Su Chen originally thought that the battle with Pikadi would take at least a month, but unexpectedly the situation suddenly changed and he had to fight.

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

Following Su Chen was Xiao Bai.

After Xiaobai finished eating the brains of Liu Dan, Liu Han, and Yang Rui, he became lazy and wanted to fall to the ground and sleep.

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.

Su Chen will not waste this time in vain, he will carry out a massacre in the suburbs of Nanshi, the area with the highest density of mutated creatures.

Su Chen is convinced that with Pikadi's talent, it is not difficult to advance to the fifth level of evolution. Presumably, Pikadi who successfully advances will have new skills or special skills, and his strength will be significantly improved.

Su Chen thought that with his current combat power, he could still fight against the then Pikadi, but Pikadi's growth rate was much faster than him, and his current combat power was completely inadequate.

If you want to defeat Pikadi, you must be one level higher than him, otherwise the winning rate will never exceed 10%.

Somewhere in the suburbs of Nan City, the area that Su Chen had visited, there were no high-level mutant creatures in this area, but the number of mutant creatures was surprisingly large. Using them to gain experience would be tiring, but there would 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. He believes that he can accumulate 5000 experience in just one and a half hours, and then try to advance.

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

When Su Chen got out of the car and started a bloody massacre with the mutant creature, Xiaobai was still digesting the last Yang Rui, which was huddled in the back seat. No mutant creature that sensed its breath dared to step within its 100-meter radius. .

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

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

In order to increase the winning rate in the battle with Pikadi, he had to train his body from the inside out.

Su Chen's physical body has been strengthened for the third time, and his skin has been able to withstand the sharp claws of first-level zombies. In the melee, he is also wearing a battle armor. Although there are many mutant creatures, none of them can hurt him.

An hour later, as Su Chen moved forward, hundreds of mutated creature corpses appeared on the roadside. There were almost no signs of first-level mutated creatures in these corpses, and most of them were second-level mutated creatures.

Su Chen's attacks were extremely fierce. In the face of his domineering power and absolute speed, no mutated creature could withstand his attacks.

They say they are here for training and to gain experience, but in reality they are purely for gaining experience. None of these mutated creatures can defeat them.

After another ten minutes, Su Chen kicked away the mutated creature in front of him, using all his momentum, he punched the surrounding shrimps, soldiers and crabs to death.

Su Chen's killing finally caused panic at a certain moment. After the bloody baptism, the mutated creatures with a little intelligence suddenly enlightened. They no longer charged blindly, but took their subordinates away from Su Chen.

Su Chen looked at the mutated creatures scattering in all directions, but did not chase them. He began to pant crazily and put his hand on his heart to stabilize himself.

In the battle that lasted for nearly an hour and a half, Su Chen did not use experience potions to restore his physical 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, which resulted in him never really experiencing this body.

Either you use experience potions to heal when you are injured, or you use experience potions to restore your physical strength when you are a little tired. Even all kinds of negative states can be restored with experience potions.

There is no negative effect in using experience potions in this way, but Su Chen's understanding of himself will become worse and worse. At the same time, due to excessive use of experience potions, Su Chen's prediction of danger and his performance in battle will gradually change.

Difference.

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

This is 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 the battle with Liu Dan, Su Chen experienced the consequences of taking the experience potion too slowly, and he also knew the consequences of relying too much on the experience potion, which would have a great impact on his future growth.

Nowadays, Su Chen's heart has not healed yet, but this does not affect the effect of the experience potion. However, Su Chen does not want to use the experience potion until his life is in danger.

He wants to defeat his opponents with his own strength, not the convenience provided by the zombie illustrated book.

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

After the mutated biomass dispersed, Su Chen rested on the spot for five minutes, and then checked his body.

After finding that there was nothing wrong with his body and that his total experience reached 5,000, Su Chen took a deep breath and hesitated a little.

Promotion is risky, and Su Chen is afraid of failure. If the total experience drops to zero, not only will his combat power be in question, but he doesn't know how long it will take to accumulate 5,000 experience points again.

Compared to promotions with unknown success rates, Su Chen prefers the previous promotion conditions. Although the conditions are a little more difficult to complete, at least there will be no promotion failure.

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

Five thousand experience points were quickly invested in the zombie illustrated book. Whether the promotion was successful or not depended entirely on luck.

Su Chen sat there for half a minute, but did not receive any system prompts or any strange feeling. He checked the zombie illustrated book and found no new changes...

