As Ye Wenqin's instructions were conveyed to everyone's ears, several faint gunshots rang out. Guns with delicate mufflers hit targets that had already been chosen by everyone from all directions. The heads with smiles on their faces were immediately opened with several large holes, and the agents of the Blackbird Office who were assigned to be on duty were immediately killed on the spot.

"The technical level of the Chuck Federation is really good, although we also have good mufflers, but they are all spiritual equipment, and we are still studying this kind of technology that relies solely on pure physical means to silence sound. Angelina and Armstrong, who have been on the front line of the battle for a long time, have gone from initial surprise to numbness to the new equipment on the Chuck Federation agents, and they are also envious after seeing this new type of muffler.

Although the intelligence departments of the two countries have strengthened exchanges over the years, it is the first time in these years that such a coordinated operation has been carried out, and the coordinated actions that go back to the past are even the things that happened when Zhuge Wenxian was young, plus they have hidden their good things before, resulting in the CIA not being clear about the level of combat equipment of the Federal Department of National Security, and even looking down on it, after all, the Silver Eagle Republic, which is firmly in the top spot of freedom and glory, has basically led the technology in all aspects in its history for hundreds of years.

In the past two years, the Chuck Federation has made great strides in airship technology, and the technical level of various related equipment has been continuously improved, although it has also attracted the attention of the Silver Eagle Republic, but it has not been too concerned, until this trip to the Federation led by Katarina, the high-level of the Republic realized that this little brother country that is located in a corner of the continent and has become stronger and stronger in the wars with neighboring countries in recent decades has developed so rapidly and vigorously, and has caught up with or even surpassed the technical level of the Silver Eagle Republic and the Astor Empire in many fields。 It is this rapid increase in strength that has allowed the Republic to truly understand this country, and will also make the status of the Chuck Federation continue to rise in the minds of the high-level of the Republic, and has surpassed several traditional allies of the Republic and several secondary powers of freedom and glory, reaching the second position in the Union State.

This cooperation with the Chuck Federation is also a practical test of the Federation's operational, organizational, and technical strength. Anyone with a discerning eye can see that the troubled times are coming, and at this time a reassuring ally is very important, in the recent private exchanges between Amelia and Katarina, they believe that it is completely impossible for the Hartland Kingdom, a neighbor of the Chuck Federation, to stop the growth of the Federation, and now the Chuck Federation has not eliminated this centuries-old feud, on the one hand, because on the one hand, if this kind of war of destruction is really adopted, the Holy Alliance will not ignore it, and even say that the Freedom Radiance may oppose this kind of thing that may provoke a full-scale war, and on the other hand, there is no idea of using the existence of the Hartland Kingdom to sharpen its own strength, to maintain the ability of the federal army to maintain its own combat capability and level in small-scale and low-intensity operations, and to constantly test new combat equipment and new tactics derived from it through combat. Of course, this is only a guess on the part of the two of them, and there is no way to know what it is, but this does not prevent them from asking McLaughlin to give the federal agents equal status in this joint operation, and even attach great importance to the ideas and opinions of these agents wearing strange masks.

"If you like it, let your director place an order, this kind of equipment is not within the scope of our export control. Ye Wenqin said to the two with a smile, now he is not at all like a commander in battle, more like a salesman with a green light in his eyes to promote his products, trying to take out the money from the pocket of the "big customer" CIA.

"Please, Colonel Clown, your wallet is almost wiped out by you, and if there are any other good things, let's take them out in one piece, this little bit of pulling out really knocks out our budget, and we can't buy the things in the back. Angelina pretended to be angry. But what she said is also good, in the past two days, Cleveland and Miramar and Weihandi have been very successful in the operation area, in which the special operations equipment that emerged from the Federation has allowed these federal agents who were originally working together to steal the limelight of the CIA, and also let the CIA's forward commanders continue to send McLaughlin applications for the purchase of new equipment, and the purchase application issued by McLaughlin in the past two days alone has made the federal personnel in charge of communication smile, although due to the particularity of the equipment, the number of purchases is not large, but this cannot stop this monopoly consumption, and the federal sales price is highIn just two days, the research and development expenses of these equipment have not only been earned, but even made a lot of money. This also caused these commanders of the front battles to receive orders from the rear one after another, demanding that new equipment be fully displayed and equipment sales increased, and of course, at the same time, there were also commendations, not only in honor, but also in material. This made the agents who received these orders a little crying and laughing, but they were all more hurried, racking their brains to develop new uses of these equipment, and a lot of various uses also emerged, even Ye Wenqin, who participated in the finalized development of these equipment, had to sigh how big these guys' brains were.

