Level seven, in this apocalyptic world that has only gone through more than three years, is simply a critical point.

The highest combat power of human beings has only reached the level of level five, and in the face of alien creatures with level seven strength, that is ants versus giant beasts. Once these alien creatures attack the humans under the leadership of the seventh-level alien creatures, it is only a matter of time before they perish.

Even if Qiao Yuchen's current hole cards are now, they will not be able to withstand the attack led by the seventh-level alien creature.

In the middle of the night, under the hazy starlight, Qiao Yuchen finally escaped from Xicheng with his group in embarrassment, standing at the head of the bridge and looking at Xicheng opposite. Qiao Yuchen fell into anxiety.

Now the situation has changed again, the original power situation in Xicheng has changed, he has no way to wait any longer, once the power of the zombies in Xicheng develops again, the outcome is really unimaginable.

"Let's go, let's go back to the base first."

Closing the alloy gate, Qiao Yuchen rushed back to the base with the Blood Ten Guards.

The clean-up work in Yuyang Dongcheng is very smooth, and most of it has been cleaned up after a day and a night. And the work of leaving behind to collect zombie crystals is also going well, and boxes of zombie crystals are piled up in the base.

The corpses of the zombies were also reduced to ashes under the burning fire.

Dust to dust, dust to earth, although I don't know the names of these people, now it can be regarded as resting.

Seeing that Qiao Yuchen was back, Xu Hua was also relieved, a big stone in her heart was put down, every time Qiao Yuchen went out, she would feel uneasy, and now her dependence on Qiao Yuchen is becoming more and more obvious.

Qiao Yuchen stroked his long black hair and walked over with a smile.

"You haven't rested so late?" The words were full of tenderness, and the smile was full of infection, which instantly melted Xu Hua's heart.

Xu Hua's little face was slightly blushing, and he lowered his head slightly: "I'm a little worried about you, I can't sleep." ”

Looking at the woman in front of him who was worried about him, Qiao Yuchen was very moved in his heart, although it was the end of the world, it made him gain a love and a friendship.

A lover, a group of people who are faithful to themselves, this is something he could not have imagined before the end of the world.

"Okay, I'm back safely, you go back and rest first, I still have some things to deal with. We'll have a meeting early tomorrow morning. ”

Under Qiao Yuchen's explanation, Xu Hua reluctantly returned to the house.

Not long after Xu Hua sat down, there was a knock on the door.

Xu Hua opened the door and saw Nangong standing at the door.

"Laughing, what's wrong? Is there something wrong? ”

Nangong smiled and handed over a yellow book in his hand: "Sister Hua, this is what Brother Chen asked me to hand over to you, let you find Uncle Jin to study it, and then teach it to everyone." ”

Xu Hua took the yellow book, there was no word on the paper, and she couldn't tell what it was from the outside, she didn't rush to open it, but asked Nangong directly: "What kind of book is this?" ”

Nangong smiled and shook his head helplessly: "I don't know, Brother Chen said that this is a martial art, and I haven't seen the specifics." ”

Xu Hua's eyes widened slightly, what does martial arts mean, she still understands, martial artists themselves cannot awaken martial arts when they are promoted, and they all need martial artists to study on their own.

Therefore, the difference in combat effectiveness between martial artists will also be very large, and martial artists with a variety of martial arts skills are far stronger than ordinary martial artists, and the more means, the stronger their combat effectiveness.

The quality of the martial artists themselves makes them not like before the end of the world, and they can only focus on one martial art for the rest of their lives. Martial arts are like skills to them. As long as it cooperates with its own force, it will be able to exert its powerful combat power.

The important thing is to practice a lot, and the more skilled you are, the more powerful you will be.

"Okay, I know, I'll find Uncle Jin over in a while, smile, thank you for your hard work, and take care of Yuchen."

Xu Hua put away the yellow book and explained it, and now it is the Blood Ten Guards who stay by Qiao Yuchen's side at any time. Naturally, they should be burdened with security.

Nangong smiled and nodded: "Sister Hua, I know that we will swear to protect Brother Chen." ”

In the warehouse on the basement floor, Qiao Yuchen looked at the boxes of zombie crystals in front of him, and he was a little excited in his heart.

As soon as his consciousness moved, all the zombie crystals in front of him were collected into the system space.

