As soon as the car driven by Liu Jiajun, Meng Jie and others returned to the Houston Research Institute, Charles received a message from the other side of the gate.

"These guys are back, and they've not been in the harbor for long, so I'm afraid it's not easy," Charles said to the SRT team members who had gathered.

"It's good to be back, or I won't have a chance to settle accounts with them," Michio clenched his fists and his eyes widened.

"Don't act rashly, since these people have gone out and come back, there must be some purpose," Charles thought for a while, and asked towards Delong, "Is Zhang Wenzhuo's safety guaranteed?" ”

"No problem, it's guaranteed," Delon nodded.

"Next, everyone should pay attention when they go to mark people, the other party is not necessarily weaker than us, this is a lesson that Qian exchanged his life for us." Charles continued, "I've reported Rick's matter to Kelly, did you check his personal belongings and find anything?" ”

"There's nothing special to be found, and I can't find any trace of his contact with the Chinese side," Maggie said, recounting the results of her investigation of Rick, and then asked, "What does Secretary Kelly say?" ”

"He didn't say anything, but I could feel he was angry."

After Liu Jiajun returned to the delegation's residence, he did not go to see Pang Zhike with Zhao Kang and the others, but immediately began to prepare for his assassination of Zhang Wenzhuo. According to the plan discussed with Cai Wenyue on the Shenyang, the first step was to go to the building built on top of the underground bunker to step on the spot, and then he had to go to the arsenal of the research institute to find a way to get guns.

"Sniper rifle," Liu Jiajun locked on to the action tools he needed without thinking about it, and he studied the architectural layout of the institute according to Cai Wenyue's reminder, looking for a suitable location for using a sniper rifle around the building where Zhang Wenzhuo might be hiding.

Many of the buildings inside the institute are vacant, because the personnel inside are basically soldiers except for scientific researchers, and no survivors from the outside are allowed to enter here, so after several strict inspections at first, these vacant buildings are basically not inspected by anyone in normal times.

Liu Jiajun took the telescope to the vicinity of the target building, and after walking around there a few times, he chose an unmanned high-rise building with a good angle to enter it. It's not yet night, Liu Jiajun was very careful when he came, and avoided the sight of others as much as possible along the way. He came to the building, and climbed the stairs of the staircase, his ears vigilantly catching sounds other than the sound of his own footsteps.

The corridor is very quiet, Liu Jiajun's steps are also very light, although there are generally no people coming to such a building in the research institute, but he does not dare to take it lightly, because he learned from Cai Wenyue that there are many difficult opponents in the research institute.

Qian is not much of a threat to Liu Jiajun, that is because he did not use a gun, but used a dagger, and it just so happened that Liu Jiajun was also an expert in using daggers. The reason why Qian did not use a gun at that time was because he did not understand Liu Jiajun's ability, and secondly, he was somewhat affected by the constraints of his actions.

Liu Jiajun is well aware of this, and when he moves in the corridor, in addition to paying attention to the movement around him, he also pays attention to hiding his figure from different angles of the wall.

It is not easy for a sniper to accurately hit the target when shooting, and many people have the impression that the operation of a sharpshooter is to raise the gun and hit it with one hit, but in fact this is not the case, and shooting is far from so simple.

Ranging is a technical job and a very important step for snipers to operate before shooting. Liu Jiajun had completed the task of ranging before entering the building, and he obtained a relatively accurate result through distance measurement on foot and visual measurement, and then he had to find the most suitable observation point to further accurate the results, for which he brought some gadgets out.

The accuracy of the shot is not only affected by the results of the range, but also by the direction of the wind and the shooter's grasp of the advance of the moving target, and the top snipers will even perfect the details to whether the trigger is smooth and stable when the trigger is pulled.

The building where Liu Jiajun looked for the firing point was probably between 400 and 600 meters away from the target building, and the importance of ranging was especially important at this distance. If the distance from the target building is 200 meters ~ 300 meters, then the bullet he shoots at the target's chest can still hit the target if the range is inaccurate, but at the current distance, the bullet will fly over the target's head because of the inaccurate range.

The closer the distance is, the better it is for the shooter, but Liu Jiajun can't find those closer shooting spots, because he also has to think about getting out after shooting, so he has to leave a certain amount of advance for himself. If the distance is too close, the faster the other party will rush over, and it will be difficult for him to get out safely.

