At that time, the poisonous snake will definitely send someone to find him, and Zhang Yu needs to prepare in the dormitory in advance.

So, Zhang Yu returned to the third floor from the roof.

Sitting down on the stairs on the third floor, Zhang Yu quickly modified the grenade he found.

Zhang Yu made every three grenades into one mine, used a thin line to pull the mine's string, and placed it on the stairs on each floor.

The mine is hidden at the rightmost right of the stairs, and the thin line connects the railings to the leftmost farthest.

As long as someone touches a thin line, the thin line will pull the strings that have been tied to the mine.

The mines will explode at that time.

Unfortunately, Zhang Yu did not have a remote-controlled detonation device in his hand, so he could only set up this original method of starting mine explosion.

Otherwise, Zhang Yu could have done the ambush trap better.

After setting up each staircase, Zhang Yu returned to the roof.

It's time to take the next action.

Zhang Yu lay in front of the sniper rifle, aimed at the sniper on the second floor of the warehouse compound opposite, and pulled the trigger.

"Bang!"

With a gunshot, the scope on the sniper rifle used by the opposite sniper shattered.

As the sniper lens shattered, the sniper collapsed to the ground with weakness.

"There are enemies! There are enemies!"

The killers outside the warehouse heard the gunshots and raised their guns to guard them, looking for Zhang Yu's location.

After killing the first sniper, Zhang Yu pulled the bolt of the sniper rifle, put the bullets back on, and looked for his next target.

"Don't be messed up, don't be messed up!"

The poisonous snake, driven out of the warehouse by gunfire, hid behind the box covered with canvas, and directed loudly.

"Secret, concealed!"

After hearing the poisonous snake's words, the killers hid in the bunker in an orderly manner, and for a moment, no one stood in the open in the entire warehouse compound.

"Go, go up and see the wound on the body, and see where the person is."

Zhang Yu fired a shot, and the poisonous snake was not present at the scene when the shot was fired, so it was impossible to judge Zhang Yu's location.

Now the Viper can only send someone to check the sniper's wounds to judge Zhang Yu's location.

"clear."

The killer beside the poisonous snake nodded and was about to run to the stairs behind to check the corpse of the sniper on the second floor.

However, the killer's figure had long been locked in the sniper lens by Zhang Yu.

Why, do you dare to act like this under my sniper rifle and look down on my marksmanship?

Looking at the killer in the sniper lens, Zhang Yu locked him and pulled the trigger without hesitation.

"Bang!"

A bloody flower broke out on the back of the killer who had just run a few steps, and his body was pushed to the ground by the impact of the bullet.

"Over the roof of the dormitory building!"

This shot made the poisonous snake discover Zhang Yu's location.

With the order of the poisonous snake, dozens of guns pointed at the roof of the opposite dormitory building and began to shoot intensively.

"Da da da da da da!"

Hearing the gunshots on the other side, Zhang Yu didn't care at all and continued to use his sniper rifle to find the target.

The range of the assault rifle is not enough, and it is impossible to hit Zhang Yu who is lying on the dormitory building from the other side.

However, Zhang Yu is different. The sniper rifle he used can hit the opponent.

"Bang! Bang!"

With two gunshots, the killer who was shooting at the top of the dormitory building in the warehouse on the other side had an extra blood hole in front of his chest and fell to the ground.

"Stop firing! Keep it away!"
