You must know that the most important thing for a killer in the assassination process is to seize the moment, complete the task quickly and flee the scene.

So, time is a very critical thing.

If the poison Ann gave himself was the poison that Jack would use, then it was clear that these people could be counterattacked by Jack a few minutes after being poisoned.

People with extremely strong physical fitness will wake up a little earlier, but by this time, Jack has almost made people half dead, so these people don't know how they died.

No wonder there is so little information, no wonder there are so many killers who have never returned.

Gu Sheng originally thought that Jack was just an extremely powerful master, quick in action, and killing people invisibly, but he didn't expect that the other party was the same as himself, he was also a poison maker, and he seemed to be much smarter.

After getting the formula, Gu Sheng was not afraid that she would not be able to develop an antidote, so she finally put her mind at ease, she sorted out all the documents and formulas, and went to bed easily.

The next day, Gu Sheng got enough sleep, got up full of energy, and immediately ran into the laboratory, very excited to start studying the poison formula that Ann gave her last night.

Gu Sheng now concocted a copy by himself and studied the mice in the laboratory, and sure enough, as he imagined last night, it was indeed a gaseous transmission, and it would leave the human body without a trace.

In addition, after the killer is killed, although some people will notice whether they have been poisoned, nothing has been detected in the blood, and they will not continue to study this piece too much.

It was only now that Gu Sheng knew how Jack had been left alone and had never died.

It's just that the conditions for making poison are too harsh, and if even a penny is missing, the toxicity of the poison will be unstable and the effect will not be achieved.

The first time he got started, Gu Sheng also failed several times before finally researching the results.

It's just that a long time has passed.

After concocting the poison, Gu Sheng began to admire himself as the person who was about to be assassinated, his idea was very genius, although some people studied how to make the poison leave no traces, but as far as the current situation was concerned, no one had done it at all.

In other words, those who do it, others don't know what kind of poison it is.

This time, if it weren't for An, Gu Sheng wouldn't dare to imagine what would happen to him after he came into contact with these poisons.

What's more, this antidote also takes a certain amount of time.

Seeing that the task was just tomorrow night, Gu Sheng looked at this poison that surprised him, and stabilized his mood, not wanting to let the time urgency affect the mood of concocting the antidote.

"Hoo ......"

After breathing a few times, Gu Sheng began to look at the poison formula again, and began to quickly write various chemical equations on the whiteboard in the laboratory, and deduced a series of products.

And what makes Gu Sheng feel the most powerful is that these products can continue to produce more complex chemical reactions between them, and the products can easily enter the blood, combine with hemoglobin, produce new substances, and eventually return to their original state and leave the body.

That's why it doesn't leave a trace.

Gu Sheng glanced at the chemical formula again, although she didn't have any good ideas at the moment, but the more difficult the challenge, the more interesting she felt.

"How do you get it......"

While writing her thoughts on the white paper, Gu Sheng muttered over and over again, this feeling she has rarely had, talent and usual hard training have long allowed her to do things quickly and handily, and there is almost nothing she can't solve.

But this time, it seems to have returned to the very beginning when she made fragrances, facing hundreds of spices, at a loss, and having ideas, but they are all hovering in her head, and it is not easy to grasp.

There are already a lot of things on the paper, but none of them can be used, either the dosage is a problem, or the related agents will react with the poison and create more problems.

It has been nearly eight hours in the laboratory, during this time, Gu Sheng has only drunk some water, and has not eaten anything else, and when he feels dizzy, he eats a few candies slowly, and he doesn't think about leaving at all.

"I've heard from others that you've been in the lab for a long time today and haven't even eaten?"

Gu Sheng broke free from a pile of chemical manuscript papers, and looked at the person standing at the door, it was a wolf, with food in his hands, and he looked pretty good.

After knowing what Sky Wolf thought about him yesterday, Gu Sheng felt the need to keep his distance.

But she thought about it, from the beginning to the present, the distance between her and the Heavenly Wolf has always been very far, and that man was also protecting himself because of the ghost's order at the beginning, and now, this has become his habit, as if his duty is to protect Gu Sheng.

This feeling is even more and more weird.

Obviously, it was such a distance, no matter how he said it, he maintained a relationship with other people around him, and Gu Sheng didn't know how to respond to the sky wolf for a while.

