Shen Yan was safe there, and Li Tianyu was relieved. Now he can deal with the tide of corpses without any worries. Of course, with his remaining domineering power, it is impossible to clean up the tide of corpses. With Zheng Nanxing's help, it shouldn't be difficult to do.

Small zombies and specially infected persons move in different ways. Small zombies will rush up from the emergency escape route of the hospital, while specially infected persons will climb up the wall, which causes the specially infected persons to come up before the small zombies.

"Brother Tianyu, I will help you guide the lightning, you just throw it away." Zheng Nanxing replied.

Li Tianyu nodded, then raised his right hand to the sky and released Wan Lei. Zheng Nanxing waved his arm like an elegant orchestra conductor. The thunder and lightning falling in the sky not only increased, but also adjusted the flight direction and landed on the periphery of the special infection. On the body, they shot them down. And Li Tianyu took advantage of this effort to start Lei Ying's energy accumulation.

The small zombies outside couldn't rush into the hospital because there were too many, so they gathered around the hospital in large numbers at the moment, crowding in groups. And what Li Tianyu was waiting for was now. He threw Lei Ying to the ground. The thunder and lightning quickly spread and swallowed all the zombies at the entrance of the hospital. Then Li Tianyu frantically used God's punishment to bombard the opposite side.

But in fact, Lei Ying after Zheng Nanxing's increase was enough to clean up these little zombies.

However, at this moment the second tyrant has landed on the roof. The tyrant’s huge size and cold expression frightened the survivors on the roof to scream. Li Tianyu threw a thunder dragon on the tyrant and blasted it down, but the other tyrant pounced from behind to survive. By. Fortunately, Zheng Nanxing took the shot at this time.

The tyrant's paw seemed to hit an invisible wall, and he was bounced abruptly and took a step back. Then Zheng Nanxing raised his hands and pushed out forcefully, and the tyrant fell off the roof.

Their task is not to kill the zombies, but to ensure safety on the rooftop.

At this moment, the sound of helicopter propellers also began to come from afar, Li Tianyu turned his head to look, two helicopters had already appeared in his field of vision. However, the helicopter brought not only rescue, but also a large number of zombies.

Li Tianyu's heart network could perceive that all the surrounding zombies followed the helicopter towards the hospital, but he did not panic, leading the survivors to the tarmac on the top of the hospital to wait for the helicopter to land.

At this time, there was a banging sound from the door of the rooftop, and then a large number of zombies slammed open the door and rushed up.

Suddenly, the rooftop seemed to be surrounded by zombies in all directions. The survivors shivered behind Li Tianyu, but Li Tianyu remained unmoved and threw a new lightning star from the center area. The spreading lightning immediately knocked all the zombies into flight, and at the same time blocked the way of the zombies coming up behind.

At present, because there are too many zombies, the zombies crowded in front and blocked the back cannot approach.

It is precisely because of this that those tyrants and specially infected people are blocked by the little zombies and cannot approach them, so naturally they cannot cause trouble to them. Li Tianyu didn't kill these zombies, but just used the knock-to-fly skills to repel the zombies from the top of the building to prevent the enemy from approaching. Anyway, the ability of the Thunder Fruit is not consumed, and he can continue like this forever.

Coupled with Zheng Nanxing's help, it is relatively easy to maintain the current situation. Although zombies rush to the top floor from time to time, there is no way to get close to the survivors. At this time, the helicopter finally approached the roof of the hospital.

And just as the helicopter approached the tarmac, a neat scream came from all directions, and the zombies in the entire city fell into a violent state. A dozen tyrants rushed out of the corpse wave and quickly climbed up the wall.

Li Tianyu knew that this was the last wave, so he turned on the Enhanced Thunder Armor, and the thunder and lightning that surrounded him was dyed black. Li Tianyu raised his hand to condense Lei Ying, and then threw two thunder guns out.

