After understanding the specific conditions for this promotion, Su Chen made a slight adjustment, and after his breath recovered, it was convenient for Xiaobai to continue to slaughter the mutated creatures nearby.

Su Chen intended to fight, and the mutant creatures nearby didn't even have a chance to escape, and all the prey he targeted died under Su Chen's thunderous attack.

The boring battle lasted for a whole day, from day to night, Su Chen only rested for three hours, and the rest of the time was fighting.

For a while, Su Chen's body couldn't support it, so he used the experience potion to restore his strength.

If it weren't for the fact that time was tight and experience points were really lacking, Su Chen didn't want to use experience potions to destroy the breakthrough in his body.

After a whole day of fighting, Su Chen's experience points increased from the original 2912 points to 4010 points.

Nearly fifteen hours of high-intensity combat took more than a thousand experience points, which is not much.

When Su Chen finished resting again, there was no trace of the mutant creature around.

Under Su Chen's frenzied slaughter, the mutant creatures died and ran, and after a day, the nearby two miles had become the dead domain of the mutant creatures.

Su Chen sensed for a moment to make sure that there was no longer a mutant creature in his perception, and he quickly returned to Z3 off-road, turning his destination to the center of Nanshi City.

Although the center of Nanshi is not the place with the highest concentration of mutant creatures, the mobility of mutant creatures is the highest, and there are almost endless mutant creatures in the city center, which is the best place for Su Chen to practice.

Two hours later, in the center of Nanshi, Su Chen and Xiaobai's killing road began.

With the combat power of Su Chen and Xiaobai, it is rare to be able to find a real opponent in Nanshi, and one person and one beast are slaughtered, and none of the mutated creatures encountered escape the clutches.

In this battle, from morning to dusk, Su Chen panted heavily, looked at 5001 experience points, and while recovering his strength, he was ready to fail to advance.

On the other side, Xiaobai was lying leisurely at Su Chen's feet, and he was not tired of today's battle.

Half an hour later, Su Chen's breath was calm and his mind was stable, he didn't hesitate, and put another 5,000 points of experience into the zombie illustrated book.

This time it didn't make him wait for a whole day, but in just two seconds, the system prompted that the promotion failed.

Su Chen checked himself from the zombie illustrated book again.

Sure enough, Su Chen still had 2,501 experience points left, and at the same time, the success rate of re-promotion increased to 40%.

Su Chen's luck was obviously not good, he took a deep breath, clenched the gold-breaking blade again, didn't eat dinner, and went straight to the north for a mile, and started the bloody slaughter again.

This kind of high-intensity combat, even if there is an experience potion to restore physical strength, Su Chen's body will be unbearable sooner or later.

The experience potion can indeed restore Su Chen's energy instantly, but continuous use in a short period of time will cause Su Chen's physical fitness to become worse and worse, and the number of times he uses it will become more and more frequent.

Su Chen quickly discovered this, he knew that some things could not be done quickly, and he knew the truth that if you want to hurry, you can't reach it.

Su Chen did not continue to fight, but planned to sleep well for eight hours, and Xiao Bai on the side naturally became a guard to protect Su Chen to rest.

On the second day, at 4 o'clock in the morning, Su Chen's biological clock woke him up from sleep, Su Chen sighed, sensed this body, and found that the battle of the previous two days was indeed effective, his body was much stronger than before, and the speed of physical recovery had also increased.

These are the benefits of rarely using experience potions and fighting all the time in the Extreme.

Su Chen cheered up, simply finished breakfast, and let Xiaobai sleep alone, while he set off again to continue his slaughter of mutant creatures.

Su Chen's slaughter of mutant creatures for several days in a row, and he stayed with Xiaobai all the time, causing him to be contaminated with a special aura.

This breath is not felt by ordinary immunizers and evolutionaries, only mutated creatures can feel it, it is like the breath of natural enemies.

Today, Su Chen's harvest is not good, once he approaches a certain area, a mutant creature with a little intelligence will lead his subordinates away from Su Chen, causing Su Chen to only kill a piece, and he will not be able to detect any mutant creature in his perception.

As a result, Su Chen's massacre had to slow down, and his third promotion was delayed.

Another day passed, and the last hundred and third days of the end of the world broke out, and there were only three days left before the war with Picardi.

Early in the morning, Su Chen, who had slept all night, woke up from his sleep, and the high-intensity combat for several days made him a little tired of killing, he was not a pervert who naturally liked to kill, and the killing day and night made him very tired.

However, Su Chen had no choice, and before dawn, he ran around the downtown area of Nanshi again with a knife.

Because the smell of blood on Su Chen's body was too strong, the mutant creatures began to flee in all directions before they could see Su Chen, making it more and more difficult for Su Chen to hunt the mutant creatures.

Su Chen never thought that things would turn out like this, and the mutant creatures with intelligence would run away in the first place.

At noon, after nearly a day and a half of fighting, Su Chen finally accumulated 5,000 points of experience.

He sat on the pile of corpses and gasped for breath, praying silently in his heart, hoping that this time he would be successful.

Soon, the reply to the failure of the promotion sounded in Su Chen's mind again.

Su Chen's 2,500 points of experience were wasted again, and in exchange, the success rate of 40% was increased to 60%.

