Han Feng stood in place, his brows furrowed.

"System, analyze the current situation. What is our win rate? Under the difficult decision, Han Feng remembered the system. Maybe in this dilemma, what advice can the system give.

"The system cannot analyze the battle situation for the time being, please wait for the combat laboratory to be completed."

"Alas......" Hearing the system's unique mechanical voice reply, Han Feng sighed. I thought to myself, as I thought, as I thought, without the combat laboratory, it is impossible for the system to answer such questions of its own.

Looking at the battle situation on the first floor of the unfinished building, the last thought was broken. Now, you're on your own!

Closing his eyes, Han Feng's brain began to run rapidly. Any detail that might be missed, or any favorable or unfavorable situation, Han Feng had to take it into account.

The height of the unfinished building is only four floors, and there is no roof and no ceiling......

There are now eleven combatants on their side, with plenty of ammunition and stamina......

The zombies on the periphery have almost been cleaned up, and you can fight with the third-level zombies for a while, waiting for support......

If you leave now, you can wait for the combat laboratory to be built, and protect Wei Peng and Guo Yongxing first...... In just a few seconds, Han Feng thought carefully about the pros and cons.

Suddenly, Han Feng opened his eyes! The final decision was made! Said: "System! Get the sentry gun back! Summons 10 American GIs! Today、Fight! ”

That's right, Han Feng's final decision was to continue fighting! Even if there is no sentinel cannon to support it.

The reasons for Han Feng's decision are: first, whether it is the outside world or the Red Alert soldiers in the unfinished building, the ammunition is very sufficient. Although there are no weapons of mass destruction, there are still many conventional guns and ammunition.

Second, after such a long time of killing, the "little brothers" of the third-level zombies have been killed and injured! If you give up now, the vigilant third-level zombies will definitely gather more low-level zombies by their side in the future! At that time, it will not be so easy to kill a third-level zombie.

Third, you can summon Red Alert soldiers to fight, and they will only fight more and more! On the other hand, the third-level zombie is exhausted! If you don't kill now, when will you wait?!

Fourth, and most crucially! That's the withdrawal this time, and it will be difficult to find the third-level zombie next time!

As for Wei Peng and Guo Yongxing...... Han Feng didn't have a good way now, the combat laboratory had not been built, so he could only wait......

"The Sentinel Cannon has been revoked, and the commander will be returned 5,000 gold. Summoning 10 American GIs costs 5,000 gold, so check it out. ”

"Confirm!" Han Feng said firmly.

"The system is calling, please wait ......"

After the system finished speaking, it began to summon American GIs.

After dealing with everything, Han Feng looked at the first floor again and found that there were many fewer zombies. But what surprised Han Feng was that the zombies on the second floor didn't seem to rush down, just standing quietly on the second floor. It looked like he was waiting for himself to go upstairs.

Seeing this scene, Han Feng smiled contemptuously and said, "Hehe, it seems that you are very afraid of death?!" Zombies are zombies! Even if it evolves, it's stupid! If you all rush down, maybe I won't be so easy. But you let them stand still? Doesn't that make me kill them one by one?! ”

In order to live up to the kindness of the third-level zombies, Han Feng ordered: "Speed up the attack!" Fast! ”

After saying this, Han Feng also raised the assault rifle in his hand and joined the killing team. And the newly summoned American GIs also joined the ranks of the battle one after another.

After several minutes of fierce fighting, the zombies in the first floor have been killed.

Han Feng raised his leg slightly, and a "clanging" sound came from his feet. It turned out that the bullet casings had accumulated a thick layer, and as long as they moved slightly, the bullet casings would scatter and roll off......

At this time, on the first floor of the unfinished building, the strong smell of blood mixed with the pungent smell of gunpowder. Han Feng, who was covering his nose, looked around and confirmed the current "staged" victory.

Looking at the twenty Red Police soldiers beside him, Han Feng slowly led the team towards the stairs leading to the second floor.

Raising his hand, Han Feng pointed to the second floor and said, "High-explosive grenade." ”

As soon as the words fell, the two one-star American GIs quickened their pace, and came to the staircase one step ahead of Han Feng. Pull the tab of the high-explosive grenade and throw it upwards with all your might!

The high-explosive grenade hit the ceiling on the second floor, and the sound of the collision "clanged" crisply. The two one-star American GIs quickly retreated and retreated to a safe area.

"Boom! Rumble!! Two seconds later, two high-explosive grenades exploded. The huge explosion shook the ceiling of the first floor and shook off a huge amount of dust......

"Ahem......" Covering his mouth and nose, Han Feng squinted his eyes and looked at the entrance of the building. There were no zombies rushing down, and there was no counterattack from the third-level zombies.

"Winter Soldier, bring the soldiers up! The four of you prepare a grenade attack! Wayne, you lead the rear support, as long as the zombies are close, attack immediately! All combatants, always keep an eye out for Level 3 zombies! Always be vigilant! ”

The battle has already been fought here. There is no trace of a third-level zombie, is it a conspiracy? Is it timidity? Or is it a plan? The actions of the third-level zombies made Han Feng scratch his head, and he could only cautiously give battle orders.

