After thinking about it for a while, Li Feng decided to take action, he couldn't sit here and wait for death, since the viper didn't want to help him rescue the doctor and Devil Six, then he could only go to the laboratory where the doctor was now to be a miscellaneous person, and only in this way could he protect the doctor's life and Devil Six's life at close range.

After making such a decision, Li Feng came to the viper without the slightest hesitation.

"I hope you're helping me with one last thing, and I won't use the antidote to blackmail you anymore."

The poisonous snake looked at Li Feng with a frown.

"I hope you're telling the truth."

Li Feng did not hesitate, and quickly told the poisonous snake what he thought in his heart, although when he heard Li Feng's idea, the poisonous snake's face was full of confusion, but after thinking about it carefully, he agreed, but also advised Li Feng not to do any more sabotage in the laboratory, otherwise no one would be able to save him.

Just as he was about to go out, the viper suddenly stopped.

"When will I get the antidote?"

Li Feng pondered for a moment, the latest information he got from Commander Lan Kun was that they would definitely break through this research institute within three days and rescue Li Feng and Dr. Liuhe.

"I'll give you the antidote in three days."

When he got such a news, the poisonous snake glanced at Li Feng deeply, and then didn't say anything, as a poisonous snake, he naturally knew very well that this research institute could only support three days.

Although it is not clear how Li Feng contacted the outside world, but how much this has to do with them, as long as he can get the antidote in Li Feng's hands, as long as it does not violate the conditions of his life safety, then the poisonous snake does not want to care about anything.

In fact, Li Feng still underestimated the energy of the viper in the entire research institute, and when the viper walked out less than two hours later, he returned to the cabin again and told Li Feng that he had arranged it properly, and Li Feng would become a person in the laboratory to help the doctor give the doctor.

Li Feng was secretly happy in his heart, as long as he could enter the laboratory, then once the doctor or Devil Six encountered any dangerous situation, he could help, instead of staying here, like a fish on a chopping board, silently waiting for the final result.

"When can I go?"

The poisonous snake drank a glass of water and sighed secretly, if it weren't for the fact that his life was still in Li Feng's hands, then he would definitely not go against the distant group.

After staying in the distant group for such a long time, he already knew what kind of fate the big boss behind the scenes would have when he dealt with the traitor, and only hoped that Li Feng could achieve his goal as soon as possible, give him the antidote when the time came, and leave quickly.

"If you want to go now, then you can too."

Since he had such convenient conditions, Li Feng did not make any delays, and quickly asked the poisonous snake to take him to the laboratory to be a qualified helper.

Li Feng's personnel changes did not cause much of a sensation in the entire research institute, and no one noticed Li Feng's existence.

Except for the mercenaries, all the scientific researchers have been suppressed by the army that is constantly gathering outside the research institute, if it were not for the suppression of the head of the research institute, I am afraid that they would have left this research institute long ago and fled for their lives, at such a moment, no one is nosy.

Devil Six's expression was still so wooden, except for a slight hint of light when Li Feng came here, he always maintained such an expression, and he couldn't let people notice any difference.

Li Feng used tactical language to tell Devil Six to wait silently, and he would definitely be rescued within three days, and he should not make other small moves in these three days.

After doing all this, Li Feng lowered his head, showed a very respectful look, came to the doctor, and began to help the doctor dispose of some discarded chemical raw materials.

Although he has some involvement in chemistry, he has only learned a little bit after becoming a special soldier, and he can't figure out the big stuff in front of him at all.

Fortunately, this doctor didn't really want to make what he created for the people of the distant group, so even if Li Feng stood there motionless, he wouldn't say anything, and he would be idle.

At this time, the doctor didn't know that Li Feng was actually here to rescue him, so when he was in a bad mood, he would take Li Feng's two sentences out of anger.

Li Feng didn't care about the doctor's behavior at all, he came here just to be able to let the doctor in front of him return to China, as for being misunderstood, or having other grievances, it was nothing.

Originally, Li Feng thought that during these three days, there would definitely be the person in charge of the research institute to urge the doctor to get what they wanted, but in the three days, Li Feng did not see any responsibility at all.

At this moment, Li Feng clearly realized that it should be the poisonous snake that blocked the news and did not let anyone disturb the doctor, otherwise it would definitely not be clear why the person in charge of the research institute would not come to trouble the doctor.

Since there was no one to disturb him, Li Feng was also happy to be idle, but Li Feng felt that he still had to prepare a little, and the thing he fed to the poisonous snake was just a very ordinary cold medicine.

If you use something like cold medicine to fool the poisonous snake, I am afraid that it will not work, the best way is to do some disguise, neither let the poisonous snake know what its real function is, nor let the poisonous snake think that Li Feng is lying to him.

Fortunately, Li Feng inadvertently mentioned that he wanted the doctor to get him a medicine with more complex ingredients, and it was better to add some laxatives and other ingredients.

Since he didn't come to urge the production of those important things, the doctor was also happy to be idle, and agreed very happily, and handed it over to Li Feng one day.

Holding the medicine in his hand, Li Feng secretly breathed a sigh of relief in his heart, for the poisonous snake Li Feng actually wanted to destroy it humanely.

But because he promised to spare his life, Li Feng had to spare him this time and wait for the next time, when he saw the poisonous snake, then it would be the death date of the poisonous snake.

On the night of the third day, the army outside attacked this research institute in all directions, even if these mercenaries fought to the death, but there was no way to resist the defeat of these regular troops.
