It didn't take long for the three members of the Emergency Response Team to come to an agreement and decide to enter the castle.

No. 3 is right, Zhang Heng took the initiative to give up the maneuver and switch to the defensive battle, which is actually equivalent to giving up his greatest advantage, it is a once-in-a-lifetime opportunity for them as opponents, there is no reason not to seize it, but the three of them are also very clear that the reason why the other party will make such a decision must have their own reasons.

Therefore, before entering the castle, all three of them did a lot of preparation, especially noticing the smoke drifting through the castle, equipped with thermal detectors to deal with this environment, and also keeping an eye out for possible traps in the castle.

However, they obviously thought too much about the latter point, the reason why Zhang Heng gave up guerrillas, except for the fact that there were only two bullets left in Bartlet, the most important reason was actually very simple, he just wanted to end the battle in the shortest possible time.

Compared with a sneak attack in an open space, the danger of fighting in the castle is indeed higher, but it saves the link of seeking the enemy, and it can also save more time, which is very suitable for Zhang Heng who is in a hurry to get back to the station.

…………

After getting ready, the thirty people on the side of the Sheng Tang Morgan cautiously touched into the castle.

They formed a team of six people, a total of five teams, separated by about three meters from each other, so that they could not only prevent the bomb trap from breaking through, but also quickly support each other in the event of an accident.

In addition to the one thermal detector carried by the No. 2 emergency response team, the other two federal police squads were also equipped with one each, according to the regulations, and the commander No. 8 redistributed the three thermal detectors, of which the leading team had one and was responsible for finding the way, and the team following them to the right also had one in its hand, which was responsible for supplementing the dead spots that the team had not detected before the detection.

As for the last one is still in the hands of No. 2, there is no requirement for this thermal detector No. 8, basically let No. 2 observe freely, although the thermal detector can only detect a distance ahead, but the three are used together, and the coverage area is quite wide.

As the first group walked into the castle, there was no gunfire inside, the castle was quiet as if no one existed, and nothing was found on the thermal detector, and then the second group followed closely behind, cooperating with the first group to keep watch...... It wasn't until the fifth group also crossed the gate that all thirty of the Tang Morgan entered the castle.

Whether it was the first and second groups that went first, or the No. 2 who followed behind, there was no trace of Zhang Heng for the time being.

Commander 8 and two teams of federal police conducted a general search of the first floor, and after confirming that it was safe, they moved towards the second floor.

As with the previous strategy, it was still a group of people who took the lead in front, and the rest of the people kept the interval and followed behind, but this time the first group of people just turned the stairs, and the gunshots rang out, and a federal policeman in the lead was directly knocked to the ground by this shot, but fortunately, the plainclothes of the previous three disguised emergency response team members were also wearing the latest generation of bulletproof clothing, and one of them took off the body armor and let the federal police officer who walked in the front wear it, which saved the latter's life.

His companions then took the risk of dragging him back, and the crowd began to shoot back as they scattered to find cover, while the other side unceremoniously shot at them.

For a moment, there was a lot of gunfire in the hallway.

However, after a while, the three members of the emergency response team sensed that something was not quite right.

No. 8 gestured to the federal policeman who had been walking in front of him and asked the latter if he had seen Zhang Heng before, but the federal policeman said that the smoke in the corridor was too loud, his vision was very obstructed, and he was hit by a sniper rifle as soon as he turned the corner.

However, the thermal detector in his hand still reacted, showing a figure at the other end of the hallway, but this statement did not reassure Number 8, but made him feel more uneasy, and then he signaled everyone to cease fire and retreat to a place where they could not be seen on the other side of the hallway, but the gunfire on the opposite side did not stop there.

At this time, the three people of the emergency response team have already determined that they are being calculated, if it is an ordinary person in a tense situation, it is possible that they will not be able to control themselves and fire wildly, but for a master like Zhang Heng, it is obviously impossible to make such a low-level mistake, and don't look at the lively fight between the two sides before, so far, the top of the team is only the group except for the guy in bulletproof clothing who was hit by a sniper rifle, and the rest of the people are still alive.

No. 8 is not looking down on the ability of these federal police, but compared to Zhang Heng, their strength is not enough to support this evenly divided battle.

"Let's see what's going on." The one who opened was No. 3.

Nodding his head as well, the three of them called the other three federal police officers and touched the hallway again, this time because they were close, and the three members of the emergency response team also heard more details from the gunshots, including some ambient sounds that did not match reality.

"Recording?" Opening 3.

Immediately after that, No. 2 also found that the humanoid target in the thermal detector was actually motionless, and later No. 8 sent two federal police officers to walk cautiously, and finally found the inflatable thermal inducer there at the end of the corridor, as well as a voice recorder next to it.

No. 8 immediately thought of something, and his face changed, "Everyone, come and meet me!" ”

After counting the number of people, the cold sweat on the back of No. 8 flowed down, he didn't expect that in just such a short period of time, his side would quietly lose ten people, and the two missing teams were standing at the back, because they had checked the first floor before, and confirmed that Zhang Heng was not here, plus the battle mainly took place in the corridor, and the three people of the emergency response team didn't pay much attention to the situation behind.

They didn't expect Zhang Heng to play a hand, when the previous shot sniped the target, Zhang Heng was obviously at the end of the corridor, but then he used the recording and heat inducer to deceive everyone, attracting everyone's attention to this corridor, and he himself didn't know how to quietly dodge the three thermal detectors and went around to the first floor.

When No. 8 rushed back to the first floor with his people, he only saw corpses on the ground, and the fatal wounds on their bodies were all knife wounds without exception, and they were killed by one blow, without any chance to struggle or shout for help.