Two tyrants were shot down from mid-air, but the other eight tyrants had landed on the balcony and pounced on the survivors. Zheng Nanxing’s protective cover blocked them, but the tyrants seemed to be crazy, and they caught Zheng Nanxing’s protective cover frantically. The sound of "ping-pong-pong" came and Zheng Nanxing's expression changed. It was a little bit painful.

"Brother Tianyu, I'm almost running out of calculation power!" Zheng Nanxing asked him for help. Li Tianyu threw the condensed Lei Ying to Zheng Nanxing, because Zheng Nanxing has a memory of his lightning and can automatically filter his lightning, so as to protect her and those survivors from being injured by Li Tianyu's lightning. , But those tyrants are different.

"Hurry up and get on the helicopter!" Li Tianyu instructed the survivors behind Zheng Nanxing, and then another enhanced chain lightning was thrown out. The black thunder and lightning bounced back and forth on the eight tyrants, accumulating two layers of passivity.

At this time, Li Tianyu was not in a hurry to trigger his passivity. His task is to delay time, not to kill these tyrants. Therefore, he just swept away with a flash of thunder, knocking away the specially infected people and the little zombies that had climbed up from the edge of the roof.

But soon, the first tyrant resumed his actions and raised his hand to continue his attack. Li Tianyu snapped his fingers, and the electric spark triggered his passive detonation. Then Li Tianyu flashed close and punched the tyrant in the chest. , With the blessing of armed domineering, this punch knocked the tyrant flying out and hit the building next door.

Although the damage of Chaos Thunder is high, the impact is very small. It is difficult to cause a strong impact on a large enemy like a tyrant, but the physical attack is just the opposite. Although it cannot cause strong damage, it can The tyrant flew far away. After knocking the tyrant into the air, Li Tianyu did the same and kicked the other two tyrants away from the top of the building.

At this moment, eight survivors have boarded the helicopter. It's just that the survivors who stay here have inconvenient legs and feet, so the transfer speed is quite slow. Just when Li Tianyu was about to turn his head and continue to deal with the zombies, something happened suddenly, and the ceiling under their feet suddenly shattered, and a python-like tongue came out from below, entangled and dragged a survivor down.

"Really, this is the fat man who is specially infected... This thing would not actively attack before." Li Tianyu couldn't help being surprised. Now all the zombies are targeting the survivors, which is very troublesome. Especially when a hole was made in the low board this time, the zombie broke through Zheng Nanxing's defense line and began to approach the survivors.

But now Li Tianyu and Zheng Nanxing are almost exhausted, so there is only one choice. Li Tianyu flashed to the little nurse and several patients, and then flashed into the helicopter cabin again. Then he flashed out, flashing back again with the two survivors.

In such a narrow place in the helicopter cabin, there is no way to bring a large number of survivors in at one time, otherwise it may cause a space collision. Li Tianyu is not clear about the result. It is very likely that the survivors will get stuck inside the helicopter. As a result, the helicopter was also damaged, so only two or three came at a time.

The little nurse was saved anyway. After all, the little nurse had been in the hospital for so long to take care of the survivors and assist them in their management. Even if it was just an NPC, Li Tianyu, she would have to save her.

But at this moment Li Tianyu and Zheng Nanxing were both transferring the survivors to the helicopter, which naturally caused the zombies to swarm up, drowning the two survivors with inconvenient legs and feet in the blink of an eye, and a heart-piercing scream came.

"There's no way, let's do it!" Li Tianyu gritted his teeth while watching the zombies coming up like a tide. The black thunder and lightning on his body dispersed and returned to blue, and his last trace of domineering was used up, so he turned to the driver: "take off!"

"But, there are..." The little nurse looked at the six or seven survivors under the helicopter a little bit unbearably. However, there were too many corpses. Li Tianyu had not cleaned up before, but just shot the zombies into the air and prevented them from climbing. , So now those accumulated zombies will naturally submerge the entire rooftop, and tyrants and other special infected persons have also emerged one after another.

