There was still silence in the intercom, and Qiao Yuchen's heart seemed to have fallen into an endless abyss.

"Whew... Multiply... Yuchen ......"

Hearing a familiar voice coming from the intercom, Qiao Yuchen couldn't hide the excited expression on his face, hurriedly grabbed the intercom, and asked eagerly, "How are you doing?" Is there something wrong? ”

There was a brief silence in the intercom again, and then Xu Hua's voice came: "Chen... Hide back at base and leave us alone... There are too many zombies, and Xiao Jiu has ...... Zombies are piling up crawling over the alloy walls, and we won't be able to hold out for long......"

"Shut up ....."

Qiao Yuchen heard Xu Hua say about their situation, and his anger suddenly rose.

"You damn woman, you can't just leave me like this, you hold on, you must hold on, wait for me to kill you. I will save you, and I will ......"

Qiao Yuchen's eyes were already full of tears, and the blood ten guards and nine people had never seen such a gaffe boss.

There was silence on the other side of the intercom.

Qiao Yuchen's head was running extremely fast, and his mouth had already begun to give orders: "Da Wang, Er Wang, attack the zombies, let's kill them." Blood Ten Guards, keep up. Today we are going to fight a bloody battle. ”

Holding the alloy knife in his hand, Qiao Yuchen and the Blood Ten Guards followed closely behind Da Wang, and Er Wang rushed towards the hordes of zombies.

There are a lot of zombies, but there are also many low-level zombies, Qiao Yuchen didn't stop cutting zombies in his hands, and he was asking the system in his head.

"System, is there any super ability to help?"

"Drop, the temporary power system can only be used when the host is dying, and the host is reminded that the ability of the temporary power system cannot destroy all zombies..."

Qiao Yuchen's heart was a little lower, originally the system said that he would use it when he was dying, and he wanted to risk death to trigger it, but the system immediately dispelled his idea.

"System, is there no other help that can help? Human life, if you don't help, these people will all die..."

Qiao Yuchen yelled anxiously at the system. Although it is conscious, the emotions are well preserved. It seems that he felt Qiao Yuchen's anger, or maybe the system didn't want the power established by the host to say goodbye directly, and the system still helped Qiao Yuchen.

"Drop, prompt the host, make reasonable use of the exchange system..."

"Exchange system, exchange system..... yes, I still have this. ”

The system's prompt made Qiao Yuchen think of a brilliant idea. As soon as his consciousness moved, Qiao Yuchen saw the box lying in the system space.

"System, exchange energy points for me."

"Drop, the host has two third-level energy, which can be exchanged for 1,000 energy points, and one fourth-level energy, which can be exchanged for 5,000 energy points, please confirm whether to exchange it..."

Qiao Yuchen said without hesitation: "Confirm." ”

"Drop, the redemption is successful. 6350 energy points remaining..."

Looking at such a small number of energy points, Qiao Yuchen sighed in his heart, but now he can't afford to think too much.

"Da Wang, Er Wang, don't rush too forward, go around us to kill zombies, Li He, Qiao Mu, Yuchun, Meng Hai, the four of you collect zombie crystals."

"Smile, the wind is not rising, Han Yong, Wu Cun, Wu Yi, the five of you spread out and protect Li He and the four of them to collect crystals."

Qiao Yuchen kept in his hands, and ordered in his mouth.

Although the Blood Ten Guards and Nine People wondered why Qiao Yuchen had let them scatter their combat power to collect crystals at this time, they were not allowed to ask anything at this moment. They could only quickly carry out Qiao Yuchen's orders.

Nangong smiled and the five people quickly dispersed, attacking the zombies rushing around, the first-level zombies around accounted for the majority, they had the alloy knife given by Qiao Yuchen, and there was no problem at all in dealing with the second-level zombies.

Reasonable cooperation, coupled with the wandering of Da Wang and Er Wang, although the speed of progress is not fast, there are many zombies killed.

Qiao Yuchen also stood within the range of the five people, his consciousness moved, and there were three more bottles of physical strength potion in his hand.

"Li He, take the potion, let him take a sip if he is exhausted." Qiao Yuchen handed out three bottles of physical strength elixir, so that everyone could maintain enough combat power.

