Under the cover of the rain, Li Sa quickly recovered the steel cable, and then used the balcony railing of this building to climb up layer by layer with flexible and vigorous skills, and it took nearly forty minutes for him to climb up to more than a dozen balconies, and finally climbed to the roof of this building.

Li Sa didn't choose this building randomly, it was precisely because this building was the building with the most floors in this base that he would aim here.

After ascending to the highest rooftop in this base, it means that the commanding heights are completely controlled by Li Sa, so he immediately quickly located the target building according to the information provided by the stinger, and then used the high-powered telescope to lock on the floor where the target person is located and conduct ambush observation.

It has been raining heavily in Geneva, Switzerland, on this night, and Li Sa has been holding on to this heavy rain all night, thus officially locking in his target.

On the next day, Li Sa still hadn't made any new moves, he carefully observed the surrounding environment and the guards, and also mastered the law of their handover.

The target of his mission is Colby, the director general of the Shijie Health Organization, and Stinger suspects that the reason why the Black Brigade was able to successfully steal and cultivate incomplete genetic cells was because of a traitor in the top of the Shijie Health Organization, which belongs to the United Nations.

And Colby was one of the main people in charge of this gene cell cultivation jihua before, and if he had formed some kind of cooperative relationship with Defiya, then it was also under his control that the Black Brigade would deliberately let the Black Brigade successfully steal this gene cultivation in the United Nations Health Bureau.

Therefore, before Stinger asked Li Sa to assassinate this Colby, he was able to get evidence of his betrayal of the United Nations.

Li Sa lurked on the roof of the building all day, and after deciding the best route to get out of here, he patiently waited for the night to come.

Fortunately, he had been injected with nutritional injections to provide energy to his body before the operation, so for the past two days, his body basically did not feel hungry.

Although this kind of needle cannot be injected too much, and it will slowly accumulate sequelae of the body, it is the most convenient kind of nutritional injection for the assassin.

Finally when night fell, Li Sa saw the opportunity and decisively chose to start the action.

I saw that he continued to use the method of zipping by tightrope, and unknowingly slid down from the roof of the tallest building to the building where Colby was located, and he slid very directly from the balcony of the room where Colby lived.

At this time, Colby in the house did not realize that an assassin had arrived on the balcony of his room.

After Li Sa determined that the target he wanted to assassinate was in a house a few meters away from him, he immediately deliberately made some suspicious small movements on the balcony.

Although it was not raining at night, the night wind was still not light.

Colby thought it was the wind blowing at first, but he was also suspicious by nature, and he couldn't help but walk to the balcony to make sure that it was the night wind.

Li Sa, who was hiding in the dark on the balcony, saw that Colby was really about to open the bulletproof glass door on the balcony, and couldn't help but admire the information written by the stinger in the miniature USB flash drive.

This man really has a ghost in his heart, otherwise he wouldn't have been so cautious and so cautious.

At the moment when Colby opened the door, Li Sa, who was hidden in the dark part of the balcony, made a very decisive move, and directly reached out and pinched Colby's chin first, preventing him from making an extra sound.

Immediately afterwards, Li Sa pressed most of Colby's body out of the railing of the balcony, and as long as he let go, the man would definitely fall from these dozen or so floors.

"Do you really think you're doing something that you don't know?" Li Sa said to Colby in English in a low voice, of course, these lines are all designed by Stinger for a long time, specially designed to fool people.

In order to allow Colby to be able to speak, Li Sa specially changed the action of pinching his chin to choking his throat, so that he could take his life at any time, and he was not afraid that he would dare to make other movements casually.

Colby really didn't expect someone to assassinate him at such a time, and from the look of shock and fear on his face, he knew that he had actually expected such a day sooner or later.

"I don't know what you're talking about...... Colby replied tremblingly, intending to pretend he didn't understand anything.

Li Sa has been an assassin for so long, and all kinds of cunning characters have seen him, how can this man deceive him.

He immediately increased the force in his hand, tightened Colby's neck even more, and said in a tone full of murderous intent: "Madame said that you have been hiding here quite comfortably lately, so she sent me over to see you." ”

Li Sa's words are also the lines arranged by Stinger, which is the information that he learned from Xiao Kai before, plus Li Tian's intelligence was sorted out by Stinger.

Sure enough, after hearing Li Sa's words, Colby's attitude was completely the same as just now, and his extremely nervous nerves didn't think much about it and believed that Li Sa was sent by Defiya.

So he immediately said with a frightened look: "Help me tell Madame, I can't do anything else for the time being." Because of the fall of the United Nations Headquarters, the internal organization is now very tense, and I can't provide information casually......"

Hearing Colby's words, Li Sa almost couldn't help but strangle him directly, but he didn't expect that this high-level United Nations cadre was really working for the Black Brigade, a terrorist organization.

"Madame said that the secretary general was not there at all, so she ran away in vain." Li Sa once again said that Stinger had already designed haode lines.

When Colby heard this, his legs suddenly went limp: "I didn't know that the secretary general would evacuate so quickly...... He had indeed returned to the Secretariat building and had a meeting......"

When Li Sa heard what he said, he thought to himself that the director general of the Shijie Health Organization seemed to have revealed the whereabouts of many secretaries-general to the people on the Black Brigade.

All of this was really as Stinger expected, which suddenly made Li Sa admire the man Stinger even more, but he didn't expect that even if he was not at the scene, it seemed that he had rehearsed these pictures and dialogues in his mind.

This Colby was panicked, and at a glance he knew that his nerves had been tensed to the extreme, so he didn't realize that he had completely fallen into Li Sa's language trap.

"Then I'll ask you again." Li Sa's voice was even darker than just now, "Did you provide that virus to Madame?" ”

Colby didn't answer stupidly this time, because he quickly heard that something was wrong with the question, so he immediately asked rhetorically, "You want to ask such a question?" ”

"Because I want to know if the man who committed the unpardonable mistake of the crime is you." Li Sa gritted his teeth very unceremoniously and replied.

Colby's face immediately changed: "You, you...... You're not from the Black Brigade?! ”

"It's a pity." Li Sa snorted coldly, and when he found out that Colby wanted to shout loudly, Li Sa took the lead and squeezed his throat, making him completely unable to make a sound.

"My chief hated the human race who betrayed his faith, so he sent me to kill you, so that you would not waste your time living on this shijie." Li Sa kindly added this sentence again, "Good night, Mr. Colby." ”

After saying this, Li Sa no longer gave Colby a chance to speak, and directly cut his throat with a quick knife, and started very neatly.

Things went much smoother than he had imagined, which made Li Sa feel that this Shijie Health Organization might have already become a puppet used by the Black Brigade.

Therefore, they are not afraid that those terrorists will attack here, so they dare to be so fearless, and even the level of guarding and guarding is not half the level of their northwest military base.
