"Squeak!~~~"

The nature of animals is that the seriously injured mutant mouse no longer fights with Bai Cen. When she repels Bai Cen, she turns around and wants to escape. However, it may be because she is not very adaptable to the lack of an eye. She is clearly running towards the direction of the gate, but as she runs, she deviates from the track and hits the gate at once.

"Damn it, you can't even understand that you run away, so don't run away, I'll give you a knife!"

Originally, even if the mutant rat was injured, Bai Cen still couldn't catch up with him if he wanted to escape. After all, if the mouse drilled into the pipe, Bai Cen had no choice. But it was just so coincidental that the mutant rat with only one eye was left to go on a special arc. This undoubtedly gave Bai Cen a chance to catch up with the mutant rat in three steps and pull out the Tang sword.

"Squeak!~~~"

The moment the Tang sword was pulled out, it undoubtedly caused great damage to the mutant mouse again, and its tail was thrust towards Bai Cen again.

Bai Cen was prepared for a long time. With his legs exerted force, his body had jumped into the air, and easily avoided the attack of his tail at a distance of two meters. At the same time, Bai Cen used the power of the falling air to aim at the head of the mutant mouse and stabbed the mutant mouse in the opposite direction with a knife.

After struggling for a few times, the mutant mouse finally kicked his legs and completely left the world.

"Congratulations on completing the hidden mission, killing the first mutant creature, obtaining 10 attribute points, 100 energy points, obtaining a random ingredients, and obtaining one primary enhanced fossil."

While killing the mutant mouse, Bai Cen's ears also heard the unique reminder from the ingredient supplier. Although it was still dry and without any emotion, it made Bai Cen feel particularly wonderful.

"Isn't the harvest this day a little too rich?"

The prompt from the ingredient supplier made Bai Cen feel a little scared. He said that things are impermanent and there will be demons. The harvest today is so rich that Bai Cen can't believe it. Not only did he obtain the most energy points in history, but he also completed a hidden task, which really made Bai Cen feel a little scared.

But thinking about it, it’s okay to say something when burning zombies, after all, there is the help of the Molotov cocktail. But in the battle just now, it almost cost Bai Cen’s life, and it’s natural to gain some gains.

"What if he doesn't matter, this end of the world has come. What else can I have to fear? No matter what, it's always a good thing to increase your strength. Put away what I deserve first."

"exchange."

It has to be said that after the end of the world came, Bai Cen can be said to have undergone earth-shaking changes. He used to be, but even a little hooligan dared to offend him, and in just a few days, he had already developed super psychological qualities.

Of course, the reason for all this is because of strength. Compared with the scholar who was powerless before, Bai Cen now has the capital to stand at the top of the world, and the continuous battles have slowly adapted to the new environment of the end of the world.

"Congratulations on your successful redemption and you will get 2 energy points."

The sound of the ingredient supplier sounded, and the corpse of the originally mutant mouse disappeared instantly, leaving only a crystal clear crystal core. However, these did not attract too much attention from Bai Cen. Instead, the prompt sound of the ingredient supplier made Bai Cen stunned.

"The mutant mouse can actually exchange two energy points. Why is this? Could it be that this mutant mouse is already a second-level end-of-life creature?"

When Bai Cen used to exchange zombies, he only had a little energy point, but this time there were two points. The first thing Bai Cen thought of was that this mutant mouse had become a second-level end-of-life creature.

Of course, Bai Cen would not know about this kind of problem, so Bai Cen decided to ask an expert for inquiries.

"Dear Master, if it is a second-level creature, you are no longer bones. And if it is a second-level creature, how could it be exchanged for only two energy points? That mutant mouse, at most, is a first-level second-level creature, which is far worse than the second-level creature."

This expert is undoubtedly Xiao You, but when Bai Cen asked if the mutant mouse was a second-level creature, Xiao You almost fainted from laughing.

"Level 1 and second-grade creatures? How many grades are there in the first-grade creatures? How many grades are there in the first-grade creatures?"

When Xiaoyou finished explaining, Bai Cen became messy in an instant.

But thinking about it is true, if you can become a second-grade creature with the strength of a mutant mouse, it would be too sorry for the level divided by the ingredient suppliers.

"Of course I have to divide it. Not only the first-level creatures, but even the seventh-level creatures are divided into levels. After all, even the seventh-level creatures are divided into strengths and weaknesses. Just like Master, you now have the strength of first-level and second-level, but even if your strength is doubled, you are still a first-level creature. It's just that your strength has been barely improved from second-level to third-level, which is that simple."

"As for the grades divided into each level, the grades are divided into seven grades, just like the grades."

Xiao You's explanation is very simple, and the examples are also very vivid. It's just that the protagonist of the example makes Bai Cen a little crying.

"Okay, I understand, there is another question. When I completed the hidden mission, I obtained a primary strengthening fossil. What's the use of this thing?"

In all the hidden tasks that have just been completed, Bai Cen only has no knowledge of this primary strengthening fossil and does not know what to do.

"Basic enhanced fossils are good things. Strengthened fossils are used to strengthen equipment. Equipment strengthened by the enhanced fossils will be attached with an attribute and have the opportunity to increase a level. That is to say, if you use the enhanced fossils to strengthen the Tang sword in your hand now, then your Tang sword may evolve from the current level 0 item to the first item, and then add an attribute."

Xiao You is worthy of being an expert, and any problem is not a problem for her.

"There are such good things. Then I can make more enhanced fossils in the future, so that I can turn the Tang sword into a level seven item?"
