Chapter 823 One and a half hours

However, Zhang Yu has no time to observe whether Li Erniu is safe or not.

His own situation is very dangerous.

Hearing the sound of the exercise grenade breaking through the air, Zhang Yu's reaction was also very fast and he hid directly into the sewer.

Fortunately, this was just an exercise grenade, and there were no shrapnel splashes after the explosion.

Otherwise, the splashing shrapnel generated by the grenade explosion will enter the sewer along the drainage ditch, and the unlucky person will be Zhang Yu.

After squatting in the sewer for two minutes, Zhang Yu heard that the bombardment above had stopped.

Depending on the situation, they should have wiped out all the exercise grenades in their hands.

Zhang Yu was considering whether he should return to his position immediately to prepare.

"Zhang Yu, they have stopped bombarding and are on guard.

Do you want to go back to the pre-determined position for alert?”

Just then, Li Erniu's voice came from Zhang Yu's headset.

It turned out that when Zhang Yu reminded Li Erniu to avoid it, Li Erniu had already jumped from the power control room to the office next to hide.

There is a window with glass removed between the power control room and the office. Li Erniu just jumped from the empty window to the office.

Compared with Li Erniu's position, Zhang Yu's current position cannot better observe the above situation.

Hearing Li Erniu’s reward, Zhang Yu thought for a while, and a storm blew in his mind.

No, the five men fired only twenty grenades in seven minutes, not to mention that they were not intensive bombardment. How could they finish the exercise grenades so quickly?

Could it be that this is a strategy?

The defensive special forces deliberately stopped the attack, making Zhang Yu and the others think that the grenades in the hands of the defensive special forces had been exhausted, forcing Zhang Yu and Li Erniu to return to their combat positions.

As long as Zhang Yu and Li Erniu return to their combat positions, a new round of attacks will come.

Yes, that's it, what a ruthless plan.

"Don't worry, Erniu, they still have grenades in their hands.

Keep staying in the office and waiting for my order.”

Zhang Yu, hiding in the sewer, could hear the subtle footsteps above his head. The walls on the sewer were not very thick, and Zhang Yu's hearing was much better than that of ordinary people.

Therefore, as long as the mosquito humming sound is not made from above, Zhang Yu can hear the sound.

As long as the defensive special forces launch an attack, Zhang Yu, who is hiding in the sewer, will definitely hear their footsteps.

It would not be too late for me and Li Erniu to return to the combat position, and it would not delay the fighter plane.

On the other side, the special forces of the defensive side squatting near the gate saw that Zhang Yu and Li Erniu did not come out after the attack was over and did not continue to launch the attack.

Unexpectedly, Zhang Yu and the others actually saw through their plans, and the current situation is very embarrassing.

Zhang Yu and Li Erniu are very hidden, and they are easy to defend and difficult to attack.

The known location of the defensive special forces is the only power control room where Li Erniu is located.

But there is only one staircase on the second floor on the workshop, and the firepower from the second floor can completely cover the staircase.

Coupled with the influence of the height difference, people on the first floor could not hit the power control room at all. For a moment, the special forces of the defensive side did not know how they should deal with the current situation.

Should I retreat temporarily or continue to attack?

Taking this opportunity, Zhang Yu noticed that he had squatted in the drainage ditch in front of the second floor stairs, and did not expose his position.

Most of the area on the first floor is under the firepower range of the grenades. Any small moves of Zhang Yu will be covered by the sudden arrival of firepower.

Therefore, Zhang Yu could only choose a farther and hidden location to continue waiting.

The drainage ditch under the second floor is a good place. Zhang Yu can not only continue to shoot the advancing defensive special forces in the drainage ditch, but also retreat to the second floor along the stairs at critical moments and cooperate with Li Erniu for defense.

Half an hour has passed.

After taking a look at his watch, Zhang Yu changed the magazine for the assault rifle.

There is still one and a half hours, and the matter will be over after another one and a half hours.

"You four are on the second floor. As long as the second floor dares to show their heads, they will attack them with grenades.

The rest of the people were on guard with me, and they were moving forward carefully and searched carefully."

While Zhang Yu changed his position, the defensive special forces have also made offensive deployments.

Seven men formed an attack formation and carefully searched forward.

The obstacles left by Zhang Yu on the first floor caused great trouble to the advance defending General Fante.

They were afraid that Zhang Yu would not know what to hide behind and suddenly attack him, so the special forces on the defensive side were very careful to advance. They had to check every obstacle and make sure there was no problem before they would move forward.

"Zhang Yu, they have advanced to the nearest of the first drainage ditch."

Hearing the observation of Li Erniu in the headset, Zhang Yu got up from the ground and squatted in place, contacting Li Erniu.

"Don't move for now, they know your position and they will definitely focus on you.

Wait until their attention is attracted by me and you will attack."

"receive."

After contacting Li Erniu, Zhang Yu lowered his body and walked into the sewer silently.

Going near the first drainage ditch?

Interestingly, I'll wait for you in the sewer.

Seeing the first drainage ditch, the defensive special forces, who had not been eliminated before, raised their hands to signal the team to stop moving forward, and whispered to their companions.

"There was someone who ambushed us here before."

It seems that this defensive special forces still care about Zhang Yu's previous attack on them in the drainage ditch.

"knew."

There is no problem in the drainage ditch now, and the defensive special forces plan to give up this place and continue to move forward.

However, the leader thought again and said, it would not be good to give up like this. What if Zhang Yu suddenly appeared from below and attacked him behind him?

"You go down and see what's going on inside."

"clear."

A defensive special forces jumped into the drainage ditch, held his gun and lowered his body and walked slowly towards the sewer.

The others formed an attack formation and continued to move towards the second level.

The sewer was too dark. The defensive special forces who entered the sewer were about to take out the flashlight to make it easier for them to observe the situation, but a hand suddenly stretched out from behind him and covered his mouth.

It's Zhang Yu.

When Zhang Yu covered General Fangte's mouth, the marker in his right hand wiped a marker around the neck of the special forces defending.

After eliminating the defensive special forces, Zhang Yu took his hand away from his mouth.

Everyone knows the rules of the exercise in their hearts. If they are eliminated, they will be dead and cannot interfere with the exercise.

"There is no problem below, I will talk to you right away."
