After cleaning, more than four thousand magic cores were found on these Zhang family members, so the effort was not in vain.

But then they were faced with tens of thousands of zombie corpses, and Wang Bin and his companions were troubled again. They had no choice but to bend down and pick up the magic cores.

They were busy until nightfall before they finally finished cleaning up all the magic cores. After calculation, excluding the more than 4,000 cores belonging to the Zhang family, they had harvested a total of three elite magic cores and more than 50,000 ordinary magic cores in the past two days.

The speed at which he farms magic cores is something he never dared to dream of before. In the past, to kill an elite zombie, Wang Bin had to go back to the real world to buy all sorts of items, and then he had to combine everyone's strength and put in so much effort to get it. Now, apart from Flame, the three of them can take down an elite zombie on their own.

As for the zombie that ran into the underground parking lot, we'll have to continue searching for it tomorrow.

Everyone wasn't too tired today, but collecting magic cores all day was a bit boring. In the evening, they made a hot pot and everyone drank some beer. This guy was having a very pleasant time. If you went outside and saw the mountain of zombie corpses piled up like small mountains, many people would probably think they were on vacation.

The next morning, just as dawn was breaking, Guan Xiaoyue got up to make breakfast. Wang Bin wanted to go in early to find the elite zombie and check if there were any king-level zombies inside. If there were, they would test their strength first. If they could kill them, they would do it themselves; if they couldn't, they would send someone back to get reinforcements.

After having breakfast, everyone headed towards the entrance of the underground parking lot. The zombies in the area had been cleared out, and the surroundings seemed a bit empty. The dark underground parking lot, however, gave people a sense of dread.

Wang Bin bought a headlamp and a flashlight for everyone from the system's store. They covered each other as they entered the underground parking lot. According to the signs, there were three underground parking levels. Logically, the elite zombies should be hiding on the third level. For safety's sake, Wang Bin decided to clear the upper levels first before going down.

Because if there were king-level zombies here, they might not be able to kill them in a short time. It would be troublesome if they roared and brought all the zombies above and around to block their retreat.

As soon as Wang Bin and his group of seven arrived at the first floor of the underground parking lot, they found it teeming with zombies. Based on the density and the size of the parking lot, there were at least ten thousand zombies.

Although there are many zombies here, they are easier to clear than those above. This is because the terrain here is not as open as above, and only a limited number of zombies can attack them at once. However, their superpowers and Wang Bin's tornadoes can kill large numbers of zombies. Now, even a single ground spear from a mound can kill more than ten zombies.

However, Guan Xiaoyue found it very difficult to adapt, because she was an agile melee superhuman who relied on speed and explosive power. In such a space, she could not exert her strength at all, and in the end, she could only take a set of individual flamethrowers from Wang Bin and start spraying.

In such a confined space, this individual flamethrower was surprisingly effective. A single burst of flame immediately ignited dozens of zombies, and by spreading it around, even more zombies were burned.

In the end, A Bao also asked for a set of individual flamethrowers, because his golden iron chain was ineffective in such a space; as soon as he swung his chain, it would immediately hit the ceiling above his head.

To conserve his energy, Wang Bin simply took out his individual flamethrower and started firing as well.

With the cooperation of the seven people, they managed to wipe out all 10,000 or so zombies in just over half an hour, which was several times faster than the previous method.

"Uncle Wang, how about we lure the zombies to places like this to kill them from now on?" Abao said with a smile.

“We’re not elite zombies. The entrance is so small, we can’t possibly let them all come in,” Wang Bin said with a smile and a shake of his head. He had thought of this method as soon as he discovered that it was quite effective at killing zombies. To improve the killing efficiency, he could only lure the zombies into the narrow streets and kill them, just like he used to do with flamethrower tanks.

However, there is a downside to that. It would inevitably cause the dead zombies to pile up like small mountains, making it very troublesome to collect magic cores. This is what they call "you can't have your cake and eat it too".

Upon hearing this, A Bao and the others agreed with Wang Bin and could only sigh as they began to pick up the magic cores from the ground.

It took them a full hour to clean up all the magic cores on the ground.

Next, they cleared the zombies on the second floor. Using the same method as before, they quickly finished clearing the second floor. After eating some food and resting for a while at the entrance of the passage, they started clearing down again.

Since it was unknown whether there were any King-level zombies inside, Wang Bin also exchanged a set of individual flamethrowers for Xiao Nan and the others. They were divided into two groups to take turns spraying the zombies. After the first group's gun barrels got hot, the second group would take over. Although this would be less efficient, it was safer.

Before long, most of the zombies had been cleared. By the light, they could see elite zombies hiding in the horde of zombies with glowing red eyes. Everyone was disappointed to see that there were no king-level zombies. They had thought they could get a king-level magic core this time, but the result was disappointing.

The elite zombie seemed to sense the threat as well, and it roared loudly again.

"Damn it, this guy is calling for his men! We have to kill him right now!"

When the elite zombie roared, Wang Bin realized that they had encountered a weakling among the elite zombies. The roar it made that day was actually an attempt to call for more minions to protect it, and Wang Bin and his companions mistakenly thought that there was a king-level zombie among them.

Upon hearing this, everyone went all out. Flame and his group cleared out the zombies near the elite zombie, while Wang Bin and his group rushed towards the elite zombie, wanting to kill it as soon as possible.

Xiao Nan helped to entangle the elite zombie. Due to the terrain and the fact that many zombies nearby blocked the elite zombie's movement, Xiao Nan easily used vines to entangle it. The rest was simple. Wang Bin and Guan Xiaoyue each took care of the elite zombie and then removed the elite magic core from its head.

By this time, thousands of zombies had already run down the tunnel.

There weren't enough zombies for a few people to kill. It took them a while to deal with the zombies. When they finished cleaning up the battlefield and came to the ground, they found that it was already past three o'clock.

"Did you feel the ground shaking?" Guan Xiaoyue asked, puzzled.

"There's a possibility it could be an earthquake?" Xiao Nan said with a smile.

“I felt it too, but it doesn’t seem like an earthquake!” Wang Bin said.

After Wang Bin finished speaking, he bent down and put his ear to the ground, and immediately felt a sound like ten thousand horses galloping.

Upon hearing the sound, Wang Bin's expression changed, and he immediately flew to the top of the building. When he looked up, he was terrified. Behind and in front of them were countless zombies, an army of zombies that stretched as far as the eye could see.

"Oh no, get in the car quickly!"

Wang Bin quickly flew to the ground, immediately summoned a car, and called for everyone to get in.
