Qiao Yuchen's consciousness moved, and the exchange machine appeared, he did not hesitate at all, and clicked directly on the patrol dog.

Yes, what he has to do is to exchange a large number of patrol dogs, with the strength of the fourth level of patrol dogs, there is a certain number, and they will be able to crush it.

"Drop, it takes 10,000 energy points to exchange for patrol dogs, please confirm whether to exchange them..."

"Redeem"

"Drop, the exchange is successful, please check it by yourself..."

Qiao Yuchen didn't dare to stop for a moment, didn't look carefully, and directly summoned the patrol dog from the space, which was also a black back.

At this time, Qiao Yuchen didn't have time to think about naming the patrol dog, and said directly, "Wang Da, go and help the war." ”

As soon as this black back came out of the system space, before he had time to be curious about the surrounding situation, he was pressed by the owner with the name "Wang Da".

Wang Da suddenly felt that the whole dog life had become bad, so forget it, before it had time to breathe out the first breath of air, it was directly ordered by this unscrupulous master to help in the war.

What the hell is this, fight your sister, you didn't even see the surrounding environment clearly, so let the dog help fight, is this really good?

Wang Da was slightly stunned, and then quickly rushed towards the zombie group, fighting was its instinct.

The four people who were paying attention to Qiao Yuchen while collecting crystals saw Qiao Yuchen suddenly make a patrol dog, and the movements in his hands slowed down a little.

When they heard Qiao Yuchen call Wang Da again, the four of them almost couldn't hold back their laughter, and then saw Wang Da's confused dog face expression. Suddenly, the four of them were thrown out even the tension on the battlefield. Being able to hold back not laughing out loud is already very powerful.

Where did Qiao Yuchen notice this, summoned "Wang Da", he didn't let himself rest, and quickly rushed behind Nangong Yixiao and a few people, and the five-four system in his hand shot at the zombie group again.

With the fourth-level strength of Wang Da to help the battle, the pressure on Nangong Yixiao and the five people was greatly reduced, but even so, they still did not dare to take it lightly. As a lesson from the past, they will never make such a fatal mistake again.

Looking at the three-headed patrol dogs rushing back and forth in the zombie group, Qiao Yuchen's confidence increased greatly, but he also didn't dare to relax, the faster he scored, the more chance Uncle Jin and them had to live.

Time is passing rapidly, even if Qiao Yuchen and the others, while trying their best to kill zombies, they are still moving forward, and the speed is still very slow.

In the community on the shore, there are already zombies rushing in, and Uncle Jin and others are protecting the sisters and brothers and struggling to kill the zombies.

Xu Long climbed far away to a small building, standing at the window on the third floor, the G3 sniper rifle in his hand kept shooting bullets. Resolve the crisis for Uncle Jin and them, and at the same time snipe the zombies who came in over the wall.

That's when the walkie-talkie rang.

"Uncle Jin, lock yourselves up with an alloy wall, and wait for me to ......"

It was Qiao Yuchen's voice, when he was using the alloy wall to assist him in moving forward, he suddenly thought of this problem, Uncle Jin They have an alloy wall there, they can completely protect themselves, so that at least they can hold out until they rush over.

Hearing Qiao Yuchen's words, Xu Long looked into the distance with a G3 sniper rifle, and it was too far away from them that Xu Long didn't see anything.

Below, Uncle Jin and Da Meng have retreated to the three-story building where Xu Long is.

"Uncle Jin, we can't let Yuchen and them bear so much pressure, we don't attract zombies here, then Yuchen ......" Xu Hua was very worried about Qiao Yuchen. She was afraid that Qiao Yuchen would have an accident in order to save them.

Uncle Jin also understood what Xu Hua meant, and he didn't have anything to do for a while, but he still let Da Meng install the alloy wall.

It's just that they built a labyrinth of the remaining alloy walls in the community. And Xiaolong is upstairs watching the situation in the entire labyrinth and reporting it at any time.

Uncle Jin and they sniped zombies in the maze, and this method also played a very good role for a while, although there were many zombies coming in, but because of the maze, they were all scattered.

With Xiaolong's guidance, Uncle Jin and the others calmly ate wave after wave of zombies.

