Su Chen originally thought that the battle with Pikadi would be at least a month later, but he didn't expect the situation to change abruptly, and he had to fight.

The next day, in the early morning of the ninety-ninth day of the outbreak of the end times, the sun rose in the east, and Su Chen had rushed from Longcheng to the outskirts of Nanshi.

Following Su Chen's side, there was also Xiaobai.

After Xiaobai finished eating Liu Dan, Liu Han, and Yang Rui's brains, he became lazy and lazy, and he couldn't wait to fall asleep.

After the battle with Liu Dan, Su Chen's heart was damaged, and it would take at least three to five days to completely heal.

This time Su Chen will not be wasted in vain, he wants to carry out a massacre on the outskirts of Nanshi, the area with the highest concentration of mutated creatures.

Su Chen was sure that with Picardi's talent, it would not be difficult to advance to the fifth level of evolution, presumably Picardi, who had successfully advanced, would have new skills or special skills, and his strength would be significantly improved.

Su Chen thought that his current combat power could still fight against Pikadi at that time, but Picati's growth rate was far faster than him, and his current combat power was completely insufficient.

If you want to beat Picardi, you must be one level higher than him, otherwise the win rate will definitely not exceed 10%.

Somewhere on the outskirts of Nanshi, the area where Su Chen had been, there are no high-level mutant creatures in this area, but the number of mutant creatures is surprisingly large, and using them to brush up on experience, although it is tiring, there will be no risk.

At present, Su Chen's total experience amount is 4880, which is only 120 away from the experience required for the next level, and he believes that in just one and a half hours, he can accumulate 5000 experience, and then he will try to advance.

As for whether the result was a success or a failure, Su Chen had no clues.

When Su Chen got out of the car and started a bloody slaughter with the mutant creatures, Xiao Bai was still digesting the last devoured Yang Rui, it was huddled in the back seat, and none of the mutant creatures that sensed its breath dared to step into its radius of 100 meters.

In this battle, Su Chen did not use a gold-breaking blade, and purely used his hands to solve the opponent.

For Su Chen, his best weapon is himself, and all other cold weapons will hold him back.

In order to increase his chances of winning the battle against Picardi, he had to train his body, all from the inside out.

Su Chen's body has been strengthened three times, and his skin has been able to resist the claws of first-level zombies, and in the melee, there is a battle armor draped, although there are many mutant creatures in this group, none of them can hurt him.

An hour later, Su Chen advanced all the way, and there were hundreds of corpses of mutant creatures on the side of the road, and these corpses could hardly find the shadow of first-level mutant creatures, and most of them were second-level mutant creatures.

Su Chen's attack was extremely powerful, and in the face of domineering strength and absolute speed, no mutant creature could resist his move.

said that he came here to train, and by the way, he brushed experience, but in fact, it was purely experience, and none of these mutated creatures could fight.

After another ten minutes, Su Chen kicked away the mutant creatures in front of him, and his momentum was full of momentum, and the surrounding shrimp soldiers and crabs were punched to death.

Su Chen's killing finally caused panic at a certain moment, and the mutated creatures with a little wisdom suddenly opened up after a bloody baptism, they did not charge blindly, but took their subordinates away from Su Chen.

Su Chen looked at the mutated creatures scattered everywhere, and didn't chase them, he began to pant frantically, pressing his hand on his heart to stabilize himself.

In the previous battle of nearly an hour and a half, Su Chen did not use the experience potion to recover his strength and injuries.

Su Chen found that since he had the experience potion and had enough experience, he relied too much on the experience potion, resulting in him never really experiencing this body.

Either you use experience potions to heal as soon as you are injured, or if you are a little tired, you use experience potions to restore your strength, and even all kinds of negative states are also restored with experience potions.

There is no negative effect on using experience potions like this, but Su Chen's understanding of himself will get worse and worse, and at the same time, because of the excessive use of experience potions, Su Chen's prediction of danger and performance in battle will gradually deteriorate.

These are not very important, what is really important, Su Chen is afraid that one day he will suddenly not be able to use the experience potion.

It's not impossible, since the Zombie Illustrated Book can provide him with the right to use the experience potion, it is possible to take it back one day.

After fighting with Liu Dan, Su Chen experienced the consequences of the experience potion being slowed down, and he also knew that he relied too much on the experience potion, which would have a great impact on his future growth.

Now, Su Chen's heart has not healed for the time being, but this does not affect the effect of the experience potion, but Su Chen is not dying, and he does not want to use the experience potion.

He wanted to defeat his opponent with his own strength, not the convenience provided by the Zombie Illustrated.

Although the experience potion was now a part of Su Chen's body.

After the mutant group dispersed, Su Chen rested in place for five minutes, and then checked his body.

After finding that there was no problem with his body and accumulating a total of 5,000 experience, Su Chen took a deep breath and hesitated slightly.

There is a risk in promotion, Su Chen is afraid of failure, if the total experience falls to zero, not only will he have problems with his combat power, but he wants to accumulate 5000 experience points again, I don't know when.

Compared with the promotion with an unknown success rate, Su Chen prefers the previous promotion conditions, although the conditions are more difficult to complete, but at least there will be no failure to advance.

However, this road Su Chen had to go sooner or later, and Su Chen had no choice.

5,000 experience points were quickly put into the Zombie Illustrated Book, and the success of the promotion depends on luck.

