why did you sneak up on me with this thing?"

The man looked to be no more than twenty-three or fourteen years old, with a thin and thin face like a thief, and at first glance he was the kind of person who was lazy and timid like a mouse.

After listening to Liu Cheng's words, the man's eyes rolled a few times, and he said with a wry smile:

"Don't be angry, uncle, I'm just for fun......"

"Smack!"

Before he finished speaking, Liu Cheng raised his hand and struck back, and beat back the words behind the man.

Immediately, Liu Chengcheng put the needle against the man's eyelid:

"Lao Tzu, will you give you another chance, as long as you dare to lie, I will pierce your eyeballs with this needle!"

The man trembled all over, and immediately begged for mercy in a loud voice:

"Don't, don't, don't! Uncle, I said, I said, please don't pierce! ”

Liu Cheng's hand was slightly forced:

"Less of him nonsense, say!"

"Yes, someone asked me to do this, he gave me a small vial of blood, and asked me to find two people every day to prick it with a blood-stained needle, a piece of ocean a day!"

"Who's that guy?"

"I don't know, but every night after dark he would come to my house and give me a vial of blood and a piece of ocean; I didn't dare to get close to people to pierce it, so he gave me this thing that could be blown away! ”

"How many people have you stabbed in total?"

"Almost fifty of them."

Liu Cheng could see from the other party's eyes that he was not lying, and slowly raised the hand holding the needle, and threw the needle on the ground casually.

As soon as the man breathed a sigh of relief, Liu Cheng suddenly punched him with a backhand, knocking him unconscious again.

Qian Lu looked at Liu Cheng a little nervously and said:

"It's bad, it seems that the people who are currently sick should have been infected in this way, and you are likely to have been infected!"

Liu Chengman waved his hand indifferently:

"Not necessarily, this thing probably depends on the body's resistance; Besides, with such a little bit of blood, it's not certain whether it can be obtained.

Didn't you hear him? There are more than 50 people in total, and about half of them are sick? Besides, there must be water in the more than fifty figures, and the probability is less than half, so it's okay. ”

Qian Lu shook his head and said with a serious face:

"I guess there must be some of these people who this kid said who didn't get hit, after all, the distance is relatively far, and it's normal to not get hit; But you are different, that needle was pulled out of your body, and the probability of infection is very high! ”

Liu Cheng sighed helplessly:

"That's no way, you give me some medicine tomorrow, I'll take it first, and I'll talk about the rest later."

At this time, Liu Cheng was basically able to determine who was the person who instructed this kid to do this.

Tomorrow, when he finds out that this person is gone, he will definitely take action.

Therefore, Liu Cheng must prepare in advance, only by successfully catching this person, can they have a chance to turn the tables, and those who have already become ill can be saved.

Otherwise, at least half of those people would probably die.

Before leaving, Liu Cheng woke up the man again, and after asking for the address of his house, he still punched him to continue "sleeping".

Indeed, Liu Cheng is taking revenge, and it has only just begun.

He is not a saint, he can't repay grievances with virtue, and he can't be tolerant.

Others want to kill you, it's not certain whether you can live or not, who can be tolerant?

Those who persuade others to be tolerant when they have nothing to do are all standing and talking without backache; When it comes to himself, he will be more ruthless than any retaliation.

When Qian Lu asked Liu Cheng how to deal with this person, Liu Cheng only said one sentence:

"Tie up, gag up, when to die, when to bury ......"
