Chapter 5: New ability

Finally, after avoiding several attacks, Chu Xuan was surprised to find that the speed of the mutant zombie had actually slowed down significantly.
It seemed that he was also aware of the decline in his state, and the bone-blade zombie finally stopped.
However, the state of the mutant zombies was already extremely bad. Some of the healed areas on the edge of the abdominal wound had been torn again, and dark red blood kept pouring out, and the pale face was even more pale at this time.
He breathed out gently, calmed down the violently beating heartbeat in his chest, Chu Xuan held the laser long sword and slowly pushed towards the bone-blade zombie.
The latter was slowly backing away at this time, with a retreat in his eyes.
"not good."
Seeing this, Chu Xuan secretly said a bad word in his heart, and what happened afterwards was not beyond his expectations.
I saw that the mutant zombie turned his head and got into the corridor behind.
"Where do you think you can go!"
Seeing this, Chu Xuan rushed to catch up immediately. After all, there is no reason for a cooked duck to fly away.
"Roar!"
A few minutes later, a cold light suddenly appeared at a blind corner of the corridor.
Looking at the head that fell to the ground, Chu Xuan shook his head and whispered, "System, fuse."
The scene that happened before was staged again, and the body of the mutant zombie turned into a little glow and merged into Chu Xuan's body.
"The host fuses second-order mutant zombies and gains additional attributes, 35 speed points, 15 power points, 20 physical points, and 10 mental power points. Gain additional ability: Bone Blade."
"35 points speed, so much?"
Hearing the system's voice, Chu Xuan smacked his lips and exclaimed.
He had previously expected that the mutant zombie was a speed-type mutation, and it seemed that the attributes obtained after the fusion had a great relationship with the zombies that were fused.
However, the words of the system did not stop there, and the cold voice continued.
"All the attributes of the host are more than 10, and it is successfully advanced to the second level."
"The host advances to the second level, gains abilities, mental saves: the host is immune to all mental attacks."
The sound of the system sounded, and Luo Chuan felt as if his whole body had been sublimated, and a sense of invigoration that was difficult to express in words surged across his body.
This is the biochemistry of the life stage and the transition of the life level!
"Is this the strength of Tier 2?"
Chu Xuan squeezed his fists, feeling the strength that was several times worse than before, and a smile appeared on the corner of his mouth.
It seems that the goddess of luck is indeed standing by his side, if it weren't for the bone-blade zombie's serious injury and unhealed, it would not be Chu Xuan's turn to pick this cheap.
And he also gained new skills, mental immunity, and he is directly immune to all mental attacks.
In other words, if you encounter a zombie or a person with a spirit system, you will be invincible by nature.
"By the way, the system requires the average of all attributes to reach 10 to be promoted to the second rank, so does the third rank need 100?" Chu Xuan suddenly thought of something and couldn't help asking.
"Yes, before the fifth level, the attribute points required for each advancement need to be ten times that of the current level." The system responded faintly, "but the host advancement requires each attribute to reach the critical value of the attribute."
Sure enough. Upon hearing this, Chu Xuan also nodded clearly.
He has a system and it is understandable that it is harder to advance than others.
"What about after Tier 5?" Chu Xuan couldn't help asking.
"The host has insufficient permissions to query."
The system's words made him laugh wryly. It seems that improving his current strength is the most important thing.
However, his attention quickly shifted to other places. The previous system reminded him that he clearly remembered that he had obtained the bone blade of the bone blade zombie.
It's a pity that Chu Xuan didn't get the mutation of the bone-blade zombie's legs, which is also a little regrettable for him.
As if instinctively, under Chu Xuan's thoughts, the muscles on his arm actually squirmed slowly, and a bone blade that looked like a sharp blade slowly emerged from it.
The edge of the bone blade shone with dazzling cold light, and its sharpness can be imagined.
