Bai Cen took the item from Xu Yanan's hand and observed it carefully, it was oval, transparent, half the size of a fist, and a small hole was opened at one end of the item, destroying the beauty of the entire item.

Looking at it, Bai Cen suddenly felt that this thing was very familiar, a flash of inspiration flashed in his mind, and he suddenly thought of something, and asked Xu Yanan in surprise.

"This thing can't be a crystal nucleus, right?"

Bai Cen's voice was obviously a little surprised, he knew the hardness of the crystal nucleus, and he thought that he had put a lot of effort into it back then, but he just didn't get it open.

"I think if we're right, it's indeed that thing."

Not to mention Bai Cen, Xu Yanan was also taken aback when he saw this thing.

"So in other words, the way to improve your strength is to drink the liquid inside?"

Bai Cen asked in disbelief, the crystal nucleus is indeed very beautiful, but no matter how beautiful it is, this thing is from the zombie after all, think about the disgusting appearance of the zombie, who would dare to eat the thing that was taken from them? I'm afraid that's the only pervert like Dr. Mad to do this kind of experiment.

"I don't know about this yet, but it seems that this is the case at the moment."

Xu Yanan was also very helpless, how could this kind of thing be drunk in his mouth?

"Think of a way, I think there must be another way."

Bai Cen said to Xu Yanan, but although he said so, Bai Cen also understood that this was just a hope, and if there was really no way in the end, then he could only drink it.

"I also hope to have, no, I'd better ask Sister Liu."

With a glimmer of hope, Xu Yanan turned around and left the mad doctor's villa, she wanted to know the use of the crystal nucleus as soon as possible.

There was nothing to say all night, and the next day Bai Cen got up early, yesterday's meal of stir-fried cabbage slices made all the people eat deliciously, if it was before the end of the world, I am afraid that few people would be willing to eat such a dish, but in the last days, this plate of fried cabbage is undoubtedly a delicacy in the world.

Although Bai Cen got up early, some people got up earlier than him, and when Bai Cen came out, most of the people in the shelter had already started the demolition project.

The roar of machinery kept coming, looking at the busy figure of everyone, Bai Cen had to thank Tianchen, because in addition to finding them a good site, Tianchen also left them a lot of tools and equipment, he was able to build so many simple houses in just a few days, it was with these tools and machinery.

"I'm going to work hard, and I'm going to have a lot of work today."

Bai Cen stretched, and then walked out of the door of the vault.

Great World Mall.

If the Great World Shopping Center is placed before the end of the world, it is definitely a well-known place, because it is located in the center of the city, it can be said that it is full of lights every day, and around the Great World, there are many hotels, KTVs, bars and other entertainment venues, so there will definitely not be too few zombies around.

I have to say that the buildings around the Great World Shopping Center have been basically destroyed, but only the Great World Shopping Center has not received any damage.

Bai Cen's goal today is here, because Bai Cen wants to get more crystal nuclei, and the first thing that comes to mind is here.

Along the way, Bai Cen can be said to have been crushed with absolute strength, and now he has 25 points of strength and 26 points of speed, with these two attributes, how can a first-class and first-class and second-grade zombies defeat Bai Cen, basically all zombies are not the sum of Bai Cen's generals.

Of course, Bai Cen has not yet encountered a first-level and third-grade zombie, but Bai Cen believes that even if he encounters a first-level and third-grade zombie, he can still win the battle, after all, he still has such a trick as the Heavenly Sword Six Styles in his hands.

Speaking of the Heavenly Sword Six Styles, the corners of Bai Cen's mouth couldn't help but show a smile, I have to say that this Heavenly Sword Six Styles are really powerful, just now, Bai Cen faced five zombies at most one time, among which there was a second-grade zombie, with Bai Cen's strength, if they fought normally, it would take at least a while to be able to solve them, but after Bai Cen used the sword light and sword shadow move, the five zombies were actually solved by Bai Cen in an instant.

With such an experience, Bai Cen can be said to have greater confidence in dealing with the Sanpin zombies.

"There are really a lot more zombies here than in other places, densely packed, and I don't know how many there are."

Coming to the vicinity of the Great World Shopping Center, Bai Cen hid in a ruin, looking at everything around the Great World from a distance, the zombies wandering on the street at this time can definitely be described as dense, which is a bit beyond Bai Cen's expectations, because there are too many, basically three steps one, five steps and one battalion, which adds a lot of difficulty to Bai Cen's plan.

But think about it, when the end of the world comes, it is the busiest time, and the surrounding shops and the temptation of snacks concentrate at least one percent of the city's foot traffic. What is one percent? Tongcheng, where Bai Cen is located, is a provincial capital, and it is not small, with a population of at least more than 3 million, and one percent of the flow of people is 30,000.

30,000 people, if they are gathered together, what a huge lineup, and according to Bai Cen's observation, I am afraid that there are more than 30,000 zombies in this posture.

"There are so many zombies, I'm afraid I have to think of a better countermeasure, if I go like this, my small physique can't stand it, but what should I do?"

Bai Cen fell into a tangle, the number of 30,000 zombies is too huge, so huge that even Bai Cen is covered in hair, in fact, Bai Cen also knows that the best way to deal with such a situation is to attack with fire, but unfortunately, in Bai Cen's space, the Molotov cocktail has been used up, and the new one has not been made, so Bai Cen is a little helpless.

"Eh, by the way, there are a lot of zombies outside, but the number of zombies inside is probably not as large as the outside, and the terrain inside is complicated, but it's a good place, just do it, I remember that there is an underground garage near here that can lead to the inside of the mall, just go in from there."