Watching the seven one-star Red Alert battle elites advance alternately, Han Feng regretted it a little. If Lin Lan was here now, maybe the battle would be much easier. Pity...... But now is not the time to dwell on these issues.

"Boom! Rumble!! ”

When Han Feng was still thinking about his next deployment, the battle at the staircase had already begun!

According to Han Feng's instructions, the four mobilized soldiers, under the leadership of the Winter Soldiers, successfully climbed to the second floor. As soon as they went upstairs, the four mobilized soldiers threw the grenades in their hands in all directions.

After the grenade exploded, before the dust fell, Wayne rushed up with the American GIs and fought side by side with the Winter Soldier and others.

"Dada! Dada! "Fierce firing rang out again.

"Let's go, let's go!" Downstairs, Han Feng rushed to the staircase with ten American GIs.

The first thing Han Feng did after ascending the building was to look around, trying to find traces of the third-level zombies.

Unfortunately, there were many zombies on the second floor, and Han Feng couldn't distinguish them carefully. In particular, there were dense firing sounds and bursting muzzles of fires in his ears, which were undoubtedly factors hindering Han Feng's observation.

Due to the suddenness of the start of the battle, the battle area where Han Feng was located was somewhat narrow, resulting in the American GIs in the rear having no combat position. Under the critical situation, Han Feng ordered: "Move forward!" Expand the battle area! Let more people come up! ”

Receiving an order, the American GIs and conscripts in the front row began to move.

"Whoosh!" Just as the Red Alert soldiers were moving forward, something suddenly changed! The figure of the third-level zombie suddenly rushed out of the zombie group!

The third-level zombies couldn't wait, as the battlefield was encroached upon by Han Feng step by step, there was less and less territory left for the third-level zombies. Taking advantage of the fact that Han Feng still had people on the first floor, the firepower did not reach its peak. The third-level zombie decided to take a gamble......

Since Han Feng was in the protective circle of the Red Alert soldiers, the third-level zombies did not regard Han Feng as the first target, but a mobilized soldier in front of him. When Han Feng saw the third-level zombies rushing out of the zombie group, it was too late to give an order......

In an instant, the mobilized soldier in front of Han Feng was taken captive!

Due to the location, Han Feng could clearly see that the one-star mobilized soldier in mid-air was also desperately attacking the legs of the third-level zombies with AK47.

Pity...... Mobilizers cannot be repositioned to attack the heads of Level 3 zombies. After landing, Han Feng could no longer see the figure of a third-level zombie. And the radar showed that the conscription had just died......

Everything happened so suddenly, and it wasn't until this time that all the American GIs behind Han Feng climbed to the second floor.

Han Feng stood in place, desperately trying to control his emotions. That's a one-star mobilizer! I don't know how many battles it takes to produce a one-star Red Alert soldier!

"Whew...... Breath ......" took a few deep breaths, and Han Feng suppressed the strong hatred in his heart.

"High-explosive grenades! Fry me! Clear!! ”

Han Feng's order was given, and the three American GIs stopped the attack. After pulling the high-explosive grenade from his chest, he pulled the pull tab and quickly threw it into the crowd of zombies in the distance.

"Woo~Woo~!!" As soon as the high-explosive grenade was released, the weird whining of the third-level zombie rang out for a long time.

The strange noise this time was different from the previous sounds, as if it was aimed at Han Feng and the others, because the zombie group did not riot because of the strange noise.

"Ah......" The pain in his head was unbearable, and Han Feng insisted on shooting with one hand and covering his ear with the other hand. But it didn't work...... The sound seemed to be able to penetrate all obstacles and pierce straight into Han Feng's weak brain.

Not only Han Feng, but also mobilized soldiers and American GIs have all been recruited! They all fell to their knees and fired with difficulty. It was also thanks to the fact that Han Feng summoned all well-trained Red Police soldiers, otherwise ordinary people would really not be able to stand it in this environment.

"Boom! Boom!! "At this time, the previous three high-explosive grenades exploded! The explosion of the high-explosive grenade interrupted the whining of the third-level zombie, and Han Feng was temporarily saved.

"Luna, what's that sound? Why is this happening? Standing up from the ground, the first thing Han Feng did was to figure out what was going on with this voice.

"I'm sorry for Team Korea...... The system cannot be analyzed at this time. However, according to the preliminary detection of the system, it should be some kind of sonic attack, or a means similar to sonic attack. More specifically, the South Korean team is requested to wait for the completion of the combat laboratory before conducting research. ”

Han Feng listened to Luna's report while trying his best to find the figure of the third-level zombie. Finally, the sky pays off! The third-level zombies really let Han Feng see it!

"Sonic attack?" Han Feng responded to Luna while staring at the third-level zombies.

"Not so sure, because the system can't do deeper research." Luna replied to Han Feng in an apologetic tone.