Fortunately, Tian Wolf didn't say anything, just put the things on the table, told Gu Sheng, remember to eat on time, and then left.

In a hurry, it seems that there is something important on his body, and he just took the time to go out, and he is going back immediately.

Gu Sheng looked at the food in front of him that seemed to be delicious, but he didn't know how to eat it.

Her heart became extremely heavy.

Gu Sheng has not had no suitors, those inexplicable people will surround her, all in order to catch her up and become her boyfriend.

There are also people who have a secret crush, and Gu Sheng can also see one or two, but everyone is just not in a state of debunking.

But this was the first time, Gu Sheng felt the feelings of the heavenly wolf that didn't need to be responded to by himself at all, and he just needed him to pay silently alone.

In the past, Gu Sheng just felt a little puzzled, why spent a lot of time, energy and affection on a person who knew that he would not get results, so she didn't feel anything.

But now, from the Heavenly Wolf's body, Gu Sheng felt a little wrong.

Maybe it's been in the organization for too long, and Sky Wolf's feelings for Gu Sheng are a bit like a child, giving her the best things, just watching her smile.

is this kind of unrequited feeling, Gu Sheng is very frightened.

Because I can't respond to this kindness, I feel sorry for the person who paid.

Gu Sheng has never denied that he still has feelings for Lu Yuchen until now, and the past with so many vigorous memories is not easy to forget.

Even if he let it go, Gu Sheng only wanted to leave this organization, and then take Xiaobao with him, and the two of them would live the rest of their lives together, and there was no need for a third person to participate.

Therefore, Gu Sheng almost didn't think about other people's feelings.

Even if the wolf was like this, she knew she had no way to respond.

Gu Sheng ate something that had become cold, and it tasted a little better than usual, but she ate and chewed wax, which was really bad.

After eating, Gu Sheng forced himself to enter the work state and stop caring about those personal matters.

After all, other people's emotional things can be delayed again and again, but the time of the task is dead, there is no way to change and delay, if you are so distracted, the task fails, and the punishment is not necessarily on yourself, the most likely, it will be on Xiaobao.

Thinking like this, Gu Sheng finally settled down and started the work at hand.

A few hours later, Gu Sheng took the antidote that appeared on a large scale and looked at it carefully, just as she had imagined, there was still a problem in the last link.

The final ingredient is difficult to complete the reaction and may require other catalysts.

After working in the laboratory for a long time, it was not until Gu Sheng felt that he could not support his physical strength that he finally stopped his excessive workload and sat on the chair to rest for a while.

The things that replenish energy have been eaten, and the last time he ate was six or seven hours ago, even if Gu Sheng was reluctant to leave the laboratory, there was no way.

If this continues, not to mention whether you can research an antidote, or whether you can carry out the task, it is a question.

There was no way, Gu Sheng had no choice but to leave the laboratory, prepare to go back to the room to rest, and when he replenished his strength, he continued the research work at hand.

The time of the mission is the night hotel, in a bar, a good place to hide from people.

But Gu Sheng's antidote had not yet been developed, and when he woke up, it was already nine o'clock in the morning of the next day.

After washing up quickly, Gu Sheng ran into the laboratory again, quickly running his brain, and began to consult all kinds of books, trying to find a trace of his own use from other recipes.

Repeated failures, repeated repetitions, Gu Sheng's patience did not decrease a little, but became more and more calm, she was already on the verge of success.

The poison she had just developed a few days ago gave her a good inspiration.

Sure enough, in the last test, Gu Sheng came up with the final result.

Moreover, in the process of developing the antidote, Gu Sheng was even surprised to find that some of the ingredients in the antidote could better cooperate with the poison, resulting in its toxicity and effect being a few points better than before.

After configuring the antidote, she also put the new poison into a perfume bottle, pretending to be the item she was carrying, and Gu Sheng happened to get into the car sent to her by the organization.

There was only one driver in the car, and he was silent all the way, saying nothing.

It just so happens that Gu Sheng also needs a quiet environment, sort out her thoughts, and stabilize her mind by the way, this is the first time she has accepted such a task, and she must be careful in everything.

A failure is not only not killing a person, but more importantly, this result will bring even greater disaster to oneself.

Success, not failure.