Logically speaking, if there is no change and no prompt for half a minute, it means that his 5,000 experience points have been wasted.

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

Even if five thousand experience points were wasted, the system of the Zombie Manual did not give any prompts. Su Chen once wondered whether he had been tricked or sanctioned by the system.

Five thousand experience points is not a small amount. It took Su Chen hard work for more than three months to accumulate it. Seeing that the system was not responding for a long time, Su Chen gradually became unable to sit still.

Su Chen didn't like this silent feeling. He wasn't sure whether the five thousand experience points were wasted or what the Zombie Manual was doing with the five thousand experience points.

As he waited, morning turned to noon, and the dazzling sun shone on Su Chen's battle clothes. Su Chen stood quietly, not waiting for the changes in his body.

On the other side, Xiaobai in the car rarely took a nap. He stretched out his paws to rub his hair and walked leisurely beside Su Chen.

Even though Su Chen stood still, he felt like an ant on a hot pot. He had been restless all morning.

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

Su Chen stood here for a full ten hours, but still didn't get any reply. The five thousand experience points seemed to disappear out of thin air. Su Chen's total experience now is only 79, and the five thousand experience points consumed have not been given.

He brings any effect and influence.

Seeing that the sky was getting dark and there were more and more mutated creatures around, Su Chen put his irritable mood behind him and led Xiaobai to kill here.

Since the 5,000 experience points were wasted like this, Su Chen had no choice but to accumulate 5,000 experience points again in the shortest possible time. When the time comes when he encounters promotion problems, he will not be so decisive in investing the experience in the Zombie Manual.

This battle lasts just one night!

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

After a night of fighting, Su Chen fought his way three kilometers away. He didn't remember how many mutant creatures he killed. He only knew that his hand was no longer his.

After a night of struggle, Su Chen's total experience increased from 79 to 412. 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.

Xiao Bai was not as hardworking as Su Chen. This group of mutated creatures would not benefit him from mutating again, so he followed Su Chen and played with them. When he was satisfied, he helped Su Chen.

From night to day, Su Chen fought until his hands were weak. He looked at the rising sun and felt a little uncomfortable for a while.

Su Chen rested on the spot for an hour, and just as he was about to get up and continue fighting, the familiar sound of the system sounded in his head.

Su Chen was overjoyed. It must be that he was successfully promoted. He did not hesitate and decisively checked the zombie illustrated book.

However, what awaited him was not good news, but a system prompt indicating that he had failed to advance.

This time the system explained in detail the situation of advancing to level six, and no longer displayed unknown like last time.

It turns out that the 5,000 experience points invested previously were not used to advance, but to open up the promotion channel, which did not cost him any experience.

After the passage is cleared, Su Chen's 2,500 experience points will be deducted based on the principle of half points for failure to advance.

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

Every time Su Chen fails to advance, half of his experience will be deducted, which is 2,500 experience points, and his promotion success rate will be increased by 20%.

The reason why the system did not respond so quickly yesterday was because it took a whole day to get through the passage to advance to the sixth level of evolution. It was not until recently that Su Chen's 5,000 experience points were really put into use.

With a 0% success rate, there is naturally no possibility of successfully advancing.

Nowadays, although advancing to the sixth level of evolution does not require hunting mutant creatures of the same level as before, there are additional probabilistic conditions. In the final analysis, the system will not allow Su Chen to advance easily.

It is worth mentioning that every time you fail to advance, the promotion success rate will increase by 20% until it reaches 100%.

This means that even if Su Chen is a non-chief, as long as he is promoted five times and consumes 7500 experience points, he will definitely be promoted successfully.

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

Su Chen breathed a sigh of relief. Although what he got was not good news, it was still better than having no news at all yesterday.

At least Su Chen now has a goal and knows the conditions to advance to the sixth level of evolution. As long as he has enough time and spends up to 7500 experience points, he can advance successfully.

7500 experience points is not a small amount. Su Chen worked hard all night yesterday and only accumulated a little over 400 experience points.

Su Chen summarized his battles. If he fought ten hours a day, with luck, his experience would reach between 600-800. He still has six days to prepare. He must accumulate experience as much as possible and keep trying to advance.

Even if he fails to advance, the 2,500 experience points he spends each time will not be thrown away in vain. These expended experience points will be used to stabilize Su Chen's realm after Su Chen successfully advances.