I chose a place near the edge, by the edge of the window of a room, the shutters on the windows were broken, the leaves on them were a little worn, and many of them were hanging down. The reason why Liu Jiajun chose this place is because these hanging blades can well shield the sniper rifles used when shooting, and this position also has a good view when observing the target building.

Once he had identified the firing point, he began to measure the precise distance between the two buildings with a rangefinder, which he could actually measure with his fingers, but that was a last resort in the absence of measuring tools.

After the distance between the buildings was measured, it was locked at 523 meters, and Liu Jiajun would add a little bit based on his own observations when actually shooting, because the target of the shooting was in the building, not on the wall of the building.

The target building was supposed to be one of the centerpieces of the Houston Institute, and Mr. Liu had seen signs of movement in multiple windows. His gaze gradually climbed up the wall, and suddenly his gaze flickered to see a familiar figure just flash through one of the windows.

"Zhang Wenzhuo! You're in there. Liu Jiajun's eyes suddenly became sharp, and he continued to observe the movement of the window with the rangefinder he brought, and finally confirmed that the room was Zhang Wenzhuo's temporary office area in the research institute.

After the observation, Liu Jiajun did not delay for another second in the building, he returned to the delegation and began to prepare the next step.

Next, Liu Jiajun needs to go to the arsenal in the base, which is a bit troublesome, because he not only has to sneak in, but also steal guns inside.

It is obviously inappropriate to directly use the weapons carried by the Chinese side, and this will not only leave clues, but also give the United States a reason to criticize the Chinese side. Liu Jiajun plans to use the guns of the Mi people to kill the traitors who have defected to the Mi people, so that there will be no clues, and even if the Mi side has any suspicions, no evidence can be found.

The problem of guns is not easy to solve, especially after Liu Jiajun killed Qian, he has already realized that the other party has begun to pay attention to himself. He thought about it, planned to schedule the operation at night, and was also going to disguise himself and change his appearance a little.

The location of the arsenal was at the other end of the institute, where it was manned around the clock. When it got dark, Liu Jiajun was already lurking nearby.

He had chosen the right timing, it was just getting dark, and it was just time to eat. The interior of the institute has been peaceful for a long time, and the soldiers will inevitably be lax in guarding these core areas, and apart from those delegations, there are basically only soldiers in the base except for scientific researchers, and there is no unstable factor among these people.

Outside the arsenal, Liu Jiajun observed that the guarded work of the soldiers was not very strict, and as the shift change was approaching, some soldiers had already hung the weapons they had held in their hands back on their backs.

The soldiers gathered in twos and threes chatting to pass the last bit of time before the shift, and those who were okay even smoked cigarettes.

Liu Jiajun glued a circle of beard on his face, he had observed that there were many guys who liked to grow beards among the soldiers in the base, and the beard could better cover his yellow complexion.

He crept to the side of the arsenal and slowly approached the building with the help of the surrounding plants. Most of the soldiers on duty inside had already gathered at the door, ready to take over the next shift with the next group.

This is a great opportunity, and Liu Jiajun is in the gap between them when they take over the shift, of course, this period is very short, but in Liu Jiajun's opinion, it is enough.

He's long been accustomed to dealing with dangerous things in tight times, and racing against time is the norm in his former career as a killer.

Liu Jiajun began to climb along a wall on the side of the arsenal, preparing to enter by relying on the air vents above. The building was not previously designed as an arsenal, it was convenient and modern as a civilian building, but it was somewhat unqualified as a military building, but it was selected as an arsenal due to the geographical location within the institute and a large number of arms were hoarded.

If it were an arsenal in the Mi Army's military base, Liu Jiajun would probably not have any idea of sneaking in, because the difficulty of doing so would be comparable to ascending to the sky.

The fan of the vent rotated slowly, and Liu Jiajun easily removed it, and then he climbed in along the pipe, and as he climbed, a stream of hot air caressed his face.

Because of the heating, the temperature inside the arsenal was not as cold as outside. Liu Jiajun learned about the internal layout of this building from Cai Wenyue, and also knew where the guns he wanted would most likely be placed. He climbed down the pipe all the way in, and was ready to drill out at a suitable spot.

The shift was already changing at the door, and the soldiers of the other squad had come to the door of the arsenal, they had already eaten dinner, and now they had officially come to replace their comrades who had been on duty to rest.

The arsenal was empty all of a sudden, Liu Jiajun mentally estimated the time, and after he got out of the pipe, he went straight to the room where the sniper rifle and other weapons were stored.