If you delay any longer, the two helicopters will also be affected. The pilot knows this very well, so he operates the helicopter to take off. However, the helicopter shook violently as soon as it took off. Li Tianyu opened the door of the helicopter and took a look. A tyrant hung on the tripod of the helicopter and did not let go. At that time, he thunder dragon screamed on its face: "Quickly roll!"

The tyrant let out a dull roar, fell from the helicopter, fell in the middle of the tide of corpses below, and disappeared in an instant. The helicopter stabilized again and began to fly outwards slowly.

"It's really terrible, this mission..." Li Tianyu sighed with a long sigh of relief, leaning on the cabin.

At this moment, he was already quite tired, and the domineering that finally recovered was emptied again because of the strengthening of Thunder Armor.

Fortunately, the mission is completely over here, and then just go outside the city with the helicopter to meet Shen Yan. He counted. There were eight people on this helicopter, including Zheng Nanxing and the little nurse, and ten people on the other helicopter, a total of eighteen survivors. Twelve were lost in the final evacuation. Survivors.

In the end, the rage of the corpse tide was still too difficult to bear. Li Tianyu reviewed the various details of the mission and found that there were still some details that had not been handled properly, otherwise the mission should be relatively simple. The main reason is that many areas have not had time to explore. The main reason for this is that the number of survivors in their hospitals is too small.

In fact, Li Tianyu also knows very well that as long as the rationing of supplies can be reduced and everyone's diet can be kept to a minimum, they can feed 80 to 100 survivors. Although it will be more difficult, they will explore after more people. The area is bigger.

After the area explored increases, more side missions will appear, and more camps for other survivors will be discovered, just like the restaurant in the sky before. The side missions will bring them additional benefits, and there will be some NPCs with special abilities in other survivor camps to help them survive better.

As for why he didn't have that choice... Li Tianyu guessed that he was probably unwilling to take that risk.

Everyone has different personalities. If there is a 100% chance that you can win fifty yuan, and a 50% chance you can win one hundred yuan, but you may not be able to win one dollar, then Li Tianyu will definitely choose to win fifty yuan.

Of course, even if there is a 100% chance that you can win fifty yuan, and a 5% chance you can win one million yuan, you may not win one dollar. Li Tianyu will choose to win the fifty yuan. He is not the type who likes to get rich overnight. Instead of returning empty-handed, he would rather come back with fifty dollars.

"Huh..." Li Tianyu closed his eyes, tiredness swept over him, his tense nerves relaxed and made him extremely tired. Zheng Nanxing hugged his head and smiled: "Brother Tianyu, shall I be a knee pillow for you?"

"I..." Li Tianyu actually wanted to refuse, but he was too tired at the moment. Zheng Nanxing pulled it lightly, and he fell on the little girl's lap. Compared with Shen Yan's elastic legs, the little girl's legs are as soft as boneless. Li Tianyu's heart is rebelling, but his body is honestly compromising.

The helicopter moved forward slowly, shaking, and it didn't take long for Li Tianyu to fall asleep.

The violent shaking that caused him to wake up seemed to be that the helicopter had finally landed. The hatch of the helicopter was opened, and Shen Yan greeted him happily. When she saw the situation in front of him, her face suddenly sank, but when she saw the tired expression on Li Tianyu's face, she softened again and stepped forward. Support Li Tianyu to help him stand up.

After sleeping for about half an hour, Li Tianyu also regained some energy. He held Shen Yan's shoulders to stabilize himself, and asked: "How many survivors on your side have survived? We only have ten. Eight people…"

"Twelve people survived on our side. When we approached the edge of the city to break through, many foreign troops came to obstruct them. They didn't want us to go out of this city for fear that we could spread the virus. We had to go around. It's a long way, most of the survivors were shot dead at that time." Shen Yan explained.

"In the end, only thirty people survived?" Li Tianyu said helplessly, "Well, thirty people is thirty people."