"System, exchange crystals for energy points."

"Drop, 11,875 second-level energy were found, 59,375 energy points were exchanged, 886 third-level energy points were found, 443,000 energy points were exchanged, and 12 fourth-level energy points were found, and 60,000 energy points were exchanged. Please confirm whether the host can redeem it..."

Listening to the statistics of the system, Qiao Yuchen was a little excited in his heart, he didn't expect that after collecting zombie crystals, he would be able to exchange for so many energy points. This was far more than he expected.

It's just that from this, Qiao Yuchen also discovered that there are more than 800 third-level zombies, plus the third-level zombie crystals obtained before, that is to say, the number of third-level zombies has exceeded 100 in that attack alone.

And there are also twelve fourth-level zombie crystals, plus the previous fourth-level zombie crystals, then the number of fourth-level zombies has also reached nearly twenty.

In one attack, there are so many third-level zombies and fourth-level zombies. So if Xicheng hasn't been cleaned up for so long, how many third-level zombies and fourth-level zombies will there be?

Will there be fifth-level zombies, or even higher-level zombies?

Qiao Yuchen had some worries in his heart. Below level five, he can still think of some way to recapture inch by inch, if there are zombies above level five, then the outcome of this battle is really hard to say.

"Redeem."

Don't think too much about it, Qiao Yuchen confirmed the exchange of energy points.

"Drop, the exchange of energy points is successful, and the remaining energy points 778875 points..."

Looking at the energy points counted by the system, Qiao Yuchen smiled in his heart, and more than 770,000 energy points were not less.

Just thinking of the price of the awakening potion again, Qiao Yuchen wilted again.

No longer waiting, Qiao Yuchen's consciousness moved, and the exchange machine appeared in front of him, and his eyes were directly locked on the last awakening potion in the third row.

"Drops, awakening potion, need 300,000 energy points, may I ask if the host can redeem..."

"Redeem."

"Drop, the exchange is successful, get a bottle of awakening potion, please check it by yourself..."

The exciting moment is coming, Qiao Yuchen's heart is already beating at an extremely fast speed, he really doubts that if he continues to be so excited, he will die of overbeat.

Quickly take a few deep breaths to calm your mood and feel the gradually slowing heartbeat, and then turn your eyes to the system space.

In the system space, a colorful crystal bottle stands there, the size of the bottle is the same as the martial artist's awakening elixir, but the potion inside is different, the martial artist and the supernatural awakening elixir are colorless potions, like white water.

However, the Awakening Elixir is like a bottle, rippling with colorful water waves, just by looking at the agility of the potion, you know that this potion is extraordinary.

As soon as the consciousness moved, the awakening potion appeared in his hand, and at the same time, the prompt of the system was also displayed.

"Awakening Elixir: It can awaken ordinary people, with a 40% chance of awakening to become a warrior and a 40% chance of awakening to become an alien. 10% chance to Awaken to become a Homogeneous, 5% chance to Awaken to Multi-Lineage Ability, 4.9999% chance to Awaken to All Five Elements Ability, 0.0001% chance to Awaken to Apocalypse....."

Seeing the previous introduction, Qiao Yuchen's heart was already trembling. This awakening potion is a bit too rebellious. He can understand the warriors and abilities in front of him.

There is actually a chance to awaken into a different martial arts body later, what kind of concept is that, being both a martial artist and a supernatural person, this is very powerful in itself.

Later, there was actually an awakening to become a multi-lineage ability, before Qiao Yuchen may have had scruples, becoming a multi-lineage ability, he couldn't make himself strong, but with the existence of an evolution potion, a multi-lineage ability can also become very powerful.

The five elements that appear later are all the abilities, which are even more powerful than the multi-line abilities, multi-system, maybe two, three systems, but the ability skills that appear are not necessarily the five elements ability.

And the five elements are all different abilities, that is, they will definitely be able to awaken the five elements ability skills, so that the selectivity can be diversified.

At this point, Qiao Yuchen can still accept it, but what the hell is the last apocalypse who has a low chance? He didn't understand it at all.

The introduction of the awakening potion was too long, and this was less than a third of what he had seen, and it already made him unable to calm down.

Then he looked down, and the rest of the content made his heart seem to skip a beat......
