This is clearly a mutated dog, and a third-tier mutated dog at that.

Logically speaking, with the strength of the third tier, the dog should have been able to leave easily, but it was still bound by a small iron chain and never left the direction of the door.

Unless a zombie can't resist rushing up and becomes food for this mutated dog, the mutated dog won't easily leave the doorway.

"No wonder the survivors inside were able to survive; it was all thanks to the protection of this mutated dog!"

Lin Xue didn't care what was wrong with the dog, whether it was used to being chained up, or whether someone inside the building was controlling it.

As long as it doesn't involve a zombie king with intelligence comparable to humans, Lin Xue is confident she can make this trip.

Moreover, there are quite a few high-level zombies in the town, and she needs to find a way to lure them to a safe place and kill them one by one.

Collecting more mutated crystal cores will also improve the team's strength.

Thinking this, Lin Xue didn't rush to pay attention to the survivor who was calling for help, but instead rushed towards an earth-type mutated zombie on the edge.

If she remembered correctly, her sister-in-law Wan Zhenzhen had an earth-type spiritual root.

Although her sister-in-law's spiritual roots were rather mixed, Lin Xue still hoped to improve her own family's strength first.

Even after the original owner's husband passed away, the Han family did not mistreat her.

Even now, they still treat Lin Xue like family, and Lin Xue can't pretend not to see this pampering.

Since the Han family treats her as one of their own, Lin Xue naturally won't treat the Han family as outsiders either.

First, train the people with spiritual roots from the Han and Lin families, then give the rest to the bodyguards, and finally the members of the Blade Squad.

Don't blame Lin Xue for being selfish; in this unpredictable apocalypse, no amount of caution is too much.

"boom!"

He kicked the earth-type zombie, sending it flying far away and crashing deeply into the outer wall of a house.

The next second, Lin Xue quickly went up and kicked it again, sending the zombie flying into the house.

Lin Xue ducked down and squeezed into the large hole created by the earth-type zombie.

At this moment, the earth-type zombie had stood up again and was looking in Lin Xue's direction.

"Hiss~"

Only now did Lin Xue realize that the earth-type zombie's mouth was empty; it didn't have a tongue at all.

Lin Xue didn't want to know how his tongue was lost; she just wanted to end the fight quickly. The moment she rushed into the house, she sensed several auras rushing towards her.

Earth element is known for its high health and defense.

Talismans like Frost and Flame are unlikely to harm earth-type zombies.

Lin Xue kicked the earth-type zombie away again, then shoved the lightning-attracting talisman into the zombie's mouth.

After inserting the lightning-attracting talisman, she quickly retreated, then chanted an incantation to detonate the talisman.

"Bang!"

The earth-type zombie exploded, and Lin Xue quickly picked up the fallen yellow crystal cores.

Then he darted to the second floor and used the second-floor window to climb onto the roof.

They quickly left the area and rushed into another house.

"Crack! Crack! Crack!"

A zombie covered in barbs followed them in. This zombie was green all over, and its five fingers were no longer human hands.

It looked like it was dragging five vines and being flung towards Lin Xue.

Lin Xue rolled away to dodge the attack, then quickly circled behind the zombie and kicked it in the back.

"boom!"

Lin Xue kicked the zombie into the wall again, but the vines on his hands grew endlessly, wrapping around her.

This wood-type zombie is much more difficult to deal with than the earth-type zombie. It seems to be able to sense the fluctuations in the air, and no matter which direction Lin Xue runs, the wood-type zombie's vines can accurately follow.

Lin Xue took out a long sword from her spatial storage and began slashing at the outstretched vines.

Although Lin Xue cut off many of the vines, this wood-type zombie seemed to be able to continuously regrow new vines.

However, the speed was getting slower and slower, as if it was running out of steam.

Seeing that this method was feasible, Lin Xue quickened her pace, swiftly severing the newly grown vines, and then approached the wood-type zombie.

"With the final strike, Lin Xue directly attached a lightning-attracting talisman to the sword, and with one strike, the wood-type zombie was instantly split in two!"

Picking up the fallen wood-type crystal core, which was emerald green, it seemed that this zombie was about to break through to the third tier.

Lin Xue was just a little short of obtaining a third-tier crystal core.

She currently has quite a few ordinary crystal cores in her space, which were left behind when she used lightning to strike zombies.

Lin Xue gave one part to Tang Wenwan, who already possessed supernatural abilities, and the other part to Lin Zhenyuan.

She can use it once her father awakens his superpower.

Lin Xue tried it herself and found that she could also absorb the energy in the crystal core, and the energy in the crystal core was purer than the spiritual energy absorbed from the air.

Besides the crystal cores for her parents, Lin Xue also kept some for herself, which she planned to take back to the Main God Space for future use in the world.

As for the training matters within the team.

Lin Xue stated that she was not their parent(s), and that anyone other than their parents and brothers who wanted crystal cores could go out and kill zombies themselves.

Lin Xue doesn't even intend to spoil her own brother.

Aside from offering some initial assistance when her abilities were too low to be suitable for combat, once her abilities level increased, she would still have to rely on herself to fight zombies and train to level up.

In the blink of an eye, only a few minutes had passed since the two zombies were dealt with.

Lin Xue had already sensed that several zombies were surrounding her.

One-on-one situations are relatively easy to resolve, but Lin Xue said she didn't want to take the risk of fighting a group.

Although there's a saying that fortune favors the bold, Lin Xue's mission this time was to protect Han Mingxuan, and she clearly understood the priorities.

After all, Lin Xue valued the 629 system more than the crystal core.

After quickly shaking off the tail behind her, Lin Xue waited until the high-level zombies separated before catching up with the closest third-tier gold-type zombie.

Logically speaking, the gold-type zombie is the most difficult to deal with among all zombies.

But Lin Xue didn't follow the usual path; she directly used lightning-attracting talismans and rain-bringing talismans to electrocute the metal-type zombie.

They successfully obtained a gold-type crystal core. This time, the commotion was relatively small, and no other zombies gathered around.

Lin Xue secretly followed another water-type zombie. Wouldn't water explode when it comes into contact with lightning?

Lin Xue discovered that among her many offensive talismans, only this lightning-type talisman was the most effective.

Lightning-type talismans can be used against almost all types of zombies.
