As Kong Ling expected, the system will refresh the monsters at 6 o'clock every morning. The number of zombies did not change much on the fourth day, but the number of zombie dogs increased sharply. When he hit, almost most of the zombie dogs were zombie dogs. The number would definitely make people feel numb to their scalp. However, the vitality of zombie dogs is similar to that of zombies, and high voltage electricity can still be easily killed.

Without this trap, Kong Ling had to survive and could only hide in a corner and wait for time to pass. It was impossible to go out and act. On the fourth day, the number of zombies and zombie dogs had completely eliminated people walking outside, unless there were armored vehicles.

On the fourth day, he got 4230 points. Every day, he got a double increase in points, as long as he has the ability to kill them.

On the fifth day, mutant zombies appeared, and they could crawl on the wall at a speed of at least 3 points. If Kong Ling had the current ability, it would be equivalent to death. When this mutant zombie jumped off the wall outside the mall and landed above the power grid, the voltage lasted for a minute and a half, and the mutant zombie's whole body was so electric that it was not dead yet.

It was not until about 2 minutes that the mutant zombie's body was burned and fell into the safe area in the middle of the power grid that stopped. A mutant zombie had 500 points, but Kong Ling felt that 500 points were considered small. Such terrible vitality was definitely as difficult as climbing the sky with bare hands, even if there was a gun. It was really difficult to kill one.

Kong Ling stayed not just to win points, but also to observe the abilities of these monsters. Mutant zombies recovered their vision like ordinary people, and their hearing was more sensitive. They were not able to see their sense of smell at present. On this day, he killed 6 mutant zombies and a large number of zombies. Instead, the number of zombies became smaller. Including 10 minutes per hour, he got a total of 6,553 points.

On the sixth day, an amazing mutant dog appeared, with a body as big as a cow, with at least 5 points in speed, and looked like a tiger, with an intelligence similar to an ordinary dog, and had already known the danger, and he appeared next to the power grid for a long time without pounced on it.

Kong Ling used various bloody smells to stimulate it, and with a wooden stick, the mutant dog rushed up and hit the power grid. The electric sparks immediately exploded, causing the mutant dog to scream, the voltage sucked it firmly, and the fur was burned first. But even so, the mutant dog was still not dead. After the burning surface of the whole body was like coke, the transformer here could finally not bear the burden for several days, and the entire transformer burned out. Kong Ling took the opportunity to hide back to the distribution room immediately. At the moment when the door was closed, he saw the mutant dog stand up again, and his body actually stretched out black tentacles, which looked even more terrifying.

Immediately afterwards, there was a sound of collision outside the door. Fortunately, the iron door of the distribution room was enough to get to know each other. After continuous impact, the door was slightly deformed. At this time, the outside became quiet. Kong Ling breathed a sigh of relief and immediately touched the bracelet on his left hand. The attribute interface appeared in front of him. However, the attribute interface is currently yellow, which proves that he has not completely escaped from safety. He needs to wait until the interface is green before he can exit.

The interface colors are divided into safe green, alert yellow, dangerous red, and near death black.

After three minutes, after the interface turned green, he immediately pressed to pass the level. There is no high-voltage power grid now, and he is completely seeking death. Such electric current cannot kill the mutant dog, so he doesn't have to think about the fruit knife in his hand.

He only felt a lit up in front of him, and there was white light around him. After the light disappeared, he appeared in a very small house with only one bed and nothing else.

There is a beam of light in the middle of the house, and the light is very soft. This is the Heart of the World Tree used by each reincarnator to exchange items. Of course, it is just a phantom and can only be used to exchange.

At this time, the Demon Princess appeared in front of him, patted his shoulder with a look of surprise and said, "Kong Ling, you are so awesome, do you know, you broke the record."

"Breaking records? Is there still a record of the length of life?"

"Of course, before you, the maximum test time for novices is 5 days, 1 hour, 24 minutes, 37 seconds. And you are 6 days, 3 hours, 14 minutes, 21 seconds, which is more than a day. There is a great reward for breaking the record, but unfortunately it is just a test for novices. If it is normal, you will definitely make a lot of money."

"It's better than not. Now that I've completed the novice test, what should I do?"

"You see the light column in the middle. Just talk to him directly. He will recommend you the most suitable things for you. By the way, let's take a look at the record-breaking prize you get. I'm really looking forward to what it will be. Generally, the system will give you the most suitable things based on your performance, and there will be no unusable things."

Kong Ling just said to the light pillar to receive the record-breaking reward. He saw a few golden lights in front of him, "Congratulations on creating a new record", and then these words became a treasure chest full of gems.

"Why are you still standing there? Touching the box is so exciting. This is the first time I have met my servant who can break the record. I will definitely defeat those hateful women this time, hum." The Demon Princess looked excited.

Kong Ling touched the treasure chest and saw that after the box emitted golden light, a half-meter-long short knife appeared, which turned into a ball of black light and flew to Kong Ling's hand. The whole knife was black, with very small golden patterns on the blade, and the blade was also pitch black and did not look particularly sharp. The knife handle was made of black unknown material, and these fine lines were carved on it, so I don't know what it was.