Li He took the potion, stuffed it in his pocket, and quickly collected crystals from his underground body, the speed at which the four of them collected crystals was very fast, and the perennial life in the last days made them know too much about the structure of the zombie brain, and they could accurately find the location of the zombie crystals with every knife.

Qiao Yuchen took out the five-four system, the only gun in his hand, and the ammunition was also sufficient, his consciousness moved again, and a box containing supplies appeared, and there were a lot of empty boxes in his space. It was meant to prevent things from being loaded.

"The crystals are all thrown into the box."

After speaking, Qiao Yuchen did not stop.

"Bang bang..."

Two alloy walls appeared behind everyone, and the Blood Ten Guards were fighting, and they didn't have time to pay attention to the alloy walls that suddenly appeared.

The wall was thrown out, and a ten-meter-long barrier stretched out from behind, Qiao Yuchen didn't stop, and ran to the right.

"Bang bang..."

Two more alloy walls, again a ten-meter-long block, the interface connected to the wall behind it, and then the same two-meter wall was dropped to the left.

In an instant, the crowd was surrounded by three walls.

"Da Wang, Er Wang, shrink back, smile, you also retreat."

Qiao Yuchen shouted, and the person rushed forward a few steps.

"Bang..."

A wall falls down along the wall on the right. Now there is only a five-meter hole left.

Da Wang, Er Wang, and Nangong Yixiao controlled the distance of five meters, and as soon as the zombies came in, they quickly killed them.

In just a while, there were already a lot of zombie crystals in the middle box.

Qiao Yuchen hurriedly ran to the middle again, stretched his hand into the box, and as soon as his consciousness moved, the crystals in the box disappeared.

“piu... piu... piu...”

After collecting the crystals, Qiao Yuchen was not idle for a moment, and the five-four system in his hand kept shooting at the zombie group.

When the four of them finished collecting the zombie crystals in the range, Qiao Yuchen directly shrank the wall behind him, shortening the distance by five meters.

"Bang bang..."

Even though the two walls were connected to the five-meter wall, the zombies with the alloy walls were blocked out of the wall again before they could react.

And many of those who piled up and climbed the wall were hung on them by the spikes on the alloy wall, and the hanging zombies blocked the zombies who wanted to come behind.

For a while, Qiao Yuchen and the others firmly held off the zombie attack.

Shrinking the distance by five meters, Qiao Yuchen was not idle, and continued to expand the distance of five meters forward, and Da Wang, Er Wang and Nangong Yixiao and the five of them also harvested the zombies within the five-meter range with a wave of full output.

Da Wang and Er Wang are also dog spirits, and the two of them specialize in picking those strong zombies in the zombie group to attack, and there are many third-level zombies in this huge zombie group.

And the third-level zombies are a disaster for Nangong Yixiao, and they are a disaster. There are big and two kings who are killed in advance, which allows them to survive and have sufficient protection.

Nine of the Blood Ten Guards were killing zombies, and they didn't know anything about Qiao Yuchen's plan, they didn't know how long they would have to kill if they moved forward slowly.

You know, even if it's a big one, it will definitely not be able to hold up for a long time. Not to mention them.

Time passed minute by minute, and when Qiao Yuchen advanced five meters again, he retreated to the box in the middle again, and at this time, there were a lot of zombie crystals piled up in the box.

Qiao Yuchen didn't hesitate at all, his consciousness moved, and the crystal was retracted into the space.

"System, count it, exchange energy points."

"Drop, 185 first-level energy were found, 1850 energy points were exchanged, 63 second-level energy were found, 3150 energy points were exchanged, 5 third-level energy were found, 2500 energy points were exchanged, please confirm whether to exchange..."

"Redeem"

"Drop, the energy points have been successfully exchanged, and the remaining energy points are 13850 points..."

Most of the secondary energy sources in this are killed by Da Wang and Er Wang. And the third-level zombies are all Da Wang, and the second Wang found out in time and killed them, otherwise these five third-level zombies are enough for the Blood Ten Guards and Qiao Yuchen to be wiped out ten times.

Seeing the energy points skyrocketing, Qiao Yuchen couldn't be happy, there were too few energy points, even if Li He and the four of them were crazy about collecting zombie crystals, it was far from enough for Qiao Yuchen to use.

"Drop, it takes 10,000 energy points to exchange for patrol dogs, please confirm if the host can exchange ......"
