The tactics were redetermined, and the departments began to get busy, and only two or three people were left in the conference room to continue talking.

"Brother Dog, Nie Kong ...... today" The person in charge of the minutes of the meeting hesitated, "Why do I feel that he seems weird?" ”

"Huh? Have it? The old dog smiled casually, with a cigarette in his mouth, but the expression on his face was not relaxed, and then he said calmly: "Say less and do more, and be busy with your go." ”

"Oh......"

Yan Lao didn't leave at this time, he still sat on the chair next to him, and looked at the old dog for a while, the two didn't speak, just made eye contact for a while, and finally, the old dog shook his head, and Yan Lao nodded.

How tricky is the eyesight of the veteran agent, if Nie Kong was just an excellent combat agent before, then he was strangely a little bit of a decision-maker at today's meeting.

Including his gestures, every demeanor and eyes have changed his temperament.

This kind of change should not be caused in a short period of time, and the old dog had already seen something at the meeting, so he directly stopped Qin San's speech.

He was worried that Nie Kong's change would be negative, or potentially threatening, but this operation was too critical, so he decided not to trigger what was in Nie Kong's heart before this operation.

……

As night fell, the 69th Division outside the city divided a unit to divert most of the insect tide, and the main force launched a rapid march by semi-latent means, came to the north of Chang'an City, and began a full-scale siege of the city.

The sound of artillery fire was deafening, the entire night sky was illuminated by the constant light of fire, and the air was filled with acrid smoke, and this scene stretched beyond most of the northern city walls.

The existence of the Chang'an city wall, originally intended to prevent insect tides, the wall material has outstanding anti-corrosion and anti-climbing ability, if the built-in magic energy device is activated, it can also maintain a magic energy shield for up to two days in the whole wall, and if only one side of the city wall is defended, it can maintain a shield defense for more than a week.

The entire city wall has a machine-gun firing hole hidden every five meters, and in the night sky, the sprayed tracer bullets form a light curtain, and the shelling holes on the upper floors burst out with a continuous roar, and the ammunition is undoubtedly very sufficient.

More than 300 anti-aircraft cannons and surface-to-air missiles were deployed on the top of the north city wall, and a huge black-armored awakened person stood solemnly with his hands down, and the black pressure was connected into a line to the distance, and the fighters of the Secret Service were busy running around, and red robes could be seen everywhere.

Chang'an, as a frontier area, surrounds the entire city wall is almost a small Great Wall, with a wall 17 meters thick, and the interior is not only placed with countless external defensive weapons, but also can be said to be a military fortress connected into a 'mouth' shape.

This fortification was started after the last insect attack, which was a major event in the whole country at that time, and when it was completed, it was called a new world-class military fortress by foreign media.

The 69th Division has a mobile artillery regiment, but the continuous fire suppression they can give cannot be compared with the city defense system of Chang'an.

They were waiting for a signal.

At the same time, a small group of only thirty men was slowly approaching the northern wall, each of them invisible, and the guards of the wall were completely unaware of them.

At present, the Second Special Operations Group has three sets of stealth methods, but with the blessing of Nie Kong's 'Phantom March' upgraded 'Hundred Ghost Night Walk', there is no need to use other schemes in the initial infiltration stage.

Enhanced Hyakki Night Walk LV7 (Passive/Active): The passive state can make more people enter the intermediate invisible state, and it will be revealed when moving quickly. After activating the skill, it can enter the advanced stealth state, which lasts for 24 (20) seconds, during which it increases the movement speed of the troops by 30% (25%), and the first attack of the troops after removing the stealth comes with the intermediate horror fantasy effect, the cooldown time is 1 minute, and the skill is more effective at night. (Values in parentheses are before strengthening)

The north city wall is the defense center of Chang'an, and the detection means are naturally not simply guarded by personnel, but all the confidential information of the city wall is in the hands of the original military in the north of the city.

But Nie Kong and his party didn't dare to be careless, and it was likely that the Secret Service had changed the internal defense deployment of the city wall.

An agent stood at the base of the wall with a detection device, Nie Kong stood by the side to maintain the group hidden, and the group behind him looked vigilantly left and right.

"We've been able to confirm that there's a gas detector behind the wall, and its range is 20 meters, so you can't get through, so let's go to Entrance 3." Zhang Maonan's voice came from the voice channel, and hearing her words, Nie Kong and his party immediately began to transfer.

The best equipment for detecting stealth units is the Gas Detector and the Ground Pressure Detector, which combine to make even advanced stealth effects easy to obtain.

The original plan was to blossom at two o'clock and force Qi Yue to issue an order to the awakened, in order to prevent him from becoming alert, Nie Kong could not appear in both places. He came with the team to escort the team on a sabotage mission, and after reading the soul of the first Awakened One, he had to make his way to the second target point without leaving a trace.

The team came to the third entrance, and stood no more than ten meters next to the two guards to carry out the detection operation, and after discovering the detection equipment used here, the technical team quickly determined a safe infiltration route according to the scope of action of these equipment.

"There is infrared surveillance on the left hand side of the door, and there is a person at the door of the room on the right hand, a floating island, you shouldn't be able to let three people fall into a fantasy at the same time, right? Then let's move on to Entrance Four. ”

The floating island has a difficult color, and it seems to be thinking, but it does not respond immediately.

This is also the biggest problem in the infiltration mission, no matter how powerful the stealth ability is, it will also face a closed door, as long as there are guards staring at the door, it is impossible to sneak in. Only the illusion spell can make the guards unable to see the open door and hear the sound of the door opening.

But there were already two guards staring at the outside of Entrance 2, and there was actually a guard inside. Once the door is opened, the illusion magician has to use the illusion to confuse three people at the same time, and the average illusion master can't even do the instantaneous illusion of one person, let alone deal with the current situation.

"I'll deal with the two outside, can you confuse the one inside the moment you open the door?" Nie Kong suddenly asked.

The members of the action team stared at him in astonishment one by one, of course, they had to remain silent throughout the whole process when they infiltrated the operation, not to mention that there were guards within ten meters of him, Nie Kong actually spoke directly!

However, when they looked at the two guards, they found that they were still staring indifferently into the distance, and they didn't seem to hear a sound at all.

A full-fledged illusion is naturally impressive, and the illusion caster can also process and package the sound, or erase it.

Floating Island glanced at Nie Kong in surprise, with his expertise, he quickly found that this was an illusion spell at work, and then nodded heavily.

"Alright, let's get ready."

Nie Kong is now very familiar with the illusion, it is difficult for ordinary illusion magicians to use illusions in actual combat, and they want to release the illusion on the guards inside the moment they open the door, making him think that the door has not been moved, and the novice illusion magician even needs to see the scene map inside the door in advance, and prepare for a long time before casting spells.

The floating island did not ask for this, apparently he had already passed this level.

The human eye will only focus on one point, except for the object of his attention, the other scenes in the field of vision are blurred, as long as there is little change, they will not be noticed.

The illusion magician at the level of the floating island can already instantly create a simple illusion, and the illusion spell can be used in actual combat.

In the face of the task situation at this moment, conjuring a fly flying in front of the guard's eyes can greatly reduce the pressure of the illusion at the door, and it can even be said that as long as the color of the door is roughly simulated.

The access control system at the second entrance of the north city wall was also complicated, but Erte was already very familiar with this system, and this was not a problem at all, and two minutes later, a living team of more than thirty people entered the well-defended city wall under the noses of the guards.

After all entered, the group immediately divided into three teams, Nie Kong took ten people to the magic energy control center of the entire city wall, and the others divided into two teams, using concealment methods, to perform other tasks.