Su Chen sat in place for half a minute, he didn't get a system prompt, and he didn't have a strange feeling, he checked the zombie illustrated book, and there were no new changes...

It stands to reason that half a minute without change and no hint means that his 5,000 experience points have been lost.

Thinking of this, Su Chen's heart twitched, and he suddenly felt uncomfortable and unhappy.

Even if the five thousand experience was lost, the system of the Zombie Illustrated Book did not make any prompts, and Su Chen once wondered if he was cheated or sanctioned by the system.

Five thousand points of experience is not a small amount, this is something that Su Chen has accumulated after more than three months of hard work, seeing that the system has not responded for a long time, Su Chen gradually couldn't sit still.

Su Chen didn't like this feeling of silence, he wasn't sure if the five thousand experience was in vain, or if the zombie illustrated book was doing with the five thousand experience.

He waited, the morning turned to noon, the dazzling sun shone on Su Chen's battle suit, Su Chen stood quietly in place, and did not wait for the change in his body.

On the other side, Xiaobai in the car rarely didn't take a nap, he stretched out his claws and rubbed his hair, and walked leisurely around Su Chen.

Don't look at Su Chen standing still, his heart is like an ant on a hot pot, he has been irritable all morning.

At Su Chen's stop, the sun that was bright not long ago quickly dimmed, and then the sun set, and the moonlight shone on Su Chen's somewhat tired face.

Su Chen stood for ten hours, but he still didn't get any reply, the five thousand points of experience seemed to disappear out of thin air, Su Chen's total experience was now only 79, and the five thousand points of experience consumed did not bring him any effect and impact.

Seeing that the sky was dark and there were more and more mutated creatures around, Su Chen lingered his irritability and took Xiaobai to kill here.

Since 5,000 points of experience are wasted like this, Su Chen has no choice but to accumulate 5,000 points of experience again in the shortest possible time, and when he encounters the problem of promotion, he will not be so decisive to vote his experience to the Zombie Illustrated.

This battle is one night!

In the early morning, the sun, which was blocked by the mountains, brought its light to the land under Su Chen's feet, and Su Chen sat on Xiaobai's soft fur and closed his eyes to rest.

After a night of fighting, Su Chen fought all the way out of three kilometers, he didn't remember how many mutated creatures he had killed, he only knew that his hand was no longer his.

After a night of struggle, Su Chen's total experience had risen from 79 to 412, and if it weren't for the fact that there were many first-level mutant creatures, Su Chen's total experience would have increased to at least 500 or more.

Xiaobai didn't fight like Su Chen, and this group of mutated creatures didn't do it any good for it to mutate again, so it followed Su Chen's side, played with them, and helped Su Chen when he had a good time.

From night to day, Su Chen was soft-handed, and he looked at the gradually rising sun, and his heart felt a little uncomfortable for a while.

Su Chen rested in place for an hour, and was just about to get up to continue the fight, when a familiar prompt sound sounded in his head.

Su Chen was overjoyed in his heart, could it be that he had succeeded in the promotion, he did not hesitate, and decisively consulted the zombie illustrated book.

However, what awaits him is not good news, but a system prompt that he has failed to advance.

This time, the system details the progress to level 6, and it is no longer displayed as unknown as in the previous time.

It turned out that the 5,000 points of experience he had invested earlier were not initially used to advance, but to open up the promotion channel, which did not consume any of his experience.

After the channel is opened, Su Chen's 2,500 experience points will be deducted according to the principle of halving the promotion failure.

Su Chen's original promotion probability was unknown, but in fact, the success rate of promotion was 0%.

Every time Su Chen fails to advance, half of the experience will be deducted, that is, 2500 experience points, and the success rate of promotion will be increased by 20%.

Yesterday, the system didn't react so quickly, because it took a whole day to open the passage to advance to the sixth level of evolution, and it wasn't until not long ago that Su Chen's 5,000 points of experience were really put into it.

With a success rate of 0%, there is naturally no possibility of successful promotion.

Now, although it is not like the need to hunt mutant creatures of the same level as the original level of evolutionary beings, there are more probability conditions, in the final analysis, the system will not let Su Chen advance easily.

It is worth mentioning that every time you fail to advance, the success rate of promotion will be increased by 20% until 100%.

It means that even if Su Chen is a non-chief, as long as he advances five times and consumes 7,500 points of experience, he will definitely succeed in qualifying.

Su Chen thought that his face should not be so dark, but his luck would definitely not be particularly good, and he was already mentally prepared to advance twice more.

Su Chen breathed a sigh of relief, although it was not good news, it was better than no news yesterday.

At least Su Chen now has a goal and knows the conditions for advancing to the sixth level of evolutionary, as long as he has enough time, it will cost him a maximum of 7,500 experience points to successfully advance.

7,500 points of experience is not a small amount, yesterday Su Chen worked hard all night, and the experience has only accumulated more than 400 years.

Su Chen summed up his battle, if he fought for ten hours a day, if he was lucky, the experience could reach between 600-800, he still had six days to prepare, he had to accumulate as much experience as possible, and keep trying to advance.

Even if he fails to advance, the 2,500 experience points he consumes each time will not be wasted, and these spent experience points will be used to stabilize Su Chen's realm after Su Chen's successful promotion.

The Zombie Illustrated Book and Su Chen are mutually beneficial, and they will not only take advantage of Su Chen.