Su Chen looked at the corpse mountain under his feet with a little headache, these days the mutant creatures are killing fewer and less, and most of them haven't seen him yet.

There are still two days to go, at most let him be promoted once, if the promotion is not successful, he and Picardi are afraid that the battle will be more than lucky.

Although the conditions for this promotion depend on luck, it is actually not difficult compared to hunting several or even dozens of mutated creatures of the same level but different types.

If Su Chen was asked to hunt ten mutant creatures of the same level but different types, let alone giving him seven days, even if he was given a month, he might not be able to find ten mutated creatures of the same level of different types.

To put it mildly, Su Chen's luck is not too bad.

After failing to advance, Su Chen didn't rush to find the mutant creature, he still had the last 50 hours left, this time was enough for him to advance again at most, he glanced at the corpse mountain under his feet, and walked down slowly.

Since it was determined that the remaining time was not enough to advance twice, Su Chen no longer worked hard to find mutated creatures.

Su Chen's search for mutated creatures slowed down, but the killing aura on his body only increased, and his momentum became more and more aggressive after being tempered.

Xiao Bai has been by Su Chen's side these days, listless all day long, Su Chen did not look for mutated creatures of the same level, Xiao Bai did not have suitable prey to eat, and he once regretted not keeping Yang Rui's head at the beginning.

After 42 hours, Su Chen finally accumulated 5,000 points of experience, his mental state was much better than the first two days, and the pressure in his heart, after these few days of self-comfort, was almost no more.

In the Z3 off-road, Su Chen leaned back on the main driver's seat, he sensed his body, and he was very good in both mental and physical condition.

Su Chen took a deep breath, didn't think much about it, and invested 5,000 points of experience again.

This time, in less than half a second, Su Chen received the news that he had failed to advance!

The bad news came too quickly, and it didn't give Su Chen a chance to breathe at all.

I have to say that Su Chen's luck is too bad in terms of the probability of promotion, 80% of the probability can fail, if there is no 100%, Su Chen may continue to fail.

Su Chen shook his head secretly, this result had long been within his expectations, although the ending was very unsatisfactory, but this was a fact, and he had to accept it.

There are only a few hours left before the battle with Picardi, and it is impossible to complete this time, not to mention accumulating 5,000 experience points, even if you increase 1,000 experience points.

Since the heavens didn't want him to succeed in the promotion, Su Chen had no other way but to accept it.

Su Chen spent nearly seven days and invested 10,000 points of experience! In the end, there was no benefit except for a slight increase in physical fitness.

If you know this, it's better to look for mutated creatures of the same level and improve your actual combat experience.

At the moment, there was not enough time, so Su Chen stepped on the accelerator and rushed to the Sunset God Sect.

Xiaobai on the side is not in a leisurely appearance, it has seen the combat power of Picardi, and knows that Bicardi is powerful, if Su Chen is defeated, it will sacrifice its life to fight Picardi.

When Su Chen arrived near the Sunset God Sect, it was still dark, and there were still six hours before the appointed time.

Su Chen asked Xiaobai to be vigilant, and he began to rest, he personally experienced the strength of Pikadi, and a good state was very important.

After a few hours, the dark night began to shine, the sun rose in the east, and the time to reach the battle became shorter and shorter.

Picardi made an appointment to fight with Su Chen alone, but Su Chen didn't plan to go alone.

After all, there are a few cronies around Pikadi who he has read the information, although his strength is much weaker than him, but there are two who are likely to be promoted to the fifth level of immunity, once they are successfully promoted, Su Chen's situation will be quite disadvantaged.

Take Xiaobai with you, even if you can't help him, at least you can drag Picardi's right-hand men.

In the last hour of the battle, Su Chen took Xiaobai out of the car, although the seven days did not make him much stronger, but at least his heart injury was completely healed, and his physical fitness also became stronger, but it was not without gain.

Since the Sunset God Cult was attacked by Su Chen's base camp, the defense of the headquarters has been much stricter than before.

Su Chen didn't deliberately hide himself, the strong fight, first of all, the momentum can't be lost, this is Bicardi's territory, even if Su Chen loses this battle, he will overwhelm Bicardi in momentum.

The leader of the city guard quickly discovered Xiao Bai, and then noticed Su Chen.

As early as a few days ago, Picardi ordered to greet Su Chen, and Su Chen's appearance was almost drawn by more than a dozen leaders of the Sunset God Sect with their eyes closed.

Seeing Su Chen coming, the leader stationed at the west gate ran to greet him, but he didn't know that an hour later, Su Chen and Picardi would fight, which would affect the development of the two large camps.

Pikadi gave Su Chen enough face, Su Chen entered all the way through the west gate, without any obstruction, and all the soldiers who saw Su Chen, whether they were soldiers or leaders, bowed down respectfully.

After the battle with Picardi, Su Chen knew that he was upright and upright, and if he said one-on-one, it must be one-on-one, even if this was Picardi's home field, he would not use his cronies to besiege Su Chen.

Of course, even if Picardi doesn't pay attention to integrity, Su Chen has to meet it with his head.

Now that Ye Yao has become a prisoner of Pikadi, even if this battle is certain to die, Su Chen will give up his life to fight him.