Their situation is barely stable.

In the distance, Qiao Yuchen had already advanced half a block with nine members of the Blood Ten Guards. It's a tough half of the block. It wasn't until a community that they held it firmly.

Qiao Yuchen looked around carefully, and it was still about three blocks away from the community where the sisters and brothers were.

There are too few alloy walls, and Qiao Yuchen can only strengthen part of the place, so he still leaves an opening at the entrance of the community, so he lets the zombies in and snipe.

And the zombie crystals collected before have been collected by Qiao Yuchen.

"System, how many energy points are there?"

When he started exchanging, Qiao Yuchen also had some consciousness to pay attention to how many energy points he had, but the further he advanced, the more dense the siege of zombies became, and Qiao Yuchen didn't have time to check the energy points at all.

Just a little bit of consciousness to answer the system and confirm the exchange.

"Drop, 54213 points of remaining energy..."

"Poof... It's really two, this number is too painful, 54213...isn't this (I'm 2B)......."

Qiao Yuchen was speechless, not knowing how such a number could appear.

"I said system, you mean it, how can there be a singular number of 13? Shouldn't the redemptions all be whole numbers? ”

"Drop, there is a part of the pseudo-secondary energy and pseudo-tertiary energy in the collected energy..."

"Uh... Even so, can't you give a whole number? Is it necessary to be so stingy? ”

"Drop, every bit of energy needs to be collected by the host itself, and the system can't give it..."

"Hehe, pull it down, don't talk nonsense with you."

Qiao Yuchen didn't have time to argue with the system, so he quickly called up the exchange machine.

The exchange of patrol dogs just made him a little depressed. When Qiao Yuchen exchanged for the last patrol dog, the system gave a prompt tone again.

"Drop, the patrol dog has the remaining number of redemptions (once)..."

"What? What the heck? system, what kind of wind are you pumping? Qiao Yuchen asked the system in surprise.

"Drop, the host's current level can only be exchanged for ten patrol dogs..."

"Damn, system, you're killing me.... How can I increase the number of redemptions? Qiao Yuchen was a little anxious.

Five patrol dogs have been added, although he can also be crushed, but he has no sense of security, who knows if zombies will suddenly appear a large number of fourth-level or even fifth-level zombies.

"Drop, the host cannot be upgraded at the moment, please complete the main quest as soon as possible......"

"Ahh

Qiao Yuchen had the urge to scold his mother, and accidentally scolded out of his mouth. The four Li He, who were moving the crystal over, looked at him strangely.

Qiao Yuchen also noticed that Li He was looking at him, and he didn't care about explaining anything, and as soon as his consciousness moved, patrol dogs appeared around him one by one.

There are five patrol dogs, which look very majestic, Qiao Yuchen pointed over one by one, "Wang Er", "Wang San", "Wang Four", "Wang Five", "Wang Six".

"Come on, Wangwang...."

"......" Wang Er to Wang Liu's bewildered dog expressions.

"......" Li He and the four of them also had a confused expression, and they couldn't help but slander in their hearts.

"Boss, is this playing Pokemon? Come on, Bikachu??? ”

"......" system.

Thanks to the system, he is not a real person, otherwise he doesn't know what to complain about Qiao Yuchen.

Wang Er to Wang Liu reluctantly rushed towards Wangcai, Da Wang, Er Wang and Wang Da. Wang Da looked at his brothers with a playful expression. That's a lot of sympathy.

Wangcai slapped the zombie in front of him, but the dog's mouth grinned, as if he was laughing at his juniors, at least his Wangcai's name was much better than them.

Fortunately, Qiao Yuchen didn't see the expressions of these dogs, otherwise he would have thought that these dogs were all sperm.

With a new force joining, Qiao Yuchen and the others once again pressed towards Uncle Jin and their community.

Nine fourth-level patrol dogs, these first-level zombies, second-level zombies, and even third-level zombies in front of them have all been reduced to scum.

Even Nangong Yixiao's five people have become workers collecting zombie crystals.

Qiao Yuchen's mood finally improved, and he seemed to see countless energy points flying towards him again.

"To rescue them this time, we must make everyone wake up......"
