It was just a pile of scrap iron, but what Zhang Kaiyuan regretted at this time was that he didn't use these scrap irons in place.

It's just that the tank fired two shots at the two fifth-level zombies when he rescued the field regiment before, and blew up the two fifth-level zombies, which made Zhang Kaiyuan already a little dizzy.

He actually thought that these things could also be invincible in the world, a kind of small peasant thought was deeply ingrained in his thoughts, once this kind of thinking spread, Zhang Kaiyuan couldn't hold back his stinginess, under this kind of stinginess, he ate the bitter fruit at the moment.

The more Zhang Kaiyuan thought of this, the more depressed and manic his heart became, the last thing he said just now was that all the staff retreated, shooting alternately to retreat, and he was responsible for covering the slopes on both sides.

To be exact, he can only cover one side, and he can't cover the slope of the other side, just because Zhang Kaiyuan has only one person, and this entire canyon is about 10 meters wide.

In the 10-meter-wide valley mouth, Zhang Kaiyuan really couldn't do it left and right, he supported the right and left, he couldn't take care of it, just when the team retreated, those fifth-level zombies were indeed stopped by the modified smoothbore cannon.

Zhang Kaiyuan had already skimmed this situation in the afterglow, and the stone in his heart could be regarded as a little bit of a drop, after all, the pace of those weapons on the market was linked to the retreat speed of the entire team.

When the footsteps of the fifth-level zombies stopped, the speed of the team's retreat was faster, and after the safe retreat, Zhang Kaiyuan also reduced some sins in his heart.

However, the zombies on the right, the second-level zombies and the fourth-level zombies' charging field, if they can't be stopped, then they will also usher in a catastrophe, because even in his team of special combat personnel, no one can easily fight against the second-level zombies.

What's more, there are more fourth-level zombies there, when the fourth-level zombies appear, that kind of is an alternative slaughter, and the speed of the fourth-level zombies is very fast, in the crowd, it is like a harvester with a human head.

So Zhang Kaiyuan asked Shen Kuo not to skimp on the shells of the smoothbore cannon, and one of the directions of the muzzle was to point directly at the group of zombies rushing down.

\"Ahh \"

Zhang Kaiyuan saw that Shen Kuo had already started to fight with the zombies on the left, and he also rushed into the zombie group on the right, and the Tang knife in his hand was instantly unsheathed, and he slashed at a second-level zombie who rushed over.

The body of the second-level zombie rushing forward was still in the air, and a black blood stain shot out of his waist, and at the moment when the black blood mist sprayed, the legs of the second-level zombie were still running in front, but the upper body had lost the momentum of impact.

Zhang Kaiyuan didn't stop, he still kept charging forward, and instantly rushed past the second-level zombie who was cut by him, he didn't look at it, and directly continued to wave the Tang knife in his hand, and the sound of the green knife waved Zhang Kaiyuan as if it were above.

I saw that after his long knife was swung, a cold light would be left in front of him, and with the flash of cold light, there were constantly second-level zombies falling, and when the sixth second-level zombie fell, the fourth-level zombie finally couldn't help it.

At the moment when the driver zombie launched a charge, he could see an afterimage rushing towards Zhang Kaiyuan.

At the moment when the afterimage rushed over, Zhang Kaiyuan had already made preparations, only to see his long knife behind his back, holding the scabbard in one hand, charging in the other direction, there was a boulder in front of them, Zhang Kaiyuan stepped on it directly without thinking about it.

When Zhang Kaiyuan stepped on the boulder, the zombies behind him had already chased over, Zhang Kaiyuan jumped up suddenly, and stepped on the stone with the boulder, he jumped at least 4 meters away, with this height, the zombies behind him had already arrived, only to hear a sound like metal hitting behind him, Zhang Kaiyuan looked down, the boulder under his feet had been scratched by the zombies like sparks.

At the same time, he saw a few sparkling claws, following behind him, Zhang Kaiyuan jumped high, and then turned around and threw out the long knife in his hand.

Tang Dao slashed a cold light under his feet, and after the cold light flashed, the zombie's claws also stopped behind him, and began to fall downward.

Look at the two fourth-level zombies on the hillside at the beginning of the day, they have been lying there silently, to be precise, these two fourth-level zombies, only their bodies are lying under the hillside, and the heads of the two zombies are like two footballs, rolling down continuously.

And the fall of these two zombies did not attract the attention of the other second-level zombies, the other second-level and fourth-level zombies, as if they were ignoring, at this time Zhang Kaiyuan suddenly felt a chill behind him, and then he turned around and looked back.

I saw a second-level zombie and a fourth-level zombie who had jumped down from behind him, and the two zombies bared their teeth and stretched out their strength at the same time, and the direction they grasped was obviously the back of Zhang Kaiyuan's heart.

However, Zhang Kaiyuan didn't think twice, at this time his impact power had been exhausted, and his body had fallen downward, but the two zombies on the opposite side had indeed just begun to charge, if he fell at this time, he would definitely be hit in the air by these two zombies.

However, there were also two zombies rushing over below, and if he was surrounded by four zombies at the same time, it was difficult for Zhang Kaiyuan to retreat with his whole body, well, thinking of this, he just opened the source without thinking, and put his hand into his arms, only to see him groping for a while, and an oval-shaped black grenade appeared in his hand.

Zhang Kaiyuan opened the grenade safety in his hand, and then jumped with the take-off of the safety spring on the grenade, and then the oval grenade flew towards the zombies behind him, and he opened his eyes to stare at the two zombies who wanted him to be more angry.

\"Ahh \"

Zhang Kaiyuan roared angrily, and slashed at the two captured zombies, completely ignoring the sharp claws that the two zombies had already grabbed at his chest.

At this time, there was a huge explosion behind him, Zhang Kaiyuan felt a pain in his chest, and he didn't have time to check, and at the same time as the cold light flashed, the two figures rolled down the hill with him.

Zhang Kaiyuan had already thrown out the long knife in his hand, he was vague, just glanced at it, and at that moment of inspiration, Zhang Kaiyuan threw his long knife to the position of the hillside at his feet.

The roar after the explosion behind him let Zhang Kaiyuan know that the gravel on the boulder behind him must have been blown down by the grenade before him, which means that he doesn't know how many broken stones are behind him now, and he doesn't know the size of these stones.