In the midst of the laughter of several people, several separate buildings have been occupied by them, and the first phase of the operation has been successfully completed. The Clevelands in the underground didn't know anything about it, and the commanders, Delise and Lindrod, were even sweating profusely there. Moreover, there were still two hours before the change of the guard, so Ye Wenqin and the others had enough time to arrange the second phase of the operation.

"The second phase is ready to begin, and it is up to everyone from the Federation to attack first. ”

At this time, the commander in the communication system has been replaced by Armstrong, he and his team members continue to perform the duty of monitoring the whole field, and Ye Wenqin, Nightingale and Angelina and others have joined the attack sequence, and they are also the main executors of the next attack.

As soon as Armstrong's voice fell, more than a dozen grenades that had been activated were thrown into the ventilation ducts of the underground base, which had also been guarded before, but they had become corpses, in order to prevent the people inside from discovering that something was wrong, these corpses had been opened, and sprayed to eliminate the smell, in case the Cleveland agents underground smelled the blood here.

The grenades that rolled down the pipe made a ping-pong sound when it came into contact with the pipe, and although the Clevelands were asleep, it was only a light sleep, and the sound quickly woke them from their sleep. The experienced ones immediately realized that something was coming in through the ventilation ducts, and it could never be an accident, knowing that there was someone guarding the outside. There is only one explanation, and that is that the enemy is coming, and in their experience, what is thrown in at this time is usually bombs or smoke bombs.

The first thing that came to mind was Acrylic, he didn't fall asleep like the rest of the team, but was exercising in the gym here, he had been stuck on the threshold of advancement for two years, although this fitness method did little to help him grow in strength, but he still maintained four or five hours of high-intensity exercise every day as long as he had time. He had just finished a set of iron, and he clearly heard these sounds, and immediately sent out the signal of "enemy attack". The Cleveland agents, who slept in their clothes according to wartime regulations, immediately jumped out of bed and rushed towards several passages, ready to meet the enemy who could rush in at any moment. There was immediately a burst of people in the stronghold, and the only thing that did not move was the core area where Dilis and Linderod were located, the two of them were in high spirits at this time, and even in order to prevent the sound from coming out, they also set up a small soundproof barrier, so they did not hear the abnormal sound of the ventilation duct and the warning sound of acrylic. However, because the people outside are also more flustered, no one has noticed these anomalies yet.

Although the Clevelands had outpaced their training syllabus, they were no longer able to stop the combined attack of elite CIA and Department of Homeland Security. Instead of the bombs or smoke grenades they had expected, the grenade-like objects that were thrown in did not explode or emit smoke, but instead emitted a faint hissing sound.

This is a powerful hypnotic bomb that has been improved by the chemistry department of the two major colleges of Chuck in accordance with the feedback of the previous skeleton brigade in the hostage robbery operation, it removes the effect of releasing smoke, but increases the emission and concentration of hypnotic gas, which can make the hypnotic gas diffuse into the air in the fastest time and ensure its effect, even the combat power in the early stage of the immortal realm will be seriously affected, at least the action and reaction will be stiff, or the heavy will also fall unconscious and lose the ability to fight, not to mention the enemy below the immortal realm。

The first to be hit were the four or five agents closest to the vent of the ventilation duct, they were putting on a defensive posture to prepare for the impact of the explosion, when the hypnotic gas came into contact with them, they didn't even snort and fell to the sky, one of them was even a master in the middle of the Vajra Realm, and was already the captain of several squads.

Someone fell five or six meters in front of the acrylic, and he immediately realized that what was thrown down would make them unconscious, although he didn't know what it was, but he could still guess it in general.

"Hold your breath, envelop your whole body, and ventilate the duct in principle. ”

He immediately shouted, and as soon as he finished shouting, he flashed backwards, and closed the pores of his body, and kept silent, and the powerful spiritual power like iron gushed out from his body, and even formed an armor-like barrier outside his body. It's just that he still underestimated the speed and effect of the hypnotic gas, and a trace of gas had already penetrated into his body at the same time as he opened his mouth, and began to affect his brain and nerves.

As soon as his backward body landed, he felt that his body was weak, and he couldn't lift up his strength at all, and even a strong sleepiness emanated from his mind, and a pair of eyelids became heavy and abnormal, as if he might fall asleep at any time. This is also thanks to the strength of his body, and the general half-step immortality is estimated to have been stacked down.

At the same time as he signaled again, seven or eight Cleveland agents fell to the ground one after another, plus the five who had fallen before and the guards who had been eliminated, and the fighters in this stronghold lost a third of their combat strength before they could see the enemy. As for the rest, they were all cautious, for fear of being affected by the attack that they had not yet understood. It's just a bit ironic that the barrier set up by Dilis effectively blocks the hypnotic gas from entering, and there is neither explosion nor smoke, so that the two of them still don't realize what happened.