An interface appears above the short knife, showing the basic information of the short knife: black gold short knife, magic weapon, unknown level and unknown ability.

"Sir, this is the reward for breaking records? Why does it look like an ordinary knife?" Kong Ling held it in his hand and waved it a few times, and it felt like an ordinary knife.

The Demon Princess was also strange. She only knew it was a magic weapon. She reached out to take it to take a look. The moment her finger touched the hilt, a black current rushed out. The Demon Princess screamed, and her hand immediately retracted. The middle finger she touched was actually half-calorized.

She was sweating profusely in pain, and Kong Ling said in surprise: "Your hands are fine."

"No... It seems that only you can touch this knife. Anyway, you can use it first. I'll go to the Demon Palace to check it out and see what it is. Be careful in the future and get more points. You can exchange anything you want here. Give you a suggestion, you must be specialized in abilities. If you have too many skills, you will kill you in seconds. This is different from your world. It's not that there are too many skills and no one can suppress you. If you have limited points, you will only drag you down. Only by exerting a certain ability to the limit can you stand at the top of the pyramid. I'll leave first, goodbye."

"You haven't told me what your name is?"

"Just call me Nina." After she said that, her body turned into black light and disappeared.

Kong Ling saw that Nina must have discovered that this black gold short sword was unusual, otherwise she would not have gone so urgently. She must have wanted to know the origin of this weapon.

Then he said to the light pillar to check the exchange items. A product interface appeared in front of him, with various categories of things, from cold weapons to hot weapons, and even super weapons that surpass Earth technology. There are also many things that are available in animations and movies. The number is so large that he can't finish it even if he can't finish it for several days.

In addition to equipment and props, there are also various martial arts, superpowers, bloodlines, and improvements in the three attributes of strength, physique, and speed. Magic energy is a general term for mana, true qi, chakra, internal strength, etc., but there is no direct improvement here, and it seems that special conditions are required.

After getting familiar with the redemption system here, he was about to redeem when a voice suddenly came out: "Wait."

Kong Ling was surprised why there was someone coming back. A green spot of light appeared next to him, and then the elf she had met before appeared. However, it has now become a small elf that was only the size of a palm. She flew to Kong Ling's shoulder and sat down and said, "Do you want to listen to my advice?"

"Oh, okay, you should be the guiding elves of our group."

"Yes, you are very smart. You can simply guess my identity. It's much better than those big fools. I'll introduce you to attributes. You should see that everyone has four attributes, strength, physique, speed, and magic. The first three items can be used to improve the power of the world tree here, but there is an upper limit. If you want to break through the upper limit, you can only advance. Each time you advance, the upper limit will be increased, and the amount of improvement will be calculated based on 50% of your current attribute value. For example, your current strength is 5 points, then the upper limit after advancement is increased by 2.5. If the current is 4 points, the upper limit will be increased by 2 points."

"Oh, that is to say, the best way to advance when all attributes reach full value." Kong Ling said.

"Of course, it takes a certain amount of points to advance. The higher the level of advancement, the greater the cost. And there is a condition that a certain attribute reaches the upper limit before it can advance. Another important point is that don't expect each attribute to reach the full value and then advance. Although the perfect advancement is powerful, there are absolutely no points. The world tree will not arrange which world you go to according to your strength, but will eliminate the number of times you have been to the dimensional world, so if you cannot improve your strength in time, you will die. Moreover, other reincarnationists will also kill perfect advancers for the first time."

"Why?" Kong Ling showed a surprised look. He didn't understand why others were chasing the perfect advanced.

"It's very simple. All reincarnators are competitive. The perfect advancement is too strong. They will never be allowed to appear, which will become a huge hidden danger for them in the future. Moreover, there are super generous rewards in the annual competition. If they are not killed in advance, that annual competition will be the world of perfect evolutionists."

"So as long as you keep it confidential, it's fine."

"Hmph, it's impossible. The World Tree can exchange everything. There are definitely many props and abilities to explore attributes. Even if there are hidden props, you can still force your attributes when you meet someone stronger than you. Therefore, it is extremely difficult for people with perfect advancement to hide their identities. 99% of people here cannot achieve perfect advancement. After all, it's too difficult, but these people are afraid that those real geniuses will become perfect advancers, so they all join forces. This is also impossible."

"Okay, I understand. Is there anything else to remind me?" Kong Ling asked.

"By the way, magic energy cannot be improved by points. Only advanced, practice skills, or special treasures can improve magic energy. The last suggestion is to exchange for something that is beneficial to your survival at the beginning. Lightly improve attributes, and when you officially enter the dimension realm in the next game, the help is not particularly great. After all, the effect of improving the attributes of zero points is not particularly obvious." said the guide elf.

Kong Ling looked at her and smiled and said, "I understand, thank you for your advice."

"Well, a very polite child. Now that you have officially become the reincarnator of the World Tree, you can return to the world where you are. Remember to use the bracelet on your left hand to join the World Tree in a week. If you don't come, you will die."

"I understand, I will pay attention." Kong Ling still smiled.
